First You Make A Roux

One often finds a proper dark roux essential when cooking traditional Cajun food. This is the basis for most gumbos and stews' thick, rich flavor. You may have heard the phrase, "First, you make a roux," when it comes to being instructed on how to make Cajun or Creole dishes.

It's so true, and if you aren't familiar with the process, you will be after reading this post.

This good roux recipe will take you to delicious and satisfying meals like Chicken Gumbo Recipe: Classic Cajun. It's the most famous Cajun dish, resulting in a delightful pot every time. Another gumbo roux recipe is Seafood Gumbo. It's made with a dark Cajun roux, which gives the gumbo extra rich flavor, highlighting the seafood flavors.

But gumbo isn't the only thing we Cajuns like to flavor up in the kitchen with a roux. There's Best Louisiana Rice Dressing, Shrimp Stew With Eggs, and Comforting Cajun Meatball Stew. Oh, what a tempting buffet!

To make these dishes, you must know how to make the perfect batch of roux, and we begin with two ingredients.

Ingredients

The elements are simple. 

  • Cooking oil - a neutral oil, such as vegetable oil, canola oil, or olive oil.
  • All-purpose flour - regular white flour is needed for the right consistency and nutty flavor.

Instructions

First, put some comfortable shoes on or don't wear any. Wrap an apron around you, turn off the TV and your phone, and don't answer the door. Put on some easy-listening music and tell the family and the dog you will be inaccessible for the next half hour. They won't die.

Grab a thick pot like a Dutch oven or cast iron skillet and a long-handled wooden spoon. Or, use a metal roux spoon like I do. It has a slightly slanted flat edge that makes it easy to move the flour and oil around the bottom of the pot. Very comfy!

Now, measure the oil and flour using a 1:1 ratio or equal parts of the ingredients. Add the oil first and let it heat up over low to medium heat before adding the flour. This helps shorten the cooking time by getting the flour off to a good start.

Add the flour to the hot oil and stir-stir-stir, and don't stop! Be careful as you stir to avoid splashing hot roux on yourself. You may want to raise the heat to medium-high heat to speed up the process. Keep stirring and be patient; this is a labor of love.

Notice how the roux begins to thicken and slowly darken. It will give off a distinct nutty aroma. The scent reminds me of Mama preparing meals in our South Louisiana home.

This medium roux is perfect for a chicken stew. But for a gumbo, you're not quite there yet.

Continue the cooking process until the roux is the color of cocoa powder. Now, it's perfect for a Cajun gumbo recipe. 

The sauce can continue to cook and turn the color of dark chocolate.

As it darkens, it becomes a thinner sauce, and the taste is more intense, very fitting for Seafood Gumbo.

Ingredients of ¾ cup each of oil and flour are enough for a chicken gumbo, and using one chicken, 1 cup each of flour and oil is sufficient for a seafood gumbo.

Cooking With Cajun Roux Recipe

After making the roux, add chopped yellow onion, green bell pepper, and celery. This is the Cajun trinity of vegetables used in making many classic dishes of Acadiana.

After adding the vegetables the roux stops getting darker and the vegetables start to cook.

There is a Creole Seasoning Blend made of fresh-cut vegetables prepared ahead of time to cook with in your favorite savory dishes. You can make your own or purchase it from the grocery store.

Hint: 

While stirring, do not allow dark spots to form. This happens when the sauce is burning. If you have a burnt roux, throw it out, clean the pot, and start over. Roux-making takes time and experience, so again, be patient.

Top Tip

Don't stop stirring; never take your eyes off the roux! Remove the pot from the burner and adjust the heat if the sauce is getting too dark too fast. 

Storage

You can make roux ahead of time and store it in the refrigerator in an airtight container for a few weeks or in the freezer for a few months. This works well with large batches.
