Ingredients That Make This Casserole Shine

Ground Beef for Richness

You can substitute ground turkey or chicken if preferred.

Bell Peppers for Sweetness and Color

Chopped bell peppers add natural sweetness, color, and that signature stuffed pepper flavor. Using a mix of red, green, and yellow peppers makes the dish even more vibrant.

Rice That Soaks Up Flavor

Rice absorbs the juices and seasonings, making every bite flavorful. Cooked rice works best, ensuring the casserole bakes evenly and stays tender.

Tomato and Seasonings

Tomato sauce and garlic provide richness and balance, while simple seasonings bring everything together. This classic combination keeps the dish familiar and comforting.

How to Make Stuffed Pepper Casserole Step by Step

Browning the Beef

Start by cooking ground beef in a large skillet until fully browned. Drain excess grease, then add garlic and cook briefly to release flavor.

This step builds the savory base of the casserole.

Adding Peppers and Sauce

Stir chopped bell peppers and tomato sauce into the beef. Simmer briefly so the peppers begin to soften and flavors blend together.

This ensures even texture throughout the dish.

Mixing in the Rice

Add cooked rice and stir well until everything is evenly combined. Taste and adjust seasoning if needed.

At this stage, the mixture already smells incredible.

Baking Until Perfect

Transfer everything to a baking dish, cover, and bake until hot and bubbly. Uncover briefly at the end if adding cheese.

Let the casserole rest slightly before serving.

Easy Customizations to Try

Add Cheese on Top

A layer of shredded cheese melted on top adds richness and makes the dish extra comforting. Cheddar or mozzarella work especially well.

This turns Stuffed Pepper Casserole into a crowd-pleaser for cheese lovers.

Spice It Up
