I have a small restaurant and we serve hamburgers. But we are trying to speed up service and thinking of ways to do that. We don't have a commercial grill, so heating up a grill takes too much time. I thought that it might give our hamburgers the benefits of a grill (marks, smokey flavor) if we grilled both sides of the patty for a minute each and then freeze them. Then, when a customer orders a burger, just grab one patty from the freezer and pan fry it the rest of the way. Could that possibly turn out well? If so, any tips or tricks?

    My intuition says no, but I cannot think of a reason based on the food science that this shouldn't be.... erm... feasible. Why not try it with one or two burgers for family meal and find out?

I understand the challenges of running a small restaurant, I've experienced the extremes of the problems. During tourist season I always hired help, but during winter it was just me - Bartender, waitress, cook, dishwasher, bookkeeper, janitor - you name it. Occasionally buses would pull up and unload 30 people on me at once, of course I was never prepped for that. I had some tricks up my sleeve just for that occurrence.

As far as par-cooking your burgers in advance, don't do it. You will lose juiciness, I know this from experience. Besides, if you fully cook par-cooked burgers from frozen, you're really not saving any time after they're ordered. Grill marks don't matter, you don't see them anyway. You're much better off being sure that the patties are of excellent quality to begin with.

The scope of your question is such that all I can really say is, "Don't do it." I do have about about a gazillion things I could share with you that might help speed up your service, minimize waste and put out a great product. Meet me in chat, I'm here quite a bit. You could also write questions that are a bit more broad. I'd love to help in a meaningful way.

  • How 'bout asking, "How can I speed up service?" and lay out your particular issues? This much I can say: rotation is everything and caramelized onions are your very best friend.

  • +1 for the comment on grill marks -- unless you're serving them open face, most people are never going to see them.

This is where low temperature cooking (most people call is sous vide, but it is usually a misnomer) can be your friend. You could cook the burgers until done. Chill. Then flash off on grill or even in fryer before service.


We do large BBQ events for construction companies and need 350 burgers done and served in 15 min. We cook to an internal temperature of 155 and then store in beef stock in the fridge. We then toss on the bbq to bring up to temperature.

  • So basically, refrigerated, not frozen? (and kept in beef stock so they don't dry out). And fully cooked, not partially cooked

If the main issue is speed, consider cooking two thinner patties vs. one thick burger. It's easier to overshoot medium rare, but for the more well done burger it'll dramatically speed up your cooking time.

You can also heat a second smaller pan or a cast-iron press, and drop that on top to help speed up the cooking.

(personally, for home, I'll make patties and freeze them raw, but cook them on a sandwich press ... so it cooks from both sides at once. For a restaurant, you might not have the space to deal with extra appliances, and you'd still have to wait for it to pre-head)


We par cook lots of things, often up to about 90% done: chicken drumsticks, sausages, meatballs, and meat patties (hamburgers?)

They are not exactly the same as freshly cooked, but in their normal serving style (covered in sauce, and between other things) they are not noticeable. The freezing/reheating process tends to render out more fat is the main observation

Test some out, and see if you would stand by them in your establishment

I think a better sauce and a better bun are worth more investment to get customer satisfaction

Ohh, and a really tasty slice of beetroot too :-)
