This slow cooker hash brown casserole is the kind of practical, crowd-pleasing dish that earns a permanent place at late-summer cookouts, especially when you want something hearty that can hold on a buffet table. Using frozen O'Brien-style hash browns keeps the prep short while the slow cooker turns them creamy and tender, and a quick finish creates those coveted crispy, cheesy edges everyone reaches for first.
Serve this casserole alongside burgers, grilled bratwurst, barbecue chicken, pulled pork, or smoked ribs for a satisfying pre-Labor Day spread. It also works well with a crisp green salad, sliced tomatoes, pickles, baked beans, or fresh fruit, and a scoop on the side of scrambled eggs makes the leftovers especially good the next morning.
5-Ingredient Slow Cooker Pre-Labor Day Cookout Crispy Edge Cheesy Hash Brown Casserole
Servings: 10 to 12
Ingredients
2 bags (about 30 ounces each) frozen O'Brien style hash browns, thawed
2 cans (10.5 ounces each) condensed cream of chicken soup
2 cups sour cream
4 cups shredded sharp cheddar cheese, divided
6 tablespoons melted butter
Directions
1. Lightly butter or spray a 6- to 8-quart slow cooker crock. In a large mixing bowl, combine the thawed hash browns, condensed soup, sour cream, 3 cups of the cheddar, and the melted butter. Stir until the potatoes are evenly coated.
2. Spoon the mixture into the slow cooker and spread it into an even layer. Cover and cook on low for 4 to 5 hours or on high for 2 1/2 to 3 hours, until the potatoes are tender and the casserole is hot throughout.
3. Uncover, sprinkle the remaining 1 cup cheddar over the top, and continue cooking for 15 to 20 minutes, just until the cheese melts.
4. For crispier edges, transfer the crock insert if broiler-safe, or spoon the casserole into a buttered broiler-safe baking dish. Broil for 3 to 5 minutes, watching closely, until the top and edges are deeply golden and crisp in spots. Let stand 10 minutes before serving.
Variations & Tips
Make it extra cheesy: If your crowd loves a richer casserole, increase the cheddar to 5 cups and fold an extra cup into the potato mixture before slow cooking. This gives the center a softer, more spoonable texture.
For the crispiest finish: Slow cookers are excellent for keeping casseroles moist, but they do not naturally brown much on top. That quick broiler step at the end is the best way to get the browned, crunchy edges people fight over.
Swap the soup: Cream of mushroom or cream of celery works nicely if you want a slightly different flavor profile or need to use what is already in the pantry. The method stays the same.
Hold for a cookout: Once fully cooked, keep the casserole on the warm setting for up to 1 hour for serving. If it thickens too much as it sits, stir gently before spooning onto plates.
Prep ahead: Mix everything together the night before, cover, and refrigerate the insert or transfer the mixture to a covered bowl. Let it sit at room temperature for about 20 minutes before starting the slow cooker the next day for more even cooking.
