The right lettuce for preventing soggy buns

For especially juicy burgers, opt for sturdy iceberg lettuce to help prevent juice absorption while adding a satisfying crunch to your sandwich. Romaine and butter lettuce are also good choices, but remember that while butter lettuce can easily wrap around the bun, it doesn't offer the same crispness as iceberg or romaine.
In addition to lettuce, there are several strategies to keep your burger easy to handle. Instead of placing a slice of cheese directly on the patty, melt a slice of cheese—like American or cheddar—onto the inside of each bun. This, along with the lettuce, will create a moisture-resistant barrier that helps keep the burger's juices from soaking into the bun. Position drier toppings closer to the top and bottom buns, while placing juicier ingredients, such as tomato slices, in the center.
If you have a bit of extra time, consider toasting the buns as well. Browning them in butter or mayo will make them crispy enough to handle a bit more moisture. Even with all these precautions, it's best to enjoy your assembled burgers right after making them. The longer they sit, the more likely those juices are to seep into the bun.
