Yes, You Can Eat Watermelon Seeds — Here’s How to Turn Them Into a Crunchy Snack or Topping

Few summer rituals are as satisfying as eating a cold wedge of watermelon over the sink, a little juice running down your wrist. And few are as automatic as spitting out the seeds. If you grew up with a certain kind of playground folklore, you may have swallowed one by accident and briefly wondered whether you planted a watermelon in your stomach.

Good news: You did not. 

“Watermelon seeds are absolutely edible,” says Kristy Del Coro, RDN, LDN. The small white seeds in seedless watermelon are immature seed coats, and they’re perfectly fine to eat along with the fruit. The larger black seeds found in seeded watermelon are edible, too, though they’re tougher when raw and can be a little hard to digest if you eat a lot of them at once; the solution is toasting them. 

“When dried or toasted, they develop a pleasant crunch and a subtle nutty flavor that can add both texture and depth to a wide variety of dishes,” says Isaac Bernal, executive chef of the Representation of Spain to the United Nations.

Are watermelon seeds good for you?

Watermelon seeds are not just edible; they’re genuinely nutritious. According to Del Coro, they’re “a good source of fiber, plant protein, healthy fats, and minerals, especially magnesium, zinc, iron, and phosphorus.” They also contain polyphenols, plant-based antioxidants linked to anti-inflammatory benefits. Nutritionally, she says, watermelon seeds are most similar to pumpkin seeds.

Del Coro suggests using a tablespoon or two of watermelon seeds as a topping, or enjoying about an ounce as a snack. People with seed or watermelon allergies, young children, anyone with swallowing difficulties, or anyone who doesn’t tolerate seeds well digestively may want to skip them or be more cautious.

What’s the best way to eat watermelon seeds?

As mentioned, the white seeds in seedless watermelon can be eaten as is, while the black seeds are edible but better when cleaned, dried, and toasted. (You can also buy hulled watermelon seeds, often sold as watermelon kernels, if you want to skip that step.)

“The biggest tip I would give home cooks is to make sure the seeds are cleaned and completely dry before roasting,” says Phillip Dewayne, chef-owner of Park + Cherry in Memphis. “That helps them toast evenly and develop a richer flavor instead of steaming in the oven.”

To roast them, rinse the seeds well, remove any clinging watermelon flesh, and spread them out to dry completely. Toss with a little olive oil and salt, then spread them in a single layer on a sheet pan. Roast at 325°F for 15 to 20 minutes, stirring halfway through, until crisp and lightly browned. Keep an eye on them during the last few minutes, since smaller seeds may toast more quickly. You can also toast them in a dry skillet over medium heat, stirring often, until they smell nutty.

From there, season them however you like — the seeds are mild in flavor, so they’re happy to take on whatever seasonings you use. Bernal likes extra-virgin olive oil, sea salt, and spices like smoked paprika, za’atar, curry powder, or chile powder. Dewayne reaches for flaky salt, smoked paprika, Aleppo pepper, or cumin. 

How to use roasted watermelon seeds

Once roasted, watermelon seeds can go almost anywhere you’d use pumpkin seeds or sunflower seeds. Sprinkle them over salads, grain bowls, yogurt, roasted vegetables, or chilled soups like gazpacho. 

“They make a great garnish for summer salads because they add texture without overpowering the dish,” says Dewayne. 

Bernal suggests adding them to homemade granola, breads, crackers, and trail mixes. For a more creative route, he says ground watermelon seeds can add texture to pesto, sauces, or even breading for fish or poultry. Del Coro also notes that watermelon seeds can be used in seed butters and flours.

There’s also a small but satisfying sustainability win here. “One of the things I appreciate about watermelon seeds is that they support a more whole-ingredient approach to cooking,” says Dewayne. “Instead of throwing them away, you can turn them into something that adds flavor and crunch to a dish.”

So yes, you can eat watermelon seeds. No, they will not grow in your stomach. With a little heat, salt, and imagination, they might even become your new favorite summer ritual.
