Cajun cooking isn’t for the faint of heart. Influenced largely by The Acadians, a group of French immigrants who settled in Canada before migrating to Louisiana, this hearty cuisine is full of robust flavors and big spices. Pairing their cooking with thee indigenous offerings from the land and people native to North America, you get rustic, seafood-heavy, spicy foods that warm your belly and heart. 

To more easily capture the flavor of Cajun cuisine (aside from a roux), a blend of different seasonings can be mixed together to flavor your food the way the locals do. This spice blend is a combination of most seasonings you’ll already have in your pantry. Critical ingredients include the following:

  • Paprika (smoked, plain or hot)
  • Garlic and onion powders
  • Dried herbs like thyme and oregano
  • Cayenne pepper

Once you have these as your base, riff a little to make it your own. I’ve added mustard powder for some zing and a bit of celery seed for a bright and earthy surprise. For a more nuanced spice mix, start with whole mustard seeds and toast it with the celery seeds until fragrant, about 30 seconds. Grind the toasted seeds in the spice grinder before adding them to the blend.

Recipe Notes

General tips: This recipe includes salt. If you’re following a recipe that calls for Cajun spice, be aware of the salt level and adjust accordingly. Or leave the salt out and season to your liking!

Variation: For extra depth of flavor, use 2 tablespoons whole yellow mustard seeds in place of ground mustard. Toast the mustard and celery seeds in a small skillet over medium-high heat until fragrant, about 40 seconds. Grind in a spice grinder and add to the spice mixture.
