Ingredients at a Glance

• 8 oz fettuccine pasta
• 1 lb shrimp, peeled and deveined
• 2 tbsp olive oil
• 3 cloves garlic, minced
• 1 cup heavy cream
• 1/2 cup grated Parmesan cheese
• 1 tbsp Cajun seasoning
• Salt and pepper to taste
• 2 green onions, sliced
• Fresh parsley, chopped for garnish

Tools & Equipment Needed

• Large pot – for boiling pasta
• Large skillet or sauté pan – to cook shrimp and sauce
• Colander – to drain pasta
• Garlic press or knife – for mincing garlic
• Wooden spoon or silicone spatula – for stirring
• Measuring cups and spoons – for precise ingredients

Stepwise Method: Creamy Cajun Shrimp Alfredo Pasta

Step 1: Cook the Fettuccine

Bring a large pot of salted water to a boil. Add the fettuccine pasta and cook according to the package instructions until al dente, typically about 10-12 minutes. Drain the pasta and set aside, reserving about 1/2 cup of the pasta water for later.

Step 2: Season and Sauté the Shrimp

While the pasta cooks, heat the olive oil in a large skillet over medium-high heat. Toss the shrimp with Cajun seasoning, salt, and pepper. Add the shrimp to the skillet and cook for 2-3 minutes on each side until pink and opaque. Remove the shrimp from the pan and set aside.

Step 3: Build the Alfredo Sauce

In the same skillet, reduce the heat to medium and add the minced garlic. Sauté for about 30 seconds until fragrant but not browned. Pour in the heavy cream and bring to a gentle simmer, stirring frequently.

Step 4: Add Cheese and Adjust Consistency

Gradually whisk in the grated Parmesan cheese until the sauce becomes smooth and creamy. If the sauce is too thick, add reserved pasta water a tablespoon at a time until you reach your desired consistency.

Step 5: Combine Pasta and Shrimp

Add the cooked fettuccine and sautéed shrimp back into the skillet with the Alfredo sauce. Toss everything gently to coat the pasta and shrimp evenly with the sauce.

Step 6: Garnish and Serve

Sprinkle sliced green onions and fresh parsley over the top before serving. Serve immediately for the best texture and flavor.

Easy Ingredient Swaps

• Pasta: Swap fettuccine with linguine, penne, or even gluten-free pasta to suit dietary needs.
• Shrimp: Use chicken breast strips for a land-based protein alternative or firm tofu for a vegetarian twist.
• Heavy Cream: Substitute with full-fat coconut milk for a dairy-free option that still delivers creaminess.
• Parmesan Cheese: Try a vegan Parmesan alternative or nutritional yeast to keep the cheesy flavor without dairy.
• Cajun Seasoning: If you want less heat, reduce the quantity or use a mild paprika-based seasoning.

Easy-to-Miss Gotchas

• Don’t overcook the shrimp—it only takes a few minutes; overcooking can make them rubbery.
• Be careful not to burn the garlic when sautéing; burnt garlic turns bitter and can spoil the sauce.
• Reserve pasta water before draining. This starchy water helps loosen the sauce if it gets too thick.
• Allow the Parmesan cheese to melt slowly into the cream. Adding it too fast or over high heat may cause clumping.

Freezer-Friendly Notes

This Creamy Cajun Shrimp Alfredo Pasta is best enjoyed fresh, as freezing creamy sauces can sometimes affect texture. However, if you want to prep ahead, freeze the cooked shrimp and sauce separately in airtight containers. Thaw in the refrigerator overnight before reheating gently on the stovetop, stirring frequently to avoid separation. Cooked pasta can also be frozen but may become a bit softer upon reheating, so undercook slightly if you plan to freeze it.
