Easy Onion Strings Recipe
What are Onion Strings? They’re thinly sliced onions that are soaked in buttermilk then coated in a flavorful breading and deep fried until crispy. This recipe includes a bonus dipping sauce to go along with the onion strings made with sriracha ketchup. Enjoy them piled high on a burger, s a topping for salads or steak or as a topping for barbecue chicken sandwiches. Of course, they make a delicious appetizer, too! They’re crispy and golden with just the right amount of seasoning to make the flavor pop. These Onion Strings are deep fried but you can make them in an air fryer too! How to Make Air Fryer Onion Strings:
- Preheat the Air Fryer to 350°F. Coat the basket liberally with cooking spray or brush with oil.
- Prepare the onion strings per the recipe.
- Spray the onion strings with cooking spray on all sides or use an oil mister to coat the breading. Arrange in the basket in a single layer.
- Cook for 8 minutes stopping halfway through to shake the basket (or flip) coating any dry spots again with cooking spray, if needed.
- Keep warm when cooking in batches in a 200°F oven on a sheet pan.
How to Make the BEST Onion Strings Recipe
- Ingredients you’ll need to make homemade fried Onion Strings: Two large sweet onions, buttermilk, sriracha or hot sauce, all-purpose flour, seasoned salt, smoked paprika, garlic powder, black pepper, cumin, dar chili powder and peanut oil or vegetable oil for frying.
- Ingredients you’ll need to make the Sriracha Dipping Sauce: Mayonnaise, Heinz Tomato Ketchup Blended with Sriracha OR plain ketchup, sour cream, garlic cloves, green onions, prepared horseradish, seasoned salt, smoked paprika and black pepper ground.
- Kitchen tools you’ll need: A Dutch oven, fry thermometer, stainless steel spider or slotted spoon, whisk, measuring cups and spoons, sharp knife and cutting board, shallow bowls for the dredging station.
- You can use classic ketchup in place of sriracha ketchup for the sauce. When doing so, add hot sauce or sriracha sauce to your taste.
- It’s important to thinly slice the onions when making onion strings. If you have knife skills, you’re good to go. Otherwise, you can use a mandolin to slice them thinly and evenly.
- The sauce is optional but it goes so well with these for serving. You can easily make it up to 2 days in advance then store it in an airtight container chilled in the refrigerator until serving.
- Onion Strings are best made and served piping hot. Should you have any leftover you can reheat them in a 350°F air fryer or on a sheet pan in a 375°F oven just until crisp.
