What Are Blooming Onions?

A blooming onion is an onion that’s cut to resemble a flower, breaded, and deep-fried to crispy perfection. It gets its name from how the slices “bloom” out as it cooks. This version uses small onions, sometimes called boiler onions or baby onions, to make a mini version that cooks beautifully in an air fryer with way less oil.

Ingredients You’ll Need

For the Blooming Onions:

  • 4–6 small onions (about the size of a golf ball)
  • 1 cup all-purpose flour
  • 1 tsp paprika
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • ½ tsp salt
  • ½ tsp black pepper
  • 1–2 eggs (depending on batch size)
  • ¼ cup milk or buttermilk
  • Cooking spray (olive or avocado oil spray works best)

Optional Garnish:

  • Fresh parsley
  • Grated Parmesan
  • Red pepper flakes

For the Dipping Sauce:

  • ½ cup mayonnaise
  • 2 tbsp ketchup
  • 1 tsp prepared horseradish
  • ½ tsp paprika
  • ¼ tsp garlic powder
  • Dash of hot sauce (optional)
  • Salt and pepper to taste

How to Make Baby Blooming Onions in the Air Fryer

Step 1: Prep the Onions

  1. Peel the onions and trim just a little off the bottom (not too much—you want them to stay together).
  2. Place the onion root-side down. Starting about ½ inch from the root, make 4 to 6 cuts downward like you’re slicing a pie—but don’t cut all the way through.
  3. Gently separate the layers to “bloom” the onion. You can soak them in ice water for 30 minutes to help them open up more.

Step 2: Make the Dredge

  1. In one bowl, whisk together the flour, paprika, garlic powder, onion powder, salt, and pepper.
  2. In another bowl, whisk the eggs and milk.

Step 3: Coat the Onions

  1. Dip each onion into the flour mixture, getting it into all the cracks.
  2. Shake off excess, then dip into the egg mixture.
  3. Repeat the flour coating once more for extra crunch.

Step 4: Air Fry

  1. Spray your air fryer basket with oil spray.
  2. Place onions cut-side up, giving each room to cook.
  3. Spray the tops of the onions lightly with oil to help crisp them up.
  4. Air fry at 375°F (190°C) for 15–18 minutes, or until golden and crispy.

Make the Dipping Sauce

While your onions are air-frying, mix together all the dipping sauce ingredients in a small bowl. Taste and adjust seasoning as needed. Chill until ready to serve.

Tips for the Best Blooming Onions

  • Choose the right size onions – Small yellow or white onions work best. You want them about the size of a golf ball.
  • Soak for bloom – A short soak in ice water helps the petals open more.
  • Double dredge for crunch – Flour, egg, flour = crispy perfection.
  • Spray generously – Don’t be shy with the oil spray—it’s what helps the crust get that golden color in the air fryer.
  • Serve immediately – Like all fried goodies, these are best enjoyed hot and fresh!

Fun Variations

Make your Baby Blooming Onions your own:

  • Spicy Kick – Add cayenne pepper or chipotle powder to the flour mix.
  • Cheesy Finish – Sprinkle grated Parmesan over the onions right before the final few minutes of air frying.
  • Herbaceous Twist – Mix in dried Italian herbs or a pinch of rosemary for extra flavor.

How to Serve

These adorable baby blooming onions are super versatile:

  • 🧺 Appetizer platter – Serve with a variety of sauces like ranch, chipotle mayo, or honey mustard.
  • 🍔 Burger night side – A crunchy, fun alternative to fries.
  • 🌽 BBQ pairing – Add to your cookout alongside grilled corn and coleslaw.

Make-Ahead and Storage

Make-Ahead: You can slice and coat the onions up to a few hours ahead. Keep them in the fridge on a parchment-lined tray until ready to air fry.

Storage: Leftovers can be stored in the fridge for up to 2 days, but they’ll lose some crispiness.

To Reheat: Pop them back into the air fryer for 5–6 minutes at 350°F to revive that crunch.
