Measure the minced onion, garlic, sesame seeds, poppy seeds, and salt into a small bowl.
Mix together with a fork or small whisk until completely blended.
Use immediately or store at room temperature in an airtight container.
Notes
Dried minced garlic (also known as garlic granules) is very similar in texture to dried, minced onion. I purchase mine on Amazon since it’s hard to locate in grocery stores. You can technically substitute garlic powder, but I highly recommend the garlic granules for best results. None of the other ingredients in this spice blend are powdered, so garlic powder may not blend as well.You can use toasted or regular sesame seeds. Toasted seeds have more flavor and I prefer using them. However, if you’re planning to cook the seasoning (for example, if you use it to make homemade bagels which will ultimately go in the toaster), you might want to use raw seeds so they’re less likely to burn.
