- 1 can (10.5 oz) cream of mushroom soup
- ½ cup sour cream
- ½ cup whole milk
- 2 cups shredded cheddar cheese, divided
- 1 cup shredded mozzarella cheese

Optional Toppings:

- Sliced green onions
- Extra sour cream
Step-by-Step Instructions
Preparing the Beef
Start by browning the ground beef in a large skillet over medium-high heat. This step is crucial – while you could add raw beef directly to the crockpot, browning it first develops deeper flavors and ensures a better texture. Add the diced onion and garlic during the last 2-3 minutes of cooking. Season with salt, pepper, and paprika. Drain any excess fat.
Layering Your Crockpot
Spray your crockpot with cooking spray or use a liner for easy cleanup. Begin with a layer of half the sliced potatoes, slightly overlapping them like shingles. Season lightly with salt and pepper.
In a bowl, mix the cream of mushroom soup, sour cream, milk, thyme, and onion powder until smooth. This will be your binding sauce that keeps everything moist and creamy.
Building the Bake
Spread half of the cooked beef mixture over the potatoes, then pour half of the cream sauce over the beef. Sprinkle with 1 cup of the cheddar cheese. Repeat the layers with the remaining potatoes, beef, and sauce. Reserve the remaining cheese for later.
The Slow Cook
Cover and cook on LOW for 6-7 hours or HIGH for 3-4 hours. The potatoes should be fork-tender when done. During the last 30 minutes of cooking, sprinkle the remaining cheddar and all the mozzarella cheese on top. Cover and let it melt into a golden, bubbly layer.
Pro Tips for Success
Choose the Right Potatoes: Russet potatoes work best because they hold their shape while becoming creamy. Yukon golds are a great alternative for an even butterier texture.
Don’t Skip the Browning: Taking the extra 10 minutes to brown your beef makes a significant difference in the final flavor profile.
Uniform Slicing: Try to slice your potatoes evenly (a mandoline slicer helps!) so they cook at the same rate.
Layer Strategically: Ensure each layer is evenly distributed for consistent flavor in every bite.
Check Your Liquid: If the mixture seems too dry after 4 hours, add a splash of beef broth or milk.
Variations to Try
Loaded Bake: Add a layer of cooked bacon between the beef and cheese layers, and top with chives before serving.
Mexican Style: Swap the cream of mushroom for cream of chicken soup, add a can of diced green chiles, use Mexican cheese blend, and season with cumin and chili powder.
Veggie-Packed: Add layers of sliced bell peppers, mushrooms, or frozen corn for extra nutrition and flavor.
Shepherd’s Style: Mix in frozen peas and carrots with the beef, and use beef gravy instead of cream soup for a more traditional shepherd’s pie flavor.
Make-Ahead and Storage
This dish is perfect for meal prep! You can assemble everything in the crockpot insert the night before, cover, and refrigerate. In the morning, just place the insert in the cooker and add 30 minutes to your cooking time.
Leftovers keep beautifully in the refrigerator for up to 4 days. Reheat individual portions in the microwave, adding a splash of milk if needed to restore creaminess. You can also freeze portions for up to 2 months – just thaw overnight in the refrigerator before reheating.
Serving Suggestions
This hearty bake is essentially a complete meal in itself, but it pairs wonderfully with:
- A crisp green salad with ranch or vinaigrette dressing
- Steamed green beans or roasted Brussels sprouts
- Crusty bread or dinner rolls for soaking up the cheesy sauce
- A dollop of sour cream and fresh chives on top
