Instructions

Step 1
Preheat oven to 190°C (375°F). Lightly grease a baking dish large enough to fit all bell peppers upright.
Step 2
Prepare the bell peppers: Slice off the tops and remove seeds. If needed, trim the base to help them stand upright. Place in the baking dish.
Step 3
Heat olive oil in a large skillet over medium heat. Add onion and garlic, sauté for 2–3 minutes until softened.
Step 4
Add ground beef and cook, breaking it up, until browned and cooked through (about 6–8 minutes). Drain excess fat if necessary.
Step 5
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.
Step 6
Spoon the taco beef mixture evenly into the hollowed bell peppers, packing it in gently.
Step 7
Sprinkle shredded cheddar cheese generously over the tops of the stuffed peppers.
Step 8
Cover loosely with foil and bake for 20 minutes. Uncover and bake for an additional 10 minutes, or until cheese is melted and bubbly.
Step 9
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, you can add a few jalapeño slices to the taco filling during the simmering stage or place them on top of the cheese before baking. Always ensure you check the labels of your tomato paste and cheese to avoid hidden gluten or additives if you have specific dietary sensitivities.
