Start by cooking the fettuccine noodles according to the package instructions. Make sure to cook them al dente, as they will continue to cook when combined with the sauce later on. Once cooked, drain the noodles and set them aside.
In a large skillet, melt the butter over medium heat. Add the minced garlic and sauté for about a minute until fragrant. Be careful not to burn the garlic as it can turn bitter.
Next, add the shrimp to the skillet and season with salt and pepper. Cook the shrimp for about 2-3 minutes per side until they turn pink and opaque. Remove the shrimp from the skillet and set them aside.
In the same skillet, reduce the heat to low and pour in the heavy cream. Stir the cream gently and let it simmer for a couple of minutes until it starts to thicken slightly.
Gradually whisk in the grated Parmesan cheese, making sure it melts evenly into the cream sauce. Continue to stir until the sauce is smooth and creamy.
Add the cooked fettuccine noodles to the skillet and toss them in the sauce until they are well coated. Cook for another minute or two to allow the flavors to meld together.
Return the cooked shrimp to the skillet and drizzle the fresh lemon juice over the dish. Gently toss everything together to combine.
Remove the skillet from the heat and garnish the Shrimp Fettuccine with chopped fresh parsley for a pop of color and added freshness.
Serve the Shrimp Fettuccine immediately while it's still hot and enjoy the delightful combination of flavors and textures.
