How to Make the Recipe

Step 1: Preheat Oven

Preheat your oven to 350°F (175°C) and grease a baking dish with butter or cooking spray.

Step 2: Prep the Cream Mixture

In a bowl, combine cream, minced garlic, melted butter, salt, pepper, and thyme leaves (if using).

Step 3: Slice the Potatoes

Peel and thinly slice the potatoes (about 1/8 inch thick) using a sharp knife or mandoline.

Step 4: Layer the Potatoes

Arrange a layer of potatoes in the dish. Pour over some cream mixture and sprinkle with cheese. Repeat layers until ingredients are used up, finishing with cheese on top.

Step 5: Bake

Cover with foil and bake for 50 minutes. Remove foil and bake another 20–30 minutes until golden and bubbly.

Step 6: Rest and Serve

Let rest for 10 minutes before serving to allow the cream to thicken and flavors to meld.

Tips for Making the Recipe

• Use starchy potatoes like Russet or Maris Piper for the creamiest result.
• Slice potatoes evenly to ensure even cooking throughout the dish.
• Grate cheese yourself—pre-shredded varieties often contain anti-caking agents that affect melting.
• Season each layer lightly to ensure full flavor in every bite.
• Let it rest before serving so it holds its shape better when sliced.

How to Serve

Serve warm as a side dish with roast beef, lamb, chicken, or even a baked salmon. It also makes a lovely vegetarian main with a crisp green salad or roasted vegetables. For a fancier touch, garnish with fresh thyme or chives just before serving.

Make Ahead and Storage

Storing Leftovers

Store cooled leftovers in an airtight container in the fridge for up to 4 days.

Freezing

Wrap tightly and freeze for up to 1 month. Thaw overnight in the fridge before reheating.

Reheating

Reheat in the oven at 350°F (175°C) until warmed through, or microwave in short intervals, covering to retain moisture.

FAQs

1. Can I make potatoes gratin ahead of time?

Yes! Assemble the dish, cover, and refrigerate up to a day ahead. Bake when ready to serve.

2. What’s the best potato for gratin?

Starchy potatoes like Russet, Maris Piper, or Sebago give the best creamy texture.

3. Can I use milk instead of cream?

You can, but it will be less rich. Whole milk or half-and-half are better than low-fat milk.

4. Why is my gratin watery?

Too much moisture from low-starch potatoes or insufficient baking time can cause this—use the right potatoes and bake uncovered for the last 20–30 minutes.

5. How do I slice potatoes thinly?

Use a mandoline slicer for even, paper-thin slices.

6. Can I add onions to this dish?

Absolutely—thinly sliced onions can be layered in for extra flavor.

7. What cheese melts best in gratin?

Gruyère melts beautifully and adds nutty flavor, but cheddar or Colby are great too.

8. Can I make this gluten-free?

Yes, this recipe is naturally gluten-free as long as your cheese and cream are gluten-free.

9. Do I need to peel the potatoes?

Peeling is recommended for the creamiest texture, but leaving the skin on adds a rustic touch.

10. How do I get the top golden and crispy?

Bake uncovered at the end or broil for 2–3 minutes to achieve a bubbly, browned top.
