I’ve finally got my husband to love butternut squash – with this recipe! It really is one of the best butternut squash recipes I’ve tried and I know I’ll be making this one again and again. This one is even worthy of making it to the holiday menu.

This Parmesan Butternut Squash Gratin is so simple to prepare once you get past the peeling and cutting. If you aren’t familiar with the how to of peeling, seeding and cutting the squash here is a quick video that shows how here.

Once you try this delicious recipe you’ll be hooked! The crisp Panko bread crumbs and salty parmesan pairs so well with the soft and buttery squash, and the herbs and garlic just give it that extra boost of flavor.

Even my picky four year old loved it! I thought it would be years before I could get my kids to like squash. No one could resist this! Trust me, it will disappear in no time!
