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.

We enjoyed this recipe! It had great flavor. I did add fresh Thyme. I liked using fresh spinach as someone suggested. I’m going to try to do it in the oven next time just to see if it more moist.
Very tasty! Reading some comments about the stuffing coming out I decided to take 3 toothpicks per breast and soak it in water for a couple of hours. After stuffing the breasts I then cut the toothpicks in half, and strategically placed them along the cut line through both sides then I took butches twine, and laced the seam up. Worked perfectly with no stuffing oozing out. I paired the chicken with a strawberry spinach salad. Excellent! I think I’m going to make more stuffing and use it as another reader suggested to stuff a pork chop! Yum!
Thanks, Linda!
I made this tonight for dinner and it was amazing! On a scale of 1-10, I would give it a 10 for flavor, 8 for ease of preparing and 10 for presentation. Simple ingredients that I had on hand except for the walnuts, so I substitueted pine nuts that I toasted and chopped. It did take a few minutes longer to cook that recipe called for but in my experience with cooking chicken, it was not hard to decipher when it was done and it only was a few extra minutes in the cast iron and then sitting in the pan of the heat for a few more minutes while I prepped and finished making a salad. As usual, all the recipes I have tried from here have been winners! Thank you!
Thank you so much, Peggy!
Is there a way to cook the chicken in my oven? Cooking then in a pan in my apartment creates too much smoke and didn’t cook the chicken all the way through.
Hi, Chris! I think that would work. I have never tried, so it’s hard for me to advise on details, but maybe try 375 degrees F until the chicken reaches an internal temp of 165 degrees F (probably 30-40 minutes, depending on your oven).
I love this recipe and have made it many times now. I’ve had times where the cooking process was painless, but more times where the exterior is over-charring combined with a raw interior while filling is oozing out all over the pan. I saw some other folks having this trouble as well. Regardless, though, I keep making it, so that tells you how good it tastes! I’ve learned to finish it off in the oven at 375 for maybe 6 to 10 minutes (generally just keeping an eye on it), with foil loosely tucked around each breast to keep the filling in. Flatting large breasts beforehand is a good idea, too. Hope this helps.
Thanks for sharing your tips, Grayson.
Put a lid in the pan and cook chicken for the first 3 minutes then turn chicken and cover for another 3 minutes. Take off lid and brown both sides of chicken 2-3 minutes each side.
I have chicken thighs. Is there a way to make this with them without the stuffing method?
Hi, Julia… I don’t think that would work very well here. The stuffing of the chicken in key to the recipe.
very good dish, be sure to cook this thoroughly. 7 mins per side were not enough for my thick cutlets. i’d recommend doing this on cast iron and doing some combination of stovetop and oven, not just stovetop. flavors were amazing as per usual
Thanks, James!
I tried this the other night. Taste wise-it was really good. But my chicken breasts were in no way fully cooked in the time you stated. They were large breasts and too thick to cook as quick as you said. I would recommend that you tell people that if the breasts are thick, to pound them down. It would also help with having more room for the filling which oozes out too much. I am trying the recipe tomorrow again and will pound the breasts to flatten them and see if that works better. The problem with cooking the breasts longer in a cast iron skillet is that they get charred and then get hard on the outside So thinner is better. I may also add mushrooms and a bit more spice to the mixture. Do you have any specific spice recommendations to kick it up a notch?
Hi, Linda! You could try some red pepper flakes to jazz it up.
Absolutely delicious!! With 2 small children, I am able to whip up the filling quickly and the chicken cooks in no time! My 2 year old eats it and my family enjoys it. Healthy, fast and so tasty. Thank you for a great home cooked chicken recipe!
So glad this is one the whole family loves! Thanks, Dee Dee!
Can you bake this instead?
Hi, Colleen! 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.
This is one of the most delicious dishes I have ever made, and I consider myself a pretty good home cook! I made it over a month ago and we’re still talking about it. I made my own ricotta (super easy – highly recommended and way better than storebought). I also used fresh spinach, which I wilted first, instead of frozen. The flavor was unforgettable 🙂 I served it with Suzy’s roasted cauliflower, which was also delicious.
So glad you enjoyed the recipe, Jen!
can i use fresh spinach?
Sure!
Excellent — Yummy — perfect! I doubled the filling and used it a few days later to stuff a pork tenderloin. YUMMMMMM — so good!!!
Great idea!
I recently needed to make big changes in my eating habits and I decided to try the Mediterranean diet, but I didn’t know where to start. I discovered your website this week and I’ve spent hours every day drooling over your recipes. I did a major shopping trip today and loaded up on ingredients. We had the stuffed chicken (the filling is to die for) and the roasted Italian veggies for dinner tonight and they were both FANTASTIC!! I can hardly wait for the leftovers to be eaten so I can keep working my way down my list. Thank you so much, especially for the videos, which I LOVE.
