How To Reheat Grilled Hamburgers? (3 quick & simple methods)

Hamburgers are a staple of American cuisine that can be enjoyed for breakfast, lunch, or dinner (dessert lol), depending on your preferences…


And the best part is that hamburgers are quite adaptable. As for leftovers (yessir), while a burger in a bun that has been prepared and tasted delicious isn’t exactly something you want to waste. Even a single burger that has been sitting out for a day can lose its flavor.


How To Reheat Grilled Hamburgers?

Reheat burgers in the oven or toaster oven for 8 minutes at 350 degrees. Covering the burger in foil before cooking ensures even cooking.


After conducting additional research, I discovered additional information that you should be aware of, so please continue reading…



Disassembling of the Burger

Separate the patties from the rest of the burg in order to achieve the best overall outcomes. Stephanie must be disassembled! Yes, it is necessary to disassemble! Follow the instructions outlined below (thank me later).


Step 1: Bring your hamburger to room temperature before serving it. At typical room temperature, twenty minutes on the counter, loosely wrapped, should be sufficient time. Keep in mind that it should not be left out for longer than 2 hours. A full burger will be easier to separate from its constituent portions as a result of this.

Step 2: Remove the Condiments and Buns from the Pan. After your sandwich has cooled to room temperature, remove all of the condiments and bread from the sandwich. Carefully separate the buns, meat, and condiments from one another. If your buns are cold, they may become stuck to the patties and tear when you try to remove them.


Top 3 Methods For Reheating Your Grilled hamburger

1. TheMicrowave Method


Ever put a hamburger in the microwave for an unknown amount of time, clicked the start button, and then walked away from the kitchen?


If this sounds like the way you reheat hamburgers, you’re not alone in your thinking… While this procedure is effective, the burgers produced are less than appetizing in appearance.

Yea yea yea, I understand that sometimes life gets in the way and you need to get dinner on the table as soon as possible, which is why the microwave is at the bottom of the list when it comes to the best way to reheat grilled hamburgers. 


  • Locate the “reheat” button on your microwave’s control panel. In order to reheat a hamburger, you’ll want to use this feature.

  • Place the hamburger patties on a microwave-safe plate and microwave for 30 seconds.

  • Microwave the hamburger patties for one to two minutes, depending on their size. In some cases, depending on how thick the patties are, you may need to turn them midway through the cooking time.

  • Make a downward motion with your finger through the warm patty. If the patty is still hot when you do this, it’s time to finish it. If this is the case, reheat for an additional 30 to 60 seconds.

  • You may also reheat Hamburger Helper in the microwave by following these steps (and as always, you can thank me later lol).


2. The Oven Method


The oven, how I love thee. For some reason, this classic appears to have withstood the test of time again and time again. And when it comes to a foolproof method of reheating a hamburger, the oven is the only option available.

This is the preferred approach for burger connoisseurs such as me, so you can rest confident that you’ll be eating a burger that tastes just as good as one that’s just come off the grill.


  • Make sure your burger is prepared to perfection before you start eating it.

  • 400 degrees Fahrenheit is a good temperature for your oven to be at.

  • Prepare a metal rack and set it over a baking pan to prevent the excess fat from dripping all over the oven floor.

  • Placing the patties in the oven for approximately three minutes, depending on the strength of your oven, should yield good results.

  • Once the three minutes have passed, place your bun on the metal rack and turn your patties to the other side.

  • Cook for a further two minutes, or until the bun is a gorgeous golden brown color throughout.

  • While you’re doing this, you may put your hamburger buns in the oven to get that toasty finish you’ve been wanting.

  • Dress up your burger with your favorite vegetables and additions, and then sit back and enjoy!


3. The Toaster Oven Method


When it comes to selecting an effective and efficient method of reheating a hamburger, the toaster oven comes in a close second to the oven…

The fact that a hamburger patty is on the smaller side means that they tend to reheat rather nicely in an electric toaster oven. Consequently, if you are an expert at using a microwave oven, you may want to stay with this method for reheating hamburger patties.


  • Depending on your toaster oven, heat it to 350 to 400 degrees Fahrenheit. If the hamburger patties are at room temperature, they will reheat in a relatively short period of time.

  • In a toaster oven, lay the burgers on a metal rack and set a baking sheet underneath them to catch any excess grease that drops.

  • Cook the meat patties for roughly three minutes on each side until browned.

  • Cook the hamburger patties for an additional two minutes after turning them (the exact time will depend on the thickness of the patty).


Choosing the best ground meat for hamburgers is a difficult task (but I got your back)

Make sure to use the best quality ground beef you can find, regardless of whether you want to have leftovers. Inquire about the amount of fat in the patty; the higher the percentage of fat, the better the flavor and the moister the patty.


The amount of fat in ground beef is expressed as a number. 90/10 refers to the fact that the meat is 90 percent meat and 10 percent fat. 80/20 and 70/30 are two other frequent ratios to consider.

You won’t end up consuming the entire amount of fat. During the cooking process, it will render down and keep the meat moist.


Cooking delicious hamburgers (a few pointers for best results)

Season the ground beef with salt and pepper to taste, but handle it gently. You don’t need to knead or beat it; simply mix in the ingredients with a spoon before forming the patties.


Before grilling the patties, form a little dimple in the center of each one with your fingertip before pressing it down. This helps to avoid shrinking. Never press down on the patties while they’re grilling because this will cause them to fall apart.


You’ll lose both the fat and the juiciness of your meat. Make sure not to overcook your burgers. It’s difficult to know when they’re done to your satisfaction because the width of the slices and the temperature of your grill both affect the outcome.


Take one off the grill and open it with a fork to make sure it’s done when it appears and smells correct. If it is, remove it from the grill and replace it with the others.


Freezing extras to reheat later (how to do it correctly)

FIRST THING FIRST: Refrigerate or freeze cooked hamburger patties as soon as possible once they are finished cooling completely. Freeze the patties in individual baggies with a teaspoon of water to prevent them from sticking together.

NEXT: Refrigerate them to thaw them out. Reheat in a baking pan in the oven at 350°F for about 15 minutes. Using a microwave, you may quickly reheat frozen patties by placing them in a plate with a teaspoon of water in the bottom of it. Cook on low in the microwave for a few minutes, or until it is barely steaming.


Maintaining the temperature of cooked hamburgers

What you may not have realized is that you can use your slow cooker to keep multiple burgers warm while you prepare other foods, or even additional burgers.


Due to the fact that even on a low/warm setting, the hamburgers will continue to cook a little, this is only effective for about one hour. Using a small, oven-safe bowl filled with a few tablespoons of water and placing it in the bottom of the slow cooker can help to keep the hamburgers moist.


The steam that is produced will prevent the burgers from drying out. Place the hamburgers in the slow cooker after they have been cooked. Cover with the glass cover from the cooker.


Set the heat to the warm setting rather than the low level. If your stove does not have a warm option, you should avoid using this method because the low temperature would quickly dry them out.



The process of re-heating commercial hamburgers

Suppose you have one or two leftover hamburgers from a fast-food restaurant like McDonald’s or White Castle in the fridge. Allow them to come up to room temperature first…


  • Cold hamburgers will most likely have cheese or paper on to them, which will cause the patties to rip if you try to remove them while still frozen.

  • Separate the room-temperature hamburgers on greaseproof paper after they have been sitting for a while.

  • Remove them from the buns with a slotted spoon. Remove any condiments, such as onions or pickles, or toppings with care, and wipe away any sauce, mustard, or ketchup that may have gotten on your hands.

  • You can use any of the warming methods discussed above to reheat your food. To enjoy your burger with cheese, reheat it while the cheese is still on top.

  • Fresh sauces, onions, and other ingredients should be placed on top of the hot burger. Place it inside a freshly baked or reheated bread to serve.

FYI: The secret is to wrap the burger in aluminum foil before cooking it to ensure even cooking…


Regardless of whether you want leftovers, use the best quality ground beef you can find. Inquire about the patty’s fat content; the higher the fat percentage, the better the flavor and the moister the patty.


The fat content of ground beef is expressed numerically. The term “90/10” refers to the fact that the meat is 90% meat and 10% fat. Other common ratios to consider are 80/20 and 70/30.


You will not consume the entire amount of fat. It will render down and keep the meat moist during the cooking process. Enjoy the rest of your day, alway stay safe, and treat others with kindness and respect!
