Most recipes involving iceberg lettuce are fairly straightforward. However, preparing it can still be tedious, especially if you’re cooking for a large group. Even if you’re just separating leaves for burgers, the prep time really adds up. That’s where this hack comes in: Use it to core your lettuce quickly and without dirtying a knife.
Core Iceberg Lettuce in Seconds
It’s not every day that you’re instructed to smack your food against the countertop, so have a little fun with this hack. Here’s what to do: First, make sure the core of the iceberg lettuce is facing down. Holding the head of lettuce in two hands, slam it down on a hard surface, such as a countertop or cutting board. (One hard whack is likely all you need.) Next, turn it over and twist out the core — it should dislodge with ease. The impact breaks the core free from the surrounding leaves, allowing you to remove it for hassle-free chopping.
This hack works only with iceberg lettuce — not romaine or other common types of lettuce — because it relies on the iceberg’s tightly packed head and brittle core. While cabbage has a similar round shape, its core is far too thick and dense for this trick to be effective.

How To Crisp Iceberg Lettuce
If your iceberg lettuce lingered in the crisper drawer a little too long and now feels soft and wilted, you can revive it in just 15 minutes. After removing the core, place the leaves in a large bowl filled with ice water. Allow the lettuce to soak for 15 to 30 minutes, then drain the cold water. Your greens should now be crisp and crunchy. This hack works because of osmosis — the dehydrated plant cells soak up water and swell, bringing back that signature crunch. Don’t attempt this trick with iceberg lettuce that has brown spots, a slimy texture, mold, or a foul odor. It’s not just wilted — it has spoiled and should be discarded.
