Preheat your air fryer: Set to 300°F (150°C).
A lower temperature prevents burning delicate seeds.
Toast the sesame seeds: Spread sesame seeds in a thin, even layer in the air fryer basket or on a small piece of foil. Air fry for 3–5 minutes, shaking halfway. Pull them as soon as they turn lightly golden and smell nutty.
Cool completely: Transfer the seeds to a plate to cool for 5 minutes.
This stops carryover cooking and keeps them crisp.
Combine the herbs: In a small bowl, add dried thyme, oregano, and sumac. If using cumin, coriander, or marjoram, add them now.
Mix and season: Stir in the cooled sesame seeds and start with 1/2 teaspoon sea salt. Taste and add more salt if needed.
You want a bright, savory balance without overshadowing the sumac.
Optional oil finish: For a slightly moist, clingy blend, drizzle in 1–2 teaspoons olive oil and stir well. This is great for breads and dips.
Store: Transfer to a small airtight jar. Label and date it.
Use within 4–6 weeks for the freshest flavor.
