The beauty of this Stuffed Pepper Casserole Recipe lies in its simplicity. Each ingredient plays a starring role in creating layers of flavor, from the juicy bell peppers to the fragrant spices and the creamy cheese that brings it all together. Here’s what you’ll need to make this magic happen:

2 tablespoons olive oil: Adds a rich base for sautéing the meat and vegetables, enhancing their natural flavors.

1 ½ pounds ground beef (lean): Provides the hearty protein foundation that keeps this dish filling and satisfying.
1 yellow onion, diced: Offers a sweet, aromatic note that balances the savory elements in the dish.
1 medium red bell pepper, diced: Gives a pop of color and gentle sweetness that brightens every bite.

1 medium green bell pepper, diced: Adds crunch and a slightly earthy flavor that complements the red pepper perfectly.
3 small cloves garlic, minced: Infuses the casserole with a warm, inviting aroma that you’ll love.
1 teaspoon Italian seasoning or Cajun seasoning: Choose your preferred spice blend for a personalized flavor twist.

2 teaspoons Worcestershire sauce: Deepens the savory notes with its tangy, umami richness.
½ teaspoon salt: Enhances all the flavors without overpowering.
¼ teaspoon ground black pepper: Adds just the right amount of subtle heat.
14 ounces canned diced tomatoes: Brings juiciness and a touch of acidity for balance.

1 cup long grain white rice: Absorbs all the wonderful flavors while giving the casserole a satisfying texture.
1 ½ cups beef broth: Keeps the rice perfectly moist and infuses it with savory goodness.
1 ½ cups shredded cheese (cheddar, mozzarella, or both): Melts beautifully over the casserole for a gooey, irresistible topping.

Parsley for garnish: Adds a fresh, bright finish to the dish.

How to Make Stuffed Pepper Casserole Recipe

Step 1: Prepare the Base

Heat olive oil in a 3.5-quart ovenproof skillet or casserole pan over medium-high heat. Add the ground beef and sauté, breaking it up with a spatula until it’s no longer pink. This step builds the hearty foundation of your casserole, and draining excess fat here keeps the dish light yet flavorful.

Step 2: Sauté the Aromatics

Next, toss in the diced yellow onion and both red and green bell peppers. Let them cook for 2 to 3 minutes until the vegetables soften just slightly, releasing their natural sweetness and inviting aroma. Adding these colorful peppers now ensures they retain a nice bite and vibrancy.

Step 3: Add Garlic and Seasonings

Stir in the minced garlic along with Italian seasoning or Cajun seasoning, Worcestershire sauce, salt, and pepper. Cook everything together for about 30 seconds. This quick step unlocks the fragrant spices and blends all those gorgeous flavors perfectly before adding the liquids.

Step 4: Combine Tomatoes and Rice

Pour in the canned diced tomatoes followed by the uncooked long grain white rice and beef broth. Stir to mix everything evenly and bring the mixture to a gentle boil. The diced tomatoes add juiciness, while the rice begins soaking up that rich broth and seasoning in this one-pan wonder.

Step 5: Bake the Casserole

Cover the skillet with a lid or foil and transfer it to the oven preheated at 350°F (180°C). Bake for 20 to 25 minutes, checking that the rice is tender by tasting. If it feels a bit crunchy, pop it back in and add a splash of water if needed. This slow, even cooking ensures every grain of rice is perfectly fluffy and infused with flavor.

Step 6: Add Cheese and Broil

Remove the casserole from the oven and sprinkle the shredded cheese generously on top. Place the skillet under the broiler for 3 to 5 minutes until the cheese melts and bubbles up with golden brown edges. This step adds that irresistible cheesy crust that makes the dish unforgettable.

Step 7: Garnish and Serve

Finish by sprinkling fresh parsley over the hot casserole. This simple garnish not only makes your dish look stunning but also adds a fresh, herbaceous contrast to the rich, cheesy layers beneath.

How to Serve Stuffed Pepper Casserole Recipe

Garnishes

Besides vibrant parsley, you can add a dollop of sour cream or a sprinkle of crushed red pepper flakes for a little extra creaminess or heat. Freshly cracked black pepper on top right before serving also freshens the flavor beautifully.

Side Dishes

This casserole is a complete meal on its own, but if you want to round it out, consider serving it alongside a crisp green salad or some steamed green beans. A crusty piece of garlic bread also pairs wonderfully for soaking up any leftover juices.

Creative Ways to Present

Serve this dish straight from the skillet to the table for a warm, rustic feel. Alternatively, you can portion it into individual ramekins for a charming presentation at dinner parties or family gatherings. Either way, it’s sure to impress!

Make Ahead and Storage

Storing Leftovers

Once cooled, transfer leftover Stuffed Pepper Casserole to an airtight container and keep it in the refrigerator for up to 3 days. It reheats perfectly, making it a great option for quick lunches or dinners.

Freezing

If you want to save some for later, this casserole freezes beautifully. Place it in a freezer-safe container for up to 3 months. Be sure to thaw overnight in the refrigerator before reheating for the best texture.

Reheating

To reheat, warm the casserole in the oven at 350°F (175°C) until heated through, about 15 to 20 minutes. If you’re in a hurry, microwave individual portions covered with a damp paper towel to keep it moist.

FAQs

Can I use ground turkey or chicken instead of ground beef?

Absolutely! Ground turkey or chicken can be great lean alternatives. Just keep in mind the cooking time might vary slightly, and you may want to add a touch more seasoning for extra flavor.

What’s the best cheese to use for this casserole?

Cheddar and mozzarella are classic choices because they melt smoothly and offer great flavor. Mixing both gives you a perfect balance of sharpness and creaminess, but feel free to try pepper jack for a spicy twist.

Can I make this recipe vegetarian?

Yes, you can swap the ground beef for plant-based meat substitutes or extra beans and mushrooms for a hearty texture. Just adjust seasoning to make sure it stays flavorful!

Is it necessary to broil the cheese on top?

While not absolutely required, broiling creates a gorgeous golden, bubbly crust that elevates the dish. Without it, the cheese will melt nicely but won’t have that slightly crispy topping.

Can I prepare the casserole ahead of time and bake it later?

Definitely! You can assemble everything up to the baking step, cover the casserole, and refrigerate it overnight. When ready, just bake as directed. This makes it incredibly convenient for busy days.
