Preparing Stuffed Pepper Casserole
Creating a delightful stuffed pepper casserole is not only a treat for the taste buds, but it also fills the kitchen with a comforting aroma. Let’s walk through the steps to make this dish, ensuring simplicity and flavor shine throughout the cooking process.
Gather Your Ingredients
Before we dive into cooking, it's crucial to assemble all your ingredients. Here’s what you'll need:
- 2 Tbsp. olive oil, plus more for greasing the baking dish
- 1 medium yellow onion, chopped
- 1 red bell pepper, cut into 1-inch pieces
- 1 green bell pepper, cut into 1-inch pieces
- 1 lb. ground beef (80/20)
- 2 Tbsp. tomato paste
- 1 ½ tsp. kosher salt
- 1 tsp. ground cumin
- 1 tsp. paprika
- ½ tsp. black pepper
- 4 garlic cloves, finely chopped
- 4 vine-ripened tomatoes, chopped
- 1 large zucchini, quartered lengthwise and sliced
- 2 cups chicken broth
- 1 cup long-grain white rice
- ¼ cup fresh parsley or cilantro, chopped, plus more for sprinkling
- 1 Tbsp. Worcestershire sauce
- 2 cups shredded pepper jack cheese (about 8 ounces)
This list covers everything essential for a delicious casserole. Make sure to have all these items ready before proceeding.
Sauté the Vegetables
Start your casserole by heating the olive oil in a large skillet over medium heat. Add the onions and both bell peppers, cooking them until softened, roughly 3 to 5 minutes. This step creates a lovely base flavor. The vibrant colors of the peppers not only look great but also enhance the dish’s appeal.
Cook the Ground Beef
Next, add the ground beef into the skillet once the vegetables have softened. Break up the meat gently with a wooden spoon, ensuring it cooks evenly. This usually takes about 6 to 8 minutes. As the beef browns, add in tomato paste, salt, ground cumin, paprika, and black pepper. Stir frequently, allowing the mixture to become fragrant—this is where the magic starts to happen!
Combine Flavors with Rice and Broth
Incorporate the chopped tomatoes and zucchini and cook for another 3 to 5 minutes. Now, it’s time to introduce the chicken broth, rice, Worcestershire sauce, and half of your cheese into the mix. Stir everything together to ensure a perfect blend of flavors. The rice will start to soak up those rich ingredients, amplifying the taste of your stuffed pepper casserole.
Bake to Perfection
Preheat your oven to 350°F and grease your baking dish with a bit more olive oil. Transfer the hearty mixture into the baking dish and cover it with aluminum foil. Bake for about 50 minutes to an hour until the rice is tender and the liquid is absorbed. Once done, remove the foil, stir the casserole, and sprinkle the remaining cheese on top. Broil for 2 to 3 minutes until the cheese is melted and bubbly. Let it cool for a few minutes, and don’t forget to add extra chopped parsley before serving!
By following these straightforward steps, you’re on your way to creating a comforting and delectable stuffed pepper casserole that will impress both friends and family alike. Happy cooking!

Variations on Stuffed Pepper Casserole
Vegetarian Stuffed Pepper Casserole
Switching to a vegetarian stuffed pepper casserole is a fantastic way to enjoy this dish without meat. Replace the ground beef with a mix of black beans, chickpeas, and chopped mushrooms for added flavor. You can also introduce a variety of veggies like corn, spinach, or even quinoa for a nutritious boost. Top it with your favorite cheese or a dairy-free alternative to keep it creamy. This way, you’ll achieve that satisfying heartiness while ensuring it’s plant-based!
Spicy Stuffed Pepper Casserole
If you crave a kick, try a spicy stuffed pepper casserole. Incorporate jalapeños or chipotle peppers for heat, or toss in some crushed red pepper flakes. You can also consider using spicy sausage as a flavorful substitute for ground beef. Add a dash of hot sauce directly into the casserole for a fiery finish. This version pairs well with refreshing toppings like avocado or a cool sour cream dollop to balance the spice.

Cooking Tips and Notes for Stuffed Pepper Casserole
Tips for Achieving the Perfect Texture
To master the texture of your stuffed pepper casserole, consider the rice you use. Long-grain white rice works beautifully, but if you prefer a firmer texture, opt for jasmine or basmati rice. Ensure that you allow the casserole to rest for about five minutes after it comes out of the oven—this lets the flavors meld and the texture set. When broiling for that golden cheese top, keep an eye on it, as it can go from bubbly to burnt in the blink of an eye!
Notes on Ingredient Substitutions
Versatility is key with this stuffed pepper casserole. If you're looking for healthier options, swap ground beef for turkey or use a plant-based meat alternative. Fresh herbs like parsley or cilantro can be exchanged with basil or thyme, depending on your taste. Don’t have zucchini? Feel free to toss in other vegetables, like corn or mushrooms, for added nutrition and flavor! For more suggestions on ingredient swaps, check out this resource on ingredient substitutions.
