In a small bowl, combine 1/4 cup kosher salt, 2 tablespoons garlic powder, 2 tablespoons onion powder, 1 tablespoon smoked paprika, 1 tablespoon freshly ground black pepper, 1 tablespoon dried oregano, and 1 tablespoon dried thyme.
Whisk the spices together until no clumps remain and the blend is uniform.
Transfer the seasoning to an airtight container and seal tightly.
Store the container in a cool, dark place; the blend will stay fresh for up to 6 months.
To use, sprinkle the seasoning on meats, vegetables, popcorn, or stir into soups and sauces to taste.
