Ingredients

Makes one 9×13-inch gratin (serves 6–8)

• 3 lbs Yukon Gold potatoes (about 6 medium), peeled or scrubbed if you prefer the skins on
• 2 cups heavy cream (or 1 cup heavy cream + 1 cup whole milk for a lighter touch)
• 2 cloves garlic, minced
• 2 tbsp unsalted butter, melted (plus extra for the dish)
• 1 tsp kosher salt, plus extra to taste
• 1/2 tsp freshly ground black pepper
• Pinch of freshly grated nutmeg (optional, but lovely)
• 1 1/2 cups grated Gruyère cheese
• 1/2 cup grated Parmesan cheese, plus extra for sprinkling
• 1–2 sprigs fresh thyme, leaves removed (or 1/2 tsp dried thyme)
• Optional: 4 slices cooked bacon, chopped; 1 small onion, thinly sliced and caramelized; chopped chives for serving

Notes: If you’re following specific dietary needs, swap heavy cream for half-and-half or use a plant-based cream for a dairy-free version (results will differ).

Tools You’ll Want

• Mandoline or very sharp chef’s knife
• 9×13-inch baking dish (or a 2-quart gratin dish)
• Mixing bowl, small saucepan, and a microplane for nutmeg (if using)
• Aluminum foil and a baking sheet to catch any drips

Step-by-Step Directions

1. Preheat and prep. Preheat your oven to 375°F (190°C). Butter the baking dish well so the potatoes don’t stick and the edges get nicely golden.

2. Slice the potatoes. Using a mandoline or a sharp knife, slice the potatoes about 1/8-inch thick. Uniform thickness is the secret to even cooking; think thin coins, not chips. Rinse the slices briefly and pat dry with a kitchen towel to remove excess starch.

3. Warm the cream. In a small saucepan, combine the heavy cream (or cream + milk), minced garlic, salt, pepper, and nutmeg. Warm gently over medium heat until it’s steaming and the garlic smells fragrant—don’t boil. Stir in the thyme leaves, then remove from heat.

4. Layer the gratin. Arrange a single layer of potato slices in the buttered dish, slightly overlapping like shingles. Sprinkle a little Gruyère and Parmesan over the layer (about 1/3 of the total cheese). Pour a couple of ladles of the warm cream mixture over the potatoes so it starts to settle into the layers.

5. Repeat. Continue layering potatoes, cheese, and cream, finishing with a generous sprinkle of Gruyère and Parmesan on top. Brush the top with the 2 tbsp melted butter — this helps the top get that irresistible golden crust.

6. Cover and bake. Cover the dish tightly with foil and bake for 35 minutes. This lets the potatoes start to soften without the top burning.

7. Uncover and finish. Remove the foil and bake another 25–30 minutes, or until the top is deeply golden and the potatoes are tender when pierced with a knife. If the cheese browns too quickly, loosely tent with foil.

8. Rest then serve. Let the gratin rest 10–15 minutes before serving. This helps the cream set so the slices hold together beautifully. Garnish with chives, extra thyme, or chopped bacon if you used it.

Serving suggestion: Serve alongside roasted chicken, pork tenderloin, or a crisp green salad for a balanced meal. For a cozy family dinner, pair with simple roasted Brussels sprouts or try the country twist in this Country Ranch Green Beans and Potatoes with Bacon.

Cooking Tips (from my kitchen to yours)

• Slice even, slice thin: A mandoline is a busy mom’s best friend here. If you don’t have one, take your time with a sharp knife. Thinner slices equal creamier layers.
• Don’t skimp on cheese: Gruyère gives that nutty, melty goodness; Parmesan adds sharpness. Together they’re magic.
• Make it ahead: Assemble the gratin, cover, and refrigerate up to 24 hours. Add 10–15 minutes to the covered baking time straight from the fridge.
• Leftover hero: Reheat single servings in the oven at 350°F (175°C) for 15–20 minutes or microwave gently for a quick fix.
• For a crispier top: After uncovering, broil for 1–2 minutes, watching closely so it doesn’t burn.
• Swap-ins: If you don’t have Gruyère, Emmental or Jarlsberg are decent substitutes. For a sharper bite, a portion of aged cheddar can work.

Don’t worry if your cream seems a little thin when you assemble — it will thicken as the potatoes release starch and the whole dish bakes. That’s kitchen chemistry doing its happy work.

Personal Note from Anna

My sister Patricia and I perfected this gratin over countless family dinners and holiday experiments. Once, during a chaotic Thanksgiving, I accidentally doubled the garlic. To my surprise, no one complained — they raved. That’s when I learned that good food forgives mistakes, and so does family. This dish became our go-to for potlucks because it looks impressive but is forgiving to make.

FAQs

Q: Can I use russets instead of Yukon Golds?
A: Yes. Yukon Golds are creamier and hold their shape well, but russets will work if you prefer a fluffier texture. Just watch for slightly longer bake time.

Q: Can I make this dairy-free or lighter?
A: Try full-fat coconut milk or a plant-based cream for dairy-free. For lighter, use half-and-half or a mix of milk and a little cream. The texture will vary, but flavors remain comforting.

Q: How do I prevent the top from burning while the potatoes finish cooking?
A: Cover with foil for most of the bake time, then uncover to brown the top near the end. If browning too fast, tent with foil.

Q: Can I freeze potato gratin?
A: You can freeze it before baking (assembled) for up to 1 month. Thaw overnight in the fridge before baking. Baked leftovers freeze okay but can change texture.

Q: What are some nice add-ins?
A: Caramelized onions, chopped cooked bacon, a sprinkle of paprika, or fresh herbs like rosemary or thyme.

Pairing and Presentation

This gratin is the perfect partner for roasted or braised mains: think herb-roasted chicken, beef brisket, or pork loin. For a lighter meal, plate a generous scoop with a crisp salad and a simple vinaigrette. Garnish with fresh herbs and a few grinds of black pepper for a restaurant-worthy finish without the fuss.

If you’re bringing this to a potluck, cover the dish during transport and keep it warm in a low oven if possible. It reheats beautifully and is always one of the first dishes to vanish.
