My aunt’s crab salad recipe is zesty, light, and refreshing—made for summer, especially with crispy tostones on the side.

Crab Salad Recipe
I was just with my aunt in Florida and finally watched her make her Crab Salad so I could get the measurements right. She starts by slicing a red or yellow onion into thin strips and soaking them in warm salted water to mellow the bite. Then, she adds a colorful mix of red, yellow, and orange bell peppers, loads of fresh lime juice, plenty of chopped cilantro, some good olive oil, and simple seasoning. She usually serves it with tostones (which I make in the air fryer) for lunch and we love it, so I’m excited to share it with you!

Ingredients You’ll Need
Here’s what you need for this easy crab salad recipe. See the recipe card below for the exact measurements.
- Onion: Slice a red or yellow onion into thin strips.
- Bell Peppers: Use a combination of red, yellow, and orange to make it more colorful.
- Flake-style Imitation Crab is much more affordable than fresh lump crab, but either will work. Imitation crab primarily consists of Alaskan pollock.
- Limes: Marinating the salad in lime juice mellows the onion’s pungency and imparts the dish with a tart, bright flavor.
- Cilantro for freshness
- Olive Oil balances the lime juice.
- Salt and Pepper season the salad.
How to Make Crab Salad
While the onions soak in water, you can prep the bell peppers, cilantro, and lime juice. Then, just combine everything and refrigerate. See the recipe card at the bottom for printable directions.



- Soak the Onions to Mellow the Taste: Put the sliced onions and salt in a large bowl and press the salt into the onions with your hands. Cover the onions with warm water and the juice of half a lime. Let it sit for 15 to 20 minutes to mellow the onion flavor. Drain and rinse the onions under cold water.
- Mix Everything: Cut the bell peppers and cilantro and juice the remaining limes. Add all to a bowl with the olive oil, cilantro, remaining salt, black pepper, and onions.
- Marinate the crab salad for a few hours or overnight. Taste and add more salt if needed.
Variations
- Seafood: Use lump crab or cooked shrimp
- Don’t like cilantro? Skip it or try it with another herb, like chives or parsley.

Serving Suggestions
Serve this cold imitation crab salad recipe as an appetizer at a party or as a main dish for dinner.
- My aunt always eats it with crispy, golden tostones, which takes it to another level, but I made my air fryer tostones to keep it light.
- Tortilla chips work great, too, or just eat it with a spoon!
Storage
This imitation crab salad will last up to 4 days in the fridge. Since the flavor improves the longer it marinates, it’s excellent for leftovers. It’s a great quick lunch since you can eat it cold.
