A simple recipe to try deep-frying at home without any special equipment besides a thermometer, with addictively good results!
Ingredients
Vegetable oil for frying (NOT olive oil, it will burn)
1 large onion, halved and cut into ¼ inch slices
2 eggs
2 tablespoons milk
1½ cups flour
1 teaspoon seasoning salt (+ more for after frying)
1 tsp black pepper
Instructions
Heat 2 inches of oil to 350 degrees. Make sure to use a sauce pan or Dutch oven with high sides so the oil doesn’t boil over when you add the onions (and don't drop too many in too quickly, or it will bubble up A LOT and flood your stove with hot oil and I don't want that to happen to any of you because YERGH that was an awful clean-up job).
While oil heats, cut onion and separate the slices. Whisk eggs and milk in one dish and mix flour, salt, and pepper in another dish for your assembly line.
When oil is hot (an onion should sizzle immediately when dropped in), work with a handful of onions at a time. Dip them in egg mixture and let excess drip off. Next, dredge in flour, tossing lightly with your clean hand to coat all sides. Place onions carefully in hot oil and cook until golden brown, turning them a bit after 1-2 minutes to brown all sides.
Remove with slotted spoon or tongs and place on folded paper towels to absorb excess oil. Repeat process until all onions are fried. Toss fried onions in a large bowl with more seasoning salt to taste (I add about 1-2 teaspoons: they should be fairly salty, but test as you go so they don't go overboard).
Notes
1 large onion will make about 4 cups of onion strings. Any extras are great for snacking on, or I've frozen half and simply reheated them for a few minutes in the oven on a baking sheet the night I want to use them! They stay crisp and fresh tasting :)
