Perfect Classic Gumbo Roux Recipe
Introduction
Gumbo roux is the rich, nutty base that gives classic gumbo its deep, complex flavor. Made by slowly cooking flour and oil until it reaches a dark chocolate brown, this roux adds both thickness and depth to your dish. Mastering this essential technique is key to authentic Louisiana cooking.

Ingredients
- 1 ¼ cup flour
- 1 cup neutral oil (vegetable oil or avocado oil)
Instructions
- Step 1: 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—continue stirring to combine well.
- Step 2: After about 5 minutes, reduce the heat to medium-low. Stir constantly for 30 to 45 minutes until the roux reaches a deep chocolate brown color. Be sure to scrape the bottom and sides of the pan as you stir to prevent burning. Never leave the roux unattended or stop stirring, as it can burn quickly.
- Step 3: Use the roux immediately in your gumbo recipe, or proceed to the next step if storing.
- Step 4: To store, remove the roux from the hot pan to stop the cooking process. Let it cool to room temperature, then place it in an airtight container for later use.
Tips & Variations
- Use a heavy-bottomed pan, like cast iron, to evenly distribute heat and prevent scorching.
- Stir constantly and don’t rush the process—the longer you cook, the deeper the flavor.
- If you want a lighter roux, reduce cooking time and look for a peanut butter color instead of chocolate brown.
- Keep a close eye on the roux’s color changes, as it can move from perfect to burnt very quickly.
Storage
Store cooled roux in an airtight container in the refrigerator for up to 1 month. When ready to use, gently reheat it on low heat while stirring to restore its smooth texture. Avoid microwaving as it can cause uneven heating.

Ingredients
Ingredients
- 1 ¼ cups all-purpose flour
- 1 cup neutral oil (such as vegetable oil or avocado oil)
Instructions
- Mix the roux: In a large deep cast iron skillet or Dutch oven, heat the oil over medium-high heat. Gradually whisk in the flour until no lumps remain. The flour and oil mixture will bubble and foam initially, which is a normal part of the process.
- Stir and cook the roux: After about 5 minutes, reduce the heat to medium-low. Continuously stir the mixture for 30 to 45 minutes, scraping the bottom and sides of the pot frequently. The roux will gradually darken to a deep chocolate brown color. It is crucial not to leave the roux unattended or stop stirring as it can burn quickly.
- Use the roux: If you are preparing gumbo immediately, proceed with your gumbo recipe by adding other ingredients to the roux as directed.
- Store the roux: If not using right away, remove the roux from the heat to prevent overcooking from residual heat. Let it cool completely at room temperature before transferring to an airtight container for storage.
Notes
- Use a heavy-bottomed pan like cast iron or a Dutch oven to ensure even heating and prevent burning.
- Constant stirring is essential to avoid lumps and burning during roux preparation.
- The darker the roux, the richer the flavor, but be careful: it can go from perfectly cooked to burnt quickly.
- Store roux in an airtight container in the refrigerator for up to 1 month; it can also be frozen for longer storage.
- Neutral oils like vegetable or avocado oil are preferred to avoid overpowering flavors.
