What Kind of Potatoes Work Best for Crispy Parmesan and Gruyere Potato Gratin?

You’ll want to use starchy potatoes like Russets or Yukon Golds. Russets offer a light, fluffy texture that soaks up the cream mixture well, while Yukon Golds add a natural buttery flavor and hold their shape nicely. Avoid waxy varieties like red potatoes, as they won’t give you the same tender bite.

How To Make the Crispy Parmesan and Gruyere Potato Gratin

This isn’t just about throwing potatoes in a dish; it’s about layering flavor and baking to golden perfection.

Step 1: Prep the Ingredients

Peel the potatoes and slice them thinly using a mandoline for uniform slices. Grate both cheeses and mince the garlic. Preheat your oven to 375°F.

Step 2: Infuse the Cream

In a saucepan over medium heat, combine the heavy cream, minced garlic, salt, pepper, and thyme. Bring to a gentle simmer, then remove from heat.

Step 3: Layer the Gratin

Butter a baking dish. Add a single layer of potatoes, followed by a spoonful of the garlic cream and a mix of Gruyere and Parmesan. Repeat until all ingredients are used, finishing with a generous sprinkle of Parmesan on top.

Step 4: Bake Until Golden

Cover with foil and bake for 45 minutes. Remove the foil and bake an additional 20-25 minutes until the top is golden brown and crispy.

Step 5: Rest Before Serving

Let the gratin sit for 10 minutes before slicing. This allows it to set and makes serving easier.
