- 1 cup Gruyere cheese (shredded) – A nutty, melted cheese that elevates the gratin’s flavor.
- 1 cup milk – Balances the cream for a smooth, pourable consistency.
For the Seasoning
- 2 cloves garlic (minced) – Fresh garlic enhances the overall aroma and taste.
- 1 teaspoon thyme (fresh or dried) – Offers a subtle herbal note that complements the squash beautifully.
- 1 teaspoon salt – Essential for bringing out all the flavors in your Butternut Squash and Gruyere Gratin.
- 1/2 teaspoon black pepper – Adds a gentle kick to balance the dish’s creaminess.
- 1/4 teaspoon nutmeg (freshly grated) – A pinch of nutmeg adds warmth and depth to the flavor profile.
For the Topping

How to Make Butternut Squash and Gruyere Gratin
1. Preheat the oven to 375°F (190°C). This step is crucial for achieving that perfect golden crust on your gratin, so let your oven do its magic while you prep.
2. Combine in a saucepan the heavy cream, milk, minced garlic, thyme, salt, black pepper, and nutmeg. Heat this mixture until it’s just simmering, then remove it from the heat to let those flavors meld beautifully.
3. Layer half of the thinly sliced butternut squash in a baking dish. Pour half of the creamy sauce over these vibrant slices and sprinkle with half of the shredded Gruyere cheese for that irresistible cheesy goodness.
4. Repeat with the remaining butternut squash slices, followed by the rest of the cream mixture and another sprinkle of Gruyere cheese. This layering creates a delightful depth of flavor and texture throughout your dish.
5. Mix in a small bowl the bread crumbs with the remaining Gruyere cheese, then sprinkle this crunchy topping over the gratin. This will give your dish a satisfying crunch when baked.
6. Cover the baking dish with foil and bake for 30 minutes. This helps steam the butternut squash until tender while keeping all those delicious flavors locked in.
7. Uncover and bake for an additional 15 minutes until the top is golden and bubbly. Keep an eye on it—this is where that beautiful color develops!
8. Cool for a few minutes before serving. Letting it sit allows everything to set perfectly for those lovely portions you’ll be serving up.
Optional: Garnish with fresh thyme leaves for an aromatic touch.

Tips for the Best Butternut Squash and Gruyere Gratin
- Slice Thickness: Ensure butternut squash slices are even and thin (about 1/8 inch) for uniform cooking and cream absorption.
- Fresh Ingredients: Use fresh thyme and freshly grated nutmeg to enhance flavors in your Butternut Squash and Gruyere Gratin for a more aromatic dish.
- Avoid Sogginess: Don’t rush the layering process; allow each layer of butternut squash to absorb some cream before adding the next to prevent sogginess.
- Bubbling Cheesy Top: For that golden, bubbly finish, remove the foil halfway through baking. Keep an eye on it to avoid burning.
- Resting Time: Let the gratin cool for a few minutes before serving. This helps set the layers, making it easier to slice and serve.

Butternut Squash and Gruyere Gratin Questions Answered
What type of butternut squash should I use for this gratin?
For this recipe, a medium butternut squash is ideal. Look for one that feels heavy for its size with smooth, firm skin. Avoid any that have soft spots or blemishes, as these can indicate spoilage.
Can I substitute Gruyere cheese with another cheese?
While Gruyere cheese provides a unique nutty flavor, you can substitute it with a similar cheese like Emmental or Fontina for a comparable melting quality. If you’re looking for a more budget-friendly option, Swiss cheese can also work well, although the flavor will be slightly different.
How should I store leftovers of the butternut squash and Gruyere gratin?
After letting your gratin cool completely, transfer it to an airtight container. It can be stored in the refrigerator for up to 3-4 days. When you’re ready to enjoy it again, simply reheat in the oven at 350°F (175°C) until warmed through.
Can I freeze the gratin before baking?
Absolutely! To freeze, assemble the gratin as directed but do not bake it. Cover tightly with plastic wrap and then aluminum foil to prevent freezer burn. It can be frozen for up to 2-3 months. When ready to bake, thaw in the refrigerator overnight and then cook as per the original instructions.
What if my gratin isn’t bubbling or browning after baking?
If your gratin hasn’t reached that golden-brown perfection after 45 minutes, it might need a little more time in the oven. Try covering it with foil again if it’s browning too quickly while allowing it to bake longer until bubbly and golden on top—usually an additional 5–10 minutes will do the trick!
