You don’t need to go to a French restaurant for authentic steak au poivre. Everyday Food editor Sarah Carey teaches you how to make this bistro favorite at home.
Preheat oven to 425 degrees. Place potatoes on a rimmed baking sheet and toss with 1 tablespoon oil; season with salt. Roast until golden brown and crisp, about 35 minutes, flipping halfway through.
Meanwhile, spread peppercorns on a large plate. Season steaks with salt, then press into pepper, coating both sides. In a large skillet, heat 1 tablespoon oil and butter over high. In 2 batches, cook steaks until medium rare, about 8 minutes, flipping once. Let rest on a cutting board, 5 to 10 minutes.
Discard fat from skillet, lightly wipe with a paper towel to remove any loose pepper, and heat over medium. Add wine and cook, stirring and scraping up browned bits with a wooden spoon, until wine is reduced by half, about 2 minutes. Add cream and cook until sauce coats back of spoon, about 4 minutes. Stir in mustard and season with salt.
Refrigerate 1 steak to use in the Steak Sandwich Wrap. Slice remaining steaks against the grain, divide among four plates, and top with sauce. Serve with potatoes and parsley.
