  • 4 large bell peppers (any color), halved and seeded
  • 1 cup sugar-free marinara sauce
  • 1 ½ cups shredded mozzarella cheese, divided
  • ½ cup mini pepperoni slices (or regular, cut into quarters)
  • ½ cup cooked Italian sausage, crumbled (optional, for extra protein)
  • ¼ cup grated Parmesan cheese
  • 1 tablespoon olive oil
  • 1 teaspoon dried Italian seasoning
  • ¼ teaspoon crushed red pepper flakes (optional)
  • Salt and black pepper, to taste
  • 2 tablespoons chopped fresh basil or parsley for garnish

Instructions

Prepare the oven and peppers
Preheat your oven to 400°F (200°C). Drizzle the bell pepper halves with olive oil and season lightly with salt and pepper. Arrange them cut-side up in a baking dish.
Mix the filling
In a bowl, combine the marinara sauce, 1 cup of the shredded mozzarella, cooked Italian sausage (if using), half the pepperoni, Italian seasoning, and red pepper flakes. Mix well.
Fill the peppers
Spoon the filling evenly into the pepper halves.
Add the toppings
Top each stuffed pepper with the remaining mozzarella, remaining pepperoni, and Parmesan cheese.
First bake
Cover the dish loosely with foil and bake for 20 minutes.
Final bake
Remove foil and bake an additional 10 minutes, or until the cheese is bubbly and golden and the peppers are tender.
Serve
Remove from the oven and let cool for 5 minutes. Garnish with fresh basil or parsley before serving.

Zusatztipps für die Zubereitung

For perfectly tender peppers that still hold their shape, look for ones with flat bottoms that will sit upright in your baking dish. If your peppers won't sit flat, you can slice a very thin piece off the bottom to create a stable base—just be careful not to cut through to the inside of the pepper.

Varianten und Anpassungen

These pizza-stuffed peppers are incredibly versatile. For a vegetarian version, omit the sausage and double the pepperoni or add sautéed mushrooms for extra flavor and texture. You can also swap the mozzarella for provolone or cheddar for a different flavor profile. If you enjoy spice, increase the red pepper flakes or add some chopped jalapeños to the filling. For a breakfast twist, try adding scrambled eggs to the filling mixture.

Serviervorschläge

Serve these keto pizza stuffed peppers with a crisp green salad dressed with olive oil and vinegar for a complete meal. They also pair wonderfully with roasted cauliflower or zucchini noodles tossed in olive oil and garlic. For family members who aren't following keto, a side of garlic bread can round out their meal while you enjoy this low-carb delight.
