liz’s tips for stuffed pepper casserole
- Use freshly shredded cheese! The preshredded cheese has anti-caking agents on the cheese that prevent it from melting properly.
- Bake, then individually portion the leftovers for easy meal prep!

Substitutions
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.
Ground Beef: You can substitute ground beef with ground turkey or ground chicken, it will not be as flavorful, but it will work.
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.
Beef Broth: Broth, bone broth, and stock can all be used interchangeably in recipes. You can use chicken broth, beef broth, or vegetable broth in this recipe/interchangeably.
Mozzarella Cheese: Freshly grated mozzarella is best. Pre-shredded cheeses can have additives that prevent them from melting well.
Low Salt: If you need lower sodium, omit salt from the recipe. Use low or no salt beef broth and tomatoes.
Extra Vegetables: You can add more veggies to this dish. I think raw or frozen green beans would be a nice addition, diced carrots or mushrooms would be great as well!
Stuffed Peppers: If you’re looking for a regular stuffed pepper recipe, check out our Classic Stuffed Peppers, Unstuffed Peppers, or Stuffed Pepper Soup.
Dairy Free: To make this recipe dairy free, omit the cheese or use dairy free cheese.
How to Make Stuffed Pepper Casserole
- Sauté garlic, onion, peppers, and beef in olive oil for 10 minutes.
- Pour in the tomato sauce, tomatoes, salt, black pepper, oregano, basil, rice, and beef broth. Stir to combine.
- Cover with an oven safe lid or aluminum foil and bake at 375° for 20 minutes.
- After 20 minutes remove the cover and add cheese. Bake for another 10 minutes.
- By this point all of the liquid should also be soaked up by the rice and you are ready to serve and enjoy!
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. Ground meat should always be browned before being added to a recipe for food safety. In addition to killing any bacteria, browning meat adds a ton of flavor to a dish.
How Long Do You Bake Stuffed Pepper Casserole? Stuffed pepper casserole should be baked at 375 for 20-30 minutes.
How do you know when bell pepper casserole is done? You’ll know that stuffed pepper casserole is done when the rice is fully cooked and the broth has been absorbed.
How to serve
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:
How to store
Refrigerator: This stuffed pepper casserole will last in the fridge in an airtight container for up to 4 days.
Freezing: We don’t recommend putting stuffed pepper casserole in the freezer. 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 to reheat Unstuffed Pepper Casserole
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.

I love how easy it is to put together and love all the ingredients; I added paprika and worcestershire sauce to it.
This was pretty good – I ended up adding a jar of salsa and opted out of the 8 oz tomato sauce for 15 ounce, I also added cabbage for an extra veggie!
I like this recipe very much. It never says when to put in the parsley.
Oops – thanks for pointing that out. It goes in with the other dried spices! Just updated that!
Wowza this was delicious! I made the Mexican chicken casserole the other night, which was good (we used it sort of as a dip for tortilla chips) but needs some tweaks so I was expecting the same for this recipe, but nope! It is great just the way it is! I did use ground turkey because beef is too expensive in my area and it was still great. I added extra cheese at the request of my family and broiled it to get it brown and bubbly and that made it extra good. Everyone was saying it tasted like a supreme pizza! They are already requesting that I make it again so this is for sure being added to the regular rotation.
A huge hit! I added Worcester sauce and crushed red pepper and extra garlic. Will make it again!
My teen boy loves when I make this, a house favorite and I make extra because he will take it for lunch too! Makes me feel good about getting good veggies and protein in for everyone.
So Delicious
Fantastic recipe!!! My husband and I loved it.. I really want to send kudos to you and your hubby because so far all 4 recipes I have made from your site have been a hit with my husband. He is a very picky eater and I cant thank you enough for creating these and making my life a whole heck of a lot easier. I highly recommend you! 🙂
Thank you so much, Kim! this seriously made my day. So glad you’re enjoying the recipes!
I’ve made a different variation of this in the past, but liked this one too – a little more simple than my other recipe.
Ma, added to my recipe file. My family said MAKE IT AGAIN.
And I will It was easy and cooked in no time.
Used brown minute rice, ground turkey, vegetable broth and a splash of wocestershire sauce. Yummy. Easy to make. Binus- hubby lived it. Also a generous portion for the calories
So glad you liked it!
Oh so so good! We’ll definately be having this meal again.
Just made this for dinner and it’s SO good! I followed the directions to the T. Didn’t have mozzarella but Colby but that’s the only thing different. I will definitely make this again 🙂
Delicious! I used rotel instead of regular diced tomatoes just to add a little spice. This will definitely be in the regular menu rotation
About the rice issue. I would make the casserole without the rice on top of the stove. Then cook your rice and put the casserole mixture on top. I do the semilar thing and pressuer can it serve it over rice.
Can I use a crock pot instead of my oven?
I’ve never tried that. I think the rice would come out mushy! It also would be more work. The point of the recipe is to start it in an oven safe skillet on the stove and then transfer to the oven so you only have one dish.
Whole family loved it !! I am loso diet since my OHS and I was able to make this and the flavor of the other spices was so good !! Highly recommend this and followed recipe completely!
Absolutely delicious and easy! My picky family loved it! 10/10!!!
I made this last night and it was delicious. I am going to pass this recipe
on to my kids (adults).
Thank you for sharing your healthy and delicious recipes!
This recipe sounds delicious! I will definitely try it this week 😊
Can I substitute Impossible ground beef or other meat substitutes (Boca crumbles?) in this recipe?
I haven’t tried it but other people have and have said it worked! Let me know if you try it!
This is one on my go to recipes. We LOVE IT. Hubby isn’t a fan of melted cheese so I don’t put the melted cheese on and sprinkle a little on mine and it melts on my plate. Could recommend this more!!
Has anyone made this in the crockpot? Thinking of browning the meat and onions and then letting the rest all cook together on low….
I think the rice might get overcooked, but let me know if you try it!
My hubby doesn’t like rice, so I substituted the rice for hashbrowns and omitted the beef broth.
We both loved it. It’s in my recipe rotation
