How to Make Stuffed Pepper Casserole Step by Step
Step 1: Cook the Meat
Start by browning the ground beef in a large skillet over medium heat. Add the chopped onion and cook until softened and fragrant. Stir in the garlic and cook for another minute to release its flavor.
Step 2: Combine Everything
Add the cooked rice, diced tomatoes with their juices, tomato sauce, chopped bell peppers, and seasonings to the skillet. Stir everything together until well combined and evenly distributed.
Step 3: Transfer to Baking Dish
Pour the mixture into a greased baking dish and spread it out into an even layer so it cooks evenly.
Step 4: Add the Cheese
Sprinkle the shredded cheese generously over the top. This will melt into a delicious, golden layer as the casserole bakes.
Step 5: Bake Until Bubbly
Cover the dish with foil and bake until everything is heated through. Then uncover and continue baking until the cheese is melted and lightly golden on top.
Expert Tips
For the best flavor, let the meat mixture simmer for a few extra minutes before baking. This helps the spices blend beautifully.
If you like a bit of heat, add a pinch of red pepper flakes or diced chili peppers to the mix.
You can also use pre-cooked or leftover rice to save time without sacrificing texture.
How to Store and Reheat It
Store leftovers in an airtight container in the refrigerator for up to 3 days. This casserole reheats beautifully, making it perfect for meal prep.
To reheat, warm it in the oven at 325°F until heated through, or microwave individual portions for a quick meal.
What to Serve With
This casserole is a complete meal on its own, but it pairs nicely with a simple green salad, garlic bread, or even roasted vegetables for a balanced plate.
Frequently Asked Questions
