A copycat of a favorite appetizer of mine from a steakhouse chain, without all the added carbs!



  • 1 large sweet onion
  • 1 cup pork rind “breadcrumbs” I like this brand.
  • 1/2 tbsp seasoning salt
  • 1/2 tbsp paprika
  • 1/2 tspn cayenne
  • 1/2 tspn fresh ground pepper
  • 1/2 cup coconut flour
  • 4 eggs
  • 4 tbsp heavy whipping cream

Dipping Sauce

  • 3/4 cup full fat sour cream
  • 5-10 dashes of hot sauce (I used this kind)
  • 1/2 tspn onion salt (or onion powder and salt can be used in it’s place)
  • 1 tspn paprika
  • salt to taste, if necessary

Whisk all dipping sauce ingredients, until fully combined.

I recommend making this ahead of time if possible, to allow the flavors to marry. Store in the fridge until ready to use.


  1. Cut 1/4 top off onion leaving the nub at the bottom.
  2. Turn cut side down and cut onion into quarters, then eighths, then 16ths, leaving about 1/4 in. space from the nub.
  3. Turn over onion, so its open, cut off center petals (about an inch in diameter).
  4. Spoon coconut flour over entire onion, separating the petals and making sure everything is coated, even the bottom.
  5. Mix egg wash (eggs and heavy cream) in a small bowl. Spoon HALF of the egg wash over entire onion, making sure to get in between each petal and underneath until its well coated. Don’t be afraid to use your hands to really get in there. This is very important to get the “breadcrumbs” to stick!
  6. In another bowl, whisk together breadcrumbs and seasonings. Place onion inside and coat thoroughly, making sure to get the bottom as well. Turn over and tap off excess breadcrumbs.
  7. NOW REPEAT… pour second half of egg wash over the breaded onion and  more “breadcrumbs”. Make sure every petal is coated front, back, sides and top!
  8. Carefully place onion on a plate and into the freezer for 1 hour. This step is very important to ensure that the “breading” stays on during frying.
  9. Prepare a plate and line it with a couple of paper towels.
  10. To a large heavy bottomed pot, add oil of your choice (about 2/3 full) and heat to 300 degrees. Carefully lower onion into the hot oil, nub side up, for 1 minute. (See video below)
  11. Lower heat to medium low and carefully flip onion over, petal side up. Watching carefully, let fry for an additional 2-3 minutes. (See video below)
  12. Use long tongs to remove onion.  Let drain on the paper towel lined plate.
  13. Serve immediately with dipping sauce.

Please note:

  1. Pork rind “breadcrumbs” are much more delicate than normal breadcrumbs, so you may want to use a small knife to cut off the onion petals as opposed to pulling them off like you would with the original version.
  2. This is not something that you want to cook in an airfryer! I’ve tried it and it was a major fail! As much as I love my airfryer somethings should only be fried in oil. This being one of them!

    1. I tried it in my air fryer which is almost the same thing and it was not good at all. I wouldn’t recommend it. Something about the frying process that makes it work and taste like the real thing.


    1. Hi Hannah! So sorry for the late reply. I always use refined coconut oil. Refined has all the same nutrient benefits as unrefined but less coconut flavor.


  1. I just found a blossom cutter (neat tool) at a thrift store and would like to make keto onion blossoms with it. Glad to have found this recipe. You recommend refined coconut oil…can this be reused afterward?


    1. Wow! I need to find one of those. Thank you for telling me about it! I do reuse my coconut oil. I just filter the debris out by straining it through a mesh sieve and keeping it in a glass jar on the counter.
