Ingredients You’ll Need

This Cajun Shrimp Alfredo Pasta comes together with simple, staple ingredients, each one pulling its weight to deliver a lively fusion of flavors and a beautiful, colorful plate. Don’t skip any part—they all play their role, from the Cajun-kissed shrimp to the fresh herbs and buttery garlic toast for scooping up extra sauce.

Shrimp (1 lb, peeled and deveined): The star of the show, providing sweet, succulent bites that pair perfectly with spicy seasoning.
Cajun seasoning (1 tbsp): This bold blend is responsible for that unmistakable Louisiana flavor—adjust for your heat-level comfort!
Olive oil (2 tbsp, divided): Adds richness and ensures a golden sear on your shrimp and veggies.
Butter (3 tbsp, divided): Brings luxurious flavor to both the alfredo and the shrimp sauté.
Garlic (2 cloves, minced): The savory backbone—nothing says creamy comfort like garlic-infused sauce.
Red pepper flakes (1/2 tsp, optional): For chili heat enthusiasts, a dash turns things up a notch.
Heavy cream (1 cup): This is what makes the alfredo ultra-indulgent, creamy, and silky.
Parmesan cheese (1/2 cup, grated): Nutty, salty, and utterly essential for the best pasta sauce.
Cream cheese (2 tbsp): Secret ingredient alert! This helps thicken the sauce, making it ridiculously smooth.
Salt and pepper: Essential for bringing together all the flavors—don’t forget to taste and adjust.
Fresh parsley (1/4 cup, chopped): A sprinkle of green magic for freshness and color.
Pasta (8 oz spaghetti or linguine): Go classic or swap for your favorite noodle—the sauce clings to every strand.
Cherry tomatoes (1 cup, halved): A burst of juicy sweetness for contrast and color.
Bell peppers (1/2 cup, sliced): Adds crunch and a dash of natural sweetness.
Fresh basil (chopped): This garnish brightens the whole plate with a whisper of peppery flavor.
White or sourdough bread (4 slices): The best vehicle for soaking up leftover sauce.
Butter for toast (2 tbsp, softened): Needed for that golden, crisp garlic toast finish.
Garlic powder (1/2 tsp): Adds subtle, toasty garlic flavor to the bread without burning.
Salt for pasta water: Makes sure your noodles are seasoned all the way through.

How to Make Cajun Shrimp Alfredo Pasta

Step 1: Cook the Pasta

Bring a big pot of salty water to a rolling boil—imagine the ocean in a pot. Add your spaghetti or linguine and cook it until it’s al dente, with just enough bite so it won’t get mushy when tossed with the creamy Alfredo. Once it’s perfect, drain and set aside, saving just a touch of pasta water in case your sauce needs a little loosening later.

Step 2: Sauté the Cajun Shrimp

Toss your peeled and deveined shrimp with the Cajun seasoning so each piece gets a generous coat. In a hot skillet, melt a blend of olive oil and butter, then toss in those fiery shrimp. Give them about 2 to 3 minutes per side—when they turn pink and curl up, they’re ready. Remove them from the pan to avoid overcooking and set aside.

Step 3: Craft the Alfredo Sauce

In the same skillet (no need to clean—the shrimp’s flavor stays!), turn the heat to medium and melt more butter. Sauté your minced garlic quickly, just until fragrant. Pour in the heavy cream and spoon in the cream cheese; stir and watch as it emulsifies into a smooth, dreamy sauce. Sprinkle in grated Parmesan and stir until the sauce thickens and all cheesy bits melt. Season with salt, pepper, and a pinch of red pepper flakes if you like extra heat.

Step 4: Bring It All Together

Add your sautéed Cajun shrimp back into the pan with the Alfredo sauce, along with a shower of chopped parsley. Let everything simmer for two minutes so the shrimp soak up all the creamy, spicy flavors. Now, either toss your cooked noodles directly into the pan to coat, or lay the pasta on plates and top generously with the Cajun shrimp Alfredo.

Step 5: Make the Tomato & Pepper Medley

Heat a small skillet with a hit of olive oil. Toss in your halved cherry tomatoes and thin strips of bell pepper, sautéing for 4 to 5 minutes until soft and bursting with natural sweetness. Season lightly with salt and finish off with bright, fresh basil—this side salad cuts through the richness like a refreshing breeze.

Step 6: Prepare the Garlic Toast

Generously butter your bread slices and sprinkle with garlic powder for an extra punch of flavor. Toast in a pan over medium heat until golden and crisp. Not only do these make the kitchen smell like heaven, but they’re also perfect for enjoying every last drop of that velvety sauce.

How to Serve Cajun Shrimp Alfredo Pasta

Garnishes

A sprinkle of fresh parsley or basil goes a long way to enhance the vibrant look and flavor of your Cajun Shrimp Alfredo Pasta. If you like a little extra kick, add another pinch of red pepper flakes or a dusting of Parmesan. The final result looks restaurant-worthy while feeling every bit like the comfort food it truly is.

Side Dishes

This creamy pasta pairs wonderfully with a crisp green salad tossed in lemon vinaigrette or steamed broccoli for a pop of color and freshness. And don’t underestimate the power of more garlic toast—those golden slices are a non-negotiable for soaking up any lingering Alfredo sauce!

Creative Ways to Present

For a fun twist, serve your Cajun Shrimp Alfredo Pasta in individual shallow bowls, nestling the shrimp right on top and scattering cherry tomatoes around them. Or, layer everything family-style on a big platter so everyone can help themselves. Add a wedge of lemon for an extra pop of freshness, or sprinkle microgreens for a chef-inspired finish.

Make Ahead and Storage

Storing Leftovers

Leftover Cajun Shrimp Alfredo Pasta keeps well in an airtight container in the fridge for up to 2 days. Make sure to store the pasta and sauce together—as they sit, the flavors mingle and get even better. Just know that seafood is always best enjoyed fresh, so try to finish within a couple of days for peak flavor.

Freezing

While cream-based sauces can sometimes separate after thawing, you can freeze this dish if needed. Place cooled pasta in a freezer-safe container, and when ready to enjoy, thaw overnight in the fridge. Stir gently while reheating to help the sauce emulsify again. The shrimp’s texture may change slightly, but the flavor will still shine through.

Reheating

To reheat, add a splash of milk or a spoonful of cream to loosen the sauce and gently warm the pasta on the stovetop over low heat, stirring until heated through. If using a microwave, cover loosely and use short intervals, stirring in between to avoid overcooking the shrimp and breaking the sauce.

FAQs

Can I use pre-cooked shrimp for Cajun Shrimp Alfredo Pasta?

Absolutely! Just toss pre-cooked shrimp with Cajun seasoning and a bit of olive oil, then add them to the sauce just before serving. This keeps them tender and flavorful without the risk of overcooking.

What’s the best pasta shape for this recipe?

Spaghetti and linguine are classic and work beautifully because the sauce clings to each strand. However, penne, fettuccine, or even rotini would also be delicious and help catch all that creamy Alfredo.

How spicy is Cajun Shrimp Alfredo Pasta?

It’s as spicy as you want it to be! Cajun seasoning usually packs some heat, but you can dial it up or down by adjusting the amount used and adding (or skipping) red pepper flakes. Taste as you go for your preferred spice level.

Can I make this dish lighter?

Definitely! Swap heavy cream for half-and-half, use less butter, and feel free to use light cream cheese. Just note, the sauce may be a touch thinner, but you’ll still get loads of flavor in every bite.

What protein can I substitute for shrimp?

If shrimp isn’t your thing, try chicken breast (sliced thin and seasoned the same way), or even sautéed scallops for a different seafood spin. Tofu also soaks up that Cajun flavor beautifully for a vegetarian version.
