How to Make Rich Potato Gratin

Making rich potato gratin is easier than you might think. With just a few basic steps, you’ll create a deliciously layered dish that everyone will love.

Ingredients

3 tbsp butter
1 small onion, minced
1 garlic clove, grated
1 tsp fresh thyme, chopped or 1/2 tsp dried thyme
3 tbsp flour (use gluten-free if desired)
1 1/2 cups milk or substitute heavy cream
1/2 cup shredded gruyere cheese
1 pinch ground nutmeg (optional)
Salt and black pepper, to taste
4 lb potatoes, sliced thin
1 cup shredded gruyere cheese

Directions

Preheat your oven to 375°F (190°C).
In a large skillet, melt the butter over medium heat. Add the minced onion and sauté until softened, about 5 minutes. Stir in the grated garlic and fresh thyme and cook for an additional minute.
Sprinkle the flour over the onions and mix well, cooking for about 2 minutes to eliminate the raw flour taste.
Gradually pour in the milk (or heavy cream), whisking constantly until the sauce thickens and comes to a simmer. Add the shredded gruyere cheese and a pinch of nutmeg, stirring until fully melted. Season with salt and pepper to taste.
In a greased casserole dish, arrange a layer of thinly sliced potatoes at the bottom. Pour a portion of the cheese sauce over the potatoes. Repeat this process, layering the potatoes and sauce until all ingredients are used, finishing with a layer of cheese sauce on top.
Sprinkle the remaining shredded gruyere cheese over the top layer for that extra cheesy goodness.
Cover the dish with aluminum foil and bake in the preheated oven for 45 minutes. Remove the foil and bake for an additional 15 minutes, or until the top is golden brown and bubbling.
Remove from the oven and let it rest for at least 10 minutes before serving to allow the gratin to set.

Pro Tips for Success with Rich Potato Gratin

Slice Thinly: Use a mandoline or sharp knife to slice your potatoes very thin (about 1/8 inch). This ensures even cooking.
Cheese Substitution: While gruyere is traditionally used, feel free to experiment with other cheeses like cheddar or mozzarella for a different flavor profile.
Use Starchy Potatoes: Opt for starchy potatoes like Russets for a creamier texture, or Yukon Gold for a slightly buttery flavor.
Make Ahead: This dish can be prepared a day in advance; simply assemble it and refrigerate. Bake just before serving.
Cover Properly: Cover your dish during the first part of baking to prevent the top from browning too quickly. Remove the foil to achieve that golden-brown finish.

Flavor Variations for Rich Potato Gratin

Add Vegetables: Try adding sautéed mushrooms or spinach between the layers for a tasty twist and added nutrition.
Spice it Up: Incorporate some crushed red pepper flakes or a dash of paprika for a bit of heat.
Herb Infusion: Experiment with different herbs such as rosemary or oregano for an aromatic touch.
Make It Meaty: Add cooked bacon or ham for a savory, hearty addition.
Nutty Cheese: For a unique flavor, mix in some parmesan cheese along with the gruyere.
