The Best Stuffed Pepper Casserole Recipe

This Stuffed Pepper Casserole recipe is based on my Mom’s famous peppers! Growing up one of my Mother’s favorite meals to make was stuffed peppers.  Whenever I go back to visit my Dad I always ask him to think of a meal or two he wants me to make and he always requests Mom’s Stuffed Peppers. 

What isn’t there to love about stuffed peppers?  Fresh peppers, meat, tomato sauce, rice – all smothered in melted mozzarella cheese?   Yes, please!

Here’s a video I made to show you just how quick and easy this recipe is to make!

The Ingredients

1. ground beef
2. minced garlic
3. chopped onion
4. green peppers
5. spinach
6. diced tomatoes
7. tomato sauce
8. beef broth
9. white rice
10. Worcestershire sauce
11. salt
12. pepper
13. mozzarella cheese

Directions to Make Stuffed Pepper Casserole

Brown your ground beef, along with 2 cloves of garlic and onion in a large frying pan until beef is browned.

Add the ground beef mixture into a baking dish. Both 11×8 and 9×9 size baking dishes work well for this recipe.

Add chopped green peppers, spinach, diced tomatoes, tomato sauce, beef broth, uncooked long grain rice, Worcestershire sauce, salt and pepper on top of the beef.

About the spinach, I add this because I think it’s a sneaky way to get my family to eat more vegetables and no one ever seems to notice it (including my 3-year-old who is always for ways to disagree with me). If you’re completely against spinach though, or you just don’t have it in your fridge, you can skip it.

Mix to fully combine the casserole.

Bake for 75 minutes, or until the rice is soft. Depending on the brand and variety of rice you use, sometimes you need 10-20 minutes more, so make sure to test it.

Remove from oven, sprinkle shredded mozzarella cheese on top and bake 5 more minutes or until the cheese is melted.

Serve and enjoy this Stuffed Pepper Casserole!

How to Make It More Healthy

Overall, this Stuffed Pepper Casserole is a pretty healthy meal at 380 calories per serving. Here’s some more ways to make it even more healthy:

• Substitute cauliflower rice if you’re worried about the carbs from regular rice. 
•  Add more vegetables if you’d like, like extra spinach or even some diced carrots!
• Swap the ground beef for ground turkey or ground chicken instead.
• Skip the cheese at the end, or only use 1/2 cup.

Can I freeze stuffed pepper casserole?

Yes you can freeze stuffed pepper casserole! 

First bake the casserole as instructed, skipping the cheese on top. After it’s cooked, allow to cool and then wrap in aluminum foil and place in freezer.  

Thaw it overnight in the refrigerator when you’re ready to bake it. Bake at 350 degrees F for about 60 minutes. During the last 5 minutes add the shredded mozzarella cheese on top.
