I generally don’t add salt to my seasoning mixes; instead I add it separately when cooking. A recipe that specifies a commercial blend assumes it has salt, so adjust accordingly. Be sure to use garlic powder and onion powder, not the salt form of either.
2 teaspoons cayenne, red chili flakes or a combination
2 teaspoons dried oregano
2 teaspoons dried thyme
2 teaspoons onion powder
1 ½ tablespoons paprika
1 teaspoon garlic powder
Combine all the herbs together. If not using immediately, store in an air-tight jar.
