Melt butter in a large saucepan over medium heat. Add flour and cook for two to three minutes. Add heavy cream; stir constantly until butter-flour mix is incorporated and smooth. Add Afino by Grande Parmesan, garlic and Afino by Grande Ricotta; stir until melted.
Bring sauce to a simmer and cook for seven to ten minutes. Stir constantly. Add salt and pepper to taste. Cool before use, allowing sauce to thicken.
Store in refrigeration or freeze. To reheat, warm Alfredo sauce in a saucepan over low heat, stirring constantly to avoid separation.
