This easy stuffed chicken breast recipe is the perfect mix of comforting and light. Three cheeses, walnuts, sun-dried tomatoes, and spinach gives you big flavor in just 20 minutes!
Chicken breasts get a bad rap for being boring, but I like to think of them as a blank canvas for flavor. They’re just missing a delicious filling! This stuffed chicken breast recipe proves just how delicious weeknight chicken can be.
With bright sun dried tomatoes, creamy ricotta cheese, and aromatic oregano, they have Italian-style comfort but aren’t overly heavy. And, because they cook quickly in one skillet, this easy recipe perfect for busy weeknights.
It also feels like a special night in without the fuss. As Lisa said in the comments: “This was delicious! My daughter said “mom, this is restaurant good!” I would have to agree! It was easy too!” Best compliment!

Ingredients and Substitutions
I wanted this spinach stuffed chicken breast recipe to be very much a “grab on the way home from work” situation. You’ll likely have most of what you need:
- Chicken breasts: You can also use chicken thighs and adjust the cooking time. Or you can even make spinach stuffed salmon.
- Frozen spinach: Already wilted and shrunk, it’s the secret to adding plenty of this superfood with almost no effort.
- Swapping fresh for frozen spinach: Start with about 1 pound of fresh spinach. Saute or blanch it until it’s wilted (it will shrink quite a lot), then allow it to cool before pressing or squeezing out the excess moisture.
- Walnuts: Substitute with another very tender nut, like pine nuts or almonds.
- Sun dried tomatoes: I prefer the rich flavor of unsulfered. Swap with green olives or chopped preserved lemons.
- Parsley: Substitute with dill, basil, or mint.
- Garlic: Swap with green onion, shallot, or yellow onion.
- Cheese: A 3-cheese mixture of ricotta, mozzarella, and parmesan is rich and flavorful without being heavy.
- Oregano: Look for Greek oregano, which is earthy and peppery, rather than Mexican oregano which is anise-like. Substitute with dried thyme, rosemary, or Italian seasoning.
- Kosher salt and black pepper enhance the flavor.
- Extra virgin olive oil holds the filling together and adds richness. I love our buttery Italian Nocellara with this recipe.
- Chicken breasts are lean and thick, making them perfect for stuffing.
How to Make Spinach Stuffed Chicken Breast
Using frozen spinach is the key to getting spinach stuffed chicken breasts on your table in under 30 minutes. Here are the steps:
- Drain the spinach. Place 5 ounces of thawed frozen spinach into a clean (but not precious) kitchen towel and twist to remove the excess water.
- Make the stuffing. Add the spinach to a medium mixing bowl along with 1/2 cup of chopped walnuts, 6 chopped sun dried tomatoes, 1/4 cup chopped parsley, 2 minced garlic cloves, 1/2 cup ricotta, 1/4 cup shredded mozzarella, 1/4 cup grated parmesan, and 1 teaspoon dried oregano. Season with a pinch of salt and pepper, drizzle with a little olive oil, and mix until well combined.
- Prep the chicken. Pat the chicken breasts dry and season on both sides with salt and 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 slice to make a pocket about 3- to 4-inches wide (only cut 3/4 of the way in or you will split the chicken breast).
- Stuff the chicken breasts. Spoon the stuffing mixture into the pocket of each chicken breast (try to equally divide the stuffing among all four pieces).
- Sear the chicken. In a large cast iron skillet, heat 3 tablespoons 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°F).
- Finish and serve. Remove from heat and allow the chicken 3 to 5 minutes to rest. If you like, slice the chicken into smaller pieces. Garnish with the remaining walnuts, a bit of parsley and sun dried tomatoes. Enjoy!
What to Serve with Spinach Stuffed Chicken Breast
Because chicken breasts are a leaner meat, I like to turn them into a satisfying yet healthy meal with:
- A hearty salad: Italian potato salad or Mediterranean orzo salad would be lovely.
- To finish: I like a little pop of citrus to balance the richness of the cheesy filling. Lemon tart or lemon sorbet both come to mind.

Another delish recipe that I make on repeat now in our house. I disagree about how quickly this comes together (maybe if your ingredients are all pulled and chopped it’s that fast), but if you aren’t worried about it being “20 minutes” it’s wonderful.
Fabulous dish and easy to follow recipe. I did finish it in the oven as the chicken breasts were quite thick.
Can’t eat cheese, what can I substitute in place of it?
I followed directions to the T! This was delicious! My daughter said “mom, this is restaurant good!” I would have to agree! It was easy too! I forgot to garnish the pieces at the end though…..
Yessss! What a huge compliment! Thank you!
This recipe was very good. It cooked beautifully in my skillet, perfect brown color. I was a little nervous it wasn’t going to be cooked through because of previous comments. I checked the temperature and it wasn’t at 165, but the juice in the plate it was on looked done but I still cooked it at 350 in 6 minutes in my oven. It seemed a little dry but my husband said it was really good and I thought the flavor was great too. I will make it again. Thank you for all the great recipes.
So glad you enjoyed this one, Sandra!
trying to eat better
Came out perfect as I baked in the oven ! I did not have walnuts so used 2-4 almonds when wizzing up the filling with the spinach, mozzarella etc, also used a dollop of Philadelphia ( had no ricotta) . Suzie I follow so many of your recipes and you are a queen of tasty Mediterranean dishes! I know when I go to your recipes it will be tasty , healthy and amazing! Thanks my dear 🩷
You are so sweet, Emma! Thank you!
Like everything I have tried from the cookbook and the site, this recipe was greatly enjoyed by my family. I used homemade mozzarella and ricotta, and subbed the parm for feta. Very easy, very tasty. I’ve made similar in the past but this was hands down the winner. The walnuts really make a difference too!
Thank you for the kind review, Ash!!
Hi Suzy
This looks like a great recipe but I think I missed something. In the picture you feature showing the skillet and the breasts cooking, I also see what looks like parsley, and other ingredients that you haven’t mentioned. Can you tell us what else you added to the cooking pan and the oil when you cooked these breasts?
Also, in the past when I have cooked stuffed chicken breasts, the directions always always warned the cook to use only about 1 and1/2 tablespoons of stuffing per breast. The stuffing expands as it is heated and perhaps this is why so many people commented on having their stuffing escaping from the breasts. I know my tendency is to want to put as much of the good stuffing into the breast as possible, but I learned from experience not to over-stuff them. Hope this helps some readers. And hope you can tell us what was added to the cooking pan other than olive oil.Many thanks!Sue H.
Hi, Sue. The ingredients you are seeing in the cast iron skillet at the end of cooking the garnishes of the remaining walnuts, a bit of parsley and sundried tomatoes mentioned in the last step of the instructions. Hope you give this recipe a try!
No flavor. Took 3 times as long to cook as depicted. Sorry, didn’t do it for me.
This was so good and easy to prepare
I sliced each breast in half or third. Seasoned as called for. Spread the filling on each piece of breast. Then I rolled each one & used toothpicks to hold them together. Brown them in cast iron pan the finished them in oven. I lost a lot of melted filling the other way.
Love the flavor of filling!!
Can’t honestly understand the times. 5-7mins each side? Was raw all the way through. More like 12 each side.
Good recipe! Thank you!
So, can you just spread the “stuffing” on top? Hubs prefers the thin breast cutlets.
This 20 minute stuffed chicken breast recipe is out of this world! It was absolutely delicious! I followed the recipe and it came out perfect! For just the two of us, I halved all the ingredients. It was a lot for one sitting, so we had the other half of each breast the next night and it was wonderful just reheated accompanied by a nice tossed spring salad! Thank you for such a fun and easy recipe! Loved it!
My pleasure, Debbie! Glad you enjoyed it!
