The Ingredients

This recipe uses simple, affordable ingredients that come together beautifully.

3 large russet potatoes, peeled – For crispy, golden potato cups.
6 tablespoons unsalted butter, melted – For richness and golden crispiness.
1 teaspoon salt – Balances the flavors.

Step-by-Step Instructions

Step 1: Preheat and Prep

Preheat the oven to 375°F. Generously brush a standard 12-cup muffin tin with a little of the melted butter.

Pro Tip: Grease the muffin tin well so the potato cups release easily.

Step 2: Slice the Potatoes

Slice the potatoes very thin, about ⅛ inch thick, so they will bend easily and crisp at the edges.

Pro Tip: Use a mandoline slicer for uniform, paper-thin slices.

Step 3: Coat the Potatoes

Toss the potato slices in a bowl with the remaining melted butter and salt until evenly coated.

Pro Tip: Make sure every slice is coated in butter for maximum crispiness.

Step 4: Line the Muffin Cups

Line each muffin cup with overlapping potato slices, pressing them against the bottom and up the sides to form little cups.

Pro Tip: Overlap the slices slightly and press them firmly against the sides of the cup.

Step 5: Bake to Golden Perfection

Bake for 30 to 35 minutes, or until the edges are deeply golden and crisp and the centers are tender.

Pro Tip: Watch the edges—they’ll brown first. That’s where the crispiness is.

Step 6: Cool and Serve

Let the potato cups rest in the pan for 5 minutes, then carefully lift them out and serve warm.

Pro Tip: Use a small spoon or fork to gently lift the cups out of the pan.

Frequently Asked Questions

Can I use a different type of potato?
Yes. Yukon Gold, red potatoes, or sweet potatoes all work beautifully.

Can I use olive oil instead of butter?
Yes. Olive oil works beautifully, but butter adds richer flavor.

Can I make these ahead of time?
Yes. Assemble the potato cups, cover, and refrigerate for up to 4 hours. Bake as directed, adding a few minutes if needed.

How long do leftovers last?
