Savory Butternut Squash Gratin

Follow our step-by-step guide on how to make Savory Butternut Squash Gratin.

1. Step 1

   Start by preheating your oven to 350°F (175°C). While it warms up, take a moment to grease a gratin baking dish with a little butter, ensuring it’s ready for the delicious layers to come.

2. Step 2

   In a large skillet, combine 1 tablespoon of butter and 1 tablespoon of olive oil over low heat. Add the chopped onions and fresh sage, then cover the skillet. Let them cook gently, stirring occasionally, until the onions turn a beautiful golden brown, which should take about 25 minutes. Season with salt and freshly ground black pepper to enhance the flavors.

3. Step 3

   Next, prepare to steam the butternut squash. Place a steamer insert into a saucepan and fill it with water just below the bottom of the steamer. Bring the water to a boil, then add the cubed squash. Cover and steam until the squash is tender, which will take about 10 to 20 minutes. Once done, transfer the squash to your prepared gratin dish and toss it with the minced garlic and 3/4 teaspoon of salt. Gently fold in the caramelized onions, mixing everything together with care.

4. Step 4

   Now, let’s add some creaminess! Warm the heavy whipping cream in a saucepan over low heat, then pour it over the squash mixture. Stir gently to ensure everything is well coated and creamy.

5. Step 5

   For that delightful crunch on top, combine the fresh bread crumbs with 1 1/2 tablespoons of melted butter in a bowl. Sprinkle this mixture generously over the squash and onion blend, creating a lovely topping.

6. Step 6

   Finally, place the gratin in your preheated oven and bake until it’s bubbling and the breadcrumbs are golden brown, which should take about 20 to 25 minutes. The aroma will be irresistible!
