Reheating Method Considerations

Oven Method

When reheating a bloomin onion in the oven, the first thing you need to do is preheat your oven to 425°F.

Use a wire rack inside a large baking sheet tray to place your whole onion on top, as this allows grease to drip off and prevents sogginess. 

Heat the big onion at high heat for approximately 10 minutes or until it achieves the desired crispiness, resulting in a crispy onion.

Air Fryer

Using an air fryer can ensure a crispy crust and texture when reheating a bloomin onion. 

The first step is to reheat your air fryer to 400°F and with the use of huge onion, lay it on top of parchment paper in the air fryer basket.

Lightly spray the top of the onions with a single layer of cooking oil, and cook in the hot air or direct heat for 5-10 minutes or until crisp. There is no need for extra oil.

Examples of popular cooking oils to use are vegetable oil and olive oil, it all just depends on your personal preference.

This method also helps maintain the onion’s flavor and reduces the absorption of calories from oil.

Toaster Oven

Typically large onion are used when making a bloomin ‘onions, but For the best results, consider using a toaster oven for reheating if you’re dealing with a smaller bloomin onion. 

In the first place, the process is similar to that of a conventional oven. 

Set the toaster oven to 425°F and place the onion on a wire rack inside the toaster oven to prevent sogginess. 

Heat for approximately 10 minutes, checking for desired crispiness before removing.

Stove and Pan-frying

For even warming when pan-frying a bloomin onion, the best method is to detach the petals first. 

Heat a small amount of oil in the pan over medium heat, and pan-fry the petals until they reach your preferred level of crispiness. 

Keep in mind that although this method creates good results, it may also result in higher calorie content due to the oil used.


While the microwave is the most convenient way and quickest way, it’s the least recommended method for reheating a bloomin onion. 

Microwaves should only be used as a last resort because they tend to make the onion soggy and can affect the texture and flavor for the next day. 

If you must use a microwave, heat the onion in short intervals, checking on it frequently to avoid overcooking.

Remember that each of these methods has its own advantages and drawbacks. 

To achieve your desired results, consider the factors such as texture, crispiness, and calorie content when choosing the best options for reheating your bloomin onion.

Preparation for Reheating

If it is your first time, before you begin the reheating process, gather all the necessary materials and tools. 

You will need a paper towel, oil, pan or frying pan, skillet, and a deep fryer if you choose the deep frying method.

First, pat your Bloomin Onion gently with a paper towel, which is an easy way to remove any excess oil from the previous cooking session. 

This step is crucial for ensuring a crispy texture upon reheating.

Next, choose your preferred reheating method from the options below:

  • Using a Pan or Frying Pan: Lightly coat the pan with oil to prevent the onion from sticking to the surface. Place the Bloomin Onion in the pan and heat on medium heat for about 10 minutes, monitoring closely. Flip the onion halfway to ensure even heating and crispiness.
  • Using a Skillet: Preheat your skillet over medium heat and add a small amount of oil. Place your Bloomin Onion in the skillet, and cover with a lid to trap the heat. Cook for about 10 minutes and check frequently. A great way to maintain an even, crispy texture is to flip the onion halfway through.
  • Using an Oven: Preheat your oven to 425°F. Place your Bloomin Onion on a wire rack that allows excess oil to drip off, and place the wire rack inside a large baking tray. Bake the onion for 8-10 minutes, making sure to monitor it closely for optimal results.
  • Using a Deep Fryer: If you prefer to reheat your Bloomin Onion using the deep frying method, ensure your deep fryer is set at a temperature of 375-400°F. Carefully place the onion into the hot oil and cook for about 10 minutes. Be cautious during this process, as the oil can become very hot and cause splattering.

As you go through the reheating process, pay close attention to your Bloomin Onion to ensure your favorite appetizer achieves a crispy and appetizing texture.

Bloomin onions, also known as blooming onions, are a popular appetizer in various restaurants like Outback Steakhouse, Red Robin, and Hooters. 

While the original bloomin onion recipe comes from Tampa Bay, many establishments have adapted and customized their own versions of this delicious dish. 

One popular variation of the classic bloomin onion recipe involves changing the coating that envelops each tender onion slice.

In addition to grilled versions, you may also encounter baked bloomin onion recipes that are prepared similarly, but using your oven.

Finally, some restaurateurs have taken the concept of the bloomin onion and created enticing hybrid dishes.
