Step 1

In a small skillet, combine the sesame seeds, poppy seeds, dried onion, dried garlic, salt, and red pepper flakes (if using).

Step 2

Warm over medium heat, stirring frequently, until the spices are fragrant and the sesame seeds are turning barely golden on the edges, about 5 minutes. Keep an eye on the pan, as the seeds can burn if they are not stirred frequently, especially during the last couple of minutes.

Step 3

Transfer the mix to a small bowl to cool. Store cooled leftover spice blend in a jar at room temperature for up to 1 month.
