Ingredients

  • Large sweet onion: The sweeter the onion the more flavorful your blooming onion Choose one firm and heavy for its size
  • All purpose flour: This forms the crunchy coating Look for unbleached high quality flour for best results
  • Eggs: Help the coating stick and add extra crunch Fresh eggs work best
  • Paprika: Adds color and depth Use a vibrant fresh paprika for more flavor
  • Garlic powder: Seasons every bite A good garlic powder should smell strong and fresh
  • Salt: Enhances everything Use kosher salt or a flaky variety for an even bite
  • Black pepper: Gives a gentle kick Freshly ground for more flavor
  • Panko breadcrumbs: Extra crispy texture Japanese style panko makes your onion crunchier than regular breadcrumbs
  • Mayonnaise: Creates a creamy dip Go for real mayo
  • Ketchup: Layers in tang and sweetness Choose a good quality ketchup for less sweetness and more real tomato
  • Horseradish: Brings an assertive zing Taste yours first to check its heat level
  • Smoked paprika: Adds mystery and smokiness Opt for real smoked Spanish paprika if you can find it

Instructions

Prepare the Onion:
Carefully cut just the top of the onion off and peel off the skin. Make vertical cuts from the top down but stop before you reach the root so the base holds together. Turn the onion a quarter turn with each cut to create petals. Gently separate the petals so they fan out
Mix the Coatings:
In one shallow bowl combine your flour paprika garlic powder salt and black pepper Mixing well ensures every petal gets properly coated. In another bowl beat the eggs thoroughly for an even coating
Coat the Onion:
Dust the cut and spread onion fully in the seasoned flour mixture making sure to get into each layer. Shake off excess flour. Dip it into the beaten eggs so every petal gets wet. Roll the egg coated onion in panko breadcrumbs pushing crumbs gently into all crevices so it is fully covered
Air Fry the Onion:
Preheat your air fryer to 375 degrees Fahrenheit which ensures crisping from the start. Spray the fryer basket lightly with oil then set the onion cut side up inside. Mist the onion with a little more oil to promote browning. Cook for 12 to 15 minutes until the coating is golden and crunchy and the onion is tender
Make the Bloom Sauce:
In a small bowl stir together mayonnaise ketchup horseradish and smoked paprika until smooth. Taste and adjust horseradish or paprika for extra kick if you like
Serve:
Let your blooming onion cool for 2 minutes before serving with plenty of the dip

This recipe made me fall in love with smoked paprika It transforms both the onion and the sauce adding just enough smoky depth to take it from good to great The first time my dad tried this he asked for the recipe right away and now he makes it for every family BBQ

Storage Tips

An air fryer blooming onion is best right after cooking but if you have leftovers put them in a container lined with paper towels and keep in the fridge for up to three days To re crisp just air fry again for three to five minutes until hot If you want to prep it ahead you can cut and bread the onion a few hours early keep chilled and then pop it into the air fryer when ready

Ingredient Substitutions

If you do not have panko regular breadcrumbs work but will not be quite as crispy For a gluten free version use rice flour and gluten free panko Add a dash of cayenne for extra heat or try chipotle powder for a smoky variation Greek yogurt mixed with a squeeze of lemon is a tangy swap for some of the mayonnaise in the sauce

Serving Suggestions

Serve on a platter with extra bloom sauce on the side for dipping Great with burgers BBQ or movie night Easily doubles for larger crowds You can also tuck smaller blooming onions into individual bowls for a fun dinner party appetizer
