How long does it last?

Stuffed Bell Pepper Casserole will last in the fridge for up to 3 days. Transfer any leftovers to a airtight container or cover tightly with plastic wrap. Store in the fridge.

To reheat, warm the casserole in a skillet on the stove top, or in the microwave. Heat in intervals until warmed through.

You can also reheat in the oven. Place original casserole and dish in the oven at 350F. Top with more cheese and cook until cheese is melted and the middle is hot.

If your stuffed pepper casserole seems a little dry, add some extra broth and stir before reheating.

Can you freeze it?

Want to store your unstuffed pepper casserole for another busy day instead of eating it right away?

The best way is to make it according to the instructions, and before baking, place in an airtight container and freeze.

When you’re ready to make it, you can remove it from the freezer and thaw in the fridge overnight. Then, bake as directed. I would wait to add the cheese until after thawing.

What do I serve with stuffed bell pepper casserole?

Personally, I like to serve this by topping it with sour cream and parsley for garnish.

Pair it with a nice side salad and crusty bread to create a complete meal.

You can also roast some brussels sprouts or broccoli in olive oil to combine with this dish, if you’re looking for a side with a more mild flavor.

Best Casserole Tips

  • Want to stay on a low calorie or low carb diet? Switch out the rice in this recipe for cauliflower rice instead.
  • For a little spice, try topping with red pepper flakes at the same time that you add your cheese.
  • To cut down on cooking time, try using minute rice instead of long grain rice.
  • To make this a one pot meal, I highly recommend creating this recipe in a dutch oven. This allows you to make a one pot casserole, and cleaning up will be super easy.
  • For lower fat content, you can use ground turkey and pair it with a mozzarella cheese made with skim milk.
  • Make this in a slow cooker. Brown the ground beef and drain. Add to a crock pot and add in remaining ingredients. Cook on low for 3-4 hours or until rice is done.
