How to Make a Bloomin’ Onion

Bloomin onion recipeBloomin’ onions conjure up memories of eating out with my family. I feel like I always wanted to order this appetizer when I was in middle school and out to dinner with my grandma.

Now that I have a better idea of how often I actually should be indulging in fried foods, I don’t suggest ordering it as often. 🙂 But I still love a bloomin’ onion as a special treat.

Impress your friends with this bloomin onion recipe!I also think this is a dish that could really impress your next dinner guests. A big bloomin’ onion is a fun dish to fry up for a family birthday dinner or a special night in with friends.

I was a little intimidated to make one, but after reading a few recipes and watching a few YouTube videos, I decided to give it a try. Here’s what I did:

Homemade bloomin onionNow let’s talk dipping sauce. If you want to keep it simple, I think honey mustard, ranch or even just ketchup make a great side for this bloomin’ onion. If you want to get a little more fancy try mixing together:

1/4 cup mayonnaise
1/2 teaspoon ketchup
1/2 teaspoon Worcestershire sauce
1/2 teaspoon sriracha
1/4 teaspoon cayenne

Easy bloomin onion recipeThese are best served just after frying. But if you need to make them a few hours ahead, warm them in the oven in low heat to keep it toasty and delicious. Enjoy! xo. Emma

Calories 947kcal


  • 3 large onions sweet
  • 3 cups flour
  • 1 teaspoon cayenne
  • ½ teaspoon oregano
  • 1 teaspoon garlic salt
  • ½ teaspoon cumin
  • ¼ teaspoon pepper
  • 3 eggs
  • 1 cup milk
  • oil for frying


  • Cut off the top of onion and peel off the outer layer. Place the onion cut side down and make cuts into the onion about 1/2 inch from the top roots. Do this all around the onion to create the petals. Now flip the onion over and gently pull apart the petals. If you need to slice them a little more here you can. Optional: use a melon baller to remove the center area so you can add a dipping sauce cup later. Be sure not to cut down too far otherwise your onion could fall apart.
  • In a large bowl mix together the flour, cayenne, oregano, garlic salt, cummin and pepper. Place the onion cut side down into the flour, place a plate over the top of the bowl and give it a few shakes. Flip the onion over and take care to make sure flour gets in between each of the petals. In another large bowl whisk together the eggs and milk. Shake off any excess flour. Dunk the onion, cut side down, into the egg mixture. Flip it over and take care to get the egg mixture gets in between each petal (this is serious guys!). Now place the onion back in the flour mixture and coat it once again. Taking care to… well, you get it by now.
  • Pour enough oil in a large pot or deep fryer so that the onion could float. Heat the oil to 375°F. Fry the onion, cut side down in the oil for 3 minutes then carefully flip the onion and allow it to fry for an additional 3 minutes. Remove to a plate covered in paper towels and shake a little salt over the top.


I made three at once but you can make as many as you think you’ll need for your event, just change up the number of onions you use.

    I think the cut up onion is suppose to be soaked in ice water in order for the onion to “BLOOM”. Then proceed to bread it.

  • this looks amazing #1 — but #2 — how adorable is that checkered napkin/place-mat? too cute! cannot wait to try this!

  • Really good looking. I tried one, similar to this, once … but I baked it because I’m not good at frying things. It was good, but I had to bake it a long time and it got a little burned, or dried … I think I’ll try frying after reading this. Great! Thanks!

  • These look yummy – and remind me of onion bhajis!
