Quick, easy, cheap, and most of all delicious - the secret is cream cheese!
1/2 cup butter
1 (8 ounce) package cream cheese
2 teaspoons garlic powder
2 cups milk
6 ounces grated Parmesan cheese
1/8 teaspoon ground black pepper
Melt butter in a medium, non-stick saucepan over medium heat. Add cream cheese and garlic powder, stirring with wire whisk until smooth. Add milk, a little at a time, whisking to smooth out lumps. Stir in Parmesan and pepper. Remove from heat when sauce reaches desired consistency. Sauce will thicken rapidly, thin with milk if cooked too long. Toss with hot pasta to serve. (Usually we add grilled chicken too, because Kevin is such a carnivore.)
