Stuffed Pepper Casserole is the perfect choice when you’re craving the savory flavors of stuffed peppers, but don’t have the time to get fancy. Made in just one large skillet, packed with ground beef, rice, tomatoes, and cheese, and ready in under an hour, unstuffed peppers will be a new family favorite.
We are big fans of stuffed peppers in my house. I have Mexican Stuffed Peppers, Italian Stuffed Peppers, and Stuffed Poblano Peppers on a regular rotation here, and when it’s really cold and gloomy outside, I love making a big pot of Stuffed Pepper Soup.
And while I love the flavors of roasted bell peppers stuffed with meat, cheese, and rice, the method for making them can be a bit finicky and time-consuming.
That’s where this easy recipe for Stuffed Pepper Casserole comes in! Instead of stuffing meat and rice filling into the peppers, we’ll just chop the peppers up and mix them in with the filling. It’s all baked together and topped with plenty of cheese to make a delicious and satisfying meal.
I made this tonight for dinner and oh my is this yummy. I am looking forward to making it again. I have tried many unstuffed pepper recipes and this one is the best I have made. Thank you!

Ingredients In Stuffed Pepper Casserole
Everything that you’d mix into a traditional stuffed peppers recipe is included in this delicious casserole:
Complete list of ingredients and amounts can be found in the recipe card below.
- Meat: Lean ground beef is my go-to when making stuffed pepper casserole, but you can also use ground turkey here.
- Veggies: You will of course need bell peppers! I like to use one red and one green. It adds some color variation and the flavors are slightly different. You’ll also need an onion, and three cloves of garlic.
- Seasoning: You have options when it comes to seasoning your casserole. Italian seasoning is the classic option, but cajun seasoning or taco seasoning are delicious too. I used cajun seasoning when I took the photos here, and the result had a lovely bit of spice to it!
- Canned Tomatoes and Beef Broth: These ingredients do double-duty here by creating the liquid needed to cook the rice, and adding tons of savory flavor.
- Rice: This recipe will work with any type of long-grain white rice. You don’t need to cook the rice separately, it will cook in the oven! I do recommend that you rinse your rice before cooking it.
- Cheese: Any good casserole will have a nice layer of melty cheese on top, and this one is no exception. I use a mixture of shredded mozzarella and shredded cheddar cheese. You can use one or the other or include any bits of cheese you have to use from your fridge.
- Plus: Salt, Pepper, Olive oil for cooking, and chopped parsley to garnish the final dish.
How To Make Stuffed Pepper Casserole
- Get Started: Preheat the oven to 350°F/180°C. In a pan, or in a heat-resistant skillet over medium-high heat and heat olive oil, and add ground beef.
- Cook the Meat and Veggies: Saute, breaking the meat up with a spatula until it’s no longer pink. Drain away the fat, then add the diced peppers and onions to the pan. Cook for 2-3 minutes until the veggies start to soften. (they will cook fully while the casserole bakes)
- Add Seasonings: Add the garlic, seasoning, Worcestershire sauce, salt, and pepper to the pan. Cook for 30 seconds, then stir in the diced tomatoes.
- Add Rice: Stir in the rice and the beef broth. Bring to a boil, then cover with a lid, or foil if your pan doesn’t have a lid.
- Bake: Place the covered casserole in the oven and bake for 20-25 minutes, or until the rice is cooked. You can taste the casserole and see if there’s any crunch. If there is, put it back in the oven for a few minutes. You can add a splash of broth or water if you think it’s needed too.
- Add Cheese: Top the stuffed pepper casserole with shredded cheese, and set the oven to broil.
- Broil: Place the dish under the broiler for 3-5 minutes, or until the cheese is melted and bubbly.
Tip!
To make this a true one-pan meal, use an oven-proof skillet that is about 12-inches across to make this recipe, or use a regular frying pan, and then transfer the mixture into a 3.5 quart casserole dish, or a 13×9-inch baking pan to bake.
I’m using this red enameled cast iron braiser from Le Cruset, or you may want to look into this more economical option from Lodge.
Recipe Tips and Variations
- To Add Extra Flavor, use fire-roasted tomatoes or Rotel tomatoes with green chilies instead of plain diced tomatoes.
- You Can Also Add Sausage, or a blend of ground beef and sausage to get even more flavor. Italian sausage is delicious in unstuffed peppers.
- Don’t Forget to Rinse! White rice should be washed before cooking. There’s no need to soak it, just add it to a fine mesh sieve and rinse away any impurities. Rinsing also reduces the amount of starch in the rice, so it will cook up fluffy rather than sticky.
- The Rice May Need Extra Time, so be sure to test it at the end of the 20 minutes. If it’s still a bit crunchy, you can add a splash of water or broth and put it back in the oven for 5 minutes until it’s done.
Storing Tips
To Store: Keep leftovers in an airtight container in the fridge. Stuffed pepper casserole will stay fresh for up to 4 days.
To Reheat: Use the microwave to reheat the casserole quickly, or add servings to a pot and heat over medium-low heat until warmed through.
To Freeze: This casserole can be frozen for up to 3 months. Either freeze the whole thing after baking, or freeze individual servings in freezer containers. Let thaw overnight before reheating.
What To Serve With Stuffed Pepper Casserole
This meaty casserole is filling, satisfying, and has all the food groups in it already, so feel free to serve Stuffed Pepper Casserole as the singular main dish for dinner.
To add something extra to the meal, make a tasty and healthy salad, like my Beet Salad with feta and apples, or a classic wedge salad, and serve that as your first course.
Homemade dinner rolls or a batch of easy garlic bread will also be delicious here!
FAQs
You can prep half of the casserole recipe ahead of time to make dinner come together more quickly. Cook the ground beef and then follow the recipe through step three, where we add the canned tomatoes. Let the meat mixture cool, and then store it in the fridge until you’re ready to make dinner. You’ll just need to heat the mixture on the stove and then continue the recipe from there!
If you don’t have any Worchestershire, feel free to use soy sauce or tamari instead. Each of these gives a kick of umami flavor that makes the casserole delicious.
The amount of liquid and cooking time in this recipe for unstuffed peppers is correct for making the casserole with long-grain white rice, and I did not test it with brown rice. If you want to make it with brown rice instead, you will need to take steps to ensure that it cooks correctly. Brown rice takes longer to cook and will absorb more liquid. I suggest baking the casserole for at least 30 minutes total and adding an additional ¾ – 1 cup of broth to the mixture.
You might never stuff an actual pepper again once you realize how delicious and easy this stuffed pepper casserole is! Have fun experimenting with different seasonings, and be sure to Pin the recipe so you can easily find it again.

Stuffed Pepper Casserole
Equipment
- 3.5 quart Oven proof skillet/casserole pan
Ingredients
- 2 tablespoons olive oil
- 1 ½ pounds ground beef lean
- 1 yellow onion diced
- 1 medium red bell pepper diced
- 1 medium green bell pepper diced
- 3 small cloves garlic minced
- 1 teaspoon Italian seasoning or cajun seasoning
- 2 teaspoons Worcestershire sauce
- ½ teaspoon salt
- ¼ teaspoon ground black pepper
- 14 ounces canned diced tomatoes
- 1 cup long grain white rice
- 1 ½ cups beef broth
- 1 ½ cups shredded cheese cheddar, mozzarella, or both
- parsley for garnish
Instructions
- Preheat the oven to 350°F/180°C. In a pan, or in a heat resistant skillet over medium-high heat and heat olive oil, and add ground beef.
- Saute while breaking it with a spatula until it’s no longer pink. Drain the fat, then add the onion, and bell peppers. Cook for 2-3 minutes.
- Add garlic, seasoning, worcestershire sauce, salt, and pepper. And cook for 30 seconds. Add diced tomatoes and stir it in.
- Add rice, and beef broth. Stir and bring to a boil, then cover with a lid (or foil if using a casserole dish that doesn’t have a lid).
- Place in the oven for 20-25 minutes. It’s ready to be removed when the rice is cooked through (I try the rice and see if it still has a crunch). If not, return to the oven and add a splash of water IF necessary.
- Remove from the oven, and sprinkle with cheese.
- Then return to the oven and place under the broiler for 3-5 minutes or until the cheese has melted and bubbly. Garnish with fresh parsley and serve.
Notes:
- If you choose an oven-proof skillet, you can make this entire meal in the same pan! Otherwise, transfer the mixture to a shallow 3.5-quart casserole dish (a 9×13-inch Pryex works well) before baking.
- Add additional flavor by using fire-roasted diced tomatoes or Rotel in place of regular diced tomatoes.
- Instead of ground beef, or in place of some of it, use ground turkey or ground Italian sausage.
- The Rice May Need Extra Time, so be sure to test it at the end of the 20 minutes. If it’s still a bit crunchy, you can add a splash of water or broth and put it back in the oven for 5 minutes until it’s done.
- To Store: Keep leftovers in an airtight container in the fridge. Stuffed pepper casserole will stay fresh for up to 4 days.

nothing like the pictures followed exactly..disappointed hubby who loves stuffed peppers and this is more of a soup even tried extra rice there just isn’t flavor or thickness here..
Little Sunny Kitchen says
Hi Lisa, if yours turned out like a soup, there may have been an issue with preparation. Many have tried this recipe and had wonderful results! I hope you’ll try again sometime.
Eve F says
This is a great recipe . The only change I made was to use fire roasted tomatoes in place of the plain ones, otherwise a keeper.
Little Sunny Kitchen says
I bet it was delicious with the fire roasted tomatoes! Thank you for the feedback!
Sarah Clarke says
Household favorite!
Little Sunny Kitchen says
Enjoy!
NANCY LIVERMORE says
Excellent, I used a 1/2 package of taco seasoning instead of the Italian seasoning and I also used poblano peppers. This was so tasty, leftovers tomorrow.
Little Sunny Kitchen says
What a great idea, changing up the flavors to a more tex-mex style. Sounds great!
Julie Such says
Made for a potluck, so easy and delicious. How is the prep time calculated? I took more than 10 to toss this together. Thanks for posting and I’m finding many good recipes on the site
Little Sunny Kitchen says
Thanks Julie! The prep time is the approximate amount of time I took to chop the veggies and prep the rest of the ingredients. The rest of the time in the recipe card is for the active cooking time.
