Watermelon doesn’t last long once it’s been cut, and it can quickly turn mushy, dry, or bland. Slicing it into big pieces or tossing it in the freezer are possible solutions, but there’s actually a better way to keep it fresh in your fridge.

Here, we’ll go over the easiest method to store it and help it last for days without losing its texture or flavor. This simple trick works whether you’re cutting up a whole melon or saving leftovers from a summer watermelon drink. We’ll also cover extra tips on picking, prepping, and freezing this fruit the right way. Let’s start.

The best way to store watermelon once it’s cut

Once you’ve sliced into a watermelon, the key to keeping it from turning soft or tasteless is in the way you store it. The trick is to cut the watermelon into small cubes or bite-sized chunks, then transfer them into an airtight container or a zip-top bag with as little air as possible. Vacuum-sealed bags work great if you have them. Otherwise, just press the air out of a good-quality resealable bag.

Then, store it in the refrigerator, ideally at the front, where it’s coldest but not freezing. Eat it within four to five days for the best texture and flavor. After that, the melon starts to lose moisture and can take on a mushy or watery consistency.

Smaller pieces have more surface area exposed, so they chill faster and more evenly, which helps prevent spoilage. Keeping air out of the container also limits oxidation and reduces the chances of off smells, moisture loss, or bacterial growth.

More useful tips for storing watermelon

Aside from using the cut-and-seal method, there are a few more ways to keep watermelon fresh, whether it’s whole or already sliced. Here’s what to know:

Keep the whole watermelon at room temperature if you’re eating it soon: A ripe, uncut watermelon can sit on the counter for a few days. Just keep it out of direct sunlight and eat it within a week.
Refrigerate the whole watermelon for longer storage: If you won’t eat it right away, pop the whole fruit into the fridge. It can last up to two weeks, but the texture may start to change the longer it stays cold.
Wrap large slices tightly: If you’re storing bigger pieces, wrap them in plastic wrap or foil before refrigerating to prevent them from drying out.
Freeze leftover watermelon for drinks or smoothies: If you can’t eat it in time, freeze cubes on a baking sheet until solid, then transfer to a freezer bag. Just know the texture won’t be the same once thawed.
Know the signs of spoilage: Slimy surfaces, sour smells, or visible mold are all signs it’s time to toss it. Watermelon should be firm, juicy, and smell mildly sweet.

With just a few smart habits—like cutting it into smaller chunks and sealing it up tight—you’ll keep your watermelons tasting fresh longer. It’s one of the easiest ways to make sure every bite stays sweet and crisp, just like it should.
