A cool, bright coastal starter
Crab-stuffed avocados bring together sweet seafood, rich avocado and the sharp lift of lime. They feel festive enough to set out for guests, yet require no stove or oven when you start with fully cooked crab. Serve one filled avocado half per person as a starter, or two halves with a simple salad for a light meal.
The filling is deliberately restrained: a little dressing holds the crab together without hiding its flavor. Finely chopped red onion adds crunch, cilantro adds freshness, and a small amount of chile can bring heat. You can prepare the dressing ahead, but wait to cut and fill the avocados until close to serving so they keep their color and shape.
Choose cooked crab and keep it cold
For four starter portions, use about 8 ounces of fully cooked crabmeat and two ripe avocados. Pasteurized, refrigerated crabmeat or cooked crab picked from its shell can work; check the package to confirm it is ready to eat. If using previously frozen cooked crab, thaw it in the refrigerator rather than on the counter. Keep the crab chilled until you are ready to mix the filling, and follow any storage instructions on its package.
This recipe is a no-cook assembly, not a method for preparing raw seafood. Lime juice brightens the dressing, but citrus curing does not make raw crab or other raw seafood equivalent to cooked seafood. Begin with crab that has already been properly cooked. Use clean hands, utensils and a cutting board, and keep ready-to-eat crab away from any raw seafood and its juices. If the crab has an off odor, looks questionable or has been left unrefrigerated too long, do not use it.
Mix the filling without breaking up the crab
In a bowl, stir together 2 tablespoons of mayonnaise or plain thick yogurt, 1 tablespoon of fresh lime juice, 2 tablespoons of finely diced red onion and 2 tablespoons of chopped cilantro. Add a little finely minced chile if you like, then season lightly with salt and black pepper. Taste the dressing before adding the crab: it should be tangy, but not so tart that it overwhelms the seafood.
Check the cooked crabmeat for any bits of shell, then fold it into the dressing with a spoon or spatula. A few gentle turns are enough. The goal is a filling with visible pieces of crab, not a smooth spread. If it seems dry, add a small spoonful of dressing; if it seems loose, avoid adding more liquid. Cover and refrigerate the filling while you prepare the avocados.
Fill the avocados just before serving
Choose avocados that yield slightly to gentle pressure but are not mushy. Halve them lengthwise, remove the pits and brush or spoon a little of the remaining lime juice over the cut surfaces. If the seed cavities are small, scoop out a little flesh to make room for the filling. You can dice that extra avocado and fold it into the crab, or save it for a side salad.
Set the halves cut-side up on a platter and divide the chilled crab mixture among them. A few cilantro leaves, thin slices of radish or a modest pinch of chile make an attractive finish. If the halves wobble, place each on a bed of shredded lettuce. Offer lime wedges alongside so guests can add more acidity to taste.
Serve promptly, keeping the platter chilled until it goes to the table. For an outdoor meal, set out smaller batches and return the rest to the refrigerator rather than leaving seafood in the heat. Refrigerate leftovers promptly; for the best texture, assemble only as many avocado halves as you expect to eat.
Make it a meal
The stuffed halves pair well with crisp vegetables that contrast with the creamy filling. Try sliced cucumber, a tomato salad or lightly dressed cabbage on the side. Toasted corn tortillas or plain crackers can add crunch without turning the dish into a heavier meal.
For a different flavor balance, swap some cilantro for chopped parsley or add a little finely diced celery. Keep any additions small enough that the cooked crab remains the focus. Whatever variation you choose, treat the lime as a seasoning and the cold, fully cooked crab as the foundation of this no-cook dish.
