Step 4: Add More Cheese

Sprinkle the remaining cheese evenly over the tops of the potato stacks.

This final layer of cheese will melt and create a beautiful golden crust during baking.

Step 5: Bake the Potato Stacks

Cover the muffin tin loosely with aluminum foil.

Place the pan in the preheated oven and bake for 30 minutes.

After 30 minutes, remove the foil and continue baking for another 20 to 25 minutes, or until the potatoes are fork-tender and the tops are golden brown.

The edges should become slightly crispy while the centers remain creamy and soft.

Step 6: Cool and Remove

Remove the muffin tin from the oven and allow the potato stacks to cool for about 5 minutes.

Carefully run a knife around the edges of each stack if necessary, then gently lift them out of the muffin cups.

The brief cooling period helps the stacks hold their shape.

Serving Suggestions

These Au Gratin Potato Stacks pair beautifully with:

  • Roasted chicken
  • Grilled steak
  • Pork tenderloin
  • Baked ham
  • Turkey dinners
  • Holiday meals

Serve them warm for the best texture and flavor.

Tips for Success

Slice Evenly

Thin, consistent potato slices ensure even cooking and a tender texture throughout.

Choose the Right Cheese

Gruyère provides a rich, nutty flavor, while sharp cheddar offers a more familiar cheesy taste. Either works wonderfully.

Don’t Skip the Cooling Time

Allowing the stacks to rest for a few minutes makes them easier to remove from the muffin tin without falling apart.

Use Freshly Shredded Cheese

Freshly shredded cheese melts more smoothly than pre-packaged varieties and creates a creamier result.

Variations

Although the basic recipe uses only four ingredients, you can customize it with additional flavors:

  • Add minced garlic for extra richness.
  • Sprinkle fresh thyme or rosemary between layers.
  • Include a pinch of black pepper.
  • Add cooked bacon bits for a smoky twist.
  • Mix different cheeses for deeper flavor.

Storage and Reheating

Store leftover potato stacks in an airtight container in the refrigerator for up to 3 days.

To reheat, place them in a 350°F (175°C) oven for 10 to 15 minutes until heated through. This method helps restore their crispy edges.
