Unstuffed Peppers Casserole
When I married my husband he taught me how to make “his Grandma’s stuffed peppers” because he loved them so much. We all really liked them and it even got my daughters to really like bell peppers because of it.
- I still make them quite often but because I was on a casserole kick this month.
- I thought I should be able to create a sort of deconstructed bell pepper recipe in the form of a casserole….and here it is!!
It worked really well and I basically used the same ingredients in my original recipe to make it (with a few minor adjustments).
Like I said, everyone prefers a different level of seasoning and spice levels so adjust as you see fit before pouring it into your casserole dish to see if you want more, but this was perfect for our taste buds!
This is such a great recipe in fact it was featured by Country Living online with several other of their favorite dishes!
Stuffed Pepper Casserole
- Green peppers – use any colors you like
- Ground beef
- extra lean ground turkey would be fine
- Onion and garlic
- Diced tomatoes – I use petite
- Spaghetti sauce – or tomato sauce but spaghetti sauce lends to more flavor
- Uncooked rice
- white rice needs to be cooked before adding with other ingredients
- even cauliflower rice would probably be fine
- Mozzarella cheese
- Mushrooms
Spices listed below are just suggestions of course. Taste before adding into dish to see if you want to adjust.
In the video above I added tomato sauce, in the instructions below I swapped out for spaghetti sauce because it added even more flavor.
You can use either one but after a time or two we prefer spaghetti sauce if we have it on hand.
You basically precook everything but it all comes together when you pour it into your casserole dish and pop it in the oven. Everything melds together and the flavors really come out then.
Serve as is or with a side of salad or bread and you’re done!
If you have a pressure cooker we also made this Instant Pot stuffed pepper casserole you can try, there we did not precook the rice.
If you love this ground beef casserole you should try Crockpot stuffed bell peppers and:
- Our Mexican style enchilada lasagna casserole is delish
- For a lower carb meal, these zucchini noodles and shrimp are great
- Then give this slow cooker lasagna casserole recipe a whirl
- If you have a pressure cooker, try our Instant Pot crack chicken casserole for total comfort food on a fork.
Air fryer stuffed peppers are great, or make Instant Pot stuffed peppers.

Put olive oil in a large pot on medium heat. Add extra lean ground beef, diced green peppers and onions and simmer until they soften a bit and meat is browned.

On the stovetop or pressure cooker, put uncooked rice and water in and cook until tender. Long grain rice, white, or Instant Pot brown rice works quite well.

If using the mushrooms, should they be sauteed along with the beef, pepper and onions?

What is the purpose of cooking this in the oven at 350 for 30 minutes?Isn't everything already cooked?

Very good recipe..... but I would advice cutting down on the salt. 1 tsb salt, 1 tbls Seasoning Salt, 1 tsb Garlic Salt makes it too salty.
