A little twist on traditional moussaka
We can all agree that moussaka is Greek comfort food at it’s finest!
And, yes, the popular flavor-packed eggplant casserole, topped with creamy bechamel sauce, is a labor of love. There are typically several layers and a few steps involved. But if you’ve ever made it, you know that it’s totally worth the effort for a special family dinner.
I shared my earlier Greek-style moussaka recipe and my Egyptian-style moussaka, both made with a juicy meat sauce. Since then, I have gotten many requests for a meatless version.
I’ve been playing around with different ingredients, and I finally have the BEST vegetarian moussaka that is as scrumptious and tasty as my meat-lovers’ version.
This vegetable moussaka casserole is made of layers of quick-roasted vegetables; a tasty rich tomato sauce with black lentils in place of ground meat; and creamy bechamel to top it all.
Let’s dive more into this vegetarian eggplant moussaka, what’s in it, and how to make it!
Vegetable moussaka components
It helps to think of this vegetarian moussaka recipe as having three components: vegetables; a vegetarian sauce; and a top layer of creamy bechamel.
To make the best vegetarian moussaka, it took some tinkering around with ingredients to make a version that felt just as hearty and unctuous as my earlier meaty beef (or lamb) version.
To really knock this recipe out of the park, I had to find the PERFECT meat substitute that held up well in the sauce and provided a great hearty texture. The verdict? Black Beluga lentils.
Black lentils are petite and cook fairly quickly. They have a wonderful, creamy consistency; full-bodied and earthy flavor. Not to mention, they’re a great source of protein, polyphenolas, iron, and fiber…(find black lentils here.)
In this vegetarian moussaka, a scrumptious tomato-lentil sauce–with a fragrant pinch of nutmeg and cinnamon–is nestled between quick-roasted vegetables, including tender eggplant. And of course to top our eggplant casserole is none other than creamy bechamel sauce!
What vegetables go in vegetarian moussaka? And what else do you need to make it?
The components of this vegetarian moussaka recipe are not hard to make. There are three components as I mentioned earlier: vegetables, sauce, and a top layer of bechamel. Let’s walk through them some more:
1. Roasted Vegetables
For this vegetarian eggplant moussaka recipe, eggplant remains the star. I also add 2 to 3 russet potatoes and 2 zucchini. All the veggies are sliced the long way to create our different layers.
Eggplant needs a little extra TLC. So we start with giving our eggplant slices a sprinkle of kosher salt and leave it alone for 20 to 30 minutes to “sweat out” any bitterness.
To prepare the vegetables for our vegetarian moussaka, we give them a quick roast in hot oven for 15 to 20 minutes.
2. Tomato-Lentil Sauce
This lentil sauce is my vegetarian replacement for meat sauce.
It incorporates cooked black bluga lentils with crushed tomatoes and aromatics like minced garlic, onions, a pinch of nutmeg and cinnamon. After a brief simmer, this sauce is hearty and creamy, you won’t miss the meat.
3. Bechamel
We’re not taking shortcuts here with this roasted vegetable moussaka. The very top layer of creamy bechamel is essential, making this dish as scrumptious and comforting as they come!
Although bechamel sounds scary and intimidating, it is fairly easy to make (we’ve done it before in this pastitsio recipe.) Essentially, you make a roux with flour and quality extra virgin olive oil (some use butter, but I prefer olive oil here.) Let it brown a tad, add in warm milk (bit-by-bit), whisk, season, and add in tempered eggs, while continuing to whisk a little bit more until nice and smooth.
Let’s get to the step-by-step…
How to Make this Vegetarian Moussaka – Step-by-Step
1. Preheat your oven to 400 degrees F and salt the eggplant. Slice eggplant length-wise. Sprinkle with kosher salt on both sides and place on a large sheet lined with paper towel. Let eggplant “sweat” for 20 to 30 minutes or so, while you work on other things. This will help the taste and texture of the eggplant. When ready, pat excess moisture.2. Make the bechamel. Pour extra virgin olive oil in a pot and let heat till shimmering but not smoking. Add the flour, salt, and pepper and stir around until the mixture turns a light golden brown. Slowly add your warmed milk, while whisking continuously.
In a small bowl, whisk a small amount of the hot bechamel mixture with the 2 eggs. Then return all to the pan with the remaining bechamel mixture. Continue to stir or whisk the mixture bringing to a gentle boil for just 2 more minutes. Taste and adjust salt and pepper. Remove from heat and allow to cool and thicken a little more (you should have a creamy, thick and smooth bechamel sauce).
Tip: if your olive oil and flour mixture is too dry and looks chunky, drizzle in a little more olive oil until it looks like a smooth paste.
3. Prepare the tomato-lentil sauce. First, saute the onions and garlic briefly until they smell delicious. Add your already COOKED black lentils, tomatoes, and broth. Season and add spices. Let it come to a boil and then over part way with a lid, turn the heat down, and simmer for 15-20 minutes.
How to cook black lentils for this sauce? To cook the black lentils first before you add them to sauce, begin with 1/2 cup dry black lentils. Add 1 1/2 cups water. Bring to a boil, then cover and reduce heat to medium-low. Simmer until lentils are tender (about 20 to 25 minutes, adding more water as needed to keep the lentils submerged.) Drain.
4. Roast the Vegetables. While the lentil sauce is simmering, take your dry eggplant and place it with the potatoes and zucchini on lightly-oiled baking sheets (you’ll need more than one baking sheet to spread the veggies in one layer.) Sprinkle the zucchini and potatoes with salt (eggplant is already salted.)
Give the veggies a brush of extra virgin olive oil. Roast in heated oven for 15 to 20 minutes.
5. Assemble to moussaka. You have made it, time to put it all together!
Ladle a little bit of the lentil sauce on the bottom of a lightly oiled casserole pan. Layer the roasted veggies on top…
Now add the rest of the tomato lentil sauce…
Add bechamel on top. Be sure to spread the bechamel and smooth it out with the back of a spoon.
6. Bake! The vegetarian moussaka casserole can take somewhere between 45 minutes to 1 hour in your heated oven.
You’re looking for the top bechamel layer to turn a nice golden brown (if needed, place it under the broiler for a tiny bit, watching very closely to make sure you get the color you want.)
Can you eat eggplant skin?
Many people think eating eggplant skin is a no-no, but the exact opposite is true. When eggplant is cooked, the skin becomes tender and soft and is great to eat. It packs lots of vitamins, minerals, and fiber.
(If you need to, you can partially peel the eggplant leaving just some of the skin on.)
Why do you salt eggplant?
The first step I take whenever I work with eggplant, whether to fry or roast it, is salting it. This is important for two reasons:
First, it allows a lot of the moisture in the eggplant to release. If you cook eggplant without salting and patting dry with paper towels, your moussaka can get watery and make your dish soggy and less flavorful. Nobody wants that!
Second, eggplant tends to be a little bitter and the salt counteracts that bitterness. You are left with a much sweet and milder slice of eggplant after salting.
To save time in this recipe, as you saw in the step-by-step above, I start by salting the eggplant then move on to working on the bechamel etc. if you are going to make moussaka, do it right!
Can this vegetable moussaka be prepared ahead?
Despite the number of steps involved, this vegetarian moussaka is not too complicated to prepare. And, even better, you can prepare parts of this recipe ahead of time. You have a couple of options…
You can cut and roast all your veggies, make the tomato lentil sauce, and even prepare the bechamel 1 night in advance (I’ve done it 2 nights in advance as well, but since there may be leftovers, I try not to work too far ahead.)
You can store the different components in separate containers in the fridge, and when you are ready, assemble and bake!
If you decide to make the bechamel in advance, you will need to warm it up in pot before you can pour it on the top of your moussaka. As it sits in the fridge, it will get very thick and slightly gelatinous. You may need to add an extra splash of milk to thin the sauce out and get it back to its pourable consistency.
If you don’t want to worry about this, just make the bechamel right before you are going to assemble. That way it’s fresh and requires no extra steps.
Leftovers
You’re likely to have leftovers, which is great because it tastes just as good the next day. You can place them in an airtight container for about 3 days.
Can you freeze vegetarian moussaka?
If you need to freeze your leftovers, it is a perfect solution for making the vegetarian moussaka last longer. It will keep well for up to 1 month in the freezer. Plus, no thawing needed, it can be baked right away from freezer to oven!
What do you serve with this eggplant casserole?
This type of eggplant casserole is a full meal in and of itself. But if you are looking for a little something extra, add a big Greek salad or simple Shirazi salad to start.
Still want some meat? Server a few Keftedes or a couple skewers of souvlaki along.

Instructions
Instructions
- Heat oven to 400 degrees F.
- Salt Eggplant. While oven is heating, spread eggplant slices on a large pan lined with paper towel and sprinkle with kosher salt set aside for 20 to 30 minutes. Pat dry with paper towels
- Make the Bechamel. While the eggplant is sitting, work on the bechamel sauce. In a large saucepan, heat olive oil over medium-high heat until shimmering but not smoking. Stir in flour, salt and pepper. Cook until golden (if needed, added a little more olive oil). Gradually add the warmed milk, whisking continuously. Continue cooking, stirring occasionally, over medium heat for 5 to 7 minutes. Add nutmeg. In a small bowl, whisk a small amount of the hot bechamel mixture with the 2 eggs. Then return all to the pan with the remaining bechamel mixture. Continue to stir or whisk the mixture bringing to a gentle boil for just 2 more minutes. Taste and adjust salt and pepper. Remove from heat and allow to cool and thicken a little more (you should have a creamy, thick and smooth bechamel sauce).
- Make Lentil Sauce. In a cooking pot or large non-stick pan, heat 1 tbsp extra virgin olive oil over medium heat. Sautee onions and garlic for a brief 3 to 4 minutes till fragrant, tossing regularly. Stir in COOKED black lentils, crushed tomatoes and broth or water. Season with a dash of kosher salt, and add oregano, nutmeg and a small pinch of ground cinnamon. Bring to a boil, then lower heat and cover only part-way. Simmer for about 15 to 20 minutes or so.
- Bake Vegetables. While lentil sauce is simmering, bake the vegetables. Arrange the potatoes, zucchini and eggplant slices on lightly oiled baking sheets. Brush with extra virgin olive oil. Bake in heated oven for 15 to 20 minutes just until tender.
- Assemble Vegetarian Moussaka in a 9 x 13 baking dish. First, pour a bit of the lentil sauce on the bottom of the baking dish and spread. Layer the vegetables on top. Add the remainder of the lentil sauce. Finally, spread bechamel sauce on top, making sure to smooth it out well with the back of a spoon.
- Bake. Place moussaka casserole on the middle rack of your heated oven. Bake for 45 minutes or until top bechamel layer turns golden brown.(If needed, place under broiler and watch very carefully till top turns a nice golden brown.)
- Remove from heat and let sit for at least 20 minutes before cutting and serving. Cut into 12 squares. Enjoy!
Notes
- Cook’s Tip 1: Do not skip salting the eggplant. This step helps season the eggplant, while allowing it to sweat out any bitterness. It also helps relax it’s spongy texture.
- Cook’s Tip #2: Once moussaka is baked, be sure to let it rest for about 20 minutes before cutting and serving. This allows the bechamel topping to settle so it’s easier and less messy to serve.
- Prepare Ahead Tips: You can prepare each component of this recipe–bake the veggies, make the bechamel topping and the lentil sauce one night in advance. Store each in separate containers in the fridge and assemble when you are ready to bake. If you decide to make the bechamel in advance, you will need to warm it up in pot before you can pour it on the top of your moussaka. As it sits in the fridge, it will get very thick and slightly gelatinous. You may need to add an extra splash of milk to thin the sauce out and get it back to its pourable consistency.If you don’t want to worry about this, just make the bechamel right before you are going to assemble. That way it’s fresh and requires no extra steps.
- How to cook black lentils for this sauce? To cook the black lentils first before you add them to sauce, begin with 1/2 cup dry black lentils. Add 1 1/2 cups water. Bring to a boil, then cover and reduce heat to medium-low. Simmer until lentils are tender (about 20 to 25 minutes, adding more water as needed to keep the lentils submerged.) Drain.
- Leftovers? Store leftovers in the fridge, tightly covered, for up to 3 days.

I enjoyed looking at the eggplant recipes, and plan to try some of them. Thanks for putting them in a collection. However, I was wondering why the vegetarian moussaka recipe didn’t include potatoes, like the more traditional one with meat.
Thanks, Nancy! That’s just Suzy’s personal twist on vegetarian moussaka. You could certainly add potatoes, if you’d like!
I’ve made this with green lentils bc black were not readily available. Just cook the lentils per their package and then follow this recipe. Great for entertaining vegetarians. No one will miss the meat!
This was so very delicious! Full of layers of flavor and texture.
I took the plunge and made for company – one vegetarian guest. All the guests
loved it and when offered took some home most eagerly.
I LOVE eggplant, so it’s always nice to try a new way.
Thanks again, Suzy!
I am a big fan of the mediterranean dish and I use recipes on a weekly basis. However, I am sorry to give this recipe an inferior rating. I followed the recipe exactly. My husband and I are vegetarian and neither of us liked this dush. Too bad because I spent hours making it and it makes a huge amount. We’re throwing the remainder from tonight’s dinner in the garbage.
what didn’t you like about it?
Having recently been diagnosed with high cholesterol, I’m on the lookout for high fibre, low fat meals.
I made this for dinner tonight. I made the base and veg yesterday and assembled and added and cooked the complete dish today.
Absolutely delicious! I didn’t know you could make a roux with olive oil!
Thank you so much for this great recipe. I have shared to a lowering cholesterol page.
So glad you loved it, Pauline! Thanks for sharing it with others!
Think this is one of my top five recipes! I used a tin of regular lentils and 4 or 5 mushrooms chopped up in the sauce, just because. But that bechamel sauce… so very, very good. I’ve never made it without butter before and this was so much easier and tasted amazing!!
Thanks so much, Juanita!
Going to make today. As we are only 2 at the moment will freeze as well. Do I freeze before baking or only after?
Maybe bake in 2 separate dishes?
Hi, Maude. For best results, we recommend freezing after the moussaka is assembled (before baking). When you’re ready to eat it, you can bake directly from freezer… no need to thaw! You can freeze after baking, though, if you prefer. Either way will work.
I’ve made this a few times now and love it.
I do make some adjustments:
Lentilsauce:
1) I add a bit more oil and a bit of butter (1 tbsp)
2) I substitute 1-2 dl og the stock for red wine – makes a huge difference for flavor and depth
3) 3 tbsp tomato paste (important)
4) Usually some finely shredded carrot, chopped cellery stalk.
5) Bit of smoked paprika
6) Often prepare one day ahead so I can let it simmer for long
Bechamel:
1) If I have – shredded cheese
2) Lemon zest – gamechanger!
I find the bechamel is waaaay too much.
So I usually make double the vegetables and double the lentil sauce, but only one bechamel. Then prepare in two dishes and freeze one as it is a time consuming recipe. The listed time is not enough.
Hi there, Devin here from the Mediterranean Dish team. Thank you for sharing your tweaks to this recipe!
It was our first time trying this recipe and we used your recommended tweaks. Turned our delicious! Thank you!
I love this recipe and have made it many times. Was the original recipe made with a yogurt bechamel!? If it was because I loved it, could you add the alternative way to the recipe? Thank you for all your wonderful recipes Suzie 😊
I’ve cooked this several times now, it’s excellent.
Thank you for sharing.

This recipe is AMAZING! Worth every minute of prep… seriously, one of the best moussaka’s I’ve ever head… Thank you!
I made this last night and it was better than the meat based moussaka I ate in Athens. I used green lentils because I couldn’t find black lentils here. Everything else was the same. Oh and we put feta on top. Really delicious! Thank you!
Awesome! Thank you so much, Patti!
Made as directed but the results came out fairly watery and bland. I think that this was ‘converted’ from the version with meat without really accounting for how much flavor & fat the meat adds to the dish. If I made this again, I’d stick the potatoes and zucchini under the broiler to get a more roasted flavor on those, and try to add some additional flavor to the sauce (something umami like soy sauce, maybe?).
I use this basic recipe for Moussaka with either Beyond or Impossible ground beef substitute and if I don’t tell anyone they never realize it is a vegetarian dish. If I use Vegan Cheeses I can get it to a Vegan dish this way. The first time I tried it one of the guests at the friends house knew it was Vegan and couldn’t believe it wasn’t ground beef. I grew eating from some people in our area who immigrated from Greece and they used ground lamb. Regardless it is a great dish and wonderful to serve either way.
Thanks, Pam!
This recipe for Vegetarian Moussaka is fabulous!!!! I have made it several times for company and will be taking it to our family Thanksgiving feast. I normally do all the prep work the day before and do the topping/sauce day of the dinner. I am a huge fan of Suzy’s recipes and cookbook. Enjoy!
Thank you so much, Lisa!
I’ve made it several times and I really enjoy it. I salt the eggplant and fry it a bit but I am not sure what to do with the salt? I try and brush it off after the eggplant is out of the oven, but I am not very good at it. So the entire dish becomes rather salt. Do you rinse it off?
Hi, Marie. Suzy doesn’t typically rinse off the salt. She just blots the eggplant with a paper towel after 20-30 minutes and that always does the trick for her. If it’s too salty for you, maybe just reducing the amount of salt you use a bit will help.
