Instructions

1. Step 1: In a heavy-bottomed pot over medium heat, melt 4 tbsp unsalted butter. Whisk in 4 tbsp all-purpose flour and cook, stirring constantly, for 5-7 minutes until the roux turns a deep golden brown and smells nutty.
2. Step 2: Add 1 large diced yellow onion, 1 diced green bell pepper, and 2 diced celery stalks to the roux. Sauté for 6 minutes until vegetables are softened and fragrant.
3. Step 3: Stir in 3 minced garlic cloves, 2 tsp Cajun seasoning, 1/4 tsp cayenne pepper, and 2 tbsp tomato paste. Cook for 2 minutes until the mixture darkens and the tomato paste deepens in color.
