What Do I Need To Make Butternut Squash Casserole?

Squash – A butternut squash has a sweet, nutty flavor and smooth texture. Look for a medium sized squash with a firm skin and without blemishes.

Apples – Use apples that will remain firm when cooked such as Granny Smith or Gala apples. But regarding flavor, any apple will do!

For Sweetness – Use dark brown sugar for this recipe, however light brown sugar will work equally well. Add in or replace brown sugar with maple syrup if desired. Use a sugar substitute such as Swerve brown sugar if you or your guests have this dietary requirement.

For Crunch Pecans give this dish a delicious bit of crunchy texture in every bite. Walnuts work equally well, and can be used in place of pecans.

For Spice – Cinnamon is all the spice needed for this dish, but add in a pinch of nutmeg, pumpkin pie spice or even a small dash of cloves if desired. And if you like more cinnamon flavor, add to your liking!

Recipe Tips

  • Use food safe gloves to peel and chop the squash. Working with butternut squash using bare hands may leave them feeling very dry, and can stain an orange color. Alternately, purchase butternut squash pre-peeled and chopped for added convenience.
  • Prior to prepping the apples, be sure to get all the other ingredients prepped and ready. The less time the apples are exposed to the air, the less they will brown. If you must prep ahead of time, pour a dash of lemon juice over the apples and toss to prevent them from browning too much.
  • Make this casserole a day ahead of time, and simply microwave before serving. The flavors will have had a chance to blend together for an even tastier dish.
