One-Pot Butternut Squash Mac & Cheese is about to become your autumn staple! By cooking the pasta directly in a velvety base of roasted butternut squash, butter, and water, every single noodle absorbs rich, savory flavor as it cooks. Blended with tangy cream cheese, sharp cheddar, and nutty Parmesan, the squash creates a smooth, hidden-veggie sauce that feels luxurious without being overly heavy. It's warm, cheesy, and packed with seasonal goodness!
