How to Roast Sunflower Seeds

Hulled Seeds:

Clean the sunflower seeds. Place in a colander and shake over the sink to remove small debris. Hand pick out any seed covers or other debris.

In Shells:

Place the sunflower seeds in their shells into a bowl. Pour in enough water to cover the seeds. Add 1/3 to 1/2 cup of salt. Leave the sunflower seeds to soak overnight.
-> If in a hurry, simmer the seeds in the salted water for 1 to 2 hours.

Both:

Preheat the oven to 300°F/150°C. Line the baking sheet or baking dish with parchment paper.

Arrange the seeds across the baking sheet in a single layer. Try not to overlap any.

Place in the oven to roast. They need around 30-40 minutes. They can be stirred around gently - if wished - at the 20 minute mark. Remove when they start to appear brown or are clearly dried.

Allow them to cool and store them in an airtight container.
