Potato Au Gratin Cups Recipe (Crispy Cheddar)
These Potato Au Gratin Cups combine paper-thin layers of Yukon Gold potatoes with sharp cheddar and rich heavy cream, baked in a muffin tin until the centers turn silky and tender while the edges crisp to a deep golden brown. Each cup offers a contrast of creamy interior and lacy, caramelized cheese crust. Au gratin is a French technique built around a browned, crusty top, and American cooks have made the potato version a holiday classic. This single-serving take keeps the comfort and adds elegance.

Preparation
Preheat the oven to 375°F. Generously brush a 12-cup muffin tin with melted butter, covering the bottoms and sides of each cup.
Peel the potatoes if desired. Slice them very thinly and evenly, about 1/8 inch thick, using a mandoline with its safety guard or a sharp knife.
Toss the potato slices in a large bowl with the salt and black pepper until evenly seasoned.
Shred the cheddar from a block so it melts smoothly, and keep it in a separate bowl.
Layer a few potato slices into each muffin cup, add a small sprinkle of cheese, and repeat until the cups are nearly full. Press down gently as you go.
Slowly pour a small amount of heavy cream into each cup so it seeps between the layers without covering the tops.
Drizzle any remaining melted butter over the tops of the potato stacks.
Bake for 40 to 50 minutes, until the tops are golden and bubbling. If they brown too quickly, loosely cover the pan with foil.
Test the center of one cup with a thin knife or toothpick. It should slide through easily. Bake 5 to 10 minutes longer if the potatoes are firm.
Let the cups rest in the pan for 5 to 10 minutes so they set.
Run a thin knife around each cup, lift gently out of the tin, and serve warm.

Garlic Potato Au Gratin Cups
Stir 1 minced garlic clove or 1/2 teaspoon garlic powder into the heavy cream before pouring it over the potatoes. The garlic infuses the cream as it bakes, giving every layer a warm, aromatic depth that pairs beautifully with sharp cheddar and roasted meats.
Parmesan Potato Cups
Replace about half of the cheddar with freshly grated Parmesan for a nuttier, more savory flavor. Parmesan also browns beautifully, so you will get an extra crisp, lacy edge around each cup that adds wonderful crunch against the creamy center.
Gruyère Potato Cups
Swap the cheddar for shredded Gruyère to create a more elegant, restaurant-style cup. Gruyère melts into a silky, slightly sweet and nutty layer, which makes this version a showstopper for dinner parties, Christmas dinner, and special Sunday meals.
Herb Potato Cups
Toss chopped fresh thyme, rosemary, chives, or parsley with the potato slices before layering. The herbs perfume the cream as it bakes and add flecks of green that make the finished cups look as fresh as they taste.
Spicy Potato Cups
Add a pinch of cayenne pepper or crushed red pepper flakes to the seasoned potatoes for a gentle kick. The heat plays off the rich cream and cheese, making this version a fun side for grilled chicken or steak.
Chef's Pro Tips
Slice the potatoes thin and even
Slices around 1/8 inch thick cook through at the same rate as the cheese browns. Thicker slices stay firm in the center, while uneven ones leave some layers mushy and others raw. A mandoline gives the best consistency, but always use the safety guard to protect your fingers.
Keep the starch on the potatoes
Do not rinse the sliced potatoes. The surface starch thickens the cream as it bakes and helps the layers cling together, so your cups hold their shape when unmolded instead of sliding apart on the plate.
Shred cheese from a block
Pre-shredded cheese carries anti-caking starch that prevents a smooth melt. Freshly shredded cheddar becomes silky and gooey, and it browns into the crisp, lacy edge that makes these cups so irresistible.
Butter the tin thoroughly
Melted cheese bonds to metal as it cools. A generous coating of butter on the bottoms and sides creates a barrier and also fries the edges slightly, producing a golden, crunchy crust and a clean release every time.
Storage Guide
Room Temperature
Serve the cups warm straight from the oven, and do not leave them out for more than 2 hours. Because they contain cream and cheese, they should be refrigerated promptly after serving. If you are hosting a buffet, keep them on a warm platter and replace with fresh batches as needed.
Refrigerator
Cool the cups completely, then store them in an airtight container for up to 3 days. For best results, separate layers with parchment paper. Reheat in a 350°F oven for 10 to 15 minutes until hot throughout, or use an air fryer to bring back the crispy edges.
Freezer
You can freeze the baked cups, though the texture may soften slightly after thawing. Wrap them individually, place in a freezer bag, and freeze for up to 2 months. Thaw overnight in the refrigerator, then reheat in a 350°F oven until hot and the edges have crisped again.
Avoid These Mistakes
✕ Slicing the potatoes too thick
Thick slices stay hard in the center while the cheese on top darkens. Aim for about 1/8 inch and use a mandoline if you can. If you only have a knife, slice slowly and check that the pieces look consistent before layering.
✕ Overfilling the muffin cups
Packing the potatoes above the rim causes cream and cheese to overflow and burn on the oven floor. Fill the cups nearly full but leave a little room, since the potatoes shrink as they cook. Placing a baking sheet on the rack below catches any drips.
✕ Unmolding too soon
Pulling the cups out right after baking makes them collapse because the cheese and cream have not set. Wait 5 to 10 minutes, then run a thin knife around the edges. This short rest is the secret to cups that stand tall on the plate.
✕ Skimping on the butter
A dry tin lets cheese weld itself to the metal, and the cups tear when lifted. Brush every cup thoroughly with melted butter, covering the bottom and sides, to guarantee a clean release and a golden crust.

Frequently Asked Questions
What potatoes are best for Potato Au Gratin Cups? expand_more
Yukon Gold potatoes are my top choice because their medium starch and buttery flavor create a creamy, tender texture while still holding their shape. Russet potatoes also work well and bake up softer and fluffier, with more starch to thicken the cream. Whichever you choose, slice them thinly and evenly, about 1/8 inch thick, so every layer cooks through at the same rate.
Can I use a different cheese in these cups? expand_more
Absolutely. Sharp cheddar gives the classic tangy flavor, but Gruyère, Swiss, Monterey Jack, Parmesan, and mozzarella all melt well and work beautifully. For the best flavor and crisp edges, try a blend, such as cheddar with a little Parmesan. Always shred the cheese from a block, since pre-shredded cheese contains starch that can keep it from melting smoothly.
Why are my potatoes still hard after baking? expand_more
The most common cause is slices that are too thick or uneven. Thicker pieces need more time to soften, while thin, uniform slices cook through evenly. If the tops are already golden, loosely cover the pan with foil and bake another 5 to 10 minutes until a knife slides through easily. A mandoline makes consistent slicing much easier next time.
Why did my potato cups fall apart when I removed them? expand_more
Usually the cups were not rested long enough. As they cool for 5 to 10 minutes, the melted cheese and cream set and bind the layers together. Also make sure the muffin tin is generously buttered and run a thin knife around each cup before lifting. Pressing the layers down gently while assembling also helps them stay compact.
Can I make these without heavy cream? expand_more
Yes, whole milk is the easiest substitute and will still produce tender, cheesy cups. Expect a slightly less rich and creamy result, since heavy cream has more fat and resists curdling in the oven. If you use milk, an extra sprinkle of cheese between the layers helps keep the cups flavorful and cohesive.
