For 16 servings
- prep
Preheat the oven and spread the seeds.
Preheat oven to 350°F (175°C). Spread the shelled watermelon seeds in a single layer on a baking sheet.
- roast · ~10 min
Roast the watermelon seeds.
Roast for 8–10 minutes, stirring halfway through, until the seeds are lightly golden and fragrant. Watch carefully — they can burn quickly. Let cool for 5 minutes on the tray.
TIPLight roasting deepens the flavor dramatically. Don't skip this step. - mix · ~2 min
Grind the seeds into a powder.
Transfer the cooled seeds to a food processor. Pulse in short bursts for 1–2 minutes until they break down into a fine, sandy powder. Scrape down the sides with a spatula.
- mix · ~5 min
Process into a smooth butter.
Add salt and continue processing on high for 4–5 minutes, stopping to scrape down the sides. The mixture will go from powder to a thick paste, then finally release its oils and become creamy. Add oil one teaspoon at a time only if needed to help it blend.
TIPPatience is key — it will look dry before it turns creamy. Keep processing. - mix · ~1 min
Blend in the sweetener and vanilla.
Add honey and vanilla extract. Process for another 30 seconds until fully incorporated and silky smooth. Taste and adjust sweetness if desired.
- serve
Transfer to a jar and store.
Scrape the butter into a clean glass jar, seal tightly, and store in the refrigerator. It will thicken slightly as it cools.
TIPBring to room temperature for 10 minutes before spreading if it becomes too firm in the fridge.
What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Roast the seeds until just fragrant and lightly golden — over-roasting makes the butter bitter.
- 2Process the seeds patiently; the butter will go through a grainy phase before turning silky.
- 3Add oil only if the seeds seem dry; most watermelon seeds have enough natural oils to blend.
- 4For a smoother texture, warm the seeds slightly before processing to help release oils.
- 5Store in the fridge to keep the butter fresh and spreadable for up to 3 weeks.
- 6If the butter hardens in the fridge, let it sit at room temperature for 10 minutes before using.
