Ingredients You’ll Need

To make these delicious Mini Blooming Onions, you’ll need a few essential ingredients. The buttermilk serves to tenderize the onions while infusing them with flavor, while the flour and spices create a tantalizing crunchy coating. Sweet onions, like Vidalia, contribute their natural sweetness, making for a delightful treat that’s hard to beat.

1 cup Buttermilk (or milk with lemon juice)
1 cup Flour (substitute with gluten-free flour for a gluten-free option)
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
2 medium Sweet Onions (like Vidalia)
as needed Cooking Spray/Oil (for crispy exterior)

How to Make Air Fryer Crispy Mini Blooming Onions

Prepare the Onions: Start by cutting the tops and bottoms off each sweet onion. Slice them into quarters without cutting all the way through, allowing the onion to still hold together. Soak the onions in buttermilk for at least 10 minutes.
Create the Coating: In a mixing bowl, whisk together the flour, paprika, garlic powder, onion powder, cayenne pepper, salt, and pepper until everything is combined. This creates the flavorful coating that adds a wonderful crunch.
Coat the Onions: Remove an onion from the buttermilk and dip it into the seasoned flour mixture, ensuring all exposed areas are evenly covered. Repeat this with the second onion.
Preheat the Air Fryer: Preheat your air fryer to 400°F (200°C) to ensure a hot environment for crisping.
Air Fry the Onions: Lightly spray the basket with cooking spray before placing the coated onions inside. Be careful not to overcrowd; this ensures even cooking. Lightly spray the tops of the onions with cooking oil for an extra crunch.
Cooking Time: Air fry the onions for 12-15 minutes, flipping them halfway through the cooking time, until they are golden and crispy. Keep an eye on them; if they need more time, feel free to add another few minutes.
Check for Doneness: The finished onions should be golden brown and crispy, with a tender interior. A little extra time may be necessary depending on your air fryer.

Tips for Best Results

Ensure the onions are soaked fully in buttermilk; this helps achieve that tender texture inside.
For a smokier flavor, don’t hesitate to use smoked paprika in your coating.
Ensure there’s space between the onions in the air fryer basket; this helps achieve even crispiness.
Flipping halfway is crucial to avoid sogginess on one side; you want that golden look all around.
For an added pop of freshness, serve with a dipping sauce you love, like ranch or spicy mayo.

Variations and Substitutions

Feel free to experiment with different spices based on your flavor preferences. For instance, adding a pinch of cumin or chili powder can introduce even more flavor depth. If you’re looking for a vegan option, almond milk may work in place of buttermilk, but note that it could alter the final taste slightly.

How to Store It
