Bright tomato flavor and an abundance of bell peppers make this a stuffed pepper casserole that is easy to make and delicious. No fussing with balancing the peppers and filling them. If you like stuffed peppers, you’ll love this version! All you have to do is brown the meat, sauté the veggies, add the rice and remaining ingredients, and bake. It’s that easy, and all in one oven-safe skillet. If you don’t have a deep oven-safe skillet with a lid, transfer the casserole ingredients to a baking dish, cover it with foil, and bake as directed.

Recipe Variations

Mexican Inspired: Add some black beans and season the meat (try fresh Mexican chorizo) mixture with taco seasoning or chili powder. Top the finished dish with diced avocado and cilantro, or serve it with sour cream or guacamole.

Italian-inspired: Use part or all Italian sausage, sliced mushrooms, Italian seasoning, or oregano for flavor, and mozzarella cheese.

Spicy: Add diced jalapeño, Fresno, or poblano peppers, and use pepper jack cheese. Finish the dish with a drizzle of hot sauce.

What to Serve With a Stuffed Pepper Casserole

Bread: A crusty bread is an excellent choice, or you might serve the stuffed pepper casserole with a bread machine focaccia or this pull-apart garlic loaf made with biscuits. These garlic butter crescent rolls are easy to fix and delicious with the dish.

Salad: The tanginess of a Caesar salad or green salad with a simple vinaigrette would complement the stuffed pepper flavors. You can also serve the casserole with a side of coleslaw.
