January 28, 2026 – by Charlene Jump to RecipePin Recipe

If you’re craving something zesty, this Cajun Shrimp Alfredo is a great option. It’s creamy, a little spicy, and comes together quickly. Plus, it’s perfect for busy nights when you want a simple meal that feels special.

This recipe prevents overcooked shrimp, controls Cajun seasoning intensity, and offers solutions for adjusting sauce thickness with reserved pasta water.

Creamy Cajun Shrimp Fettuccine - 1

I know how hard it can be to cook shrimp just right. They can go from juicy to rubbery so fast! This recipe helps time the cooking process perfectly, so you don’t have to worry about overcooking and ruining your meal.

It all comes together in about 30 minutes, which is a win in my book! Using fettuccine gives that nice, thick texture that really holds the Alfredo sauce. And don’t forget to save some pasta water; it’s a great trick to adjust the sauce to just the right texture.

Ingredient Notes

Creamy Cajun Shrimp Fettuccine - 2
  • Shrimp: You’ll want medium shrimp, peeled and deveined for easy cooking. Fresh or frozen works, but if you’re using frozen, thaw them first for best results.
  • Fettuccine noodles: Any brand of fettuccine works here! These noodles soak up that creamy sauce beautifully. Feel free to swap with linguine or spaghetti if you’d like a change.
  • Milk: The creaminess of your sauce relies on the type of milk you choose. I’d recommend whole milk for richness, but 2% can work if you want something lighter.
  • Freshly grated parmesan cheese: Grate your cheese right before using it for the smoothest, meltiest texture. Pre-grated cheese just doesn’t melt the same!
  • Cajun seasoning: This adds that spicy kick! You can buy a blend or make your own with spices like paprika, garlic powder, and cayenne if you’re feeling adventurous.

Recipe Tips

  • If shrimp starts to turn rubbery, aim to cook them until just opaque, which usually takes about 4 to 7 minutes.
  • When your sauce seems too thick, gradually incorporate reserved pasta water to achieve the desired creaminess.
  • For the smoothest sauce, always opt for freshly grated parmesan instead of pre-packaged alternatives.
  • If you want to keep your shrimp warm after cooking, covering them helps maintain heat and tenderness.
  • For the best seasoning flavor, stick to the recommended amount of Cajun seasoning to avoid overwhelming the dish.

Serving Suggestions

  1. Serve cajun shrimp fettuccine with a side salad to create a complete meal. Garlic bread also works well to absorb the sauce.
  2. You can use this cajun shrimp fettuccine in different recipes or as a base for seafood dishes. Consider pairing it with grilled vegetables or a light white wine for variety.
  3. Add a creamy or spicy sauce to complement the dish’s flavor. A touch of lemon juice can enhance the freshness of this meal.

Storage Guidelines

  • To keep your cajun shrimp fettuccine fresh, follow these storage tips:
  • Refrigeration: Store fettuccine in an airtight container in the fridge for up to 3 days to maintain freshness.
  • Freezing: Do not freeze. This dish does not maintain quality when frozen. It is best enjoyed fresh.

Recipe Variations

  • You can use 1 pound of sliced chicken breast instead of shrimp for a hearty protein option.
  • Add 1 tablespoon of garlic powder or 1 teaspoon of smoked paprika for an extra layer of flavor in your dish.
  • Either add 2 cups of fresh spinach or 2 cups of steamed broccoli to boost vegetable content.
  • If you’re serving more people, increase the quantities to 2 pounds of shrimp, 16 ounces of fettuccine, and 4 cups of milk.

Equipment

  • Large skillet
  • Tongs or slotted spoon
  • Measuring cups
  • Microplane or box grater

Ingredients

  • 1 pound medium shrimp peeled and tails removed, patted dry with a paper towel
  • 1 tablespoon Cajun seasoning
  • 4 tablespoons butter divided
  • 1 teaspoon olive oil
  • 1 tablespoon minced garlic
  • 3 tablespoons flour
  • 2 cups milk
  • 8 ounces fettuccine noodles
  • 2 cups reserved pasta water
  • 1 cup freshly grated parmesan cheese
  • 1 teaspoon salt or to taste
  • fresh chopped parsley

Instructions

  • Start by tossing the shrimp with Cajun seasoning until they are coated. You will notice the vibrant spices clinging to the shrimp, giving them a nice kick. This step makes all the difference, so do not skip it. Watch out for over-seasoning; the shrimp should be well-flavored but not overwhelming.
  • Add olive oil and 2 tablespoons of butter to a skillet and let it melt over medium heat. Once it is bubbling, throw in the seasoned shrimp. They should be bright pink and opaque in about 4 to 7 minutes. Keep an eye on them to prevent rubbery shrimp. After cooking, transfer them to a plate and cover them to keep warm.
  • Melt the remaining butter in the same skillet and sauté minced garlic until it is fragrant and golden. Add flour to create a roux, stirring for a minute before slowly whisking in the milk until it thickens slightly. Avoid lumps by being gentle while whisking.
  • In a large pot, boil some salted water, then add the fettuccine noodles. Cook until they are al dente, about 8-10 minutes. As they cook, the aroma of the pasta fills your kitchen. Just do not forget to reserve some pasta water before draining—it is liquid gold for the sauce!
  • Return the skillet with sauce to low heat and stir in the reserved pasta water to adjust the texture. Add the drained fettuccine, tossing until they are well coated. Be careful not to add too much water; you want a nice sauce consistency.
  • Sprinkle in the freshly grated parmesan cheese while stirring. The cheese will melt and create a velvety finish. If it does not melt smoothly, use freshly grated cheese for the best texture. Finally, gently fold in the shrimp, letting every bite be packed with flavor, and garnish with fresh chopped parsley for a pop of color.

Notes

Refrigerate in an airtight container at 40 degrees F for up to 3 days. Do not freeze. Use freshly grated parmesan for the smoothest sauce. Reserve pasta water to achieve desired sauce consistency. Do not forget to cover cooked shrimp to keep warm. Reheat on the stovetop over low heat, stirring gently until warmed through, about 5-7 minutes.
