There are two things in this world that can be paired with almost anything and they instantly make the dish better. One: Homemade Taco Salad Bowls. And the second? These crispy 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 (my Thanksgiving nemesis), but why stop there? Try them on top of Whole30 Potato Soup, Healthy Cauliflower Soup, Air Fryer Sweet Potatoes, or as the perfect crunchy topping on Pressure Cooker Chicken Tacos.
And if you’re smart (and I know you are), you’ll find a way to pair your fried onion straws with Sweet Potato Fries Dipping Sauce. Make it happen.
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.
Pro Tips/Recipe Notes
- If you consume gluten and dairy, feel free to use all-purpose flour and regular milk.
- Cornstarch can be subbed in for the potato starch.
- If you follow a keto/paleo lifestyle, use all almond flour instead of adding the potato starch. Or, use 2 tbsp of arrowroot powder.
How to Store Gluten-Free Fried Onions
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.
How Far Ahead Can I Make These?
These onion straws can be stored for two days before using. 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 degrees.

Gluten Free French Fried Onions
Ingredients
- 3 cups onion {about 2 medium onions}
- 1 cup coconut milk
- 3/4 cup almond flour
- 1/3 cup potato starch
- 1/2 tsp sea salt
- 1 tsp black pepper
- 2 tsp olive oil {more for oven baking}
Instructions
Air Fryer Instructions
- Slice the onion in half and then made "ribbons" about 1/8 inch thick. Separate all the onions and add them to a bowl.
- Pour milk over the onions and use a spoon to push down the onions so they're mostly covered by the milk. Let sit for 10-15 minutes.
- Meanwhile, mix the dry ingredients in a lidded container. Set aside.
- 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 air fryer at 400 degrees 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.
- Lightly spray 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 (took 20 minutes total for me).
Oven-Baked Instructions
- Preheat oven to 425 degrees.
- 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 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.
