Firecracker Blooming Onion


  •  3 Walla Walla Sweet Onions
  • 2 eggs
  • 1 cup milk
  • 1 cup flour
  • 1 tbsp paprika
  • 1 tbsp cumin
  • 1 tsp dried oregano
  • 1 tsp thyme
  • 1 tsp salt
  • 1 tsp ground cayenne pepper
  • ½ tsp ground black pepper
  • Vegetable oil

Dipping sauce

  • ¼ cup mayonnaise
  • ¼ cup sour cream
  • 1 ½ tbsp creamy horseradish
  • 1 ½ tbsp ketchup
  • ½ tsp paprika
  • ½ tsp garlic powder
  • ¼ tsp ground cayenne pepper

Prep time: 20 minutes
Cook time: 18 minutes
Servings: 3


  1. Combine the dipping sauce ingredients and set aside.
  2. Whisk egg and milk in a bowl big enough to fit the onion.
  3. In a separate bowl that’s also big enough to fit the onion, combine flour, paprika, cumin, dried oregano, thyme, salt, cayenne pepper, black pepper, and garlic powder.
  4. Cut a small flat spot on the bottom of the onion. Place the onion flat side down (root side up). Using a sharp knife starting about ½ inch from the root, make a clean slice downward. Turn the onion one quarter and make another clean slice downward. Repeat the quarter turn two more times so your onion is cleanly sliced in four quarter sections. Then cut three to four equal spaced cuts downward in each section. Then, turn the onion over and gently fan out the sections.
  5. Put the onion in the flour mixture bowl. Coat the onion with the flour mixture. Make sure that all of the onion gets breaded. Then dunk the onion into the egg mixture. Afterwards, put it back into the flour mixture bowl and coat the onion again.
  6. Heat oil in a heavy pan to 375 degrees. Fry the onion root side up for 5-7 minutes. Drain on paper towels.
  7. Serve with the dipping sauce mixture and enjoy!

1. Heat a couple of inches of oil in a deep, heavy pot to 300° F.

4. In a bowl, whisk together mayonnaise, ketchup, relish, sugar, and vinegar. Set aside.
5. Remove fries from water and place on paper towels, blotting to dry.
6. In 3 to 4 batches, cook the fries for 4–5 minutes per batch until soft, not browned. Using a slotted spoon, remove each batch of fries from the oil and drain on paper towels.
7. Increase the temperature of the oil to 400° F. Cook the fries in batches again until they are golden brown. Remove from the oil and drain on paper towels. Sprinkle with salt.
8. Place some freshly cooked fries on a plate and cover with an American cheese slice. Top with fry sauce and caramelized sweet onions and serve alongside your favorite burger. Enjoy!Tip: We also topped our favorite burger with the extra caramelized sweet onions and fry sauce…so delicious!
