Butternut squash gratin is a comforting dish that brings warmth and flavour to any meal. This recipe combines the natural sweetness of butternut squash with a creamy cheese sauce, topped with a golden, crunchy breadcrumb crust. Originating from French cuisine, gratins are known for their rich, satisfying textures and flavours. This version is particularly delightful in autumn and winter, where the earthy tones of the squash are at their peak.

Instructions

Preheat the oven

Preheat your oven to 375°F (190°C). Grease a 9x13-inch (23x33 cm) baking dish.

Pro tip: Ensure your oven is fully preheated for even cooking.

Prepare the squash

Peel and seed the butternut squash. Use a mandoline to slice the squash into 1/4-inch (0.6 cm) thick slices.

Pro tip: Use a sharp knife if you don't have a mandoline.

Layer the squash

Arrange the squash slices in the prepared baking dish, slightly overlapping each slice.

Pro tip: Layering ensures even cooking and a beautiful presentation.

Combine cream and cheese

In a bowl, mix heavy cream, Gruyere, Parmesan, salt, pepper, and thyme. Pour this mixture over the squash slices.

Pro tip: Mix thoroughly to evenly distribute the cheese.

Prepare breadcrumb topping

In a separate bowl, combine panko breadcrumbs with melted butter. Spread this mixture evenly over the squash and cheese.

Pro tip: The butter helps the breadcrumbs brown and crisp.

Bake the gratin

Bake in the preheated oven for 40-45 minutes, or until the top is golden brown and the squash is tender when pierced with a fork.

Pro tip: Cover with foil if the top browns too quickly.

Rest before serving

Allow the gratin to rest for 10 minutes before serving. This helps the layers set and makes serving easier.

Pro tip: Resting enhances the flavours and texture.
