How to Make Parmesan-Butternut Squash Gratin
Preheat your oven to 375 °F (190 °C). This temperature ensures even cooking and a beautifully golden topping on your gratin.
Peel and slice the butternut squash into 1/4-inch thick pieces for even cooking. This consistency will help the squash become tender and creamy as it bakes.
Melt the butter in a skillet over medium heat, then add the finely chopped garlic. Sauté for about 2 minutes until the garlic is fragrant but not browned.
Layer half of the sliced butternut squash in a greased baking dish. Sprinkle with salt and pepper to enhance the natural sweetness of the squash.
Pour the garlic butter evenly over the squash layer, then sprinkle half of the grated Parmesan cheese on top for that delightful cheesy flavor.
Repeat the layering by adding the remaining squash slices and seasoning again with salt and pepper. Top it off with the remaining garlic butter and Parmesan cheese.
Sprinkle the panko breadcrumbs on the very top to add a crunchy texture that contrasts beautifully with the creamy interior.
Bake in the preheated oven for approximately 1 hour and 15 minutes, or until the squash is tender when pierced with a fork and the topping is golden brown.
Garnish with freshly chopped parsley before serving. This adds a lovely touch of color and brightness to the dish.
Optional: For an extra layer of flavor, try adding a pinch of nutmeg to the squash layers!

Parmesan-Butternut Squash Gratin Recipe FAQs
How do I choose the perfect butternut squash?
Absolutely! Look for squashes that feel heavy for their size with a smooth, firm skin. Avoid any with dark spots or soft spots indicating ripeness issues. A good butternut squash should have a creamy beige color and a sturdy stem for the best flavor!
How should I store leftovers from the gratin?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350 °F until warmed through, which helps to maintain the lovely texture of the gratin without making it soggy.
Can I freeze Parmesan-Butternut Squash Gratin?
Yes, this dish freezes wonderfully! Wrap the cooled gratin tightly in plastic wrap, then foil, to prevent freezer burn. It will keep well for up to 2 months.

What if my gratin topping burns before the squash is tender?
Very! If you notice that the topping is browning too quickly, simply cover the dish with aluminum foil. This allows the squash to continue cooking through without over-browning the breadcrumbs. Just remember to remove the foil during the last 10-15 minutes of baking for that golden finish!
Is this recipe suitable for people with allergies?
Of course! This gratin is vegetarian-friendly and can be adjusted for common allergens. You can substitute gluten-free breadcrumbs if needed, and using olive oil instead of butter or margarine is a great dairy-free option.
