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?
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.
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 Crispy Fried Onions?
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.
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.
