take your beans and chop em how you want em, whether that's Not At All if you're some kinda freak who likes Long Beans, cutting them in half like my lazy ass does, or doing some weird biased french cut bullshit, give them that slice
now take some oil (or butter) and grease those bad boys up. Throw in some minced garlic, some onion powder, some garlic powder because you can't have too much garlic, some salt and pepper, and maybe a little thyme
now go roast those fuckers at 400 degrees for like idk 10 minutes before you check on them. They should be wilted, browning, starting to char in some spots. If not, wait a little longer until they are
this is how you roast a green bean
I'm telling you this because apparently I roast a pretty mean green bean, since these college kids will eat like 10Ib of them when I make them (versus <5Ib when the other cooks make them) so I guess I have some sort of Special Knowledge here
my guess is the other cooks are skimping on the garlic
If they're lucky these kids will get beans sprayed with PAM and sprinkled with salt and pepper before being roasted at like... idk how they're roasting them but they're the equivalent of if I roasted them at 400 for like 5-6 minutes. they just look steamed, which they probably are from overcrowded pans
i don't want to shit on the PAM too hard because I've done it before when really pressed for time, but like, idk if I've ever seen anyone really properly season the vegetables but me
