🛒 Ingredients & Why They Matter

Let’s break down each ingredient and its role in making this casserole utterly crave-worthy:

1 pound ground beef

The savory base of the dish. Adds richness, protein, and classic comfort.

2 bell peppers, chopped

Use a mix of red, green, or yellow. These add sweetness, crunch, and signature flavor.

1 onion, finely chopped

Provides a sweet, aromatic backbone and enhances the flavor of the beef.

3 cloves garlic, minced

Intensifies the flavor profile with its deep, savory aroma.

1 tablespoon Worcestershire sauce

A secret weapon for umami! Adds a subtle depth that elevates the beef.

1 (15 oz) can low sodium beef broth

Provides moisture and infuses the rice with a rich, meaty flavor.

1 (15 oz) can diced tomatoes

Brings acidity and texture. Helps balance the richness of the dish.

1 cup uncooked long grain white rice

The heart of the casserole — absorbs all the flavors while adding body.

1 tablespoon Italian seasoning

A blend of herbs (like oregano, basil, and thyme) that boosts the overall flavor.

1 teaspoon salt + 1/2 teaspoon black pepper

Simple seasoning that ties all the ingredients together.

3/4 cup shredded mozzarella cheese

Melts into the casserole for that gooey, stretchy texture we all love.

3/4 cup shredded cheddar cheese

Adds a sharper, tangy contrast to the mozzarella’s creaminess.

👨‍🍳 How to Make Stuffed Pepper Casserole (Step-by-Step)

1. Cook the Ground Beef

In a large skillet or deep sauté pan, brown the ground beef over medium heat, breaking it apart with a spatula until mostly cooked (about 5 minutes).

2. Add Aromatics & Veggies

Stir in the onions and bell peppers. Cook for another 5–10 minutes, until the vegetables begin to soften and the onions turn translucent.

3. Incorporate Garlic

Add the minced garlic and sauté for 1–2 minutes, just until fragrant. Don’t burn it — burnt garlic turns bitter.

4. Add the Remaining Ingredients

Pour in the Worcestershire sauce, beef broth, diced tomatoes (with juices), uncooked rice, Italian seasoning, salt, and pepper. Stir to combine.

5. Simmer & Cook

Bring the mixture to a boil, then reduce the heat to low, cover, and simmer for 20 minutes, stirring halfway through. Cook until the rice is tender and has absorbed most of the liquid.

6. Melt in the Cheese

Once the rice is cooked, stir in half of the mozzarella and cheddar cheese until melted and evenly distributed.

7. Top with More Cheese

Sprinkle the remaining cheese over the top. Cover the skillet again to let the cheese melt (2–3 minutes). For a golden finish, place the skillet under the broiler for 2–4 minutes (if oven-safe).

8. Serve Immediately

Remove from heat and serve hot for the ultimate comfort dish.
