Why We Love It

It’s obvious that I love cooking in my air fryer. I use it for everything from Prosciutto Egg Cups to Mini Burgers to Frozen French Fries!

But one of my new favorite healthy dishes to prepare is this awesome air fryer zucchini and onions recipe! It’s the perfect summertime side dish, great to serve beside a burger, chicken, pork chops, or eggs at any time of day.

And because this air fried zucchini has no breading and less oil, it’s better for you!

Recipe Ingredients

The seasoning ingredients showing individually in small dishes, labeled: garlic powder, oil, oregano, basil, salt, and pepper.
  • Zucchini: I like to choose zucchini that are small to medium. Large zucchini tend to be seedy, which is less than ideal.
    *Note: Feel free to substitute any portion or all of it with summer squash. They have the same cook time!
  • Onion: I prefer to use red onion, but yellow or white onion would work well too.
  • Oil: Olive or Avocado oil are my favorites.
  • Italian Seasonings & Herbs: Basil, Oregano, Garlic Powder, Salt & Pepper.

Making the Recipe

First, preheat your air fryer. This is an important step, so don’t forget to preheat it!

Next, wash and dice the zucchini and onion. Make sure to dice them at least twice the size of the holes in your air fryer. If you dice too small, your air fryer zucchini will fall through the holes once they begin to cook down.

Add all the diced vegetables to a large bowl. Add the oil and all the Italian seasonings, and mix well to coat.

By now your air fryer should be preheated. I don’t spray the basket first because it is fabulously non-stick, but if your air fryer’s instructions say to always spray the basket or if you just find it works better, then by all means, spray it.

Top down of the vegetables and seasonings in a large stainless steel bowl, with a hand holding the bowl and another hand mixing the ingredients with a wooden spoon.

Next, carefully pour the zucchini into the air fryer. Use a wooden spoon or shake the basket to spread them evenly on the bottom of the basket. Close and set the timer for 20 minutes.

Halfway through cook time, give the basket a good shake or turn all the veggies with a wooden spoon. This will help makes sure the veggies are evenly cooked.

Recipe Tip

Keep a close eye on the veggies the last two to three minutes. Each air fryer convects a little differently, so cook time will be just a tiny bit different.

Just peek inside near the end to make sure none of your veggies are burning.
