Acorn squash is a small, round winter squash, prized for its sweet, nutty flavor and smooth, tender flesh. Its vibrant orange interior is not only visually appealing but also packed with vitamins A and C, fiber, and antioxidants. While traditionally roasted in the oven, the air fryer has emerged as a game-changing tool for preparing acorn squash. Using an air fryer accelerates cooking, enhances caramelization, and creates a perfectly tender texture without the need for excessive oil. Cooking acorn squash in an air fryer allows for a golden, slightly crispy exterior while keeping the inside luxuriously soft, making it ideal for both side dishes and main courses.
The ideal air fryer temperature for acorn squash typically falls between 375°F and 400°F (190°C-205°C). This temperature range ensures that the flesh softens evenly while the natural sugars in the squash caramelize, producing a slightly sweet, roasted flavor. Temperatures lower than 375°F may result in uneven cooking or a mushy texture, while temperatures higher than 400°F can risk over-browning the edges before the interior is fully cooked. For the best balance of caramelization and tenderness, 390°F (199°C) is often considered the sweet spot for most air fryers.

Cooking time depends on the size of the squash and whether it is halved, quartered, or cubed:
It’s important to note that air fryers can vary in efficiency, so checking doneness a few minutes before the suggested time can prevent overcooking.
Determining if acorn squash is fully cooked requires attention to both texture and appearance:
The beauty of acorn squash is its simplicity. You only need a few basic ingredients:
Using a temperature lower than 375°F will slow down cooking, potentially resulting in unevenly softened squash or an extended cooking time. Conversely, temperatures above 400°F can brown the surface too quickly, leaving the interior undercooked. Adjusting temperature should always be accompanied by careful monitoring of the squash, and you may need to extend or shorten the cooking time accordingly.
Cooking for too little time will yield firm, undercooked squash that is starchy and difficult to scoop. Cooking for too long can dry out the flesh or over-caramelize the edges. The best approach is to use the suggested times as a guideline and check the squash with a fork a few minutes early to ensure perfect tenderness.
Start by washing the acorn squash thoroughly. Cut it in half lengthwise and scoop out the seeds and stringy pulp with a spoon. You can leave the skin on, as it becomes tender when cooked. Optionally, you can slice it into wedges or cubes depending on your desired cooking method.
No, peeling is not necessary. The skin is edible and becomes soft enough to eat once the squash is cooked in the air fryer. Leaving the skin on also helps the squash hold its shape and makes handling easier.
Preheat your air fryer to 375°F (190°C). This temperature allows the squash to cook evenly and develop a slightly caramelized surface without burning.
Cooking time varies depending on the size and cut of the squash. Halved acorn squash usually takes 20-25 minutes, while smaller wedges or cubes may take 12-15 minutes. Check for tenderness by inserting a fork; the squash should pierce easily.
Yes, seasoning enhances flavor. Common options include olive oil, salt, pepper, cinnamon, or brown sugar. Coat the squash evenly with your chosen seasonings before placing it in the air fryer basket for optimal taste and caramelization.
It is possible, but fresh squash is recommended for the best texture and flavor. If using frozen squash, thaw it first to avoid uneven cooking. You may need to increase the cooking time slightly to ensure it cooks through.
Allow the squash to cool completely, then transfer it to an airtight container. Store in the refrigerator for up to 3-4 days. Reheat in the air fryer or microwave before serving, and avoid reheating multiple times to maintain texture and flavor.
