What is an Onion Blossom?

Onion blossoms are also known as onion mums or Bloomin’ Onions® (the name Outback Steakhouse® has for their version). Despite these names, this dish doesn’t actually have anything to do with flowers. Instead, it’s a large onion that’s been cut into strips that, when spread out, resemble the petals of a flower. The raw onion is then coated with mildly spicy flour mixture and thrown in the deep fryer before being served with a creamy, tangy dipping sauce.

History of the Onion Blossom

To learn about this deep fried creation, we need to look to the Southern U.S. – New Orleans, specifically. It’s not clear exactly when this dish was first created, but all signs seem to point to the 1980s. The restaurant that advertises itself as “The Home of the Original Onion Mum” is Russell’s Marina Grill in New Orleans, LA, which was founded in 1985.

Why is the Onion Blossom Popular?

Not only is this fried food delicious, but it also has a unique appearance that looks great and is easy to eat. The individual onion slices can be pulled off and dipped in the sauce using one hand, making it simple to carry around at a fair or share over a beer at the local pub. To make it even more portable, the core of the fried onion can be cut out and filled with sauce, or you can choose to serve it on the side like we have.

Most importantly, though, is how profitable the onion blossom is for businesses. With only a handful of ingredients, you can create this unique dish in your restaurant. You can purchase a specialty onion cutter if you find that your prep time is taking too long, but you can also obtain the same appearance by slicing the onion by hand.
