I love classic lasagna as much as the next person, but I’m all for a fun twist on old favorites–from lasagna soup to lasagna roll ups to this eggplant lasagna!
The gist: this vegetarian eggplant lasagna carries all the comforting Italian flavors we love–complete with layers of a flavor-packed cheese mixture with spinach and fresh herbs + red pasta sauce (you can use store-bought marinara for a shortcut, or try my homemade spaghetti sauce). But in place of the noodles, we have velvety tender roasted eggplant slices!
Admittedly, I’ve never met an eggplant casserole I didn’t enjoy (moussaka anyone?) Actually, I’m a big fan of eggplant recipes in general, which you’ll see by all the different ways I use it in my cooking!
But there is something extra tasty and comforting about this recipe! And I’m telling you, this low carb lasagna with roasted eggplant is as hearty and delicious as any good lasagna recipe should be.
If you watch my video below, you’ll see how easy it is to make. And I’ve included some tips and make-ahead ideas, if you need them!
How do you slice eggplant for lasagna?
In this recipe, eggplant is low carb option that replaces the pasta sheets in this recipe. With that in mind, the best way to cut it is in long slices or planks that are 1/2-inch thick.
You’ll see in my video below that I also trimmed the eggplant and did not use the very short sides.
And you do not have to peel the eggplant before making this eggplant lasagna recipe.
Prepare the eggplant
Before you assemble the lasagna casserole, you have two easy steps to prepare the eggplant:
- Salt the eggplant (optional). The big debate, to salt or not to salt the eggplant before cooking. Most eggplant is really not that bitter, but I still like to salt my eggplant slices and let them “sweat” for a few minutes while I prepare the rest of the ingredients. This is a great way to infuse the eggplant with flavor, and the salt does break the spongy texture a bit. Just be sure to wipe off all the excess moisture and salt well before cooking.
- Roast the eggplant. You do need to cook the eggplant planks a bit so that they become pliable enough to use in place of lasagna noodles.
But unlike eggplant parmesan where we the eggplant is breaded and fried, for this low carb eggplant lasagna, we simply need to roast it. Roasting breaks eggplant’s spongy texture and concentrates its flavor, turning it into something fragrant, delicate and almost addictive (this is why I make my roasted eggplant recipe often around here).
How to make eggplant lasagna: step-by-step
(print-friendly recipe with ingredient list and video below)
- Slice and salt the eggplant. You want slices (or planks) that are about 1/2-inch thick. Salt the eggplant and leave it alone for 20 minutes or so (This is totally optional as I explained earlier). Wipe the eggplant well to dry and remove excess salt (you can also rinse it if you want, but you’ll have to make sure and dry it well).
- Roast the eggplant. Grab 1 or 2 large sheet pans and brush with a bit of extra virgin olive oil. Arrange the eggplant slices in one single layer. Roast in the oven at 400 degrees F for about 20 minutes or until the eggplant is soft and pliable
- Make the filling. While the eggplant is roasting, put together the ricotta filling. In a mixing bowl, combine 1 beaten egg with the ricotta (I used part-skim), 1 cup shredded mozzarella, ¼ Parmesan, garlic, oregano, 10 ounces thawed spinach (make sure you get rid of all excess water), chopped parsley and basil. Season with a bit of kosher salt and black pepper. Mix really well to combine Add a small pinch of kosher salt and black pepper to your liking. Mix well to combine.
- Assemble the eggplant lasagna. Grab a 9 x 13-inch baking dish. Pour a little bit of the pasta red sauce on the bottom (about 1/2 cup) and spread it. Arrange a few eggplant slices on the bottom of the baking dish (whatever will fit to cover the bottom of the dish; 4 to 6 slices).
Spread a layer of the ricotta filling (about 1/2 of it), then spread a thin layer of the pasta sauce. Repeat the process in the same pattern until you’re finished.
Top with a final layer of sauce and follow with the remaining ½ cup mozzarella cheese and ¼ cup of Parmesan. - Bake! Cover the dish tightly with foil. Bake in the oven at 375 degrees F for 15 to 20 minutes, then carefully uncover and return to the oven to bake for another 10 to 20 minutes until the top layer of cheese is nice and melted and some edges of the vegetarian eggplant lasagna turn a nice golden brown.
- Let rest 10 minutes before cutting it up! Allow the cheese and everything some time to settle, if you try to cut it while it’s hot, it will be messy. Garnish with a bit of fresh parsley or basil, if you like.
Prepare Ahead, Leftovers and Storage:
- To prepare ahead: You can roast the eggplant and prepare the ricotta cheese filling 1 day in advance. Keep them refrigerated in separate containers. Assemble just before baking. When ready to bake, let the lasagna stand at room temperature while you preheat the oven.
- Leftovers & Storage: Refrigerate leftovers for up to 4 days. Rewarm, covered, in a medium heated oven.
- To reheat: Warm, covered in a 350 degrees heated-oven
Can you freeze it?
I’m not a fan of freezing this eggplant lasagna as eggplant can become too watery and mushy when frozen. And in the absence of sturdy noodles to hold the casserole together, it will be more challenging.
What do you serve with vegetarian eggplant lasagna?
To me, this dish can stand alone as dinner just add your favorite salad and call it good!
Italian Salad would be an easy choice, but if you’re looking for another light and fresh salad, try my lazy tomato and cucumber salad or this lemony arugula salad. For something more hearty, try my fresh Mediterranean bean salad.

Eggplant Lasagna Recipe
Ingredients
- 2 to 3 eggplants (about 1 ½ pounds), sliced lengthwise into ½-inch thick slices (about 12 slices)
- Extra virgin olive oil
- Kosher salt
- 1 large egg
- 1 15-oz tub part-skim ricotta cheese
- 1 ½ cup park-skim mozzarella cheese divided
- ½ cup grated Parmesan cheese divided
- 3 garlic cloves minced
- 1 teaspoon dried oregano
- 10 oz frozen spinach, thawed and fully dried (wring out all the water)
- 1 cup packed chopped fresh parsley
- ½ cup packed chopped fresh basil ⅔ ounce
- Black pepper to your liking
- 2 cups prepared pasta sauce of choice (Homemade or store-bought)
Instructions
- Season the eggplant slices on both sides with kosher salt and set aside for 20 to 30 minutes (if you don't have the time, this step can be optional).
- Meanwhile, preheat the oven to 400 degrees F and position a rack in the middle.
- Wipe the eggplant slices very well with a paper towel (you want to dry it well and remove any excess salt), then arrange on lightly oiled baking sheet (or two if needed). Brush the top of the eggplant with extra virgin olive oil. Roast in the heated oven until the eggplant softens and becomes pliable (about 15 to 20 minutes or so).
- While the eggplant is roasting, prepare the ricotta filling. In a mixing bowl, beat the egg. Add the ricotta, 1 cup mozzarella, ¼ Parmesan, garlic, oregano, spinach and chopped herbs. Add a small pinch of kosher salt and black pepper to your liking. Mix well to combine.
- Remove the eggplant from the oven. Lower the heat to 375 degrees F.
- Prepare a 9 x 13-inch baking dish. Pour a bit of the pasta sauce (about ½ cup or so) and spread it out into one layer. Lay a few eggplant slices (anywhere from 4 to 6 and it’s fine if they overlap a bit). Spread 1/2 of the ricotta filling, then spread a thin layer of the sauce. Repeat the process in the same pattern. Spread the final layer of sauce and follow with the remaining ½ cup mozzarella cheese and ¼ cup of Parmesan.
- Cover the dish tightly with foil. Bake in the heated oven for 15 to 20 minutes, then carefully uncover and return to the oven. Bake for another 10 to 20 minutes or until the cheese has melted and the edges of the lasagna turn a nice golden brown.
- Let the lasagna rest for 10 minutes before cutting and serving.

Hi, how about using fresh spinach and/or Swiss chard? Will this work? As I always feel fresh is best – where ever possible.
Hi, Kim. Either should work. If you are going to go with fresh, though, I would blanch it first, and then be sure to squeeze all the water out.
Wow! I can’t believe I just made this delicious eggplant lasagna. You made me feel like I can cook. We had this as part of our Thanksgiving meal. This recipe is definitely going to be used often in our home. Thank you for sharing!!
You are very welcome, Aleta! Thanks for taking the time to comment and review!
Hello! I’m hoping to get some assistance so that my dish isn’t ruined. I forgot to cook off eggplant before assembling and it’s still a little crunchy and not too easy too cut and it was a little watery. I placed a cast iron pot on it hoping some of the water will come up so that I can pour off. But what can I do not loose any flavor and get the eggplant all the way cooked? Any suggestions are greatly appreciated because it tastes so good!!
Hi, Shannon. Oh, no! This is a tough one. I like your idea for trying to drain off some excess water. To try to cook the eggplant a bit more, I would keep the lasagna covered and keep baking… maybe at a lower heat so the cheese doesn’t burn.
I made this recipe for my family today and it went over AMAZINGLY well! We’re Italian and know lasagne! Nobody minded the eggplant in place of the lasagne noodles, and some were not nuts about eggplant in general. It was *delicious*. I will definitely make it again in a heartbeat. One small adjustment: I went overboard on the sauce and it ended up just a bit soupy. Crusty bread took care of that, but I would reduce that a bit in a next iteration…and there definitely will be more of this in our future!
Yay! This is so great to hear! Thanks, Irene!
Made this for lunch and OMG good. It all works together and will make again. I used your spaghetti sauce recipe for it. Be a shame to make it with anything but. I would advise anyone to reduce the spaghetti sauce quite a bit to prevent a watery lasagna.
I adapted for 1 person. Used my homemade sauce and as I had no fresh herbs on hand I used dried. Also used fresh baby spinach and one aubergine. It was delicious. Made enough for two so froze the rest.
Making it now for the first time. Step 4 stumped me as I read 1/4 Parmesan and not 1/4 cup Parmesan. Figured it out. Now I can’t wait to cook it and eat it.
It looks delicious and a better alternative to pasta. I will try it today.
Thank you
Hope you loved it, Michael!
I have done dish more than 10 times. Excellent!
Was so good. And great for being on a low cholesterol diet.
Fantastic! My husband and I were so sad when we finished the pan!
The prep time estimate of 30 minutes is inaccurate. First you have to cut the eggplant, lay it out on racks, salt it on both sides, then sweat it for 20-30 minutes, wipe it down then cook it for 20 minutes. That’s at least 50 minutes right there. It took me a good hour + to make this recipe! Worth it, but you can’t just whip it together in 30 minutes.
I made this today and its absolutely gorgeous
My guests and I enjoyed this very much. I followed the recipe exactly. I roasted the eggplant the day before, and next time I will also prepare the cheese mixture in advance. Otherwise, it is too much for me to do all in one day. So the spinach wasn’t too watery, I spread the thawed spinach out on a cookie sheet and put it in a 200-degree oven (Fahrenheit) for about 20-30 minutes, stirring occasionally. It did not cook, but it did get rid of all the excess water. I would make this recipe again.
I just wrapped the frozen spinach in a kitchen towel and microwaved it for a minute or two. Then, I just pressed out the excess water by hand.
Made dish 6x and absolutely delicious, have added meat too. Thanks for sharing!
So glad you love this one, Gladys!
Hi all,
Could you please add a function to switch to metric for us non-imperialists?
The recipe looks cool, and I am soon going out the door for the ingredients, but first I am going to convert all the measurements…
But I am sure it is worth it 🙂
Thanks for the feedback, Bas. We’ve been looking for a conversion tool that works well with our website, but haven’t quite found the right one, yet. Apologies for the inconvenience. We’ll keep researching. In the meantime, I hope you enjoy the eggplant lasagna!
I made this recipe yesterday and it was AMAZING! I live in the Canadian Rockies in a ski town and my guests and family loved it! Thank you! Only thing I would do different is use Fresh spinach instead of frozen…..it was a “tad” watery (not bad) even though I rung out the thawed frozen spinach……even so it was truly fantastic!
Signed,
The Happy Canadian
