Cajun Shrimp Sausage Alfredo

Ingredients:

  • For the Alfredo Sauce:
    • 1 pound (4 sticks) unsalted butter
    • 8 cloves garlic, minced
    • 4 cups heavy cream
    • 1 teaspoon salt, or to taste
    • 1/2 teaspoon black pepper, or to taste
    • 1/4 teaspoon nutmeg, freshly grated
    • 2 cups grated Parmesan cheese, plus more for serving
    • 1/2 cup grated Pecorino Romano cheese, plus more for serving
  • For the Cajun Shrimp and Sausage:
    • 1 pound large shrimp, peeled and deveined
    • 1 pound Andouille sausage, sliced into 1/4-inch thick rounds
    • 2 tablespoons olive oil
    • 1 red bell pepper, thinly sliced
    • 1 green bell pepper, thinly sliced
    • 1 yellow onion, thinly sliced
    • 2 stalks celery, thinly sliced
    • 2 tablespoons Cajun seasoning (store-bought or homemade)
    • 1 teaspoon smoked paprika
    • 1/2 teaspoon cayenne pepper (optional, for extra heat)
    • 1/4 cup chopped fresh parsley, for garnish
    • 1/4 cup chopped green onions, for garnish
  • For the Pasta:
    • 1 pound fettuccine pasta
    • Salt, for pasta water

Preparing the Cajun Shrimp and Sausage:

  1. Prepare the Shrimp: Pat the shrimp dry with paper towels. This helps them get a nice sear. In a medium bowl, toss the shrimp with 1 tablespoon of the Cajun seasoning, smoked paprika, and cayenne pepper (if using). Make sure the shrimp are evenly coated.
  2. Sauté the Sausage: In a large skillet or Dutch oven, heat 1 tablespoon of olive oil over medium-high heat. Add the sliced Andouille sausage and cook until browned and slightly crispy, about 5-7 minutes. Remove the sausage from the skillet and set aside. Don’t wipe out the skillet; we want to keep all those delicious sausage drippings!
  3. Sauté the Vegetables: Add the remaining 1 tablespoon of olive oil to the skillet. Add the sliced bell peppers, onion, and celery. Cook, stirring occasionally, until the vegetables are softened and slightly caramelized, about 8-10 minutes. This step is crucial for building flavor, so don’t rush it!
  4. Cook the Shrimp: Add the seasoned shrimp to the skillet with the vegetables. Cook for 2-3 minutes per side, or until the shrimp are pink and opaque. Be careful not to overcook the shrimp, as they can become rubbery.
  5. Combine Shrimp and Sausage: Return the cooked sausage to the skillet with the shrimp and vegetables. Toss everything together to combine. Reduce the heat to low and keep warm while you prepare the Alfredo sauce and pasta.

Making the Alfredo Sauce:

  1. Melt the Butter: In a large, heavy-bottomed saucepan or Dutch oven, melt the butter over medium heat. Make sure the butter doesn’t brown or burn.
  2. Sauté the Garlic: Add the minced garlic to the melted butter and cook for about 1 minute, or until fragrant. Be careful not to burn the garlic, as it will become bitter.
  3. Add the Cream: Pour in the heavy cream and bring to a gentle simmer. Reduce the heat to low and let the cream simmer for about 10-15 minutes, or until it has slightly thickened. Stir occasionally to prevent scorching.
  4. Add Seasonings: Stir in the salt, pepper, and freshly grated nutmeg. Taste and adjust seasonings as needed. Remember that the Parmesan and Pecorino Romano cheeses are also salty, so don’t over-salt the sauce.
  5. Incorporate the Cheese: Remove the saucepan from the heat. Gradually whisk in the grated Parmesan and Pecorino Romano cheeses, a little at a time, until the sauce is smooth and creamy. Make sure the cheese is fully melted and incorporated before adding more. If the sauce becomes too thick, you can add a splash of pasta water to thin it out.
  6. Keep Warm: Keep the Alfredo sauce warm over very low heat while you cook the pasta. Stir occasionally to prevent a skin from forming on the surface.

Cooking the Pasta and Assembling the Dish:

  1. Cook the Pasta: Bring a large pot of salted water to a rolling boil. Add the fettuccine pasta and cook according to package directions, or until al dente. Reserve about 1 cup of pasta water before draining the pasta.
  2. Combine Pasta and Alfredo Sauce: Drain the pasta and immediately add it to the saucepan with the Alfredo sauce. Toss the pasta and sauce together until the pasta is evenly coated. If the sauce is too thick, add a little of the reserved pasta water to thin it out to your desired consistency.
  3. Add Shrimp and Sausage: Add the Cajun shrimp and sausage mixture to the pasta and Alfredo sauce. Gently toss everything together to combine. Be careful not to break the shrimp.
  4. Serve: Serve the Cajun Shrimp Sausage Alfredo immediately. Garnish with chopped fresh parsley and green onions. Offer extra grated Parmesan and Pecorino Romano cheese on the side.

Tips for the Best Cajun Shrimp Sausage Alfredo:

  • Use High-Quality Ingredients: The quality of your ingredients will directly impact the flavor of the dish. Use good quality butter, heavy cream, Parmesan cheese, and Pecorino Romano cheese.
  • Don’t Overcook the Shrimp: Overcooked shrimp are rubbery and unpleasant. Cook the shrimp just until they are pink and opaque.
  • Grate Your Own Cheese: Pre-shredded cheese often contains cellulose, which can prevent it from melting smoothly. Grate your own Parmesan and Pecorino Romano cheese for the best results.
  • Adjust the Heat: If you prefer a milder dish, reduce the amount of Cajun seasoning and cayenne pepper. If you like it spicier, add more!
  • Make it Ahead: The Alfredo sauce can be made ahead of time and stored in the refrigerator for up to 3 days. Reheat gently over low heat before adding the pasta. The shrimp and sausage mixture can also be made ahead of time and stored in the refrigerator for up to 2 days.
  • Pasta Water is Key: Don’t forget to reserve some pasta water before draining the pasta. The starchy water helps to thicken the sauce and bind it to the pasta.
Variations:
  • Add Vegetables: Feel free to add other vegetables to the dish, such as mushrooms, spinach, or sun-dried tomatoes.
  • Use Different Pasta: You can use any type of pasta you like, such as penne, linguine, or spaghetti.
  • Add Chicken: If you’re not a fan of sausage, you can substitute cooked chicken.
  • Make it Vegetarian: Omit the shrimp and sausage and add extra vegetables for a vegetarian version.
  • Spice it Up: Add a pinch of red pepper flakes for extra heat.
