I first made this Stuffed Pepper Casserole Recipe on a busy weeknight when I wanted something comforting but simple. I didn’t have time to stuff individual peppers, so I turned everything into a baked casserole.
The result was even better than I expected—hearty, flavorful, and super satisfying. Now I make it whenever I want a quick family dinner with minimal effort. Trust me, this recipe will become one of your go-to comfort meals too.
Ingredients
Here’s everything you’ll need to make this delicious stuffed pepper casserole:
- Ground beef (1 lb) – I prefer 85/15 for the best balance of flavor and moisture without excess grease.
- Bell peppers (3 large, chopped) – Use a mix of red, green, and yellow for sweetness and color.
- Onion (1 medium, diced) – Adds depth and savory aroma to the dish.
- Garlic (3 cloves, minced) – Fresh garlic gives the casserole its signature flavor boost.
- Cooked rice (2 cups) – Day-old rice works best because it holds texture better.
- Tomato sauce (2 cups) – Forms the rich base that ties everything together.
- Diced tomatoes (1 can, 14 oz) – Adds juiciness and slight acidity.
- Italian seasoning (1 tsp) – A simple herb blend for classic comfort flavor.
- Paprika (1/2 tsp) – Gives a subtle smoky warmth.
- Salt and black pepper (to taste) – Essential for balancing flavors.
- Shredded cheese (1 1/2 cups) – Freshly grated cheese melts smoother than pre-shredded.
- Olive oil (1 tbsp) – Helps sauté vegetables and enhances richness.
Note: Serves 6 generous portions as a complete meal.

How to Make Stuffed Pepper Casserole Recipe?
Step 1: Prepare the Ingredients
I start by washing and chopping all vegetables before cooking. This makes the cooking process smooth and stress-free. Having everything ready helps me avoid burning anything later.
Step 2: Cook the Ground Beef
I heat olive oil in a skillet and cook the beef until browned. Then I add onions and garlic to build flavor into the meat. This step creates a rich, savory base for the casserole.
Step 3: Add Vegetables and Sauce
Next, I mix in chopped bell peppers and cook until slightly tender. I pour in tomato sauce and diced tomatoes for moisture and flavor. Everything simmers together until well combined and aromatic.
Step 4: Mix with Rice
I stir in the cooked rice and season everything with herbs and spices. The mixture becomes thick, hearty, and full of comforting texture. This is where all the flavors start blending beautifully.
Step 5: Bake the Casserole
I transfer the mixture into a baking dish and top it with cheese. Then I bake until the cheese melts and becomes golden and bubbly. This final step gives the casserole its irresistible finishing touch.
Additional Tips for Making This Recipe Better
From my experience, small changes can really improve the flavor, especially when you explore similar cozy baked dishes like layered-sweet-potato-squash-carrot-bake-with-cranberry-honey-drizzle, which follows the same comforting oven-baked style with natural sweetness.
- I always use freshly grated cheese because it melts creamier.
- Letting the casserole rest for 5–10 minutes makes serving easier.
- I sometimes add a splash of Worcestershire sauce for deeper flavor.
- Cooking peppers slightly before baking prevents them from staying too crunchy.
- I prefer day-old rice because it doesn’t turn mushy in the casserole.
How to Serve Stuffed Pepper Casserole Recipe?
I like serving this casserole hot straight from the oven for the best taste. A sprinkle of fresh parsley or green onions adds a fresh finishing touch. It pairs beautifully with garlic bread or a simple green salad.
For presentation, I serve it in a deep dish to highlight its cheesy top layer. If you want a sweet ending after this hearty meal, something like poppy-seed-lemon-crepes-recipe works perfectly as a light dessert contrast.
