I serve this Cheesy Potato Gratin for two because it delivers ridiculously silky, cheesy layers that will have you arguing over the last spoonful.

Jump to Recipe

I’m obsessed with this Cheesy Potato Gratin because I screwed up dinner and ended up with something ridiculous. I was juggling a million things, burned the pan I meant to serve, and grabbed a couple of potatoes and a cheese I liked.

The melted Gruyere and the smashed garlic clove turned into this ridiculously creamy, slightly crunchy bake that fed two and felt like a small victory. It’s stupidly simple, meant for Easy Meals For Two but fancy enough to pretend I planned it.

Honestly, I make it when I’m tired, proud, and hungry all at once, and slightly smug.

Yukon Gold potatoes: creamy texture, holds up in baking, thin slices get perfectly tender.
Heavy cream: rich, silky sauce that makes everything luxurious and a little sinful.
Whole milk: lightens the cream, keeps sauce smooth without being too heavy.
Gruyere or Fontina: melty, nutty cheese that pulls and tastes grown-up.
Parmesan: sharp salty edge, adds bite and a little crunchy top crust.
Unsalted butter: adds richness and helps everything brown nicely, cozy comfort food vibes.
Garlic: bright, savory punch, not overpowering when minced or smashed.
Thyme: herbal lift, adds an earthy note that cuts the richness.
Kosher salt: seasons through the layers, makes flavors pop, don’t skip it.
Black pepper: warm kick, keeps the dish from tasting flat.
Nutmeg: subtle warm hint, optional but it ties the creamy notes together.

Ingredient Quantities

2 medium Yukon Gold potatoes, about 1 lb, peeled or not peeled, sliced thin-ish

3/4 cup heavy cream

1/4 cup whole milk

3/4 cup grated Gruyere or Fontina, packed

2 tbsp grated Parmesan, loosely packed

1 tbsp unsalted butter plus a little extra to grease the dish

1 small garlic clove, minced or smashed

1 tsp fresh thyme leaves or 1/2 tsp dried thyme

1/2 tsp kosher salt, more to taste

1/4 tsp freshly ground black pepper

Pinch of freshly grated nutmeg, optional but great

How to Make this

Print Recipe (No Advertisments)

1. Preheat oven to 375°F and lightly butter a small oval or 8×6 inch baking dish.

2. Thinly slice the potatoes about 1/8 inch thick, try to keep them similar so they cook evenly; no need to be perfect.

3. In a small saucepan melt 1 tablespoon butter over low heat, add the minced garlic and thyme and stir for 30 seconds until fragrant, don’t let it brown.

4. Pour in the heavy cream and whole milk, warm until just below simmering, stir in the pinch of nutmeg if using, and remove from heat.

5. Toss the sliced potatoes with 1/4 teaspoon black pepper and 1/2 teaspoon kosher salt so the seasoning starts to get into the layers.

6. Layer about half the potatoes in the dish, sprinkle half the grated Gruyere/Fontina and half the Parmesan over them, then pour about half the warmed cream mixture over this first layer.

7. Repeat with the remaining potatoes and cheeses, pour the rest of the cream so the liquid comes up between the slices but doesn’t completely drown them; press down gently to compact.

8. Dot the top with a little extra butter, cover tightly with foil and bake for 35 to 40 minutes until the potatoes are tender when poked with a knife.

9. Remove the foil, switch oven to broil or raise temp to 425°F and brown the top for 4 to 6 minutes until golden and bubbly, watch it close so it doesn’t burn.

10. Let the gratin rest 10 minutes before serving so it sets, taste and add a little more salt if needed.

Equipment Needed

1. 8×6 inch oval baking dish or similar small casserole, buttered well
2. sharp chef’s knife and cutting board for slicing potatoes
3. mandoline or a good vegetable peeler and steady hand for even 1/8 inch slices
4. small saucepan to warm cream and infuse garlic and thyme
5. mixing bowl and tongs or fork to toss potatoes with salt and pepper
6. box grater for the Gruyere/Fontina and Parmesan
7. foil to cover the dish for baking and an oven mitt to handle hot pans
8. spoon or spatula to press layers down and a knife to test doneness

FAQ

Q: Can I use russet or red potatoes instead of Yukon Golds?

A: Yes. Yukon Golds are creamier and hold together well, but russets give a fluffier texture and reds stay firmer. Slice them all about the same thickness so they cook evenly.

Q: How thin should the slices be and do they need to be rinsed or soaked?

A: Slice around 1/8 to 1/4 inch thick. No need to soak unless you want to remove extra starch for a slightly less gluey texture. If you do rinse, dry the slices so the cream clings better.

Q: Can I make this ahead and reheat it?

A: Totally. Assemble and refrigerate up to 24 hours, then bake a little longer from cold (add 10 to 15 minutes). For leftovers, cover and reheat at 350F until warmed through, or crisp the top under the broiler for a minute or two, watching closely.

Q: What cheese can I swap for Gruyere or Fontina?

A: Emmental, Comte, mild cheddar, or a mix of mozzarella and a sharper cheese will work. You want a melty cheese with good flavor. Keep a small amount of Parmesan or Pecorino for that salty crust note.

Q: How do I get a golden, bubbly top without burning the potatoes?

A: Bake at a moderate temp so potatoes cook through, around 350 to 375F. If the top is browning too fast, tent foil loosely and finish uncovered for the last 5 minutes. For extra browning, hit it under the broiler for 30 to 90 seconds while watching.

Q: Can I make this lighter or dairy free?

A: For lighter, use half-and-half or a mix of milk and a little cream, but the texture will be less rich. For dairy free, use full fat coconut milk or a creamy oat milk plus a dairy free shredded cheese that melts decently. Flavor and mouthfeel will change, but it still works.

Cheesy Potato Gratin For Two Recipe Substitutions and Variations

Potatoes: if you prefer a starch swap, use russets for a fluffier, crispier edge, or sweet potatoes for a sweeter, earthier gratin; note sweet potatoes will change cooking time and flavor a lot.
Cream + milk: use 1 cup half and half instead of the cream+mile combo, or stir 2 tbsp melted butter into 3/4 cup whole milk to mimic richer creaminess.
Gruyere/Fontina: swap with sharp cheddar for a bolder flavor, or Emmental/Swiss for a similar nutty melt; asiago also works if you like tang.
Parmesan: Pecorino Romano is a good stand in if you want saltier, sharper notes, or use finely grated Manchego for a milder, buttery finish.

Pro Tips

1) Slice the potatoes as evenly as you can, use a mandoline if you got one. If you dont, stack the slices and cut slowly with a sharp knife. Even thickness means everything cooks at the same time so you wont end up with mushy bits and undercooked bits.

2) Warm the cream with the garlic and thyme but dont let it boil. Boiling can make the cream separate or scorch the garlic and give a bitter taste. Warm until it just starts to steam, then pull it off the heat.

3) Salt between layers, not just on top. Tossing the slices lightly with salt early helps the seasoning sink in, and you can always add a pinch more after it rests. Remember cheeses are salty too so taste before over-salting.

4) Give it time to rest after baking. Letting the gratin sit 10 minutes makes it set so you can slice clean portions, and it actually finishes cooking gently while it cools. If you need to make it ahead, reheat covered in a low oven until warmed through, then broil a minute to refresh the top.
