Step-by-Step Instructions

Here’s how to make a Blooming Onion:

Prepare the Onion:

1. Cut the Onion: Peel the onion and place it root-side down. Using a sharp knife, make four evenly spaced cuts downward, stopping about ½ inch from the root. Make additional cuts in between each section, creating 12-16 petals. Be careful not to cut all the way through.
2. Soak the Onion: Gently separate the layers of the onion and soak it in cold water for 10 minutes. This helps the petals spread apart and makes battering easier.

Prepare the Batter:

3. Mix the Dry Ingredients: In a medium bowl, whisk together the flour, salt, paprika, garlic powder, onion powder, cayenne pepper, and black pepper.
4. Mix the Wet Ingredients: In another bowl, whisk together the buttermilk and eggs until well combined.

Coat the Onion:

5. Dredge in Dry Mixture: Remove the onion from the water and pat it dry. Place it in a large bowl and sprinkle the flour mixture over it, ensuring all petals are coated. Gently shake off excess flour.
6. Dip in Wet Mixture: Carefully dip the onion into the buttermilk mixture, making sure it gets into all the layers. Let any excess drip off.
7. Coat Again: For an extra crispy texture, repeat the process—dredge it in flour again and then dip back into the buttermilk mixture. If using breadcrumbs, sprinkle them over the onion at this stage.

Fry the Onion:

8. Heat the Oil: In a deep, heavy-bottomed pot or deep fryer, heat the vegetable oil to 375°F (190°C). Make sure there’s enough oil to fully submerge the onion.
9. Fry Until Golden: Carefully lower the onion into the hot oil, root side up, using a slotted spoon or tongs. Fry for 3-4 minutes, then carefully flip it over and continue frying for another 3-4 minutes until golden brown and crispy.
10. Drain Excess Oil: Remove the onion from the oil and place it on a paper towel-lined plate to drain excess oil.

Prepare the Dipping Sauce:

11. Mix the Ingredients: In a small bowl, combine mayonnaise, ketchup, Worcestershire sauce, paprika, garlic powder, onion powder, cayenne pepper, horseradish, salt, and pepper. Stir until smooth.
12. Chill: Let the sauce sit for at least 10 minutes to allow the flavors to meld together.

How to Serve Blooming Onion

A Blooming Onion is best served hot and crispy with the dipping sauce on the side. Here are some fun ways to enjoy it:

• As a Party Appetizer: Place in the center of a platter with the sauce for easy dipping.
• With a Burger or Steak: Serve alongside grilled meats for a steakhouse-style meal.
• Game Day Snack: Pair with wings, nachos, and other fun finger foods.
• As a Side Dish: Serve with sandwiches or barbecue for a crispy, flavorful side.

Additional Tips for Blooming Onion

Follow these tips to ensure your Blooming Onion turns out perfect every time:

• Use a Sharp Knife: This makes cutting the onion easier and ensures even “petals.”
• Chill Before Frying: Letting the coated onion rest in the fridge for 10 minutes helps the batter adhere better.
• Maintain Oil Temperature: If the oil is too cool, the onion will absorb too much oil; too hot, and it will burn. Use a thermometer for accuracy.
• Fry in Batches: If making multiple onions, fry one at a time to maintain the oil temperature.
• Use a Slotted Spoon: This helps remove excess batter from the oil and prevents burning.
• Make It Spicier: Add extra cayenne to the batter or sauce for more heat.
