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!

      I haven’t tested it but you probably could and then adjust the cooking time some. Enjoy!

  1. Lauren says

    This recipe is so simple and delicious! My boyfriend and I love to make it and have given the recipe to our family who also rave about it! We found it best with the Amylu Andouille Chicken Sausage from Costco.

  2. Chelsey says

    I love your website Ashley! It has taught me to enjoy cooking again. I used to avoid cooking because I hate the mess! All of your recipes are delicious and I love the quick cleanup. This recipe is one of my favourites. We also love your orzo recipes. Thanks for what you do!

  3. Kimberly says

    Made tonight for dinner – super easy to make! Both myself and the hubs enjoyed it! Added in some zucchini and used ground turkey.

  4. Payton Y. says

    Would this meal be freezable after preparing?? I make this often and would love to make a couple ahead of time to freeze for easy postpartum meals. Maybe just wait to add the shredded cheese until serving?

    • The Recipe Rebel says

      Hi Payton, yes! 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 and reheat in a 250-300 degree oven for 20 minutes or until heated through. Enjoy!

  5. Reese says

    Super easy skillet perfect for meal prep. I added chili powder which gave it more of a taco vibe! I’ll be making it again!

  6. Bailey says

    My husband and I LOVE this recipe. We’ve made it several times and still keep coming back for more. It’s excellent comfort food!

  7. Kim says

    I have hatch chili sausage with monterey cheese. Do you think it would taste ok if I used this in the dish? Thanks!

    • The Recipe Rebel says

      Hi Kim! No idea, I haven’t tried it myself so it would be hard for me to say. If you decide to experiment, I’d love to know how it goes!

  8. Leslie says

    I made this for the first time last night and it was a huge hit. I printed out your recipe and it went straight into my “go to recipes” binder. I doubled the recipe to have leftovers. I didn’t have enough regular salsa but had avocado salsa on hand. So, I used a cup of that with a cup of regular salsa and it was very flavorful!

  9. Alyssa says

    Hi there!

    In your notes you wrote to “increase the broth to 2 cups” if you use brown rice but the recipe already has 2 cups of broth with white rice. Did you mean to increase it “by” 2 cups (to 4 cups)?

    Thank you!

    • The Recipe Rebel says

      Hi Alyssa! That was a typo, I would say 2 cups liquid to 1 cup rice would be enough for brown rice too. I would stick with 2 cups, but it may need to cook longer. Hope this helps!

      • Melissa says

        Tried this recipe and it was a huge hit. Already bought the stuff to make it again but I’m trying it with beef this time instead of sausage.

  10. Racheal says

    Just came here to say…I have made this soooo many times and it NEVER fails to please a crowd! So easy and soooo good!
