Slow Cooker Flag Day Potatoes
Prep Time: 5 minutes
Cook Time: 4–5 hours on LOW or 2–3 hours on HIGH
Servings: 6
Ingredients
- 8 frozen hash brown patties (approximately 24 ounces)
- 1 can (10.5 ounces) condensed cream of chicken soup
- 1 cup sour cream
- 2 cups shredded cheddar cheese, divided
Instructions
1. Prepare the Slow Cooker
Coat the inside of a 4- to 6-quart slow cooker with nonstick cooking spray to help prevent sticking and make cleanup easier.
2. Arrange the Potatoes
Place the frozen hash brown patties in the bottom of the slow cooker. A little overlap is fine, but try to create an even layer.
3. Mix the Sauce
In a mixing bowl, combine the cream of chicken soup and sour cream until smooth. Stir in 1½ cups of the shredded cheddar cheese.
4. Assemble
Spread the creamy cheese mixture evenly over the hash brown patties, making sure most of the potatoes are covered.
5. Slow Cook
Cover and cook on LOW for 4 to 5 hours or HIGH for 2 to 3 hours. The potatoes should become tender and the mixture should be hot and bubbly around the edges.
6. Add the Remaining Cheese
About 15 to 20 minutes before serving, sprinkle the remaining ½ cup cheddar cheese over the top. Replace the lid and allow the cheese to melt completely.
7. Serve
Switch the slow cooker to the WARM setting and serve directly from the crock. Allowing the casserole to rest uncovered for several minutes will help it firm up slightly for easier serving.
Helpful Tips
Use Frozen Potatoes Straight From the Freezer
There’s no need to thaw the hash brown patties beforehand. They soften perfectly during cooking and create the ideal creamy texture.
Choose Full-Fat Sour Cream
For the richest flavor and best consistency, regular sour cream works best. Reduced-fat versions can be used but may produce a thinner sauce.
Freshly Shredded Cheese Melts Better
If possible, shred cheese from a block rather than using pre-packaged shredded cheese. It melts more smoothly and provides a creamier finish.
Alternative Soups
Cream of mushroom or cream of celery soup can easily replace cream of chicken soup if desired.
Easy Variations
Loaded Potato Version
Mix sliced green onions into the casserole and top with crispy bacon and additional sour cream before serving.
Ham and Cheese Potatoes
Add 1½ cups diced cooked ham to turn this side dish into a hearty main course.
Broccoli Cheddar Potatoes
Stir in 2 cups thawed, drained broccoli florets for added color and nutrition.
Spicy Jalapeño Potatoes
Mix chopped pickled jalapeños into the sauce and swap part of the cheddar for pepper jack cheese.
Mushroom Swiss Casserole
Replace the cheddar with Swiss cheese and use cream of mushroom soup for a richer flavor profile.
Buffalo Chicken Style
Add shredded cooked chicken and buffalo sauce to create a spicy, game-day-inspired casserole.
