Preheat the oven to 400°F.
Cut the acorn squash in half, lengthwise, and take out the seeds.
Slice each acorn squash half into ½-inch thick slices.
Transfer the squash slices to a parchment lined baking sheet.
Melt the butter.
Add the oregano, thyme, garlic powder, paprika, salt, and pepper to the butter, and stir well to combine.
Brush the squash slices with the butter mixture.
Roast in the preheated oven for 20 to 25 minutes, or until the squash is tender and cooked through.
Remove from oven. Taste for salt and pepper; adjust accordingly.
Garnish with parsley and serve.
