While the steak is resting, turn down the heat to medium-low temperature and add butter to the small saucepan used to cook the steak
Once melted, add minced garlic and thyme sprigs and sauté everything together for 3-4 minutes until fragrant
To finish, pour in the cream and stir it continuously until thickened (approx 1-2 minutes).
Season with salt and pepper to taste, remove from heat once finished, and serve warm atop your filet mignon!
