I spent years hacking a watermelon into uneven wedges that made a mess of the cutting board and my shirt in equal measure. Then someone showed me the grid method, and cutting a watermelon stopped being something I dreaded doing before every summer gathering.
Why This Method Works
- No wedges to individually slice off the rind at the table
- Produces even cubes that store easily in the fridge
- Takes about 5 minutes once you know the pattern
What You’ll Need
- A whole watermelon
- A large, sharp knife
- A cutting board with a groove, or a rimmed baking sheet to catch juice
Step by Step Instructions
Step 1: Trim the Ends
Cut off both ends of the watermelon so it sits flat and doesn’t roll while you’re cutting.
Step 2: Remove the Rind
Stand the watermelon on one flat end and slice the rind away in strips, following the curve of the fruit, until only the pink flesh remains.
Step 3: Slice Into Planks
Lay the watermelon on its side and cut it into thick, even planks.
Step 4: Cut Into Cubes
Stack the planks and cut them into a grid of cubes, running the knife lengthwise and then crosswise.
Step 5: Store or Serve
Transfer the cubes to a large bowl or storage container for the fridge, or serve right away.
Tips
- Work over a rimmed baking sheet to catch the juice, especially with a very ripe watermelon.
- A serrated knife makes trimming the rind easier than a straight edged blade.
What to Serve With This
Cubed watermelon is a natural addition to any summer spread, and blends easily into a watermelon mint cooler if you end up with more than you can eat plain.
FAQs
How long do watermelon cubes keep in the fridge?
About 4 to 5 days in a sealed container, though the texture is best within the first couple of days.
What do I do with the rind?
Some people pickle it, though most just compost it or toss it. It’s edible but has a mild, slightly bitter flavor most people don’t enjoy plain.
Final Thoughts
This method turned watermelon from a chore into something I actually look forward to prepping before a cookout.
Save this one before your next summer gathering.
