Season the Steaks: Begin by seasoning both sides of the 2 ribeye or sirloin steaks (8 oz each) with salt and pepper. This simple step ensures that the flavor penetrates the meat, enhancing its taste once cooked.
Heat the Olive Oil: In a skillet, heat 2 tbsp of olive oil over medium-high heat. Once hot, carefully place the steaks in the skillet, searing them for 3-4 minutes on each side. The goal here is to achieve a beautiful golden-brown crust.
Let Rest: After both sides are browned, remove the steaks from the skillet and let them rest on a plate. This resting period allows the juices to redistribute within the meat, resulting in a juicier steak.
Sauté Garlic: Reduce the heat to medium. In the same skillet, add 2 tbsp of butter. Once melted, add the 4 minced garlic cloves and sauté until fragrant, being careful not to burn them.
Prepare the Cream Sauce: Stir in 1 cup of heavy cream, followed by 1/2 cup of grated Parmesan cheese, 1 tsp of Dijon mustard, and 1 tsp of fresh thyme leaves. Let the mixture simmer for 3-4 minutes, stirring frequently, until it thickens slightly.
Combine Steak and Sauce: Return the steaks to the skillet, allowing them to absorb the flavors. Spoon the creamy garlic sauce over the steaks and heat them for an additional 1-2 minutes.
Serve: Plate the steaks and spoon extra sauce over them. Garnish with fresh parsley if desired and serve hot. For a complete meal, consider pairing with sides like mashed potatoes or roasted vegetables.
