Ingredients

Scale
  • 1 lb ground beef (85% lean recommended)
  • 1 medium yellow onion, diced
  • 3 large bell peppers (red, green, yellow), chopped
  • 3 cloves garlic, minced
  • 1 can (28 oz) crushed tomatoes
  • 1 can (14.5 oz) diced tomatoes, undrained
  • 4 cups beef broth (low-sodium preferred)
  • 1 tbsp tomato paste
  • 1 tsp smoked paprika
  • 1 tsp dried oregano
  • 1 tsp dried basil
  • 1/2 tsp black pepper
  • 1/2 tsp kosher salt (plus more to taste)
  • 1 tbsp Worcestershire sauce
  • 3/4 cup uncooked long-grain white rice
  • Chopped fresh parsley (for garnish)
  • Shredded mozzarella or cheddar cheese (optional, for serving)

Instructions

  1. In a large skillet over medium heat, brown the ground beef until no pink remains, about 6-8 minutes. Drain excess fat if needed.
  2. While beef browns, dice onion, chop bell peppers, and mince garlic.
  3. Transfer cooked beef to a 6-quart slow cooker. Add onion, bell peppers, and garlic.
  4. Pour in crushed tomatoes, diced tomatoes (with juices), beef broth, and tomato paste. Stir gently.
  5. Add smoked paprika, dried oregano, dried basil, black pepper, kosher salt, and Worcestershire sauce. Stir to combine.
  6. Cover and cook on LOW for 6-7 hours or HIGH for 3-4 hours, until peppers are soft and flavors blended.
  7. About 30 minutes before serving, stir in uncooked rice. Re-cover and cook until rice is tender. (For brown rice, add 45-60 minutes before serving; for instant or cauliflower rice, add just 10 minutes before serving.)
  8. If soup is too thick, add up to 1 cup extra beef broth. If too thin, cook uncovered for 10-15 minutes to reduce.
  9. Taste and adjust salt as needed.
  10. Ladle soup into bowls. Garnish with chopped parsley and shredded cheese, if desired.
  11. Store leftovers in airtight containers. Add a splash of broth when reheating, as rice will absorb liquid.

Notes

Add rice late in the cooking process to prevent mushiness. For a lighter version, use ground turkey or chicken. For vegetarian, use plant-based ground meat and vegetable broth. Soup thickens as it sits; add broth when reheating. Freeze without rice for best texture. Customize with beans, extra veggies, or spice as desired.
