How to Make It
Melt butter in medium saucepan over medium/low heat. Add the garlic, evaporated milk, chicken bouillon and white pepper. In a small bowl, combine cornstarch and regular milk. Whisk until well combined, then pour into the saucepan with other ingredients. Bring mixture to a simmer, stirring often.
Add the Parmesan cheese and continue to simmer for 5-8 minutes or until sauce has thickened and is smooth. When sauce has thickened add the mozzarella cheese and stir until smooth.
While the sauce cooks, boil noodles in well-salted water until they are cooked al dente. Place pasta on serving plates and spoon sauce over pasta. Sprinkle with parsley.
