Crispy Parmesan Potato Roses Baked in a Muffin Tin Step-by-step instructions

Before you start

Before starting, heat the oven to 400°F (200°C). Scrub the potatoes thoroughly and dry them well. Set up a mandoline or sharp knife for slicing. Grate the Parmigiano-Reggiano if not already grated.

Make the garlic-thyme butter by melting butter and mixing in minced garlic and fresh thyme. Generously butter the muffin tin, including the bottom and sides of each cup. Have a large bowl ready for tossing the potato slices with the butter and cheese.

Instructions

Prep and Assemble

1. 1Prep the potatoes
   Heat the oven to 400°F (200°C). Using a mandoline or a very sharp knife, slice the scrubbed potatoes into 1.5mm-thick rounds. Place the slices in a large bowl and toss with the melted garlic-thyme butter and grated Parmigiano-Reggiano until every slice is evenly coated.
   Look for Potato slices are translucent and evenly coated with butter and cheese.
   Tip Keep the slices in a single layer while tossing to avoid breakage.
2. 2Butter the muffin tin
   Generously butter the cups of a 12-cup muffin tin. Use a pastry brush to coat the bottom and sides of each cup with softened or melted butter, ensuring no spots are missed.
   Look for All muffin cups are well greased.
   Tip Use the same garlic-thyme butter for extra flavor.

At this stage, the potato slices are coated in a glossy mixture of melted butter and grated cheese. The spirals are tightly rolled and fit snugly in the muffin cups, with the cut edges facing up.

The buttered tin ensures they won't stick. The kitchen smells of garlic and thyme, and the raw potato slices look like delicate petals ready to bloom.

Bake to Golden Crisp

3. 3Roll the potato roses
   Take a few potato slices and arrange them in an overlapping row, slightly offset. Roll the row tightly into a spiral to form a rosebud. Place the spiral into a prepared muffin cup, with the cut edges facing up. Repeat with the remaining slices, filling all 12 cups.
   Look for Each cup has a tight spiral of potato slices resembling a rosebud.
   Tip For larger roses, add more slices to each roll; keep them snug in the cup.
4. 4Bake the potato roses
   Place the muffin tin in the oven and bake at 400°F (200°C) for 40 minutes, until the butter bubbles and the top petals open and crisp with amber edges. The bottoms should be deep golden and crisp from the parmesan frico.
   Look for Petals are golden brown and crisp; edges are amber.
   Tip Rotate the tin halfway through for even browning.

After 40 minutes, the butter has bubbled and fried the bottoms into a deep golden frico. The top petals have opened up and curled, with edges turning amber and crisp. The aroma is intensely buttery and nutty, with a hint of toasted cheese. The roses look like golden flowers, and the edges are visibly crisp and slightly curled.

Finish and Serve

5. 5Finish and serve
   Remove the muffin tin from the oven and let it cool for 2 minutes. Use a fork to gently lift each potato rose out of the tin. Sprinkle with flaky salt and fresh rosemary leaves. Serve warm.
   Look for Roses lift out easily and hold their shape.
   Tip If any stick, run a thin knife around the edge before lifting.

The roses lift out of the tin easily, holding their spiral shape. A sprinkle of flaky salt adds a bright, crunchy finish, and fresh rosemary brings a piney aroma. The outer petals shatter when bitten, revealing a tender, creamy center. They are best served warm, when the contrast of crisp exterior and soft interior is at its peak.

Common mistakes

One common mistake is slicing the potatoes too thick, which prevents them from cooking through and crisping properly. Aim for 1.5mm-thick slices. Another issue is not greasing the muffin tin enough, causing the roses to stick. Be generous with butter.

Overcrowding the bowl when tossing can break the slices; handle them gently. Also, avoid opening the oven frequently, as that lets out heat and slows crisping. Finally, let the roses rest for a couple of minutes after baking so they set and release more easily.

How to tell it’s done

The potato roses are done when the tops are deep golden brown and the edges are amber and crisp. The butter should be bubbling and the bottoms should be a rich, dark golden from the parmesan frico.

To test, lift one rose with a fork—it should hold its shape and the outer petals should feel crisp to the touch. If the tops are browning too quickly but the centers are not yet tender, cover loosely with foil and continue baking. The total bake time is 40 minutes at 400°F (200°C).
