Start by patting the steak dry with paper towels. This helps it get that golden, crispy sear. Rub olive oil on both sides and season generously with salt and pepper. Make sure the steak is at room temperature, as this ensures even cooking.
Heat a cast-iron skillet on high until it’s nearly smoking. Add the steaks and cook for 3-4 minutes on each side for a medium-rare finish. For a thicker cut, finish it in the oven at 400°F for 5-7 minutes. Rest the steak for 5 minutes to keep the juices inside.
While the steak is resting, prepare the shrimp. Heat a sauté pan with butter over medium heat and add minced garlic. Once fragrant, toss in the shrimp. Season lightly with salt and pepper, then cook for 2-3 minutes per side until pink and slightly firm. Remove and set aside.
Using the same pan, pour in the white wine to deglaze, scraping up the flavorful bits. Reduce the wine for about a minute, then stir in lobster stock. Simmer until it’s slightly reduced. Whisk in the heavy cream and butter to create a silky sauce. Add a pinch of red pepper flakes if you like some spice.
Plate each steak on a serving dish. Top with the cooked shrimp and generously spoon the lobster sauce over the top. Garnish with fresh parsley for a vibrant finish.
