Cajun Seafood Pasta

There’s something about creamy pasta dishes that just feels like a warm hug after a long day. Now, add in a little Southern flair, some spice, and juicy seafood—and suddenly, you’ve got a weeknight dinner that tastes like a restaurant-style splurge.

Where It All Started

This dish first came together for me on a rainy evening when I had shrimp, scallops, and not much else in the fridge. I tossed them with Cajun spices and heavy cream over pasta, and just like that, a go-to comfort meal was born. It’s quick, flexible, and tastes like it took way more effort than it actually did.

A Few Quick Tips Before You Start

• Don’t overcook the shrimp or scallops—they only need a few minutes!

• Fettuccine is a classic choice, but linguine or spaghetti work too.
• If your Cajun seasoning has salt in it, taste before adding extra.

What You’ll Need

Ingredients:

• Shrimp – peeled and deveined
• Scallops – optional but highly recommended
• Fettuccine pasta – or any long pasta
• Heavy cream – for that silky, rich base
• Butter – adds flavor and helps sauté the seafood
• Garlic – always
• Parmesan cheese – freshly grated
• Cajun seasoning – homemade or store-bought
• Salt & black pepper – for balance
• Fresh parsley – a fresh hit of color
• Olive oil – for searing
• Lemon – a squeeze at the end brightens everything

Ingredient Swaps & Variations

• Seafood options: Try crab, lobster, or firm white fish.
• Cream alternatives: Use half-and-half or coconut cream for a lighter/dairy-free version.
• Make it gluten-free: Just swap in GF pasta.
• Add veggies: Sautéed bell peppers or spinach work great.
• Extra heat: Add cayenne or red pepper flakes if you like it fiery.

Let’s Make It: Step-by-Step

1. Cook your pasta according to package directions. Reserve a cup of pasta water, then drain and set aside.
2. Season the seafood with Cajun seasoning, salt, and pepper.
3. Heat olive oil and butter in a large skillet over medium heat. Add shrimp and scallops and cook for 2–3 minutes per side until opaque. Remove and set aside.
4. In the same pan, add more butter if needed and sauté the garlic until fragrant (about 1 minute).
5. Pour in the heavy cream, and bring to a gentle simmer. Stir in Parmesan cheese until melted and smooth.
6. Toss in the pasta, coating well with the sauce. Add seafood back to the pan.
7. Finish with lemon juice and chopped parsley. If needed, loosen the sauce with reserved pasta water.

Serving Ideas

• Serve with crusty bread to scoop up extra sauce.
• Pair with a crisp white wine like Sauvignon Blanc.
• Add a side salad to balance the richness.
• Sprinkle with extra Cajun spice for heat lovers.

Storage & Reheating

Store leftovers in an airtight container for up to 3 days. Reheat gently over low heat, adding a splash of cream or milk to refresh the sauce. Avoid microwaving the seafood too long—it can turn rubbery.

Common Questions

Q: Can I make this ahead of time?
A: You can prep the sauce and seafood ahead, but cook pasta fresh for best texture.

Q: Can I freeze it?
A: Not recommended—cream sauces and seafood don’t freeze well.

Q: How spicy is it?
A: Depends on your Cajun blend! Start mild and adjust as you go.

Q: Can I make this without cream?
A: Sure! Try a roux-based sauce or use coconut milk for a non-dairy twist.
