Gluten Free Fried Onion Topping (For Green Bean Casserole)

Total Time
Prep 10 mins
Cook 30 mins

If you are gluten free, you can't eat those french fried onions out of a can, the ones that make green bean casserole so indulgent and delicious. This simple recipe, adapted from Alton Brown's recipe (which contains gluten), will make you forget all about that can full of junky processed gluten.

Ingredients Nutrition


  1. Preheat oven to 475. Slice onions in half and then into 1/8 inch slices and toss in a bowl with the flours and salt. Generously grease a baking sheet with about half the oil and evenly spread the onions in the pan. Drizzle the rest of the oil evenly on top of the onions. Place in middle rack and bake until golden brown, about 30 minutes. Toss the onions 2 to 3 times during cooking. Keep a good eye on them towards the end, they can go from a little brown to burnt very fast, and you want to pull them out at the right time!
  2. Use just like the canned onions- Add half to your green bean casserole and put the other half on top, or according to your casserole recipe.

I can't believe I forgot to review this! I used this recipe last year to make green bean casserole since my hubby has gone gluten free. These onions were fabulous, I could not stop eating them just plain. Everyone RAVED about my casserole (including everyone who eats a gluten-full diet). They were so good I made them for Thanksgiving AND Christmas. I am making them again right now! I used mostly sweet onion but a little bit of just regular yellow onion too. Also, I did not have white rice flour so I subbed gluten free baking mix. So yummy, thank you!!!

Thank you so much for sharing this recipe. I make green bean casserole every year at Thanksgiving, especially for my sister who always raves about it. This year she is gluten free and I didn't want her to miss out on it. That's when I found this recipe. EVERYONE said it was better than ever with these onions. I don't think I'll buy the prepared onions ever again!
