If you’re like me, you probably like preparing your burgers in advance and then freezing them (or maybe you just bought some frozen).

Anyway, there are lots of situations where you find yourself grilling frozen burgers.

There’s nothing wrong or weird about that. Personally, I often grill hamburgers prepared much earlier this way. Sometimes I don’t even have time to slowly defrost burgers in the fridge, which is why I taught myself how to grill frozen hamburgers.

Does it still taste good?

Here’s the trick I use to get perfect burgers.

Are frozen burgers any good?

Fresh hamburgers are definitely the best, but very often we don’t have time or even motivation to prepare them. Properly pre-prepared hamburgers can be frozen and then grilled whenever you like.

An upside to this is saving time, you can prepare a lot of such hamburgers on your day off and then freeze them all. In such condition, hamburgers have a long shelf life, which means you can take out few such burgers once in a while to make a quick and delicious meal.

The main downside of frozen hamburgers is the longer time required to grill them. On top of that, it is a must to take care of all the conditions required to grill evenly so that you don’t end up with raw meat on the inside.

When it comes to the flavor on the other hand, the difference isn’t really quite that huge compared to fresh burgers. Sure, someone experienced may feel the difference, but they will also admit that grilled frozen burgers taste nice.

How to Grill Frozen Burgers Properly

So after a fairly long introduction and quite a lot of theory on the topic, I can now move on to the essence, which is discussing how to properly prepare frozen burgers.

First preheat the grill to a medium temperature, preferably about 300 degrees F. Never start grilling frozen burgers patties on a cold grill, and do take this advice really seriously. All the information in this guide was based on a warmed-up grill ( time of frying etc ).

If you have a charcoal grill then it’s better to do this first. When it comes to certain types of grills, achieving the right temperature takes a lot of time.

Next take the frozen hamburgers out of the freezer and use a wooden spatula to separate them. If you have some spare time, then wait few minutes for the hamburgers to thaw a little. It will be much easier to get them separated and the condiments will stick to the meat much better. So put some salt and pepper on the hamburgers or whatever else you like.

Once the temperature inside the grill is just right, you can start grilling. Place the hamburgers on the grates and close the lid if your grill has one.

From now on, try to flip the hamburgers every 3 to 5 minutes over the next 15 to 25 minutes. It all depends on the freezing level of the meat and on how thick it is.

Normally, burger patties will need between 15 and 25 minutes to cook properly. The cooking time is largely determined by the thickness of the meat. Thicker patties will take longer to cook compared to slimmer ones.


In case you are not sure whether the patties are properly cooked, you can actually use a meat thermometer to measure the internal temperature. A patty should be considered fully cooked if the internal temperature is 160 degrees Fahrenheit.

  • 4 burgers (frozen)


Preheat the Grill

  • Placing burgers on a cold grill is not really a good idea. They will start to stick on the grate once the heat is turned on. In addition to this, the frozen meat will also cook unevenly. This is why the grill needs to be preheated. The appropriate temperature to grill burgers is 325 degrees.
  • In case your grill doesn’t have the tools needed to measure temperature, you can do it manually. Just hold your hands three inches above the grate. If you can hold that position comfortably for 6-7 seconds, then the grill has reached the ideal temperature. Remember that you don’t want to heat it too much.

Separate the Frozen Burgers

  • Frozen burgers are normally separated with a layer of paper between them. This is designed to prevent the meat from sticking to each other. Before you start grilling, the paper separating the patties needs to be removed. You can use a kitchen knife or a metal spatula to do this.
  • In case you are having a hard time getting rid of the paper, let the frozen burger sit on the open air for a few minutes so that some of the ice melts. This should make your work easier.

Grilling Frozen Burgers

  • Place the patties on the grill and let them cook for a total of five minutes and flip them. The burgers should be flipped every 3-5 minutes until they are fully cooked in around 25 minutes. To be 100% sure, you can measure the internal temperature to see that it’s at 160 degrees.
  • Grilling will also cause flare-ups in some occasions. In case you don’t want your burgers to burn in the flame, move them to the side until the flare is out. You can also close the grill’s lid if there’s a flare up so you can put out the flame right away.

To make sure, check the temperature inside the meat using an instant read thermometer, which should show about 160 degrees F. ( When making the measurements, take the beef patties off the grates, and also try to insert the thermometer from the side and not from the top ).

Meat takes 15 to 25 minutes so all that is left for you to do is wait and in the meantime get the buns and other things ready. You can warm up or grill the buns right before taking the meat off the grates if you prefer.

With the meat done and with hot buns, all that is left to do is prepare delicious hamburgers using your favorite toppings.
