There’s something undeniably fun about a blooming onion—the crispy petals, the savory seasoning, the way it’s meant to be shared (though no judgment if you keep it all to yourself).

Whether you’re hosting a party, craving a snacky dinner (we’ve all been there), or just want to impress your family with your culinary flair, this recipe is a winner. Plus, it’s a sneaky way to make veggies the star of the show!

How to Make an Air Fryer Blooming Onion

Don’t let the fancy look fool you—this recipe is simpler than it seems. Here’s how to nail it:

Ingredients You’ll Need

• 1 large sweet onion (like Vidalia)
• 1/2 cup all-purpose flour
• 1 tsp paprika
• 1 tsp garlic powder
• 1/2 tsp cayenne pepper (adjust to taste)
• 1/2 cup buttermilk (or milk + 1 tsp vinegar)
• Cooking spray or olive oil
• Salt to taste

Step-by-Step Instructions

1. Prep the onion: Cut off the top (not the root end!), peel it, then make vertical cuts to create petals. Gently spread them open.
2. Dredge: Dip the onion in buttermilk, then coat evenly with the flour-spice mixture.
3. Air fry: Spray the onion with oil, place it in the air fryer basket, and cook at 375°F for 12–15 minutes until golden.
4. Serve: Sprinkle with salt and dig in while it’s hot!

Tips for the Perfect Blooming Onion

• Use a sharp knife and a steady hand for even petals.
• If the flour isn’t sticking, dip the onion in buttermilk again before coating.
• For extra crispiness, spritz the petals lightly with oil before air frying.
• Pair it with other air fryer favorites like crispy chicken wings for a full spread.

There you have it—a blooming onion that’s as fun to make as it is to eat. Whether you’re serving it up for a party or just because you deserve something crispy and delicious, this air fryer version is sure to impress.

Instructions

1. Prepare the Crust:

1. 1. Prepare the onion: Peel the onion and cut about 1/2 inch off the top. Leave the root end intact.
2. 2. Turn the onion upside down (root side up). Make 4 vertical cuts downward, dividing the onion into quarters, but stop about 1/2 inch from the root to keep it intact.
3. 3. Make 3-4 more cuts between each quarter to create 16-20 ‘petals.’ Gently separate the layers.
4. 4. Soak the onion in buttermilk for at least 30 minutes (or up to 2 hours) to tenderize and help the coating stick.
5. 5. Preheat the air fryer to 375°F (190°C).
6. 6. In a bowl, mix flour, paprika, garlic powder, onion powder, cayenne, salt, and black pepper.
7. 7. Remove the onion from buttermilk, letting excess drip off. Dredge in the flour mixture, ensuring all layers are coated. Shake off excess.
8. 8. Spray the air fryer basket with oil. Place the onion root-side down in the basket. Lightly spray the onion with oil.
9. 9. Air fry for 12-15 minutes until golden and crispy. Check halfway and respray if needed.
10. 10. Make the dipping sauce: Mix mayonnaise, ketchup, horseradish, paprika, garlic powder, and salt in a small bowl.
11. 11. Serve the blooming onion hot with the dipping sauce.

Notes

For extra crispiness, double-dip the onion in buttermilk and flour mixture. If petals stick together during cooking, gently separate them with tongs. Adjust cayenne for desired spiciness.
