Cook the Shrimp
Heat olive oil or butter in a large skillet over medium heat.
Add minced garlic and sauté for 30 seconds until fragrant.
Add shrimp and season with salt, black pepper, and red pepper flakes.
Cook for about 2 minutes on each side until pink and opaque.
Remove shrimp from the skillet and set aside.
Cook the Pasta
Boil a large pot of water with 1 tbsp salt.
Cook fettuccine or linguine according to package instructions.
Reserve 2 tbsp pasta water before draining.
Drain the pasta and set aside.
Make the White Chocolate Alfredo Sauce
In the same skillet, melt butter over medium-low heat.
Pour in heavy cream and whole milk, stirring continuously.
Allow the mixture to heat up (but not boil) for about 2 minutes.
Add grated Parmesan cheese and stir until fully melted and smooth.
Reduce heat and add chopped white chocolate, stirring until completely melted.
Add salt, white pepper, and nutmeg (if using). Stir until well combined.
Combine the Dish
Add cooked pasta to the sauce and toss to coat evenly.
If the sauce is too thick, add reserved pasta water, one tablespoon at a time, to adjust consistency.
Mix in cooked shrimp and ensure even distribution.
Remove from heat and let flavors meld for a minute.
Garnish and Serve
Plate the pasta and sprinkle with chopped parsley.
Top with additional grated Parmesan cheese.
Add lemon zest for brightness (optional).
For extra texture, add crushed toasted almonds or macadamia nuts.
