Step‑by‑Step Instructions for Air Fryer Crispy Mini Blooming Onions
Step 1: Prepare Buttermilk
In a mixing bowl, combine buttermilk or milk with lemon juice, letting it sit for 5 minutes. This thickening process is essential for ensuring the coating adheres well to the onions, setting the stage for those delightful Air Fryer Crispy Mini Blooming Onions.
Step 2: Prep Onions
Start by carefully peeling the sweet onions, such as Vidalia. Trim the tops and bottoms to create a stable base. Then, make vertical cuts from the top to about an inch from the bottom, creating petal-like shapes. This will allow the onions to bloom beautifully during cooking, enhancing their presentation.
Step 3: Combine Coating
In a separate bowl, mix the flour, paprika, garlic powder, onion powder, cayenne pepper, salt, and pepper. Whisk the ingredients together until fully combined, creating a flavorful coating that will elevate your Air Fryer Crispy Mini Blooming Onions. Ensure the mixture is well-blended to achieve an even taste.
Step 4: Coat Onions
Dip each blooming onion into the prepared buttermilk, ensuring it is evenly coated while shaking off any excess. Then, carefully dredge the onion in the flour mixture, covering all surfaces thoroughly. This step is crucial for achieving that crispy texture, so take your time to coat them evenly.
Step 5: Preheat Air Fryer
Set your air fryer to 380°F (190°C) and let it preheat for about 5 minutes. This step ensures that the Air Fryer Crispy Mini Blooming Onions cook evenly and achieve that perfect golden-brown color. A hot air fryer will make all the difference in achieving that delightful crunch.
Step 6: Arrange in Air Fryer
Place the coated onions in the air fryer basket, ensuring they have enough space for air circulation. This will help them crisp up nicely. Lightly spray the tops of the onions with cooking spray or oil to enhance browning. Avoid overcrowding the basket for optimal results.
Step 7: Air Fry
Cook the onions in the air fryer for 10-12 minutes, shaking the basket halfway through. This is important for even cooking and crispiness. As the onions cook, they will begin to bloom, and you’ll notice that delightful golden color developing—a sure sign they are becoming the perfect Air Fryer Crispy Mini Blooming Onions.
Step 8: Prepare Dipping Sauce
While the onions are air frying, mix together mayonnaise, ketchup, horseradish, lemon juice, and any seasonings to create a delicious dipping sauce. This will complement your Air Fryer Crispy Mini Blooming Onions perfectly, adding a zesty touch to your appetizer.
Step 9: Serve
Once the onions are crisp and golden brown, carefully remove them from the air fryer. Serve them warm alongside your homemade dipping sauce. Optionally, garnish with fresh herbs for an extra flair. Your guests will be thrilled to savor these Air Fryer Crispy Mini Blooming Onions!

Air Fryer Crispy Mini Blooming Onions Recipe FAQs
How do I choose the right onions for this recipe?
When selecting onions, I absolutely recommend using sweet onions like Vidalia or Walla Walla! Look for ones that are firm and have a smooth skin without dark spots. They should feel heavy for their size and have a strong aromatic scent. This ensures that they’ll bloom beautifully and carry that delightful sweetness you want in your Air Fryer Crispy Mini Blooming Onions.
How should I store leftover Air Fryer Crispy Mini Blooming Onions?
Store your leftover crispy onions in an airtight container in the refrigerator for up to 2 days. It’s key to make sure they are sealed tightly to maintain their crunch. When reheating, pop them back into the air fryer at 350°F (175°C) for about 5-7 minutes for a perfect re-crisp.
Can I freeze uncooked Air Fryer Crispy Mini Blooming Onions?
Yes, you can freeze them! After breading, lay the uncooked mini blooming onions on a baking sheet in a single layer and freeze for about 1 hour until solid. Then, transfer them to an airtight bag or container and store for up to 1 month. When you’re ready to enjoy, cook them from frozen in the air fryer, just adding a couple of extra minutes to the cooking time.
What if the coating doesn’t stick to my onions?
If you find that the coating isn’t adhering well, don’t worry! Simply dip the onions back into the buttermilk, allowing any excess to drip off, and then re-coat them in the flour mixture. This double-dipping technique helps create a thicker, crunchier crust when air-fried.
Are Air Fryer Crispy Mini Blooming Onions safe for pets?
It’s essential to keep these delicious treats away from pets. Onions are toxic to dogs and cats, leading to serious health issues. Make sure to properly dispose of any scraps and educate your guests to avoid sharing these with their furry friends!
