If you’re throwing ground beef on the grill to char you can skip the slow cooking part as it doesn’t add any benefit. Being soft and tender isn’t what you want in a burger.
That is why texture is important. Searing is an important concept in cooking and this applies to burgers.
Would you slow cook a burger? I suppose you could but I wouldn’t. I’d rather have the texture of a grilled burger.
Slow cook the meat, let it cool, throw it on a grill to heat it up giving it the tenderness of slow cooking with that same char.
