Why You’ll Love This Recipe

I love this recipe because I get the familiar flavors of pizza in a protein-packed main dish. The combination of mozzarella, tomato sauce, Italian seasoning, and pepperoni gives me plenty of classic pizza flavor without needing to prepare pizza dough.

I also appreciate that the oven does most of the cooking. Once I stuff and season the chicken, I arrange everything in a baking dish and let it cook until the chicken is tender and the cheese is melted.

Another reason I enjoy this recipe is how customizable it is. I can change the cheese, leave out the pepperoni, add vegetables, or experiment with different pizza-inspired fillings.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Boneless, skinless chicken breasts
Mozzarella cheese, sliced or shredded
Pizza sauce or marinara sauce
Pepperoni slices
Olive oil
Italian seasoning
Garlic powder
Onion powder
Smoked paprika
Salt
Black pepper
Grated Parmesan cheese
Fresh basil or parsley, optional
Red pepper flakes, optional

Directions

I preheat my oven to 400°F (200°C) and lightly grease a baking dish.
I pat the chicken breasts dry with paper towels. Using a sharp knife, I carefully cut a pocket into the side of each chicken breast without slicing completely through it.
I season the chicken on both sides and inside the pockets with salt, black pepper, garlic powder, onion powder, Italian seasoning, and smoked paprika.
I fill each chicken breast with mozzarella and several pepperoni slices. I avoid overfilling the pockets so I can keep most of the cheese inside while the chicken bakes.
When necessary, I secure the openings with toothpicks to help keep the filling in place.
I arrange the stuffed chicken breasts in the prepared baking dish and brush the tops lightly with olive oil.
I spoon pizza sauce or marinara over each chicken breast.
I sprinkle additional mozzarella and Parmesan over the sauce. I add a few extra pepperoni slices on top when I want even more pizza flavor.
I bake the chicken for approximately 25–35 minutes, depending on the thickness of the breasts. I make sure the thickest part of the chicken reaches an internal temperature of 165°F (74°C).
If I want more browning on the cheese, I place the chicken briefly under the broiler at the end, watching it carefully so the cheese doesn’t burn.
I remove the chicken from the oven and let it rest for about 5 minutes.
I finish with chopped fresh basil or parsley and optional red pepper flakes before serving.

Variations

When I want a vegetable pizza version, I replace the pepperoni with sautéed mushrooms, bell peppers, spinach, or onions. I cook vegetables with a high water content before stuffing the chicken so they don’t release too much moisture while baking.

For extra cheese, I combine mozzarella with provolone, Parmesan, or ricotta. I particularly like provolone when I want a stronger, slightly sharper cheese flavor.

When I want some heat, I add sliced jalapeños, crushed red pepper flakes, or spicy pepperoni. I can also stir a little chili into the pizza sauce.

For a different pizza-inspired combination, I use cooked sausage with mozzarella or add olives and sautéed peppers. I keep the filling relatively compact so the chicken remains easy to close.

I can also leave out the meat filling entirely and make a simple mozzarella-stuffed version with tomato sauce, basil, and Parmesan.

Storage/Reheating

I let leftover Baked Pizza Mozzarella Stuffed Chicken cool before placing it in an airtight container. I store it in the refrigerator for up to 3–4 days.

For reheating, I prefer placing the chicken in a covered baking dish and warming it in the oven until thoroughly heated. I add a spoonful of extra pizza sauce when needed to help keep the chicken moist.

For a faster option, I microwave individual portions in short intervals. I cover the chicken loosely while reheating to help prevent it from drying out.

I can freeze the cooked stuffed chicken in a freezer-safe container, although I find that freshly baked chicken gives me the best texture. I thaw frozen portions in the refrigerator before reheating them thoroughly.

FAQs

How do I keep the mozzarella inside the stuffed chicken?

I cut a deep pocket without slicing all the way through the chicken and avoid adding too much filling. I also place the cheese toward the center of the pocket and secure the opening with toothpicks when necessary. Some melted cheese may still escape, and I simply spoon it back over the chicken when serving.

Can I make Baked Pizza Mozzarella Stuffed Chicken without pepperoni?

Yes. I can leave the pepperoni out completely or replace it with cooked sausage, mushrooms, spinach, bell peppers, or another pizza topping I enjoy. A simple mozzarella, tomato, and basil filling also works well.

How do I know when stuffed chicken is fully cooked?

I use an instant-read thermometer and check the thickest part of the chicken rather than relying only on its appearance. I cook the chicken until it reaches an internal temperature of 165°F (74°C).

Can I prepare this stuffed chicken ahead of time?

Yes. I can prepare and stuff the chicken in advance, cover it tightly, and refrigerate it until I am ready to bake. I prefer adding the final layer of sauce and cheese shortly before it goes into the oven.

What can I serve with Pizza Mozzarella Stuffed Chicken?

I like serving this chicken with roasted vegetables, garlic bread, a green salad, steamed broccoli, or pasta. When I want a particularly simple meal, I pair it with a crisp salad because the stuffed chicken is already rich and satisfying.

Conclusion

This Baked Pizza Mozzarella Stuffed Chicken gives me a fun way to enjoy pizza-inspired flavors in a hearty baked dinner. The combination of juicy chicken, melted mozzarella, savory tomato sauce, pepperoni, and Italian seasonings makes every serving rich, cheesy, and satisfying.

Notes

For a vegetable pizza variation, replace the pepperoni with sautéed mushrooms, bell peppers, spinach, or onions. Cook high-moisture vegetables before stuffing the chicken.
Provolone, ricotta, or additional Parmesan can be combined with the mozzarella for a different cheese flavor.
Add sliced jalapeños, crushed red pepper flakes, spicy pepperoni, or chili to the sauce for extra heat.
Cooked sausage, olives, or sautéed peppers can be used for other pizza-inspired filling combinations.
For a meatless filling, omit the pepperoni and stuff the chicken with mozzarella, tomato sauce, basil, and Parmesan.
The chicken can be stuffed ahead, covered, and refrigerated until ready to bake. Add the final sauce and cheese shortly before baking.
Store leftovers in an airtight container in the refrigerator for 3–4 days. Reheat covered in the oven with a spoonful of extra pizza sauce to help keep the chicken moist.
Cooked stuffed chicken can be frozen in a freezer-safe container. Thaw overnight in the refrigerator before reheating thoroughly.
