Do you have to pre-cook the meat for the stuffed pepper casserole recipe? Yes, you need to pre-cook the meat for the stuffed pepper casserole.

Substitutions for Stuffed Bell Pepper Casserole
What are the best peppers for this recipe? Bell peppers are the best peppers for this recipe. Any color will work. Red, orange and yellow are all sweeter, but green bell peppers have a more mild flavor.
Tomato Sauce/Petite Diced Tomatoes: We wouldn’t recommend omitting tomato sauce or petite diced tomatoes. Both are necessary for the recipe. Regular diced tomatoes will work, we just prefer the smaller ones.
Minute Rice: If you don’t have minute rice, you can use brown rice. Use 2 cups cooked brown rice and reduce the amount of beef broth to only a 1/2 cup. We have not tried regular cooked or raw white rice and wouldn’t recommend it. We do not recommend swapping the rice with cauliflower rice. If you need a grain free recipe try our Whole30 Stuffed Peppers.
Extra Vegetables: You can add more veggies to this dish. I think raw or frozen green beans would be a nice addition or diced carrots.
Dairy Free: To make this recipe dairy free, omit the cheese or use dairy free cheese.
What Sides to Eat with Stuffed Peppers Casserole?
This stuffed pepper casserole is a complete meal in itself! You can serve more veggies on the side. Here are some of our favorite veggie side dishes:
- Garlic Brussels Sprouts
- Grilled Vegetables
- Honey Thyme Garlic Carrots
- Green Beans Almondine
- Lemon Parmesan Roasted Asparagus
How to store stuffed pepper casserole
Refrigerator: This stuffed pepper casserole will last in the refrigerator in an airtight container for up to 4 days.
Freezing: We don’t recommend freezing this stuffed pepper casserole. We tried it and the rice and peppers got very soggy/mushy, so we wouldn’t recommend it.
Make Ahead: You can make this stuffed pepper casserole ahead of time. We would recommend completely cooking it, letting it cool, and then reheating it when ready to eat. We don’t recommend mixing together the ingredients ahead of time and letting them sit overnight before baking as the rice can absorb the broth and create an odd texture.
How do you reheat stuffed pepper casserole recipe?
The best way to reheat stuffed pepper casserole is in the microwave for about 1-2 minutes. You can also sauté it in a pan on the stove until warmed through.
