The secret to never-boring chicken breast!
Boneless skinless chicken breasts are a convenient ingredient that’s a staple in most kitchens. But let’s face it, sometimes it can be hard to get excited about another chicken breast dinner.
If that’s where you are, let me tell you: slicing a chicken breast open and stuffing it with a little bit of melty cheese and loads of Mediterranean flavors, is next level delicious!
Best part? You can make this stuffed chicken breast recipe in just over 20 minutes!
What do you stuff chicken breast with?
The great thing about stuffed chicken breast recipes is that they’re so easy to customize based on your mood and what you have in your pantry. The possibilities are endless! I wanted to add a bit of Mediterranean, slightly Italian, flare to my filling. Here’s what I used to make the filling for this stuffed chicken recipe:
- Cheese: a combination of 1/2 cup ricotta and 1/4 cup each part-skim mozzarella and grated Parmesan (melty tasty goodness without overwhelming the stuffed chicken).
- Spinach: because we’re using 5 ounces of thawed frozen spinach, we really don’t need to spend time cooking it. It can just go right into the filling mixture, but be sure to wring out all the liquid.
- Aromatics and seasoning: Sundried tomatoes, fresh garlic, parsley, and oregano: Mediterranean favorites that give our cheese and spinach filling so much flavor!
- Extra virgin olive oil. The olive oil also helps to moisten the filling mixture so that everything is well-incorporated.
- Walnuts! Now this is the secret ingredient here, and yes, it’s another Mediterranean favorite. I used 3/4 cup of walnut hearts. The walnuts (finely chopped) truly elevate the filling by adding texture, flavor, and nutrition.
The secret ingredient: walnuts!
When it comes to walnuts, many of us think of sweets like banana walnut bread or apple strudel. But in my mother’s Mediterranean kitchen, they were also used in a lot of savory dishes (you may have come across my Muhammara walnut dip and this fried eggplant recipe).
So when I was thinking of a way to amp up the flavor and add more texture and substance to the filling for today’s stuffed chicken, walnuts were a no brainer. You’ll love the subtle nuttiness and extra crunch in this recipe!
Fun fact! For those who follow the Mediterranean diet, incorporating walnuts in your cooking or even as a daily snack can have some great benefits. I recently attended an amazing virtual harvest tour with California Walnuts and learned that one ounce of walnuts is a powerhouse of important nutrients for optimum health, including: 2.5 g of ALA Omega-3 fatty acids, 4 grams of protein, and 2 grams of fiber. (Lots more good information here).
Lucky for us, there is no shortage of quality walnuts here in the States, thanks to the fertile soils of California’s central valley!
Cooking this spinach stuffed chicken breast is fairly easy. Once you mix the filling ingredients together, make a little “pocket” for the filling in each chicken breast. From there, cook the chicken in a pan or cast iron skillet for about 10 to 12 minutes in total. Here’s how it goes.
How to make spinach stuffed chicken breast: step-by-step
(print-friendly recipe just below)
- Make the filling. In mixing bowl, combine the ricotta, mozzarella, Parmesan, finely chopped walnuts (save a bit for garnish), spinach, sundried tomato, parsley, garlic, and oregano. Add a pinch of kosher salt and drizzle of good extra virgin olive oil, mix well with a spoon.
- Cut a “pocket” into each chicken breast. Season the chicken with kosher salt and black pepper. Then, you’ll want to make a horizontal cut about 3 to 4 inches or so. Place a hand on the chicken breast and use a good knife to cut through the thick part, but cut only cut ¾ of the way in so you don’t split the breast open completely (remember, you’re making a pocket).
- Stuff the chicken breasts. Divide the filling among the chicken breasts. Open up the “pocket” and spoon in a bit of the spinach and cheese mixture.
- Cook! In a large pan, heat up about 3 tablespoons of extra virgin olive oil. Add the chicken breasts in (make sure they are arranged in one single layer. If your pan is not large enough, do this in batches). Cook for about 5 to 7 minutes on one side, then turn over and cook for another 5 minutes or so. (Stuffed chicken breast should take a total of 10 to 12 minutes or until fully cooked through and international temperature of the chicken registers 165 degrees F).
- Garnish and Serve! Let the chicken rest for about 5 minutes. You can serve the whole breast or cut them into pieces. Garnish with the remaining walnuts and parsley.
Baked option
If you’d rather bake these stuffed chicken breasts instead, turn the oven on 350 degrees F. Arrange the chicken in a lightly oiled baking dish, and bake on the center rack of your heated oven for about 16 minutes or until the internal temperature of the chicken at the thickest part registers 165 degrees F.
How to serve it
Allow the chicken about 5 minutes to rest before serving.
From there, you can decide whether to serve each person their very own chicken breast (this is a very satisfying and generous portion). Or, you can slice each breast into smaller portions. This will show off the beautiful filling inside and will also allow you to serve more people (up to 6 people).
What to serve with it?
Here are some ideas for what you can serve with spinach stuffed chicken breast:
Sides: Roasted Greek Potatoes; Italian Roasted Vegetables; Or Grilled Zucchini
Salads: White Bean Salad; Blanched Asparagus with Mediterranean Salsa; or Traditional Greek Salad
Additional recipe FAQs
Start with larger boneless, skinless chicken breasts that give you enough “meat” to work with. Place the chicken breast flat on a clean cutting surface and use your non-dominant hand to firmly hold the chicken down. Then, using a sharp knife, simply cut horizontally through the middle, making sure to stop before fully splitting the chicken breast open. In other words, you’ll create a pocket to hold the filling.
I don’t typically seal my stuffed chicken breasts. But if you’re worried about losing filling to your skillet, just grab a few toothpicks! Simply poke the toothpicks through the opening of the filling pocket to close it.
Over medium-high heat, these chicken breasts will cook in about 10 minutes or so. You can also bake them in a 350 F heated oven for about 16 minutes or until the chicken temperature registers 165 degrees F.
Heat them on the stove over medium heat or in a medium-heated oven. It helps to add a little water and to cover your pan so that the chicken breasts will not dry out as they warm through. Avoid the microwave, which can tend to turn them dry and rubbery.

Easy Stuffed Chicken Breast Recipe
Ingredients
- 4 boneless skinless chicken breasts
- Kosher salt and black pepper
- Extra virgin olive oil,
- For the filling/stuffing
- ½ cup Ricotta cheese
- ¼ cup shredded mozzarella
- ¼ cup grated Parmesan
- ¾ cup walnut halves, finely chopped, divided
- 5 ounces frozen spinach thawed and drained (squeeze all the water out of the spinach
- 6 sundried tomatoes in olive oil chopped (more for garnish)
- ¼ cup chopped fresh parsley more for garnish
- 2 garlic cloves minced
- 1 teaspoon oregano
Instructions
- Make the filling. In a mixing bowl combine the ricotta cheese, mozzarella, Parmesan, chopped walnuts (save ¼ cup walnuts for later), spinach, sundried tomatoes, parsley, garlic and oregano. Add a pinch of kosher salt and black pepper. Drizzle with a little bit of extra virgin olive oil. Mix until well combined.
- Pat the chicken breast dry and season on both sides with Kosher salt and black pepper.
- Now, you need to make a pocket in each chicken breast. Lay a chicken breast flat on a cutting board. Place a hand firmly on top of the breast. Insert a good chef’s knife in the thickest part of the breast and cut through to make a pocket about 3 to 4 inches wide (only cut ¾ of the way in or you will split the chicken breast).
- Spoon the stuffing mixture into the pocket of each chicken breast (try to equally divide the stuffing among all four pieces).
- In a large cast iron skillet, heat 3 tablespoons extra virgin olive oil over medium-high heat until shimmering but not smoking. Add the chicken in and cook on one side for 5 to 7 minutes, then turn over and cook on the other side for another 5 minutes or so (chicken’s internal temperature should register 165 degrees F).
- Remove from heat and allow the chicken 3 to 5 minutes to rest. If you like, slice the chicken up into smaller pieces and garnish with the remaining walnuts, a bit of parsley and sundried tomatoes. Enjoy!

Notes
- To serve. If you leave the stuffed chicken breasts whole, you can serve 4 people (this is a very generous serving). But I like to slice up the chicken breasts, which shows off the beautiful stuffing and also allows me to serve more people (6).
- Baked option: You can bake this chicken in a lightly oiled baking dish at 350 degrees F heated for about 16 to 18 minutes or until the internal temperature at the thickest part of the chicken registers 165 degrees F.
- Sides to serve along: Garlic and Herb Boiled Potatoes; Roasted Greek Potatoes; Italian Roasted Vegetables; Or Grilled Zucchini

Could you use roasted tomatoes instead of sundried tomatoes? I am trying to use up the last of my tomatoes.
Sure!
This looked so delicious, I decided to try it. I was easy to make. Recipe is easy to follow. I substituted pine nuts for walnuts. And it worked great. I toasted them for 5 minutes in the oven first. The stuffing was great and I am thinking of other recipes I could use it in, like stuffed shells and stuff eggplant. Thanks so much. Your recipes never disappoint. I come back to them time and time again.
Thank you so much for sharing your experience, Michele!
I love chicken! This looks absolutely delicious I can’t wait to try it.
Thanks, Maria!
I;m ashamed to say I have never stuffed chicken breasts nor tried them but your recipe was so indepth and well presented that I’m convinced to try it.
I agree with you – walnuts are mostly used in baking but they are delicious in savory dishes. Love your recipe!
Chicken breast is one of my favorite part of chicken, and am always on the lookout for new recipes. This looks so so tasty and flavorful! I hope to give it a try.
I hope you do! You’ll love it!!!
I really love the stuffing and how you’ve served it.
Thanks, Jacqueline!
Very tasty filling! But a huge splattery mess to clean up after sauteeing, even with a splatter screen. And a very crusty and hard to clean cast iron pan. Has anyone tried baking the dish instead? I’m wondering how best to do that without drying them out.
I’m sorry about the mess, Ellen! I’m sure there is a way to bake them, but I have not tried that with this particular recipe yet, so it’s hard for be to advise. So glad you enjoyed them, though!
This looks amazing! The flavors are perfect and I love sun dried tomatoes. Thanks for this recipe!
I hope you give it a try, Chenee!
I don’t care for ricotta, so what would you suggest?
Thank you.
For this recipe, I would just omit the ricotta, and maybe add some more mozzarella.
Can you sub roasted red peppers for the sundried? Hubs is not a big fan!
Sure! The flavor profile will be a bit different, but still tasty!!
This is a fantastic recipe…I had to omit the walnuts because of allergies in my family…but still delicious, like all your recipes
Awww! Thank you, Sadia!
This looks delicious. And it is KETO friendly. I can’t wait to try it 🙂
Enjoy!!!
I prefer not to fry foods as much as possible. At what temp and for how long would you cook these chicken breasts in the oven? I’m thinking maybe 350* for about 30 – 35 minutes?
Pan-seared in extra virgin olive oil is a better choice for this recipe, but you can try baking at 350 degrees F, and the best way to know if it’s done is to use a meat thermometer (internal temperature should register at 165 degrees F).
The recipes are always great, but they NEVER include the oven temp.
Hi, Tom. This particular recipe is cooked on a stovetop, not the oven.
Now this filling for these chicken breast is loaded with everything I love! And I hav to agree with Steven, the walnuts are a special touch. We love walnuts around here, but I gotta start using them more in savory items too!
Totally, Amanda! We use walnuts here in savory cooking all the time. They add flavor and nutrition!
I just happened to pop on your site looking for a chicken breast recipe and this one is the winner! I love the addition of walnuts here, and thank you so much for sharing all this good information!!!
Awesome, Steven! Thanks for sharing
