Stuffed Pepper Casserole Ingredients • Get ready to create a warm family favorite! For the Casserole Lean Ground Beef – Provides savory protein and a rich flavor; can substitute with ground turkey for a lighter option. Cooked Rice (White or Brown) – Acts as a comforting filler that absorbs the flavors; brown rice adds fiber but adjust cooking time accordingly. Bell Peppers (Red, Green, or Yellow) – Adds vibrant color and mild sweetness; mixing varieties creates diverse flavors. Onion – Contributes aromatic sweetness when sautéed, forming a flavorful base. Garlic – Enhances overall flavor and aroma, vital for a fragrant casserole. Diced Tomatoes (15 oz can) – Adds juiciness and acidity, creating a luscious sauce throughout. Tomato Sauce (8 oz can) – Binds ingredients and intensifies tomato flavor; crushed tomatoes for a chunkier texture also work. Italian Seasoning – Delivers classic Mediterranean flavor, blending herbs like oregano and basil. Salt and Black Pepper – Essential seasonings to enhance all flavors uniformly. For the Topping Mozzarella Cheese (2 cups, shredded) – Offers a creamy, melty layer to enhance the casserole’s richness. Cheddar Cheese (1 cup, shredded) – Provides a sharp flavor and a lovely golden-brown finish on top. For Cooking Olive Oil (2 tbsp) – Used for sautéing onion and garlic, contributing healthy fats and flavor. For Garnish (Optional) Fresh Parsley (1/4 cup, chopped) – Adds a burst of brightness and color when garnished before serving. With these ingredients, you’re well on your way to making a delicious Stuffed Pepper Casserole that will satisfy and delight your family! Step‑by‑Step Instructions for Stuffed Pepper Casserole Step 1: Preheat the Oven Start by preheating your oven to 375°F (190°C). This ensures a perfectly baked Stuffed Pepper Casserole. While the oven warms up, gather your ingredients for a smooth cooking experience. Step 2: Sauté Aromatics In a large skillet over medium heat, add 2 tablespoons of olive oil. Once hot, sauté 1 diced onion and 2 minced garlic cloves until they become translucent, about 3-4 minutes. Stir occasionally, allowing the aromatic flavors to develop beautifully. Step 3: Brown the Meat Add 1 pound of lean ground beef to the skillet. Cook for about 5-7 minutes, breaking it apart with a spatula until it’s browned and no pink remains. Drain any excess fat to keep the casserole from being greasy, ensuring a delicious flavor. Step 4: Add Vegetables Stir in 2 cups of diced bell peppers (a mix of colors adds cheer!). Cook for another 3-4 minutes until they soften slightly. The vibrant colors will brighten your skillet and create the perfect base for your Stuffed Pepper Casserole. Step 5: Combine Ingredients Next, stir in 3 cups of cooked rice, 1 can of diced tomatoes (15 oz), and 1 can of tomato sauce (8 oz). Add 1 tablespoon of Italian seasoning, and season well with salt and black pepper. Mix until all ingredients are evenly combined, creating a hearty filling. Step 6: Simmer the Mixture Reduce the heat to low and let the mixture simmer for about 10 minutes. Stir occasionally to allow the flavors to meld beautifully, filling your kitchen with an inviting aroma as everything comes together perfectly. Step 7: Incorporate Cheese Remove the skillet from heat and fold in 1 cup of shredded mozzarella cheese into the mixture until it melts slightly. This addition not only enhances flavors but also contributes to the creamy texture of your Stuffed Pepper Casserole. Step 8: Prepare the Baking Dish Transfer the mixture to a greased 9×13 baking dish, spreading it out evenly with a spatula. This ensures that every bite is filled with all the delicious layers you’ve created, making it easy to serve. Step 9: Add Toppings Sprinkle the remaining 1 cup of mozzarella and 1 cup of cheddar cheese evenly over the top. This cheesy layer is essential for achieving that melty, golden-brown finish you crave in a Stuffed Pepper Casserole. Step 10: Bake with Foil Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 20 minutes to allow the flavors to meld while keeping the casserole moist and tender. Step 11: Uncover and Finish Baking After 20 minutes, carefully remove the foil and return the casserole to the oven. Bake for an additional 10 minutes, or until the cheese is bubbly and slightly browned. This is the moment your kitchen will be filled with irresistible aromas. Step 12: Rest and Serve Once done, remove the casserole from the oven and let it rest for 5 minutes. This helps the layers set, making it easier to serve. If desired, sprinkle with chopped fresh parsley for a pop of color before dishing it out for everyone to enjoy!
