how to serve Dauphinoise Gratin
Serve Dauphinoise Gratin hot, straight from the oven. It is a delightful side dish that goes well with roasted meats, grilled chicken, or a fresh salad. You can sprinkle some fresh herbs like thyme or parsley on top for added flavor and a touch of color.
how to store Dauphinoise Gratin
Let the gratin cool completely before storing it. Place it in an airtight container and store it in the refrigerator for up to 3 days. To reheat, cover it with foil and bake in a preheated oven at 350F (175C) until heated through.
tips to make Dauphinoise Gratin
- Use a mandoline slicer for evenly sliced potatoes; it will ensure they cook uniformly.
- For extra depth of flavor, try adding a pinch of nutmeg or thyme to the cream mixture.
- If you can’t find Gruyere cheese, any good melting cheese like Comté or even cheddar will work well.
variation
You can add cooked bacon or ham between the layers for a heartier version. Another variation is to sprinkle some cooked onions or leeks for added sweetness and taste.
