Zusatztipps für die Zubereitung

When selecting bell peppers, look for ones with flat bottoms that will stand upright in your baking dish. For a speedier version, you can pre-cook the peppers in the microwave for 2-3 minutes before stuffing them. This reduces the overall baking time by about 10 minutes and ensures your peppers will be perfectly tender.

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. Create a 'supreme' version by adding diced onions, green peppers, and black olives to the filling. For a different flavor profile, try using provolone or cheddar instead of mozzarella, or add a few tablespoons of ricotta for a creamier texture.

Serviervorschläge

These keto pizza stuffed peppers are a meal on their own, but pair beautifully with a crisp green salad dressed with olive oil and vinegar. For family members not following keto, you might serve them with a side of garlic bread. These peppers also make excellent leftovers—simply reheat in the microwave or oven until warmed through, or enjoy them cold for lunch the next day.
