Ingredients

  • 1 ¼ cup flour
  • 1 cup neutral oil (vegetable oil or avocado oil)

Instructions

  1. Step 1: Add the oil to a large, deep cast iron skillet or Dutch oven and heat over medium-high heat. Whisk in the flour until there are no lumps. The flour will bubble and foam at first—continue stirring to combine well.
  2. Step 2: After about 5 minutes, reduce the heat to medium-low. Stir constantly for 30 to 45 minutes, scraping the bottom and sides of the pot as you go. The roux should develop a deep chocolate brown color. Be sure not to leave it unattended or stop stirring, as it can burn quickly.
  3. Step 3: If you are using the roux immediately, proceed with your gumbo recipe as usual.
  4. Step 4: To store the roux for later use, remove it from the heat to stop the cooking process. Let it cool to room temperature, then transfer to an airtight container for storage.

Tips & Variations

  • Use a heavy-bottomed pan like cast iron to ensure even heat distribution and prevent burning.
  • Stir continuously to avoid lumps and scorching—patience is key for perfect roux color and flavor.
  • If you want a lighter roux, reduce cooking time and remove from heat when the color is peanut butter brown rather than dark chocolate.
  • Store roux in the refrigerator for up to 2 weeks or freeze for longer storage.

Storage

Store cooled roux in an airtight container in the refrigerator for up to two weeks. To use, warm gently over low heat before adding to your recipe. For longer storage, freeze the roux in small portions for up to three months. Thaw in the refrigerator before reheating and using.

FAQs

Can I use butter instead of oil to make gumbo roux?

Butter has a lower smoke point and can burn easily, so neutral oil is preferred for gumbo roux. Using oil helps you achieve the deep color without burning.

What if my roux burns—can I fix it?

Unfortunately, burnt roux will taste bitter and can ruin your dish. It’s best to discard and start over rather than try to salvage burnt roux.

Ingredients

  • 1 ¼ cups all-purpose flour
  • 1 cup neutral oil (vegetable oil or avocado oil)

Instructions

  1. Mix: Add the oil to a large deep cast iron skillet or Dutch oven and heat it over medium-high heat. Whisk in the flour until there are no lumps. The flour will bubble and foam at first, so continue to stir to blend evenly.
  2. Stir: After about 5 minutes, reduce the heat to medium-low. Stir the mixture constantly for 30 to 45 minutes until the roux turns a deep chocolate brown color. Make sure to scrape the bottom and sides of the pan while stirring to prevent sticking and burning. Do not leave the roux unattended as it can burn quickly.
  3. Use: If you plan to use the roux immediately for gumbo, proceed with your gumbo recipe as usual once the roux reaches the desired color and consistency.
  4. Store: If you want to save the roux for later use, remove it from the hot pan to stop the cooking process. Let it cool to room temperature, then transfer it to an airtight container for storage.

Notes

  • Using a cast iron skillet or Dutch oven helps distribute heat evenly, reducing the risk of burning.
  • Constant stirring is essential to develop the deep flavor and prevent lumps or burning.
  • The roux color ranges from light brown to dark chocolate; the darker the roux, the richer the flavor but also the less thickening power it has.
  • Store roux in an airtight container in the refrigerator for up to 1 month or freeze for longer storage.
  • Be patient—the slow cooking and stirring process is key to achieving a truly authentic roux.
