Preheat oven to 425 degrees F. Line a large baking sheet with parchment paper, leaving an inch of overhang.
On a large cutting board, slice off any woody stems, and then slice squash in half. Scoop out the seeds. Slice into 1-inch thick wedges.
Flipping halfway through, roast squash 35 - 40 minutes total, or until squash are fork tender with crisp, golden edges.
Meanwhile, make the chile oil. I halved Lisa Lin’s recipe, omitted the ginger, and added 1 tablespoon black sesame seeds. Set aside to cool.
When squash are ready, add ¼ cup ricotta to each plate. Add a drizzle of chili oil and a pinch of flaky sea salt. Tuck the squash around the ricotta and drizzle with more chile oil, a touch of maple syrup, fresh herbs, and another pinch of sea salt. Serve right away.
