  • ¾ pound ground Italian sausage, mild or spicy (375g)
  • 2 cups chopped bell peppers
  • ½ medium onion, finely chopped
  • 2 cloves garlic, finely minced
  • ¾ teaspoon salt
  • ½ teaspoon dried oregano
  • ¼ teaspoon pepper
  • ¼ teaspoon cumin
  • 2 cups low-sodium chicken broth
  • 1 cup tomato salsa
  • 1 cup long-grain white rice, rinsed
  • 1 cup shredded mozzarella cheese

How to Make It

Brown the Sausage

Warm a large skillet over medium-high heat and crumble in the sausage. Let it cook until it starts to brown and build those delicious, savory bits on the bottom the foundation of any good nourishing homemade meal.

Soften the Peppers & Onion

Add your bell peppers and onion. Let them cook about 5 minutes, stirring often. They should stay a little crisp, giving the casserole that signature stuffed-pepper texture and a hint of healthy comfort.

Season & Bloom the Garlic

Stir in the garlic, salt, oregano, pepper, and cumin. Just one minute is enough for the garlic to bloom and the spices to warm, creating that deeper, homey aroma that fills the whole kitchen.

Add Broth & Salsa

Pour in the chicken broth and gently scrape up those browned bits. Stir in the salsa this brings in acidity, richness, and a little brightness without extra work. It’s the kind of small shortcut that keeps weeknight cooking joyful and budget-friendly.

Add the Rice

Rinse the rice under cold water until it runs clear. Drain well and add it to the skillet. Stir everything together and bring it to a gentle simmer, letting the grains soak up all the color and flavor.

Simmer Until Tender

Lower the heat to medium–low, cover, and let it simmer 15–20 minutes until the rice is tender and fluffy. This is the part where dinner practically cooks itself a perfect moment to reset from the day.

Finish with Cheese

Sprinkle mozzarella over the top, cover again, and let the casserole rest until the cheese melts into a warm, stretchy layer. It turns the skillet into a true family-style comfort meal.
