Ingredient Additions and Substitutions

This vintage recipe is wonderfully versatile.

Try Different Cheeses

Instead of mild cheddar, use:

• Sharp cheddar
• Colby
• Monterey Jack
• Young Swiss
• Gruyère for a richer flavor

Use Different Potatoes

While russet potatoes create the creamiest texture, you can also use:

• Yukon Gold potatoes
• Red potatoes

Yukon Golds hold their shape especially well.

Make It Lighter

Replace the heavy cream with:

• Half-and-half
• Whole milk mixed with a little cream

The texture will be slightly lighter but still delicious.

Add Fresh Herbs

For extra flavor, stir in:

• Fresh thyme
• Chives
• Parsley
• Rosemary

These additions complement the creamy potatoes beautifully.

How to Make Potato Au Gratin Cups

Step 1: Prepare the Oven

Preheat your oven to 375°F (190°C).

Generously grease a 12-cup muffin tin with butter or oil to help the potato cups release easily.

Step 2: Slice the Potatoes

Peel the potatoes and slice them about ⅛-inch thick or thinner.

A mandoline creates the most even slices, ensuring all the potatoes cook at the same rate.

Step 3: Make the Cream Mixture

In a small bowl, combine:

• Heavy cream
• Minced onion
• Salt
• Black pepper

Stir until well blended.

Step 4: Add the First Layer of Cheese

Divide half of the shredded cheddar evenly among the bottoms of the muffin cups.

This creates the delicious crispy cheese crust.

Step 5: Layer the Potatoes

Arrange the potato slices vertically inside each muffin cup, slightly overlapping as you fill each one.

Press gently to compact the layers.

Step 6: Pour in the Cream

Slowly spoon the seasoned cream over each potato stack.

Allow the liquid to seep between the layers.

Avoid overfilling.

Step 7: Finish with Cheese

Top each potato cup with the remaining cheddar cheese.

This creates the beautifully browned topping.

Step 8: Bake

Place the muffin tin on a baking sheet.

Bake for 35–45 minutes, or until:

• Potatoes are fork tender
• Cheese is bubbly
• Tops are deeply golden brown

Step 9: Let Them Rest

Allow the potato cups to cool in the pan for about 10 minutes.

This helps them firm up for easy removal.

Carefully loosen each cup with a knife or offset spatula before serving.

What to Serve with Potato Au Gratin Cups

These cheesy potato cups pair wonderfully with almost any main course.

Try serving them alongside:

• Roast chicken
• Pork chops
• Grilled steak
• Meatloaf
• Baked ham
• Roast turkey
• Grilled sausages

They also pair beautifully with:

• Green beans
• Roasted Brussels sprouts
• Steamed broccoli
• Garden salad
• Roasted asparagus

For brunch, serve them beside scrambled eggs, bacon, or sausage.

Tips for Perfect Potato Au Gratin Cups

Slice Evenly

Uniform potato slices ensure even cooking.

Don't Skip the Resting Time

The cream thickens as the cups cool slightly, helping them hold together.

Grease the Pan Well

This prevents sticking and makes serving much easier.

Use Freshly Shredded Cheese

Freshly shredded cheese melts more smoothly than pre-shredded varieties.

Bake Until Deeply Golden

The browned cheese adds incredible flavor and texture.
