So I might be the last one on the planet to do it this way --
In the past, I've seasoned hamburger patties on the grill -- while they were grilling. And while it works, it wasn't going to work for me last weekend when we were having a bunch of family over for dinner. I wanted to prep as much as I could ahead of time so that I could enjoy them while they were at our house, instead of running around my kitchen like a chicken without a head (sorry, bad visual!) -- so this is what happened.
As I was getting everything out, I though, "Why not season the bottom of the cookie sheet first so that both sides of the patties can be grilled before they hit the grill?".
So that's what I did. Sprinkle seasoning on the cookie sheet. Make patties and then put them on top of the seasoning and move around a little to "catch it all" and waste as little as possible. Sprinkle more on top and voila.
Ready for the grill. (Or refrigerator, in my case -- as I was making them up early in the afternoon long before everyone arrived. This is what happens when there is a baby in the house -- you get stuff done while they are sleeping, even if that means making dinner at 2pm!).
And while I didn't get all scientific about it, it seemed to me that the seasoning stuck to the burger better and less fell through into the grill!
How about you? How do you season hamburger patties?
