Air Fryer Bloomin' Onion

Instructions

1. Step 1

   Gather the ingredients.

2. Step 2

   In a small bowl, combine the mayonnaise, ketchup, horseradish, garlic powder, paprika, oregano, salt, black pepper, and cayenne pepper. Stir to blend. Cover and refrigerate until serving time.

3. Step 3

   Cut the top off the onion and remove the outer peel.

4. Step 4

   Place the onion on a cutting board, cut-side down. With a sharp knife, make a cut about 1/2-inch from the root.

5. Step 5

   Make three more evenly spaced cuts around the onion. You will have 4 evenly spaced portions. Make sure you leave the root intact.

6. Step 6

   Make 2 to 3 cuts in the center of each quarter. You should have 12 to 16 cuts, depending on the size of the onion.

7. Step 7

   Turn the onion over and separate the petals slightly.

8. Step 8

   Place the onion in a bowl of ice water and let stand for 1 to 2 hours. Remove the onion to paper towels to drain. 

9. Step 9

   Place the onion in a bowl and sift the flour over it while gently separating the petals. You might have to do this a few times to get good coverage. Gently turn the onion upside-down to shake off any excess.

10. Step 10

    In a bowl, whisk the eggs with the buttermilk. Place the onion in a bowl and pour the egg mixture over it, gently separating the petals. Remove the onion to a wide, shallow bowl.

11. Step 11

    Combine the breadcrumbs and Old Bay seasoning; sprinkle over the onion petals.

12. Step 12

    Set the air fryer temperature to 375 F and preheat the following the manufacturer's directions. Spray the tray with cooking oil spray and add the onion, root-side down. Cook for 15 minutes. 

13. Step 13

    Serve the blooming onion immediately with the dip.
