There are certain dishes you bring to a cookout expecting them to be popular, and then there are dishes that completely disappear before you’ve even had a chance to go back for seconds.

This 5-Ingredient Slow Cooker Cheesy Hash Brown Casserole definitely belongs in the second category.

I brought it to an end-of-summer neighborhood cookout, and by the time everyone had filled their plates, the slow cooker was practically scraped clean. Even better, three people followed me out to my car afterward because they wanted the recipe.

The secret is how incredibly simple it is. Frozen shredded Potatoes O’Brien eliminate most of the prep, while cheddar cheese, sour cream, condensed cream of chicken soup, and melted butter turn them into a creamy, cheesy casserole with irresistible golden edges.

Best of all, the slow cooker handles almost everything, leaving your oven free for other dishes.

5-Ingredient Slow Cooker End-of-Summer Cookout Crispy Golden Cheesy Hash Brown Casserole

Servings: 10
Prep Time: 10 minutes
Cook Time: 4–5 hours on LOW or 2–3 hours on HIGH

This casserole has everything you want from classic comfort food: tender potatoes, plenty of melted cheddar, a rich creamy sauce, and golden cheesy edges everyone tries to scoop onto their plate.

It’s especially convenient for cookouts and potlucks because you can serve it directly from the slow cooker and keep it warm throughout the meal.

Ingredients

• 1 (30-ounce) bag frozen shredded Potatoes O’Brien
• 2 cups shredded cheddar cheese, divided
• 1 (10.5-ounce) can condensed cream of chicken soup
• 1 cup sour cream
• 4 tablespoons butter, melted

Directions

1. Prepare the slow cooker.
   Lightly grease the inside of a slow cooker to help prevent the potatoes and cheese from sticking.
2. Make the creamy base.
   In a large mixing bowl, combine the condensed cream of chicken soup, sour cream, and melted butter. Stir until smooth and well blended.
3. Add the potatoes and cheese.
   Add the frozen Potatoes O’Brien along with 1½ cups of shredded cheddar cheese. Stir until the potatoes are thoroughly coated with the creamy mixture.
4. Transfer to the slow cooker.
   Spoon the potato mixture into the prepared slow cooker and spread it into an even layer.
5. Add more cheese.
   Sprinkle the remaining ½ cup cheddar cheese evenly over the top.
6. Slow cook.
   Cover and cook on LOW for 4–5 hours or HIGH for 2–3 hours, until the casserole is piping hot and the potatoes are tender.
7. Make the top extra golden, if desired.
   If your slow cooker insert is specifically labeled oven- and broiler-safe, carefully place it under the broiler for about 2–3 minutes, watching closely, until the cheese develops a beautiful golden finish. Otherwise, simply serve it straight from the slow cooker.
8. Rest and serve.
   Allow the casserole to rest for about 10 minutes before serving. This helps the creamy mixture thicken slightly and makes the casserole easier to scoop.

What to Serve With Hash Brown Casserole

This cheesy potato casserole is practically made for summer cookouts. Serve it alongside grilled burgers, beef hot dogs, barbecue chicken, beef ribs, or pulled beef for a hearty spread.

Because the casserole is rich and creamy, lighter sides provide a nice contrast. Try it with:

• Corn on the cob
• Fresh watermelon or mixed fruit
• Garden tomatoes
• Coleslaw
• Green salad
• Baked beans
• Grilled vegetables

Variations & Tips

Want crispier edges?
For slow cooker inserts that are confirmed broiler-safe, a couple of minutes under the broiler can create that irresistible browned cheese on top. Never put a slow cooker insert under the broiler unless the manufacturer specifically says it is safe.

Cooking for picky eaters?
Potatoes O’Brien traditionally contain peppers and onions. If your family prefers something simpler, substitute an equal amount of plain frozen shredded hash browns.

Make it extra cheesy:
Add another ½ cup of shredded cheddar to the potato mixture for an even richer, cheesier result.

Try another condensed soup:
Cream of mushroom or cheddar cheese soup can replace the cream of chicken soup when you want to change the flavor.

Shred your own cheese when possible:
Freshly shredded cheddar usually melts more smoothly than pre-shredded cheese because packaged shredded cheeses often contain anti-caking ingredients.

Make-ahead option:
Combine the ingredients ahead of time and refrigerate them in a covered container. When you’re ready to cook, transfer the mixture to the slow cooker and cook as directed. Avoid putting a refrigerator-cold ceramic insert directly into a hot slow cooker base unless the manufacturer says it is safe.

Keep it warm for parties:
Once the casserole is cooked, switch the slow cooker to the WARM setting for serving. It’s one reason this recipe works so well for potlucks, family gatherings, game days, and neighborhood cookouts.
