2 medium carrots, diced Adds sweetness and color.
2 parsnips, diced Provides earthy depth.
200 g Brussels sprouts, halved Gives a slight bitterness that balances richness.
3 garlic cloves, minced Essential for the aromatic base.
1 cup heavy cream For a silky, rich sauce; substitute half‑and‑half if preferred.
150 g Gruyère, grated Adds a nutty, golden crust.
1 tsp fresh thyme, leaves only Or ½ tsp dried.
1 tsp fresh rosemary, finely chopped Optional for extra piney aroma.
Salt and freshly ground black pepper Season to taste at each layer.

Instructions

1

Prepare the vegetables

Preheat oven to 190 °C (375 °F). Toss carrots, parsnips, and Brussels sprouts with 1 tbsp olive oil, salt, and pepper. Spread on a baking sheet and roast 15 minutes until just tender.

Pro Tip: Roasting first prevents soggy vegetables in the final gratin.
2

Make the garlic‑herb cream

In a saucepan, melt 2 tbsp butter over medium heat. Add minced garlic, thyme, and rosemary; sauté 30 seconds. Stir in heavy cream, bring to a gentle simmer, then season with salt and pepper. Remove from heat.

Pro Tip: Do not boil the cream; a low simmer preserves its silky texture.
3

Layer the gratin

In a greased 23 × 33 cm (9 × 13 in) baking dish, arrange a third of the sliced potatoes, overlapping slightly. Sprinkle half the roasted vegetables, then drizzle with one‑third of the cream sauce. Repeat layers twice, finishing with potatoes and the remaining sauce.

Pro Tip: Season each potato layer; it builds depth throughout the dish.
4

Add cheese and bake

Sprinkle grated Gruyère evenly over the top. Cover the dish with foil and bake 30 minutes. Remove foil and continue baking 15 minutes, or until the cheese is golden and the potatoes are fork‑tender.

Pro Tip: If the cheese browns too quickly, tent with foil again.
5

Rest and serve

Let the gratin rest 10 minutes before cutting. This allows the sauce to set, making slices clean and preventing a runny plate. Garnish with a sprinkle of fresh thyme if desired.

Pro Tip: Resting also intensifies the herb flavor.

Expert Tips

Tip #1: Slice uniformly

Use a mandoline or a sharp chef’s knife to get 3‑mm slices; even layers cook evenly and look professional.

Tip #2: Boost flavor

Add a pinch of nutmeg to the cream sauce; it subtly enhances the earthy potatoes without overpowering.

Tip #3: Make ahead

Assemble the gratin a day before, refrigerate uncovered. Bake when ready; the flavors meld even more.

Storage & Variations

Refrigerate leftovers in an airtight container for up to 3 days; reheat covered at 180 °C (350 °F) until hot. For a lighter version, replace half the cream with low‑fat milk. Swap vegetables with winter squash or add sautéed mushrooms for extra earthiness.

Frequently Asked Questions

Yes. Sharp cheddar, Fontina, or a blend of mozzarella and Parmesan work well. Choose a cheese that melts smoothly and adds the flavor profile you prefer.

Pat the sliced potatoes dry with paper towels before layering, and avoid over‑saucing. The pre‑roasted vegetables also absorb excess moisture.

Absolutely. The recipe is naturally gluten‑free; just ensure any added flour for thickening (if used) is a gluten‑free variety.
