- Herbs & Spices: Black peppercorns, fresh parsley, and thyme sprigs round out the ingredients for this crab stock recipe.

How to Make Crab Stock
Follow these simple steps to create your own crab stock.
Step 1: Roast your Shells
Preheat oven to 425 degrees. Grease a large baking sheet with the oil. Cover the crab shells and carcasses evenly with the tomato paste. The easiest way to do this is to just get messy and use your hands. Don’t worry they won’t pinch.
Once you’ve got an even coat on the shells, wash your hands and pop them in the oven. Bake the shells for 10-12 mins. It’s important not to let them burn. If you do your stock will be really bitter and unusable.


Step 2: Toss in a Pot
Once your roasted shells are done, take them out and add them to a large stock pot. Toss in the chopped vegetables, herbs, and peppercorns. Fill the pot with cold water, 2-3 inches over the ingredients.
Adjust the heat so the pot bubbles lightly without boiling. If you let it boil your stock will come out a bit murky. We want a nice clear stock.
For the first half hour or so you’ll get some scummy bubbles foaming at the top. Use a serving spoon or ladle to remove the scrum. Simmer uncovered, without stirring for 6 hours.
Step 3: Strain the Crab Stock
Remove the pot from heat and discard any large pieces of crabs. Set a sieve over a large bowl and strain your crabby liquid. For extra clarity repeat this process or a couple times. You could use a cheesecloth in addition to the sieve for top notch clarity.

Step 4: Transfer & Store Crab Stock
Once the crab stock has cooled, transfer it to airtight containers. It will keep well in the refrigerater for up to a week. Enjoy!
Freezing Crab Stock
Or you can freeze the stock for later use. Just be sure to let the stock cool completely before transferring it to an airtight container or freezer bag.
Your crab stock should be pretty flavorful for up to 3 months. It’ll be fine to use after 3 months, it just won’t be as potent or flavorful.
I also like to pour some of my crab stock into popsicle molds and freeze them that way. You don’t have to thaw out an entire container when you just want a little flavor bomb for a sauce, soup, or whatever.

Crabbing on the Oregon Coast
We love making this stock recipe, along with many other crab recipes. Living in the PNW we are blessed with a great bounty of Dungeness crabs every year.
Getting out on the water and catching them ourselves is one of our favorite yearly traditions. It’s super simple and so very fulfilling. Nothing beats bringing home a cooler full of Dungeness crabs.
We go out of Wheeler, OR. The marina there is fantastic. They rent skiffs, bait, and crab rings. A one stop shop for everything you need to catch those crustaceans. Heres a link to their website. Call ahead for reservations.
Genius idea! I always wondered if there was a way to make use of the leftover crab parts and this is super tasty. The color is so beautiful too. Bravo!!
Thanks Eric!
