Pepperoni pizza stuffed chicken is the weeknight dinner that completely changed how my family does pizza night. This recipe tucks all the bold, cheesy, saucy flavors of a classic pepperoni pizza right inside juicy butterflied chicken breasts – no dough required and no compromise on taste.

I still remember the first time I made this on a busy Tuesday with chicken in the fridge and serious pizza cravings. I butterflied those breasts, layered in thick mozzarella and pepperoni, spooned marinara over the top, and the whole family gathered around the oven watching the cheese bubble and turn golden. Now it is the most-requested dinner in my house. This pepperoni pizza stuffed chicken is low-carb, high-protein, and on the table in just 40 minutes – making it one of the best easy chicken dinner ideas for busy families.

What You Will Need to Make This Pepperoni Pizza Stuffed Chicken

I always grab a block of mozzarella instead of a pre-shredded bag for this recipe. Slicing it thick for the stuffing and shredding fresh for the topping gives you that incredible gooey melt that makes this dish truly special. Pro tip: medium-to-large chicken breasts with real thickness are essential here – thin cutlets do not have enough depth to hold all the filling.

• 4 boneless, skinless chicken breasts (medium-to-large with some thickness for stuffing)
• 1/2 tablespoon olive oil
• 1/2 teaspoon kosher salt
• 1/2 teaspoon ground black pepper
• 2 teaspoons garlic powder
• 2 teaspoons Italian seasoning (plus more for topping if desired)
• 24 oz marinara sauce (1 jar – your favorite brand or pizza sauce works great)
• 4 slices thick-cut mozzarella cheese (cut from a block for best melt)
• 30 slices pepperoni, divided (20 for stuffing, 10 for topping)
• 1 cup freshly shredded mozzarella cheese
• 1/8 cup freshly grated Parmesan cheese, divided

You will also need a 9×13-inch baking dish, nonstick cooking spray, a small mixing bowl, toothpicks, a sharp knife, and an instant-read meat thermometer.

How to Make Pepperoni Pizza Stuffed Chicken Step by Step

I recommend reading through all the steps before you start – the butterflying technique is simple once you know what you are looking for, and a little prep upfront makes everything come together smoothly. Here is exactly how to make this pepperoni pizza stuffed chicken from start to finish in 40 minutes.

Step 1: Preheat your oven to 400 degrees F. Spray a large 9×13-inch baking dish generously with nonstick cooking spray and set aside.

Step 2: In a small bowl, whisk together the olive oil, salt, pepper, garlic powder, and Italian seasoning until fully combined into a smooth seasoning mixture.

Step 3: Butterfly each chicken breast by using a sharp knife to cut horizontally about two-thirds of the way through each breast. Do not cut all the way through – the breast should open flat like a book and stay attached along one side. This is the most important step. Cutting all the way through causes the filling to spill out during baking.

Step 4: Rub the seasoning mixture evenly over all 4 chicken breasts, coating both the outside and the inside surfaces thoroughly.

Step 5: Open each butterflied breast flat. Place one thick slice of mozzarella inside, then layer with 5 pepperoni slices. Add a generous spoonful of marinara sauce and a light sprinkle of grated Parmesan. The layering order matters – cheese first creates a barrier that keeps the sauce from making the chicken soggy.

Step 6: Fold each chicken breast closed over the filling. Secure with toothpicks to hold everything in place during baking. Set a reminder to remove all toothpicks before serving.

Step 7: Pour half the marinara sauce into the bottom of the prepared baking dish and spread into an even layer. This creates a flavorful base that keeps the chicken moist throughout baking.

Step 8: Arrange all 4 stuffed chicken breasts in the dish directly on top of the marinara layer.

Step 9: Spoon the remaining marinara evenly over the top of each chicken breast, ensuring full coverage.

Step 10: Top generously with the shredded mozzarella, remaining 10 pepperoni slices, remaining Parmesan, and an extra pinch of Italian seasoning if desired.

Step 11: Bake uncovered for 25 minutes, or until the internal temperature of the thickest chicken breast reaches 165 degrees F on an instant-read thermometer, the cheese is melted and golden, and the sauce is actively bubbling around the edges. Bake time may vary slightly depending on the thickness of the breasts – always confirm with a thermometer. For crispier pepperoni on top, broil for the final 2 to 3 minutes and watch closely.

Step 12: Remove all toothpicks carefully before plating. Serve immediately while the cheese is hot and bubbly.

How to Store and Reheat Leftover Pizza Stuffed Chicken

Leftovers keep beautifully and taste just as satisfying the next day. Store leftover pepperoni pizza stuffed chicken in an airtight container in the refrigerator for up to 3 days. For longer storage, transfer to a freezer-safe container and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.

To reheat, warm covered in a 350 degree F oven for 15 to 20 minutes until heated through. The oven method keeps the cheese from getting rubbery and prevents the sauce from drying out. Microwave reheating works too – heat in 60-second intervals and add a spoonful of fresh marinara if the sauce looks dry.

Pro tip: this recipe is excellent for make-ahead prep. Assemble completely through Step 10, cover tightly with plastic wrap, and refrigerate for up to 24 hours before baking. Let it sit at room temperature while the oven preheats, then bake as directed for a completely stress-free dinner.
