  • 4 large boneless, skinless chicken breasts
  • 3/4 cup shredded mozzarella cheese
  • 1/4 cup sliced pepperoni (about 16 slices)
  • 1/2 cup sugar-free marinara sauce
  • 1/4 cup grated Parmesan cheese

Instructions

1. Oven Prep
Preheat your oven to 400°F (200°C).
2. Cut the Pocket
Using a sharp knife, carefully cut a deep pocket into each chicken breast, being careful not to slice all the way through.
3. Stuff the Chicken
Spoon about 1 tablespoon marinara sauce into each pocket, followed by a layer of shredded mozzarella and a few slices of pepperoni. Reserve remaining sauce and cheese for topping.
4. Secure
Secure the edges of the chicken breasts with toothpicks if necessary.
5. Sear
Heat a large oven-safe skillet over medium-high heat. Lightly grease with oil if desired. Sear the stuffed chicken breasts for 2–3 minutes per side, until golden brown.
6. Top and Bake
Spoon remaining marinara sauce over the chicken, sprinkle with leftover mozzarella and all the Parmesan. Transfer the skillet to the preheated oven and bake for 15–18 minutes, or until the chicken is cooked through (internal temperature 165°F/74°C).
7. Rest and Serve
Remove toothpicks, let rest for 2–3 minutes, and serve hot.

Zusatztipps für die Zubereitung

Ensure you use a sharp knife to create the pocket to keep the chicken intact. To keep this recipe strictly keto, always verify that your marinara sauce contains no added sugars. If you don't have an oven-safe skillet, you can transfer the seared chicken to a baking dish before topping and putting it in the oven.
