Campbell's lists its regular Condensed Cream of Mushroom Soup as "Contains: Wheat, Milk, Soy", and McCormick lists French's Original Crispy Fried Onions as "Contains: Wheat" — the onions are coated in wheat flour.
The Full Answer
The classic green bean casserole is green beans, condensed cream of mushroom soup and fried onions on top. The green beans are gluten-free; the other two are not. Campbell's lists its regular Condensed Cream of Mushroom Soup as "Contains: Wheat, Milk, Soy", and McCormick lists French's Original Crispy Fried Onions as "Contains: Wheat" — the onions are coated in wheat flour.
The fix is two swaps. Campbell's makes a Gluten Free Cream of Mushroom Soup, thickened with rice flour, with an allergen line of milk and soy only. For the topping, use a crispy onion product labeled gluten-free, or slice onions thin, toss them in a gluten-free flour and bake or fry them yourself.
At someone else's table, assume the casserole is the classic version unless you saw both cans.
