🍳 How to Make a Blooming Onion
How to Cut a Blooming Onion
Step One: Peel off the outer skin of the and cut the stem off on a cutting board.
Step Two: Flip to the cut side down, and then make four cuts through the center of the onion, stopping about ½ inch from the root. You do not want to cut all the way through.
Step Three: Then make more cuts to segment into eighths as showing in the photos to make the petals.
PRO TIP: If you have time, soak the onion in cold water for 2 hours to allow the petals to gently fall.

Step Four: Add the egg and milk to a clean bowl and whisk together. In another bowl add the all purpose flour and spices.
Step Five: Dredge the cut onion in the milk and egg mixture and allow excess dry to fall off followed by the flour mixture. Shake off excess flour. Repeat the process to create a breaded coating.
Step Six: Place your onion in the air fryer basket, and spritz with oil with the stem end on the bottom of the basket. Cook at 350 degrees for nine minutes or until it is golden brown.
Full directions and measurements for the recipe are in the printable recipe card below.
🍴 Storing Leftovers
Store leftovers in an air tight container. Wrap the leftovers in paper towels on all sides to capture the excess oil and help it not get mushy while in the refrigerator.
✨ How to Reheat
Air Fryer | Heat up the fryer to 400 degrees. Lightly spray the leftover blossom with olive oil and place in the fryer for 4-5 minutes to heat and crisp back up.
Oven | Heat up the oven to 350 degrees. Place the leftovers on a wire rack pan on a sheet pan. Cook for 8-10 minutes and broil for 1-3 minutes to make extra crispy at the end.
We don’t recommend using the microwave as the exterior coating will be soft and not crispy like you would like.
🥄 Meal Prep
Fortunately, meal prepping this for game days and parties will save so much time for these.
Cut the onion and prep the dipping bowls the morning or night before. Choose the option of soaking the onion in cold water or buttermilk to have the petals splay open more and allow the coating to stick even better.
📌 Expert Tips
- Play around with the seasoning and spices to create the flavor combinations you like.
- If you own an Ninja Foodi or Instant Pot Duo Crisp I share how to use them to make this in the recipe card below.
- Make more than one, just cook them one at a time, or leave room between each so it doesn’t touch. You need good air flow for this to cook evenly.
- Make sure to not cut all the way through, you want to keep the bottom of onion cut side intact so it holds together as it air fries.
- If you are struggling stopping the cuts at the ½” mark, place two wooden spoons on the counter and cut through the onion until you hit the spoons. This allows you to make even cuts without accidentally slicing all the way through!
- Double dipping the batter will allow for a crispier coating.
- If you are worried about the onion falling apart, make an aluminum foil sling to put UNDERNEATH of the onion before cooking. To make a sling, cut a piece of foil long enough to go from ONE SIDE of the air fryer basket DOWN TO COVER the bottom of the basket and then UP THE OPPOSITE SIDE OF THE BASKET. The two opposite sides will be the handles to pull it out of the basket when it is finished cooking.
- Use a spoon to get the coating in between all the petals if they are not all the way coated.
Buttermilk | Soak the onion petals in buttermilk for a couple hours instead of water suggested above as it will help the egg and flour stick better.
Panko | Use Panko Breadcrumbs in place of the flour for a crunchier and crispier petal.
Breadcrumbs | Replacing a breadcrumb mixture for the flour will also create a crunchier exterior.

Making a blooming onion is pretty simple. Peel and slice the onion so it can peel apart easily. Dip it in the wet mixture and then dry batter. Air fry until it is golden brown.
Blooming onions are generally served with a dipping sauce that carries a little spice: Boom boom sauce, Sriracha, mayo, etc. Serve this as a side dish with your burger, or even as an appetizer to cheer on your favorite teams.
Tim Gannon from the Outback Steakhouse created this incredible savory invention.
Cook in the air fryer for 9-15 minutes. The time will vary slightly depending on the size of the onion. For larger onions you will need to extend the air fry time.
No. You should use an oil mister and not cooking spray. Cooking spray may damage the enamel on the Air Fryery tray.
