Stuffed Pepper Casserole
This cheesy casserole is a great easy going dinner, that has hardly any prep time (less than 20 minutes) with all the classic flavors of stuffed peppers, plus extra cheese on top! It’s perfect when you need an easy dinner that your whole family will ask for on repeat.
Stuffed Pepper Casserole Ingredients
- olive oil
- bell pepper : green peppers, red peppers, or any color
- yellow onion
- minced garlic
- ground beef : can substitute ground turkey
- Italian seasoning
- salt
- tomato sauce
- rice : can use your favorite cooked rice for this recipe, white rice, brown rice, basmati rice, jasmine rice, etc.
- mozzarella cheese : can substitute cheddar cheese, colby jack, or any of your favorite shredded cheese varieties.
How to Make Stuffed Bell Pepper Casserole
- Saute your olive oil, diced peppers, onions, and garlic in a large saute pan for a few minutes until the vegetables just start to get soft.
- Add in the ground meat and cook until the meat is cooked through. Drain out the grease.
- Add in the seasonings, salt, tomato sauce, rice, and 1/4 cup of the mozzarella. Stir it all together.
- Pour it into your baking dish. Cover the casserole dish with aluminum foil and bake until it is hot throughout. Remove the foil and let it cook for another few minutes until the cheese on top gets melted and golden.
- Let it sit for about 5 minutes, then serve hot!
How to Make Stuffed Peppers Casserole Ahead of Time
You can even freeze a fully made casserole, just before baking it as a great make ahead meal. Make two casserole dishes and eat one now, and save the other for next time. Wrap the baking pan first in plastic wrap, and then foil.
Let the casserole thaw in the fridge overnight, then bake it according to the recipe card directions. If it’s still a little frozen or too cold in the middle you may need to add about 5 to 10 minutes to the baking time. Just make sure the dish is hot throughout.
Stuffed Pepper Casserole Recipe Tips & Tricks
- Instead of ground beef, try substituting ground turkey, or half ground Italian sausage, half ground beef.
- Make this stuffed pepper casserole a low carb dish by using cauliflower rice instead of a regular grained rice.
- You can also make this casserole vegetarian, by leaving out the beef and adding more vegetables, or by adding 15 oz of drained beans, like white beans, black beans, etc.
- Add more vegetables to this dish, by sautéing them up with the diced pepper, and onions – try some mushrooms, or zucchini.
- This recipe does call for already cooked rice, I like to use my favorite minute rice, microwave rice packet, or some leftover rice from another meal to save time.
- Serve this easy casserole with more delicious vegetables, like roasted broccoli, or some yummy rolls, corn bread, or a side salad.
How to Store Bell Pepper Casserole
You can store leftovers in an airtight container in the fridge for up to 4 days. They’re easily reheated in the microwave until hot. It’s one of my favorite meals for eating all week long for lunch.
You can also store the leftovers in the freezer for up to 3 months. Cover them in a freezer safe container, or double wrap with plastic wrap and foil.
This stuffed pepper casserole is one of my favorite easy meals. It’s a family favorite that is the perfect all in one dish, and a delicious meal.

Easy prep. I used 2 cups of cooked brown basmati rice instead of three.
Made enough for leftovers for the two of us. Very flavorful and delicious!
Kirsten says
This was such a great recipe! Made it for my family and it was a huge hit!
Karen Carr says
I’m so glad I saw this! Never thought to make these a casserole & it’s the perfect answer for my family who doesn’t like the entire pepper. But they eat it cut up. Always great suggestions!
Beth says
When making this do you need to cook the rice first or just mix it together with the other ingredients.
Aimee says
The rice is cooked first, just however you want to cook it (instapot, minute rice, stove top, rice cooker, etc.)
Kathy Chalmers says
Made this recipe. Was unable to get can of tomato sauce. Was able to use pasta cooking sauce. Found it a bit too much tomato flavour. Added sour cream. Next time I am going to add mushrooms for some extra flavour.
Can you suggest what else to use for the tomato sauce that is available in Australia
Aimee says
I’ve found there is something in Australia called tomato passatta, that should work? Otherwise just diced or crushed tomatoes would work too. You could always cut the amount if it’s too tomatoey for what you prefer
Judy Davis says
When I copy and paste recipes I like to get as much information; just in case I pass it on to someone. Yes, I always list who did the recipe and their website.
