# What You'll Need:

→ Bell Peppers

01 - 4 large bell peppers (any color), tops sliced off and seeds removed

→ Taco Filling

02 - 1.1 lb ground beef (80/20 blend)
03 - 1 small onion, finely chopped
04 - 2 cloves garlic, minced
05 - 1 medium tomato, diced
06 - 1 tablespoon tomato paste
07 - 1 teaspoon ground cumin
08 - 1 teaspoon chili powder
09 - 0.5 teaspoon smoked paprika

13 - 2 tablespoons olive oil

→ Cheese & Garnish

14 - 1 cup shredded cheddar cheese
15 - 2 tablespoons chopped fresh cilantro
16 - 2 tablespoons sliced scallions
17 - Sour cream for serving

# Method:

01 - Preheat oven to 375°F. Lightly grease a baking dish large enough to fit all bell peppers upright.
02 - Slice off pepper tops and remove seeds. Trim bases if needed to help peppers stand upright. Arrange in baking dish.
03 - Heat olive oil in a large skillet over medium heat. Add chopped onion and minced garlic, sautéing for 2-3 minutes until softened and fragrant.
04 - Add ground beef to skillet, breaking it into small pieces as it cooks. Continue cooking for 6-8 minutes until fully browned and cooked through. Drain excess fat if necessary.
05 - 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.
06 - Divide taco beef mixture evenly among the hollowed bell peppers, packing filling in gently.
07 - Sprinkle shredded cheddar cheese generously over the top of each stuffed pepper.
08 - Cover baking dish loosely with aluminum foil and bake for 20 minutes.
09 - Remove foil and continue baking for an additional 10 minutes until cheese is melted and bubbly.
10 - Remove from oven and garnish with fresh cilantro and sliced scallions. Serve hot with sour cream on the side if desired.

# Expert Pointers:

01 -
  • It tastes indulgent and spiced like real tacos but keeps your carbs under control without any guilt or weird substitutes.
  • The entire meal comes together in under an hour, and most of that time is just the oven working while you relax or prep something else.
  • Those melted cheese pools at the top get slightly crispy at the edges, and that texture contrast with the tender pepper is genuinely addictive.
02 -
  • If your peppers tip over in the baking dish, they'll lose filling and cook unevenly—this is why choosing peppers with flat, stable bases matters more than picking the prettiest colors.
  • Don't skip the step of draining excess fat from the beef, because too much grease in the filling makes it slide around and taste heavy instead of savory and satisfying.
  • Fresh shredded cheese melts into creamy pools, but pre-shredded cheese (which contains anti-caking agents) tends to separate and get grainy—I've learned this the hard way more times than I'd like to admit.
03 -
  • Use a sharp cheddar rather than mild—it melts better and has flavor depth that doesn't disappear under the spices like mild cheese does.
  • Don't skip the 10-minute uncovered bake at the end, because that's when the cheese edges get slightly crispy and the peppers develop a hint of char that tastes incredible.
