Ingredient Highlights
Bell Peppers
Choose firm, vibrant bell peppers that are heavy for their size. Red, yellow, and orange peppers are sweeter, while green ones have a slightly bitter flavor. Removing all seeds and pith ensures a smooth, uniform filling and prevents excess moisture.
Ground Beef
Opt for lean ground beef (85% lean) for the perfect balance of flavor and fat. The fat helps enrich the filling, keeping it juicy and satisfying. Ground turkey or chicken can also be used for a lighter option.
Keto-Friendly Tomato Sauce
Select a low-sugar, keto-approved tomato sauce or make your own with fresh tomatoes, garlic, and Italian herbs. Tomato paste can be added for extra thickness.
Cheeses
- Mozzarella: Adds gooey, melty texture.
- Ricotta: Provides creamy richness that balances the savory beef.
- Parmesan: Offers sharp, nutty notes that enhance flavor complexity.
Seasonings and Aromatics
- Fennel seeds: Impart a subtle anise flavor reminiscent of Italian sausage.
- Olive oil: Used for sautéing and enhancing aroma.
- Optional: garlic, onion, Italian herbs, red pepper flakes for added depth.
Pro Tips Before You Start
- Prevent Soggy Peppers: Dry bell peppers thoroughly and avoid overfilling.
- Concentrate Flavor: Cook the beef mixture until thickened to intensify taste.
- Meal Prep: Assemble peppers ahead of time, refrigerate, and bake when ready.
- Cheese Topping: Add some cheese midway through baking for an evenly melted, golden finish.
- Resting: Let refrigerated peppers come to room temperature before baking to ensure even cooking.
