Start by cutting the buttercup squash. You can do that by trimming a small portion of the top and bottom of the vegetable. Next, cut it in half and remove the seeds. Once done, cut it into ¼ inch thick slices.
Place the slices on a parchment-lined baking sheet.
In a bowl, mix paprika, cumin powder, salt, and black pepper.
Drizzle olive oil on the butternut squash slices and rub the prepared mixture.
Place the baking sheet in a preheated oven at 425-degree F for about 40 minutes.
Halfway into the cook, remove the baking sheet from the oven, flip the slices and drizzle with olive oil and rub the remaining mixture.
Cook until the buttercup squash gets color and is cooked.
