If you need a substitute for blackened seasoning, don’t worry! There are dozens of similar recipes to try. Cajun and creole seasonings use a similar base, producing comparable flavor profiles. Old Bay seasoning also has a similar taste but tends to be saltier. If you don’t have any pre-made spice mixes, you could make a stripped-down version of this recipe with a chili, onion, and garlic powder blend. You could also use homemade taco seasoning—usually a chili powder and cumin mix—for an earthier, more citrusy version. If you don’t mind a sweeter, tangier alternative, you could also use a Canadian classic made with brown sugar and dry mustard: Traeger Blackened Saskatchewan Rub.
