Ingredient Notes & Details

Ground Beef
Use lean ground beef (80/20 or 85/15) for the best flavor without too much grease. You can also substitute ground turkey or chicken for a lighter version.

Bell Peppers
A mix of red, green, and yellow bell peppers adds both sweetness and color. Fresh peppers work best for this oven roasted bell pepper casserole.

Onion
Adds depth and sweetness as it cooks. Yellow or white onions are ideal.

Garlic
Fresh minced garlic gives the best flavor, but garlic powder can work in a pinch.

Cooked Rice
White rice is classic, but brown rice or even cauliflower rice can be used for a low carb Stuffed Bell Pepper Casserole.

Tomato Sauce
Use a good-quality canned tomato sauce for rich flavor. You can also mix in diced tomatoes for extra texture.

Diced Tomatoes (Optional)
Adds a bit more body and freshness to the casserole.

Italian Seasoning
A simple blend that ties all the flavors together beautifully.

Salt & Black Pepper
Adjust to taste—don’t skip this step for proper seasoning.

Shredded Cheese
Cheddar or mozzarella works perfectly. It creates that irresistible cheesy bell pepper side dish feel on top.

Step-by-Step Instructions

Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C). Lightly grease a large baking dish to prevent sticking.

Step 2: Cook the Ground Beef
In a large skillet over medium heat, cook the ground beef until browned. Break it apart as it cooks. Once fully cooked, drain any excess grease.

You’ll know it’s ready when the meat is no longer pink and has a slightly crispy texture around the edges.

Step 3: Sauté the Vegetables
Add the chopped onions and bell peppers directly into the skillet with the beef. Cook for about 5–7 minutes, stirring occasionally, until the vegetables soften and become fragrant.

The peppers should be tender but still slightly firm—this helps them hold their texture after baking.

Step 4: Add Garlic and Seasoning
Stir in the minced garlic and cook for about 30 seconds until fragrant. Then add Italian seasoning, salt, and pepper.

This step builds that rich, savory base that makes this dish so comforting.

Step 5: Combine the Sauce and Rice
Pour in the tomato sauce and diced tomatoes (if using). Stir everything together until well combined.

Add the cooked rice and mix thoroughly, making sure the rice is evenly coated in the sauce.

The mixture should look thick, hearty, and well blended.

Step 6: Transfer to Baking Dish
Pour the mixture into your prepared baking dish and spread it evenly.

At this point, it already smells amazing—but the oven is where the magic really happens.

Step 7: Add the Cheese
Sprinkle a generous layer of shredded cheese over the top.

Don’t hold back here—this is what gives you that golden, bubbly finish.

Step 8: Bake to Perfection
Bake uncovered for 20–25 minutes, or until the cheese is melted and lightly golden.

You’ll know it’s ready when the edges are bubbling and the top looks irresistibly cheesy.

Step 9: Rest and Serve
Let the casserole sit for about 5 minutes before serving. This helps everything set and makes it easier to scoop.

Serve warm and enjoy every comforting bite.
