How To Cut a Blooming Onion

It’s not hard to cut a blooming onion – you just need the right technique:

Cut 1/2 inch off the top of the onion and peel off the outer layer.
Flip the onion over so that it sits flat on the cut side (with the root side up).
Starting 1 inch from the top (root), cut downward all the way to the bottom. (The onion pieces should stay attached to the root at the top.) Make 8 slices going all the way around the top of the onion, like a pie.
Spread the petals. Flip the onion over again so that the root is down, and gently spread apart the onion petals to make it bloom.

How To Make a Keto Blooming Onion

Now that your onion is cut properly, let’s make a low carb blooming onion – you just need the right breading!

Make breading. In a large bowl, mix crushed pork rinds, almond flour, paprika, garlic powder, salt, and pepper together.

Make egg wash. In a large bowl, pour the beaten eggs over the onion, coating the onion with the egg. Using the basting brush, make sure as much of the onion is covered with the egg as possible.
Add breading. Add the onion to the bowl with the dry ingredient mixture and coat the onion, spreading the petals part to reach every single one.

Bake. Using a lined baking sheet, bake the onion until golden brown. If the tops of the onion start to brown after 15 minutes, add foil to the top to prevent burning.

Serve immediately!

Low Carb Blooming Onion FAQs

Is a blooming onion keto friendly?

Most blooming onions from a restaurant are going to be breaded with flour and deep fried, so definitely not keto friendly.

Fortunately, this keto blooming onion recipe is perfectly keto friendly, thanks to the pork rind and almond flour breading.

What kind of almond flour is okay to use?

For the right texture, it’s important to use super fine blanched almond flour for this low carb baked blooming onion.

Can I use coconut flour?

No, sorry. Coconut flour doesn’t work as well as a breading.

If you’re looking for something with coconut flour, try coconut flour blueberry muffins instead, or one of my other coconut flour recipes.

Can you make it without pork rinds?

Yes, you can substitute the pork rinds with more almond flour. Howwever, it will be less crispy this way.

Keto Blooming Onion Storage Instructions

Can you make it ahead?

I would recommend making this recipe right before serving, as it will be best served fresh and straight from the oven! It will get soggy as it sits.

How to store a gluten-free blooming onion

Store any leftover blooming onion in the refrigerator for 2-3 days.

Can you freeze keto blooming onion?

I don’t recommend freezing it – the breading will be soggy after reheating.

How to reheat a blooming onion

For best results, reheat blooming onion on a cooling rack (so that the hot air surrounds the onion) in a 375 degree F oven or an air fryer.

Preheat oven to 350 degrees F (176 degrees C). Line a baking sheet with parchment paper.
Cut 1/2 inch off the top of the onion and peel off the outer layer. Flip the onion over so that it sits flat on the cut side (with the root side up). Starting 1 inch from the top (root), cut downward. (The onion pieces should stay attached to the root at the top.) Make 8 slices going all the way around the top of the onion, like a pie. Flip the onion over again so that the root is down, and gently spread apart the onion petals to make it bloom.
In a large bowl, mix the crushed pork rinds, almond flour, paprika, garlic powder, salt, and pepper.
In a small bowl, whisk in the eggs, until uniform and frothy.
Place the onion into a large bowl. Pour the beaten eggs over the onion, coating the onion with the egg. Using a basting brush, make sure as much of the onion is covered with the egg as possible.
Pour the dry ingredient mixture over the onion, using your hands to make sure the mixture is sprinkled over hard-to-reach areas.
Transfer the onion to the lined baking sheet. Bake for 25-30 minutes, until golden brown. If the tips of the onion start to brown after 15 minutes, tent the top with foil to prevent burning, then continue baking.
