Step‑by‑Step Instructions for Stuffed Pepper Casserole

Step 1: Preheat and Heat Oil
Begin by preheating your oven to 375°F (190°C). In a large skillet, heat a tablespoon of olive oil over medium-high heat. Wait until the oil shimmers in the pan, indicating it’s hot enough to begin cooking. This step will lay the foundation for your Hearty Stuffed Pepper Casserole, enhancing both flavor and texture.

Step 2: Brown the Beef
Add 1½ lbs of lean ground beef to the skillet, breaking it up with a wooden spoon. Cook the beef for about 5-7 minutes, stirring occasionally, until it turns a rich brown and no longer pink. Drain any excess grease to keep your casserole from becoming too oily. This hearty meat will be the star of your dish.

Step 3: Sauté the Vegetables
Stir in 1 diced yellow onion, 1 diced red bell pepper, and 1 diced green bell pepper into the skillet with the beef. Add 3 minced cloves of garlic and sauté for 5-7 minutes, or until the onions become translucent and fragrant. This colorful blend adds depth and aroma to your Stuffed Pepper Casserole, making it truly delicious.

Step 4: Season the Mixture
Once the vegetables are softened, mix in 1 teaspoon of Italian or Cajun seasoning, 2 teaspoons of Worcestershire sauce, ½ teaspoon of salt, and ¼ teaspoon of ground black pepper. Stir thoroughly to ensure the seasonings meld well with the meat and vegetables. This step is crucial for infusing your casserole with rich flavors.

Step 5: Add Tomatoes and Rice
Next, pour in a can of 14 oz diced tomatoes, including their juices, along with 1 cup of uncooked long grain white rice. Stir the mixture until everything is well combined, ensuring the rice is evenly distributed. The rice is essential as it absorbs the flavor and moisture during cooking in the Stuffed Pepper Casserole.

Step 6: Incorporate Broth
Slowly add 1½ cups of beef broth into the skillet, stirring occasionally. Increase the heat to bring the mixture to a gentle boil, then reduce the heat and cover. Allow it to simmer for 20 minutes, or until the rice is cooked through and fluffy, soaking up all the delicious juices from the mixture.

Step 7: Bake the Casserole
After the rice has cooked, transfer the mixture to a greased casserole dish. Top your casserole with 1½ cups of shredded cheese—use cheddar, mozzarella, or a combination of both for a rich topping. Bake in the preheated oven for 15-20 minutes until the cheese is melted, bubbly, and golden. This final step adds that mouthwatering finish to your Hearty Stuffed Pepper Casserole.

Step 8: Garnish and Serve
Once baked, carefully remove the dish from the oven and let it cool for a few minutes. Garnish with fresh parsley for a pop of color and flavor. Serve hot, spooning out generous portions of this comforting casserole, perfect for family dinners. Your Hearty Stuffed Pepper Casserole is now ready to be savored!

Expert Tips for Stuffed Pepper Casserole

Use the Right Rice: Long grain white rice ensures the best texture; if using brown rice, be ready for adjustments in liquid and cooking time.
Add Some Spice: For those who enjoy heat, consider tossing in diced jalapeños or swapping in spicier bell peppers for extra flavor in your Stuffed Pepper Casserole.
Prep Ahead: Make the casserole a day in advance to save time. Simply refrigerate it and add a few extra minutes to the baking time if starting from cold.
Don’t Overcrowd the Pan: When browning the beef, ensure the skillet isn’t overcrowded to achieve a nice sear. This prevents steaming and enhances flavor.
Mix Up the Cheese: Use a combination of cheeses for a richer topping; mixing cheddar and mozzarella creates a gooey, delicious layer that melts beautifully.
