For 4 servings
Preheat your oven to 325°F (160°C). If using a stovetop, prepare a large, dry skillet over medium heat.
In a medium bowl, combine the watermelon seed kernels, olive oil, smoked paprika, cayenne pepper, garlic powder, and salt. Toss thoroughly until all the seeds are evenly coated with the oil and spices.
**Oven Method:** Spread the seasoned seeds in a single layer on a baking sheet lined with parchment paper. Ensure they are not overcrowded to allow for even roasting.
**Oven Method:** Bake for 5-7 minutes, stirring halfway through, until the seeds are fragrant, lightly golden, and crisp. Watch them closely as they can burn quickly.
**Stovetop Method:** Add the seasoned seeds to the preheated dry skillet. Toast over medium heat for 3-5 minutes, stirring constantly, until they are fragrant, slightly puffed, and golden brown.
Remove the seeds from the oven or skillet and immediately transfer them to a plate or a clean baking sheet to cool completely. This prevents them from overcooking and helps them crisp up.
Once cooled, the seeds will become even crunchier. Serve immediately as a snack, or store for later.
What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1**Even Coating is Key:** Ensure every seed is lightly coated with oil and spices for maximum flavor and even roasting. Use your hands if necessary to mix thoroughly.
- 2**Don't Overcrowd:** Whether using an oven or skillet, spread the seeds in a single layer. Overcrowding will steam them instead of roasting, leading to a less crispy result.
- 3**Watch Closely:** Watermelon seeds are small and can go from perfectly toasted to burnt very quickly. Stay near the oven or stovetop and stir frequently, especially during the last few minutes.
- 4**Cool Completely:** Allow the seeds to cool fully at room temperature before storing or serving. This step is crucial for achieving the best crunchy texture.
