# What You Need:

→ Blooming Onion

01 - 1 large sweet onion (Vidalia preferred)
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 deep frying, sufficient to fill 3 inches in pot

→ 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

# Step-by-step guide:

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 onion and trim 1/2 inch off the top, leaving root intact. Place cut-side down and slice downward all around starting 1/2 inch from the root creating 12 to 16 petals without cutting through root. Turn onion over and gently separate petals.
03 - Combine flour, paprika, garlic powder, oregano, salt, black pepper, and cayenne pepper in a large bowl and whisk thoroughly.
04 - In a separate bowl, beat eggs with whole milk until blended.
05 - Dredge the onion in the seasoned flour, ensuring thorough coating between all petals. Shake off excess flour.
06 - Submerge the floured onion into the egg mixture, making sure the liquid reaches between all petals.
07 - Coat the onion again in the flour blend, pressing lightly for adherence. Shake off any surplus flour.
08 - Heat vegetable oil at least 3 inches deep in a heavy pot or fryer to 375°F (190°C).
09 - Using a slotted spoon or spider, carefully lower cut-side down into hot oil. Fry for 6 to 8 minutes, turning occasionally until golden brown and crisp.
10 - Remove the onion and drain on paper towels. Lightly season with salt while hot.
11 - Serve immediately accompanied by the prepared creamy dipping sauce.

# Expert Tips:

01 -
  • It looks impossibly fancy but is genuinely achievable at home, making you feel like a culinary genius without the stress.
  • The contrast of crispy exterior and tender, sweet onion layers is addictive in ways you won't expect.
  • That dipping sauce hits differently than restaurant versions because you control every element of the flavor.
02 -
  • Oil temperature is everything here; if it's too cool the onion absorbs oil and tastes greasy, and if it's too hot the outside burns before the inside cooks through, so invest in a thermometer and use it.
  • Don't skip the double coating or you'll end up with patches where the onion shows through; the double coverage is what creates that crispy, professional-looking exterior.
03 -
  • A blooming onion cutter tool exists and genuinely does make the slicing easier, but a sharp chef's knife and some patience works just as well.
  • Keep your oil thermometer clipped to the pot during frying so you can monitor temperature and adjust heat as you go; nobody talks about this but it's the difference between restaurant results and home kitchen attempts.
