Preheat the oven to 425°F (220°C). Line a baking sheet with parchment paper or lightly grease it.
Place the cubed butternut squash on the prepared baking sheet. Drizzle with olive oil and sprinkle with salt, pepper, garlic powder, and paprika if using. Toss gently to coat evenly.
Spread the squash in a single layer, making sure not to overcrowd the pan for even roasting.
Roast in the preheated oven for 25–30 minutes, flipping halfway through, until the edges are golden brown and the squash is tender when pierced with a fork.
Remove from the oven, taste and adjust seasoning if needed. Serve warm as a side dish or over greens for a light meal.
Notes
Perfect as a healthy side dish or paired with grilled proteins.
