Enjoy this seafood pasta salad in two variations: using traditional pasta or cauliflower - both are scrumptious! You'll love the combination of high-protein shrimp and crab with a crunchiness from fresh veggies and a tangy sweetness from the dressing! This salad becomes gluten-free, low-carb, and keto-friendly by substituting cauliflower and using our sugar-free French dressing.

You'll Love This Crab and Shrimp Salad
2 Ways To Make It! You can use pasta or cauliflower florets as a pasta substitute. Both are delicious. This is one of my favorite salads, so I played around with the ingredients until it worked perfectly with cauliflower. 🙂
It's delicious. I love the combination of crab and shrimp as well as the crunchy textures from the fresh veg. Using catalina or French dressing brings the tangy sweet combination.
It's Healthier! Already high in protein and fresh veggies, you can make it even healthier by using cauliflower and sugar-free french dressing. Voila! Now it's a gluten-free, sugar-free, low-carb keto crab salad!
Ingredients
- Pasta Shells or Cauliflower - use medium pasta shells or use fresh cauliflower cut into florets approximately 1" in size.
- Vegetables - you'll use fresh celery, tomato, carrot, and green onion.
- Imitation Crabmeat - If you don't want to use imitation crab meat, be sure to use lump crab meat.
- Shrimp - shrimp should be cooked, shelled, and deveined. Again, medium-sized is best, but you can do what I did and cut the large size in half.
- Sour Cream - use full fat or low fat.
- Mayonnaise - I used avocado oil mayonnaise, but you can use any favorite kind. It can be low fat or full fat.
- French Dressing - make our sugar-free Catalina french for the low carb and keto version. Make in advance and use extra as a salad dressing or marinade later!
- Kosher Salt and Ground Black Pepper
For exact ingredient quantities, please see the recipe card below!
Substitutions and Variations
- You can use all shrimp or all crab meat if you prefer.
- If you don't want to use imitation crab meat, you can substitute lump crab meat.
- Make it spicy with a little hot sauce.
- Use cauliflower in place of pasta. Follow recipe below, but you can microwave fresh cauliflower or frozen cauliflower.
How To Make Seafood Pasta Salad
- Cook the pasta and rinse with cold water. If you're using cauliflower, pre-cook until is crisp tender. Rinse with cold water to stop the cooking.
- Mix all ingredients in a large bowl. Cover and refrigerate for a minimum of 2 hours.
- Adjust salt and pepper to taste, serve.
Serving Suggestions
- Serve with a grilled steak for a tasty surf and turf meal.
- I like serving over lettuce. If you are not following a low-carb keto plan, you can serve over a melon wedge - the two pair really well together.
- Serve on its own for lunch or a light dinner.
- If you are not following a low carb or keto plan, you can serve this with a fresh roll, breadstick, or a biscuit.
