You’re in for a treat with these Gluten-Free French Fried Onions! These fried onion strings can be made in the air fryer or baked in the oven.
There are two things in this world that can be paired with almost anything and they instantly make the dish better. The first? Homemade Taco Salad Bowls.
And the second? These gluten free French fried onions.
Crispy fried onions, which might also be called onion straws or crispy onion strings are hopelessly delicious. Most people put them on top of green bean casserole but why stop there?
Ingredient highlights
- Coconut milk – I used canned, but you can also use shelf-stable, refrigerated, or your favorite non-dairy milk.
- Almond flour – it’s my favorite for breading ingredients, but if you have a favorite gluten-free flour, feel free to use it.
- Potato starch – cornstarch works great too.
What Kind of Onions Work Best for Shoestring Onions?
If you want a strong onion flavor, use white or yellow onions. Sweet onions (like Walla Walla or Vidalia) work great if you don’t want the onion flavor to be overwhelming.
If you have any leftover onions, whip up a batch of Pressure Cooker Caramelized Onions.
How Far Ahead Can I Make Crispy Fried Onions?
These onion straws can be stored for two days before using them. They will lose some of their crunch but can be quickly reheated to crisp up again. I popped ours back into the air fryer for 1 minute at 400˚F.
Pro Tips/Recipe Notes
- If you consume gluten and dairy, feel free to use all-purpose flour and regular milk.
- Allow the fried onions to fully cool before storing them in an air-tight container. Onions that are still warm will put out heat, causing condensation in the container. Any moisture trapped with the onions will cause the breading to become soggy. Store at room temperature.

Instructions
Air Fryer Instructions

- Drain the onions, shaking the excess milk off. Place onions in the flour mixture. Put the lid on and shake until the onions are coated.
- Preheat the air fryer to 400˚F for 5 minutes.
- Using clean hands, remove the onion from the flour mixture and set aside. In another bowl, add the olive oil. Add the onions to the olive oil and stir or shake to coat.2 tsp olive oil
- Lightly brush the inside of the air fryer with olive oil and add the onions. Cook for 8 minutes, and then shake the basket to distribute the onions.
- Cook for another 5 minutes. Pro tip: spritz with olive oil on top to keep the onions extra crispy!
- Continue to cook in 3-minute increments until it has reached your desired level of crispiness (~20 minutes total for me).
Oven-Baking Instructions
- Preheat oven to 425˚F.
- Follow steps 1-4 and 6 above.
- For oven-baking, you’ll need to use 1/4 cup olive oil.
- Bake on rimmed baking sheet for 10 minutes. Stir, and bake an additional 10-15 minutes.

Hi I’m on a low carb diet and potato starch is out of the question. Can you recommend an alternative for it that’s low carb? I have some xanthan gum but I’m not sure if it’s a 1:1 ratio or not.
Thanks
I would replace it with more almond flour.
I know some people who do keto grind-up pork rinds to use as breading. If you’re not vegetarian, that would likely work very well here!
Hi Sarah – will this recipe work with 2% milk rather than coconut milk? They look delicious in the pictures!
Yes! Any milk will work. The absolute best is buttermilk if you have any on hand.
Hi Sara,
Nice recipe! I wonder how the shelf life can be extended? Do you know if dehydrating the fried onions afterwards would do the trick? And if so – for how long will they last?

William, I’m just not sure. But if you try it out, please report back and I can update the post!
Oh my gosh! I was just looking for a gluten and dairy free French fried onion recipe today! I have a really good dairy-free from-scratch green bean casserole recipe (grandson), but now both my daughters are gluten free because of thyroid issues. So I can now make these rather than just opening a can. Doesn’t matter much for one of my daughters — she has found out she is also allergic to green beans! Along with eggs. Wish me luck as I embark upon our dairy-free, egg-free, gluten free Thanksgiving! Sorry Kid, can’t do without my green bean casserole and Grandma’s stuffing!
Oh my goodness that is a lot of moving parts for a big meal!
Who is allergic to green beans?! That’s a new one! Your poor daughter.
