Air Fryer BLOOMING ONION Appetizer Recipe
My family loves a good crispy Blooming Onion, but the deep-fried version is SO unhealthy! I decided to make this healthier alternative with a horseradish based sauce! This is the perfect appetizer for get-togethers, game days, or when you are craving a crunchy treat.
Making this recipe may seem like an intimidating task, but I promise this air fryer blooming onion recipe is so simple! I’ve included step-by-step instructions below with pictures to guide you. You’ll find the full recipe and instructions at the bottom of this post in the recipe card.
Ingredients You’ll Need:
onion- For this recipe, you will need a large sweet Vidalia onion.
all-purpose flour- You can’t make a crispy batter without flour.
paprika and cayenne pepper- These spices will add a slight kick to the batter.
ground cumin, dried thyme, and oregano- They add an earthy flavor to the batter.
eggs, water, and milk- This helps the flour adhere to the onion, and leaves the onion golden when it is finished.
cooking oil- You will need to spray this on your onion so that it gets crispy in the air fryer.
Sauce
mayo- Acts as a stabilizer to keep the sauce combined.
sour cream- Adds a tangy flavor to the horseradish sauce.
ketchup- Provides a little sweetness to counteract the spice of the horseradish, and gives the sauce its signature color.
horseradish- Makes the sauce slightly spicy, while adding a distinct tasty flavor.
paprika, salt, garlic powder, and dried oregano- These spices take it over the top!
How to cook an Air Fried Blooming Onion:
Step 1: Combine mayo, sour cream, ketchup, horseradish, and spices into a bowl, and place in the refrigerator.
Step 2: Gather the rest of the ingredients. Begin to slice the onion to make it into a bloom. Start by cutting 1/2 inch from the top of the onion, then peel the outer skin from the onion. The top of the onion resembles a stem, while the bottom has small brown roots sprouting out of it.
Next, place the onion cut-side down.
Step 3: Starting about 1/2 inch from the root, make a downward cut through to the cutting board. Make sure that you don’t cut too close to the top of the onion because the onion will end up falling apart when you are breading it. Repeat to make 4 evenly spaced cuts around the onion.
Step 4: Make 3 additional cuts between each section until you have 16 evenly spaced cuts. If cutting the onion into a bloom seems a little too tricky, you can also purchase a blooming onion cutter
Step 5: Turn the onion over and allow it to rest for 5 minutes so that the petals begin to relax.
Step 6: Allow the onion petals to relax so that they begin to spread out a bit to make it easier to add the flour and spices.
Step 7: Combine the flour and spices in a bowl.
Step 8: In another bowl, whisk together eggs, milk, and water. Transfer the onion into a new bowl, cut-side up, and pour the flour mixture over the top. Use a large spoon coat the onion with the flour mixture, especially between the onion petals. Turn the onion over and pat off the excess flour. Reserve the flour. You will need it later.
Make sure there are no large clumps of flour left on the onion because this will lead to parts of the onion being doughy and undercooked.
