Ingredients You’ll Need for Air Fryer Crispy Mini Blooming Onions for Guilt-Free Snacking
- 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)
- Cooking Spray/Oil (for crispy exterior)
Let’s Make It Together
-
Prep the Onions: Start by peeling the sweet onions. Cut off the tops and bottoms, and then slice each onion into quarters from the top to about half an inch above the bottom, being careful not to cut completely through. Gently separate the petals to create the blooming effect.
-
Soak in Buttermilk: In a mixing bowl, pour the buttermilk (or milk with lemon juice) over the prepared onions, allowing them to soak for at least 30 minutes. This step makes your blooming onions tender and flavorful.
-
Make the Flour Mixture: In another bowl, combine the flour, paprika, garlic powder, onion powder, cayenne pepper, salt, and pepper. Mix well to ensure all spices are evenly distributed.
-
Coat the Onions: After soaking, remove the onions from the buttermilk and allow excess liquid to drip off. Carefully dredge each onion into the flour mixture, ensuring each petal is coated well. Gently shake off any excess flour.
-
Prepare the Air Fryer: Preheat your air fryer to 380°F (193°C) for about 5 minutes. Spray the basket lightly with cooking spray or oil to help achieve that golden brown finish.
-
Air Fry the Onions: Place the coated onions into the air fryer basket, leaving space between each one. Spray the tops with cooking spray or oil for added crispiness. Air fry for 10-12 minutes, flipping halfway through, until they are golden and crispy.
-
Serve Warm: Once the onions are done, carefully remove them from the air fryer and let them cool for a moment. Serve warm with your favorite dipping sauce!
Delicious Variations to Try
- Zesty Lemon Twist: Add a splash of lemon juice to your buttermilk for a refreshing zesty flavor that brightens every bite.
- BBQ Bliss: Sprinkle a bit of barbecue seasoning into the flour mixture for an added smoky and sweet taste that’s perfect for summer snacking.
- Cheesy Delight: Sprinkle grated Parmesan cheese over the onions before air frying for a rich, cheesy crust that will deepen the flavors.
- Spicy Kick: Increase the cayenne pepper or add a dash of hot sauce to the buttermilk for an extra spicy twist that will send your taste buds dancing!
Chef Emma’s Helpful Tips
- Make Ahead: You can prepare the onions, coat them in the flour mixture, and refrigerate until you’re ready to cook them. Just add a few extra minutes to the cooking time if they’re chilled.
- Slicing Technique: For a consistent bloom, use a sharp knife to slice the onions—this helps them cook evenly and creates beautiful petals.
- Storage Suggestions: Cooked blooming onions can be stored in an airtight container in the fridge for up to 3 days. To re-crisp, pop them in the air fryer for a few minutes at 380°F (193°C).
- Try Different Onions: While sweet onions are fantastic, you can experiment with red onions for a bolder flavor or yellow onions for a classic taste.
