Squash and zucchini are two of the most versatile vegetables in the culinary world. Their subtle flavors and tender textures make them perfect for both simple sides and complex dishes. Yet, cooking them perfectly can be tricky-too long, and they become mushy; too short, and they remain raw and underwhelming. Enter the air fryer: a modern kitchen marvel that delivers crispy edges and tender insides with minimal oil. Unlike traditional roasting or sautéing, the air fryer circulates hot air at high speed, creating a unique texture while preserving nutrients and enhancing flavor. In this guide, we’ll explore everything you need to know to master air-fried squash and zucchini, from temperature control to timing, troubleshooting, and expert tips.
Choosing the right temperature is the cornerstone of perfectly cooked squash and zucchini. Too low a temperature and the vegetables steam rather than roast, resulting in a soggy texture. Too high, and the outside may burn before the interior softens.
For most air fryers, the optimal cooking temperature for squash and zucchini is 375°F (190°C). This temperature ensures a balance between caramelization and tenderness. It allows the natural sugars in the vegetables to brown slightly, creating a mild sweetness and a lightly crisp exterior.
If your squash or zucchini is cut into thin slices or small cubes, you might lower the temperature slightly to 350°F (175°C) to prevent over-browning. For thicker chunks or spears, sticking with 375°F (190°C) or even slightly higher (400°F/200°C) for a short duration can help achieve a golden, roasted exterior without undercooking the interior.

Cooking time varies depending on the size, cut, and type of squash or zucchini. As a general guideline:
Always shake or flip the vegetables halfway through the cooking process. This ensures even exposure to the hot circulating air and prevents one side from overcooking. Remember, air fryers vary slightly in intensity, so keep a watchful eye, especially the first time you try a recipe.
Determining doneness is about texture, color, and aroma:
Avoid relying solely on time; visual and tactile cues are more reliable indicators.
To make air-fried squash and zucchini, you will need:
The ingredients are minimal, but they highlight the natural flavors of the vegetables while allowing the air fryer to do the heavy lifting.
Adjusting the temperature should always be balanced with careful timing to avoid undesirable textures.
Cooking times should always be guided by the thickness of your pieces and your preferred texture.
Even with an air fryer, things can occasionally go awry:
Monitoring and adjusting as you cook is part of the learning curve.
Start by washing the vegetables thoroughly. Trim the ends, then cut them into uniform slices, sticks, or cubes to ensure even cooking. Lightly coat them with olive oil and season with salt, pepper, or your preferred spices before air frying.
The optimal temperature for cooking squash and zucchini in an air fryer is typically 375°F (190°C). This allows the vegetables to cook evenly while developing a lightly crispy exterior.
Cooking time usually ranges from 10 to 15 minutes, depending on the size and thickness of the pieces. Shake or toss the basket halfway through to promote even browning.
Soaking is not necessary for squash and zucchini. However, if you want a slightly crisper texture, you can sprinkle them lightly with salt and let them sit for 10-15 minutes to draw out excess moisture, then pat dry before cooking.
Yes, you can cook them with other vegetables that have similar cooking times, such as bell peppers, carrots, or asparagus. Ensure all pieces are cut to uniform sizes for consistent cooking and avoid overcrowding the basket.
For a crispier texture, lightly coat the vegetables with oil and avoid overlapping pieces. Using a small amount of cornstarch or breadcrumbs can also add extra crunch. Additionally, shaking the basket halfway through cooking helps prevent sogginess.
Allow the vegetables to cool completely, then store them in an airtight container in the refrigerator for up to 3 days. Reheat in the air fryer at 350°F (175°C) for 3-5 minutes to restore crispness.
