💡 Tips on How to Cut a Butternut Squash

Cut both ends off your butternut squash and discard.

Stand the butternut squash upright, then take a sharp knife and cut off the peel slicing downward.

Once you’ve removed all of the peel, slice it in half lengthwise.

Using a spoon, scoop out all the seeds and pulp, then discard.  You can wash and roast the seeds if you’d like.

🍴 What to Serve with Butternut Squash

The great thing about butternut squash is there are so many proteins that it will pair nicely with.  These are a few of my favorites:

🔄 Substitutions and Additions

  • If you don’t have fresh thyme, you can use dried thyme.  Another great option is fresh rosemary, which will also give it great flavor. Dried rosemary will also work well.
  • To add a slightly smoky flavor, add in a pinch of smoked paprika.
  • Add in some diced red onion to add more flavor, they will caramelize nicely in the air fryer!
  • Sprinkle a small amount of ground nutmeg, which will compliment the ground cinnamon.

Is Squash Good in the Air Fryer?

Absolutely!  Air frying at a high temperature of 400°F mimics roasting it in the oven, which gives you a nice, slightly caramelized flavor.  It also keeps you from having to turn on your big oven and makes cleanup much easier.

Does Butternut Squash Shrink When Roasted?

Butternut squash will shrink slightly once it’s been roasted, but not by much.

Can You Peel Butternut Squash Before Baking it?

Yes, for this recipe it is actually necessary to remove the peel before air frying it and it makes serving so much easier.  However, you can certainly leave the peel on and roast larger pieces of butternut squash if you’d like, then just remove and discard the peel once it’s cooked.

Can I Eat Butternut Squash on Keto?

Yes, you absolutely can!  While it’s higher in carbs than most greens, it’s still low enough to fit perfectly into your macros.

Recipe Notes

I used a 2 pound butternut squash whole and raw.  Nutritional data took into account the discarded peel, seeds and pulp.  If you decide to use store bought pre-cut butternut squash, you will need closer to 1 1/2 pounds.
