Total Time
6 hours 15 minutes to 8 hours 15 minutes
Yield
4 servings
4 cups seedless watermelon, cut into ¼ to ½-inch thick cubes or slices
1 tablespoon olive oil
1 to 2 teaspoons Tajín seasoning
Pinch of red chili flakes, optional
Step 1: Prepare the Watermelon
Wash the watermelon if needed and cut away the rind. Slice or cube the watermelon into uniform pieces about ¼ to ½ inch thick. Keeping the pieces evenly sized helps them dry at the same rate.
Step 2: Arrange the Watermelon
Line a baking sheet with parchment paper. Arrange the watermelon pieces in a single layer, making sure they do not overlap. Proper spacing allows moisture to evaporate more efficiently during the drying process.
Step 3: Slowly Dry the Watermelon
Preheat your oven to 170°F or the lowest temperature setting available. Place the baking sheet in the oven and allow the watermelon to dry for 6 to 8 hours. Check periodically throughout the drying process. The watermelon is ready when it becomes chewy, concentrated in flavor, and slightly crisp around the edges.
Step 4: Cool the Watermelon
Remove the baking sheet from the oven and allow the dried watermelon pieces to cool completely. Cooling helps develop a firmer texture and enhances the natural sweetness.
Step 5: Add the Spicy Seasoning
Transfer the dried watermelon pieces to a large mixing bowl. Drizzle with olive oil and sprinkle with Tajín seasoning and red chili flakes if using.
Step 6: Toss and Serve
Gently toss the watermelon until every piece is evenly coated with the seasoning mixture. Enjoy immediately or store in an airtight container for later.
For a sweeter and spicier flavor profile, add a small pinch of cayenne pepper along with the Tajín seasoning.
Watermelon contains a high amount of moisture, so drying times can vary depending on the thickness of the slices and the variety of watermelon used.
For extra citrus flavor, add freshly grated lime zest before serving.
Store dried watermelon in an airtight container in the refrigerator for up to 5 days.
