Crispy fried onions are a beloved snack, topping, and flavor enhancer that can elevate countless dishes. Whether you're a fan of classic comfort food or love experimenting with Asian flavors, crispy fried onions bring that satisfying crunch and umami flavor to any plate. In this guide, we’ll explore three varieties of crispy fried onions: vegan-friendly versions, Asian-inspired crispy onions, and the timeless classic fried onions. Let’s dive in and learn how to make these delicious treats from scratch!

1. Crispy Fried Onions (Vegan Edition)

Gone are the days when crispy fried onions were strictly for non-vegans. Now, with just a few simple tweaks, you can enjoy all the crispy goodness without any animal products! Vegan crispy fried onions are perfect for adding a plant-based crunch to dishes like salads, burgers, casseroles, and even vegan sandwiches.

How to Make Vegan Crispy Fried Onions:

To make these crispy fried onions vegan, you’ll need:

  • 1 large onion, thinly sliced
  • 1 cup of plant-based milk (like almond or oat milk)
  • 1 cup of all-purpose flour
  • 1/2 cup of cornstarch (for extra crispiness)
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon smoked paprika (optional, for a smoky kick)
  • Salt and pepper to taste
  • Vegetable oil for frying

Instructions:

  1. Prep the Onions: Slice the onion into thin rings or strips. Soak them in a bowl of plant-based milk for at least 30 minutes. This helps the batter stick better and softens the onions.
  2. Prepare the Batter: In a separate bowl, whisk together the flour, cornstarch, garlic powder, onion powder, smoked paprika, salt, and pepper.
  3. Coat the Onions: Drain the onions and dip them into the flour mixture, ensuring each piece is well coated.
  4. Fry the Onions: Heat vegetable oil in a deep pan over medium-high heat. Once the oil is hot, fry the onions in batches until golden brown and crispy—usually about 2-3 minutes per batch.
  5. Drain and Serve: Remove the fried onions from the oil and place them on paper towels to drain excess oil. Serve them hot and crispy on top of your favorite dish.

These vegan crispy fried onions are perfect for adding a savory, crunchy bite to your vegan burgers, soups, or a vegan green bean casserole. They’re the ideal snack or topping for any occasion.

2. Fried Onions with an Asian Twist

If you're craving something with a little more flair, Asian-style crispy fried onions are a fantastic way to elevate your dishes with bold flavors and textures. In Asian cuisine, fried onions are often paired with soy sauce, sesame oil, and chili for an extra burst of savory and spicy goodness.

How to Make Asian-Inspired Fried Onions:

For this recipe, you’ll need:

  • 1 large onion, thinly sliced
  • 1/2 cup of rice flour (or regular flour)
  • 2 tablespoons cornstarch
  • 2 tablespoons soy sauce (for a salty umami flavor)
  • 1 tablespoon sesame oil (for a nutty aroma)
  • 1/2 teaspoon chili flakes (optional, for a spicy kick)
  • 1/4 teaspoon ground ginger (for extra depth of flavor)
  • Vegetable oil for frying

Instructions:

  1. Prep the Onions: Slice the onions into thin rings. To add more flavor, soak the onions in a mixture of soy sauce and sesame oil for 15-20 minutes before frying.
  2. Make the Coating: In a bowl, mix together rice flour, cornstarch, chili flakes, and ground ginger.
  3. Coat the Onions: Once the onions are soaked, drain them and toss them in the flour mixture until they're evenly coated.
  4. Fry to Perfection: Heat oil in a wok or deep pan over medium-high heat. Fry the onions in small batches until they’re golden and crispy.
  5. Drain and Serve: Once fried, drain the onions on paper towels to remove excess oil. Serve them on top of your favorite Asian dishes like noodle bowls, stir-fries, or even crispy fried rice.

These Asian-style crispy onions add a flavorful, crunchy garnish that complements savory Asian dishes beautifully. Their smoky, salty, and spicy notes take your meals to the next level!
