Gather Your Potato Gratin Ingredients

Here’s what you’ll need to create this delicious creamy dish:

1.5 kg (3.3 lbs) Yukon Gold or russet potatoes, peeled and thinly sliced
2 medium garlic cloves, minced
85 g (3 oz) finely grated Gruyère cheese
60 g (2 oz) finely grated Parmigiano-Reggiano cheese
2 teaspoons fresh thyme leaves (or 1 teaspoon dried thyme)
460 ml (2 cups) whipping cream (heavy cream)
2 tablespoons unsalted butter, softened (for greasing the dish)
Salt and freshly ground black pepper, to taste

Step-by-Step Recipe for Potato Gratin

Follow these steps to create your delicious gratin:

Preheat your oven to 200°C (400°F). Grease a casserole dish with softened butter.
In a bowl, mix the Gruyère and Parmigiano-Reggiano cheeses. Reserve about a third of this cheese for the topping.
Add the minced garlic to the cheese mixture and stir well.
Next, stir in the thyme leaves and pour in the whipping cream. Season with salt and pepper, and whisk until everything is combined.
Toss the sliced potatoes in the cream mixture until they are well coated.
Pack the coated potatoes tightly in the greased casserole dish and cover with foil. Bake in the preheated oven for 45 minutes.
After 45 minutes, remove the foil, sprinkle the reserved cheese on top, and bake uncovered for another 45 minutes, or until the top is golden brown.
Allow the gratin to rest for 10-15 minutes before serving. This helps the layers set beautifully.

Serve & Enjoy Potato Gratin

When it comes to serving your Potato Gratin, presentation is key! Serve it directly from the casserole dish for a cozy, family-style meal. The layers of creamy potatoes, golden cheese, and crispy edges are visually appealing and inviting.

Pair it with a simple green salad for a bit of freshness, or serve it alongside roasted vegetables or grilled chicken. This dish is versatile and complements a variety of main courses perfectly.

Expert Tips for Potato Gratin

Choose the Right Potatoes: Yukon Gold potatoes are known for their creamy texture, but russet potatoes will work too. Just make sure they are starchy enough to hold their shape during baking.
Thicker Layers: If you prefer a heartier gratin, consider layering in some sautéed mushrooms or spinach for added flavor and texture.
Cheese Variations: Feel free to experiment with other cheese options. Cheddar or mozzarella can add a different twist, though they may alter the dish’s classic taste.
