While I’m calling this a stuffed pepper casserole, it’s more of a deconstructed stuffed pepper dish. Yep, there’s no stuffing needed! Instead of stuffing the filling into the peppers, the bell peppers here are sliced, sautéed, then mixed with the other ingredients.  So technically, I guess this should be called an unstuffed pepper casserole with the flavors of its kissin’ cousin classic stuffed peppers.

Here are all the reasons why I loved this stuffed pepper casserole:

  • It takes just one pot and one casserole dish to make this casserole. You can even cook the rice in the same skillet to save time.
  • It’s so quick and easy to make. All you have to do is cook the ingredients in a skillet, let it simmer, and then cook for 20 minutes. This dish makes the perfect weeknight meal, as it’s prepped, cooked, and ready to eat in about 45 minutes.
  • This casserole is gluten-free and can easily be vegetarian with a couple of switches. Just substitute the ground meat for tofu, a can of white beans, or your favorite meat substitute, and don’t sprinkle with cheese.

Are you now convinced to try this stuffed pepper casserole instead of traditional stuffed peppers? Let’s get cooking!

    I substituted with things I had on hand from my pantry. A 10 oz. can of mild red enchilada sauce instead of tomato soup, sweet banana peppers from my garden instead of green peppers, a package of uncle Ben’s jasmine ready rice, 1-2 tablespoons taco seasoning sprinkled on the cooked ground beef. It was very easy and good.

  2. I think it sounds delicious , husband doesn’t do onions or bell peppers . Any ideas on substitutions for these ? Always looking for new casserole dishes for weeknight dinners !

  3. I love this recipe and my only change is using riced cauliflower instead of rice since I am try to cut back on carbs. Thanks for all your great recipes

    I’ve made this recipe as written and we love it, but I’ve also taken the lazy way out and used a bag of frozen pepper and onion blend. You can buy a bag of just pepper strips and still use a diced onion, or just get the bag of pepper and onion strips. It’s much easier and quicker. I also use jarred sauce.
