This is a tasty, gluten-free onion topping for casseroles or even to top a hamburger. They are ‘oven-fried’ and are similar to the popular fried-onions-in-a-can that are often used in the traditional green-bean casserole.

Recipe Ingredients

  • 2 tablespoons olive oil, divided
  • ¼ cup rice flour
  • 2 tablespoons cornmeal
  • ½ teaspoon salt
  • 2 large onions, halved and cut into short strips

Cooking Directions

  1. 1 Preheat oven to 425 degrees F (220 degrees C). Oil a baking sheet with 1 tablespoon olive oil.
  2. 2 Mix flour, cornmeal, and salt together in a bowl. Toss onion in flour mixture until coated. Spread onion mixture onto prepared baking sheet. Drizzle remaining oil over onion.
  3. 3 Bake in the preheated oven, tossing onions occasionally, until crisped and golden, about 30 minutes.

Chef's Notes

  1. I made a double batch of these for my gf green bean casserole. I actually fried mine instead of baking them because I wanted them darker brown and crispy without being burnt. It worked out great! I can t stop munching on them...I only hope I have enough for the casserole...
  2. Let s be honest I had to make 2 batches. I ate the first batch before they got on top of the green beans. My husband who is not a fan of the canned ones said these were very good.
  3. KEEPER ALERT! How many recipes have I passed on because they called for french fried onions and I didn't have a gluten free alternative? Too many! Now we don't have to. Don't halve the recipe because you will eat half of them right off the baking sheet. I ended up making two batches one onion - Read more ...
