How to Make Onion Straws
Prepare the Aioli: In a small bowl, mix together 3 cloves of minced garlic, ¾ cup of mayonnaise, 2 teaspoons of lemon juice, and the minced chipotle pepper. Once combined, cover it and pop it in the refrigerator to chill while you prepare the onion straws. This aioli is a game-changing dip that enhances every bite!
Marinate the Onions: In a wide bowl, add the 2 medium Vidalia onions that you’ve very thinly sliced and cover them with 1 cup of buttermilk. Give it a good stir, and let the onions soak for about an hour, stirring occasionally. This step is crucial as it flavors the onions and makes them tender.
Prep the Dredging Mix: On a shallow plate, whisk together 1 cup of flour, 1 teaspoon of garlic powder, ½ teaspoon of salt, ½ teaspoon of black pepper, 2 teaspoons of cayenne pepper, and 1 teaspoon of smoked paprika. This seasoned flour will give your onion straws that extra crunch and flavor.
Heat the Oil: In a heavy stock pot or Dutch oven, heat canola oil to 375 degrees Fahrenheit. Use a thermometer for accuracy; this ensures your onion straws fry nicely without becoming greasy.
Dredge & Fry the Onions: Using tongs, take the marinated onions from the buttermilk, letting the excess liquid drip off, and dredge them in the flour mixture. Shake off any excess flour. In small batches, carefully add the onions to the hot oil and fry them for about 1-2 minutes or until they’re golden brown, making sure to break them up slightly with tongs as they fry to prevent clumping. You’ll want to keep a close watch on them; they fry quickly!
Drain & Serve: Once golden, remove the onion straws from the oil and drain them on paper towels. Serve warm with the chipotle pepper aioli for dipping. Enjoy every crunchy and flavorful bite!
Storing & Reheating
To store leftover onion straws, keep them in an airtight container at room temperature for up to 2 hours. If you want to store them longer, transfer them to the refrigerator, where they should remain good for about 2 days. You can also freeze them for up to 3 months; just lay them out on a baking sheet to freeze first before transferring to a freezer-safe bag. When it’s time to enjoy again, reheat in a preheated oven at 375 degrees Fahrenheit for about 5-7 minutes until crispy again. Keep in mind that onion straws will lose some crunch; refreshing them in the oven helps regain that texture.
Chef’s Helpful Tips
- Avoid overly thick onion slices; they need to be thin for maximum crunch.
- Let the oil properly heat up before adding the onions—this prevents the batter from getting soggy.
- If the batter isn’t sticking, double-check that you’ve soaked the onions long enough in buttermilk.
- Feel free to customize the spices in the flour; add more heat with additional cayenne if you like.
- Try making the aioli a day in advance to deepen the flavors; just give it a stir before serving.
Onion straws are a wonderful appetizer that not only tastes amazing but is also easy to prepare. With a delightful crunch and a smoky dip, they are sure to be a hit at your next gathering. Feel free to experiment with the spices or even add your own twist to the aioli. Enjoy these crispy treats, and don’t forget to share with friends or savor them all to yourself!
