Why These Ingredients Matter

Instructions for Making Creamy Cajun Shrimp Pasta
Step-by-Step Directions
Step 1: Bring a large pot of lightly salted water to a boil. Cook the pasta according to package directions until al dente. Reserve 1/2 cup pasta water before draining.
Step 2: While the pasta cooks, mix all ingredients for your homemade Cajun seasoning recipe in a small bowl. Pat shrimp dry and toss with half the seasoning mixture, coating evenly.
Step 3: Heat olive oil in a large skillet over medium-high heat. Add seasoned shrimp and cook 2-3 minutes per side until pink and slightly blackened. Remove shrimp and set aside.
Step 4: In the same skillet, melt butter and add minced garlic. Cook for 30 seconds until fragrant, then whisk in tomato paste and remaining Cajun seasoning.
Step 5: Pour in chicken broth and heavy cream, whisking constantly. Bring to a gentle simmer and cook for 3-4 minutes until slightly thickened into a gorgeous Cajun cream sauce.
Step 6: Add cooked pasta to the skillet along with Parmesan cheese, tossing to coat. Add reserved pasta water if needed for consistency. Return shrimp to the pan and toss gently.
Step 7: Garnish with chopped green onions and fresh parsley. Serve immediately while hot and creamy.
Hint: Don’t overcook the shrimp! They’ll continue cooking slightly when you add them back to the hot sauce, so aim for just pink and starting to curl. Overcooked shrimp become rubbery and tough.
Top Tip
The secret to perfect creamy Cajun shrimp pasta is getting that beautiful caramelization on your shrimp without overcooking them. Make sure your pan is hot before adding the shrimp, and don’t crowd them – cook in batches if needed. For the creamiest sauce, keep your heat at medium-low once you add the cream to prevent it from breaking or curdling.
If your sauce seems too thick, that reserved pasta water is liquid gold for getting the perfect consistency that coats every strand of this best Cajun pasta beautifully. This technique works for all kinds of shrimp dishes and pasta dinners, similar to my longhorn parmesan crusted chicken recipe approach to perfect sauce consistency.
My Cajun Cooking Adventure
Growing up, I thought Cajun food was just “spicy food with an accent” until Grandma decided to teach me about real Louisiana flavors. She pulled out this old, stained recipe card from her collection and announced we were making “proper Cajun shrimp” for Sunday dinner, explaining how creole seasoning differs from regular spice blends.
I’ll never forget watching her create her own homemade seasoning blend, measuring spices with her fingers instead of measuring spoons while humming old gospel songs. When I asked how much cayenne to add, she just winked and said, “Enough to make you remember it, but not enough to make you regret it.” I was so nervous about the spice level that I barely added any cayenne at all.
But Grandma was right about finding that perfect balance of heat and flavor. Now this creamy Cajun shrimp pasta recipe has become one of our most requested dinner recipes Cajun style, and I always think of her wisdom about spice balance every time I make these shrimp recipes for dinner.
Substitutions for Creamy Cajun Shrimp Pasta
If you need to adapt this pasta simple easy recipe for different tastes or dietary needs, here are substitutions that work beautifully.
Heavy cream – substitute with half-and-half for a lighter version, or use coconut cream for dairy-free creamy Cajun shrimp pasta. For Cajun shrimp pasta no cream, try using Greek yogurt mixed with a little pasta water for tang and creaminess.
Shrimp – chicken breast cut into bite-sized pieces works wonderfully for creamy Cajun shrimp and chicken pasta. You can also use scallops or even andouille sausage for a creamy Cajun shrimp pasta with sausage variation that adds smoky depth.
Fettuccine – any long pasta works great, or try penne for easier eating. For a lighter option, zucchini noodles or shirataki noodles create a low-carb version.
Cajun seasoning – if you don’t have all the spices, Old Bay seasoning or your favorite Cajun blend works in a pinch, just like when I make my honey garlic chicken breast recipe and need to adapt seasonings based on what’s available.

Equipment for Creamy Cajun Shrimp Pasta
A large, heavy-bottomed skillet is essential for this recipe because it distributes heat evenly and prevents the cream sauce from scorching. I love using my 12-inch stainless steel skillet because it gives the shrimp beautiful color and has enough room to toss the pasta without making a mess.
A large pasta pot with a good strainer insert makes the pasta cooking process much smoother, especially since timing is important for this one-pan dinner. Don’t forget to reserve that pasta water before draining – it’s the secret to a silky smooth sauce that clings perfectly to every strand.
If you’re scaling this up for a crowd, a large enameled cast iron Dutch oven works perfectly and goes from stovetop to table beautifully, just like when I make my garlic parmesan chicken and potatoes for family gatherings.
Storage Tips for Creamy Cajun Shrimp Pasta
Refrigerator storage:
- Store leftovers in airtight containers for up to 2-3 days

Grandma’s Secret for Creamy Cajun Shrimp Pasta
Grandma swears by blooming the spices in the hot butter before adding any liquid. “It wakes up all those sleeping flavors, Jazzy,” she always says with that knowing smile. She taught me to let the garlic and Cajun seasonings sizzle for just 30 seconds until they smell absolutely incredible, then quickly whisk in the tomato paste to create this amazing flavor base.
Her other secret? A tiny splash of hot sauce in the cream sauce – not enough to make it spicy, but just enough to enhance all those beautiful Cajun flavors and give the sauce a gorgeous subtle warmth that keeps people guessing what makes it so special.

Instructions
- First things first, let's get the pasta water going. Bring a large pot of water to a rolling boil and salt it generously. Grandma always said it should taste like the sea! Cook the [fettuccine pasta] until it's just al dente. Before you drain it, be a dear and save about a cup of that starchy pasta water, it’s liquid gold for the sauce later.
- While the pasta is bubbling away, grab a small bowl and mix together all the beautiful spices for the Cajun seasoning: the [paprika], [garlic powder], [onion powder], [oregano], [thyme], [cayenne pepper], [salt], and [black pepper]. Pat your [large shrimp] completely dry with a paper towel, then toss them with about half of this incredible spice blend until they’re all evenly coated.
- n your large skillet, heat the [olive oil] over medium-high heat. Once it shimmers, carefully place the seasoned shrimp in a single layer. Let them cook for 2-3 minutes per side. You’re looking for a beautiful pink color and a little bit of that gorgeous blackened crust. The most important rule from Grandma's kitchen: don't overcook them! Remove them from the pan and set them aside.
- In that same skillet, turn the heat down to medium and melt 3 tablespoons of [butter]. Add the minced [garlic] and let it cook for just 30 seconds until you can smell that wonderful aroma filling your kitchen. Now, whisk in the [tomato paste] and the rest of your homemade Cajun seasoning. Let it all sizzle for another 30 seconds. "You have to wake up the flavors, Lizzy," she'd tell me with a wink.
- Pour in the [chicken broth] to deglaze the pan, scraping up all those tasty browned bits from the bottom. Whisk in the [heavy cream] and bring the sauce to a gentle simmer. Let it bubble softly for 3-4 minutes, just until it starts to thicken into the most luscious, velvety sauce you've ever seen.
- Turn the heat to low. Add the drained pasta directly into the skillet with the sauce. Sprinkle in the freshly grated [Parmesan cheese] and the remaining 2 tablespoons of [butter], tossing everything gently until the pasta is coated and the cheese is melted and glorious. If it’s a bit too thick, add a splash of that reserved pasta water to get it just right. Finally, return the cooked shrimp to the pan and give it one last gentle toss.
- This is the moment we've been waiting for. Serve the pasta immediately in warm bowls, garnished with a generous sprinkle of fresh [green onions] and [parsley]. It’s best enjoyed right away, surrounded by people you love.
Notes
- Grandma’s Heat Control: If you’re sensitive to spice, you can reduce the cayenne pepper to 1/4 teaspoon. If you love the heat, feel free to add a little more!
- Substitutions: This recipe is just as wonderful with chicken breast (cut into bite-sized pieces) or andouille sausage for a smokier flavor.
- Storage: Leftovers will keep in an airtight container in the fridge for up to 2 days. The sauce will thicken when cold, so reheat it gently on the stove with a splash of milk or cream to bring it back to life.
