An Easy, Versatile Side Dish with the Flavors of Fall

I don’t know what it is about butternut squash that makes it such a perfect fall side dish. But I do know that when the weather cools down, I love to enjoy my favorite winter squash recipes!

It could be that the sweetness pairs deliciously with fall spices, like cinnamon and nutmeg. Or maybe it’s because no Thanksgiving or Christmas spread is ever without a platter of perfectly roasted squash around here!

This air fryer butternut squash is one of my favorite things to roast up and customize. Of course, it helps that butternut squash is naturally gluten-free, healthy, and easily “glows up” into the best versatile side dish.

And during the festive season, I’m always planning how to free up valuable oven space. As it turns out, the air fryer may just be the best way to cook butternut squash. It’s certainly the quickest! This squash recipe is tender, crisp at the edges, and ready for garnishing in 20 minutes or less.

Is Butternut Squash Good for You?

Yes! Butternut squash is low in calories while being extra high in fiber, vitamins, minerals, and antioxidants. It’s a winter squash loaded with disease-fighting benefits, that also happens to taste delicious!

Butternut squash is a simple side dish with boundless potential! Below is what you’ll need for roasting squash in the air fryer, with the full amounts further down in the recipe card:

  • Olive Oil: Use a good quality extra virgin olive oil to coat your squash cubes. 
  • Salt & Pepper

How to Make Air Fryer Butternut Squash

Alright, let’s roast some squash! First, you’ll need to wash, peel, and chop your butternut squash into small pieces. I like to do this while the air fryer preheats. 

Once the fryer is heated to 400ºF and the squash is prepped, here’s how to cook squash in the air fryer: 

Prep the Squash: Combine the butternut squash cubes in a bowl along with a pinch of salt and pepper, plus any other seasonings you’d like. Add olive oil and toss to coat.

Cook: Give the basket of your preheated air fryer a spritz with oil cooking spray. Avoid non-stick aerosol sprays like PAM (see the tips below). Next, you’ll add the seasoned squash into the basket and cook for 16 to 20 minutes. Give the basket a shake about halfway through.

Serve: If you’re adding nuts to this recipe, add them towards the end of the cooking time. The butternut squash is ready to serve when the insides are fork tender and the outsides are crispy and golden.

Serve your butternut squash hot from the air fryer, garnished with any herbs, cheese, or add-ins to your family’s taste.

Tips and Tricks

Here are some additional tips to keep in mind when cooking butternut squash in the air fryer:

  • Never Use Non-Stick Sprays: Aerosol cooking sprays like PAM will damage the non-stick coating on your air fryer basket. In fact, these non-stick sprays shouldn’t be used on any non-stick surfaces! When air frying, be sure to use a cooking oil spray instead (such as olive oil or vegetable oil in a spray bottle). 
  • Keep An Eye While Cooking: Not all air fryers are the same. The exact cooking times will vary depending on your model (and also the size of your squash cubes). Begin checking your butternut squash starting around the 15-minute mark to ensure it doesn’t overcook.
  • Oven-Roasted Butternut Squash: If you’d prefer to roast your squash the old-fashioned way in an oven, try my Easy Roasted Butternut Squash recipe.

Storing and Reheating

Store the cooled butternut squash airtight in the fridge for up to 4-5 days. Reheat leftover squash by returning it to the air fryer, or heating it in the oven at 350ºF until warmed through. Alternatively, you can warm it in the microwave in a pinch.

The cold butternut squash cubes are great to throw over a fresh green salad. Or, turn your leftover air fryer butternut squash into savory Butternut Squash Soup or Butternut Squash Macaroni and Cheese!

Can I Freeze Air Fryer Butternut Squash?

You can absolutely freeze your air fryer butternut squash for longer-term storage. Store the squash cubes in a freezer-safe airtight container, or resealable freezer bag with the air pressed out. Frozen butternut squash can be thawed in the fridge, or reheated straight from frozen.

What Air Fryer Should I Buy?

I may not have a lot of extra counter space, but the Cosori 5.8 Qt air fryer has earned a spot on my countertop. I use it all the time for roasting veggies like this, making appetizers like pizza rolls, cooking a whole chicken, or just heating up frozen fries.
