This is both a bad and a fair/reasonable take. Here’s the thing: Smash burgers usually make the other elements of a burger stand out, while making the meat complimentary of all of the other aspects of a burger. In my opinion, that’s why it’s good.
If you have insanely high quality ground chuck (which is a bit antithetical imo), then you can make the ground patty the star of the show. If you’re going for a flavor of pure meat, then that’s awesome. FWIW, that’s how I make my burgers 50% of the time, especially during american holidays like Memorial Day and the 4th of July. Nothing wrong with that at all.
But sometimes you just want a flavor diversity explosion, and just your ground beef isn’t gonna give that to you. That’s where the smash burger comes in. You get a crusty, juicy maillard burger patty (or preferably two) absolutely covered in delicious melty, salty American cheese, with some sweet grilled onions, and the bite of a nice mustard. Then add a few veggies of choice on a pillowy bun, preferably a fresh potato roll. Sweet mama christ, there’s nothing like it!
A good smash burger is a symphony of textures and flavors, all contained in a handheld vessel. No aspect of the burger is more important than the next, because they work in concert to elevate each other. So you get the opportunity to min-max not only the burger patty, but the quality of the pickles, cheese, mustard, bun, etc., and additional components end up mattering. That’s the beauty of the smash burger. The sum of its part are so much greater than the whole, but only when you do it right.
Smash burgers are a different beast than the classic thick patty burger, but they deserve just as much adulation and reverence. I hope someday you find the second side of burger-Jesus and experience a truly great smash burger, my brother in meat.
