Stuffed Peppers & Rice Casserole

There are some dinners that feel like a warm hug from your childhood kitchen, and this Stuffed Peppers & Rice Casserole is exactly that. It takes everything you love about classic stuffed peppers—the tender peppers, the savory beef and rice filling, the rich tomato sauce, and the melted cheese on top—and transforms it into a cozy, scoopable casserole that feeds a crowd without any of the fussy individual stuffing.

What I love most about this recipe is how effortlessly it comes together. Instead of carefully hollowing out and filling whole peppers, you simply chop the peppers, layer them with a hearty beef and rice mixture, and bake everything together in one dish. You get all the flavor and comfort of the classic with a fraction of the work. The peppers soften into sweet, tender ribbons, the rice absorbs all the savory tomato goodness, and the cheese bakes into a golden, bubbly blanket on top.

It is perfect for busy weeknights, potlucks, or any time you need a hearty, crowd-pleasing meal. Serve it with a crisp salad and some crusty bread, and watch everyone at the table go back for seconds.

Ingredients

1½ pounds ground beef
1½ cups uncooked white rice
4 large bell peppers (any color), cored and diced into bite-sized pieces
1 can (15 ounces) diced tomatoes, undrained
1 can (15 ounces) tomato sauce
1 cup low-sodium beef broth
1 medium yellow onion, diced
3 cloves garlic, minced
2 cups shredded cheddar or mozzarella cheese
1 tablespoon olive oil
1 teaspoon dried oregano
1 teaspoon dried basil
Salt and black pepper, to taste

Directions

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
In a large skillet over medium-high heat, cook the ground beef until browned and crumbled. Drain off excess grease and set aside.
In the same skillet, heat the olive oil. Sauté the onion, garlic, and diced bell peppers for 5 to 7 minutes, until softened and fragrant.
Return the beef to the skillet. Stir in the uncooked rice, diced tomatoes, tomato sauce, beef broth, oregano, basil, salt, and pepper. Bring to a gentle simmer.
Pour the mixture into the prepared baking dish and spread it into an even layer. Cover tightly with aluminum foil.
Bake for 45 minutes, until the rice is tender and most of the liquid is absorbed.
Remove the foil and sprinkle the shredded cheese over the top. Return to the oven and bake uncovered for another 10 to 15 minutes, until the cheese is melted and bubbly.
Let rest for 5 to 10 minutes before serving.

Variations

Turkey Version: Swap the ground beef for ground turkey for a lighter take.
Spicy Kick: Use hot diced tomatoes or add a diced jalapeño with the peppers.
Italian Twist: Add 1 cup of marinara sauce and use Italian sausage instead of beef, then top with mozzarella and Parmesan.
Mexican Style: Use taco seasoning, black beans, and corn, then top with pepper jack and cilantro.
Vegetarian: Omit the meat and add 2 cups of cooked lentils or a can of chickpeas.
Gluten-Free: This recipe is naturally gluten-free as written, just verify your broth and seasonings.

Expert Tips

Don’t precook the rice: The rice cooks right in the oven as it absorbs the tomato sauce and broth, which gives it incredible flavor.
Keep it covered: The foil traps steam and ensures the rice cooks evenly without drying out.
Check the rice: If it is still firm after 45 minutes, add a splash more broth, re-cover, and bake for another 10 minutes.
Use freshly shredded cheese: It melts more smoothly than pre-shredded.
Let it rest: Resting allows the casserole to set, making it easier to serve clean portions.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently in the microwave or in a 350°F oven with a splash of broth or water to loosen. This casserole freezes well for up to 3 months. Thaw overnight in the refrigerator before reheating.

Frequently Asked Questions
