Notes

Ingredients for Cajun Shrimp Alfredo Pasta
For the Shrimp:
  • 1 pound medium shrimp (peeled, deveined, tails removed) – Perfect for absorbing the Cajun seasoning.
  • 1 tablespoon Cajun seasoning – Store-bought or homemade for that signature heat.
  • 1 teaspoon olive oil – For cooking shrimp and adding richness.
  • 1 tablespoon minced garlic – Adds aroma and depth to the shrimp.
  • 4 tablespoons butter (divided) – For sautéing shrimp and creating the creamy sauce base.
For the Alfredo Sauce:
  • 3 tablespoons all-purpose flour – Thickens the sauce for a smooth, creamy texture.
  • 2 cups milk (or half-and-half for extra richness) – Forms the creamy base of the Alfredo sauce.
  • 2 cups reserved pasta water – Helps coat pasta and thicken the sauce naturally.
  • 1 cup freshly grated Parmesan cheese – Adds saltiness and creamy flavor.
  • 1 teaspoon salt – Adjust to taste.
For the Pasta and Garnish:
  • 8 ounces fettuccine noodles – Classic choice that holds the creamy sauce perfectly.
  • Fresh chopped parsley – Adds a pop of color and freshness on top.
Pro Tip: Using freshly grated Parmesan ensures smooth melting and a richer taste. Avoid pre-shredded cheese for best results.
Step-by-Step Instructions
Step 1: Cook the Fettuccine
Bring a large pot of salted water to a boil. Cook the fettuccine according to package instructions until al dente. Drain, reserving 2 cups of pasta water. Toss noodles lightly with olive oil to prevent sticking and set aside.
Step 2: Cook the Shrimp
  • In a large skillet over medium heat, melt 1 tablespoon butter with 1 teaspoon olive oil. Add the shrimp and sprinkle with Cajun seasoning. Cook 4-7 minutes, turning occasionally, until shrimp are opaque and cooked through. Remove from skillet and cover to keep warm.
Step 3: Make the Alfredo Sauce
  • Without cleaning the skillet, melt the remaining 3 tablespoons of butter over medium heat. Add minced garlic and sauté 1 minute until fragrant. Stir in flour and cook another minute to eliminate raw taste. Gradually whisk in milk and reserved pasta water, stirring continuously until smooth. Add Parmesan and salt, stirring until the sauce thickens to your desired consistency. Taste and adjust seasoning.

Step 4: Combine Shrimp and Pasta

Return cooked fettuccine and shrimp to the skillet. Toss everything together, ensuring pasta is fully coated in creamy Alfredo sauce. Heat gently for 1-2 minutes to let flavors meld together.
Step 5: Serve
Plate the Cajun Shrimp Alfredo Pasta, sprinkle with fresh chopped parsley, and top with extra Parmesan if desired. Serve immediately while hot and creamy.
Tips for the Perfect Cajun Shrimp Alfredo
  • Avoid overcooking shrimp: Shrimp cook quickly and can become rubbery if overdone. Remove from heat as soon as they turn pink and opaque.
  • Fresh Parmesan is key: Pre-shredded cheese may contain anti-caking agents that affect smooth melting.
  • Adjust sauce thickness: Add more pasta water if the sauce is too thick, or simmer slightly longer if too thin.
  • Spice level: Increase or decrease Cajun seasoning based on your preference.
  • Optional vegetables: Sauté mushrooms, spinach, or bell peppers with garlic for extra flavor and nutrition.
Variations to Try
  • Creamier Sauce: Replace milk with heavy cream or a half-and-half mixture for a richer texture.
  • Different Pasta: Swap fettuccine with penne, linguine, or spaghetti. Sauce will coat any shape beautifully.
  • Protein Swap: Try chicken, scallops, or even tofu for a different protein option.
  • Spicy Kick: Add red pepper flakes or hot sauce to enhance the Cajun heat.
