Pat's Seafood Stock

Save those shrimp heads and shells. This is exactly what they’re for. A long, slow simmer pulls out all the briny, sweet flavor locked inside and turns kitchen scraps into liquid gold.

The aromatics here are classic Cajun trinity territory: celery and onion form the backbone, with garlic and half a lemon adding brightness that keeps the stock from tasting flat or one-note.

Simmer time is flexible, anywhere from two to eight hours. A shorter simmer gives you a lighter, more delicate stock suited for chowders and light sauces. Go the full eight hours and you get an intensely concentrated base that can stand up to a rich gumbo or bisque.

Keep the heat low after the initial boil. A rolling boil breaks down the proteins too aggressively and clouds the stock. A gentle bubble is what you’re after.

Pro Tips

• Shrimp heads have more flavor than shells alone. If you only have shells, use a generous amount and simmer closer to the full eight hours.
• Strain through a fine-mesh sieve lined with cheesecloth for a crystal-clear stock. One pass through a regular strainer leaves grit.
• Cool the stock quickly by setting the pot in an ice bath before refrigerating. Fast cooling prevents bacterial growth.
• Freeze in ice cube trays or small containers for easy portioning. This stock keeps frozen for up to three months.

Variations

• Roasted shellfish stock: Roast the shrimp heads in the oven until deeply red before simmering for an even richer, more complex flavor.
• Thai-style: Add lemongrass, galangal, and kaffir lime leaves to the pot for a fragrant stock base perfect for tom yum or coconut soups.
