This spinach stuffed chicken breast recipe combines three cheeses, walnuts, sun-dried tomatoes, and spinach to give you big Mediterranean flavor in just 20 minutes!
Chicken Breast Recipe Bursting with Mediterranean Flavors
Chicken breast gets a bad rap for being boring, but I like to think of it as a blank canvas for some of my favorite Mediterranean flavors. They just need a delicious filling to wow even the most skeptical diner. When it comes to flavor, those of us with Mediterranean heritage know a thing or two about combining bold flavors for maximum impact!
With bright sun-dried tomatoes, creamy ricotta cheese, and aromatic oregano, they this chicken breast recipe has Italian-style comfort but it isn’t overly heavy. And, because stuffed chicken breast cooks quickly in one skillet, this easy dinner recipe is 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 ever!
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. Sauté 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 sun dried tomatoes. 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 lean 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.
- A vegetable salad: Fattoush or Greek Salad
- Grain or starch: Basmati Rice or Quinoa Salad
- For dessert: I like a little pop of citrus to balance the richness of the cheesy filling. Lemon tart or lemon sorbet both come to mind, but if lemon isn’t your thing, try Greek Yogurt Cheesecake.

Frequently Asked Questions
It’s best to use thick chicken breast. Press you non-dominate hand on the top of the chicken breast and with the knife in your other hand, slowly make a horizontal in the center of the chicken breast without cutting all the way through the back. Widen the cut from one side to the other until you have a wide, pocket.
Some filling will likely fall out, but you can reduce the likelihood of that by following a couple of guidelines. First, don’t overstuff the pocket. Second, let the chicken rest for a few minutes before slicing. This gives the filling a chance to cool slightly and become less runny.
Yes, you can prepare the chicken and make the filling up to 1 day in advance, keeping them in separate containers. Then the day you want to serve them stuff and cook.
Yes—chicken breast is considered a lean protein, and the spinach-feta-walnut filling adds iron, calcium, and healthy fats. My recipe doesn’t have breading or heavy cream.
Very flavorful and easy to make. I add baby potatoes and bake the entire meal in one pan in the oven.
Excellent. Good flavor. Had to cook the chicken longer, but not a problem.
Fast and delicious! Don’t skip on the walnuts.
Love this stuffed chicken recipe. In fact everyone in the family loves it, and that is rare! Easy to prepare and cook, and I’ve never messed it up. As a new cook, this is a biggie for me. Recommend it highly!
Perfect balance of flavors. I made the filling ahead of time. I’m going to make extra to freeze next time.
