  1. Make the dipping sauce: Combine mayonnaise, ketchup, horseradish, paprika, 1/4 teaspoon salt, 1 dash black pepper, and 1 dash cayenne pepper in a small bowl and refrigerate it until needed.
  2. Beat egg and combine it with milk in a bowl large enough to hold the onion. In another bowl, combine flour, salt, cayenne pepper, black pepper, garlic powder, thyme, oregano, and cumin.
  3. Prepare the onion: cut approximately 3/4 to 1 inch off of the top and bottom of the onion, remove skin. Remove the 1-inch diameter core from the middle of the onion. Using a large, sharp knife, slice down the center of the onion about 3/4 of the way down, turn 90 degrees and slice again. Keep slicing the sections in half, being careful not to cut to the bottom, until you have 16 sections. Spread the petals apart to make coating easier.
  4. Dip the onion in the milk, then coat well with the flour mixture. Separate the petals again and sprinkle the flour mixture between them. Once you have coated all of the petals well, dip it into the milk and into the flour mixture again. Place in the refrigerator for at least 15 minutes while you preheat the oil.
  5. Pour enough oil to cover the onion into a deep fryer or deep pot. Preheat the oil to 350 degrees F (175 degrees C).
  6. Fry the onion right side up in the oil for 10 minutes or until golden brown. Remove from oil and let drain in a rack or paper towels. Open the center of the onion wide so that you can put the small bowl of dipping sauce in the center.

if you slice the onion and then soak it in ice water for about an hour it will "bloom" or open up so you can serve it like the Chilis and Outback do. The souce is great.

To be fair, I think my onion was too small. The dip is delicious and will use it on other things.

This is by far the best blooming onion I have ever had. I am now using this recipe for mushrooms and zucchini as well.

This is an excellent recipe. Not only does it make a great "blooming onion", but it also makes great onion rings, if you prefer them. And it makes good onion petals, too.

This is basically the same exact recipe as the "Blooming Onion and Dipping sauce" recipe on the site. Its a very good recipe and makes great blooming onions. And the sauce is delicious! Just make sure to warm it up slightly before serving. I just dont think it tastes as good cold. If you are scared or have had failed at making blooming onions in the past I have some great pointers to help make one perfect. Look at my review for the other Blooming Onion recipe on the site and I have more detailed info there. I used to never be able to make them until I did a couple steps differently and now they turn out perfect!

We were craving the blooming onion after seeing a billboard for Outback Steakhouse. This recipe was awesome, we had fun getting everything together and it turned out great!!! Thank you for an easy and tasty recipe.

This was very good...very similar to other blooming onion recipe on this site. Like them both equally. You do need to soak the onion in an ice bath for at least an hour in order for it to actually bloom (like other reviewers suggested). Thanks for the post.

After seeing a commercial on TV for the Outback Steakhouse, I got a craving for their Bloomin' Onion. This recipie was absolutely perfect! I made onion rings based on others' reviews, so it was easy and delicious! The dipping sauce is also just what I was looking for. My boyfriend wants to keep it around for dipping other foods, too. Thanks!
