slow cooker Au Gratin Potatoes Recipe
Potatoes au gratin have always been a favorite in my home, but now they can be made in the slow cooker! Not only is this great news for summertime (tasty potatoes without heating up the kitchen with the oven), but it’s also a great option for the holidays.
When you’re preparing a few dishes for a big holiday meal, oven space is a precious commodity. Save that space for Roasted Vegetables, Sweet Potato Casserole, or Cornbread Dressing, and let the slow cooker work its magic on the potatoes!
Ingredients
- Gold Potatoes: Use a mandolin slicer for even slices. Russet potatoes work.
- Seasoned Salt and Pepper: Adjust these to taste as you build the sauce.
- Unsalted Butter: Use unsalted to control the overall saltiness of the dish.
- Garlic and Onion Powder: Have prepped before cooking so they’re ready to go.
- All-Purpose Flour: Thickens the sauce, giving it a creamy consistency.
- Milk: Whole milk works best, but if using a lower fat option, consider adding a touch more butter.
- Sour Cream: Use full-fat to prevent the sauce from breaking under heat.
- Cheddar Cheese: Look for sharp or extra sharp and shred your own cheese.
- skippable Fresh Parsley or Chives: Add just before serving to keep herbs fresh.

The Secret To slow cooker Au Gratin Potatoes
Here’s my secret for making these potatoes soft inside and crispy on the edges:
Put a few layers of paper towels on top of the slow cooker! The towels soak up steam, which helps the potatoes crisp up nicely.
If you can, swap out the towels halfway through cooking. If you forget, don’t worry!
After cooking, leave the lid off for a little while while keeping the heat on. This helps the tops get a bit crispier.
