Pour about 1-1/2 to 2 inches of oil into a deep, heavy-bottomed pot. Heat to 360 degrees F, clipping a candy thermometer to the side of the pot to regulate the temperature.
While the oil is heating, cut as many wonton wrappers as you would like to serve into 3/4-inch wide strips. Keep wontons covered with a towel while you finish heating the oil.
Line a baking sheet or cooling rack with a double layer of paper towels. Set aside.
When the oil reaches temperature, carefully add a handful of wonton strips to the pot. They will immediately puff up. Fry for 1-2 minutes, using a spider strainer or slotted spoon to move them around in the pot. When they're golden brown on all sides, drain them with the spider or slotted spoon and transfer them to the paper towel-lined baking sheet to cool.
Let the oil return to 360 degrees F between each batch of wonton strips. (The temperature will drop about 10 degrees to 350 when the wontons are added.)
Serve crispy wonton strips with duck sauce and/or Chinese mustard for dipping. Or, enjoy them with your favorite soups and salads.
Let the wonton strips cool completely before transferring to an airtight container (I like to use a large cookie tin). They will keep well at room temperature for 1-2 days.
Air fryer Instructions:
You can make wonton strips in the air fryer, but the wontons won't puff up as they do with the hot oil in deep frying. They do come crispy, but it's a different chip in terms of texture. I like them for a lighter snack.To make them, cut wontons into strips and spray them with cooking spray. Lay them by the handful in a single layer in the air fryer basket. Air fry at 350 degrees F for 8-10 minutes, shaking the basket occasionally.Air fryers can vary by model in terms of times and temperatures. Watch your first batch closely to gauge how much time they need.
