Enter the number of servings. This green bean casserole batch calculator multiplies servings by 250 grams of casserole and by 150 grams of green beans per serving, so 20 servings give 5000 grams of casserole and 3000 grams of green beans. The sections below explain pan sizes, bean forms, soup and onion quantities, and how the rate compares with competitor serving rules.
The formula is shown on the page: casserole grams = servings × 250, and beans grams = servings × 150. Worked example: for 20 servings, 20 × 250 = 5000 grams of casserole and 20 × 150 = 3000 grams of green beans. For 10 servings, the green bean casserole calculator gives 2500 grams of casserole and 1500 grams of beans. Green bean casserole for 20 people therefore needs 3 kilograms of beans before cooking, and green bean casserole for 10 people needs 1.5 kilograms.
Enter servings, the number of people eating the casserole, and read the casserole and bean totals at once. Use the casserole total as your finished dish weight, the bean total as your bean shopping weight, and the sections below for soup, onions, and pan counts. If the casserole is one of many buffet sides, the buffet section explains when a smaller portion is safe, but the calculator keeps one clear rate so the shopping list stays consistent.
How much green bean casserole do I need per person? Competitor guides disagree: some plan 1/2 cup per person, some 3/4 cup, and some a full cup, with bean weights of 3 to 5 ounces per person. How many pounds of green beans per person? The calculator rate of 150 grams is about 5.3 ounces, at the generous end of that range, which fits a holiday table where casserole is a featured side. Green bean casserole serving size for a buffet with many sides can drop toward 1/2 cup per person, while a featured side at a small dinner can rise to a full cup.

Green bean casserole pan size follows servings: an 8x8 pan serves about 6 to 8 people, a 9x13 pan serves about 12 to 16 people, and a full steam table pan serves about 50 to 64 people. 9x13 green bean casserole servings of 12 to 16 mean green bean casserole for 50 people needs about 3 to 4 pans of 9x13 size.

Bake in two pans rather than overfilling one, so the topping stays crisp and the centre heats evenly.

Serve from a warm pan, replenish from a second pan rather than topping up a cold pan, and return leftovers to the fridge within about 2 hours.
