½ teaspoon salt: Enhances the natural flavor of the potatoes. Adjust to taste.
You'll also need a standard 12-cup muffin tin.
How to Make 3-Ingredient Crispy Potato Cups
Step 1: Preheat the Oven
Preheat your oven to 400°F (200°C). Lightly grease a 12-cup muffin tin with butter or cooking spray, making sure to coat the bottoms and sides.
Greasing the tin well helps prevent the potatoes from sticking and makes the finished cups easier to remove.
Step 2: Slice the Potatoes
Wash and dry the potatoes. Peel them if you prefer, although leaving the skins on can add texture and save preparation time.
Slice the potatoes very thinly, about ⅛ inch thick. A mandoline slicer makes this easier, but a sharp knife works too. Try to keep the slices similar in thickness so they cook evenly.
Place the slices in a bowl and toss them with the melted butter and salt until each piece is lightly coated.
Helpful tip: If you rinse the slices to remove excess starch, dry them thoroughly before adding the butter. Extra moisture can prevent the edges from becoming crisp.
Step 3: Arrange the Potato Cups
Place the potato slices into each muffin cup, overlapping them in a circular pattern. Continue layering until each cup is filled, then gently press the potatoes down.
The slices will shrink slightly as they cook, so it's fine to fill each muffin cup generously.
For the crispiest results, avoid packing the slices into a solid, tightly compressed mass. A little space between layers allows heat to circulate.
Step 4: Bake Until Golden and Tender
Bake for 40–50 minutes, checking toward the end of the cooking time. The exact time depends on the thickness of the slices, the type of potato, and your oven.
The potato edges should look golden brown and crisp, while the centers should be tender when pierced with a knife.
If the tops brown too quickly before the centers are cooked, loosely cover the muffin tin with foil for the remaining baking time.
Step 5: Rest and Remove
Let the potato cups rest in the muffin tin for about 5 minutes after baking. Carefully loosen the edges with a small silicone spatula or butter knife, then lift each cup out.
Serve them while they're hot for the best contrast between crispy edges and soft centers.
Tips for Extra-Crispy Potato Cups
Slice evenly. Thin, uniform slices cook more consistently than thick or uneven pieces.
Dry the potatoes well. Excess moisture creates steam, which can make the finished cups softer.
Use enough fat to coat the slices. Butter adds flavor and encourages browning, but the potatoes shouldn't be swimming in it.
Don't rush the baking. The centers need enough time to soften while the outer layers become golden.
Let them rest briefly. A few minutes in the tin helps the cups hold their shape when removed.
Easy Variations to Try
The three basic ingredients make a delicious starting point, but you can easily adapt the recipe.
Cheesy potato cups: Sprinkle a little grated cheddar or Parmesan over the cups during the final 5–10 minutes of baking.
Garlic and herb: Add a small amount of garlic powder and dried rosemary or thyme to the butter.
Smoky paprika: Toss the slices with a pinch of smoked paprika for a warm, savory flavor.
Parmesan crust: Add finely grated Parmesan between a few of the potato layers for extra flavor and browning.
Sweet potato cups: Replace the regular potatoes with sweet potatoes. Slice them evenly and check for tenderness, as their texture and cooking time may differ.
Keep in mind that cheese and additional seasonings turn this into a variation rather than the original three-ingredient version.
What to Serve With Potato Cups
These little potato cups are versatile enough for breakfast, lunch, dinner, or appetizers.
For breakfast, serve them with scrambled eggs, omelets, or sautéed vegetables. At dinner, they pair well with roast chicken, grilled fish, meatloaf, or steak.
For a snack or party platter, offer them with sour cream, garlic yogurt sauce, ketchup, or a simple herb dip.
You can also serve them alongside a green salad to balance the richness of the potatoes and butter.
Make-Ahead, Storage, and Reheating
Make ahead: You can slice the potatoes shortly before baking, but they may discolor if left exposed to air. If you prepare them in advance, keep them covered in cold water in the refrigerator, then drain and dry them thoroughly before seasoning and baking.
Storage: Refrigerate leftover potato cups in an airtight container within 2 hours of cooking. For best quality, eat them within 3–4 days.
Reheating: Place them on a baking sheet in a 375°F (190°C) oven for about 8–12 minutes, or until heated through and crisp again. An air fryer also works well. Microwaving is possible, but the potatoes will usually be softer.
Freezing: The cups can be frozen, although their texture may change after thawing. Reheat them from frozen in the oven or air fryer until hot throughout.
Frequently Asked Questions
Can I make these potato cups without butter?
Yes. Olive oil or another cooking oil can replace the butter. Use enough to lightly coat the potato slices so they brown and release from the muffin tin more easily.
Why did my potato cups turn out soggy?
The slices may have been too wet, too thick, or packed too tightly. They may also need more baking time. Dry the potatoes thoroughly and bake until the centers are tender and the edges are golden.
Do I need to peel the potatoes?
No. Potato skins are edible, and leaving them on saves time. Wash and scrub the potatoes thoroughly before slicing.
Can I prepare these in an air fryer?
Possibly, if you have heat-safe individual molds that fit your air fryer basket. Cooking time will depend on the appliance and the thickness of the slices, so check frequently for browning and tenderness.
How do I stop the cups from sticking to the muffin tin?
Grease the wells thoroughly, including the sides. Let the cups rest for a few minutes after baking, then gently loosen the edges before lifting them out.
