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!

  • Denise O.: Oh my! I had two small squash, so decided to try this tonight with one of them. I had no parm cheese, but had a little bit of feta, so I went for it. I hope it turns out. Smells great!! I thought the hardest part was trying to layer the squash slices… Will definitely NOT look like your pic, but I’m sure will taste wonderful. April 11, 2016 at 5:03pm Reply
