Ingredients

Scale

Meat and Vegetables

  • ¾ pound ground Italian sausage (mild or spicy) (375g)
  • 2 cups chopped bell peppers
  • ½ medium onion, finely chopped
  • 2 cloves garlic, finely minced

Seasonings and Spices

  • ¾ teaspoon salt
  • ½ teaspoon dried oregano
  • ¼ teaspoon black pepper
  • ¼ teaspoon ground cumin

Liquids

  • 2 cups low-sodium chicken broth
  • 1 cup tomato salsa

Other Ingredients

  • 1 cup long-grain white rice, rinsed
  • 1 cup shredded mozzarella cheese

Instructions

  1. Cook the sausage and vegetables: In a large skillet over medium-high heat, crumble and cook the ground Italian sausage until it just starts to brown. Add the chopped bell peppers and onion, cooking for about 5 minutes while stirring often, until the vegetables are crisp-tender.
  2. Add spices and garlic: Stir in the minced garlic, salt, dried oregano, black pepper, and ground cumin. Cook for 1 more minute to release the aromas and flavors.
  3. Add liquids and scrape skillet: Pour in the low-sodium chicken broth and use a wooden spoon to scrape any browned bits off the bottom of the skillet to incorporate extra flavor. Stir in the tomato salsa.
  4. Add rice: Rinse the long-grain white rice well under cold water and drain. Add the rice to the skillet and stir everything together thoroughly.
  5. Simmer the casserole: Bring the mixture to a simmer over medium heat. Cover, reduce the heat to medium-low, and let it simmer gently for 15 to 20 minutes until the rice is fully cooked and tender.
  6. Finish with cheese: Sprinkle the shredded mozzarella cheese evenly over the top of the casserole. Cover again and let the cheese melt before serving hot.

Notes

  • The sausage can be substituted with ground turkey or chicken for a leaner option.
  • Adjust the heat level by choosing mild or spicy Italian sausage or adding chili flakes.
  • Use low-sodium broth and salsa to control salt levels.
  • Make sure to rinse the rice well to remove excess starch and prevent sticking.
  • Leftovers store well and can be reheated in a skillet or microwave.
