Ingredient Overview

- Watermelon seeds: From one whole watermelon, you’ll have a good amount, but you can easily adjust this recipe.
- Olive oil: Just a touch to coat the seeds, you could substitute with another neutral oil like avocado.
- Salt: Fine sea salt or Himalayan pink salt enhances the nutty flavor. Experiment with flavored or smoked salts, too.
Step-by-Step Instructions
Step 1: Preheat and Prep
Preheat your oven to 375°F (190°C). Rinse the watermelon seeds to remove any remaining watermelon flesh. Pat them completely dry with a clean kitchen towel or paper towels. This helps them roast evenly.
Step 2: Oil and Season
Place the dried seeds in a medium bowl and drizzle with olive oil, just enough to coat each seed. Sprinkle with salt, about 1/2 teaspoon per cup of seeds. You can adjust salt to your taste.
Step 3: Roast
Spread the seasoned watermelon seeds in a single layer on a baking sheet lined with parchment paper. Bake for 15-20 minutes, keeping a close eye on them. The seeds will turn golden brown when they’re roasted to perfection.
Step 4: Cool and Enjoy
Remove the baking sheet from the oven and let the seeds cool completely on the pan. Once cool, they will crisp up further. Enjoy the toasted watermelon seeds as a snack or sprinkle them on salads, soups, or desserts for an added crunch.
Pro Tips
