This ground beef potato casserole is the ultimate weeknight comfort meal with golden Yukon potatoes, hearty seasoned beef, and melty Colby jack cheese all layered in a rich and savory mushroom cream sauce.

Step-by-Step Instructions
- Prepare the Potatoes:
- Slice Yukon gold potatoes into very thin one eighth inch slices and submerge them in cold water to avoid browning while you prepare the rest of the dish
- Preheat and Prepare the Dish:
- Set your oven to three hundred fifty degrees Fahrenheit Spray a nine by thirteen inch baking dish with cooking spray and set it aside
- Brown the Beef and Aromatics:
- Set a large saucepan over medium high heat Add lean ground beef along with the finely diced onions and minced garlic Cook while breaking up the beef with a spoon until it is browned and the onions are soft Drain any excess oil to keep the casserole from becoming greasy
- Mix the Cream Sauce:
- In a medium mixing bowl stir together cream of mushroom soup with half and half onion powder kosher salt and freshly ground black pepper until the mixture is completely smooth This will make your sauce extra silky
- Assemble the Casserole Layers:
- Drain the prepared potato slices Layer one third of the potatoes in the bottom of your baking dish Next spread one third of the cooked beef mixture followed by three quarters cup of shredded Colby jack cheese and one third of the mushroom soup mixture Repeat these layers for the next third of the ingredients
- Top and Finish the Layers:
- For the last layer add the remaining potatoes and ground beef Pour the last of the soup mixture over everything then scatter the remaining one and one half cups of Colby jack cheese on top
- Bake the Casserole:
- Cover tightly with aluminum foil Set in your preheated oven and bake for one hour and ten minutes Remove the foil and bake for another twenty minutes so the cheese browns nicely Let the casserole sit out for fifteen minutes so the juices settle before serving

My kids always hover near the kitchen when this bakes and their favorite part is the golden crust of cheese on top I will always remember them fighting over the corners when they were little
Storage Tips
Store leftovers in a tightly covered dish in the refrigerator for up to four days warm slices in the microwave or a low oven for best texture You can freeze cooled portions in single serving containers for easy future meals Just thaw in the fridge overnight and reheat thoroughly
Ingredient Substitutions
Swap russet potatoes if you do not have Yukon golds the texture will be slightly drier but still works Chicken or turkey can stand in for the ground beef if you prefer a lighter flavor If you need a gluten free version use a gluten free cream soup and double check your cheese and other ingredients for gluten Monterey jack or cheddar cheese can be used in place of Colby jack for a similar gooey result
Serving Suggestions
Pair this hearty casserole with a crisp green salad or steamed green beans for a classic meal The cheesy beefy layers also taste great with a spoonful of tangy sour cream or a sprinkle of fresh green onions on top For true comfort food vibes serve alongside some warm bread or rolls to mop up the creamy sauce
