Ingredients You’ll Need

The flavor magic lies in combining fresh ingredients with a homemade (or carefully chosen) Cajun seasoning blend, creamy parmesan, and perfectly cooked shrimp and pasta. I recommend using good-quality parmesan and fresh shrimp for the best results—trust me, it makes a world of difference.

• Kosher salt: Essential for seasoning your pasta water and bringing out the flavors in the shrimp; it’s a small touch that elevates the whole dish.
• Penne pasta: I love penne here because its ridges catch the creamy sauce beautifully, but feel free to swap with your favorite short pasta.
• Raw shrimp: Deveined and with tails removed for easy eating; pat them dry so they brown nicely instead of steaming.
• Cajun seasoning: Homemade is ideal to control salt and heat levels, but store-bought works in a pinch—just start light and adjust to taste.
• Olive oil: Helps the shrimp crisp up and adds a fruity depth to the dish.
• Butter: Adds richness and helps meld the sauce ingredients together.
• Heavy cream: Creates a luscious, velvety sauce that coats the pasta and balances the spice.
• Parmesan cheese: Freshly grated from a block for the best melt and flavor—you won’t want the pre-grated stuff here!

Variations

I love how forgiving this Cajun Shrimp Pasta Recipe is when it comes to tweaks—you can easily make it spicier, swap proteins, or add veggies to suit whatever you’re craving or have on hand.

• Less Spice: If you’re sensitive to heat, simply reduce the cayenne and red pepper flakes in the Cajun seasoning—I’ve done this for guests and still ended up with tons of flavor.
• Protein Swaps: I often make this with chicken breasts or wild scallops instead of shrimp, and it’s just as delicious—sometimes even better for those who want a meatier bite.
• Veggie Boost: Throw in some sautéed bell peppers, spinach, or cherry tomatoes to add freshness and color.
• Dairy-Free: Use coconut cream instead of heavy cream and a nutritional yeast blend for the cheesy flavor if you want to skip dairy.

How to Make Cajun Shrimp Pasta Recipe

Step 1: Season and Prep Your Shrimp

This is where the bold flavor starts. Toss your peeled, deveined shrimp with the Cajun seasoning and olive oil until they’re thoroughly coated. I like to pat the shrimp dry before seasoning—it helps them get that fantastic golden sear instead of steaming in the pan.

Step 2: Cook the Pasta and Reserve the Water

Bring a pot of salted water to a rolling boil and add your penne pasta. While it cooks al dente (usually about 8-10 minutes), scoop out at least ½ cup of that starchy cooking water—this little trick lets you thin the sauce later if it gets too thick. Once the pasta is just right, drain and set it aside.

Step 3: Sear the Shrimp

Heat a large skillet over medium-high heat and melt the butter. Add the seasoned shrimp in a single layer—you want space so they brown nicely. Cook until golden on one side (about 2 minutes), then flip once and cook another 2 minutes until done. I sometimes do this in batches to avoid overcrowding, which can cause the shrimp to steam instead of sear.

Step 4: Create the Creamy Sauce

Lower the heat to medium and pour in the heavy cream. Use a wooden spoon to scrape any flavorful browned bits off the pan’s bottom—those little bits add so much depth to your sauce. Let the cream bubble gently around the edges, then reduce to low and stir in the freshly grated parmesan until melted and smooth.

Step 5: Combine and Serve

Add the cooked pasta and shrimp back into the sauce, tossing to coat every piece. If the sauce feels too thick, add your reserved pasta water a tablespoon at a time until you get that perfect creamy yet light consistency. Give it a quick taste and adjust salt if needed, then serve immediately!

How to Serve Cajun Shrimp Pasta Recipe

Garnishes

I love topping this dish with a sprinkle of fresh chopped parsley or chives—the green adds a fresh pop of color and cuts through the creaminess. A squeeze of lemon juice right before serving brightens everything up beautifully. Sometimes I add a little extra parmesan on top for cheesy goodness.

Side Dishes

This Cajun Shrimp Pasta pairs wonderfully with a crisp Caesar salad or a simple mixed greens salad to lighten the meal. Garlic bread is a personal favorite for soaking up every last bit of that creamy sauce. Roasted vegetables like asparagus or broccoli also make a perfect, easy side.

Creative Ways to Present

For a dinner party, I sometimes serve the pasta in individual shallow bowls topped with whole shrimp for a dramatic effect. Adding a vibrant chili oil drizzle or crispy fried shallots can wow your guests and add a layer of texture. It’s always a fun twist that makes this comfort food feel a little more gourmet.

Make Ahead and Storage

Storing Leftovers

I usually store leftovers in an airtight container in the fridge for up to 2 days. The pasta soaks up the sauce over time, so it’s best reheated gently with a splash of cream or water to bring back that saucy texture.

Freezing

While I don’t often freeze this recipe due to the cream sauce, I’ve tried freezing just the cooked shrimp and pasta separately, which freezes well. You can then thaw and gently reheat with fresh cream and cheese to revive the sauce, but expect a slight texture difference.

Reheating

Reheat leftovers over low heat in a saucepan with a little bit of milk, cream, or reserved pasta water to loosen the sauce. Stir frequently to prevent sticking and keep the shrimp tender. Avoid microwaving if you can — it tends to make the shrimp rubbery.
