Why You’ll Love This Recipe

This recipe is incredibly simple. With four main ingredients and a muffin tin, you can have individual potato gratins that look and taste like you spent hours in the kitchen.

The texture is unforgettable. The potatoes are tender and creamy, the cheese is gooey and golden, and every cup holds together beautifully when you lift it out of the pan.

They are also endlessly adaptable. You can add herbs, garlic, bacon, or a different cheese, or keep them classic and let the creamy potato flavor shine.

Ingredients

2 pounds Yukon Gold or russet potatoes, peeled and sliced paper-thin (about 1/8-inch thick)
1 1/2 cups heavy cream
2 cups shredded Gruyère or sharp cheddar cheese, divided
2 tablespoons unsalted butter, melted

Salt, black pepper, and a pinch of nutmeg are considered free pantry staples and can be added to taste. Optional: fresh thyme or chives for garnish.

Directions

Preheat your oven to 375°F (190°C). Generously grease a 12-cup muffin tin with butter or nonstick spray.
In a medium bowl, whisk together the heavy cream, 1 1/2 cups of the shredded cheese, salt, pepper, and nutmeg if using.
Layer the potato slices in the prepared muffin cups, filling each about halfway. Spoon a little of the cream mixture over the potatoes.
Continue layering with the remaining potato slices, pressing down gently to compact the layers. Pour the remaining cream mixture evenly over the top of each cup.
Sprinkle the remaining 1/2 cup of cheese over the tops. Drizzle with the melted butter.
Cover the muffin tin loosely with aluminum foil and bake for 25 minutes.
Remove the foil and bake for another 15 to 20 minutes, until the potatoes are fork-tender and the tops are golden and bubbly.
Let the cups rest in the pan for 10 minutes before carefully lifting them out with a spoon or small spatula. Garnish with fresh thyme or chives and serve warm.

Variations

Garlic Herb Potato Cups: Add 1 teaspoon garlic powder and 1 teaspoon dried thyme to the cream mixture.
Bacon Cheddar Cups: Sprinkle cooked, crumbled bacon between the layers and use cheddar cheese.
Parmesan Crusted Cups: Use Parmesan instead of Gruyère for a sharper, nuttier finish.
Sweet Potato Cups: Substitute half the potatoes with sweet potatoes and add a pinch of cinnamon.
Spicy Au Gratin Cups: Add a pinch of cayenne pepper or use pepper jack cheese.
Mini Version: Use a mini muffin tin for bite-sized potato cups and reduce the bake time by 5 to 10 minutes.

Expert Tips

Slice the potatoes paper-thin. A mandoline makes this quick and ensures even cooking.
Do not skip the resting time. It helps the layers set so the cups hold their shape when removed from the pan.
Grease the muffin tin generously. The cream and cheese can stick if the pan is not well prepared.
Press the layers down gently. This compacts the potatoes and helps them cook evenly.
Add the final cheese at the end. It creates a golden, bubbly top that holds everything together.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in a 375°F oven for 10 to 12 minutes, or in the microwave for 1 to 2 minutes. For best results, reheat in the oven to restore the crispy top. These cups do not freeze well because the creamy texture can separate upon thawing.

Frequently Asked Questions

Can I use a different cheese? Yes. Gruyère, cheddar, Parmesan, or a blend all work beautifully.
Can I make these ahead of time?Yes. Assemble them, cover, and refrigerate for up to 24 hours. Add 5 to 10 minutes to the covered bake time.
Why did my cups fall apart? They may not have rested long enough, or the layers were not pressed down firmly.
Can I use half-and-half instead of heavy cream? Yes, but the cups will be slightly less rich. Heavy cream gives the creamiest result.
Can I double this recipe? Yes. Use two muffin tins and rotate them halfway through baking.
