Ingredients
Veggies
- 2 medium Sweet Onions (like Vidalia)
Batter & Coating
- 1 cup Buttermilk (or milk with lemon juice)
- 1 cup Flour (substitute with gluten-free flour for a gluten-free option)
Spices
- 1 tbsp Paprika (consider using smoked paprika for extra flavor)
- 1 tsp Garlic Powder
- 1 tsp Onion Powder
- 0.5 tsp Cayenne Pepper (adjust according to taste)
- 1 tsp Salt
- 1 tsp Pepper
Finishing
- as needed Cooking Spray/Oil for a crispy exterior
Instructions
Preparation
- Trim the top and root end of the onions so they can sit flat, then slice 8–10 cuts from the top toward the root to create a bloom, keeping the root intact.
- Pour buttermilk into a bowl and soak the cut onions for 10 minutes to help the coating stick and mellow the onion.
Batter Preparation
- Whisk flour, paprika, garlic powder, onion powder, cayenne, salt, and pepper in a shallow bowl.
Dredging
- Shake excess buttermilk off each onion, then dredge inside and out in the flour mixture so each petal is coated.
Air Frying
- Preheat the air fryer to 375°F. Place onions petal-side up in the basket, spray lightly with cooking spray, and air fry for 10–12 minutes until golden.
- Flip carefully if needed and crisp for another 2–4 minutes for even color and texture. Remove and let rest for 2 minutes before serving.
Notes
Keep the root intact while slicing so the petals stay connected during cooking. Don’t overcrowd the air fryer; give each onion room for hot air to circulate for even crisping. Lightly spray the coated onion with oil for a golden finish without deep frying. Adjust cayenne to your heat preference and taste the dry mix before dredging. Re-crisp leftovers in the air fryer at 350°F for 3–5 minutes instead of microwaving.
