Roasted butternut squash is so good on its own that barely any seasoning is needed! In this simple recipe, we focus on the basics — olive oil, garlic, salt, and pepper — and leave any additional garnishes up to you (though chopped parsley, shaved Parmesan, and toasted pine nuts make quite a statement!) This quick and easy butternut squash recipe is perfect for weeknight meals or holiday gatherings. To save prep time, look for pre-cut, peeled butternut squash cubes in your grocery store.
Preheat the oven to 400 degrees F (200 degrees C).
Peel butternut squash with a sharp vegetable peeler. Cut in half lengthwise; scoop out and discard seeds. Cut halves into 1-inch slices, then cut slices into 1-inch cubes.
Combine butternut squash cubes, olive oil, and garlic in a large bowl and toss until well coated. Season with salt and pepper. Arrange in a single layer on a baking sheet.
Roast in the preheated oven until squash is lightly browned and tender when pierced with a fork, 25 to 35 minutes.
