Roasted spaghetti squash is often accompanied by things like tomatoes, shallots, garlic, and black pepper, to give it a flavor boost. Searching for something different, but not too far out of the realm of the familiar (cacio e pepe pasta inspired us), we decided to pair it with Parmigiano-Reggiano cheese and delicate aromatics. Serve this sweet, delicate-tasting side next to roasted chicken and a simple green salad for a no-fuss supper.
- 1Heat the oven to 400°F and arrange a rack in the middle. Cut the squash in half lengthwise and scrape out the seeds. Brush the flesh with 2 tablespoons of the oil and season generously with salt and pepper. Place the squash halves cut-side up on a baking sheet and roast until fork tender, about 50 minutes.
- 2Remove the squash from the oven and let sit at room temperature until cool enough to handle, about 30 minutes. Scrape the flesh with a fork to make long strands; set aside.
- 3Heat the remaining 2 tablespoons of oil in a large saucepan over medium heat until shimmering, about 3 minutes. Add the garlic and shallot, season with salt and pepper, and cook until softened and lightly browned, about 3 minutes.
- 4Add the reserved squash, toss with tongs to coat thoroughly, and cook until heated through, about 3 minutes. Remove from the heat and add the cheese a handful at a time while tossing the squash to evenly coat. Serve with freshly ground black pepper and extra cheese.
