How to make this Cajun butter sauce
Whether you're serving up steak and seafood chicken nuggets, or fries, serving this Cajun butter sauce as a dip provides an incredible depth of flavor that will impress your friends and family.
The ingredients
Butter. The main ingredient in this recipe. Butter’s natural flavor gives this Cajun butter sauce a satisfying richness and luscious texture. But it also has valuable nutritional properties.
Garlic. Besides its health benefits, it also works great as a flavor booster. This ingredient can alone take this dipping sauce one step further. Delivers delicious Cajun flavors.
Onion. I have used red onion, but yellow onion also works well here.
Jalapeno. Cajun sauce is known for its spiciness, and jalapeño is one of its reliable spice sources. Do you have heat tolerance? no worries. You can control the heat by adjusting the amount of seeds and the rib(the white membrane inside the jalapeno).
For instance, remove the seeds on the white membrane if you want to keep your sauce mild. And add the flesh of jalapeño. On the other hand, if you make your sauce with a punch, add along with its seeds and the rib. But make sure to wear a pair of gloves to avoid any skin irritations.
When you want the Cajun butter sauce with no heat but retain all the brilliant flavors, you may substitute jalapeño with the bell pepper.
Cajun seasoning. I have used homemade Cajun seasoning. However, you may use store-bought Cajun seasoning as well.
Flour. The flour helps to thicken the sauce and gives it a creamy consistency that is perfect for dipping or coating foods like meats or vegetables.
The directions
Prepping. Firstly, mince the garlic. Cut the jalapeños and remove the core and the seeds. And chop the jalapeño finely. Reserve the seeds and the rib; you may add them later according to your heat tolerance. Now, set everything aside.
Cooking. Place a pan over medium heat, add butter, and let it melt.
Add minced garlic, chopped onion, jalapeno, and salt, and cook for about two minutes or until the garlic is fragrant.
Then add the flour and stir for a couple of seconds or until the flour is cooked and slightly changes its color.
Remove from the heat. Using the blender, pulse until it turns to a smoother consistency.
How to serve
As a dipping sauce. A good dipping sauce can add flavor and excitement to any dish: goat cheese stuffed mini peppers, spicy green beans.
As a salad dressing. Serve as a salad dressing, that coats the salad ingredients evenly. It is a good enhancer for salad recipes like spicy kale salad.
As a glaze. It perfectly matches up to glaze over seafood recipes like pan-seared salmon, shrimp BBQ, spicy garlic lime chicken, cedar grilled lemon chicken, cedar plank salmon.
How to store?
Refrigerate. Store leftover Cajun butter sauce in an airtight container in the refrigerator for up to five days.
Freezer. This Cajun dipping sauce is a freezer-friendly recipe. Transfer the Cajun butter sauce to a freezer-safe container for up to three months.
To thaw. Let the sauce sit overnight in the refrigerator and serve at room temperature.
Variations
Chili pepper. Swap jalapeno with mild chili pepper varieties like bell pepper or poblano pepper for gentle heat. And habanero or cayenne pepper for intense heat.
Butter. Unsalted butter is mentioned in this recipe; if you are using salted butter, adjust the salt quantity accordingly.
Vegan. For vegan dietary restrictions, opt for vegan butter or plant-based butter.
Tools required
Skillet. A good quality skillet with a heavy bottom ensures even heating.
Measuring tools. A primary tool that every kitchen should have for fuss-free cooking.
