  • To make the fried onions, begin by slicing onions into thin rings
  • Place the onions in a bowl and cover with milk to soak for 5 minutes
  • Combine flours, Real salt and 1/4 tsp. pepper in another bowl
  • Meanwhile, heat oil in a deep fryer
  • Remove a few onion rings from milk and shake excess liquid
  • Toss in the bowl of flour mixture until covered completely
  • Shake excess flour then place in the basket of your deep fryer
  • Fry in oil 3-4 minutes or until golden brown
  • Place on a paper towel lined plate
  • Continue until all onions are cooked
  • For the casserole, preheat the oven to 350 degrees
  • In a 8x8 pan, combine green beans, gluten-free cream of mushroom soup, gluten-free soy sauce, Real salt, pepper and 2/3 c. gluten-free fried onions in a casserole dish
  • Bake 25 minutes at 350 degrees

Be sure to only use yellow or white onions for the homemade fried onions. Purple onions come out dark and unappetizing.
