A whole watermelon is a slippery, awkward thing to cut. It rolls. The rind is thick. One wrong slice and you're chasing it across the counter.
Bob from Home Cook Basics has a simple trick that makes it manageable: cut a small flat spot on one side first. The watermelon stops rolling, and every cut after that gets easier. From there you've got two options - wedges for eating right off the rind, or rind-free cubes for fruit salad.
You'll need a sharp chef's knife or serrated bread knife, a stable cutting board, and about 10 minutes start to finish.
Common questions
How do I keep a watermelon from rolling while I cut it?
Slice a thin sliver off one side first to create a flat spot, then rest the melon on that flat face. A stable base is what keeps the knife, and your hand, safe on a round fruit.
What's the easiest way to cut a watermelon into cubes?
Halve it, lay a half cut-side down, slice the rind off following the curve, then cut the flesh into slabs, strips, and finally crosswise into cubes. Taking the rind off first makes uniform cubes much easier.
Should I cut a watermelon into wedges or cubes?
Wedges are fastest and great for eating right off the rind at a cookout. Cubes take a couple more cuts but are better for fruit salad and for storing in the fridge.
