Ingredients Overview

This dish is built on a few high-quality ingredients. Each one plays a big role in achieving that signature Alfredo texture and deep shrimp flavor.

Shrimp

• Use raw, peeled, and deveined shrimp, medium or large (tail-off for easy eating).

• Fresh or thawed frozen shrimp work well.

• Pat dry before cooking for a better sear.

Flavor tip: Season with salt, black pepper, garlic powder, and a pinch of red pepper flakes for subtle heat.

Alternative: Substitute scallops, lobster chunks, or even grilled chicken for variation.

Fettuccine Pasta

• Classic Alfredo calls for fettuccine, with its flat, wide strands perfect for holding creamy sauce.

• Cook al dente, reserve ½ cup of pasta water before draining.

Substitutes: Linguine, tagliatelle, or gluten-free pasta varieties all work well.

Homemade Alfredo Sauce

A rich and creamy sauce made with:

• Butter: Unsalted, for control over seasoning.

• Garlic: Fresh minced garlic adds savory depth.

• Heavy cream: Essential for a silky, rich base.

• Parmesan cheese: Freshly grated for best melt and flavor.

• Salt and pepper: Simple seasoning keeps the flavors clean.

Optional: A pinch of nutmeg or lemon zest to brighten the sauce.

Fresh Parsley or Basil

• Chopped herbs finish the dish with a touch of freshness and color.

Optional additions:

• Lemon wedges for squeezing

• Extra Parmesan on top

• Crushed red pepper flakes for added spice

• Cajun Shrimp Alfredo: Use Cajun seasoning on shrimp and add smoked paprika to the sauce.

• Spinach or peas: Stir in fresh baby spinach or thawed peas just before serving.

Dietary Substitutions

• Gluten-free: Use GF fettuccine or rice noodles.
