You will also need a dutch oven or skillet, 2-quart casserole dish, and broiler (oven setting).

How to Make the Best Stuffed Pepper Casserole

Brown the beef. In a 4 quart Dutch oven or large skillet, add ground beef and cook over medium high heat until no longer pink, about 5-7 minutes. Stir well and break up the beef into small pieces. Add onion and garlic. Stir well to combine and continue cooking for 3-4 minutes until tender.

Add the remaining ingredients. Add bell peppers, Italian seasoning, beef broth, canned tomatoes, tomato paste, and rice. Mix well and bring it to a boil. Reduce heat to low and cover the lid. Simmer until all the liquid has been absorbed and the rice is fully cooked, about 25 minutes.

Add parsley and cheese. Stir in parsley and ½ cup shredded cheese. Season with salt and pepper to taste.

Broil. Transfer the mixture into a 2 quart casserole pan and top with the remaining cup of cheese. Turn the broiler on HI and place into the oven until the melted cheese is golden brown, about 2 minutes. (You can also leave the mixture in the Dutch oven and top with cheese and cover the lid until the cheese is melted).
Garnish. Top with extra parsley, if desired, and serve warm.

Recipe Variations

Use green bell peppers. Although most regular stuffed peppers use red bell pepper, you can easily change things up and use green peppers for a slight flavor twist.
Make it vegetarian. Want to skip the meat? Use your favorite plant-based ground beef instead. You can also substitute with more veggies including sautéed mushrooms.
Adjust the seasonings. Experiment with different seasoning blends to change the flavor. This cheesy stuffed pepper casserole would taste lovely with Indian spices, like garam masala.
Add more veggies. If you find yourself running low on peppers, you could also add roasted mushrooms, eggplant, or zucchini for extra flavor and nutrients.
Make it spicy. Add some red pepper flakes or even cayenne pepper for extra heat and spice.

Recipe Tips and Tricks

Be flexible with your rice. No basmati rice? Look for long-grain white rice like jasmine rice. You can even use long-grain brown rice, but you may need slightly more broth and a longer cooking time.
Deglaze the pan. One trick you can do to add extra flavor to any dish is to deglaze the pan after sauteeing your onions and garlic. Add a splash of balsamic vinegar, and as it evaporates, it will leave a concentrated, umami flavor in the vegetables and beef.

FAQ

How do you reheat stuffed pepper casserole?

The easiest way to reheat this easy stuffed pepper casserole recipe is to microwave your serving for 1-2 minutes. It may benefit from a little extra moisture, so add a splash of chicken broth or water first. You can also sautee your leftovers in a large nonstick skillet on the stove or bake them in a small dish in your oven at 350 degrees F for 5-6 minutes.

Do you boil peppers for unstuffed peppers?

Although some stuffed pepper recipes call for boiling the peppers to remove any bitterness, that process is not necessary at all for unstuffed peppers. As the peppers cook, they will soften and absorb all the seasonings, tomato, and broth. It also helps you get dinner on the table quickly, too!

Can you make unstuffed peppers in a Dutch oven?

If you want an easy way to make stuffed pepper casserole, skip the baking dish and use a Dutch oven. You can cook everything right in the pot and even close the lid to melt the mozzarella cheese so it seeps into all the nooks and crannies. You can also cook everything in the pot and then transfer it to a baking dish under the broiler to melt the cheese, but that's just one more pot to clean up. For the easiest meal, cook the entire thing in your Dutch oven or large soup pot right on the stove!
