Step 1

To make the herb butter, in a small bowl, stir together the butter, rosemary, parsley and garlic, and season with salt and pepper. Form into a log, wrap in plastic wrap and refrigerate until ready to serve.

Step 2

Preheat an oven to 400°F (200°C).

Step 3

In a large ovenproof fry pan over medium heat, warm 1 Tbs. of the olive oil. Add the mushrooms and cook, stirring, until golden brown and tender, 6 to 8 minutes. Transfer to a plate.

Step 4

Season the steaks with salt and pepper. In the same skillet used for the mushrooms, over medium-high heat, melt 2 Tbs. of the butter with the remaining 1 Tbs. olive oil until shimmering. Add the steaks and sear for 2 minutes per side. Transfer to the oven and roast until the steaks are done to your liking, about 5 minutes for medium-rare. Transfer the steaks to a cutting board and cover loosely with aluminum foil.

Step 5

Pour off the excess fat from the skillet, place over medium heat, and melt the remaining 2 Tbs. butter. Add the shallots and cook, stirring occasionally, until translucent, about 3 minutes. Add the broth and bring to a simmer. Add the wine and simmer until reduced by half, about 5 minutes. Remove from the heat, stir in the crème fraîche and season with salt and pepper. Stir in the mushrooms, reheating over medium heat until warmed through if needed.

Step 6

Unwrap the herb butter and cut into thin slices. Arrange the steaks, sliced thinly across the grain or whole, on a serving platter or individual plates. Top with the mushroom sauce and the herb butter and serve immediately. Serves 4.
