My family loves to enjoy this Butternut Squash Galette as a light lunch. It has a sweet and spicy flavor that is enhanced more with cayenne pepper and brown sugar stirred in to caramelize the onions. This recipe is one of my family’s favorite butternut squash recipes!

Butternut Squash Recipes For The Win

My entire family loves butternut squash. It is a hearty winter squash that will keep throughout the winter (hence the name) allowing it to be enjoyed all winter long. Often times squash recipes are thought of as a side dish, and we love to eat it mashed with a little butter and maple syrup, similar to this Acorn Roasted Squash recipe.

However, we love butternut squash so much that we enjoy it in enchiladas, lasagna, macaroni and cheese, and more! Check the end of this post for links to many of our very favorite butternut squash recipes!

What You Need To Make Butternut Squash Galette

Butternut Squash can be difficult for some to peel and cut. It’s a very hard squash and you will need a good sturdy sharp knife if you are cutting it yourself. If you are cutting your own, a small butternut squash should give you the 4 cups needed for this recipe. The other o

ption is to  purchase it in the store already cut. 

The pie crust recipe on my Rhubarb Custard Pie post is a good one to use if you are making your own crust. This will give you enough crust for 2- 8″ rounds. I like to make this recipe and store the 2nd pie crust in the fridge for another use.

Fresh sage leaves

Vidalia onion

Havarti Cheese is a semi-hard cheese with a sweet and mild flavor. It is excellent in this tart.

Tips and Substitutions

  • Be sure the onions are cooked low and slow to prevent burning.
  • For quick and easy meal prep, purchase pre-made pie crust and pre-cut butternut squash
  • Place the pie crust on parchment paper lined baking sheet before forming the galette
  • Substitute 1 teaspoon dried rubbed sage for the fresh sage leaves
  • Substitute 1/2 cup blue cheese crumbles or feta for the Havarti cheese. These cheese will give the tart a different flavor profile to the tart, but it is still absolutely delicious!

    This looks amazing, however I’m still afraid to use pumpkin… It’s not a common vegetable here in Holland, so I’m not used to cooking with it. In fact: I have never cooked anything with pumpkin! The muffins for TWD will be the first thing!
