If you’re missing an ingredient or looking to switch things up, consider these substitutions:

• Yukon Gold Potatoes: Russet or red potatoes can be used, but may alter the texture slightly.
• Nutmeg: If you don’t have nutmeg, a pinch of cinnamon can add warmth.

How to Make Potatoes Au Gratin

Follow these steps for a flawless au gratin recipe:

1. Preheat the Oven: Set the oven rack to the middle position and heat to 400ºF (200ºC).
2. Make the Cream Sauce: In a large skillet over medium-low heat, melt the butter. Add garlic and onions, and sauté until fragrant, about 2 minutes. Stir in the flour, whisking to combine, and cook for 2 minutes. Gradually whisk in milk and cook until thickened, about 2 to 3 minutes. Turn off the heat and whisk in salt, pepper, and nutmeg.
3. Add the Cheeses: Stir in ½ cup of both gruyere and sharp cheddar cheese until well combined.
4. Assemble the Casserole: Grease an 8-inch square casserole dish. Layer half of the potatoes in overlapping rows. Spread half of the cheese sauce over the potatoes, followed by a sprinkle of ¼ cup each of gruyere and cheddar. Repeat with the remaining potatoes and sauce, finishing with the remaining cheese.
5. Bake: Cover with foil and place on a baking sheet. Bake for 30 minutes, then remove the foil and continue baking until the potatoes are tender and the cheese is golden and bubbly, about 20 to 25 minutes.
6. To Serve: Allow the casserole to cool on a wire rack for 10 to 15 minutes. Garnish with chopped chives before serving.
