Stuffed Pepper Casserole Ingredients Needed:

ingredients needed for stuffed pepper casserole in bowls and plate.
  • Italian Sausage – Can be swapped with ground turkey, chicken or beef. Have some of this Crockpot Shredded Chicken to use up? It works perfectly in here!
  • Rice – You can use long grain brown rice instead of long grain white, you will increase the cook time to 30-45 minutes. This will depend on the kind of long grain rice you use — use the package directions as a guide.
  • Bell Peppers – You can use any color of bell peppers you like best. Red and green are my favorites to use in this casserole recipe.
  • Mozzarella – The way that this melts on top of the casserole is absolute perfection. Feel free to mix up the cheese depending on your tastes and what you have.
  • Onion – A white or yellow onion both work well.
  • Salsa – In a pinch, tomato sauce will also get the job done, but you may want to add extra seasoning.
  • Garlic – You can always add a little more if you’re a big garlic fan!
  • Seasonings – I use a simple but bold blend of oregano, cumin, salt and pepper.

How to make Stuffed Pepper Casserole

Take a quick look at just how easy this stuffed pepper casserole recipe is! For more info about ingredients and instructions, scroll to the bottom of this page where you’ll find the recipe card.

  • Cook the sausage. Then, mix in the peppers and onions. Cook until just softened.
  • Mix in the garlic and seasonings.
  • Pour broth into the pan.
  • Mix in the salsa and rice.
  • Stir everything together. Bring to a simmer, cover, lower the heat and let it cook for 15-20 minutes or until the rice is cooked.
  • Sprinkle with cheese, cover, and let the cheese melt.

Variations and Substitutions

  • Add extra veggies: Try mushrooms, finely chopped spinach, onions, or shredded carrots or zucchini! This recipe is a great one for tossing in those last few veggies that need to go before your grocery restock.
  • Spice it up: I rely on Italian sausage and prepared salsa to give this recipe a ton of flavor without needing any extra seasoning. You can always go ahead and add in extra herbs and spices if you prefer, or make it spicy with a pinch of cayenne or some crushed red peppers.

How to store Stuffed Pepper Casserole

Simply let the casserole cool slightly before covering tightly and refrigerating for up to 3 days. To reheat, add a splash of broth or water, cover and pop it in a 250-300°F oven for 15-20 minutes until heated through.

Can I freeze Stuffed Pepper Casserole?

Absolutely! To freeze, you can cook this casserole completely and let cool slightly before wrapping with plastic wrap and then foil (or a lid, but plastic wrap is always a good idea!). Freeze up to 3 months.

To serve, thaw overnight in the refrigerator, cover and reheat in a 250-300°F oven for 20 minutes or until heated through.

Serving suggestions:

This one pan recipe is a full meal all by itself! If you did want to pair it with anything, I recommend a veggie side dish like Air Fryer Broccoli or Cheesy Baked Asparagus or some of this Garlic Bread!

  • Stir in the salsa.
  • Rinse rice well under cold water and add to the skillet.
  • Stir well and bring to a simmer. Cover, reduce heat slightly, and simmer for 15-20 minutes until rice is cooked through. (*BAKE: You can also cover tightly and bake at 350 degrees F for 20-30 minutes until cooked through).

    Everyone LOVED it! I used ground beef and seasoned it w/ Italian seasoning, salt & pepper. I also used marinara sauce and minute rice and added a little shredded parmesan to the mozzarella. Will definitely add this to the dinner rotation!

  2. Robi Kott says

    Very good! We’re counting calories so I used ground chicken. I thought that may make it bland, so I added italian seasoning and fresh garlic. I also added sweet onion and some leftover mushrooms. This is much easier to make AND eat than stuffed peppers. We will definitely do this again!

  3. Caitlyn says

    Mmm, yummy recipe! I used ground pork with Italian seasoning instead of sausage. So good! Thanks for the recipe!

    PS. My mom loves your recipes too!

  4. Danielle says

    This recipe was so easy and delicious! We will be adding it to our weekly meal rotation! I added half a white onion as well.

  5. Debbie says

    Hi Ashley! If I make this today and refrigerate to use tomorrow, should I do anything differently to keep it from getting mushy or will it be fine?

    • The Recipe Rebel says

      Hi Debbie, To serve this casserole later, you can cook completely in an oven-safe skillet, then let cool slightly before covering tightly and refrigerating for up to 3 days. To heat, simply pop it in a 250-300 degree oven for 15-20 minutes until heated through. Hope you enjoy it!

  6. Laura says

    Wow! This is a fave & I make it for mealtrains too!

    Love the Italian sausage and salsa combo! So much flavor!!

    • The Recipe Rebel says

      Hi Jtet! I’ve only tested the recipe as written so can’t advise if using a different rice. If you decide to experiment, let me know how it goes!

  7. Lori says

    Can I put together the casserole uncooked and freeze it and then bake it when I need a quick meal or a meal to take to a friend? Thank you

  8. Pam Crider says

    Haven’t tried it yet, so I can’t rate it, but was wondering if anyone has made a keto version of this with riced cauliflower?

    • Ashley Fehr says

      Hi Danielle! Unfortunately brown rice takes considerably longer. There are tips and cook times for brown rice included in the handy tips above the recipe.

      • B says

        Your recipe calls for 2 cups of broth already with white rice, but then under the brown rice info you say to increase the broth to 2 cups if you do brown rice? But it was already 2 cups.

  9. Heather says

    Made this for dinner last night and it was a big hit! I used turkey meat so I added a little bit of taco seasoning to give it a little more flavor.

      • Liz says

        Hi! This looks excellent! Can I sub Jasmine rice or is brown rice preferred as the best substitute?

      • The Recipe Rebel says

        Hi Liz! I’d say yes, you could probably use jasmine rice. For brown rice it would take a lot longer to cook, so not sure how it would work. If you decide to experiment, I’d love to know how it goes!

  10. Sherri says

    This was amazing. I used the Italian sausage that is packaged like hamburger meat makes it so simple. I made ahead put in fridge and just reheated. Will definitely make again.

  11. Katie says

    This recipe was not only easy to make but delicious too. We used ground beef and salsa. We will definitely make this again. Thanks!

  12. Lori P. says

    Hi Ashley, This looks delicious. . . I’m eager to try this. Do you happen to have an instant pot version ? 😊

  13. Carol says

    Would love to try this recipe. Reminds me of Unstuffed Cabbage Rolls. In your story you say salsa, but the recipe calls for tomato sauce. Can either be used? Thanks.
