Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

8 oz fettuccine or your favorite pasta

1 tbsp olive oil

1 tbsp butter

8 oz shrimp, peeled and deveined

6 oz lump crab meat (fresh or canned, drained)

3 cloves garlic, minced

1 cup heavy cream

½ cup chicken broth

½ cup grated Parmesan cheese

1–2 tsp Cajun seasoning (adjust to taste)

¼ tsp paprika

Salt & black pepper to taste

Juice of ½ lemon

Fresh parsley, chopped (for garnish)

Directions

Cook the pasta according to the package instructions. Drain and set aside, reserving about ½ cup of pasta water in case the sauce needs loosening later.

In a large skillet over medium heat, warm the olive oil and butter. Add the shrimp, seasoning lightly with Cajun seasoning. Cook for 1–2 minutes on each side until the shrimp turns pink and opaque. Remove the shrimp and set aside.

In the same skillet, add minced garlic and cook for about 30 seconds until fragrant. Pour in the heavy cream and chicken broth, then stir in Cajun seasoning, paprika, salt, and black pepper. Let the sauce simmer gently for 3–4 minutes.

Stir in the Parmesan cheese until it melts completely. Add the crab meat and cooked shrimp back into the skillet. Squeeze in the lemon juice and simmer for another 2–3 minutes to heat everything through.

Toss the cooked pasta into the sauce, stirring gently to coat all the noodles. If the sauce feels too thick, I like to add a splash of the reserved pasta water until it reaches the perfect consistency.

Serve immediately, garnished with chopped fresh parsley. I often enjoy this with crusty bread or a fresh side salad.

Servings and Timing

This recipe serves about 3 to 4 people.
Preparation takes roughly 10 minutes, and cooking time is about 20 minutes, so the entire dish can be ready in under 30 minutes.

Variations

If I want extra heat, I add a pinch of cayenne pepper or a few dashes of hot sauce to the sauce. For a lower sodium version, I use a Cajun seasoning blend without added salt. To lighten the dish, I sometimes swap half of the heavy cream for milk, which keeps it creamy but less rich. If I don’t have crab, cooked scallops or even more shrimp work wonderfully as substitutes.

Storage/Reheating

I store leftovers in an airtight container in the refrigerator for up to 2 days. When reheating, I gently warm the pasta on the stove over low heat, adding a splash of cream or milk to revive the sauce’s creaminess. Avoid microwaving directly, as it can dry out the seafood and sauce.

FAQs

Can I use other types of pasta for this recipe?

Absolutely! While I use fettuccine here, linguine, penne, or even spaghetti work great as they hold the creamy sauce nicely.

Is it possible to make this recipe gluten-free?

Yes, just swap the regular pasta with your favorite gluten-free pasta. The rest of the ingredients are naturally gluten-free.

Can I prepare this dish ahead of time?

You can cook the pasta and sauce separately and combine them just before serving to keep everything fresh and prevent the pasta from becoming mushy.

How spicy is this dish?

It has a mild to medium heat level depending on how much Cajun seasoning you use. I usually start with 1 teaspoon and add more if I want extra spice.

What’s the best way to clean canned crab meat?

I gently drain and rinse the canned crab meat in cold water to remove any excess brine before adding it to the dish.

Conclusion

This Shrimp & Crab Pasta with Creamy Cajun Sauce is one of my favorite go-to seafood dishes when I want something impressive but easy to prepare. The combination of creamy, spicy, and fresh flavors always impresses, and it’s flexible enough for lots of tasty tweaks. Whether for a cozy dinner or entertaining guests, it’s a dish I keep coming back to.
