How to Make Stuffed Pepper Casserole
- Brown the sausage in a large skillet over medium-high heat until it starts to color.
- Add chopped bell peppers and onions, cooking until just tender, about 5 minutes.
- Stir in minced garlic, oregano, cumin, salt, and pepper; cook for 1 minute.
- Pour in chicken broth, scraping up browned bits for extra flavor.
- Stir in salsa, then add rinsed rice and mix well.
- Bring to a simmer, cover, and reduce heat. Cook for 15–20 minutes, or until rice is tender.
- Sprinkle mozzarella over the top, cover, and let melt before serving.

Tips & Tricks for the Best Casserole
• Rinse rice before cooking to prevent gumminess.
• Use a well-seasoned salsa for maximum flavor without extra spices.
• For oven-baked version, transfer to a casserole dish, cover, and bake at 350°F for 20–30 minutes.
• Let it rest for 5 minutes before serving so flavors settle and cheese firms slightly.
Pairing Ideas & Variations
• Serve with garlic bread or a crisp green salad for a complete meal.
• Pair with roasted vegetables like asparagus or broccoli for extra nutrition.
• Make ahead by preparing up to the rice-cooking step, then refrigerating and reheating when ready to eat.
• Freeze in portions for quick weekday dinners — just thaw overnight and reheat with a splash of broth.
Health & Nutrition Benefits
This stuffed pepper casserole offers a good balance of protein, carbs, and vegetables in each serving. Bell peppers provide vitamin C, rice adds energy-sustaining carbs, and sausage delivers protein and iron. Opt for leaner meat and brown rice for a lighter, higher-fiber version without sacrificing flavor.
