My Personal Experience

I first tried making butternut squash in the oven years ago — I’d cut it, season it, and then wait… and wait some more. By the time it was ready, dinner had long been over. Then one day, while testing air fryer recipes for my blog, I tossed in a batch of cubed butternut squash with olive oil and spices.

Ten minutes later, my kitchen smelled like roasted maple heaven. The edges were crisp, the center soft like butter, and I couldn’t stop “taste-testing.” From that day on, this became my go-to side dish for quick weeknight dinners.

Required Equipment

🌀 Air Fryer

Any basket-style or dual-zone air fryer works great. Just make sure it’s at least 4 quarts so your squash has room to crisp up.

🥣 Mixing Bowls

Use a medium bowl for tossing your squash with oil and spices — it ensures even coating and seasoning.

🍴 Tongs or Spatula

To easily flip or shake the squash halfway through cooking.

🧂 Measuring Spoons

Precision matters when you want perfectly balanced seasoning without excess oil or salt.

Ingredients & Substitutions

Here’s what you’ll need to make these Air Fryer Butternut Squash Bites:

• 2 cups butternut squash, peeled and cubed (¾-inch pieces) – Choose fresh, firm squash. You can also use pre-cut cubes from the grocery store to save time.
• 1 tablespoon olive oil – Helps achieve that perfect crispy coating. You can swap with avocado oil for a lighter flavor.
• ½ teaspoon garlic powder – Adds savory depth that balances the sweetness.
• ½ teaspoon smoked paprika – Optional but adds warmth and color.
• ¼ teaspoon salt (or to taste)
• ¼ teaspoon black pepper
• ¼ teaspoon cinnamon or pumpkin pie spice (optional) – For a sweet-savory twist.
• 1 teaspoon grated parmesan (optional for keto) – Adds a crisp, cheesy layer.

Air Fryer Notes

Preheat your air fryer to 390°F (200°C) for 3 minutes before cooking — this ensures that first blast of heat for crisp edges.
Spread the squash in a single layer — overcrowding causes steaming instead of crisping.
Halfway through, shake or toss the basket for even browning.
Finish at 400°F (205°C) for the last 2–3 minutes for a beautiful roasted finish.

How to Make Air Fryer Butternut Squash Bites

Step 1: Prep the Squash

Peel your butternut squash using a sharp peeler, then cut it in half and remove the seeds. Cube it into even ¾-inch pieces — this size cooks evenly and crisps beautifully.

Step 2: Season

In a bowl, toss the cubes with olive oil, garlic powder, paprika, salt, and pepper. For a hint of fall flavor, add cinnamon or pumpkin pie spice.

Step 3: Air Fry

• Preheat air fryer to 390°F (200°C).
• Place seasoned cubes in a single layer in the basket.
• Air fry for 14–16 minutes, shaking halfway.
• Finish at 400°F (205°C) for the final 2 minutes for extra crisp edges.

Step 4: Serve

Transfer to a plate, sprinkle with parmesan or fresh herbs, and enjoy immediately!

Common Mistakes to Avoid

🚫 Overcrowding the basket – Always cook in batches for best crispiness.
🚫 Skipping preheat – Cold air fryer = soggy squash.
🚫 Too much oil – A light drizzle is enough; excess oil softens the cubes.
🚫 Uneven cuts – Different cube sizes cook unevenly.
