Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

1 pound ground beef
1/2 cup BBQ sauce, plus extra for topping
1/2 cup breadcrumbs
1 large egg
1/2 onion, finely chopped
1 teaspoon garlic powder
Salt, to taste
Black pepper, to taste
2 cups prepared mashed potatoes
1 1/2 cups shredded cheddar cheese
Chopped green onions, for garnish

Directions

Preheat your oven to 375°F (190°C). Lightly grease a baking dish so the casserole releases easily after baking.

In a large mixing bowl, combine the ground beef, 1/2 cup BBQ sauce, breadcrumbs, egg, chopped onion, garlic powder, salt, and black pepper. Mix until everything is evenly combined, but do not overwork the mixture or the meat layer may become dense.

Press the meat mixture evenly into the prepared baking dish, creating a compact and level base. Bake for 20 minutes, until the meat is mostly cooked through.

Carefully remove the dish from the oven. Spread the prepared mashed potatoes evenly over the meat layer, smoothing the top with a spoon or spatula.

Sprinkle the shredded cheddar cheese evenly over the mashed potatoes. Drizzle a little extra BBQ sauce across the top for added flavor.

Return the dish to the oven and bake for 15 to 20 minutes more, until the cheese is melted, bubbly, and lightly golden around the edges.

Remove from the oven and let it rest for a few minutes before serving. Finish with chopped green onions for a fresh pop of color and flavor.

Servings and timing

This recipe makes 4 to 6 servings, depending on portion size and what you serve alongside it.

Prep time: 15 minutes
Cook time: 40 minutes
Total time: 55 minutes

Variations

You can easily adjust this casserole to match your taste or what you already have in the kitchen.

For a sharper flavor, swap the cheddar for a mix of cheddar and mozzarella or use Monterey Jack for a creamier melt.

To make the mashed potato topping more flavorful, stir a little extra BBQ sauce, roasted garlic, or shredded cheese into the potatoes before spreading them over the meat.

You can also add vegetables for a more complete casserole. Finely chopped bell peppers, corn, or sautéed mushrooms work especially well mixed into the meat layer or served alongside.

For a slightly lighter version, use lean ground beef and reduced-fat cheese while keeping the same cooking method.

Storage/Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. You can also cover the baking dish tightly and refrigerate it directly if that is more convenient.

To reheat, place a portion in the microwave and heat in short intervals until warmed through. For best texture, reheat larger portions in the oven at 350°F (175°C) until hot. Cover loosely with foil if needed to keep the top from over-browning.

This casserole can also be frozen. Let it cool completely, then wrap tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.

FAQs

Can I make this casserole ahead of time?

Yes. You can assemble the casserole earlier in the day, cover it, and refrigerate it until you are ready to bake. If it is going into the oven straight from the refrigerator, it may need a few extra minutes of baking time.

Can I use leftover mashed potatoes?

Yes. Leftover mashed potatoes work very well in this recipe. Just make sure they are easy to spread so they form an even layer over the meat.

What type of BBQ sauce works best?

Any BBQ sauce you enjoy will work. A smoky sauce gives it a deeper flavor, while a sweeter sauce makes the casserole more family-friendly.

How do I know when the meat layer is fully cooked?

The meat should be cooked through with no pink remaining, and the casserole should be hot all the way through. If you use a thermometer, the center should reach a safe internal temperature for ground beef.

Can I use a different cheese?

Yes. Mozzarella, Monterey Jack, Colby Jack, or a blend of cheeses can all be used instead of cheddar.

What should I serve with this casserole?

A green salad, steamed vegetables, roasted carrots, or corn make excellent side dishes. Because the casserole is hearty, simple sides work best.

Can I use instant mashed potatoes?

Yes. Prepared instant mashed potatoes can be used if you need a quicker option. Just prepare them according to package directions before layering.

Why is my meatloaf layer falling apart?

This usually happens if the mixture does not have enough binding ingredients or if it is not pressed evenly into the pan. The breadcrumbs and egg help hold everything together, so measure them carefully.

Can I make this recipe in individual portions?

Yes. You can divide the mixture among small oven-safe dishes for individual casseroles. Keep an eye on the baking time, since smaller portions may cook faster.

Can I add more seasoning?

Absolutely. You can add paprika, onion powder, a pinch of chili powder, or dried herbs to the meat mixture for even more flavor.
