Taste and texture:

This tasty butter sauce is a little spicy, a little sweet, and so creamy and buttery. The chopped onions add a delicious savoury flavour and a little texture to the smooth, melted butter to make this sauce a little thicker. This sauce melts in your mouth with every bite!

Key ingredients and substitutions: 

• Unsalted butter - unsalted butter forms the base of this delicious butter sauce. I recommend using unsalted butter rather than salted butter. If you are dairy free or vegan use a vegan butter instead. 
• Onion - freshly chopped onion helps add delicious flavour and texture to this cajun sauce. 
• Garlic - fresh garlic adds even more savoury flavour to this sauce recipe. 
• Apple cider vinegar - this helps contrast the other flavours in this butter sauce. Instead of apple cider vinegar you can also use lemon juice. 
• Honey - honey adds the perfect amount of sweetness to this sauce. I recommend using raw, unpasteurized honey for the most health benefits. If you are vegan, you can use maple syrup instead. 
• Cajun seasoning - it wouldn't be a cajun sauce without cajun seasoning! You can either make your own cajun seasoning or use a store bought cajun seasoning. Instead of cajun seasoning you can also use creole seasoning too. 

How to make this recipe: 

Step one:

First, in a small saucepan, melt the butter over medium heat on the stovetop.

Step two:

Once the butter is melted turn the heat down to low and add the onion and garlic and simmer for about 5 minutes, until the onion is translucent.

Step three:

Then stir in the cajun seasoning, honey and apple cider vinegar and simmer for few minutes, until the sauce has the thickness or consistency that you prefer.

Step four:

Lastly, remove the pot from the heat and serve!

Recipe tips:

• If you prefer a thicker sauce, allow the sauce to simmer for even longer to thicken even more. 
• Instead of cajun seasoning you can use creole seasoning to turn this into creole butter sauce. 
• You can use any type of onion that you like for this sauce including white onion, yellow onion or sweet onion. 
• I recommend using unsalted butter for this recipe rather than salted butter.
• If you don't have apple cider vinegar you can use another vinegar of your choice such as white vinegar or rice vinegar or lemon juice.
• If you are serving a crowd feel free to double or triple this recipe.

Recipe variations: 

• To make this into a vegan cajun butter sauce: use a vegan butter and maple syrup instead of honey. 
• To make this sauce dairy free and lactose free use a vegan butter.
• If you like a less spicy sauce, decrease the amount of cajun seasoning you add. 
• If you like a sweeter sauce, add a bit more honey. 
• To turn this into lemon cajun butter sauce use lemon juice instead of apple cider vinegar.
