Instructions

Prepare the vegetables

Preheat oven to 190 °C (375 °F). Peel and slice potatoes, carrots, and parsnips to a uniform ¼‑inch thickness. Thinly slice onion and mince garlic. Set aside in separate bowls.

Pro Tip: Soak potato slices in cold water for 5 minutes to remove excess starch and keep them from browning.

Make the cream sauce

In a saucepan over medium heat, combine heavy cream, minced garlic, half the rosemary, salt, and pepper. Bring to a gentle simmer, stirring occasionally, then remove from heat.

Pro Tip: Do not boil; a simmer preserves the cream’s richness without curdling.

Layer the gratin

Grease a 23 × 33 cm (9‑by‑13‑inch) baking dish. Start with a thin layer of potatoes, then onions, carrots, and parsnips. Sprinkle salt, pepper, and a pinch of rosemary. Pour a third of the cream sauce over the top. Repeat layers twice, finishing with a final cream pour.

Pro Tip: Keep layers even; this ensures uniform cooking and a tidy appearance.

Add cheese and bake

Evenly distribute grated Gruyère over the top, then sprinkle the remaining rosemary. Cover dish with foil and bake for 30 minutes. Remove foil and continue baking 15‑20 minutes, or until the cheese is golden and the vegetables are fork‑tender.

Pro Tip: If the cheese browns too quickly, loosely tent foil over the top.

Rest and serve

Allow the gratin to rest for 10 minutes before cutting. This lets the sauce set and makes serving easier. Garnish with a drizzle of olive oil or a sprinkle of fresh rosemary if desired.

Pro Tip: Leftovers taste even better chilled, as flavors meld overnight.

Expert Tips

Tip #1: Uniform Slicing

Use a mandoline or a sharp chef’s knife to slice all vegetables the same thickness; this guarantees even cooking and a tidy appearance.

Tip #2: Cream Balance

If you prefer a lighter dish, replace half the heavy cream with low‑fat milk; the cheese will still provide richness.

Tip #3: Fresh Herbs

Add a handful of fresh thyme leaves alongside rosemary for an extra layer of piney aroma that complements winter vegetables.

Storage & Variations

Refrigerate leftovers in an airtight container for up to 3 days; reheat covered to retain moisture. For a vegan version, swap cream for coconut milk and use nutritional yeast instead of cheese. Add sliced leeks or fennel for a subtle anise note, or sprinkle toasted pine nuts just before serving for crunch.

Frequently Asked Questions

Yes. Sweet potatoes add extra sweetness and a vibrant color. Use the same quantity, but keep the slices thin to ensure they cook through in the same time as the other vegetables.

Cover the dish with foil for the first 30 minutes of baking. Remove the foil only for the final 15‑20 minutes to let the cheese brown without scorching.

Assemble the gratin up to the cheese layer, cover tightly, and refrigerate up to 24 hours. When ready, bake as directed, adding an extra 5‑10 minutes if baking from cold.
