Ingredients Method

Ingredients
  

  • 2 to 2.5 pounds boneless, skinless chicken breasts (or thighs)
  • 1 cup low-carb marinara sauce (look for 4g net carbs or less per 1/2 cup)
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon dried Italian seasoning (or a mix of oregano and basil)
  • 1/2 teaspoon crushed red pepper flakes (optional, for heat)
  • Salt and black pepper, to taste
  • 1 cup shredded mozzarella cheese
  • 1/4 cup grated Parmesan cheese
  • 20–30 slices of pepperoni (sugar-free if possible)
  • 1/2 cup sliced mushrooms (optional)
  • 1/4 cup sliced black olives (optional)
  • 1/2 small green bell pepper, thinly sliced (optional)
  • 2 tablespoons olive oil (optional, for extra richness)
  • Fresh basil or parsley, chopped, for garnish

Method
 

  1. Prep the chicken: Pat the chicken dry and season on both sides with salt, pepper, garlic powder, onion powder, and Italian seasoning. If using thighs, trim excess fat. Keep pieces in a single layer if possible.
  2. Add sauce to the crockpot: Pour half the marinara into the slow cooker and spread it out. Drizzle in the olive oil if you like a richer sauce.
  3. Layer the chicken: Place the seasoned chicken over the sauce. Spoon the remaining marinara over the top so the chicken is lightly coated but not swimming in sauce.
  4. Slow cook: Cover and cook on Low for 4–5 hours or on High for 2–3 hours, until the chicken reaches 165°F and is tender. Avoid overcooking to keep it juicy.
  5. Add toppings: Sprinkle mozzarella and Parmesan over the chicken. Top with pepperoni, mushrooms, olives, and bell pepper. Add a pinch of red pepper flakes if you like heat.
  6. Melt and finish: Cover and cook for another 15–20 minutes on Low, until the cheese is melted and bubbly. If your slow cooker insert is oven-safe, you can broil for 2–3 minutes for a browned top.
  7. Rest and serve: Let it sit for 5 minutes, then garnish with fresh basil or parsley. Serve with zucchini noodles, a green salad, or roasted broccoli.
