Crispy fried onions are so satisfying. Their golden crunch makes even simple dishes better, like magic. Store-bought ones have preservatives and don’t taste as good as homemade ones. When cooking for one or two, making small batches of crispy fried onions is perfect because you enjoy them at their freshest.
Start by gathering everything you need. Thinly slice onions, and set up your workstation with a bowl of buttermilk and a separate bowl for the whey protein and baking powder mixture.
Soak the onion slices in buttermilk. This not only tenderizes the onions but also helps the coating stick. After soaking, dredge the onions in the whey protein and baking powder mixture, making sure each slice is well-coated. Place the onions on parchment paper after being coated, and be ready to fry.
Heat vegetable oil in your frying pan over medium heat. Once hot oil is ready, add the coated onion slices in small batches. Fry until golden brown and crispy, turning occasionally to ensure even cooking. Remove the onions with tongs and drain on a paper towel lined to remove excess oil.
Notes
Don’t overcrowd the pan: Fry the onions in small batches to ensure they cook evenly and stay crispy.
Keep the oil at the right temperature: Too hot, and the onions will burn; too cool, and they’ll absorb too much oil and become soggy.
Use paper towels to drain excess oil: This helps maintain the crispiness of the fried onions.
