Ingredients

Scale
  • 14 oz tomato puree (use ½ of a 28-oz can)
  • 1 teaspoon Italian seasoning
  • ½ teaspoon dried garlic powder
  • ½ teaspoon dried onion powder
  • ½ teaspoon salt
  • pounds lean ground beef (at least 80% lean)
  • 1 medium onion, finely chopped (1 cup)
  • 2 cloves garlic, minced
  • 2 teaspoons Italian seasoning
  • 1 teaspoon salt
  • 1¼ cups parboiled rice (uncooked)
  • 68 medium-large bell peppers, tops sliced off and cores removed (any color)
  • Shredded mozzarella cheese (optional, for topping)

Instructions

  1. In a medium bowl, mix together tomato puree, Italian seasoning, garlic powder, onion powder, and salt to make the sauce.
  2. In a large bowl, mix the ground beef, onion, garlic, additional Italian seasoning, salt, and parboiled rice until well combined.
  3. Ladle a small amount of sauce into the bottom of a 6–7 quart crock pot to prevent sticking.
  4. Stuff the prepared peppers with the meat and rice mixture, filling them just below the rim.
  5. Place stuffed peppers upright in the crockpot. Slight stacking is fine if the lid closes properly.
  6. Pour remaining sauce evenly over the peppers.
  7. Cover and cook on LOW for 5–6 hours or HIGH for 2–3 hours, until the filling is fully cooked through.
  8. Optional: Sprinkle cheese on top of each pepper, close lid, and cook an additional 5 minutes until cheese melts.

Notes

  • Always place sauce at the bottom to avoid burning.
  • Do not overstuff peppers – rice expands during cooking.
  • Use 80% or leaner beef to prevent greasy texture.
  • Pizza sauce can be used in place of tomato puree with seasoning adjustments.
  • Peppers can be prepped the night before and cooked in the morning.
  • Stuffed peppers freeze well and reheat best in the oven.
