How to Make Easy Stuffed Pepper Casserole Recipe

Enjoy this simple way of making your favorite meal in the form of a stuffed bell pepper casserole recipe!

STEP 1 | Get started with recipe prep

Begin by washing and chopping all of the recipe ingredients. Then, add the ground beef, onion, and garlic cloves to a large pot over medium heat.

STEP 2 | Cook the ground beef

Next, cook the ingredients for about 7 minutes until the meat is cooked through, draining the excess fat and grease from the pot.

STEP 3 | Add the seasonings

Now, add the tomato paste, Italian seasoning, oregano, cumin, paprika, salt, and black pepper, and cook for 3 minutes while constantly stirring. 

STEP 4 | Cook with peppers, broth, and tomatoes 

Then, mix in the spinach, red, yellow, and green bell peppers, beef broth, and tomatoes, turn the burner to medium-low, and simmer the ingredients for 8-10 minutes or until the peppers are softer, stirring occasionally.

STEP 5 | Add remaining ingredients and taste

Add the cooked rice and cheese to the pot, mixing until combined. Then, taste to see if more salt is needed.

STEP 6 | Garnish and serve!

Finally, remove the pot from the stovetop, sprinkle with more cheese and cilantro, and enjoy!

Variations and Substitutions

• Spicy Stuffed Pepper Casserole. Add red pepper flakes, chili powder, or your favorite hot sauce to kick up the heat in this recipe.
• More Tomato Flavor. Include tomato paste for a more robust tomato flavor.
• If preferred, replace the cilantro with fresh parsley.
• Instead of ground beef, feel free to use ground turkey or ground chicken.
• Use your preference of white or brown rice for this easy recipe.
• If you’re not a fan of either green, yellow, or red bell pepper, use whichever variety is your favorite. 
• Instead of petite diced tomatoes, use regular diced tomatoes or a can of fire-roasted tomatoes.
• Monterey jack shredded cheese also works for this yummy casserole.

Storage and Reheating Tips

• Store the leftover casserole in an airtight container for up to 5 days in the fridge.
• I don’t suggest freezing rice dishes because the consistency of the rice, when thawed out, is a bit too soft. If you left the rice out, you could freeze the dish and add the rice before serving.
