You’ll need:

2 tablespoons of olive oil
½ cup of chopped onions
2 cups of diced bell peppers
1 pound of ground beef
1 teaspoon of salt
1 teaspoon of onion powder
1 teaspoon of minced onion
1 teaspoon of paprika (smoked or sweet paprika)
½ teaspoon of ground black pepper
2½ cups of beef broth
1 (14.5-ounce) can of petite diced tomatoes, not drained
2 tablespoons of tomato paste
1 cup of rice
2 cups of shredded mild cheddar cheese, divided in half

PRO TIP:

I like to freshly shred the cheese from a block as it melts easier. However, you can use any cheese mixture for this flavorful meal.

Stuffed Pepper Casserole Substitutions And Additions

GARLIC: You can substitute onion powder with garlic powder and minced onion with minced garlic in this easy casserole.

OIL: Instead of olive oil, you could also use vegetable oil.

ONIONS: Instead of sweet onions, you could also use yellow onion, white onion, or red onions. If you’d like a more mild flavor, try using shallots.

BEANS: You could add a can of black beans to make this even heartier.

TOMATOES: Instead of diced tomatoes, you can substitute with a can of Rotel diced tomatoes and green chilies. You could also use a can of fire-roasted tomatoes as well.

SPICE: Instead of paprika, add a pinch of cayenne or red pepper flakes, Italian seasoning, chili powder, or substitute ground pepper with lemon pepper seasoning. You could also add a dash of Worcestershire sauce or even soy sauce.

PEPPERS: Any combination of colors for the peppers will be fine in this great recipe as long as it adds up to two cups.

You can use a variety of red bell peppers, yellow bell peppers, and orange bell peppers or, add green bell peppers to the mix, or just use one color.

GROUND MEAT: Any ground meat that you would use in stuffed peppers would work for this recipe as well. Try ground pork, ground turkey, or ground chicken. You could also use a mild or spicy ground sausage. I prefer a lean ground beef.

BEEF BROTH: You can substitute the beef broth with one cube of beef bouillon and 2½ cups of hot water. You could also use vegetable stock or chicken broth.

RICE: I used long grain white rice, but you could substitute it with brown rice. Just keep in mind that the cooking time of the rice may vary. You could also make this low-carb and use cauliflower rice.

CHEESE: You can use your favorite cheese blend in this unstuffed bell pepper casserole. Try mozzarella cheese, Colby Jack, Monterey Jack, or Pepper Jack for a hint of spice.

How To Make This Unstuffed Pepper Casserole Recipe

This delicious casserole comes together quickly, all in one pan. First, the beef and veggies are sauteed before simmering the mixture with the rice to create the perfect texture.

Top everything with cheese and let it melt for a hearty and tasty dinner for a busy weeknight.

STEP ONE: In a large skillet, over medium heat, pour the olive oil and add the onions. Stir and cook for one to two minutes until the onions are nice and warm.

STEP TWO: Add the chopped peppers and keep cooking and stirring until they are warm (one to two minutes) and the onion starts to be translucent.

Don’t overcook the vegetables, as we want a slight crunch when serving.

STEP THREE: Add the ground beef, salt, onion powder, minced onion, paprika, and ground pepper.

STEP FOUR: Using a heat-proof spoon, over medium heat, break the meat into pieces and mix so the seasoning can spread throughout the mixture.

Keep cooking until the meat is fully cooked, with no more pink.

STEP FIVE: Pour in the beef broth, diced tomatoes, and tomato paste. Mix well.

STEP SEVEN: Bring to a simmer, cover, and cook for 20 to 25 minutes or until the rice is nice and tender.

OUR RECIPE DEVELOPER SAYS

I like to stir the mixture every five minutes so it does not stick to the bottom.

STEP EIGHT: Once the rice is cooked, sprinkle one cup of the shredded cheese. Mix well so the cheese can melt in the skillet.

This step is optional; if you are skipping this step, only use one cup of cheese in the ingredients.

STEP NINE: Sprinkle the remaining cheese on top. Cover and let the cheese melt.

PRO TIP:

Once you put the cheese on top, you can put it under the broiler for one or two minutes until the cheese is nice and golden for a different look and texture.

STEP TEN: Serve and enjoy!

PRO TIP:

When serving this dish, you can sprinkle some fresh herbs and additional cheese.
