This isn't the healthiest recipe, but it sure is yummy!  The original recipe calls it a creamy pasta, but it's basically an alfredo sauce and penne.
Ingredients
    * 2 cups penne pasta, uncooked
    * 1 tablespoons butter
    * 4 1/2 teaspoons extra-virgin olive oil
    * 1 tablespoons all-purpose flour
    * 1 teaspoons fresh garlic, minced
    * salt, to taste
    * 1/2 teaspoon dried basil
    * crushed red pepper flakes, to taste
    * 3/8 cup half-and-half (I used half heavy cream and half 1%milk)
    * 1/4 cup chicken broth
    * 2 tablespoons water
    * 3/8 cup parmesan cheese, grated
    * 2 tablespoons sour cream
Directions
   1. Cook pasta according to package directions.
   2. Meanwhile, in a small saucepan, melt butter.
   3. Stir in the oil, flour, garlic and seasonings until blended.
   4. Gradually add the half and half, broth and water.
   5. Bring to a boil; cook and stir for 2 minutes or until slightly thickened.
   6. Remove from heat; stir in cheese and sour cream.
   7. Drain pasta and toss with the sauce.
I added chicken and broccoli and it was a big hit with my picky family.
