Parmesan Butternut Squash Gratin

Jump to Recipe Print Recipe
Pinterest image for butternut squash au gratin

I'm a known Trader Joe's finatic. I especially love their seasonal items, such as the Butternut Squash Gratin. But because these items are only in stores for a few weeks, if there's a meal I love I like to reinvent it in my own recipe. That's how this recipe for butternut Squash Gratin came to be.

Rings of butternut squash are baked topped with a parmesan panko seasoned bread crumb. This recipe is a favorite of mine for a reason!

What is a Gratin?

The definition of a gratin is very broad. Gratin is a culinary technique for any dish that is topped with a browned crust. This can range from breadcrumbs, to cheese or even butter. Gratins are typically baked in a shallow dish and are usually a vegetable side dish. Some gratins have a creamy sauce underneath the breading and other, like this recipe, simply have the vegetable.

Almost any vegetable can be made into a gratin. Some of my favorites are potatoes au gratin, onions au gratin and greens au gratin.

What is a butternut Squash

Butternut Squash is a common form of winter squash. It is known for its pale orange exterior and bright orange interior. It tastes similar to pumpkin but with a distinct nutty flavor. This squash is common and can be found at most grocery stores year round, however it is in season during the fall months.

Can't find butternut squash? Other winter squash varieties such as acorn, delicata, or kabocha can be used as substitutes. Many store will also have pre cut butternut squash available. For ease of use, feel free to use cubed or ribbon cut butternut squash.

How to prep butternut squash gratin

To begin, slice the butternut squash in half width wise (or in elementary school terms hamburger) right above the bulb. Slice off the stem and bottom of bulb end. Scoop out the seeds. Using a vegetable peeler, remove the skin. Then slice the squash into ½ inch rings. Place in a large baking dish and season with salt and pepper generously

Ingredients Needed

  • 2 ½ Pounds Butternut Squash 
  • Salt
  • Pepper
  • ¼ Cup Butter
  • 2 Cloves Garlic Sliced
  • ¼ Cup Panko Bread Crumbs
  • ⅓ Cup Parmesan Cheese Grated
  • Parsley optional

Equipment Needed

  • Chef's Knife
  • Cutting Board
  • Mixing Bowl

Storage

Butternut Squash Storage: Uncut butternut squash can be kept out at room temperature for up to 2 months in a cool, dry place. Discard the squash if it begins to become discolored, soft or has grey or slimy seeds. Once cut, butternut squash should be stored in a refrigerator and used within a few days.

Leftovers Storage: Cover leftovers with aluminum foil or place into an airtight container. Store in the fridge for up to 4 days. Squash can be reheated by using a microwave oven. I do not suggest storing leftovers in the freezer for this recipe as the panko breading did not fare well when I tested it.

Other side dishes you'll love

I love making side dishes and let's face it they are often our favorite parts of the meal. Some of my other favorites include Green Beans Amandine, Apricot Glazed Carrots, Collard Greens with Bacon, Candied Yams and Twice Baked Potatoes.
