Begin by heating vegetable oil in a deep fryer or a large pot, bringing it to 350°F (175°C).

In a medium bowl, whisk together the all-purpose flour, garlic powder, paprika, salt, and black pepper until well combined.

Pour buttermilk into a separate shallow bowl, creating a dipping station for your onion rings.

Take each onion ring and dip it into the buttermilk, then transfer it to the flour mixture, coating thoroughly.

For extra crunch, return the coated onion ring to the buttermilk, then dredge it in panko breadcrumbs.

Carefully place a few coated onion rings into the hot oil in batches, frying for 2-3 minutes until golden brown.

Using a slotted spoon, remove the fried onion rings from the oil and place them on paper towels to drain excess oil.

Serve warm with your favorite dipping sauces and enjoy!
