Seafood Stock

Crawfish

Crawfish stock is the backbone of dishes like gumbo and étouffée. The goal is not a delicate fish broth, but a deep, shell-driven stock with roasted flavor and strong body.

Ingredients (base ratio)

  • 1–2 lb crawfish (whole, shells and heads)
  • Shells and heads from ~2 lb shrimp (optional but highly recommended for depth)
  • 1 small onion, roughly chopped
  • 2 celery stalks, roughly chopped
  • 2 cloves garlic
  • Water to just cover

Method

Prep

  1. Thaw crawfish and shrimp if frozen.
  2. Start the water boiling, which will reduce pressure cooker time.
  3. Peel shrimp and use shells and heads for the stock. Save meat for another use.
  4. Lightly crush crawfish to expose more surface area.
  5. Toss shrimp and crawfish with a small amount of tomato paste.

Roast

  1. Spread shrimp shells, shrimp heads, and crawfish on a sheet pan and roast at high heat (around 425°F / 220°C) until deeply colored and aromatic, about 15–25 minutes.

Cook

  1. Combine roasted shells with onion, celery, and garlic and place in the pot or pressure cooker.
  2. Add just enough of the boiling water to barely cover.
  3. Pressure cook on high for 8 minutes, then allow natural release, or if using a pot, simmer gently for ~45–60 minutes.

Finish

  1. Strain through a fine mesh and press solids lightly to extract liquid without forcing bitterness.
  2. Simmer uncovered until the stock is concentrated and strongly flavored.
