Stuffed Pepper Casserole Ingredients Needed:

• 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.

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!
