Instructions

Step 1
Preheat your oven to 400°F (200°C).
Step 2
Using a sharp knife, carefully cut a deep pocket into each chicken breast, being careful not to slice all the way through.

Step 9
Remove toothpicks, let rest for 2–3 minutes, and serve hot.

Recipe FAQs

How do I prevent the filling from leaking during cooking?

Carefully cut a deep pocket in the chicken breasts without piercing through and secure edges with toothpicks if needed to keep fillings inside while cooking.

Can I use regular marinara sauce instead of sugar-free?

Yes, but sugar-free marinara keeps the dish low-carb. Regular sauce may add extra sugars, affecting keto-friendly status.

What’s the best way to cook these stuffed chicken breasts?

Sear them in a hot oven-safe skillet to brown the outside, then finish baking in the oven for even cooking and melted cheese.

Are there vegetarian alternatives for the pepperoni?

Sliced mushrooms or olives make excellent vegetarian substitutes that keep the savory flavor of the filling.

How can I ensure the chicken stays juicy?

Don’t overcook; bake until internal temperature reaches 165°F (74°C), and let rest a few minutes before serving to retain juices.
