Let’s Get Cooking!

Step-by-Step Instructions

So, let’s roll up our sleeves and jump into how to make this delightful Air-Fried Onion Boil, shall we?

Prepare the Onion: Start by peeling that glorious onion! Leave the root intact, as it’s going to help hold everything together while cooking. Place it in a bowl and drizzle with olive oil. This will allow the seasonings to stick better.
Season It Up: Add a couple pinches of salt and pepper, cilantro, along with the Old Bay seasoning, smoked paprika, and give it a gentle shake to coat every surface of that onion. Just imagine the smell as you sprinkle those spices!
Air-Fry: Preheat your air fryer to 375°F (190°C). Carefully place the onion into the air fryer basket. Set it to cook for about 20-25 minutes, checking at the 15-minute mark for doneness. You’re looking for that onion to be beautifully tender and slightly caramelized, like the perfect golden hue. You’ll know it’s ready when it’s aromatic and translucent!
Prepare the Garlic Butter Sauce: While the onion is in the air fryer, melt the unsalted butter in a small pan over medium heat. Toss in your minced garlic and cook until fragrant (about 1-2 minutes). Keep an eye on it, as we don’t want it to burn, just a light sizzle will do!
Finish It Off: Once the onion is done, carefully take it out of the air fryer (it’ll be hot!). Drizzle your garlic butter sauce over the onion. Squeeze over some fresh lemon juice if you like (it adds a nice brightness) and garnish with some chopped parsley.
Serve and Enjoy: Slice the onion into wedges and serve it up warm! It can be a side dish or even a meatless main if you pair it with a salad or some crusty bread.

And there you have it! A stunningly simple, yet oh-so-flavorful Air-Fried Onion Boil that’s bound to wow everyone at the dinner table. My kids are always raving about how delicious it is, and guess what? They’re not even huge onion fans!

Serving and Storage Tips

What to Serve With This

Honestly, this Air-Fried Onion Boil pairs beautifully with just about everything! It makes a great side to grilled or baked meats, or you can serve it alongside a fresh salad for a light vegetarian meal.

How Long It Keeps

This dish will keep in the fridge for about 3-4 days. Just make sure it’s stored in an airtight container!

Reheating Instructions

To reheat, pop the onion back in the air fryer for about 5-10 minutes until warmed through, just to crisp it up again. You could also use the microwave, but you lose that delicious crispy exterior!

Is This Freezer Friendly?

I wouldn’t recommend freezing this dish. Onions don’t hold up well in the freezer, and they tend to get mushy when thawed. Enjoy it fresh for the best results!
