Ingredients Needed

• Lean ground beef – Substitute for ground turkey or ground chicken for a healthier option.
• Sweet onion – If you can’t find sweet onions, you can use yellow onion as well. 
• Yellow bell pepper – Individual bell peppers can be swapped for any other color, like red or green peppers. 
• Red bell pepper – Replace with green bell peppers or yellow bell peppers as needed. 
• Italian seasoning – You can make your own italian style seasonings at home if you can’t find any at the store.
• Minced garlic – Replace with garlic powder as needed.
• Diced tomatoes with peppers and onions – For added spice, substitute for diced tomatoes with green chilies or Rotel.
• Tomato sauce – If you don’t have tomato sauce, you can swap with tomato paste.
• Long grain white rice – You can also use brown rice if you prefer. 
• Beef broth – No beef broth? Swap for chicken broth or vegetable broth instead. 
• Mozzarella cheese – For cheese, you can use pepper jack cheese, Monterey jack, or cheddar cheese as well.
• Pantry staples – Kosher salt, black pepper, Worcestershire sauce, fresh parsley for garnish.

How To Make Stuffed Bell Pepper Casserole

1. Preheat oven to 350F. In a large skillet or dutch oven, cook ground beef, onions, and bell peppers over medium-high heat to until beef is cooked thoroughly and veggies soften.
2. Add garlic, Italian seasoning, salt, and pepper. Stir with wooden spoon, cooking for 2-3 minutes.

3. Add in tomatoes, tomato sauce, Worcestershire sauce, and broth. Bring to a boil. Stir in uncooked rice.
4. Cover dutch oven or transfer vegetable and meat mixture into casserole dish or large pan. Cover baking dish with aluminum foil.

5. Cook for 30 minutes or until rice is tender, stirring halfway through. Remove from oven. Remove the foil and sprinkle with cheese.
6. Return to oven for a baking time of roughly 3-5 minutes until cheese is melted. Remove from oven and let cool. Garnish with parsley and serve.

How long does it last?

Stuffed Bell Pepper Casserole will last in the fridge for up to 3 days. Transfer any leftovers to a airtight container or cover tightly with plastic wrap. Store in the fridge.

To reheat, warm the casserole in a skillet on the stove top, or in the microwave. Heat in intervals until warmed through.

You can also reheat in the oven. Place original casserole and dish in the oven at 350F. Top with more cheese and cook until cheese is melted and the middle is hot.

If your stuffed pepper casserole seems a little dry, add some extra broth and stir before reheating. 

Can you freeze it?

Want to store your unstuffed pepper casserole for another busy day instead of eating it right away?

The best way is to make it according to the instructions, and before baking, place in an airtight container and freeze.

When you’re ready to make it, you can remove it from the freezer and thaw in the fridge overnight. Then, bake as directed. I would wait to add the cheese until after thawing.

What do I serve with stuffed bell pepper casserole?

Personally, I like to serve this by topping it with sour cream and parsley for garnish.

Pair it with a nice side salad and crusty bread to create a complete meal.

You can also roast some brussels sprouts or broccoli in olive oil to combine with this dish, if you’re looking for a side with a more mild flavor.

Best Casserole Tips

• Want to stay on a low calorie or low carb diet? Switch out the rice in this recipe for cauliflower rice instead.
• For a little spice, try topping with red pepper flakes at the same time that you add your cheese.
• To cut down on cooking time, try using minute rice instead of long grain rice.
• To make this a one pot meal, I highly recommend creating this recipe in a dutch oven. This allows you to make a one pot casserole, and cleaning up will be super easy.
• For lower fat content, you can use ground turkey and pair it with a mozzarella cheese made with skim milk.
• Make this in a slow cooker. Brown the ground beef and drain. Add to a crock pot and add in remaining ingredients. Cook on low for 3-4 hours or until rice is done.
