Heat the oven to 275 degrees
Line a baking sheet with parchment
With paper towels, pat the steaks dry
Sprinkle them with salt and pepper
Usinga ramekin as a guide, cut the pastry sheets into circles 1” bigger than the top of the ramekin
Place the pastry circles on a tray, cover with a damp towel and place in the refrigeratorto chill until ready to fill ramekins
In a large (12-inch) cast-iron skillet or heavy skillet with an oven-proof handle over medium-high heat, heat 1 tablespoon of the oil
Add the steaks to the skillet and cook for 2 to 3 minutes on each side, turning with tongs, until a golden crust forms
Place the skillet in the oven and continue to cook for 4 to 6 minutes, or until a thermometer inserted into the center of the steaks registers 125 degrees
(the exact time will depend on the thickness of the steaks)
Remove the skillet from the oven and transfer the steaks to a plate to rest for 10 minutes
Cut into thin slices and set aside
Increase the oven temperature to 400 degrees
While the steak rests, set the skillet over medium-high heat and add the remaining 1 tablespoon oil
Add the mushrooms, pearl onions, shallot, and thyme sprigs to the skillet
Cook, stirring occasionally, for 5 to 6 minutes, or until the mushrooms start to brown
Stir in the paprika, Campbell’s® Cream of Mushroom Soup, sour cream and Worcestershire sauce to the skillet
Stir until the sauce bubbles (do not boil)
Return the steak to the skillet and mix to coat the meat well
Remove the skillet from the heat and remove the thyme sprigs
Stir in the chopped parsley
Divide the filling among 4 (8-ounce) ramekins
Set them on the parchment-lined baking sheet
Remove the pastry circles from the refrigerator
With the tip of a paring knife, cut a small cross in the center of each pastry circle
Brush a 1-inch border of egg wash around the circumference
Turn the pastry over so the unglazed sides are facing up and place them on top of the ramekins
Press the overhanging edges into the sides of the ramekins
Brush with more egg wash
Bake for 20 to 22 minutes, or until the pastry is golden brown
Let rest for 5 minutes
Transfer each pie to a plate with a wide spatula
Garnish each with a sprig of thyme
