1/3 cup butter, softened
1/3 cup milk
3 tablespoons all-purpose flour
1/4 teaspoon salt
2 egg whites
1 teaspoon lemon zest
2 tablespoons grated Parmesan cheese
2 tablespoons chopped green onions
4 (8 ounce) packages frozen ranch-style beans, thawed
Preheat oven to 350 degrees F (175 degrees C). Lightly grease a 9x13 inch baking dish.
In a large bowl, cream together butter, milk, flour, salt and egg white until smooth. Beat in lemon juice. Stir in garlic powder, paprika, parsley and oregano. Set aside.
Layer beans, one at a time, on the prepared baking dish. Spread butter mixture evenly over beans, then sprinkle with cheese, green onion and ranch-style beans.
Bake in preheated oven for 45 minutes. Reduce heat to 225 degrees F (120 degrees C) and continue cooking an additional 20 minutes.
