01 - Remove steaks from the refrigerator 20 minutes before cooking. Pat dry with paper towels and season both sides generously with kosher salt and freshly ground black pepper.
02 - Heat olive oil in a large skillet over medium-high heat until shimmering. Add steaks and sear for 3 to 4 minutes per side for medium-rare doneness, adjusting time for preferred doneness.
03 - During the last 2 minutes of cooking, add 2 tablespoons butter, smashed garlic cloves, and thyme sprigs to the pan. Tilt the skillet and continuously spoon the melted garlic butter over the steaks for even basting.
04 - Transfer steaks to a clean plate and tent loosely with aluminum foil. Let rest for at least 5 minutes to allow juices to redistribute throughout the meat.
05 - Wipe out the skillet and return to medium heat. Add 2 tablespoons butter and minced garlic. Sauté for 1 minute until fragrant, being careful not to burn the garlic.
06 - Pour in broth and bring to a gentle simmer, using a wooden spoon to scrape up any browned bits from the bottom of the pan for added depth of flavor.
07 - Add heavy cream, cream cheese, salt, and pepper to the skillet. Whisk continuously until the cream cheese is completely melted and the mixture is smooth and well combined.
08 - Stir in freshly grated Parmesan cheese and simmer for 2 to 3 minutes, stirring frequently, until the sauce thickens enough to coat the back of a spoon.
09 - Return rested steaks to the pan and spoon the warm Parmesan cream sauce generously over each piece. Heat through for 1 to 2 minutes. Serve immediately topped with remaining sauce and garnish with chopped fresh parsley.
