Instructions

In a medium bowl, combine 1 cup mozzarella, Parmesan, egg, onion powder, garlic powder, and Italian seasoning. Mix until well blended.
Slice a pocket into the side of each chicken breast (do not cut all the way through).
Divide cheese mixture evenly among chicken breasts, stuffing ¼ into each pocket.
Place stuffed chicken breasts in a 6-quart slow cooker. Top each with sliced green pepper.
Pour marinara sauce evenly over the chicken.
Sprinkle remaining 1 cup mozzarella on top, then arrange pepperoni slices over the cheese.
Cover and cook on HIGH for 2½–3 hours or LOW for 4–5 hours, until chicken reaches 165°F and is tender.
Serve as-is or over pasta, rice, or zucchini noodles.

Notes

– Use freshly shredded mozzarella for better melting and creamier texture.

– Don’t overstuff the chicken—excess filling may leak out during cooking.

– Gluten-free: Naturally GF; just verify marinara and pepperoni labels if needed.

– Low-carb: Skip pasta and serve over zucchini noodles or cauliflower rice.

– Vegan option: Use plant-based chicken, flax egg (1 tbsp ground flax + 2.5 tbsp water), dairy-free cheese, and vegan pepperoni.

– Storage: Keeps in the fridge for up to 3 days or freezes well for up to 3 months. Reheat with a splash of marinara to retain moisture.
