Description
A cozy, cheesy Stuffed Pepper Casserole with bell peppers, ground beef, rice, and a savory tomato sauce—easy, one-pan comfort food ready in 45 minutes.
Ingredients
1 tbsp olive oil
1 lb ground beef (or turkey)
1 yellow onion, diced
3 bell peppers (any colors), diced
3 garlic cloves, minced
1 cup long-grain white rice, uncooked
1 (15 oz) can tomato sauce
1 (14.5 oz) can diced tomatoes, with juices
2 cups low-sodium beef broth (or chicken broth)
1 tbsp tomato paste
1 tsp Italian seasoning
1 tsp smoked paprika
1 tsp kosher salt (plus more to taste)
1/2 tsp black pepper
1/2 tsp crushed red pepper flakes (optional)
1 tsp Worcestershire sauce
1 cup shredded mozzarella
1/2 cup shredded sharp cheddar
2 tbsp fresh parsley, chopped (for garnish)
Instructions
1. Preheat oven to 375°F (190°C).
2. Heat olive oil in a large oven-safe skillet over medium heat. Sauté onion and bell peppers 5–6 minutes; add garlic 30 seconds.
3. Add ground beef; cook until browned, 5–7 minutes. Drain excess fat.
4. Stir in Italian seasoning, smoked paprika, salt, pepper, red pepper flakes, and Worcestershire; cook 1 minute.
5. Stir in rice, tomato paste, tomato sauce, diced tomatoes with juices, and broth. Bring to a simmer, cover, and cook 10 minutes, stirring once.
6. Uncover, stir, smooth the top, and sprinkle with mozzarella and cheddar.
7. Bake 10–12 minutes until rice is tender and cheese is bubbly.
8. Rest 5 minutes, garnish with parsley, and serve.
Notes
For brown rice, par-cook before adding. For low-carb, use cauliflower rice and bake less. Adjust salt to taste and tent with foil if cheese browns too quickly.

Easy Stuffed Pepper Casserole (Meal-Prep & Budget)
One-pan method for Stuffed Pepper Casserole
The beauty of Stuffed Pepper Casserole is the one-pan flow. Start on the stovetop to build flavor—sauté the onion and bell peppers, brown the ground beef, then season generously. Stir in rice so it toasts lightly in the fat and spices; that step infuses the grain with flavor. Add tomato sauce, diced tomatoes, and broth, then simmer until the rice begins to swell. Finish in the oven so the rice cooks through and the top turns into a cheesy, golden lid. This Stuffed Pepper Casserole technique captures the spirit of stuffed peppers with half the work and all the comfort food vibes.
Practical, time-saving tips
- Dice peppers and onions on Sunday; stash in a sealed container. Weeknight Stuffed Pepper Casserole then hits the oven in minutes.
- Use pre-shredded mozzarella and cheddar for speed. Freshly grated melts creamier, but weeknights are about balance.
- Choose long-grain white rice for a classic, tender finish. If using brown rice, par-cook it first to protect the Stuffed Pepper Casserole texture.
- Ground turkey or plant-based crumbles make this casserole lighter without losing the deconstructed stuffed peppers vibe.
- Batch-cook: double the recipe in two skillets; bake one now, freeze the other for a future cozy night.
Meal prep bonus: This Stuffed Pepper Casserole holds up like a champ. Individual portions reheat beautifully for lunches. Love a comfort-food lineup?

Healthy Variations
Low-carb, dairy-light, and gluten-free ideas
Want a lighter Stuffed Pepper Casserole without sacrificing flavor? Try cauliflower rice for a low-carb twist—add it in the last 5 minutes of simmering so it doesn’t turn mushy. Go dairy-light by topping with a modest layer of part-skim mozzarella or skipping cheddar. Keep it gluten-free with certified GF broth and seasonings. For extra veg, toss in chopped zucchini or spinach during the stovetop simmer. You’ll still enjoy the bell peppers, tomato sauce, and cozy casserole finish, all while keeping the Stuffed Pepper Casserole wholesome, hearty, and weeknight-ready.

Troubleshooting and pro tips
- Rice not tender? Add 1/4 cup hot broth, cover, and bake 5 more minutes. Stuffed Pepper Casserole should be saucy, not dry.
- Too watery? Simmer uncovered a few minutes before baking, or let the casserole rest 5–10 minutes so the rice absorbs.
- Bland? Increase salt and smoked paprika; a squeeze of lemon can brighten the entire casserole.
- Want more veggies? Add diced carrots or baby spinach—this Stuffed Pepper Casserole loves color and crunch.
- Cheese browning too fast? Tent with foil until the Stuffed Pepper Casserole is fully heated through.
