Having everything within reach will help speed things up. Ensure your large skillet is clean and ready for action as it will be your main cooking tool for this dish.
Additionally, for this recipe, a wooden spoon or spatula will be a great asset for mixing and browning the sausage and vegetables. You might also want to have measuring cups or spoons on hand for accuracy with the rice and seasonings. Before you start cooking, give your work surface a quick wipe-down to keep everything hygienic.

Ingredients
- 1 lb Italian sausage (mild or spicy)
- 1 cup uncooked long-grain white rice (or brown rice)
- 3 bell peppers (any color, diced)
- 1 onion, diced
- 2 cloves garlic, minced
- 1 cup salsa (or tomato sauce)
- 1 cup chicken broth
- 1 tsp oregano
- 1 tsp cumin
- Salt and pepper, to taste
- 1 cup shredded mozzarella cheese
Instructions
Step 1: Cook the Sausage
Begin by heating a large skillet over medium-high heat. Squeeze the Italian sausage out of its casings and into the skillet. Use a wooden spoon to break up the meat as it browns, allowing it to cook for about 5 to 7 minutes or until fully cooked and browned. The goal is to obtain a nice sear that enhances the flavor of the sausage. Once it’s browned, incorporate the diced bell peppers and onion into the skillet. Cook this mixture for an additional 3 to 5 minutes, stirring continuously until the veggies soften and become fragrant.
Step 2: Season and Stir
Next, introduce your minced garlic, oregano, cumin, salt, and pepper to the pan. Stir everything to combine well, letting the seasonings coat the sausage and vegetables evenly. Allow this mixture to cook for about a minute, which boosts the flavors and brings out the aromatic qualities of the spices.
Step 3: Add Liquids
Pour the chicken broth and salsa into the skillet, stirring to combine and scraping up any browned bits from the bottom of the pan—this is where a lot of flavor resides. Be sure to get every last bit for a rich-tasting casserole. Then, bring the mixture to a gentle simmer.
Step 4: Add Rice
Once simmering, stir in the rinsed rice ensuring it is evenly distributed throughout the mixture. Cover the skillet and reduce the heat to low, allowing it to cook undisturbed for about 15 to 20 minutes. This time will allow the rice to absorb the liquids and steam in the flavors, resulting in a tender consistency. Keep an eye on it to ensure that no excess liquid remains, because you want your casserole to be moist but not soupy.
Step 5: Add Cheese
Last but certainly not least, sprinkle shredded mozzarella over the top of the casserole. Cover the skillet once more and allow it to sit for about 5 minutes to let the cheese melt beautifully and form a delicious, gooey topping. Serve hot and enjoy the delightful aroma that fills your kitchen.

Variations
- Protein: Feel free to substitute Italian sausage with ground beef, chicken, or turkey for varying flavors.
- Vegetables: Add in or swap any favorite veggies such as zucchini, corn, or black beans for additional nutrition.
- Spices: Enhance or adjust the flavor profile by adding chili powder, paprika, or even some crushed red pepper for heat.
Cooking Notes
- For optimal flavor, don’t skip browning the sausage and vegetables—not only do they taste better, but you’ll appreciate the depth of flavor!
- If using brown rice, remember that it will require a longer cooking time, so plan accordingly to accommodate its cooking time difference.
Serving Suggestions
- Pair with a fresh green salad to balance the hearty flavors of the casserole.
- Serve with crusty garlic bread to soak up any extra sauce left on the plate.
Tips
- Make sure to rinse the rice before adding it to the skillet; this helps remove excess starch and prevents clumping.
- If you have leftovers, store them in an airtight container in the refrigerator for up to 3 days—reheat in the microwave or on the stovetop.
