Crab Stuffed Avocados with Kelp.

Creamy, rich avocados stuffed with sweet lump crab meat and umami rich kelp (seaweed!) in a tangy dressing. These stuffed avocados are packed with all the umami-rich flavors of the sea and they make the perfect appetizer (perhaps for your tiny holiday gatherings?), side dish – or even quick lunch alongside some whole grain crackers. Plus, one of the best things about these stuffed avocados is that they are ready in under 10 minutes!

Do you love avocados as much as we do? We add them to everything – sandwiches, salads, power bowls, eggs, toast – and often, straight up sprinkled with salt. Avocados are Lexi’s favorite food – and one of her “first foods” as a baby too. We go through at least two avocados a day in this house. When the ‘cados are running low, mamma starts to panic a bit – just as most people would when they’re low on milk or eggs or bread. It’s not good to be low on avocados in the Rawn household!

You know what else we love? Stufffed avocados. And these Kelp and Crab Stuffed Avocados are probably the best stuffed avocados I have ever had.

The “stuffing” – or the crab salad – is super simple and is made of:

  • Lump crab meat
  • Ready-cut thaw and serve kelp from Atlantic Sea Farms (more on these awesome folks and their kelp — aka seaweed — towards the bottom of this post) – this adds umami flavor, freshness and an awesome texture to the salad
  • Red onion
  • Chopped fresh parsley

And an easy dressing:

  • Mayo
  • White wine vinegar
  • Kosher salt
  • Freshly ground black pepper

Where can I find the ready-cut kelp from Atlantic Sea Farms?

  • Lemon wedges


  • Add lump crab meat to a medium bowl. Using a fork, break up any large crab chunks. Add kelp, red onion and parsley to the bowl. Toss well to combine. 
  • Make dressing by adding mayonnaise, white wine vinegar, salt and black pepper to a small bowl. Whisk to combine. 
  • Add dressing to crab and kelp mixture. Mix to combine. 
  • Place the eight avocado halves on a serving plate. Using a spoon, add crab and kelp mixture to the avocado halves. Top with black pepper. 
  • Serve with lemon wedges. 


  • If preparing this as an appetizer ahead of time, squeeze lemon over the avocado halves so they don’t brown prior to serving.
  • This recipe can also be made as a Kelp, Crab and Avocado salad (versus stuffed into avocado halves). Just prepare as directed, but add diced avocado to the crab and kelp mixture just before serving and toss gently. If you go this route, you can use two avocados instead of four.

About Atlantic Sea Farms (ASF):

Their Mission: Good food should do good. Their kelp is never dried, never dyed, and is grown at home. They are dedicated to making a powerful and positive impact on the health of their customers and oceans by creating craveable and innovative products made from sustainably farmed sea greens, all while expanding opportunities for Maine’s fishing communities.
Atlantic Sea Farms works with 24 partner farmers on the coast of Maine – all of their partners are active members of the working waterfront community, primarily lobstermen, growing kelp in their off-seasons to diversify their incomes and expand opportunities for Maine’s coast. Kelp has a winter growing season, which is countercyclical to the lobster fishery in Maine, which makes kelp aquaculture the perfect opportunity for lobstermen to diversify their incomes in the face of climate change.
And speaking of climate change, the Gulf of Maine is warming faster than 99% of earth’s oceans, which means a continuously volatile coastal economy. With kelp aquaculture, they work with their fisherman farmer network to grow opportunities in a sustainable way, even in the face of warming waters. Fishermen are also particularly well equipped to become kelp farmers – they already have the boats, working knowledge of knot tying, currents, bottom, tides, and storms.
With more coastline than the state of California, and 5500+ lobster license holders in the state of Maine, Atlantic Sea Farms is working to scale up and increase their positive impact for more fishing families along the coast of Maine. ASF gives their partners free high-quality kelp seed at the beginning of the season, and guarantee purchase at harvest. Their partner farmers are their family, neighbors, friends, and the reason they do what we do. Currently, they have a long waitlist of those looking to become an Atlantic Sea Farms partner – pretty incredible!
