Ingredient Notes

  • Butter: You’ll want to go with good ol’ salted butter; it brings richness and a lovely buttery flavor that really pulls everything together.
  • Heavy cream: This makes the sauce super creamy and smooth. Look for a fresh option, and don’t be afraid to pick a brand you know and love!
  • Parmesan cheese: Use finely grated real Parmesan for that authentic taste. It melts beautifully and gives a touch of salty goodness. Avoid the powdered stuff!
  • Sardo Marinated Seafood Salad or Shrimp: This is the star of the dish! If you want, you can swap this with fresh shrimp or other seafood, just make sure it’s cooked through properly.
  • Cooked fettuccini: This pasta’s flat shape holds onto the sauce so well! Feel free to switch to your favorite pasta if you’re not a fettuccini fan, but keep it similar in thickness.

Recipe Tips

  • If sauce is too thick, gradually incorporate reserved pasta water until you achieve the desired consistency.
  • When you notice bland flavors, try adjusting with a bit more salt, pepper, or a splash of lemon juice for brightness.
  • If pasta becomes overcooked, remember to aim for al dente next time and save some cooking water for the sauce.
  • For a restaurant-quality taste, always use real Parmesan cheese instead of the pre-grated kind.
  • When preparing seafood fettuccine without fresh ingredients, marinated seafood is a great time-saver for busy weeknights.

Serving Suggestions

  1. This seafood fettuccine alfredo pairs well with crusty bread to soak up the sauce. A light green salad dressed with vinaigrette complements this dish effectively.
  2. You can also serve it with white wine like crisp Sauvignon Blanc to enhance the meal. This dish fits into various dining occasions and can satisfy different tastes.
  3. Add a simple lemon butter sauce for an extra touch to the dish. A sprinkle of fresh herbs can also brighten the presentation and flavor.

Storage Guidelines

  • To keep your seafood fettuccine alfredo fresh, follow these storage tips:
  • Refrigeration: Store leftovers in an airtight container in the fridge for up to 2 days. Consume within this time for safety.
  • Freezing: Wrap the dish in plastic wrap or aluminum foil, then place it in a freezer bag. Freeze for up to 3 months. Thaw in the fridge before reheating.
  • Reheating: Warm in a skillet over low heat, adding a splash of liquid if needed to restore creaminess.

Recipe Variations

  • You can use grilled chicken instead of the marinated seafood for a delicious protein shift.
  • Add 1 teaspoon of garlic powder and ½ teaspoon of black pepper for an extra flavor kick.
  • Either substitute the heavy cream with 1 ½ cups of half-and-half or choose 1 ½ cups of coconut cream for a dairy-free option.
  • If making for a larger group, scale up to ½ cup of butter, 3 cups of heavy cream, and 3 cups of Parmesan.

Course: Dinner, Main Course

Equipment

  • Large saucepan
  • Measuring cups
  • Measuring spoons
  • Colander

Ingredients

  • ¼ c Butter (60ml)
  • 1 Garlic clove, minced
  • 1 ½ c Heavy cream (360ml)
  • 1 ½ c Parmesan (150g), finely grated
  • ½ teaspoon Fresh finely ground pepper
  • 2 tablespoon Dry white wine or lemon juice (30ml) or 2 teaspoons lemon juice
  • 2 containers Sardo Marinated Seafood Salad or Shrimp drained
  • 4 c Cooked fettuccini or other long pasta (360g), cooked, 1/2 c (120ml) water reserved
  • ½ c Parsley (15g), roughly chopped plus more for garnish
  • Salt to taste
  • Pepper to taste

Instructions

  • Start by melting the butter in a skillet over medium heat. Let it get bubbly, then add the minced garlic so you can smell that amazing aroma. Be careful not to let the garlic brown too much, as it can turn bitter.
  • Pour in the heavy cream and sprinkle in the Parmesan, stirring constantly until everything is well combined and creamy. You will know it is ready when the sauce thickens slightly and starts to coat the back of a spoon. Avoid letting it boil, though, or your sauce might separate.
  • Add your Sardo Marinated Seafood Salad or shrimp to the creamy mixture and let it warm through. The seafood should be heated but not overcooked, keeping it tender and delicate. Watch out—if you leave it too long, you might end up with rubbery seafood.
  • Toss in the cooked fettuccini and gradually add some reserved pasta water until you reach your desired sauce consistency. It should look glossy and cling to the pasta nicely. If you skip adding water, the sauce might turn too thick and clumpy.
  • Sprinkle in the finely ground pepper along with salt to taste, mixing well. Then, fold in the roughly chopped parsley for a fresh finish. Do not forget to save some parsley for garnish! Taste and adjust as needed.
