In a small mixing bowl, combine the chili powder, ground cumin, paprika, fine sea salt, ground black pepper, garlic powder, onion powder, and dried oregano.
If you enjoy a bit of heat, add a pinch of red pepper flakes to the mix.
Stir the ingredients together until well blended.
Transfer the taco seasoning to an airtight container and store in a cool, dry place for up to 6 months.
