  • 1 tsp smoked paprika

Method
 

Prepare the Onions:
  1. Cut one end off of each onion and peel the outside layer.
  2. Slice the onions into ½inch thick rings.
  3. Separate each ring and place them in a Ziplock bag.
Marinate:
  1. In a bowl, whisk together the buttermilk, sour cream, salt, black pepper, garlic powder, onion powder, smoked paprika, and cayenne (if using).
  2. Pour the marinade over the onions in the Ziplock bag. Add ¼ cup of water to the bowl to use up the rest of the marinade, then pour this into the bag as well.
  3. Seal the bag and place it in the refrigerator for at least 1 hour, preferably overnight.
Heat the Oil:
  1. Heat the oil in a deep fryer or a large pot to 375°F.
Prepare the Dredge:
  1. In a 9x9 dish, whisk together the flour, cornstarch, salt, black pepper, garlic powder, onion powder, smoked paprika, and cayenne (if using).
Fry the Onion Rings:
  1. Remove the marinated onions from the refrigerator.
  2. Take out ¼ of the onion rings and toss them in the dredge mixture until each ring is well coated. Shake off any excess flour.
  3. Carefully place the coated onion rings into the hot oil. Fry for 2-3 minutes or until golden brown.
  4. Remove the onion rings from the oil and place them on a cooling rack. Immediately sprinkle with salt.
  5. Repeat the process until all the onion rings are fried.
Serve:
  1. Enjoy the onion rings with ranch dressing or your favorite dipping sauce.
Tips
  1. Marinating the onions overnight will yield the best results, as it softens the onions and reduces their sharpness.
  2. Ensure the oil is at the correct temperature for optimal crispiness.
  3. Use a cooling rack instead of paper towels to keep the onion rings crispy.
