Ingredients You’ll Need

The beauty of Creamy Cajun Shrimp Pasta is in its approachable, simple ingredients. Every component adds a layer of flavor, from the sweet snap of shrimp to the savory depth of Cajun spices and the richness of cream. Here’s what you’ll need, with a few tips for bringing out the best in each.

Shrimp (150g): Pick fresh or properly thawed frozen shrimp for juicy, flavorful bites in every forkful.
Lemon juice (1 tsp): A squeeze of citrus brightens the shrimp and cuts through the richness of the sauce.
Smoked paprika (1 tsp + ½ tsp): Gives smokiness and depth, layer it both in the shrimp and the creamy sauce for extra flavor.
Cajun seasoning (1 ½ tsp + 2-3 tsp for sauce): The heart and soul of the recipe, lending complex heat and zest—use your favorite blend or homemade.
Olive oil (2 tsp): Helps sear the shrimp and provides a subtle fruity base for the sauce.
Tagliatelle (200g): Wide, silky noodles that cling to the sauce beautifully—though any pasta you love will work.
Water & salt: Salty pasta water seasons the noodles and can be used to loosen the sauce later.
Unsalted butter (1 tbsp): Adds beautiful silkiness and a touch of sweetness to the sauteed veggies.
Garlic (2-3 cloves, minced): For that irresistible aroma and punchy backbone in the sauce.
Yellow onion (½, diced, about 40g): Gives sweetness and a mellow bite.
Red bell pepper (½, diced, about 80g): Adds color, crunch, and natural sweetness.
Concentrated tomato paste (2 tsp): Intensifies the overall savory flavor and adds beautiful color.
Heavy cooking cream (1 cup/250 ml): Creates that signature luscious, velvety sauce you’ll want to scoop up with bread.
Red pepper flakes (1 tsp): Optional but highly recommended for an extra spark of heat—adjust to your liking.
Dried parsley (1 tsp): Brings herbal freshness and color to the mix.
Parmesan, freshly grated (½ cup + extra to serve): Melty, nutty, and salty, it ties everything together.
Fresh basil or parsley, chopped (1 tbsp + more to garnish): Scattered over the top for freshness and vibrant presentation.
Salt (to taste): Taste as you go, especially after adding cheese which brings its own saltiness.

How to Make Creamy Cajun Shrimp Pasta

Step 1: Prepare the Shrimp

Kick things off by prepping your shrimp. If you’re working with fresh ones, peel them, remove the tails (if preferred), and devein thoroughly. Frozen shrimp should be fully thawed and dried with a paper towel—excess moisture can quickly ruin a perfect sear! Get everything ready so that when it’s time to cook, you’re working with the freshest, plumpest shrimp possible.

Step 2: Season with Cajun Magic

In a bowl, toss the cleaned shrimp with Cajun seasoning, smoked paprika, and lemon juice. Let these marinate for 5 to 10 minutes, allowing the spices to seep in and the citrus to gently tenderize and brighten the shrimp. This brief rest makes all the difference for bold, vibrant flavor!

Step 3: Sear the Shrimp

Heat up your olive oil in a medium-sized, heavy-bottomed pan over medium-high heat. Add the shrimp in a single layer—don’t crowd them. Cook for 2 to 3 minutes per side, flipping just once, until they turn golden brown and develop a caramelized crust. Remove them from the pan right away to prevent overcooking and set aside.

Step 4: Cook the Tagliatelle

Bring a large pot of water to a boil and generously salt it (about a tablespoon). Drop in the tagliatelle and cook it until it’s just al dente according to package instructions. Remember to reserve about a cup of that starchy pasta water before draining—the secret weapon to a perfect sauce!

Step 5: Saute the Aromatics

Back in the same pan you used for the shrimp, melt the butter. Scrape up any flavorful bits left from the shrimp, then toss in the minced garlic. Saute for about a minute until aromatic, then throw in your diced onion and red bell pepper. Let them cook for 3 to 4 minutes, stirring, until they become slightly soft and sweet.

Step 6: Build the Base

Stir in the concentrated tomato paste, then add a quick splash of water to help loosen things up. This move mellows the tomato and allows all those deep flavors to meld.

Step 7: Make It Creamy

Reduce the heat to medium-low and pour in the heavy cream. Sprinkle in the remaining Cajun seasoning, dried parsley, and smoked paprika, stirring well. Let it simmer for a few minutes to thicken slightly. Now, lower the heat and stir in the freshly grated Parmesan. Taste your luxurious sauce and adjust salt as needed.

Step 8: Toss Everything Together

Add the cooked tagliatelle and shrimp back into the pan, along with chopped fresh basil or parsley. Pour in half to a full cup of reserved pasta water, a little at a time, stirring until the sauce reaches your perfect level of creaminess. Turn off the heat—the sauce will thicken as it stands, so don’t let it sit on the stove for too long!

Step 9: Finish and Serve

Spoon the finished Creamy Cajun Shrimp Pasta into your favorite serving dish. Garnish with a shower of extra fresh basil leaves and another sprinkle of Parmesan. This is the moment you’ve been waiting for—dive in and enjoy, especially with some warm garlic bread for soaking up every drop.

Garnishes

For maximum wow-factor, always finish Creamy Cajun Shrimp Pasta with a flourish of freshly chopped basil or parsley and a snowfall of extra grated Parmesan. The herbs keep each bite fresh, and the cheese amps up that savory, creamy finish. If you want a bit more heat, a few extra red pepper flakes on top never hurt!

Side Dishes

This dish is plenty satisfying on its own, but a crisp green salad with a citrusy vinaigrette (think arugula, spinach, or mixed greens) brings lovely balance. And of course, classic garlic bread or warm focaccia are perfect for scooping up all that extra Cajun cream sauce. If you’re feeling fancy, roasted asparagus or simple sautéed green beans fit right in, too.

Creative Ways to Present

Try serving Creamy Cajun Shrimp Pasta in shallow bowls for a rustic, bistro-style vibe, or plate it family-style on a big platter for sharing. A sprinkle of microgreens, a lemon wedge on the side, or even a drizzle of herby olive oil around the rim can really elevate the look. For a fun twist, divide into ramekins and top with a bit more cheese, then broil until bubbly for a gratin-inspired twist.

Make Ahead and Storage

Storing Leftovers

Leftover Creamy Cajun Shrimp Pasta keeps surprisingly well for a day or two. Allow it to cool before transferring to an airtight container and stash in the fridge. The flavors meld and deepen, making your second round just as enjoyable. Keep garnishes separate for the freshest taste.

Freezing

While you technically can freeze Creamy Cajun Shrimp Pasta, creamy sauces sometimes break or become grainy after thawing. If you must freeze, do so in single portions, and expect a slightly different texture when reheated. For best results, enjoy fresh or only refrigerate for short periods.

Reheating

Gently reheat leftovers in a pan over low heat, adding a splash or two of milk, cream, or pasta water to loosen the sauce. Microwave works in a pinch, but take care not to overcook the shrimp. Stir frequently and stop as soon as it’s hot—this maintains the creaminess and prevents the sauce from separating.

FAQs

Can I use a different pasta shape for Creamy Cajun Shrimp Pasta?

Absolutely! Tagliatelle is classic for its ability to hold the sauce, but fettuccine, linguine, or even penne work beautifully. Just be sure to cook your chosen pasta until al dente for the best texture.

How spicy is this Creamy Cajun Shrimp Pasta?

The heat level depends on your Cajun seasoning and whether you add extra red pepper flakes. For a milder dish, use less Cajun and skip the extra flakes, or for more of a kick, feel free to increase them. It’s easy to adjust to your preference!

Can I substitute the shrimp with another protein?

Certainly! Sliced grilled chicken, seared scallops, or even smoky andouille sausage make wonderful alternatives. For a vegetarian twist, swap in sautéed mushrooms or your favorite veggies.

What’s the best way to get a creamy, smooth sauce?

Use heavy cream for the richest result, and always stir in the Parmesan off the heat to prevent curdling. Adding pasta water slowly allows you to control the consistency without thinning out the flavor.

Is it necessary to use freshly grated Parmesan?

Freshly grated Parmesan melts more smoothly and brings unbeatable flavor, but if you’re in a pinch, pre-grated will do. Try to avoid the powdered kind in a can, as it doesn’t melt properly in creamy sauces.

Final Thoughts

If you’re craving a dinner that feels like a warm, spicy hug, Creamy Cajun Shrimp Pasta is your ticket. Each bite is decadent yet lively, packed with comforting flavors and ultra-satisfying. Give it a go—you might just find yourself reaching for this recipe every time you want to impress, indulge, or simply treat yourself to something truly special.
