Serving Suggestions for Butternut Squash Crostini

This dish is perfect to serve at Thanksgiving, Friendsgiving, or any fall celebration. I love it for potlucks, game nights, or casual gatherings with friends in autumn. Pair this dish with a crisp white wine or a light-bodied red for the best flavor combination.

Variations

  • Cheese: Try goat cheese, Gruyère, or a sprinkle of blue cheese.
  • Spices: Add a pinch of cinnamon or nutmeg to the squash.
  • Herbs: Use rosemary or thyme instead of, or in addition to, the sage.

Prep Ahead and Storage

  • Prep Ahead: Roast the squash and caramelize the onions a day in advance. Store separately in airtight containers in the refrigerator.
  • Storage: These crostini are best enjoyed fresh, but leftovers can be stored in an airtight container in the refrigerator for up to 2 days. While you can freeze the crostini, the texture may change slightly upon thawing. For best results, enjoy them fresh!
