Ingredients
  

  • 4 large bell peppers (any color), tops sliced off and seeds removed
  • 1.5 pounds ground beef (80/20 or 85/15)
  • 1 small onion, finely diced
  • 2 cloves garlic, minced
  • 1 tablespoon chili powder (or to taste)
  • 2 teaspoons ground cumin
  • 1 teaspoon smoked paprika
  • 1 teaspoon dried oregano
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon salt, plus more to taste
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon crushed red pepper flakes (optional for heat)
  • 3 tablespoons tomato paste (low-sugar)
  • 1/2 cup beef broth (low-sodium)
  • 1 tablespoon apple cider vinegar or lime juice
  • 1 cup shredded cheddar or Mexican blend cheese, divided
  • 1/2 cup shredded Monterey Jack or pepper jack (optional for extra melt)
  • 2 tablespoons olive oil or avocado oil
  • Fresh cilantro, chopped (optional)
  • For serving: sour cream, sliced jalapeños, diced avocado, salsa (no-sugar-added)

Method
 

  1. Preheat and prep the peppers: Heat your oven to 400°F (205°C). Slice the tops off the bell peppers and remove seeds and membranes. Lightly brush the insides with olive oil and a pinch of salt. Place them upright in a baking dish.
  2. Par-bake the peppers: Bake the empty peppers for 10–12 minutes to soften them slightly. This helps them cook through and avoids a crunchy texture later.
  3. Sauté the aromatics: While the peppers bake, heat the remaining oil in a large skillet over medium. Add diced onion and cook 3–4 minutes until softened. Stir in minced garlic and cook 30 seconds until fragrant.
  4. Brown the beef: Add ground beef to the skillet. Break it up and cook until browned, about 6–8 minutes. Drain excess fat if needed, leaving about a tablespoon in the pan for flavor.
  5. Season it up: Stir in chili powder, cumin, smoked paprika, oregano, garlic powder, onion powder, salt, pepper, and red pepper flakes if using. Toast the spices for 30 seconds to wake up the flavors.
  6. Add tomato paste and broth: Mix in the tomato paste and cook 1 minute. Pour in beef broth and simmer 2–3 minutes until the mixture thickens slightly. Stir in apple cider vinegar or lime juice to brighten the flavors. Taste and adjust salt.
  7. Cheese it: Turn off the heat. Fold in 1/2 cup shredded cheddar and 1/2 cup Monterey Jack (if using). The cheese will melt and help hold the filling together.
  8. Fill the peppers: Spoon the beef mixture into each par-baked pepper, packing it down gently. Mound it a little higher than the rim.
  9. Top and bake: Sprinkle the remaining 1/2 cup cheddar over the peppers. Return to the oven and bake 12–15 minutes, until the cheese is melted and bubbly and peppers are tender.
  10. Garnish and serve: Let cool for 5 minutes. Top with fresh cilantro and serve with sour cream, jalapeños, diced avocado, or a spoon of low-sugar salsa.
