Ingredients You’ll Need

For the Stuffed Peppers

• 4 large bell peppers — serve as the low-carb vessel while adding sweetness, color, and nutrients.
• 1 lb ground beef (85/15) — provides a juicy, flavorful base similar to classic lasagna meat sauce.
• 1 cup low-carb marinara sauce (no sugar added) — adds tomato richness while keeping carbohydrates lower.
• 1 cup whole milk ricotta cheese — creates the creamy layer traditionally found in lasagna.
• 2 cups shredded mozzarella cheese — provides a stretchy, golden melted cheese topping.
• ½ cup grated Parmesan cheese — adds salty, nutty depth to the filling.
• 1 large egg — helps bind the ricotta mixture and creates a stable creamy layer.
• 2 cloves garlic, minced — enhances the savory Italian flavor.
• 1 teaspoon dried Italian seasoning — adds classic herb notes from oregano, basil, and other spices.
• ½ teaspoon salt — balances and enhances the flavors.
• ¼ teaspoon black pepper — adds mild spice and brightness.
• 2 tablespoons fresh parsley, chopped — provides freshness and a colorful finishing touch.

Step-by-Step Instructions

1. Prepare the Peppers

Preheat the oven to 400°F (200°C) and lightly grease a 9×13-inch baking dish. Slice the bell peppers in half lengthwise, remove the seeds and membranes, then place them in the baking dish.

2. Pre-Bake the Pepper Shells

Bake the prepared peppers for 15 minutes until they begin to soften slightly. This step helps ensure the peppers become tender while preventing the filling from overcooking later.

3. Cook the Beef Filling

Heat a large skillet over medium-high heat and brown the ground beef until fully cooked. Drain excess fat to prevent the filling from becoming greasy while keeping the meat flavorful.

4. Build the Meat Sauce

Add minced garlic, marinara sauce, Italian seasoning, salt, and black pepper to the cooked beef. Simmer for 5 minutes to allow the flavors to combine and the sauce to slightly thicken.

5. Prepare the Ricotta Layer

In a mixing bowl, combine ricotta cheese, Parmesan cheese, egg, and half of the shredded mozzarella. Stir until smooth and evenly combined for a creamy lasagna-style filling.

6. Assemble the Stuffed Peppers

Layer the meat sauce and ricotta mixture inside each pre-baked pepper half. Fill evenly and finish with the remaining mozzarella cheese on top for a golden cheesy crust.

7. Bake Until Golden

Cover the baking dish with foil and bake for 20 minutes. Remove the foil and continue baking for another 5–10 minutes until the cheese is melted, bubbly, and lightly golden.

8. Rest and Serve

Allow the stuffed peppers to rest for a few minutes before serving. This helps the filling set slightly and makes each portion easier to enjoy.

Recipe Notes & Tips

• Choose Firm Peppers — Select large peppers with thick walls so they hold the filling well during baking.
• Drain Excess Meat Fat — Removing extra grease keeps the filling balanced and prevents oily sauce.
• Use Freshly Grated Cheese — Fresh mozzarella and Parmesan generally melt better and provide better flavor than pre-shredded varieties.
• Do Not Skip Pre-Baking — Softening the peppers first ensures they become tender without requiring excessive cooking time.
• Let Them Rest Before Serving — A short resting period helps the cheese and filling maintain their structure.
• Prepare Ahead for Convenience — Assemble the peppers in advance and refrigerate until ready to bake.
