Easy as can be! This stuffed pepper casserole recipe takes the classic flavors and ingredients of stuffed green peppers, then turns them into a cheesy comfort food dish that is irresistible.

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.
