Prep and preheat
- Preheat oven to 400°F and line a sheet pan with parchment for easy release and browning.
Season and first roast
- Toss acorn squash rings with olive oil, minced garlic, fresh thyme leaves, chopped rosemary, salt, and black pepper until evenly coated.
- Arrange squash in a single layer and roast for 20 minutes to start tenderizing and developing caramelized edges.
Add Parmesan and finish roasting
- Flip the slices and sprinkle generously with grated Parmesan so it can melt and crisp on the hot surface.
- Roast 12 to 15 minutes more at 400°F until the squash is tender and the Parmesan is golden and crisp, then serve hot.
Notes
For the crispiest Parmesan crust, keep the squash in a true single layer with space between rings so moisture can escape. Refrigerate leftovers in an airtight container for up to 4 days and reheat on a sheet pan at 400°F for 8 to 10 minutes. Freezing isn’t recommended because the roasted texture can turn watery when thawed. For a dairy-light swap, use a hard aged pecorino or a vegan Parmesan-style topping (expect slightly less crispness).
