Turn on the grill to medium, then brush the grill with oil if you haven't already. When the grill plate is hot, use a fatty meat part or an onion to spread the oil evenly so that the meat will not stick to the pan.
Put your vegetables on the grill first because they take the longest to cook. Then add some meat slices. Start with one kind at a time. Cook the non-marinated meats first, and end with the marinated varieties to minimize smoke. Arrange the meat pieces on the grill, making sure they're evenly spaced. You can cut large slabs of meat before or after cooking, depending on how you prefer your meats.
When cooking thin slices of meat, like bulgogi, leave them alone for a full minute before you start to flip. This allows the juice to lock in the meat; you’re not meant to move them around like when you’re sauteing.
When you notice the top of your meat is starting to sweat or slightly starts to become charred (only recommended for extremely fatty cuts), you can flip them. Don't be that person at the table who flips their meat more than three times - Koreans firmly believe that grilled meats should be left alone to cook nicely. Otherwise, your juicy cuts of beef, pork, or chicken will become rubbery jerky.
After another minute, check to see if your meat is cooked through. If you see that it needs more time, flip it again a final time. When cooked, the meat has a nice char and it’s time to take the pieces off the grill.
Portion the meat into small plates by using kitchen shears to cut them up. You can cut them directly onto a platter or serve onto individual plates. If there are burnt pieces, you can snip them off at this point, too. If you’re using bone-in meats, you can snip these directly into the bone bowls. It’s best to enjoy K-BBQ as soon as they’re cooked so don’t cook a lot at one time. This also keeps the grill pan from emitting too much smoke.
Continue this process with the rest of the meats; it’s good to have a back up hot or grill plate if it gets too smoky. If you have a large enough grill, you can set aside some meat pieces on the edges to keep warm, and do the same with basically any vegetable.
