Ingredients You Need

Chicken

4 boneless, skinless chicken breasts, medium size, about 6 to 7 ounces each
1 to 1½ teaspoons kosher salt
½ teaspoon black pepper
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon smoked paprika or sweet paprika

Spinach filling

1 tablespoon olive oil
2 cloves garlic, minced (jarred minced garlic works fine if you feel tired)
5 ounces fresh baby spinach, roughly chopped
- You can use frozen chopped spinach; squeeze it very dry in a clean towel.
4 ounces cream cheese, softened
- Use full fat for the creamiest filling; light cream cheese still works.
½ cup shredded mozzarella cheese
¼ cup grated Parmesan cheese
¼ teaspoon red pepper flakes, optional for a little heat
Pinch of salt and pepper, to taste

Coating and cooking

1 to 2 tablespoons olive oil
1 tablespoon butter, optional for extra browning and flavor

Cooking spray if you bake the chicken

Equipment

Sharp chef’s knife
Cutting board
Small skillet for the spinach
Mixing bowl
Spoon or spatula
Large oven safe skillet or baking dish
Instant read thermometer
Toothpicks

Quick Tips & substitutions

Pat the chicken dry before seasoning so the spices stick and the chicken browns better.
Slice a pocket in the thickest side of each breast and keep the knife parallel to the board so you do not slice through the top or bottom.
Use frozen spinach if you like; thaw it and squeeze out every bit of water so the filling stays thick and creamy.
Swap cream cheese with mascarpone or ricotta if you prefer a lighter filling; add extra Parmesan for more flavor.
Use shredded Italian blend cheese instead of mozzarella if that is what you have.
Season the outside of the chicken generously; the filling tastes rich, so the chicken needs bold seasoning too.
Secure the opening with toothpicks so the filling stays inside while the chicken cooks.
Bake at 400°F or sear on the stove first, then finish in the oven for the best color and texture.
Check the internal temperature at the thickest part and stop cooking when it reaches 165°F so the chicken stays juicy.
Rest the chicken for 5 minutes before slicing so the juices settle and the filling thickens slightly.

How to Make Spinach Stuffed Chicken Breasts Recipe

Step 1: Prep the chicken

Place the chicken breasts on a cutting board and pat them dry with paper towels. Season both sides with salt, pepper, garlic powder, onion powder, and paprika. Use your fingers to press the seasoning into the surface.

Hold a sharp knife along the thickest side of each breast and slice a deep pocket, leaving about a half inch uncut on the other side. Move the knife gently inside the chicken to widen the pocket without poking through the top or bottom.

Step 2: Make the spinach filling

Heat 1 tablespoon olive oil in a small skillet over medium heat. Add the minced garlic and stir for about 30 seconds until it smells fragrant. Add the chopped spinach and cook until it wilts and most of the moisture cooks off.

Transfer the spinach and garlic to a bowl and let it cool for a couple of minutes. Add the cream cheese, mozzarella, Parmesan, red pepper flakes, and a pinch of salt and pepper. Stir until the mixture looks smooth and thick, and taste it to adjust the seasoning.

Step 3: Stuff the chicken

Spoon the spinach mixture into each chicken pocket, dividing it evenly among the four breasts. Push the filling deep into the pocket so it sits in the center and does not spill out. Use toothpicks to close the opening with a few stitches across the cut side.

Press the outside of each stuffed chicken breast gently to shape it and keep the filling snug. Sprinkle a little extra paprika or black pepper on top if you want more color.

Step 4: Sear the chicken

Preheat your oven to 400°F. Heat a large oven safe skillet over medium high heat and add 1 to 2 tablespoons olive oil. When the oil shimmers, place the stuffed chicken breasts in the skillet with the smooth side down.

Sear each side for about 3 to 4 minutes until the chicken develops a golden crust. Add the butter to the skillet and tilt the pan to spoon the melted butter over the tops of the chicken for extra flavor.

Step 5: Finish in the oven

Transfer the skillet to the preheated oven. Bake for 12 to 18 minutes, depending on the thickness of the chicken, until the internal temperature reaches 165°F at the thickest part. Check at the 12 minute mark so you do not overcook it.

Remove the skillet from the oven and let the chicken rest for 5 minutes. Pull out the toothpicks carefully before serving. Spoon any pan juices over the chicken for extra flavor and shine.

Step 6: Optional baked only method

If you skip the stovetop sear, spray a baking dish with cooking spray and place the stuffed chicken breasts inside. Drizzle with olive oil and sprinkle a little extra paprika on top. Bake at 400°F for about 25 to 30 minutes, until the chicken hits 165°F.

Turn the broiler on for 2 to 3 minutes at the end if you want more color on top. Watch closely so the cheese and spices do not burn.

Storage Success

Let the spinach stuffed chicken breasts cool to room temperature, then store them in an airtight container in the fridge for up to 3 days. Reheat in a covered skillet over low heat or in the oven at 325°F so the chicken warms gently and stays juicy. You can freeze cooked stuffed chicken for up to 2 months; wrap each piece tightly and place them in a freezer bag. Thaw overnight in the fridge and reheat slowly so the filling stays creamy and the chicken keeps a tender texture.
