This creamy Cajun shrimp pasta combines tender shrimp, vibrant vegetables, and a zesty Alfredo-style sauce. Swap in chicken, sausage, tofu, or omit the protein to make a vegetarian version.

He’s mostly vegetarian but eats seafood sometimes, always hungry for pasta, and insists on a big side salad saved for last. I eat mostly vegetarian too, but crave bold, savory, and spicy food, love colorful veggies on the plate, and prefer to cook with as few dishes as possible. The compromise? This dreamy, creamy Cajun pasta.
We cooked this together on a night when I wanted protein, so we added shrimp. (In Spain, peeling and deveining shrimp is a bit of work, but worth it.) We made a lighter Alfredo-style sauce, seasoned it with just enough Cajun spice for a lively kick without overwhelming milder palates, and tossed everything with sautéed peppers and onions, fresh spinach, and perfectly al dente pasta. Finished with extra Parmesan and sliced green onions, plus a big salad and a crisp white wine, it was a win for both of us — and even better when the dishes were taken care of afterward.
This dish is flexible: swap proteins, change the vegetables, or adjust the heat to suit your tastes. Below is a clear ingredient list and straightforward method so you can recreate this comforting, flavorful meal at home.
