Making a Roux

  1. The fat you use to make a roux greatly impacts its flavor. Using bacon drippings creates a smoky, salty base for the dish you're making. Butter adds richness, and shortening and other types of oil tend to create a lighter flavor. Use the fat recommended in the recipe you're using, or if it's not specified, consider these options: [1]
    • Use bacon or pork drippings to make a roux you'll be using for gumbo or another dish that will have smoky elements like sausage.
    • Use butter to make a roux you'll be using for a creamy soup, such as a chowder. This is also a good choice if you're making a roux for macaroni and cheese. [2]
    • Shortening makes a good roux base for lighter gratin dishes, since it doesn't have an overwhelming flavor.

    Use a cast iron skillet or another heavy frying pan. Place the pan over medium heat and add the fat. Let the fat heat until it has just melted. If you're using oil, let it heat for just about 2 minutes. [3]

    Place the flour in the skillet with the fat. Use a whisk to begin stirring the mixture constantly. Use the whisk to break up any lumps in the flour and distribute it evenly through the melted fat. [4]
    • If you want a thicker, past-like roux, add an extra 1/4 cup of flour.
    • For a thinner, more liquid roux, reduce the flour by 1/4 cup.

    Continue whisking the roux constantly while it cooks. The mixture will begin to thin and darken after several minutes. Continue cooking it until it has the color and consistency you need for your recipe. [5]
    • Some recipes call for a blond roux. In a blond roux, the roux mixture turns to a light golden color and has a mild flavor. It's usually ready after about 8 minutes. [6]
    • You might see a recipe that calls for a dark roux, also called a chocolate roux. It can take about 60 minutes to achieve this color. Some people find it easier to start the roux on the stove and finish cooking it an over heated to 325 degrees. [7]

    When the roux has reached the color and texture you want, remove it from heat. It's now ready for you to use in the recipe you're following.

    If you want to use the roux later, place it in a food storage container and keep it covered in the refrigerator. It will harden as it cools, but it will melt when you add heat. You can scoop out as much as you need on a recipe-by-recipe basis. [8]

Using a Roux

  1. Roux are an important element of Cajun cooking. Gumbo, a classic Cajun dish, is frequently thickened with blonde or dark roux, depending on the recipe. Make a roux and add ingredients like okra, peppers, sausage, chicken, shrimp, and chicken stock for a delicious dish. [9]
  2. Gratin dishes like potato, cauliflower or tomato gratin have a creamy, cheesy sauce that is built from blonde roux. The roux is thinned with milk and poured over vegetables, then topped with plenty of cheese. [10]
  3. Making macaroni and cheese from scratch is as easy as creating a roux, thinning it with milk, pouring it over cooked noodles and topping with a mix of cheeses. [11]
  4. This French sauce is the foundation of many pasta dishes. [12]

    I thought a roux was equal parts fat and flour by weight, not by volume?

    Community Answer
    Yes, a roux is equal parts fat and flour by weight. It's used as a thickening agent for making continental sauces and gravies.
  • Question
    If using butter and flour to make a roux, should the butter be salted or unsalted?
    07292400
    Community Answer
    Use unsalted butter for your mac and cheese, because the cheese sauce is already very salty with all of the seasons that you have combined into it, including the noodles.

      Tips

      • If you see any black speckles in the roux, that means it's burned. You may want to start over, otherwise it may taste funny.
      • Roux is usually fairly tasteless. The darker it is the more of a smoky flavor it gets.
      • If the roux starts smoking, it's burning. You should notice a consistency change as soon as it starts burning as it will start to firm up very quickly and will start sticking to the pan. Don't cook it past the color of dark chocolate.

      Warnings

      • If you're using a nonstick pan, don't use a metal utensil to stir the roux. It will scratch off the nonstick coating and ruin your pan.
      • Be very careful not to get any hot roux on you. It will leave third degree burns, and stick until it cools.

      About this article

      Article Summary X

      A roux is a mixture of equal parts fat and flour. You can add a roux to a sauce or soup to improve the flavor and thicken the texture of the dish. To make a roux, first choose the fat you’d like to use, like butter, bacon fat, pork drippings, margarine, or shortening. Heat the fat in a nonstick skillet over medium heat until it melts. Then, add an equal amount of all-purpose flour. Whisk the flour into the fat until the texture and color become uniform. How long you cook the roux depends on the color of the roux required for your recipe. Cook the roux for 2-5 minutes to make a white roux, which will thicken your dish without adding a lot of flavor. For a blond roux, cook the roux for 6-10 minutes, or until it's a light brown color. A blond roux will add a toasty flavor to your food. Cook the roux for 15-30 minutes if you’re looking for a medium-brown roux, which has a hearty flavor that’s ideal for gumbo or soup. For a dark roux with a deep, coffee-like flavor, heat the roux for 35-45 minutes. When the roux is done, add it to the dish you’re cooking. You can store any unused roux in the fridge for up to 1 week. If you want to learn how to use your roux when it's finished, keep reading the article!
