Instructions

Prepare the vegetables

Preheat oven to 375°F (190°C). Thinly slice potatoes and squash (≈1/8‑inch). Pat dry with paper towels to prevent excess moisture during baking.

Pro Tip: Use a mandoline for uniform slices and faster prep.

Make the garlic‑herb cream

In a saucepan, combine heavy cream, minced garlic, thyme, rosemary, salt, and pepper. Simmer gently for 5 minutes, stirring until fragrant; avoid boiling to keep the cream smooth.

Pro Tip: Add a splash of milk if the sauce thickens too quickly.

Layer the gratin

In a greased 9‑x‑13‑inch baking dish, arrange a thin layer of potatoes, then squash, sprinkling a pinch of salt and pepper between layers. Pour half of the cream mixture over the first two layers, then repeat.

Pro Tip: Overlap slices like shingles for even cooking.

Add cheese and bake

Scatter grated Gruyère evenly over the top. Cover with foil and bake for 30 minutes. Remove foil and continue baking 15 minutes until the cheese is golden and the edges bubble.

Pro Tip: For extra crust, broil 2 minutes at the end, watching closely.

Rest and serve

Allow the gratin to rest 10 minutes before slicing. This lets the sauce set, making clean cuts and preserving the creamy interior.

Pro Tip: Garnish with extra thyme for a fresh finish.

Expert Tips

Tip #1: Use a shallow dish

A 9‑x‑13‑inch dish spreads the layers thinly, ensuring the cream penetrates every slice for uniform moisture.

Tip #2: Chill before baking

Assemble the night before, cover, and refrigerate. This saves time on busy evenings and improves flavor melding.

Tip #3: Add a crunch

Mix toasted breadcrumbs with a drizzle of melted butter and sprinkle over the cheese before the final bake for texture.

Storage & Variations

Cool the gratin completely, then refrigerate in an airtight container for up to 3 days. Reheat covered at 350°F (175°C) for 20 minutes. Swap Gruyère for sharp cheddar, or add caramelized onions for a sweeter profile.

Frequently Asked Questions

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

Pat the sliced vegetables dry, use a thickened cream sauce, and bake uncovered for the final 15 minutes. This allows excess moisture to evaporate.

Yes. Replace heavy cream with full‑fat coconut milk and use a dairy‑free cheese such as vegan cheddar. The texture remains creamy, though the flavor shifts slightly.
