1 large sweet onion
1/2 cup ranch dressing of choice
1/2 cup milk
1 cup all-purpose flour
1 teaspoon salt or to taste
1 teaspoon black pepper or to taste
1/4 teaspoon cayenne pepper
2 cups vegetable oil
Recipe
Slice onion into thinnest possible rings. Place in a shallow dish. Pour ranch dressing and milk over onions, cover and refrigerate at least 1 hour.
In a plastic bag, combine flour, salt, black pepper and cayenne pepper. Shake to evenly distribute ingredients.
Heat oil to 375 degrees F in deep saucepan or deep fryer. Remove a small handful of onion rings from dressing and shake off excess. Drop into flour, separate rings and shake to coat.
Drop a few rings at a time into hot oil and cook until golden. Remove from hot oil with a slotted spoon and drain on a paper towel. Repeat with remaining rings until all rings have been battered and fried. Keep warm.
