Preheat the oven to 375 degrees F (190 degrees C).
Combine olive oil, parsley, herbes de Provence, garlic, salt, and pepper in a large bowl. Add butternut squash pieces and toss to coat. Place in a single layer on an ungreased baking sheet.
Bake in the preheated oven until squash is soft, about 15 minutes. Turn squash pieces and bake 10 more minutes. Sprinkle with Parmesan cheese. Bake until golden brown, 15 to 25 minutes more.
