Equipment You’ll Need

• Standard 12-cup muffin tin
• Mandoline slicer or a very sharp knife
• Large mixing bowl
• Small saucepan
• Pastry brush
• Cutting board

Ingredients

• 2 lbs (about 4 medium) Russet or Yukon Gold potatoes, washed
• 1/2 cup (1 stick) unsalted butter, melted
• 2 cloves garlic, minced
• 1 tablespoon fresh thyme leaves (or 1 teaspoon dried)
• 1/2 cup grated Parmesan cheese
• 1 teaspoon kosher salt
• 1/2 teaspoon freshly ground black pepper
• Optional for garnish: fresh chives or parsley, chopped

Instructions

1. Preheat your oven to 375°F (190°C). Generously grease a standard 12-cup muffin tin with butter or non-stick spray. This is a crucial step to prevent sticking.
2. Wash the potatoes thoroughly. There is no need to peel them, as the skin adds a nice texture and flavor. Using a mandoline slicer on its thinnest setting (about 1/16 inch), carefully slice the potatoes into uniform rounds. If you don’t have a mandoline, use a very sharp knife and slice as thinly and evenly as possible.
3. Place the potato slices in a large bowl. It’s important not to rinse them after slicing, as the starch helps the layers stick together.
4. In a small saucepan over low heat, melt the butter. Stir in the minced garlic and thyme leaves, and let it cook for about a minute until fragrant. Be careful not to burn the garlic.
5. Pour the melted garlic-thyme butter over the potato slices in the bowl. Add the grated Parmesan cheese, kosher salt, and black pepper.
6. Using your hands, gently toss everything together until each potato slice is evenly coated with the butter mixture and seasonings.
7. Begin stacking the coated potato slices one by one into the prepared muffin cups. Fill each cup to the top, pressing down slightly to compact the layers. The stacks will shrink a bit as they bake.
8. Bake for 50-60 minutes, or until the tops are deep golden brown and the edges are crispy. The potatoes in the center should be tender when pierced with a knife.
9. Let the potato stacks cool in the muffin tin for at least 5 minutes. This allows them to set and makes them easier to remove. To remove, run a small offset spatula or butter knife around the edge of each stack and gently lift it out.
10. Garnish with fresh chives or parsley, if desired, and serve immediately while hot and crispy.

Expert Cooking Tips

• Uniformity is Key: A mandoline slicer is highly recommended for this recipe. Slicing the potatoes to a consistent, paper-thin thickness ensures even cooking and the perfect texture.
• Don’t Rinse Slices: The natural starch on the cut potatoes acts as a binder, helping the layers fuse together as they bake. Rinsing will wash it away.
• Press Them Down: For more compact and stable stacks, use the back of a spoon to gently press down on the tops of the stacks about halfway through the baking time.
• Don’t Skimp on Fat: The butter is essential not only for flavor but also for crisping the potatoes and preventing them from sticking. Ensure every slice is well-coated.
• Check for Doneness: Ovens vary. Start checking around the 45-minute mark. The visual cue is key: you want deep golden-brown tops and visibly crispy, darker edges.

Substitutions and Variations

For a different flavor profile, swap out the cheese and herbs. Gruyère, aged cheddar, or Pecorino Romano work beautifully instead of Parmesan. Rosemary or sage can be used in place of thyme. For a dairy-free version, use high-quality olive oil or a vegan butter substitute and a nutty nutritional yeast blend instead of cheese. Sweet potatoes can also be used, but you may need to adjust the baking time slightly as they cook faster.

Common Mistakes to Avoid

The most common mistake is slicing the potatoes too thick or unevenly, which results in undercooked centers and less crispy stacks. Another pitfall is not greasing the muffin tin adequately, making the stacks difficult to remove without breaking. Finally, under-seasoning is a frequent error; potatoes require a generous amount of salt to bring out their flavor, so don’t be shy with the salt and pepper.

Serving Suggestions

These potato stacks are a versatile side dish that pairs wonderfully with roasted chicken, pan-seared steak, or a delicate piece of baked fish. They can also be the star of the show as an appetizer. Serve them on a platter with a side of garlic aioli, chive-infused sour cream, or a simple ketchup for a crowd-pleasing starter.

Storage and Reheating Tips

Leftover potato stacks can be stored in an airtight container in the refrigerator for up to 3 days. To reheat and restore their crispy texture, place them on a baking sheet in a 375°F (190°C) oven or in an air fryer for 5-10 minutes until heated through and crisp again. Avoid reheating in the microwave, as it will make them soft and soggy.

Frequently Asked Questions

Can I make these potato stacks ahead of time?

Yes, you can assemble the stacks in the muffin tin a few hours ahead of time. Cover with plastic wrap and refrigerate. Note that the potatoes may oxidize slightly. For best results, bake them just before serving. You can also bake them completely and then reheat them in the oven or air fryer before serving.

Do I have to use a muffin tin?

The muffin tin is ideal because it gives the stacks their signature shape and helps them cook evenly with crispy sides. If you don’t have one, you could try free-form stacks on a parchment-lined baking sheet, but they may not hold their shape as well.

Why are my potato stacks sticking to the pan?

This is usually due to not greasing the muffin tin sufficiently. Be very generous with butter or non-stick spray, ensuring you coat the bottom and all sides of each cup. Also, letting them cool for at least 5 minutes in the pan before attempting to remove them helps them release more easily.
