Copycat Texas Roadhouse Onion Blossom Recipe

Not to be confused by the equally famous Cactus Blossom by Texas Roadhouse which cuts and separates its onions into separate petals, this copycat Texas Roadhouse Blooming Onion recipe gives you a beautiful whole fried onion in the form of a flower. It’s got that zesty crisp coating seasoned with cayenne pepper, paprika, and garlic powder. The combination of cornstarch and beer in the blooming onion batter is what makes it really crispy. Of course, this crunchy onion snack won’t be complete without the creamy chili dipping sauce! It may look intricate but it’s actually simple to make at home. Serve it with Texas Roadhouse rolls and some ice cold soda. 

Tips on Making this Texas Roadhouse Blooming Onion Recipe

It has never been so easy to have your favorite restaurant foods right at home with trusty copycat recipes like this one. Here are the best helpful tips on how to make Blooming Onion:

  • Use the largest yellow or white onions you can find. The bigger they are, the prettier your onion blooms will be!
  • White onions are a bit more pungent than yellow onions. The pungent flavor cooks off while frying. But if in case you still find it too pungent, you can lessen this by soaking the sliced onion in ice water for at least 30 minutes. The pungent onion juice will be mellowed down by the water.
  • Fry on a heavy-bottom frying pot. A dutch oven will be ideal for this, as well as a deep fryer. It’s important that the pot is roomy enough for the onion to bloom and expand. 
  • Make sure that the oil is hot enough. The last thing you want is a soggy bloom which will be the result if the oil is cold! The oil temperature should be at no less than 350 degrees F throughout the cooking.
  • Customize the Blooming Onion sauce recipe. It’s made with a blend of mayonnaise and sour cream for the perfect creamy and tangy balance. You can add more or less chili sauce depending on your preferred level of spiciness.

How long is a Blooming Onion good for?

This Texas Roadhouse Blooming Onion recipe is best consumed immediately when it’s hot and crispy! It’s not ideal for making ahead as the breading will eventually lose its crispiness.

How do you crisp up a Blooming Onion?

A Blooming Onion is at its crispiest right after it’s removed from the fryer. If you’ve got leftovers which have already turned soggy, you can try deep frying it again to make it crisp up. You can also reheat it using an oven toaster on Medium heat for 6-10 minutes.
