Why You'll Love This Recipe
When the first frost bites, there’s nothing more satisfying than a bubbling, golden‑topped gratin that fills the kitchen with aromatic garlic and buttery cream. This Creamy Garlic Potato Gratin pairs thinly sliced potatoes with winter carrots, parsnips, and Brussels sprouts, creating layers of texture that stay tender yet hold their shape. The subtle hint of nutmeg in the sauce lifts the earthiness, while a crisp breadcrumb crust adds a delightful crunch. Perfect for family dinners or cozy gatherings, it turns simple pantry staples into a memorable centerpiece.
Instructions
Prepare the vegetables
Preheat oven to 190 °C (375 °F). Slice potatoes, carrots, and parsnips thinly (≈3 mm). Halve Brussels sprouts. Rinse and pat dry. This uniform thickness ensures even cooking and a tidy layer in the dish.
Make the garlic‑cream sauce
In a saucepan, melt 2 tbsp butter over medium heat. Add minced garlic, sauté 30 seconds until fragrant. Stir in heavy cream, thyme, nutmeg, salt, and pepper. Simmer gently 4‑5 minutes, allowing flavors to meld and sauce to thicken slightly.
Layer the gratin
Grease a 23 cm (9‑inch) baking dish. Arrange a third of the potatoes, carrots, parsnips, and Brussels sprouts in an overlapping pattern. Pour a third of the cream sauce over the layer, sprinkling a little salt and pepper. Repeat twice, ending with sauce and a generous amount of grated Gruyère on top.
Bake to perfection
Cover the dish with foil and bake 30 minutes. Remove foil and continue baking 15‑20 minutes, until the top is golden brown and the vegetables are fork‑tender. Let stand 10 minutes before serving to set.
Serve and enjoy
Cut generous wedges, garnish with a sprinkle of fresh thyme, and serve hot. Pair with a crisp green salad or roasted chicken for a complete winter dinner.
Expert Tips
Tip #1: Use a hot oven
Starting with a fully preheated oven creates immediate steam, helping the potatoes cook evenly and the top to crisp quickly.
Tip #2: Dry vegetables
After washing, pat the carrots, parsnips, and Brussels sprouts dry. Excess moisture can dilute the sauce and prevent browning.
Tip #3: Rest before cutting
Allow the gratin to rest 10 minutes after baking; this lets the sauce set, making clean slices and a tidy presentation.
