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
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!

Stuffed pepper casserole
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.
- Cook rice
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.
- Add ingredients
Add all other ingredients like salt and pepper, Italian seasonings if you like, spaghetti sauce etc. into the pot EXCEPT the cooked white rice and cheese. Stir to combine everything, reduce heat and simmer for about 5 minutes until it reaches a slow boil.
Turn heat off and stir in 1 cup of your cheese and your cooked rice.
You can serve at this time, or bake in the oven with more cheese.
Spray a 9×12″ dish with non stick spray and spoon mixture in.
Put in oven at 350 degrees for 30 minutes. Then top with 1/2 cup to 1 cup of mozzarella or cheddar cheese and put back in for 5 minutes. Serve!
