Cheesy Ground Beef and Potato Casserole

Few dishes deliver the immediate warmth and satisfaction of a bubbling casserole straight from the oven. This ground beef and potato casserole combines tender, thinly sliced potatoes with savory seasoned beef and a rich, velvety mushroom gravy.

Topped with a generous layer of melted Colby Jack cheese, every single bite is creamy, savory, and incredibly comforting.

Casseroles are the backbone of family dinners, offering a complete meal in a single baking dish. This recipe elevates simple, budget-friendly ingredients into something truly spectacular.

By layering thin potato slices with deeply browned ground beef and a smooth mushroom gravy, the potatoes absorb all the savory juices as they bake. The final touch of Colby Jack cheese creates a beautiful, golden crust with an irresistible cheese pull that makes this dish a guaranteed crowd-pleaser.

Ingredients

Why this recipe works

Layering the raw, thinly sliced potatoes directly with the gravy allows them to cook gently in the oven while absorbing maximum flavor. As the casserole bakes, the starch from the potatoes naturally thickens the surrounding mushroom gravy, creating a cohesive, velvety sauce that binds the beef and potatoes together perfectly without becoming watery.

Browning the ground beef first ensures a deep, caramelized flavor base. Cooking the meat with garlic powder, onion powder, salt, and pepper before assembly locks in the seasonings.

This step also allows any excess grease to be drained away, preventing the final casserole from becoming greasy while maintaining a rich, savory profile throughout the layers.

Notes and substitutions

Choosing the right potato is key to achieving the perfect texture. Russet potatoes are excellent because their high starch content helps thicken the gravy, but Yukon Gold potatoes are also a wonderful choice for their naturally buttery flavor and creamy texture. Ensure the slices are uniform in thickness, about one-eighth of an inch, so they cook evenly.

For the cheese topping, Colby Jack offers the perfect combination of mild flavor and superior melting capability.

Freshly grating the cheese from a block is highly recommended, as pre-shredded varieties often contain anti-caking agents that prevent a smooth, stretchy melt. If Colby Jack is unavailable, a mix of cheddar and Monterey Jack works beautifully.

• Colby Jack cheese: Monterey Jack, sharp cheddar, or a pre-packaged Mexican cheese blend.
• creamy mushroom gravy: Cream of onion soup or cream of celery soup mixed with a splash of beef broth.
