Step-by-Step Cooking Instructions

Step 1: Prepare Your Ingredients
Start by gathering and preparing all your ingredients. Dice the bell peppers and onion, mince the garlic, and measure out the rice, broth, and seasonings. Preheat your oven to 375°F (190°C).
Step 2: Cook the Ground Meat
In a large skillet, heat the olive oil over medium heat. Add the ground beef (or turkey) and cook until browned, breaking it up with a spoon as it cooks. Drain any excess fat from the skillet.
Step 3: Sauté the Vegetables
Add the diced onion and bell peppers to the skillet with the cooked meat. Sauté for about 5 minutes, until the vegetables are softened. Add the minced garlic and cook for another minute until fragrant.
Step 4: Combine Ingredients
In the same skillet, add the uncooked rice, diced tomatoes (with their juice), tomato sauce, chicken or vegetable broth, dried oregano, dried basil, salt, and pepper. Stir everything together until well combined.
Step 5: Transfer to a Casserole Dish
Pour the mixture into a greased 9x13-inch casserole dish. Spread it out evenly. Cover the dish tightly with aluminum foil to retain moisture while baking.
Step 6: Bake the Casserole
Bake the casserole in the preheated oven for 45-50 minutes, or until the rice is cooked and tender. Remove the foil and sprinkle the shredded cheese over the top. Return to the oven for an additional 10 minutes, or until the cheese is melted and bubbly.
Step 7: Garnish and Serve
Remove the casserole from the oven and let it sit for a few minutes before serving. Garnish with chopped fresh parsley if desired. Serve hot and enjoy!
How to Cook Stuffed Pepper Casserole: A Step-by-Step Guide
Making stuffed pepper casserole is straightforward if you follow these detailed steps:
- Brown the Meat: Ensure the ground meat is fully browned and crumbled before adding the vegetables.
- Sauté the Vegetables: Cook the vegetables until they are tender but not mushy to retain some texture.
- Combine Ingredients Thoroughly: Mix all ingredients well to ensure even distribution of flavors and rice.
- Cover While Baking: Covering the casserole dish helps retain moisture and cooks the rice evenly.

Common Mistakes to Avoid
Avoid these common mistakes to ensure your stuffed pepper casserole turns out perfectly every time:
- Undercooking the Rice: Make sure the rice is fully cooked before serving. If it’s still crunchy, cover and bake for a bit longer.

- Not Draining Excess Fat: Drain any excess fat from the cooked meat to prevent a greasy casserole.
- Using Too Much Liquid: Stick to the recommended amount of broth to prevent a soupy consistency.
