# What You Need:

→ Blooming Onion

01 - 1 large sweet onion (such as Vidalia)
02 - 2 1/2 cups all-purpose flour
03 - 2 teaspoons paprika
04 - 1 teaspoon garlic powder
05 - 1 teaspoon dried oregano
06 - 1 teaspoon salt
07 - 1/2 teaspoon ground black pepper
08 - 1/2 teaspoon cayenne pepper
09 - 2 large eggs
10 - 1 cup whole milk
11 - Vegetable oil for frying

→ Creamy Dipping Sauce

12 - 1/2 cup mayonnaise
13 - 2 tablespoons sour cream
14 - 1 tablespoon ketchup
15 - 1 teaspoon prepared horseradish
16 - 1/2 teaspoon smoked paprika
17 - 1/2 teaspoon garlic powder
18 - 1/4 teaspoon cayenne pepper
19 - Salt and black pepper to taste

# Directions:

01 - Whisk together mayonnaise, sour cream, ketchup, horseradish, smoked paprika, garlic powder, cayenne pepper, salt, and black pepper in a small bowl. Cover and refrigerate until serving.
02 - Peel the onion and trim 1/2 inch from the stem end, leaving the root intact. Place cut-side down and make 12 to 16 vertical cuts starting 1/2 inch from the root, being careful not to cut through it. Flip onion and gently separate the petals.
03 - Combine flour, paprika, garlic powder, oregano, salt, black pepper, and cayenne pepper in a large bowl and whisk to blend evenly.
04 - In a separate bowl, beat eggs with whole milk until smooth.
05 - Dredge the onion thoroughly in the flour mixture, ensuring all petals are coated. Shake off any excess.
06 - Submerge the floured onion into the egg mixture, making sure the liquid reaches between all petals.
07 - Return the onion to the flour mixture, pressing lightly to adhere and coating all petals well. Shake off excess flour.
08 - Heat vegetable oil to a depth of at least 3 inches in a deep pot or fryer to 375°F (190°C).
09 - Carefully lower the onion, cut-side down, into the hot oil using a slotted spoon or spider. Fry for 6 to 8 minutes, turning occasionally, until golden brown and crispy.
10 - Remove the onion from oil, drain on paper towels, and season lightly with salt while still hot.
11 - Serve immediately accompanied by the prepared creamy dipping sauce.

# Expert Suggestions:

01 -
  • It looks absolutely impressive when you set it down on the table, and people always underestimate how simple it actually is to make.
  • The contrast between the crispy, golden exterior and the tender onion inside is pure comfort food magic.
  • Your dipping sauce becomes legendary—creamy, tangy, with just enough heat to keep things interesting.
02 -
  • The root must stay intact or the whole thing falls apart—I learned this the hard way on attempt number two.
  • Oil temperature is non-negotiable; too cool and you get a greasy, soggy onion, too hot and the outside burns before the inside cooks through.
  • Don't skip the double-coating step; that's what creates the crispy, golden crust that makes this dish sing.
03 -
  • Use a thermometer for your oil and trust it completely; visual cues will mislead you, but temperature never does.
  • Practice your onion cutting on one before the event if you're nervous—once you understand the motion, it becomes almost meditative and foolproof.
