20-30 minutes before you’re ready to start cooking, remove the steaks from the fridge. Sprinkle both sides evenly with Kosher salt and fresh cracked pepper. Rest at room temperature.
Bring a large pot of salted water to a boil.
Heat the neutral oil in a large cast iron skillet over high heat. When the oil is shimmering, add the steaks. Sear for 3-4 minutes or until a browned crust has formed. Flip, and sear another 2-3 minutes. Remove to a plate and tent with foil.
Add the pasta to the boiling water. Set a timer according to the al dente instructions on the box.
Eeturn the same cast iron skillet to the stove over medium heat. Melt butter and olive oil. Add garlic and sauté until fragrant, about 1 minute. Add wine or broth, salt, red pepper flakes, lemon zest, and plenty of black pepper and bring to a simmer. Cook for about 2 minutes, or until wine is reduced by half.
Add shrimp and sauté about 1 minute, flip, and cook another 1-2 minutes until pink. Remove from heat, then stir in the parsley and lemon juice.
Drain the pasta, then plate it with the steak and shrimp on top. Drizzle extra scampi sauce over the steak and pasta. Serve with fresh lemon wedges.
