Crockpot Cheesy Hashbrown Casserole Recipe for Slow Cooker

This crockpot hashbrown casserole is a comforting, easy-to-make dish that brings cheesy, creamy goodness to any meal.

Perfect for holiday dinners, brunches, or weeknight sides, this slow cooker casserole frees up oven space and lets you focus on other tasks while it cooks low and slow until bubbly and golden.

The combination of tender shredded potatoes, creamy sour cream, and sharp cheddar melts together into a luscious casserole with a top layer of melted cheese that makes everyone come back for seconds. It pairs wonderfully with roast chicken, turkey, ham, or a hearty breakfast spread.

Making this casserole in a crockpot is convenient and hands-off: you simply mix the ingredients, add them to a well-sprayed insert or liner, set the cooker, and let it do the work. When it’s ready, finish with extra cheese on top for a melty, irresistible finish.

• Simple, wholesome ingredients deliver a crowd-pleasing side or breakfast casserole.
• Flexible — easy to adapt with proteins or extra vegetables.

Ingredients

See the recipe card below for exact amounts and a printable version.

• Frozen shredded hash brown potatoes — add them straight from frozen for convenience.
• Sour cream — adds tang and creaminess.
• Sharp cheddar cheese — shredded; reserve some for topping.
• Onion powder — or 1/4 cup finely chopped onion, if you prefer fresh.
• Garlic powder
• Salt and black pepper
• Non-stick cooking spray or a slow cooker liner to make cleanup easy.
• Optional garnishes — sliced green onions or chopped parsley.

Instructions

Prepare the crockpot for non-stick success by spraying the insert liberally with non-stick spray or lining it with a slow cooker liner.

• Step 1: In a large bowl, combine the entire package of frozen shredded hash browns with sour cream, shredded cheddar (reserve about 1 cup for the top), onion powder, garlic powder, and a generous pinch of salt and black pepper. Mix until evenly combined.
• Step 2: Transfer the mixture to the prepared crockpot and smooth the top.
• Step 3: Cook on high for 3–4 hours or on low for about 6 hours, until the casserole is heated through and set.
• Step 4: Set the crockpot to low (or turn off) and sprinkle the reserved cheese over the top. Cover until the cheese melts, then remove the lid and let the casserole rest a few minutes before serving.

Serving the casserole

Let the casserole rest a few minutes after cooking, then scoop portions onto plates and garnish with sliced green onions or chopped parsley. Serve warm.

• Great alongside roasted meats or as part of a brunch buffet.
• Holds well in the slow cooker on warm for a short period, but avoid keeping it on high heat for extended times to preserve texture.

Variations

• Ground beef: Brown and drain the beef, then layer or stir it into the potato mixture for a heartier casserole.
• Sausage: Cooked, crumbled sausage adds savory richness.
• Cheese swap: Use Monterey Jack with cheddar for a milder, slightly spicier blend.
• Vegetables: Fold in 1/2 cup finely chopped red or green bell pepper for color and crunch.

Storage and reheating

Store leftovers properly to preserve flavor and texture:

• Cool: Allow the casserole to reach room temperature before storing.
• Refrigerate: Transfer to an airtight container and keep in the refrigerator for up to 3–4 days.
• Reheat in the oven: For best texture, reheat at 350°F covered with foil until warmed through (about 15–25 minutes).
• Reheat in the crockpot: Spray the insert, add leftovers, and warm on low until hot, stirring gently to ensure even heating.

Reheating instructions

• Oven: Preheat to 350°F, cover the dish with foil to retain moisture, and bake until heated through (about 20 minutes).
• Slow cooker: Heat on low until hot, checking occasionally and stirring if needed.

Tips

• Know your slow cooker: some run hot. I used a 6-quart oval unit that trends warm, so adjust cook times as needed.
• For a tangier, slightly lighter texture, reduce the sour cream and substitute some cream cheese if desired.
• For added crunch, sprinkle crushed cornflakes mixed with melted butter over the top before serving.
