Ingredients

Shrimp: The star of this dish, shrimp add a naturally sweet and juicy flavor that pairs beautifully with the heat of Cajun seasoning. I always go for medium to large shrimp, deveined and peeled.

Pasta: Rotini or penne work wonderfully because the ridges trap the creamy sauce so well. Use your favorite pasta, but make sure it holds sauce nicely.

Heavy Cream: This is the base of the creamy sauce. It softens the spice of the Cajun seasoning and delivers a luscious texture.

Cajun Seasoning: Adds smoky, spicy, and savory notes. You can adjust the amount depending on your heat preference.

Garlic: Fresh minced garlic infuses the sauce with a savory kick and aromatic depth.

Parmesan Cheese: Brings salty, umami-rich flavor and helps thicken the sauce.

Olive Oil and Butter: Olive oil helps sear the shrimp while butter adds richness to the final sauce.

Salt and Pepper: Essential for seasoning the shrimp and the sauce.

Parsley (optional): For a pop of color and freshness before serving.

How to Make Creamy Cajun Shrimp Pasta

Step 1: Season and Sear the Shrimp

Start by seasoning your shrimp generously with Cajun seasoning. Heat olive oil in a large skillet over medium-high heat and sear the shrimp for about 1-2 minutes per side until they’re just cooked through. Remove them and set aside.

Step 2: Build the Creamy Cajun Sauce

In the same skillet, melt butter and add minced garlic, stirring just until fragrant. Pour in the heavy cream and bring it to a gentle simmer. Stir in more Cajun seasoning and grated Parmesan cheese. Let it simmer a few minutes until the sauce thickens slightly.

Step 3: Cook the Pasta

While the sauce simmers, cook your pasta according to the package instructions until al dente. Reserve about half a cup of pasta water before draining.

Step 4: Combine Everything

Add the cooked pasta to the skillet with the sauce, tossing gently to coat. If the sauce is too thick, add a splash of reserved pasta water until it reaches your desired consistency. Return the shrimp to the skillet and gently fold everything together.

Step 5: Garnish and Serve

Top with freshly chopped parsley and a sprinkle of extra Parmesan if desired. Serve hot and enjoy every creamy, spicy bite.

Recipe Variations and Possible Substitutions

If you’re looking to tweak this Creamy Cajun Shrimp Pasta, there are plenty of delicious directions you can go. Swap the shrimp for chicken breast or smoked sausage for a different protein twist. For a vegetarian option, mushrooms or zucchini are great substitutes that still soak up the bold Cajun flavor.

Don’t have heavy cream on hand? Use half-and-half or even coconut milk for a lighter take. You can also substitute Parmesan with another sharp cheese like Asiago or Pecorino Romano. And while rotini is a favorite for its sauce-catching shape, feel free to use fettuccine, bowtie, or even gluten-free pasta.

Prefer a bit more heat? A pinch of cayenne or a few dashes of hot sauce will do the trick. Want it milder? Reduce the Cajun seasoning slightly and stir in a bit more cream.

Serving and Pairing Suggestions

This pasta pairs beautifully with a crisp side salad, especially one with a zesty vinaigrette to cut through the richness. Garlic bread is a must if you’re like me and want every drop of that creamy sauce soaked up. A side of roasted vegetables like asparagus or broccoli complements the spice with earthy notes.

For drinks, a chilled glass of white wine—like Sauvignon Blanc or Chardonnay—balances the creaminess and heat. Lemon-infused sparkling water is a refreshing non-alcoholic option.

Storage and Reheating Tips

Store any leftovers in an airtight container in the refrigerator for up to 3 days. When reheating, add a splash of cream or milk to loosen the sauce, and warm it gently over the stove or in the microwave. Stir often to maintain that silky texture and prevent the shrimp from overcooking.

This dish doesn’t freeze well because the cream sauce can separate, so I recommend enjoying it fresh or within a few days.
