Instructions

Step 1: Peel, rinse, and thoroughly dry the shrimp.

Step 2: Marinate the shrimp with lemon, oil, and spices, then toss in a light coating of cornstarch.

Step 3: Quickly pan-fry the shrimp 1–2 minutes per side until pink; then set aside.

Step 4: Sauté the vegetables in butter until softened and golden.

Step 5: Add tomato sauce and cream, return the shrimp, stir in parsley, and combine with al dente rigatoni.

Step 6: Finish and serve immediately, garnished with Parmesan, parsley, and black pepper.

Prepare the Shrimp:

Peel and rinse the shrimp, then pat dry. If using frozen shrimp, thaw in cold water for 5–10 minutes and separate as they thaw.
In a bowl, combine the shrimp with lemon juice, olive oil, Cajun seasoning, garlic powder, red paprika, smoked paprika, and dried oregano. Toss to coat, then dust lightly with cornstarch for a crisp sear.

Cook the Shrimp:

Heat a large skillet over medium-high heat with a small drizzle of oil.
Sear the shrimp 1–2 minutes per side until pink and opaque. Remove and keep warm.

Sauté the Vegetables:

In the same skillet, melt the butter over medium heat.
Add diced jalapeño, red bell pepper, and yellow onion. Sauté 7–10 minutes until soft and fragrant.

Prepare the Sauce:

Stir in the tomato sauce and cook briefly for 2–3 minutes to reduce raw acidity.
Pour in the heavy cream and add remaining Cajun seasoning, garlic powder, red and smoked paprika, and oregano. Stir until smooth and heated through.
Return the shrimp to the pan, add chopped parsley and grated Parmesan if using, and simmer 3–5 minutes to allow flavors to meld.

Cook the Pasta:

Cook rigatoni in a large pot of salted boiling water until al dente, following package directions. Reserve a cup of pasta water before draining.

Combine and Serve:

Add drained pasta to the skillet with the sauce, stirring in a splash of reserved pasta water to loosen and bind the sauce. Simmer a few minutes until the sauce clings to the pasta.
Adjust seasoning with salt and pepper to taste.

Garnish and Serve:

Serve hot, topped with extra grated Parmesan, chopped parsley, and a grind of black pepper. Enjoy this simple, flavorful pasta that’s now a fast favorite.

Substitutions for Creamy Cajun Shrimp Pasta

Shrimp: Use diced chicken breast, sliced andouille or smoked sausage, or firm tofu for a vegetarian option.

Lemon juice: Substitute lime juice or a splash of white wine vinegar.

Olive oil: Any neutral oil such as canola or sunflower works.

Cajun seasoning: Swap with Creole seasoning or a mix of chili powder, cumin, and cayenne.

Heavy cream: Use half-and-half, full-fat coconut milk for dairy-free, or milk thickened with a little flour.

Pasta: Penne, fusilli, or any short pasta work well; whole wheat is a healthier swap.

Feel free to adapt based on what you have available—this recipe is very forgiving and versatile.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove with a splash of water or broth to restore creaminess. For longer storage, freeze in a freezer-safe container for up to 2 months; thaw overnight in the fridge before reheating.

3 Top Tips for Success

Use quality ingredients: Fresh large shrimp, real butter, and full-fat cream make the richest sauce. Freshly grated Parmesan brightens the finish.
Cook pasta al dente: Slightly undercook the pasta so it finishes in the sauce without becoming mushy.
Reserve pasta water: A splash of starchy pasta water helps the sauce cling to the noodles and reach a silky consistency.

FAQ’s

What pairs well with Cajun pasta?

Pair this spicy, creamy pasta with a crisp green salad, garlic bread, or roasted vegetables to balance the richness. A cold glass of iced tea or a light white wine complements the dish nicely.

Is Cajun shrimp suitable for weight loss?

Shrimp itself is high in protein and relatively low in calories. To make a lighter version, use less oil and cream, increase vegetables, and serve a smaller portion of pasta.
