Zusatztipps für die Zubereitung

To ensure the best results, use a sharp knife for clean cuts and always check the internal temperature with a meat thermometer to reach 165°F (74°C). Letting the chicken rest for 2–3 minutes after baking is essential to keep the juices from escaping.

Varianten und Anpassungen

For a vegetarian version, you can substitute the pepperoni with sliced mushrooms or olives. You can also enhance the flavor profile by adding fresh basil or dried Italian herbs. Most importantly, ensure your marinara sauce is sugar-free to remain keto-compliant.
