    a copycat French's fried onions recipe made gluten-free, baked to perfection, and unbelievably crispy. Our gluten-free fried onions are perfect for topping your green bean casserole, salads, or burgers. But we even like them on their own for the easiest gluten-free shoestring onion rings ever!

    When working on an updated green bean casserole recipe (i.e. deconstructed, from scratch mushroom pecorino sauce- yum!) for Thanksgiving I wanted something crunchy on top. I tried almonds but at the end of the day, nothing is better than fried onions.

    I found myself eating them non-stop and had to make another batch. That is when I realized these babies were basically gluten-free onion rings and I had to share my technique for homemade french fried onions.

    Why we love this recipe:

    • Gluten-free
    • Dairy-free/ vegan option (see variations below)
    • Bake not fried, making these a healthy snack

    🧾 Recipe Ingredients

    This recipe contains easy to find ingredients. The key is to not overdo in on seasonings and let the onion be the star of the show.

    ingredients for GF fried onions on counter
    • Onion
    • Buttermilk
    • Olive oil 
    • Rice flour
    • Cornmeal
    • Kosher salt
    • Garlic powder

    I prefer to use a white onion or yellow onion. Avoid Vidalia onions if using as a topping, it will be too sweet. But Vidalia onions are great for onion rings. Yum!

    Red onions are fine, but they don't hold up to reheating as well.

    See the recipe card for quantities.

    ⏲️ Instructions

    Now that we have our ingredients let's review step by step how to make gluten-free french's fried onions from scratch. It is a simple recipe but as will simple recipes the key to success is in the details.

    Step 1- Prep the Onions

    The primary use for this recipe is a fried onion topping for casseroles. Therefore the onion needs to be sliced very thinly. I prefer in half-moons but you can also quarter.

    thinly slicing onions

    If you plan on serving as onion straws, cut into very thin rounds.

    Soak the onions in buttermilk for 10 minutes. Soaking the onions in buttermilk will tone down the sharp bite that the sulfur gives off. It also helps the crunchy coating to adhere to the onion.

    Step 2- Coat the Onions

    Mix all the dry ingredients in a bowl (or for less clean up a freezer bag).

    Remove the onions from the buttermilk. Give them a good shake or drain in a colander. You don't want them totally dry but also not sopping wet.

    Add the onions to the bag or bowl. Toss to coat thoroughly. There shouldn't be much if any, excess coating left.

    Step 3- Bake

    Preheat the oven to 425 F degrees. Brush half the oil on a sheet pan.

    Spread out the onions. Don't worry about shaking off excess coating, we want it all! Use a pastry brush to brush the remaining oil over the onions.

    Bake in the preheated oven, tossing onions occasionally, until crisped and golden, about 30 minutes. Expect a few pieces to get burnt, onions tend to do that. You can discard them.

    🥗 How to Use Fried Onions

    • On green bean casserole
    • On top of cast-iron seared bavette steaks
    • On top of a fancy burger
    • In place of croutons on salads
    • Eat plain, with ketchup or siracha mayo

    Note: Easy siracha mayo is ¼ mayonnaise mixed with 1 tablespoon sriracha sauce

    🥘 Tips and Tricks

    • The high heat is one of the reasons I recommend making these in advanced if serving on Thanksgiving, easter, or another holiday. Nothing else will cook at this high of a temperature (425 F).

    💭 Variations

    Dairy-Free Fried Onions

    Soak the onions in oat milk (or other unsweetened non-dairy milk) with 1 tablespoon of lemon juice.

    Spicy Fried Onions

    Add ¼ teaspoon of cayenne pepper or 1//2 teaspoon cajun seasoning. Highly recommended the cajun seasoning for burgers!

    Air Fryer French Fried Onions

    Just like the baked onions, you will need to divide the oil between the air-fryer basket with oil and the flour-coated onions. Add the onions to the basket and place them in the air fryer.

    Depending on your air fryer you will likely need to cook in batches. Cook the onions at 375 F for 10 to 15 minutes, turning halfway through.

    Even if you bake the onions, the air fryer is a great way to reheat.

    🌡️ Making Ahead and Storage

    Gluten-free french fried onions can be made ahead and stored in a sealed container at room temperature.

    To reheat spread on a dry baking sheet and bake at 350 F until heated through. Microwaving is not recommended.

    If using on a casserole, there is no need to reheat if baking on top of a casserole.

    🧾 Best Gluten-Free Fried Onions

    I am partial, I think fried onions are best made from scratch. BUT... we all have time constraints. Luckily at the busiest times of the year (i.e. around major holidays), many stores carry fried onions in gluten-free variations.

    Here are my favorites:

    • 365 brand from Whole Foods
    • Aldi's Live GFree Brand

    They are typically only seasonal items so stock up.

      I love fried onions, and I never thought it could be made gluten free! This is so perfect since my friends coming over for Thanksgiving are gluten intolerant. Thanks so much for the recipe !

      I am always looking for a gluten-free version for fried onions because I have family members with gluten sensitivities. These fried onions look very easy to make.
