Getting into the rhythm of making butternut squash gratin is straightforward and rewarding. Begin with prepping your ingredients, followed by simple steps to sauté aromatics and prepare layers of squash.

Ingredients

What you’ll need

To whip up this delightful gratin, gather the following ingredients:

1 medium butternut squash, peeled and sliced
1 cup heavy cream
2 shallots, finely chopped
2 cloves garlic, minced
2 teaspoons fresh sage, chopped
Salt and pepper to taste
Grated cheese for topping (optional)

Optionally, feel free to substitute the heavy cream with half-and-half for a lighter version or use nut-based cream for a dairy-free option!

Directions

Step-by-step instructions

Begin by preheating your oven to 375°F (190°C).
In a skillet, heat a drizzle of oil over medium heat. Sauté the shallots and garlic until they soften, about 2-3 minutes.
Stir in the fresh sage and let it cook for another minute to release its aromatic flavor.
Pour in the heavy cream and allow it to come to a gentle simmer. Once simmering, remove from heat.
Grease a baking dish and layer the butternut squash slices, seasoning each layer with salt and pepper.
Evenly pour the creamy mixture over the squash to ensure every slice is coated.
If you’re a cheese lover, sprinkle a generous amount of grated cheese on top for that golden crust.
Bake for 35-40 minutes, or until the squash becomes tender and the top turns a beautiful golden brown.
Once done, let it sit for a few minutes before serving to let the flavors settle.

How to serve Butternut Squash Gratin

Best ways to enjoy it

Elevate your butternut squash gratin experience by serving it alongside roasted meats or a crisp green salad for balance. It’s also wonderful as a stand-alone dish during a vegetarian dinner. A sprinkle of fresh herbs or a drizzle of balsamic reduction can add a touch of elegance when plating.

How to store

Storage and reheating tips

To keep your leftover butternut squash gratin fresh, allow it to cool completely, then store in an airtight container in the fridge for up to 3-4 days. When you’re ready to enjoy it again, reheat in a preheated oven at 350°F (175°C) until warmed through. If you have a larger batch, you can also freeze it; simply wrap it well in freezer-safe packaging to preserve its deliciousness for up to three months.

Tips to make

Helpful cooking tips

For an even creamier texture, consider adding a layer of ricotta cheese between the squash slices. Another trick is to sprinkle some nutmeg into the cream sauce—its warmth pairs beautifully with the butternut squash. Don’t skimp on the layer of cheese on top; this creates a delectable crust that makes each serving irresistible!

Variations

Creative twists

Feel free to customize your butternut squash gratin with different herbs or spices. Thyme or rosemary can replace sage, while adding a hint of cayenne can introduce a subtle kick. For a unique flavor profile, try incorporating roasted garlic or even a touch of maple syrup for sweetness.
