Ingredients (with Helpful Notes)

Just a handful of ingredients — each one pulling its weight:
- Watermelon: Go for a ripe one that’s deeply red inside and heavy for its size. You want it firm enough to cube cleanly without falling apart.
- Feta cheese: Buy the block, not the tub of pre-crumbled. Block feta is noticeably creamier and more flavorful — worth the extra step of crumbling it yourself.
- Fresh mint: Non-negotiable. Fresh mint lifts the whole salad with a cool, herby brightness that dried mint simply cannot replicate.
- Red onion: Slice it paper-thin. A little goes a long way — you want a subtle sharpness, not a mouthful of raw onion.
- Balsamic glaze (optional): A drizzle right before serving adds a sweet, tangy depth. Skip it if you want to keep things super simple, but it’s a nice touch.
Directions
Add the cubed watermelon, thinly sliced red onion, crumbled feta, and torn mint leaves to a large bowl. Gently toss everything together until combined. If using balsamic glaze, drizzle it over just before serving. Serve immediately, nice and cold.

Tips for the Best Results
Pick a great watermelon: A yellow ground spot and a hollow thump when you tap it are good signs. Heavy for its size usually means extra juicy. Starting with a cold watermelon keeps the whole salad crisp and refreshing.
Always use block feta: You get bigger, creamier crumbles and far better flavor than anything pre-packaged.
Add the feta last: Fold it in gently right before serving so the pieces stay intact rather than breaking down into the salad.
Go thin on the onion: A mandoline or a sharp knife and some patience make all the difference — thin slices blend in beautifully rather than taking over.
Use only fresh mint: Dried mint will make the salad taste flat. Fresh mint is what gives this salad its signature brightness.
Hold the glaze until the last second: Drizzling balsamic too early pulls extra liquid out of the watermelon and makes the whole thing watery fast.
Storage
- Best eaten right away: The flavor and texture are at their peak the moment it’s assembled.
- Leftovers keep for 1–2 days: Store in an airtight container in the refrigerator, but know it will get juicier as it sits.
- Expect some liquid: Watermelon naturally releases moisture over time — this is normal, not a sign anything went wrong.
- Prepping ahead: You can cube the watermelon and slice the onion a few hours ahead. Keep everything separate and toss it together right before serving for the best results.

Notes
