How to make air fryer baked butternut squash fries
This is an overview of the recipe. Full recipe Instructions can be found in the printable recipe card below.
Wash and dry the whole winter squash, cut the squash into fries more details below. Toss in oil and old bay seasoning.

Spray air fryer basket, then air fry to crispy perfection.

How to roast frozen butternut squash in the air fryer.
To get crispy frozen butternut squash in the air fryer, follow the steps below.
- Do not defrost: You need to cook straight from frozen. Thawing will make the vegetable soggy and would not be crispy.
- Preheat the air fryer: For frozen butternut squash preheating is key because it helps it hit the ground running if I may say so. It helps the moisture start evaporating off the veggies as soon as it hits the air fryer basket.
- Don’t forget to spray the air fryer basket before air frying and spray ok some oil on the veggie half way through the cooking time. By this time the heat in the air fryer has thawed the squash and it’s ready for some oil. I prefer to do it this way since the oil will slide off the frozen squash as it cooks if I had tossed in oil before baking.

How to cut butternut squash into fries
You might want to soften this winter squash in the microwave for 1-2 mins to soften it a bit but I’d be honest with you, I rarely do so.
Next cut off the top where the stem is, cut it down the middle to reveal the seeds. using a vegetable peeler or knife then scoop out the seeds, cut into ¼ inch slices and then into ¼ inch sticks

Alternatively cut the squash in two at the neck, scoop out the seeds with a spoon, Peel the skin.
Next cut into round slices about ½ an inch think, cut the slices into ¼ inch sticks to get fries. If you want cubes, you would need to cut the round slices up to 1 inch thick before cutting the round slices into 9 cubes.
You can add some fun to the veggies by using a crinkle cutter or crinkle knife to make butternut squash crinkle cut fries.
Seasoning suggestions
I used old bay seasoning in this recipe however there are a variety of seasoning blends to use as butternut squash fries seasoning options. Some are listed below
- Cajun
- Garlic salt
- Garlic and herbs like oregano or Italian seasoning.
- Taco seasoning
- Suya spice
- Piri Piri seasoning
- Garam masala

Why is my food not crispy in the air fryer?
There are various reasons why food may not get crispy on the air fryer which include over crowding the air fryer basket or even not cooking long enough.
That being said not all foods get very crispy in the air fryer because they simply can’t. For instance homemade sweet potato fries won’t get as crispy as store bought frozen fries.
However you can get juicy chicken drumsticks or wings with crispy skin in the air fryer.
Butternut squash fries dipping sauce
What would you dip your fries in? We love to dip these in ketchup, fry sauce or barbecue sauce.

Tips for success
- Try to cut the fries to be as close to the same size as possible to ensure even cooking.
- Do not overcrowd the basket. Remember to shake basket at 5 minute intervals.
- I preheated my Cosori air fryer to major this recipe, however you can also make it in a non preheated air fryer. It would only take a couple of minutes extra for your first batch but subsequent batches will cook faster.
- If using the oven style air fryer, bake in the middle rack and allow extra time as the basket style air fryers tend to cook faster than oven style air fryers.
