Reuben Sandwich

Why This Reuben Sandwich Works

During cooking, the rye bread sits right on the hot skillet with butter on the outside, so the bread slowly crisps while the inside stays soft. The butter melts into the bread and browns on the pan, which is what gives the sandwich that crunchy, almost crackly outside instead of just dry toast.

As the sandwiches sit over medium heat, the Swiss cheese starts to melt from both sides. Cheese under the corned beef and cheese on top of the sauerkraut begin to flow and stretch. That melted cheese works like glue, holding the meat, sauerkraut, and bread together so the sandwich doesn’t fall apart when sliced.

Over a few minutes, the heat also warms the corned beef and sauerkraut all the way through. The sauerkraut dries out a bit more as it heats, so the bread doesn’t get soggy. Russian dressing softens slightly and spreads into the warm meat and cabbage. By the time the bread is golden on both sides, everything inside has settled into one hot, melty stack that stays together in each bite.

Mistakes To Avoid

Using heat that’s too high can scorch the bread while the cheese inside is still firm. The outside turns dark and hard before the corned beef has time to warm through, so the sandwich ends up burnt on the surface and cold in the middle.

Letting the sauerkraut stay very wet makes the sandwich soggy. As it heats, the extra liquid seeps into the bread and thins the dressing, so the bottom slice can turn limp and fall apart when picked up.

Skipping the second slice of cheese on top of the sauerkraut often leads to a loose, messy sandwich. Without that extra layer melting over the filling, the meat and kraut slide out easily and the inside doesn’t hold together when sliced.

Using very thick piles of corned beef in one spot means the center doesn’t heat evenly. The outer layers get hot and a bit tough while the middle stays lukewarm, so each bite has a mix of chewy and cold pieces instead of a soft, warm stack.
