To make the garlic parmesan cream sauce, melt butter in the skillet over medium heat. Add garlic, and cook, stirring frequently, until fragrant, about 1-2 minutes. Whisk in flour until lightly browned, about 1 minute.
Gradually whisk in beef broth, basil and oregano. Cook, whisking constantly, until incorporated, about 1-2 minutes. Stir in heavy cream, Parmesan and cream cheese until slightly thickened, about 1-2 minutes. If the mixture is too thick, add more heavy cream as needed; season with salt and pepper, to taste.
Preheat oven to broil. Place an oven-proof skillet in the oven.
Using paper towels, pat both sides of the steak dry. Drizzle with olive oil; season with salt and pepper, to taste. Remove skillet from the oven and heat over medium-high heat.
Place the steak in the middle of the skillet and cook until a dark crust has formed, about 1 minutes. Using tongs, flip, and cook for an additional 60 seconds.
Place skillet into the oven and cook until desired doneness is reached, about 4-5 minutes for medium-rare, flipping once. Let rest for 3-5 minutes.
Serve immediately with garlic parmesan cream sauce, garnished with parsley, if desired.
