This air fryer acorn squash is coated in Parmesan before cooking, then finished with fresh thyme for a savory seasonal appetizer. A little maple syrup complements the squash’s natural sweetness, and the optional creamy thyme dip makes these half-moons especially fun to dunk.
One of my favorite things about acorn squash? I don’t have to peel it. I love cooking with squash, but peeling it is the part I could happily skip forever. Here, the skin stays on—just wash the squash well and remove the seeds before slicing.
Why I Love This Parmesan Acorn Squash
- No Peeling: The edible acorn squash skin stays on, so there’s one less prep task between me and a plate of squash.
- Parmesan Before Cooking: This isn’t just cheese sprinkled over the finished squash. The slices are coated before they go into the air fryer.
- Savory With A Little Sweetness: Parmesan, pepper, and fresh thyme balance a small splash of maple syrup.
- Made For Dipping: The half-moon slices make a fun fall appetizer with the optional Greek yogurt and thyme dip.
Featured Ingredients
- Acorn Squash: Use one squash weighing about 2 pounds. The recipe uses skin-on, ½-inch-thick half-moons—not peeled fries or stuffed squash halves.
- Grated Parmesan: Coats the squash before air frying for the cheesy flavor that makes this version stand out.
- Olive Oil And Maple Syrup: Help coat the slices while adding richness and a little sweetness.
- Fresh Thyme: Finishes the squash and flavors the optional dip.
- Greek Yogurt And Mayonnaise: Form the creamy base of the dip. Serve it alongside the squash rather than coating the squash with it.
Tips For Tender Squash And A Cheesy Coating
Even slices matter. Keep the half-moons about ½ inch thick so they cook at a similar rate. A stable cutting board and a sharp knife are especially helpful with firm winter squash.
Give the squash room. Arrange the slices in a single layer and cook in batches if needed. Crowding limits the hot air circulating around the squash. The 6–8-minute cooking window is per batch; the total time will depend on how many slices fit in your basket.
Check tenderness, not just the clock. The flesh should be fork-tender before serving. Air fryers vary, so continue cooking as needed if your slices are still firm. The skin is edible, but its texture can vary—you can leave any tougher bits on your plate.
How I Serve It
I like serving these Parmesan-coated squash slices as a seasonal appetizer with the creamy thyme dip on the side. They also work as a vegetable side dish when dinner needs a little fall flavor.
For a different squash appetizer, try my air fryer butternut squash fries with hot honey. Those use peeled sticks and a breadcrumb coating; this version keeps the acorn squash skin on and takes a Parmesan-and-thyme approach. If you’re looking for an oven option, try roasted delicata squash.
Storage And Reheating
Refrigerate leftover squash and dip in separate covered containers within 2 hours and use within 3–4 days. Reheat the squash in the air fryer until heated through to 165°F, checking often to avoid over-browning the cheese. Keep the dip cold. The squash is best freshly cooked; refrigerated leftovers will have a softer coating.

Parmesan Acorn Squash
Optional Thyme Dip
-
Preheat the air fryer to 400°F. Wash the acorn squash, halve it on a stable cutting board, and scoop out the seeds. Leave the skin on and cut the squash into ½-inch-thick half-moons.
-
Add the olive oil, maple syrup, kosher salt, and ground black pepper to a large bowl; whisk to combine.
-
Add the squash half-moons to the large bowl and toss to coat evenly with the olive oil mixture.
-
Sprinkle the grated Parmesan over the squash and toss to coat the slices before air frying.
-
Arrange the coated squash slices in the air-fryer basket in a single layer. Air fry at 400°F for 6–8 minutes, checking for fork-tender flesh and continuing to cook as needed. Depending on the size of the basket, cook in batches so the slices are not crowded; the cooking time is per batch.
-
Garnish with fresh thyme.
-
If serving with dip, mix all dip ingredients together and stir to combine.
- No peeling needed: the acorn squash skin is edible. Wash well and remove the seeds before slicing.
- Use ½-inch-thick half-moons for the main recipe. Allow extra time if multiple batches are needed.
- Alternate preparation from the tested brief: for plain squash halves, preheat the air fryer to 400°F. Halve the squash lengthwise and remove the seeds. Drizzle 2 tablespoons olive oil over both halves and season with salt and pepper. Air fry cut-side up for 12–15 minutes, or until fork-tender, continuing to cook if needed. This is a separate preparation, not the Parmesan-coated slice method.
- Refrigerate squash and dip separately within 2 hours and use within 3–4 days. Reheat squash to 165°F; keep the dip cold.
