Keep it in an airtight container at room temperature and it will last for months.
Notes
I used dried herbs because I find them more convenient and they last longer, but feel free to use fresh herbs if you want to.
If you don’t like or can’t find some of the herbs, just omit them or use any other ingredient instead, although it’s best to follow the recipe just as it is.
I prefer to mix the different ingredients in a bowl because it’s faster and cleaner. However, you could also blend them if you want your poultry seasoning to have a thinner texture.
Feel free to make a big batch of homemade poultry seasoning, as it will last for a really long time.
