Why You’ll Love This Air Fryer Zucchini and Squash Recipe

Simple Ingredients with Big Flavor

You don’t need a long list of ingredients or complicated techniques to make something delicious. This air fryer zucchini and squash recipe keeps things straightforward. With just a touch of olive oil, a few dried herbs, and a sprinkle of garlic and onion powder, the natural flavor of the squash shines through. There’s no breading, no cheese (unless you want to sprinkle some on top), and no fuss—just real food, fast.

The herbs—like basil and oregano—add an Italian twist, making it easy to pair with grilled meats, pasta, or as a healthy snack all on its own.

Fast and Foolproof: Just 20 Minutes

Let’s be honest—most people aren’t spending hours in the kitchen during the summer. This air fryer zucchini and squash dish is ready in under 20 minutes, from prep to plate. You’ll only need 5 minutes of hands-on prep, and the air fryer does the rest.

Crispy, Golden, and Perfectly Tender

The real magic of this recipe happens in the air fryer. Unlike roasting or sautéing, the hot air circulates around every slice of squash, giving it crispy edges and a tender bite—without turning it to mush.

By tossing the veggies once midway through cooking, you get even browning and that irresistible texture that keeps everyone coming back for seconds.

• Gluten-free
• Low-carb
• Keto-friendly
• Vegetarian & vegan
• Paleo & Whole30 compliant

If you’re watching your carbs, avoiding processed ingredients, or just trying to eat more vegetables, this dish checks every box. One serving is light on calories but packed with flavor and fiber.

Step-by-Step Cooking Instructions

Step 1: Preheat Your Air Fryer

Start by preheating your air fryer to 400°F for about 3 minutes. This helps the air fryer reach an even temperature and gives your squash that perfect golden finish from the get-go. Skipping this step can result in uneven cooking or soggy slices.

If your air fryer doesn’t have a preheat function, just run it empty at 400°F for 3 minutes before adding the squash.

Step 2: Prepare the Seasoning Blend

In a small bowl, mix together the following:

• 1/4 teaspoon dried basil
• 1/4 teaspoon dried oregano
• 1/4 teaspoon kosher salt
• 1/8 teaspoon garlic powder
• 1/8 teaspoon onion powder
• A pinch of black pepper

This simple blend is flavorful but mild enough to let the squash’s natural taste shine.

Step 3: Season the Zucchini and Squash

Place the 6 cups of sliced zucchini and yellow squash into a medium-sized mixing bowl. Drizzle them with 1 teaspoon of olive oil, then sprinkle the seasoning blend over the top.

Use your hands or a spatula to toss the slices until every piece is lightly coated in oil and herbs. This step ensures that the squash cooks evenly and crisps nicely on all sides.

Step 4: Load the Air Fryer Basket

Transfer the seasoned squash slices to your air fryer basket. Spread them out in a single layer as much as possible, but don’t stress if they overlap slightly—some overlapping is normal and won’t ruin the results.

The key is airflow. The hot circulating air is what gives you those crispy edges, so try not to pile the slices too deep.

Step 5: Air Fry and Toss

Air fry the zucchini and squash at 400°F for 10 to 15 minutes, depending on how thick your slices are and how crispy you like them. At the halfway mark (around 5 to 7 minutes), give the basket a quick shake or use tongs to toss the veggies.

This flip helps all sides cook evenly and prevents sticking. If you’re using a smaller air fryer, you may need to work in two batches.

Step 6: Serve and Enjoy

Once the squash is golden around the edges and tender in the center, remove it from the air fryer basket. Taste and adjust seasoning if needed—sometimes a pinch of flaky sea salt at the end really elevates things.

Serve immediately while warm and crisp!

Tips to Avoid Mushy Zucchini and Squash

Moisture Is the Enemy: Pat Them Dry First

Zucchini and yellow squash contain a lot of natural water, especially during the summer months when they’re at peak ripeness. If you skip drying them, that moisture steams the vegetables instead of crisping them—leaving you with a limp, mushy mess.

Here’s what to do:

• After slicing your squash, lay them on a paper towel or clean kitchen cloth.
• Lightly press another towel over the top to absorb excess moisture.
• Let them sit for 5–10 minutes if time allows.

This one simple step makes a huge difference in the final texture.

Don’t Overcrowd the Basket

Your air fryer needs room to breathe. When the basket is too full, air can’t circulate properly, and that leads to soggy, steamed vegetables instead of golden, crispy ones.

Quick tip: It’s okay if some slices overlap slightly, but you should still be able to see the bottom of the basket in some spots. If you’re making a large batch, cook in two rounds.

Use Just Enough Oil—Not Too Much

While a little olive oil helps the seasoning stick and aids browning, too much creates a slippery surface that traps steam instead of letting it escape.

Stick to 1 teaspoon of olive oil per 6 cups of sliced squash—just enough to coat without soaking.

Cook at a High Temperature (400°F)

Low and slow works for roasts—but not for zucchini. To get that caramelized edge and soft-but-not-soggy interior, you need a hot, quick cook.

400°F is the ideal temperature for air frying summer squash. It allows water to evaporate rapidly while the exterior crisps up.

Toss Halfway for Even Cooking

Even if your air fryer claims to be “set-it-and-forget-it,” you’ll get better results by tossing the basket at the halfway mark. This helps redistribute moisture, exposes new surfaces to direct heat, and avoids soft spots.

Quick Recap: What Causes Mushy Zucchini in the Air Fryer?

Mistake	Fix
Didn’t pat squash dry	Blot with paper towels before seasoning
Overcrowded basket	Cook in smaller batches
Too much oil	Use no more than 1 tsp for 6 cups of squash
Low air fryer temperature	Always use 400°F for crisp-tender results
Didn’t toss or flip halfway	Shake or turn with tongs at the 5–7 minute mark

Common Mistakes to Avoid When Air Frying Zucchini and Squash

1. Skipping the Preheat

One of the biggest mistakes people make is not preheating their air fryer. Just like an oven, your air fryer needs to reach the proper temperature before the food goes in. When it isn’t hot enough from the start, the squash releases too much moisture before it begins to crisp—resulting in soggy slices.

Fix it: Run the air fryer at 400°F for 3 minutes before adding your veggies.

2. Forgetting to Pat Dry

Zucchini and squash contain a lot of water, and if that moisture isn’t reduced before cooking, your veggies will steam instead of fry. Even with high heat, damp vegetables can’t crisp up properly.

Fix it: Blot the sliced squash with paper towels or let them sit on a towel-lined plate for 5–10 minutes to draw out extra moisture.

3. Overcrowding the Basket

Too many squash slices packed into the air fryer prevents air from circulating, leading to uneven cooking and limp veggies. This is especially common when doubling the recipe for a big crowd.

Fix it: Cook in smaller batches and spread the squash in a single layer. Overlap is okay, but don’t pile them up.

4. Using Too Much Oil

While oil is necessary for flavor and texture, too much of it creates a slick surface that traps moisture and hinders browning. A greasy end result also defeats the purpose of a healthy dish.

Fix it: Use just 1 teaspoon of olive oil for the full batch—enough to coat the slices without saturating them.

5. Not Tossing Halfway Through

The bottom layer of squash can get too browned while the top stays undercooked if you leave everything in place. Not tossing leads to uneven results—and possibly burnt edges.

Fix it: Shake the basket or stir with tongs at the halfway mark (around 6–7 minutes in).

6. Ignoring the Thickness of Slices

Thick slices take longer to cook and may stay too soft inside, while thinner ones can burn before they’re fully tender. Uniformity matters.

Fix it: Slice squash into even, medium-thick half-moons—around 1/4 to 1/3 inch thick—for the best balance of texture and cooking time.

7. Not Tasting Before Serving

Even with a great seasoning blend, vegetables sometimes need a final pinch of salt or squeeze of lemon juice right before serving to bring out their full flavor.

Fix it: Taste and adjust at the end—you’re the chef!

Quick Recap Table: Common Air Fryer Mistakes

Mistake	Easy Fix
Didn’t preheat air fryer	Run at 400°F for 3 mins before cooking
Veggies too wet	Blot dry with towels before seasoning
Overcrowded basket	Cook in batches with some space between slices
Too much oil	Stick to 1 tsp olive oil
Didn’t toss halfway	Shake or stir at 6–7 minutes
Slices uneven	Cut squash into uniform, medium-thick pieces
Skipped final tasting	Add lemon or salt before serving for flavor boost

Storing and Reheating Air Fryer Zucchini and Squash

How to Store Leftovers Properly

Air-fried zucchini and squash are best served fresh, but if you do end up with leftovers, don’t toss them! With a few smart storage tips, you can enjoy them later without losing too much of that crisp-tender texture.

Here’s how:

• Let them cool fully before storing. Placing hot veggies into an airtight container creates steam, which makes them soggy.
• Store in a shallow airtight container lined with a paper towel to absorb moisture.
• Keep refrigerated for up to 3 days.

Avoid freezing this dish—zucchini and squash have high water content and will turn mushy when thawed.

Best Way to Reheat Without Losing Texture

Microwaving is fast but makes the squash soft and limp. Instead, use your air fryer again—it revives the crisp edges and keeps the flavor intact.

Reheating Instructions:

• Preheat the air fryer to 350°F
• Place squash in the basket in a single layer
• Reheat for 3–4 minutes, tossing once halfway through

You’ll be surprised how close it tastes to freshly cooked—even on day two or three.

Meal-Prep Tips for Busy Weeks

If you’re prepping ahead, it’s best to store your squash uncooked and seasoned:

1. Slice the zucchini and yellow squash and pat them dry
2. Toss with olive oil and seasoning blend
3. Store in an airtight container in the fridge for up to 24 hours
4. Air fry just before serving

This way, you get fresh texture with minimal effort at dinner time.

How to Use Leftovers Creatively

Leftover air fryer zucchini and squash don’t have to be boring. Use them in:

• Grain bowls with quinoa, feta, and chickpeas
• Egg scrambles or omelets the next morning
• A wrap with hummus and roasted red peppers
• Tossed into pasta with olive oil and garlic
• On top of homemade pizza or flatbread
