Ingredients
- Peanut oil, for frying
- 4 large onions
- Beer Batter, recipe follows
- Cajun seasoning, optional
- Ranch dressing, optional
Directions
Fill a large cast iron Dutch oven with enough peanut oil to completely cover an onion by 1-inch. Heat the oil to 350 degrees F over medium heat. Slice top tip of onions off, but do not disturb the root end and gently peel off outer skin. With a paring knife, starting 1/2- inch from the bottom of the onion, slice down to top of onion and continue at 1/4-inch intervals until onion is sliced all the way around (like a mum flower). Gently shake each onion to open the "petals" more. Gently pick up onion and spoon batter onto onion ensuring every part is coated, then gently allow to drain slightly. Carefully place onion root side down into the pan of hot oil and allow it to cook until light brown in color, about 5 to 8 minutes. Remove onion with a slotted spoon and use a knife to pull apart petals that are stuck together. Place onion back into the oil but this time top side down. When the onion turns golden brown, about 5 minutes, remove it with a slotted spoon to paper towels to drain. Repeat with remaining onions. Shake onions with Cajun seasoning and serve with ranch dressing as a dipping sauce.
- Beer Batter
- 2 1/2 cups beer
- 2 cups all-purpose flour
- Pinch Cajun seasoning
- Pinch salt
Whisk together beer, flour and seasonings; let sit on the counter for several hours.

In video, Paula says she would use UNDER 2 cups of beer so that it isn't too thin. THe consistency is shown on video. It is like pancake batter, not heavy cream. I used 1 1/2 cups beer and it was still too thin. I added more flour. I tested it with mushrooms, delish. Then 1/3 of the onion broke off as it went into oil, upside down yet! This "fused" the petals closed! I tossed the leftover, bite-sized chunks of onion petals into oil, they came out GREAT. Crunchy. It gave me the idea to do it this way all the time. Yes, the blooming onion looks pretty, but the problems are immense. If overcooked, the petals turn mushy and you can't pull them out as is intended. I loved the mushrooms too. I will try this again, next time not turning it topside down! I may use club soda next time instead of beer and not overcook the whole onion. I added Old Bay for flavor.

I read that Paula's batter recipe was supposed to be top notch, but something is missing. Either steps have been ommited or this recipe was half-heartedly posted. It was the biggest blooming onion failure I've ever experienced. The batter didn't stick, so most petals were simply onion sticks, and the batter taste was pretty bland compared to most other dusting methods. Very disappointed. I hope she revisits this one and corrects whatever the problem is. I refuse to believe that this recipe is just this bad.
