Searching for a simple side dish that is really easy to make? Air fryer frozen butternut squash is a great option!
Similar to fresh butternut squash in the air fryer, these tasty little seasoned cubes are versatile and ready for serving alongside a nice dinner!

Recipe Tips
Before you make frozen butternut squash in the air fryer, read through these recipe tips so that you know what to expect!
- Your cooking time might vary based on your air fryer and the size of the butternut squash cubes. Ours were quite small (about a 1/4 inch thick) so if yours are thicker, your cooking time will likely increase a little bit.
- You don’t need to thaw the butternut squash cubes first. You can add them to the air fryer from frozen.
- We used simple seasonings (salt, pepper, garlic powder) for our butternut squash cubes – but you can change up the spices to suit your tastes!
- Since these squash cubes are from frozen, do not expect them to get as crispy as fresh butternut squash or butternut squash fries.
- Also avoid overcrowding your air fryer – this way the butternut squash can cook evenly and won’t get too mushy.
We use this air fryer for our recipes and it has been great.

It might be helpful if you are a visual learner – but it’s really quite easy!
If you just want to get started making air-fried frozen butternut squash cubes, you can also find the cooking times and temperatures in the recipe card at the bottom of this post!

First, preheat the air fryer to 380 degrees Fahrenheit.
In the meantime, add the frozen butternut squash cubes into a bowl with oil, salt, pepper, and garlic powder.

Toss everything until all the pieces are evenly coated.

When the air fryer is preheated, add the frozen butternut squash into the air fryer basket.
Gently shake the air fryer basket until the squash cubes are evenly distributed – there should be very little overlap to allow for even cooking.

Air fry the frozen butternut squash at 380 degrees Fahrenheit for 10 (smaller cubes) to 18 minutes (larger cubes) until tender.
Shake the air fryer basket approximately every 4 minutes to help with even cooking.
Your exact cooking time can vary by the size of the cubes and your air fryer.

When the squash cubes are tender, remove them from the air fryer and add them to a serving bowl.
You can sprinkle the squash with some chopped parsley before serving. Enjoy!
They go great as a side to dishes like baby potatoes and frozen salmon.
Storage Tips
Once you’ve got air fryer butternut squash from frozen, it’s best enjoyed fresh and eaten right away.
You can store leftovers in a sealed container in the fridge – but the excess moisture might make them very soft. It’ll last for around 4 days.
To reheat any leftover butternut squash cubes, we’d recommend the air fryer to help draw out some of the moisture!

Hi Lisa – your recipes are so great because I can follow them easily but the food never tastes ordinary or dull. Your recipes are tasty! Please can you kindly explain why you sometimes say to use avocado oil and sometimes olive oil. Can I use whichever one I like best or is it important to use the one you specify? Thank you so much!
I’m so glad you like the recipes, Gillian – thanks for your comment! The reason it sometimes says avocado oil and sometimes olive oil is because I personally use mainly avocado oil when I cook, while Yuliia (one of our awesome team members) prefers olive oil – so her recipes will usually call for olive oil and mine will call for avocado oil. In general, you can use whatever oil you prefer for our air fryer recipes. However, when cooking at high temperatures (starting at around 375°F – 400°F +), I personally prefer to use avocado oil (or alternatively canola oil) because it has a higher smoke point than olive oil. Hope this makes sense! /Lisa
