Step-by-Step Cooking Instructions

Now that you have your ingredients and variations ready, it’s time to start cooking! Follow these easy, step-by-step instructions to create a mouthwatering Stuffed Pepper Casserole.

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). While the oven is heating, start prepping your ingredients.

Step 2: Cook the Ground Beef

In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the ground beef and cook for about 5-7 minutes, breaking it up with a spoon, until browned and fully cooked. Season with salt, pepper, and Italian seasoning. Remove from heat and drain any excess fat.

Step 3: Sauté the Vegetables

In the same skillet, add the diced onions, bell peppers, and minced garlic. Sauté for about 5 minutes until the vegetables become soft and fragrant.

Step 4: Combine Ingredients

Once the vegetables are softened, add the diced tomatoes (with juice), tomato sauce, and broth to the skillet. Stir to combine. Add in the pre-cooked rice and the cooked ground beef, mixing everything together. Let it simmer for 5 minutes so the flavors meld.

Step 5: Transfer to a Casserole Dish

Lightly grease a 9x13 inch baking dish and transfer the beef and pepper mixture into it. Spread the mixture evenly.

Step 6: Top with Cheese

Generously sprinkle shredded cheddar cheese (or your cheese of choice) over the casserole.

Step 7: Bake the Casserole

Place the casserole in the preheated oven and bake for 20-25 minutes or until the cheese is bubbly and golden brown.

Step 8: Garnish and Serve

Once baked, remove the casserole from the oven and let it sit for about 5 minutes to cool slightly. Garnish with chopped parsley or cilantro, if desired, and serve!

Common Mistakes to Avoid

Cooking any dish for the first time can sometimes come with a few pitfalls. To make sure your Stuffed Pepper Casserole turns out perfect every time, avoid these common mistakes:

• Not pre-cooking the rice: The casserole won't cook the rice properly if it’s added raw. Make sure the rice is fully cooked before adding it to the casserole.
• Skipping the seasoning: The flavors come alive with proper seasoning. Don’t skimp on salt, pepper, and Italian seasoning, or the casserole may taste bland.
• Overcooking the bell peppers: Sauté the peppers until soft but not mushy, as they will continue to cook in the oven.
• Using too much liquid: Too much broth or tomato sauce can make the casserole soupy. Be sure to measure your liquids carefully.
