4-Ingredient Slow Cooker Creamy Potato Bake

Servings: 8 to 10
This effortless slow cooker potato bake combines frozen hash browns, heavy cream, garlic powder, and cheddar cheese for a creamy, comforting side dish.
Ingredients
-
2 pounds frozen diced hash brown potatoes (about 1 large bag, unthawed)
-
2 cups heavy cream
-
2 teaspoons kosher salt
-
1½ teaspoons garlic powder
-
2 cups shredded sharp cheddar cheese, divided
Instructions
Step 1: Prepare the Slow Cooker
Lightly grease a large oval slow cooker (5- to 7-quart) with nonstick spray or a thin film of butter to help prevent sticking and promote golden edges.
Step 2: Make the Cream Mixture
In a large mixing bowl, whisk together the heavy cream, kosher salt, and garlic powder until the seasoning is evenly distributed throughout the cream.
Step 3: Combine Ingredients
Add the frozen diced hash brown potatoes (no need to thaw) and 1½ cups of the shredded cheddar cheese to the bowl. Toss gently with a spatula until all the potatoes are well coated in the creamy mixture and the cheese is evenly dispersed.
Step 4: Transfer to Slow Cooker
Transfer the potato mixture to the prepared slow cooker, spreading it into an even layer and smoothing the top lightly with the back of a spoon.
Step 5: Add Remaining Cheese
Sprinkle the remaining ½ cup shredded cheddar cheese evenly over the surface. This will create that golden, bubbling top you are after.
Step 6: Cook
Cover the slow cooker with the lid and cook on LOW for 4 to 5 hours, or until the potatoes are very tender when pierced with a fork and the edges are bubbling and lightly browned. Avoid lifting the lid during the first 3 hours so the casserole can set and stay creamy.
Step 7: Optional Browning
If you would like a deeper golden top and your slow cooker has a “bake” or “brown” function, use it for the last 15 to 20 minutes. Otherwise, simply let it continue on LOW until the cheese is melted and the edges are lightly caramelized.
Step 8: Rest and Serve
Once done, switch the slow cooker to WARM. Let the casserole rest, covered, for 10 to 15 minutes to thicken slightly before serving. Serve straight from the slow cooker, scooping down through the creamy center to show off the bubbling cheese and tender potatoes.
Tips for the Perfect Slow Cooker Potato Bake
-
Use Frozen Hash Browns: No need to thaw—they cook perfectly in the slow cooker and hold their shape.
-
Do Not Lift the Lid: Keeping the lid on during the first 3 hours of cooking ensures the potatoes cook evenly and the casserole stays creamy.
-
Shred Your Own Cheese: Pre-shredded cheese often contains anti-caking agents that can affect melting. Shredding from a block gives you a smoother, creamier result.
-
Rest Before Serving: Letting the casserole rest for 10 to 15 minutes after cooking allows the sauce to thicken slightly and makes serving easier.
-
Add Extra Flavor: Stir in cooked bacon, sautéed onions, or fresh herbs for variety.
Variations and Substitutions
-
Add Bacon: Stir in ½ cup of cooked, crumbled bacon before cooking.
-
Add Onion: Sauté ½ cup of diced onion and stir into the mixture.
-
Herbed Version: Add 1 teaspoon of dried thyme or rosemary.
-
Spicy Version: Add a pinch of cayenne pepper or red pepper flakes.
-
Different Cheese: Try Gruyère, Monterey Jack, or a blend of your favorites.
-
Lighter Version: Substitute half of the heavy cream with half-and-half or whole milk.

Why This Recipe Works
This recipe succeeds because of its simplicity and the magic of slow cooking. The frozen hash brown potatoes cook gently in the heavy cream, absorbing the rich, savory flavors. The garlic powder adds a subtle depth, while the sharp cheddar cheese melts into a creamy, golden topping.
Cooking low and slow allows the potatoes to become tender without turning mushy, and the cream thickens naturally, creating a velvety sauce that coats every bite.
