Ingredients

8 oz fettuccine pasta – the perfect base for our creamy sauce.
1 lb shrimp, peeled and deveined – fresh shrimp adds a lovely sweetness.
2 tablespoons olive oil – for sautéing the shrimp to golden perfection.
1 teaspoon Cajun seasoning – this is what gives our dish its signature kick!
3 cloves garlic, minced – because garlic makes everything better.
1 cup heavy cream – the star of our creamy sauce.
1 cup grated Parmesan cheese – adds a rich, cheesy flavor.
1/2 teaspoon salt – to enhance all the flavors.
1/4 teaspoon black pepper – just enough to add a hint of spice.
2 tablespoons chopped fresh parsley (for garnish) – for that pop of color and freshness.

How to Make Creamy Cajun Shrimp Alfredo 🍝🍤

Start by cooking the fettuccine pasta according to the package instructions. Once cooked, drain it and set it aside.
In a large skillet, heat the olive oil over medium heat. Add the shrimp to the skillet and sprinkle it with Cajun seasoning. Cook until the shrimp turns pink and opaque, which should take about 3-4 minutes. Once cooked, remove the shrimp from the skillet and set it aside.
In the same skillet, add the minced garlic and sauté for about 1 minute until it becomes fragrant. You want to be careful not to burn it!
Pour in the heavy cream and bring it to a gentle simmer. Stir in the Parmesan cheese, salt, and black pepper, mixing until the cheese is melted and the sauce becomes smooth.
Add the cooked fettuccine and shrimp back into the skillet, tossing everything together to coat the pasta and shrimp evenly with the creamy sauce.
Serve immediately, garnished with chopped parsley for a touch of freshness and color.

Substitutions & Additions

If you’re looking to switch things up a bit, here are some fun ideas:

Swap the fettuccine for penne or linguine if you prefer a different pasta shape.
Try adding some sautéed bell peppers or spinach for extra veggies.
If you want it spicier, consider adding a dash of hot sauce or red pepper flakes.
For a lighter version, you can use half-and-half instead of heavy cream.

Tips for Success

Here are a few handy tips to make sure your dish turns out perfectly:

Don’t overcook the shrimp; they cook quickly and can become rubbery if left too long.
Make sure to sauté the garlic just until fragrant to avoid a bitter taste.
You can prep the shrimp and sauce in advance and then combine everything just before serving.

How to Store Creamy Cajun Shrimp Alfredo 🍝🍤

If you have leftovers (which is rare because it’s so good), you can store them in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove or in the microwave, adding a splash of cream or water to loosen the sauce if it thickens up.
