How To Make Stuffed Pepper Casserole
Ready to dive into this layered, cheesy bake? You’ll start by browning beef and aromatics, then let rice simmer in a flavorful tomato mixture before layering everything with crisp pepper slices in a casserole dish. A quick bake under foil steams the peppers and cooks the rice, and a final cheese-topped bake gives you that gooey, golden finish. Follow these detailed steps to nail each stage:
1. Preheat oven to 375°F (190°C) so it’s hot and ready when it’s time to bake.
2. In a large skillet, heat 2 tbsp olive oil over medium heat until shimmering.
3. Add chopped onion and minced garlic, cooking for about 3–4 minutes until softened and fragrant.
4. Add ground beef, breaking it up with a spoon, and cook until no longer pink and nicely browned.
5. Stir in uncooked rice, 2 cups water, diced tomatoes, tomato sauce, salt, pepper, and Italian seasoning; bring to a simmer, then let it bubble gently for about 5 minutes.
6. Grease a 9×13-inch baking dish and arrange half of the sliced bell peppers in an even layer on the bottom.
7. Pour the beef-and-rice mixture over the peppers, spreading it out, then top with the remaining pepper slices.
8. Cover the dish tightly with foil and bake for 40 minutes, allowing the peppers and rice to steam until tender.
9. Remove the foil, sprinkle 1 cup shredded cheddar cheese evenly over the top, and return to the oven uncovered for 10 minutes or until the cheese is melted and bubbly.
10. Let the casserole rest for 5 minutes before serving to let flavors settle and make slicing cleaner.
Serving Suggestions
These serving ideas will help you complement the hearty, cheesy casserole and turn it into a full, crowd-pleasing meal.

- Sour Cream Dollop: A spoonful of sour cream cools the bite and adds creamy richness.

- Freezing: After baking and cooling, portion into freezer-safe dishes. Press plastic wrap onto the surface to prevent ice crystals, then freeze up to 2 months.

Frequently Asked Questions
Here are some quick answers to your top questions—friendly, straightforward, and right to the point.
- How long does it take to prepare this recipe?
It takes about 15 minutes to prep (chopping onion, peppers, mincing garlic, measuring rice and spices), plus 40 minutes covered baking, 10 minutes uncovered, and a 5-minute rest—roughly 70 minutes total.
- Can I use pre-cooked rice instead of uncooked long grain white rice?
You can substitute pre-cooked rice but use only 1 cup water instead of 2 cups. Fold the rice in after browning the beef, simmer just to heat through, then proceed with layering and baking.
- Is it possible to assemble the casserole ahead of time?
Yes. Follow steps 1–7, cover tightly, and refrigerate up to 24 hours. When ready, bake covered for 40 minutes at 375°F, uncover, top with cheese, and bake 10 more minutes. You may need an extra 5–10 minutes if very cold.
- How can I keep the bell peppers from getting too soft or soggy?
Choose fresh, firm peppers and slice them evenly. Baking covered steams them gently; finishing uncovered helps evaporate excess moisture. For extra crunch, cut thicker strips and bake uncovered for the last 5–8 minutes instead of 10.
- What’s the best way to store and reheat leftovers?
Store in an airtight container in the fridge for up to 3 days. Microwave on medium-high for 2–3 minutes, stirring halfway, or reheat covered in a 350°F oven for about 15 minutes until warmed through.
- Can I freeze this casserole, and if so, how?
Yes. Cool completely, portion into freezer-safe containers, press plastic wrap on the surface, seal, and freeze up to 2 months. Thaw overnight in the fridge before reheating in a 350°F oven until hot and bubbly.
- How can I adapt the recipe for dietary preferences or extra flavor?
Swap ground beef for turkey or chicken to lighten it. Boost flavor with a mix of pepper colors, a pinch of red pepper flakes, or fresh herbs like basil. For dairy-free, omit cheddar or use a plant-based cheese.
