Cajun Aioli Ingredients
- Mayonnaise: I have used store-bought mayo, usually from the nearby Costco, in big jars. However, feel free to use homemade mayo, vegan mayo, light mayo, avocado, or olive oil mayo.
- Lemon juice: Brighten up the flavors.
- Fresh garlic and garlic powder: We are combining them because they have different values.
- Smoked paprika: We emphasize smoked paprika, as it accentuates the dip.
- Onion powder: Works as a thickening agent and a flavor enhancer.
- Oregano: Its flavor is magnificent when combined with onion and garlic powders.
- Dijon mustard sauce: It gives a punch and balances the other ingredients.

♨️How To Adjust The Heat Level?
This Cajun aioli sauce has a mild heat, mainly from garlic. You can lower the heat further by reducing the amount of garlic and smoked paprika.
Add a pinch of cayenne pepper to enhance the heat, add minced jalapeno peppers, or use a spicy mustard sauce instead of regular mustard.

Storage & Reheating
Repurpose the leftovers as a dip, spread them on sandwiches, add them to salad dressing, or even throw them into other dishes.
Transfer the Cajun aioli sauce to the refrigerator within an hour of making it for the best results. It can be stored in the fridge for up to a week.
I wouldn't recommend freezing this recipe, as the mayonnaise may separate, and the texture can become crumbly once thawed. However, if you still prefer to freeze it, you can restore its creamy texture by stirring it well just before serving.
