Instructions

1. Preheat and Prep Dish
Preheat oven to 190°C (375°F). Lightly grease a baking dish large enough to fit all bell peppers upright.
2. Prepare Bell Peppers
Slice off the tops and remove seeds from the peppers. If needed, trim the base slightly to help them stand upright. Place them in the baking dish.
3. Sauté Aromatics
Heat olive oil in a large skillet over medium heat. Add onion and garlic, and sauté for 2–3 minutes until softened.
4. Cook Beef
Add ground beef and cook, breaking it up with a spatula, until browned and cooked through (about 6–8 minutes). Drain excess fat if necessary.
5. Season Filling
Stir in diced tomato, tomato paste, cumin, chili powder, smoked paprika, oregano, salt, and pepper. Simmer for 3–4 minutes until fragrant and slightly thickened.
6. Stuff Peppers
Spoon the taco beef mixture evenly into the hollowed bell peppers, packing it in gently.
7. Add Cheese
Sprinkle shredded cheddar cheese generously over the tops of the stuffed peppers.
8. Bake
Cover loosely with foil and bake for 20 minutes. Uncover and bake for an additional 10 minutes, or until cheese is melted and bubbly.
9. Garnish and Serve
Remove from oven. Garnish with chopped cilantro and scallions if desired. Serve hot, with a dollop of sour cream if liked.

Zusatztipps für die Zubereitung

For an extra kick of heat, try adding a few jalapeño slices to the taco beef filling or placing them directly on top of the cheese before the final bake. Ensuring your ground beef is well-drained after browning helps prevent the peppers from becoming too watery at the bottom.

Varianten und Anpassungen

This recipe is highly versatile; you can substitute the ground beef with ground turkey or chicken for a lighter protein option. For a dairy-free version, simply replace the cheddar cheese with your favorite plant-based cheese alternative.

Serviervorschläge

Pair these stuffed peppers with fresh avocado slices or a crisp side salad to round out the meal. A generous dollop of sour cream on top provides a cool contrast to the warm, spiced meat filling.
