Frozen raw beef patties vs cooked refrigerated patties? I love making burgers but it often ends up being very uneconomical since I can only get ground beef in 1kg+ amounts here and it often expires on the same day. Due to its short shelf life, I basically have to munch burgers for breakfast, lunch and dinner for 2 days whenever I buy it. 

Having done that a few times, I'm looking for alternatives. The 2 options I can think of is either preparing the raw beef patties and freezing them or cooking all the patties and putting them in the fridge to be reheated. 

There are cooked and cooled patties available here at the store but they are extremely disappointing. Then again, those are only like 50% beef and filled with bread, water and whatever other crap that doesn't go in a burger patty so maybe the homemade version would be better. I've never tried a frozen raw patty though nor can I find them at the store.

Which would yield better results? Any tips in getting it right?
Freeze them raw.

Prepare/portion/shape all the patties then put them on small square of parchment paper (or waxed paper) square in a single layer on a baking sheet and freeze them as fast as possible in your freezer.

Once they are frozen, stack them an put them in a resealable bag.
