Ingredients for Stuffed Pepper Casserole

To make the perfect Stuffed Pepper Casserole, you’ll need simple pantry staples and fresh vegetables. Here’s everything broken down for ease:

Main Ingredients:

1 lb ground beef or turkey – Lean meat adds protein and heartiness.
3 bell peppers – Use a mix of red, green, and yellow for color and flavor.
1 small onion – Adds aromatic depth.
3 cloves garlic – Minced for that signature savoriness.
1 cup uncooked white rice – Absorbs all the delicious juices.
2 cups beef broth or chicken broth – Adds richness to the rice as it cooks.
1 (14.5 oz) can diced tomatoes – Juicy bits that blend into the casserole.
1 (8 oz) can tomato sauce – Gives it a saucy, cohesive texture.

Seasonings:

1 tsp Italian seasoning – A perfect herbal mix of basil, oregano, and thyme.
1/2 tsp paprika – For subtle smokiness.
Salt and pepper to taste – Essential for balance.

Finishing Touch:

1 ½ cups shredded cheddar or mozzarella cheese – Melty, gooey topping that makes it irresistible.
Fresh parsley – Optional, but adds a lovely pop of color and freshness.

How to Make Stuffed Pepper Casserole – Step-by-Step Instructions

Ready to whip up this easy, delicious dinner? Follow these simple instructions:

Step 1: Brown the Meat

In a large skillet or oven-safe pot, heat over medium and cook the ground beef (or turkey) until fully browned. Drain any excess fat to keep the casserole from becoming greasy.

Step 2: Sauté the Veggies

Add the diced bell peppers, onion, and minced garlic to the skillet. Sauté for about 3 to 4 minutes, just until they start to soften. The goal is to bring out their flavors without overcooking—remember, they’ll continue cooking with the rice later.

Step 3: Add the Rice and Liquids

Stir in the uncooked rice, diced tomatoes, tomato sauce, and broth. Mix in your Italian seasoning, paprika, and salt & pepper to taste.

Step 4: Simmer Until Tender

Bring the mixture to a gentle boil, then lower the heat. Cover and let it simmer for 18–20 minutes, or until the rice is tender and most of the liquid is absorbed. Stir occasionally to prevent sticking.

Step 5: Bake with Cheese

Preheat your oven to 375°F (190°C). If your skillet isn’t oven-safe, transfer the mixture to a greased 9×13 baking dish. Top with the shredded cheddar or mozzarella cheese, and bake uncovered for 10–15 minutes, or until the cheese is melted and bubbly.

Step 6: Garnish and Serve

Sprinkle with fresh parsley if desired and serve hot. That’s it—your cheesy, comforting Stuffed Pepper Casserole is ready to devour!

Tips for the Best Stuffed Pepper Casserole

Here are some pro tips to take your Stuffed Pepper Casserole to the next level:

Use long-grain rice: It holds its shape well and doesn’t turn mushy.
Cheese choice matters: Mozzarella for gooeyness, cheddar for sharpness, or a blend of both!
Make it spicy: Add a pinch of crushed red pepper flakes or a diced jalapeño.
Let it rest: Give the casserole 5 minutes to rest after baking—it helps the flavors settle and makes scooping easier.

Variations to Try

Don’t be afraid to get creative with your Stuffed Pepper Casserole. Here are some tasty twists:

1. Vegetarian Stuffed Pepper Casserole

Swap the meat for black beans, lentils, or chopped mushrooms. Use vegetable broth instead of beef or chicken.

2. Tex-Mex Style

Add corn, black beans, cumin, and a touch of chili powder. Use Mexican cheese blend for a southwest flair.

3. Italian-Inspired

Use Italian sausage instead of beef, add spinach or zucchini, and finish with parmesan.

4. Low-Carb Option

Replace rice with cooked cauliflower rice. Keep an eye on moisture, as cauliflower releases more water.

5. Quinoa Swap

For added protein and fiber, use quinoa in place of rice. Simmer just as you would with rice but adjust liquid if needed.

What to Serve with Stuffed Pepper Casserole

While Stuffed Pepper Casserole is a meal in itself, you can definitely round it out with these simple sides:

Green Salad – Light and fresh to balance the richness.
Roasted Veggies – Think carrots, zucchini, or Brussels sprouts.
Mashed Potatoes – For the ultimate comfort combo.
Steamed Broccoli – A healthy, colorful addition.

FAQs About Stuffed Pepper Casserole

1. Can I use brown rice instead of white rice?

Yes, but brown rice takes longer to cook and may need more broth. Simmer longer or partially cook it before adding.

2. What meat works best for Stuffed Pepper Casserole?

Ground beef is classic, but ground turkey, chicken, or sausage all work well. Even a mix adds depth of flavor.

3. Can I make this dish dairy-free?

Definitely. Use dairy-free shredded cheese or skip it altogether. The casserole will still be flavorful.

4. How do I prevent the rice from turning mushy?

Use long-grain rice and avoid overcooking. Make sure to simmer gently and stir occasionally to avoid sticking.

5. Can I double the recipe for a crowd?

Yes! Just use a larger pot or baking dish and double all ingredients. Increase simmer and bake time slightly as needed.

6. Is Stuffed Pepper Casserole good for meal prep?

Absolutely. It reheats well and can be portioned into containers for easy lunches or dinners throughout the week.

7. Can I make it in a slow cooker?

Yes, brown the meat first, then transfer everything (except cheese) to a slow cooker. Cook on LOW for 3–4 hours, then top with cheese before serving.
