01 - Bring a large pot of salted water to a boil. Cook fettuccine according to package directions until al dente. Reserve 1/2 cup of pasta cooking water before draining.
02 - Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Season shrimp with salt and pepper, then cook for 2–3 minutes per side until pink and opaque. Transfer to a plate.
03 - Reduce heat to medium. Add butter and remaining olive oil to the skillet. Sauté minced garlic for 30 seconds until fragrant.
04 - Pour in heavy cream and bring to a gentle simmer. Whisk in Parmesan cheese, black pepper, salt, and nutmeg. Simmer for 2–3 minutes, stirring constantly, until slightly thickened.
05 - Add drained fettuccine to the saucepan and toss to coat. Add reserved pasta water as needed to achieve desired consistency.
06 - Return shrimp to the pan and toss gently. Stir in fresh parsley. Serve immediately, garnished with additional parsley and lemon wedges.
