How to reheat bloomin’ onion (4 fantastic ways)

Like onion rings, bloomin’ onion features an incredible flavor and texture that’s out of this world. It’s also a great appetizer, especially when paired with a special sauce made from mayonnaise, sour cream, ketchup, horseradish, and spices. 

I often prepare a batch of bloomin’ onions for movie night along with other finger snacks. There were moments, of course, that I ended up with leftovers so I came up with a solution–REHEAT!

Bloomin’ onion tastes great when it’s just been taken out from the pan filled with hot oil. Some food enthusiasts get intimidated to reheat it because fried foods tend to become soggy or burnt. 

But worry not! Simply use the reheating methods below and trust me, you’ll be able to enjoy the appetizer just as good as the second time around!

How to store bloomin’ onion

Before the warming up process, the first thing that every cook considers is the condition and quality of the food. As a rule, any food shouldn’t be left out for more than two hours at room temperature as this can cause spoilage. It’s also advisable to avoid letting your food leave out at temperatures between 40 and 140 degrees Fahrenheit. 

So what will you do if you have leftover bloomin’ onions? It’s simple–store the food in your fridge! Here’s how to do it:

  1. Place the bloomin’ onion in a glass container with a lid.
  2. Line the container with a paper towel. This process prevents the food from getting soggy.
  3. Fold the sides of the paper towel around the onion. Cover the container with the lid.
  4. Stick it in your fridge.

When properly stored, your leftover bloomin’ onion should last for up to five days in the refrigerator. Make sure to reheat it as soon as possible for the best quality. 

Moreover, I don’t recommend freezing your leftover bloomin’ onion because this process loses the food’s original taste and texture.
