    Be sure to mix the 1 cup of flour into the panko mixture. I also think this calls for more than 1/4 cup of buttermilk. We had to add much more to get our batter to look like the picture.

    I completely agree! The way they wrote this recipe is terrible. No need to put the Panko in with the milk and egg mixture... it just got clumpy and wouldn’t go into the onion. But it’s cooking now and I’m attempting, we’ll see how it turns out.

    So I tried this recipe and my Panko mixture got clumpy. What did I do wrong?

    Bloomin onions are the absolute best and I love the thought of adding a touch of heat to the original recipe. That delicious dip sounds like the perfect accompaniment too!

    I've never even had a regular deep fried bloomin onion! This looks amazing. Definitely on my wish list is an air fryer and will save this recipe to try then.

    I don't know if it would fit in our fryer, but I'm willing to give it a shot! We love bloomin' onions!
