How do I know when the roux is the right color?
Stir constantly over medium heat until the roux reaches a light brown color, which develops the nutty flavor characteristic of étouffée. This typically takes 3–5 minutes.
What's the difference between étouffée and gumbo?
Étouffée is a thicker, more concentrated stew served over rice, while gumbo is brothier and often includes okra or filé powder. Both use the holy trinity and shellfish stock but have different consistencies and toppings.
Can I make this ahead?
Yes. Prepare the sauce (steps 2–7) up to 2 days ahead and refrigerate. Reheat gently, then add the shrimp and cook until pink just before serving.
Why is my shrimp tough?
Shrimp overcooks quickly. Cook for only 2–3 minutes, just until pink. Remove from heat immediately; residual heat will finish cooking them gently.
Can I use chicken or andouille sausage instead of shrimp?
Yes. Substitute 1 lb diced cooked andouille sausage or chicken; skip the initial shrimp seasoning step and add the meat to the sauce in step 8 to warm through, reducing cook time to 1–2 minutes.
