Fettuccine Alfredo wears fall colors when the sauce takes on the sweet flavor and orange color of pumpkin. Bacon and chipotle chili pepper add a hint of smokiness.
Cook pasta as directed on package. Drain well.
Meanwhile, mix milk, pumpkin, Parmesan cheese, flour, pumpkin pie spice, chipotle chili pepper and salt in medium bowl until well blended. Set aside. Cook bacon in large skillet on medium-high heat until slightly crisp. Remove bacon. Drain on paper towels. Set aside.
