First Step: PREPARE THE STEAK

1. Season the Steaks: Start by seasoning both sides of the steaks with salt, pepper, and garlic powder. Make sure the steaks are evenly coated to maximize flavor.
2. Heat the Skillet: Heat 2 tablespoons of olive oil in a large, heavy-bottomed skillet over medium-high heat. Let the oil heat up until it shimmers, but not to the point of smoking.
3. Sear the Steaks: Add the steaks to the hot skillet and sear them for about 4-5 minutes per side for medium-rare, or longer if you prefer them more done. Use tongs to flip the steaks and ensure they cook evenly. For a perfectly seared crust, resist the urge to move the steaks too much.
4. Finish the Steaks: When the steaks are almost done, add 1 tablespoon of butter to the pan. Spoon the melted butter over the steaks to add richness and enhance the flavor. Remove the steaks from the skillet and set them aside to rest for at least 5 minutes before serving.

Second Step: MAKE THE SHRIMP AND LOBSTER SAUCE

1. Cook the Shallots and Garlic: In the same skillet used for the steak, melt 1 tablespoon of butter over medium heat. Add the chopped shallot and cook for 2-3 minutes, or until soft and translucent. Add the minced garlic and cook for another 1 minute, stirring constantly to avoid burning.
2. Add the Liquids: Pour in the shrimp stock and white wine, scraping up any flavorful brown bits from the bottom of the skillet. This adds depth and richness to the sauce. Bring to a simmer and let it reduce by half, which should take about 4-5 minutes.
3. Add the Cream and Lobster Stock: Stir in the heavy cream and lobster stock, and continue to simmer for another 5 minutes until the sauce thickens slightly.
4. Add the Shrimp and Lobster: Add the shrimp to the sauce and cook for 2-3 minutes until they turn pink and opaque. Then, stir in the chopped lobster meat and cook for another minute, allowing it to warm through.
5. Finish the Sauce: Stir in the fresh lemon juice and chopped parsley. Taste the sauce and adjust the seasoning with salt and pepper as needed.

Final Step: ASSEMBLE AND SERVE

1. Plate the Steak: Place the rested steaks on serving plates.
2. Top with Shrimp and Lobster Sauce: Spoon the shrimp and lobster sauce over the steaks, ensuring each plate is generously topped with the seafood mixture.
3. Garnish: Optionally, garnish the dish with fresh thyme sprigs, additional parsley, or a sprinkle of grated Parmesan cheese for extra richness.
4. Serve Immediately: Serve the steak with shrimp and lobster sauce alongside your favorite sides, such as mashed potatoes, sautéed vegetables, or a fresh green salad.
