1. Begin by gathering all your ingredients to keep everything within easy reach. This is my favorite part—getting everything prepped makes the process smooth and enjoyable.
2. In a medium mixing bowl, combine the mayonnaise with the Cajun seasoning. I like to start with a tablespoon and taste as I go — it’s easier to add more spice than to tone it down later.
3. Add the hot sauce, lemon juice, garlic powder, and onion powder. Stir everything together until well incorporated. I find that using a whisk or a sturdy spatula helps blend the seasonings evenly into the mayo.
4. Once mixed, give it a taste. Adjust the seasoning if needed—perhaps a pinch more Cajun spice or a splash more lemon juice for brightness. Remember, flavors develop as it sits, so don’t be afraid to adjust gradually.
5. If you like a little color and freshness, fold in some chopped parsley or chives. It adds a lovely visual appeal and a hint of herbal freshness.
6. Transfer your Cajun Mayo to a clean jar or airtight container. For best flavor, let it sit in the fridge for at least 30 minutes before serving, giving the spices time to meld.

One tip from my own kitchen: I like to make this a day ahead so the flavors can really develop. It’s become my go-to for quick sandwiches or dipping when I’m short on time but craving bold flavor.
