Ingredients:
- 4 (6 oz/170g) sirloin steaks, about 1-inch thick
- 1 lb (450g) large shrimp, peeled and deveined
- 2 tablespoons (30ml) olive oil
- 2 tablespoons (30g) blackening seasoning
- 1 tablespoon (15g) unsalted butter
- 8 tablespoons (113g) unsalted butter
- 4 cloves garlic, minced
- 1 ½ cups (355ml) heavy cream
- 1 cup (100g) freshly grated Parmesan cheese
- ½ teaspoon (3g) freshly ground black pepper
- ¼ teaspoon (1.5g) salt, or to taste
- Pinch of nutmeg (optional)
- 1 lb (450g) fettuccine pasta
- Water for boiling pasta
- Salt for pasta water
- Chopped fresh parsley (optional)
- Red pepper flakes (optional)
- Lemon wedges (optional)
Instructions:
- Pat the steak and shrimp dry with paper towels. Generously season both with blackening seasoning.
- Cook the fettuccine according to package directions until al dente. Reserve about 1 cup (240ml) of pasta water before draining.
- Heat olive oil in a large skillet or cast iron pan over medium-high heat until shimmering. Sear the steaks for 3-4 minutes per side for medium-rare, or until desired doneness is reached. Remove from pan and let rest for at least 5 minutes before slicing against the grain.
- Add butter to the same skillet. Cook the shrimp until pink and opaque, about 2-3 minutes per side. Remove from the pan and set aside.
- Melt butter in a small saucepan over medium heat. Add garlic and sauté for about 1 minute, until fragrant. Pour in heavy cream and bring to a simmer, stirring occasionally. Reduce heat to low and simmer for 5 minutes, or until slightly thickened.
- Remove from heat and stir in Parmesan cheese, black pepper, salt, and nutmeg (if using). Stir until the cheese is melted and the sauce is smooth. Add a splash of reserved pasta water if the sauce is too thick.
- Add the cooked pasta to the Alfredo sauce and toss to coat. Top with sliced steak and shrimp. Garnish with chopped parsley, red pepper flakes, and a squeeze of lemon juice (optional). Serve immediately.
