Method 1: Reheating Using the Oven

The first and best method for reheating a bloomin onion is reheating it in the oven/toaster.

The popularity of this method is due to the fact that it preserves the bloomin onion’s crispiness, and will have it tasting close to when it was originally made.


  1. Preheat your oven to about 350 F – 375 F (180 C – 190 C )
  2. You can spray the bloomin onion with some cooking oil to ensure it doesn’t stick to the pan and it will help keep its texture and crispiness while reheating.
  3. Place in oven for about 10 minutes or until heated through.
  4. Once heated to your liking, remove from the oven and serve.

Method 2: Reheating Using The Air Fryer

The second best way to reheat a bloomin onion is by using an air fryer.

An air fryer will have your food tasting crispier than ever before, as it circulates hot air around whatever you’re cooking. In this case, a leftover bloom onion would be reheated evenly, while retaining its crispy texture!


  1. Preheat your air fryer to about 360 F (182 C)
  2. Spray the air fryer basket with cooking oil, then give the bloomin onion a spray of oil as well.
  3. Let the bloomin onion air fry for about 5-7 minutes, or until heated through.
  4. Once reheated to your liking, remove from air fryer and serve.

Method 3: Reheating in a Skillet/Deep Fryer

Using the same method as when cooking a bloomin in the first place, you can reheat it in a skillet or deep fryer.

This is not the ideal option, as you will be essentially re-frying the bloomin onion, which may result in it becoming soggy and less crispy. It is also not the healthiest option, as compared to reheating in the oven or air fryer.

Steps: Skillet/Frying Pan

  1. Preheat your skillet or frying pan to medium-high heat.
  2. Add some oil and place bloomin onion in the pan and cook for about 2 minutes per side, or until heated through.
  3. Once reheated, remove and let it sit on a cooling rack for a minute to release the steam and then serve.

Steps: Deep Fryer

  1. If you have a deep fryer, simply follow the same process as if you were cooking one fresh.
  2. The bloomin onion will come out crispier, but remember, you are refrying it, so it may not be as healthy as the oven or air fryer methods.

Can You Reheat a Bloomin Onion in the Microwave?

Reheating fried foods in the microwave is a recipe for disaster.

It is not recommended for bloomin onions, as when a crispy food like that is microwaved, the moisture in it is released and steams up.

The bloomin onion will essentially start to steam itself from within, which can make its exterior soggy and unpleasant for consumption.

If you don’t care too much about the crispy texture and want to heat it up as quickly as possible, then microwaving might be an option for you.

But, we do not recommend it.
