*(6-quart slow cooker; serves 8)*
32 oz (about 4 cups) frozen shredded hash browns, thawed and patted dry
1 (10.75 oz) can condensed cream of chicken soup (or cream of mushroom for vegetarian)
1½ cups sour cream
2 cups shredded cheddar cheese, divided
½ cup diced onion (optional, but recommended)
Salt & black pepper to taste
Optional: ½ tsp garlic powder, cooked bacon bits, or chopped chives for garnish.
Step-by-Step Instructions
Step 1: Prep Your Slow Cooker
Grease the inside of a 6-quart slow cooker with nonstick spray or a little butter.
Step 2: Combine the Wet Ingredients
In a large bowl, mix together the cream of chicken soup, sour cream, 1½ cups of the shredded cheddar cheese, diced onion, salt, pepper, and garlic powder (if using).
Step 3: Add the Hash Browns
Add the thawed, patted-dry hash browns to the bowl. Stir until everything is evenly coated.
Step 4: Transfer to Slow Cooker
Pour the mixture into the prepared slow cooker. Spread it into an even layer.
Step 5: Top with Remaining Cheese
Sprinkle the remaining ½ cup of cheddar cheese over the top.
Step 6: Cook
Cover and cook on LOW for 4-5 hours or HIGH for 2-3 hours, until the edges are bubbly and the center is set.
Step 7: Garnish and Serve
Sprinkle with chives or bacon bits if desired. Serve directly from the slow cooker (keep on "warm" setting).
My Best Tips for Success
Pat the hash browns dry. Thaw them first, then press out excess moisture with paper towels. Too much water = watery casserole.
Don't overmix. Stir just until combined. Overmixing can make the texture gluey.
Use full-fat sour cream and cheese. Low-fat versions contain more water, which can make the casserole thin.
Let it rest before serving. Turn off the slow cooker and let the casserole sit for 10-15 minutes. This allows it to set and makes serving easier.
Make it your own. Add bacon, ham, or sautéed bell peppers. Use pepper jack cheese for a spicy kick.

Reheating (microwave): Individual portions take 60-90 seconds.

Frequently Asked Questions
Can I use fresh hash browns instead of frozen?
Yes. Use about 2 lbs of fresh shredded potatoes (like Simply Potatoes). You may need to reduce cook time slightly (fresh potatoes cook faster).
Can I make this without cream soup?
Yes. Make a quick homemade version: melt 2 tablespoons butter, whisk in 2 tablespoons flour, cook for 1 minute, then gradually whisk in 1 cup chicken broth and ½ cup milk. Simmer until thickened. Use in place of the canned soup.
Why is my casserole watery?
Your hash browns weren't dry enough, or you used low-fat dairy. Pat the hash browns dry and use full-fat sour cream and cheese.
Can I cook this on high?
Yes. Cook on HIGH for 2-3 hours. The texture will be slightly less creamy, but still delicious.
Can I add eggs to make it a full breakfast casserole?
Yes. Whisk 4-6 eggs and pour over the top before cooking. Cook on LOW for 4-5 hours. The eggs will set into the casserole.
