    A mixing bowl with rice and  Italian Sausage.
    1. In a large mixing bowl combine cooked Italian sausage and cooked white rice.
    Added sauteed yellow onion to the mixing bowl.

    2. Add sautéed diced yellow onion and mix together.

    Added variety of colored peppers to the mixture.

    Baked stuffed pepper casserole  ready to be eaten.

    6. Serve hot and enjoy this super simple Stuffed Pepper Casserole.

    Hint: This recipe doesn't ask you to cook the bell peppers before assembling. This keeps them fresher and crispier when you cook the whole casserole together. We aren't fans of soggy peppers over here!

    Substitutions

    • Ground turkey- Use ground turkey instead of Italian sausage for a healthy alternative.
    • Minute rice- In a pinch, because you cook the rice beforehand, minute rice works wonderfully with this recipe.
    • Cauliflower rice- At a 1:1 ratio, substitute cauliflower rice for the white rice for a vegetable heavy dish.
    • Quinoa- Looking for more protein? Use quinoa at a 1:1 ratio instead of rice.
    • Brown rice- We love brown rice! This recipe uses white rice, but brown rice can easily be used instead.
    • Cheddar- Have a thing for cheddar cheese? Use shredded cheddar cheese instead of mozzarella.

    Variations

    • Spicy - add a couple of chopped jalapeño peppers to spice this dish up!

    Equipment

    • Mixing bowl
    • 9x13 baking dish

    Storage

    Store leftover cooked casserole in an air tight container for 3-4 days in the refrigerator.

    This dish does not freeze well!

    Top tip

    We love making this dish when we have leftover rice in the fridge. It's an easy way to use up vegetables, and rice you are trying to eat up! It also makes a great meal prep meal!
