Place the butter in a large skillet over low heat, and simmer for about 2 minutes, watching it closely so it doesn’t start to brown, as this will change the flavor. Once the butter melts, sprinkle the flour over the butter and stir for about 1-2 minutes or until it starts to thicken.
Stir in the minced garlic and 1/2 cup chicken broth, bring to a boil, then reduce heat to med-low and let it bubble for about 1 minute.
Whisk in the cream and let the sauce cook for a few minutes until it thickens, stirring constantly (cook it longer for a thicker, creamier consistency, but continue to stir). Season with salt and pepper to taste
Remove from the heat, and stir in the cheese. If the sauce is too thick add the remaining 1/4 cup of broth
Mix the orzo with the corn mixture, then toss in the chicken and add dried basil and dried oregano
