There are lots of convenient ways to reheat a bagel, from the oven to the air fryer and even in the microwave. They won’t all give you the results you’re after, though. So let’s talk about the best ways to reheat a bagel.

While there are different ways to reheat a stale bagel or day-old bagel, today we give you three of the best methods (and one not so great one) to reheat a whole bagel. If you are looking for a great way to revive stale bagels, below are your options. 

Method 1: The Oven

Reheating bagels in the oven is often preferred over other methods because of several key reasons:

  • Texture Retention: The oven’s dry heat helps restore the exterior’s signature crispiness while maintaining the chewy interior. Microwaving, in contrast, can make bagels soggy or overly chewy.
  • Even Heating: The oven provides consistent heat distribution, ensuring the entire bagel is uniformly warm. Microwaves sometimes cause uneven reheating, leading to hot spots or cold sections.
  • Avoiding Sogginess: When reheated in an oven, there’s minimal risk of the bagel turning out soggy, as can happen with methods introducing moisture.
  • Freshness Rejuvenation: For stale or day-old bagels, the oven does a better job of reviving their freshness than other methods. A short stint in the oven can often bring a stale bagel back to life, making it almost as good as fresh.
  • Versatility: If you add toppings like cheese or butter, the oven melts them perfectly over the bagel.
  • While there are faster methods like the microwave or toaster, using the oven to reheat bagels helps retain or even rejuvenate their original taste and texture, making for a much more enjoyable eating experience.

​How To Reheat A Bagel In The Oven

Reheating a bagel in a regular oven is simple and effective. Here’s a step-by-step guide to doing it right:

  1. Preheat the Oven: Set your oven to 375 degrees Fahrenheit (190°C) and let it preheat.
  2. Prepare the Bagel: If your bagel is sliced, it’s best to reunite the two halves to prevent the cut sides from drying out too quickly. Place the bagel halves back together as if they were whole.
  3. Wrap in Aluminum Foil (optional): If you’re worried about your bagel drying out, especially if it’s a day old, you can wrap it loosely in aluminum foil. This step can help retain moisture. However, you can skip this step if you prefer a crispier crust.
  4. Place in the Oven: Once the oven reaches the desired temperature, put the bagel directly on the wire rack or a baking sheet. Place the wrapped bagel on the rack if you’ve wrapped it in foil.
  5. Heat: Let the bagel heat for about 4-5 minutes. If you want it to be a bit crispier, leave it in for a minute or two longer. Keep a close eye to ensure it doesn’t overheat or become too hard.
  6. Check the Bagel: Carefully touch it to ensure it’s warmed to your liking. Give it another minute if it needs more time, but be cautious not to overdo it.
  7. Serve and Enjoy: Once adequately heated, remove the bagel from the oven using oven mitts or tongs. If you wrapped it in foil, be careful when unwrapping it to avoid steam burns. Slice (if necessary), add your favorite toppings, and enjoy!

Note: Ovens can vary, so the first time you try this method, keep a close eye on the bagel to ensure it heats to your desired level.

Method 2: The Air Fryer

Reheating bagels in an air fryer has become increasingly popular due to the device’s unique benefits. Here’s why you might consider using an air fryer to reheat your bagels:

  • Crisp Exterior, Soft Interior: One of the standout features of an air fryer is its ability to recreate a crisp exterior while maintaining a soft and chewy interior. Bagels reheated in an air fryer often have that freshly-baked quality, with a crisp crust and soft, warm insides.
  • Speed and Efficiency: An air fryer heats up quickly and circulates hot air around the food, allowing it to reheat faster than a conventional oven.
  • Even Heating: The rapid air circulation ensures that the bagel is heated evenly from all sides, preventing cold or overly dry spots.
  • Less Energy Consumption: Using an air fryer can be more energy-efficient than heating a large conventional oven to warm a bagel or two.
  • Flexibility: You can control how toasted or warm you want your bagel by adjusting the time and temperature settings.
  • Space-Saving: An air fryer is a compact alternative for those with limited kitchen space or who don’t want to heat their large oven for a small task.
  • Reduces Staleness: If your bagel is a day old or a bit stale, the air fryer can bring it back to life, making it taste almost as fresh as the day it was baked.

In summary, using an air fryer to reheat a bagel can provide a near-fresh bakery experience in the comfort of your home, making it an excellent option for bagel enthusiasts.

The air fryer is one of the ways to reheat a bagel!

How To Reheat A Bagel In An Air Fryer

Reheating leftover bagels in an air fryer is a straightforward process that results in a crispy exterior and soft interior, closely mimicking a freshly baked bagel. Here’s how to do it:

  1. Preheat the Air Fryer: Start by preheating your air fryer to 350 degrees F (175°C) for a few minutes. Preheating ensures even reheating of the bagel.
  2. Prep the Bagel: If the bagel is sliced, keeping the halves together is recommended to prevent the cut side from becoming overly toasted. If it’s unsliced, you can either reheat it whole or slice it first, depending on your preference.
  3. Place in the Air Fryer: Once the air fryer is heated, place the bagel(s) in the air fryer basket in a single layer, ensuring they aren’t overlapping or touching.
  4. Reheat: Set cooking time for 3-4 minutes. If you’ve sliced it, you may want to check it at the 2-minute mark to ensure the cut sides aren’t getting overly crispy. The exact time can vary based on your specific air fryer model and the size and thickness of the bagel, so you might need to adjust the timing accordingly. Mini bagels in the air fryer will take about 1-2 minutes. 
  5. Check and Enjoy: Once done, carefully remove the bagel from the air fryer (it will be hot) and let it sit for a minute. Enjoy it warm with your favorite toppings!

Notes:

  • Don’t overcrowd the air fryer. You might need to do it in batches if you’re reheating multiple bagels.
  • Remember that reheating times can vary based on your specific air fryer model, so keep an eye on your bagel the first time you try this to get a sense of the perfect timing for your device.

Method 3: The Toaster Oven

Reheating bagels in a toaster oven is one of the best methods to regain that fresh-out-of-the-oven taste and crispiness. Here’s how to do it:

How To Reheat A Bagel In A Toaster Oven

  1. Preheat the Toaster Oven: Start by preheating your toaster oven to 350°F (175°C). This ensures that the bagel will be heated evenly.
  2. Cut the Bagel: If your bagel isn’t pre-sliced, use a serrated knife to slice it in half horizontally. Slicing the bagel helps the heat penetrate the dense interior, ensuring it warms thoroughly.
  3. Place in the Toaster Oven: Arrange the bagel halves cut-side up directly on the oven rack. The middle rack works best.  This helps the cut side get crispy while preventing the exterior from becoming too tough.
  4. Heat: Toast the bagel halves for about 3-5 minutes. Keep a close eye on them to avoid over-toasting. The goal is to warm them and slightly crisp the cut side without drying them out.
  5. Check for Warmth: After 3 minutes, touch the cut side of the bagel to see if it’s warm enough for your liking. If not, continue heating in 1-minute increments until the desired warmth is achieved.
  6. Serve Immediately: Once the bagels are warmed to your preference, remove them from the toaster oven using oven mitts or tongs. Serve immediately with your choice of toppings.

Note: If your bagel is a day or two old and has started to get a bit hard, you can lightly sprinkle the cut side with water before putting it in the toaster oven. This will help to reintroduce some moisture and make the bagel more palatable.

Method 4: The Microwave

Reheating bagels in the microwave is quick and convenient, but it may not yield the same crispy exterior as an oven or air fryer. However, the microwave can do the trick if you’re in a hurry. Here’s how:

How To Reheat A Bagel In A Microwave Oven

  1. Slice the Bagel (Optional): If you prefer, slice the bagel in half. This can help it heat more evenly and prepare it for your favorite spreads or toppings.
  2. Dampen a Paper Towel: Lightly moisten a paper towel. This will help prevent the bagel from becoming too hard or rubbery. You want the paper towel to be damp, not soaking wet.
  3. Wrap the Bagel: Wrap the sliced or whole bagel in a damp paper towel. This helps retain moisture during the reheating process, ensuring a softer result.
  4. Microwave on Low to Medium Power: Place the wrapped bagel in the microwave or place it on a microwave-safe plate. Set the microwave to 50% power (or use the ‘defrost’ setting). Heat for 15-20 seconds, then check its warmth. If it’s not warm enough, continue microwaving in 10-second intervals until it reaches the desired temperature. Be cautious not to overheat, as microwaving can quickly turn the bagel rubbery. The average time is 10-15 seconds. 
  5. Serve Immediately: Once reheated to your liking, remove from the microwave, unwrap, and enjoy immediately for the best texture. Add your favorite toppings or fillings.

Note: Every microwave is different, so adjust times as necessary. Using lower power settings helps achieve a more even reheating without making the bagel too chewy or hard.

Reheating Bagels Recipe Tips

  • Skip the Microwave: While microwaving is a quick option, it can leave your bagel rubbery and chewy. Stick to the air fryer, oven, or toaster oven for a crisper exterior and soft interior.
  • Avoid Sliced Bagels If Possible: If your bagel is already sliced, be cautious; the cut sides can toast quickly, becoming overly crispy or even burnt. Keeping the halves together when reheating can help.
  • Lightly Hydrate: If your bagel has dried out a bit for oven reheating, you can lightly sprinkle it with water before popping it into the oven. This helps steam it slightly and revives its chewiness.
  • Check Periodically: All ovens and air fryers vary in their heating capacities. Always check your bagel halfway through the recommended reheating time to ensure you’re not over-toasting it.
  • Preheating is Key: Always preheat your air fryer or oven. This ensures that the bagel reheats evenly.
  • Monitor the Fillings: If you’re reheating a stuffed or filled bagel, remember that fillings like cream cheese can become very hot. It’s best to remove fillings and reheat or spread them afterward.
  • Let Rest for a Moment: After reheating, let the bagel sit for a minute or two. It continues to “cook” a little from residual heat, and this brief rest can make it perfect.
  • Day-Old is Best: While these methods can revive slightly older bagels, they’re best used on bagels that are only a day old. Beyond that, consider using older bagels for breadcrumbs or croutons instead.
  • Toppings: If your bagel has toppings, like seeds or cheese, keep a close eye on them during reheating. These can burn or over-crisp faster than the bagel itself.
  • Storage: If you plan to store your bagels for over a day, consider freezing them. They’ll retain their quality better, and both the oven and air fryer handle reheating from frozen pretty well (adjust the time).

With these tips in hand, you’ll maximize the taste and texture of your reheated bagels, ensuring a delightful eating experience.
