How to Make Sage Butternut Squash Gratin
Step 1: Prepare the Squash
Start by peeling and slicing your butternut squash into thin rounds. This step is crucial because thinner slices cook more evenly, allowing the flavors to blend beautifully. Set aside while you prepare the sauce.
Step 2: Make the Sauce
In a medium saucepan over medium heat, melt the butter until bubbly. Whisk in the flour to create a roux—this will help thicken your sauce. Slowly pour in the milk while whisking constantly. Cook until the mixture thickens slightly, about 5 minutes. Stir in half of the parmesan cheese along with sage, nutmeg, and black pepper. This step adds depth to your sauce!
Step 3: Layer the Dish
Preheat your oven to 375°F (190°C). In a greased baking dish, layer half of the butternut squash slices at the bottom. Pour half of your creamy sauce over them. Repeat with another layer of squash and sauce on top.
Step 4: Top with Cheese and Breadcrumbs
Sprinkle the remaining parmesan cheese over your gratin, then top with panko breadcrumbs for that delightful crunch! This gives an amazing contrast to the creamy layers below.
Step 5: Bake
Cover your baking dish with foil and bake for 30 minutes. Remove the foil and bake for an additional 10 minutes or until golden brown and bubbling. Allow it to cool slightly before serving—this helps everything set beautifully!
Enjoy every bite of this comforting Sage Butternut Squash Gratin; it’s sure to become one of your favorites!
Pro Tips for Making Sage Butternut Squash Gratin
Making the perfect Sage Butternut Squash Gratin is all about attention to detail and a few helpful tricks!
Choose ripe squash: Selecting a ripe butternut squash ensures a naturally sweet flavor, making your gratin even more delicious.
Pre-cook the squash: Lightly steaming or microwaving the sliced squash before layering helps reduce cooking time and ensures it’s tender by the end of baking.
Use room temperature milk: Incorporating room temperature milk into your sauce prevents clumping and promotes a smooth, creamy texture throughout the gratin.
Experiment with cheeses: While fontina and parmesan are classic choices, mixing in other cheeses like gouda or mozzarella can add unique flavors and creaminess.
Don’t skip the breadcrumbs: The crunchy panko topping contrasts beautifully with the creamy layers below, providing an irresistible texture that elevates the entire dish.
How to Serve Sage Butternut Squash Gratin
Serving your Sage Butternut Squash Gratin is as much about presentation as it is about flavor. With a few thoughtful touches, you can create an inviting dining experience!

- Grated cheese: Sprinkling some extra grated parmesan on top just before serving adds a touch of elegance and reinforces that cheesy goodness.
Side Dishes
Garlic roasted green beans: Tossed with olive oil and minced garlic, these crisp green beans provide a fresh contrast to the rich gratin.
Mixed greens salad: A light salad with arugula, cherry tomatoes, and a lemon vinaigrette offers brightness that balances out the creaminess of the gratin.
