Ingredients for Sage Butternut Squash Gratin
Here’s what you’ll need to make this delicious Sage Butternut Squash Gratin:
1 pound butternut squash – Choose fresh squash, as it provides the best quality and flavor for the dish. Peel and slice it to ensure even cooking.
4 tablespoons unsalted butter – Butter adds richness and depth to the sauce, enhancing the overall flavor profile.
4 tablespoons all-purpose flour – This will thicken the sauce, giving it a creamy and luxurious texture that clings beautifully to the squash.
2 cups milk – Whole milk works best for achieving creaminess, but you can use a non-dairy alternative if necessary.
1 cup fontina cheese – A semi-soft cheese that melts perfectly, adding that indulgent creaminess to your gratin.
2 cups parmesan cheese – Freshly grated parmesan is essential for an authentic taste and contributes to the dish’s savory depth.
1 tablespoon fresh sage – This aromatic herb perfectly complements the sweetness of the squash, adding a fragrant touch.
¼ teaspoon freshly grated nutmeg – A pinch enhances the flavors of the gratin, bringing warmth and earthiness.
¼ teaspoon ground black pepper – A little pepper brings a subtle kick that balances the dish’s creaminess.
½ cup panko breadcrumbs – These will create a crispy topping, adding texture to every mouthful.
How to Make Sage Butternut Squash Gratin
Follow these simple steps to prepare this delicious Sage Butternut Squash Gratin:
Step 1: Preheat and Prepare Your Dish
Preheat your oven to 375°F (190°C). Grease an 8 x 8-inch baking dish or individual mini cast iron skillets with butter for easy serving.
Step 2: Create the Butter and Flour Base
In a medium saucepan over medium heat, melt the 4 tablespoons of butter. Once melted, whisk in the flour, stirring continuously for about 2 minutes until it forms a smooth paste.
Step 3: Make the Creamy Sauce
Gradually pour in the 2 cups of milk, whisking constantly until the mixture thickens. Add in the fontina cheese and half of the parmesan cheese, stirring until melted and completely smooth. Mix in the fresh sage, nutmeg, and black pepper. Don’t forget to sneak a taste and adjust seasoning as needed!
Step 4: Layer the Gratin
In your prepared baking dish, layer one-third of the sliced butternut squash in a single layer. Pour one-third of the cheesy sauce over the layer. Repeat this process, finishing with a final layer of sauce on top of the last squash layer.
Step 5: Add the Topping
Mix the remaining parmesan cheese with the panko breadcrumbs, then sprinkle this golden mixture evenly over the top of the gratin. If you’re feeling adventurous, toss in some more fresh sage for extra flavor!
Step 6: Bake to Perfection
Carefully place your baking dish on a baking sheet to catch any spills, cover it with foil, and bake for 30 minutes. After this, remove the foil and continue baking until the top turns a beautiful golden brown and the squash becomes tender.
Once out of the oven, allow your gratin to sit for about 5 minutes before serving. It’s the perfect time for your mouth to water in anticipation of the creamy goodness that awaits you! Serve alongside roasted meats or a simple green salad for a delightful dinner that will leave your family asking for seconds. Enjoy your culinary creation!
