How much gravy do I need for 6 adults?
How much gravy do I need for 6 adults? Gravy. A little bit of gravy goes a long way, but it's just too sad to run out, and you want leftover gravy if you have leftover turkey. Allot at least 1/3 cup gravy per guest, and have about one extra cup for every six people. How much gravy do I need for 4 people? You'll want 1/3 – 1/2 of a cup of gravy per person. So if you need 6 servings then you want 2-3 cups. I tend to go with the higher amount because I like leftover gravy....
