Ingredients

To create this delicious Stuffed Pepper Casserole, gather the following ingredients, each bringing its unique flavor and texture to the dish:

2 Tbsp. extra-virgin olive oil – This golden oil adds a rich flavor and aroma as it sizzles in the pan.
1 lb. (80%) lean ground beef – Tender, juicy beef that forms the hearty base of the casserole.
2 bell peppers, any color, chopped into 1" pieces – Bright and crunchy, they inject color and sweetness into the dish.
1 large yellow onion, chopped into 1" pieces – Aromatic and caramelizing beautifully, it enhances the overall taste.
3 cloves garlic, thinly sliced – This fragrant herb elevates every bite with its robust flavor.
2 tsp. kosher salt – Essential for bringing out the flavors of the other ingredients.
1 tsp. freshly ground black pepper – Adds a mild warmth and juxtaposes the sweetness of the peppers and onions.
1 tsp. ground cumin – This earthy spice brings a delightful depth to the dish.
1 tsp. smoked paprika – Infests the dish with a hint of smokiness that is utterly comforting.
1/2 tsp. dried oregano – A pinch of this herb evokes Mediterranean vibes and adds complexity.
1 (6-oz.) can tomato paste – Concentrated tomato flavor that binds the casserole together.
1 (14.5-oz.) can fire-roasted diced tomatoes – These tomatoes add sweetness and a touch of smokiness.
1 1/2 cups beef broth – Both liquid and flavor that makes the rice tender and delicious.
1 cup basmati rice – Nutty and fluffy, it absorbs all the savory juices beautifully.
2 cups shredded pepper Jack cheese (about 8 oz.) – Creamy and spicy, the ultimate topping that makes this casserole irresistible.
1 Tbsp. finely chopped fresh cilantro – Adds a hint of brightness and freshness as a garnish.

Step-by-Step Directions

Preheat your oven to 350 degrees Fahrenheit. This is the magic temperature where your casserole will bubble and bake to perfection.

In a large Dutch oven over medium heat, pour in the olive oil. As the oil shimmers and heats up, add the ground beef. Cook for about 4 to 6 minutes until fully browned, breaking it apart as it cooks to ensure even browning.

Incorporate the chopped bell peppers, onion, and sliced garlic into the pot. Season with kosher salt, black pepper, cumin, smoked paprika, and oregano. Stir occasionally for about 1 minute until fragrant, allowing the vegetables to sweat and soften.

Add the tomato paste, stirring it in for an additional 2 minutes while cooking. This crucial step enhances the sauce’s richness.

Pour in the fire-roasted diced tomatoes, beef broth, and basmati rice. Give it a good stir, scraping up any brown bits from the pot’s bottom, which adds depth to your dish.

Increase the heat to high and bring the mixture to a boil. Once boiling, immediately cover the pot and transfer it to the preheated oven. Bake for 20 to 24 minutes, or until the rice is tender.

Once cooked, remove the casserole from the oven and set your broiler to high. Stir the casserole and sprinkle the shredded pepper Jack cheese generously on top. Return it to the oven, uncovered, and broil for about 3 to 4 minutes until the cheese is golden brown and bubbly.

Remove from the oven and top with finely chopped fresh cilantro, adding a burst of color and freshness to your hearty casserole.

Tips & Tricks

For an added flavor boost, consider sautéing the garlic until it’s fragrant before adding the beef, which can enhance the overall depth of flavor. If you prefer a vegetarian option, swap the ground beef for lentils and increase the variety of vegetables. Additionally, feel free to experiment with different kinds of cheese for varied flavor profiles. The casserole can also be easily adapted to include rice substitutes like quinoa or cauliflower rice for a low-carb option.

For a heartier meal, serve it alongside garlic bread or a warm crusty loaf for dipping. It’s an excellent choice for potlucks, casual family gatherings, or as a comforting weeknight dinner when you’re craving something warm and filling.
