How to Make Stuffed Pepper Casserole Recipe
Step 1: Preheat and Sauté
Start by heating your oven to 375 degrees Fahrenheit to ensure the perfect baking environment later. Next, warm a tablespoon of olive oil in a large ovenproof skillet or Dutch oven over medium heat. Add the diced onion, minced garlic, bell peppers, and lean ground beef. Sauté these until the beef is nicely browned and the vegetables have softened, about 10 minutes. This step builds the flavorful foundation that will make your casserole shine.
Step 2: Add Remaining Ingredients
Once your beef and peppers have melded beautifully, pour in the tomato sauce and the can of petite diced tomatoes. Sprinkle in salt, pepper, dried basil, oregano, and parsley for that herby kick. Stir in the uncooked minute rice and pour the beef broth over everything. Give it a good stir to combine all these amazing ingredients evenly.
Step 3: Bake
Cover your skillet with aluminum foil to keep the moisture locked in while the rice cooks. If you don’t have an ovenproof skillet, simply transfer the mixture to a casserole dish and cover tightly. Slide it into the 375-degree oven and bake for 20 minutes, allowing the rice to absorb all those juicy flavors and become tender.
Step 4: Add Cheese
After the 20-minute bake, remove the foil and sprinkle the part-skim mozzarella evenly over the top. Return the dish to the oven uncovered and bake for an additional 10 minutes. Watch as the cheese melts to a bubbly, slightly browned perfection that will have your mouth watering in no time.
Step 5: Serve
By now, the rice should have soaked up all the delicious liquid, and everything will be hot, bubbly, and ready to delight your tastebuds. Grab a big scoop and get ready to enjoy a dinner that’s as satisfying as it is colorful.

Garnishes
Sprinkle some freshly chopped parsley or even a handful of chopped basil on top for a fresh, herbaceous touch. A light drizzle of olive oil or a pinch of crushed red pepper flakes can also add a subtle extra dimension to this comforting casserole.
Side Dishes

Creative Ways to Present

Make Ahead and Storage
Storing Leftovers
Leftover casserole keeps beautifully in an airtight container in the refrigerator for up to 3 days. The flavors continue to meld, making the next day’s meal just as tasty, if not more.
Freezing
You can freeze this casserole either before baking or after it’s cooled down post-bake. Wrap it tightly in plastic wrap and foil to prevent freezer burn and store for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating
Reheat individual servings in the microwave until steaming throughout. For larger portions, warm in an oven-safe dish covered with foil at 350 degrees Fahrenheit until heated through and bubbly again, about 20 minutes.
