This casserole is one of my go-to recipes. It’s a perfect meal: easy, nutritious, and satisfying.
We love stuffed peppers. Okay, actually we like stuffed anything. There’s just something kind of cool about stuffing all contained in a neat little package. I kind of go crazy over stuffed butternut squash. It’s so good!
But, I’ll admit, it can be a little bit of a hassle to stuff stuff (ha, get it?). There’s usually a fair amount of prep work involved. For stuffed peppers, you have to blanch the peppers first, drain them, prepare the stuffing, and then carefully put the stuffing into the peppers before you finally “stuff” them in the oven.
That’s the beauty of this stuffed pepper casserole. It’s a deconstructed stuffed pepper. The only prep work you have to do is brown the meat and onions. You don’t even have to cook the rice. Just dump everything in a baking dish, cover it and let it bake.
You’ll get all the deliciousness of stuffed peppers hassle-free. And that’s why this recipe is one of my weekday go-to recipes. Because hassle-free is good, right?
Hearty, nutritious, low-calorie, gluten-free, and easy to make, stuffed pepper casserole is a winner for sure!
About This Recipe
This casserole can be prepped in about 15 minutes but it needs to bake for at least an hour and a half, mostly hands off.
That might sound like a long baking time but the beauty of it is you can do anything you want while it bakes. Make a side salad. Sit down, relax! Catch up on emails. Play with your kids. Do some yard work. Whatever you want. Dinner will be ready when you are.
You probably should stick around the house since the oven is on but other than that you can do whatever your heart desires.
I’ll get you started on the recipe here and talk about some variations you can make.

What You’ll Need
- Ground Turkey: I like ground turkey because it’s leaner than ground beef. If you prefer a more traditional stuffed pepper flavor, use lean ground beef instead. Bulk sausage (either pork or turkey) can be substituted as well.
- Onion: It doesn’t really matter what type of onion you choose. For casseroles, a regular yellow cooking onion is just fine.
- Bell Peppers: Use any color you like or happen to have. A combination of two or more colors makes a colorful casserole.
- Crushed Tomatoes: Look for a large can of crushed tomatoes. The juicy tomatoes provide the liquid needed to cook the rice. If you only have diced tomatoes, use a large can (28 oz.) or two small cans. For best results, chop them in a food processor to break up the chunks. Stir in a couple of tablespoons of tomato paste.
- Rice: You’ll need a half cup of uncooked rice. While the recipe calls for brown rice which is more nutritious, feel free to substitute white rice. The casserole won’t take quite as long to bake.
- Dried Oregano: If you happen to have fresh oregano, feel free to substitute that. You’ll need to add more, about a tablespoon instead of a teaspoon. Dried Italian seasoning is a good substitute too.
- Garlic Powder: Garlic powder (not garlic salt!) adds subtle garlic flavor. If you’re a big garlic fan, feel free to increase the amount or use a couple of cloves of minced fresh garlic. Add it to the pan for the last minute or so, when you brown the meat and onions.
- Cheese: Sharp cheddar provides plenty of tangy bold flavor which allows you to use less cheese in your casserole (less cheese = less calories). Feel free to use whatever type of cheese you happen to have on hand.
- Fresh Parsley, optional: Freshly chopped parsley as a garnish adds fresh herbal flavor and a bright pop of color to the casserole.
How To Make This Casserole
Let’s get started! Turn your oven on to preheat and spray a large baking dish with non-stick spray.
In a large skillet, brown the ground turkey and onions with a little salt and pepper, breaking up the large chunks of meat so it browns evenly. It will take about ten minutes or so.
Meanwhile, cut a couple of bell peppers into one inch chunks, more or less. No fancy knife work here, just cut them up into bite-sized pieces, discarding the seeds and stems.
Measure out a half-cup of uncooked rice and open the can of crushed tomatoes. When the meat and onions are ready, put them into the prepared baking dish along with the rice, tomatoes, oregano, and garlic powder.
Stir well and cover the dish tightly with foil.
Note: It’s important to cover the dish because you want to trap the steam inside so that the rice cooks. It’s just like steaming rice on the stovetop in a covered saucepan.
After an hour and fifteen minutes, remove the foil and stir the casserole. Carefully put the foil back on and bake for another fifteen minutes or until the rice is tender. Sometimes it takes a bit longer.
Remove the dish from the oven, uncover it, and sprinkle on the shredded cheese. Put it back in the oven for five minutes or so, or until the cheese melts. Let the casserole set for 10 minutes or so to settle before serving. Garnish it with fresh parsley.
Normally, bell peppers are blanched (immersed briefly in boiling water) before stuffing them so that they are tender enough to cut into easily. The beauty of this stuffed pepper casserole is that the peppers do not need to be blanched. Simply cut the bell peppers into bite-sized pieces and cook them along with everything else. They’ll be perfectly tender.
Yes! If you have an abundance of bell peppers, cut them into bite-sized pieces and freeze them in freezer safe containers for up to four months, to use later in casseroles, soups, stews, or other cooked recipes. This is a perfect idea if you’re wondering what to do with lots of peppers!
Make It Your Own
There are lots of ways to make this stuffed pepper casserole your very own creation. Use what you like best or what you happen to have in your fridge.
- Substitute long grain white rice for the brown rice.
- Use lean ground beef or bulk sausage (pork or turkey) instead of ground turkey. Mexican chorizo is a good option, too.
- Vegetarian: Omit meat and substitute pinto or black beans.
- Cheese: Use any type of shredded cheese or omit it if you want to make it non-dairy.
- Spicy: Poblano peppers can be substituted for the bell peppers.
- Don’t like bell peppers? Try Vegetarian Stuffed Portobello Mushrooms or Caprese Couscous Stuffed Tomatoes. Another favorite of ours is Pizza Stuffed Spaghetti Squash!
To get a head start on making this casserole, brown the meat and onions up to a day ahead of time. Prep the peppers and shred the cheese. You’ll save about 15 minutes prep time.
The casserole can also be baked, cooled, and frozen for up to one month. Cover tightly and thaw overnight in the fridge before reheating. Bake at 350°F for 20-30 minutes or until heated through.
Storage & Reheating Tips
Leftover casserole can be stored in the fridge for up to three days. Reheat in the microwave or oven until heated through.
