Stuffed Chicken Breast Recipe

Overview

This stuffed chicken breast recipe pairs lean chicken with a creamy filling of spinach, garlic, cream cheese, and mozzarella. Searing the chicken first adds color and flavor, while a short finish in the oven cooks the thick breasts evenly.

The key is to cut a deep pocket without slicing all the way through and to use an instant-read thermometer rather than relying on appearance alone. The chicken is ready when the thickest part reaches 165°F (74°C), and the filling is hot and lightly melted.

Ingredients

• 4 boneless, skinless chicken breasts, about 8 ounces (225 g) each
• 1 tablespoon olive oil, plus more for brushing if needed
• 5 ounces (142 g) fresh baby spinach
• 2 garlic cloves, finely minced
• 4 ounces (113 g) cream cheese, softened
• 1/2 cup (56 g) shredded low-moisture mozzarella
• 1/4 cup (20 g) finely grated Parmesan cheese
• 1/2 teaspoon kosher salt, plus more for the filling
• 1/2 teaspoon freshly ground black pepper
• 1/2 teaspoon Italian seasoning
• 1/4 teaspoon red pepper flakes, optional
• 1 tablespoon chopped fresh parsley, optional

How to make it

1. Heat the oven and prepare the filling. Heat the oven to 400°F (200°C). Warm a large ovenproof skillet over medium heat. Add the spinach and cook for 1 to 2 minutes, turning often, until wilted. Transfer it to a plate, let it cool briefly, then squeeze out as much liquid as possible and chop it. Excess moisture can make the filling run out during cooking.

2. Mix the filling. In a bowl, stir together the softened cream cheese, mozzarella, Parmesan, chopped spinach, garlic, 1/4 teaspoon of the salt, 1/4 teaspoon of the black pepper, Italian seasoning, red pepper flakes if using, and parsley. The mixture should be thick enough to mound on a spoon. If the cream cheese is firm, microwave it for 10 seconds at a time until spreadable, but do not heat it until warm.

3. Cut pockets in the chicken. Pat the chicken breasts dry with paper towels. Place one breast smooth-side down on a cutting board. Holding a sharp knife parallel to the board, cut into the thickest side to create a pocket, stopping about 1/2 inch from the opposite edge. Do not cut through the breast. Repeat with the remaining chicken. Season the outside on all sides with the remaining salt and pepper.

4. Fill and secure the breasts. Divide the filling into four portions. Spoon it into the pockets, leaving a little room around the opening so the filling does not immediately squeeze out. Press the cut edges together and secure each breast with two or three toothpicks if needed. Insert the toothpicks crosswise and remember to remove them before serving.

5. Sear the chicken. Heat the olive oil in the ovenproof skillet over medium-high heat until it shimmers. Add the stuffed chicken and cook for 2 to 3 minutes on the first side, without moving it, until golden brown. Turn and sear the second side for 2 minutes. If the pan is crowded, work in batches or use a second skillet; crowded chicken will steam instead of brown.

6. Finish in the oven. Transfer the skillet to the oven and bake for 15 to 22 minutes, depending on the thickness of the breasts. Start checking at 15 minutes. The chicken is done when an instant-read thermometer inserted into the thickest chicken portion, avoiding the filling and bone, reads 165°F (74°C). The juices should run clear, the center should feel firm but springy, and the cheese filling should be hot and soft.

7. Rest and serve. Transfer the chicken to a plate and rest for 5 minutes. This gives the filling time to settle and makes slicing cleaner. Remove all toothpicks, then slice each breast into thick pieces or serve whole with the pan juices.

Expert tips

• Use evenly sized breasts. Very thick chicken takes longer to cook, while thin pieces can dry out before the filling is hot. Pound unusually thick areas gently to create a more even shape before cutting the pocket.
• Keep the filling contained. Do not overfill the pockets. If some filling escapes during searing, lower the heat slightly and continue; a little melted cheese is normal, but a large opening can leave the chicken dry.
• Spinach substitutions: Use 3 ounces (85 g) frozen chopped spinach, thawed and squeezed very dry, instead of fresh spinach. Chopped kale also works, but cook it for several minutes until tender before mixing.
• Cheese substitutions: Replace mozzarella with Monterey Jack, provolone, or fontina. For a sharper filling, use an equal amount of crumbled feta in place of the Parmesan, though the mixture will be saltier.
• If the chicken browns too quickly, reduce the stovetop heat before transferring the skillet to the oven. If the breasts are cooked but the filling is still cool, cover the skillet loosely with foil and bake for a few more minutes, checking the chicken temperature again.
• If you do not have an ovenproof skillet, sear the chicken in a regular skillet, then transfer it to a lightly oiled baking dish for the oven.

Serving and storage

Serve the chicken with roasted vegetables, a green salad, rice, or crisp potato wedges. For another chicken dinner with a pan sauce, see this creamy chicken mushroom skillet recipe. Baked potato wedges are also a practical side for the cheesy filling.

Cool leftovers promptly and refrigerate them in a covered container within 2 hours. Store for up to 3 to 4 days. Reheat gently in a covered skillet with a tablespoon of water, or in a 350°F (175°C) oven until the center reaches 165°F (74°C). Cut leftovers into slices before reheating if you want them to warm more evenly.

Frequently asked questions

How do I keep stuffed chicken breast from opening while it cooks?

Cut the pocket carefully without slicing through the opposite side, avoid overfilling it, and secure the opening with toothpicks if necessary. Sear the cut side gently and turn the chicken with tongs rather than a fork.

Can I prepare stuffed chicken breast ahead of time?

Yes. Assemble and refrigerate the uncooked stuffed breasts in a covered container for up to 24 hours. Keep them cold until cooking, then add a few extra minutes to the oven time if needed and verify that the thickest chicken reaches 165°F (74°C).

Why is my stuffed chicken breast dry?

The most common causes are overcooking, unevenly thick breasts, or cutting into the chicken immediately after baking. Check the temperature early, use similarly sized breasts, and rest the chicken for 5 minutes before serving.

Can I use frozen spinach in the filling?

Yes. Thaw about 3 ounces (85 g) of frozen chopped spinach, squeeze it very dry, and chop it before mixing. Removing excess water keeps the filling thick and reduces the chance of it leaking out.
