Crispy Mini Bloomin Onions (Printable)

Miniature blooming onions with a crunchy golden crust and creamy horseradish dipping sauce—a crowd-pleasing appetizer.

# What You’ll Need:

→ Vegetables

01 - 6 small sweet onions (pearl or cipollini, 2–3 inches in diameter)

→ Breading

02 - 1 cup all-purpose flour
03 - ½ cup cornstarch
04 - 1 teaspoon smoked paprika
05 - 1 teaspoon garlic powder
06 - 1 teaspoon onion powder
07 - ½ teaspoon salt
08 - ¼ teaspoon black pepper
09 - ¼ teaspoon cayenne pepper (optional, for heat)

→ Wet Batter

10 - 2 large eggs
11 - ½ cup whole milk

→ Frying

12 - 1 quart vegetable oil (for deep frying)

→ Dipping Sauce

13 - ½ cup mayonnaise
14 - 2 tablespoons ketchup
15 - 1 tablespoon prepared horseradish
16 - ½ teaspoon smoked paprika
17 - ½ teaspoon garlic powder
18 - ½ teaspoon lemon juice
19 - Pinch of salt

# How-To Steps:

01 - Trim the root end just enough so each onion stands upright without falling apart, then peel. Make 4 to 6 vertical cuts from top to root, stopping about ¼-inch from the base to keep layers connected. Rotate and add additional cuts to form 8 to 12 petals, then gently separate them with your fingers.
02 - Combine all dry breading ingredients — flour, cornstarch, smoked paprika, garlic powder, onion powder, salt, black pepper, and cayenne — in a shallow bowl. In a second bowl, whisk together the eggs and whole milk until uniform.
03 - Dip each scored onion into the flour mixture, ensuring all surfaces and petals are well coated. Shake off excess flour, submerge in the egg-milk wash, then return to the flour mixture. Press gently to adhere the coating to every petal.
04 - Pour vegetable oil into a deep pot or fryer and bring to 350°F over medium-high heat. Use a thermometer to maintain consistent temperature throughout frying.
05 - Lower one or two onions into the oil cut side down. Fry for 2 to 3 minutes until golden, then flip and continue frying for another 2 to 3 minutes until crisp and cooked through. Adjust heat as needed to keep oil at 350°F.
06 - Lift the fried onions out with a slotted spoon and transfer to a paper towel–lined surface to drain. Sprinkle with additional salt while still hot if desired.
07 - Combine mayonnaise, ketchup, prepared horseradish, smoked paprika, garlic powder, lemon juice, and a pinch of salt in a bowl. Stir until fully incorporated and smooth.
08 - Arrange the hot mini bloomin onions on a serving plate alongside the dipping sauce. For variety, offer ranch dressing or spicy aioli as additional options.

# Expert Tips:

01 -
  • The double-dredge method creates a shatter-crisp shell that holds up long past the first dip
  • Mini size means faster frying and no wrestling with a giant onion on a skewer
02 -
  • Cutting too close to the root will cause the onion to fall apart entirely during frying, and there is no way to fix that once it happens
  • Cornstarch in the breading is what separates these from a soggy flour-only coating, and skipping it was the mistake that taught me this lesson
03 -
  • Let the floured onions rest for 5 minutes before the egg wash so the starches hydrate slightly and form a tighter seal around each petal
  • A pinch of baking powder in the flour mix adds microscopic air bubbles that make the crust even lighter and more shatter-crisp
