Preheat your oven to 425°F (220°C). Slice off the top and bottom ends of each acorn squash, slice them in half lengthwise, and scoop out the seeds. Cut each half into slices about 1-inch thick.
In a large mixing bowl, combine the sliced squash with olive oil, grated parmesan cheese, garlic powder, kosher salt, basil, thyme, and oregano. Toss until each slice is coated.
Place the seasoned squash slices on a parchment-lined baking tray and bake for about 20 to 25 minutes until soft and lightly golden on top.
Transfer the roasted acorn squash onto a serving platter and enjoy!
