Ingredients
This recipe makes 4 servings.
For the Bloomin’ Onion:
- 1 large yellow onion (about 1.5 lbs)
- 1 cup all-purpose flour
- ½ cup Panko breadcrumbs
- 1 teaspoon smoked paprika
- 1 teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon cayenne pepper (optional, for a kick)
- 1 teaspoon salt
- ½ teaspoon black pepper
- 2 large eggs
- ½ cup buttermilk (or regular milk with 1 teaspoon lemon juice/vinegar)
- Olive oil spray or avocado oil spray
For the Dipping Sauce:
- ½ cup mayonnaise
- 2 tablespoons ketchup
- 1 tablespoon prepared horseradish (adjust to taste)
- 1 teaspoon Worcestershire sauce
- ½ teaspoon smoked paprika
- ¼ teaspoon cayenne pepper (optional)
- ¼ teaspoon garlic powder
- Pinch of salt and black pepper
Step-by-Step Instructions
-
Step 1: Prepare the Onion
First, peel the outer skin from your large onion. Trim off the very top, but leave the root end intact – this will hold the onion together. Place the onion root-side up on a cutting board.
Small tip: Use a sharp knife for clean cuts.
-
Step 2: Cut the Bloom
Carefully make 12-16 evenly spaced vertical cuts around the onion, starting about ½ inch from the root and cutting all the way through to the cutting board. Do not cut through the root. You want the onion to resemble a blooming flower.
Small tip: A good way to space cuts is to cut into quarters, then each quarter into thirds or fourths.
-
Step 3: Open the Onion
Gently separate the “petals” of the onion with your fingers, working from the outside in. Be careful not to break them off. You want to open it up as much as possible to create space for the coating.
Small tip: Some people like to soak the cut onion in ice water for 15 minutes to help it open up more easily. Pat it very dry afterwards!
-
Step 4: Prepare the Dredging Stations
Set up two shallow bowls. In the first bowl, whisk together the eggs and buttermilk. In the second bowl, combine the flour, Panko breadcrumbs, smoked paprika, garlic powder, onion powder, cayenne pepper (if using), salt, and black pepper. Mix well.
Small tip: Make sure your dry ingredients are thoroughly mixed to ensure even flavor.
-
Step 5: First Coat
Dip the entire bloomed onion into the egg mixture, making sure to get liquid into all the crevices. Lift and let any excess drip off. Then, transfer the onion to the dry mixture bowl.
Small tip: Use one hand for wet ingredients and the other for dry to avoid clumping.
-
Step 6: Second Coat
Generously coat the onion with the flour mixture, gently pressing the crumbs into all the petals. Ensure every part is covered. Gently shake off any excess flour.
Small tip: Really get in there and separate the petals to ensure the coating sticks everywhere.
-
Step 7: Prepare for Air Frying
Lightly spray the coated onion all over with olive oil spray. This helps achieve that beautiful golden-brown crisp. Preheat your air fryer to 375°F (190°C).
Small tip: Don’t skip the oil spray; it’s crucial for crispiness in the air fryer.
-
Step 8: Air Fry the Onion
Carefully place the coated onion into the air fryer basket. You might need to gently flatten it a bit to fit. Air fry for 15 minutes, then open the basket and spray again with oil.
Small tip: Ensure your onion fits without touching the sides too much for even cooking. You may need to cook in batches if your air fryer is small.
-
Step 9: Continue Air Frying
Continue air frying for another 10-15 minutes, or until the onion is tender inside and golden brown and crispy on the outside. Check for doneness by gently prying a petal.
Small tip: Air fryer models vary, so adjust cooking time as needed. Keep an eye on it to prevent burning.
-
Step 10: Make the Dipping Sauce
While the onion is air frying, combine all dipping sauce ingredients in a small bowl. Whisk until smooth and well combined. Taste and adjust seasonings as desired.
Small tip: Make the sauce ahead of time and chill it for flavors to meld beautifully.
-
Step 11: Serve Immediately
Carefully remove the Air Fryer Bloomin’ Onion from the basket. Transfer it to a serving plate and place the dipping sauce in the center or alongside. Serve warm and enjoy!
Small tip: This dish is best enjoyed fresh for maximum crispiness.
Tips & Variations
- Gluten-Free Option: Simply swap the all-purpose flour for a gluten-free all-purpose flour blend (one designed for baking/frying) and use gluten-free Panko breadcrumbs.
- Vegan/Vegetarian Option: For a vegan version, use a plant-based milk for the wet dredge and a flax egg (1 tablespoon ground flaxseed + 3 tablespoons water per egg) or a commercial egg replacer. Omit buttermilk and use a plant-based milk with a splash of apple cider vinegar instead. Ensure your mayonnaise is vegan.
- Add More Flavor or Protein: For an extra cheesy kick, sprinkle some grated Parmesan cheese into the dry flour mixture. You could also serve it alongside some grilled chicken strips or baked tofu for a more complete meal.
- Spicy Version: Amp up the heat by doubling the cayenne pepper in both the dry coating and the dipping sauce. A dash of hot sauce in the dipping sauce also works wonders!
- Herbaceous Twist: Add 1 teaspoon of dried Italian herbs or dried thyme to the dry flour mixture for a fragrant, savory variation. Fresh chopped chives or parsley make a lovely garnish too.
