Ingredients

  • 16 oz New York strip steak (1 inch thick), patted dry
  • 1 lb russet potatoes, cut into 1/4-in sticks
  • 2 tbsp green peppercorns in brine, drained and lightly crushed
  • 1 large shallot, minced
  • 1/4 cup cognac or brandy
  • 1/2 cup heavy cream
  • 1/2 cup low-sodium beef stock
  • 2 tbsp unsalted butter
  • 2 tbsp vegetable oil (or other high-heat oil)
  • 1 cup vegetable oil (for frying potatoes)
  • 2 tsp kosher salt
  • 1 tsp black pepper, coarsely ground
  • 1 tsp Dijon mustard
  • 2 tbsp fresh flat-leaf parsley, chopped

Instructions

  1. 1

    Soak 1 lb cut into 1/4-in sticks russet potatoes in cold water for 30 minutes; drain and pat completely dry. This removes excess starch for crispier fries.

  2. 2

    Heat 1 cup vegetable oil (for frying potatoes) in a large, heavy skillet or Dutch oven to 325°F. Fry potatoes in batches for 3-4 minutes until tender but not colored. Remove and drain on a rack. Let oil return to 375°F, then fry again until golden and crisp, 2-3 minutes. Drain, season with salt, and keep warm.

  3. 3

    Season 16 oz New York strip steak (1 inch thick) (patted dry) generously on both sides with 2 tsp kosher salt and 1 tsp coarsely ground black pepper. Heat a separate cast-iron or heavy skillet over high heat until smoking. Add 2 tbsp vegetable oil (or other high-heat oil).

  4. 4

    Sear the steak undisturbed for 3-4 minutes per side for medium-rare (internal temperature of 130-135°F / 54-57°C). In the last 2 minutes, add 2 tbsp unsalted butter and baste the steak repeatedly. Transfer to a plate and rest for 5 minutes.

  5. 5

    In the same pan, reduce heat to medium. Cook 1 large minced shallot in the pan drippings for 1 minute. Add 1/4 cup cognac or brandy and carefully tilt the pan away from you - the alcohol may briefly flame. Let it reduce by half, about 1 minute.

  6. 6

    Add 1/2 cup low-sodium beef stock and scrape up any browned bits. Stir in 1/2 cup heavy cream, 2 tbsp drained and lightly crushed green peppercorns in brine, and 1 tsp Dijon mustard. Simmer until the sauce coats the back of a spoon, about 3-4 minutes. Taste and adjust seasoning.

  7. 7

    Slice the rested steak against the grain. Plate alongside the fries. Spoon peppercorn sauce over the steak and garnish with 2 tbsp chopped fresh flat-leaf parsley.

Questions

Can I make Steak Frites with Peppercorn Sauce dairy-free?

Yes. The dairy in this entry is 1/2 cup heavy cream, 2 tbsp unsalted butter. Swap the cream for full-fat coconut milk or an oat cooking cream; the butter for olive oil where it melts, or a plant-based block butter where it is creamed. The richness shifts slightly, but the method does not change.

How long does Steak Frites with Peppercorn Sauce keep?

Refrigerate leftovers within two hours and eat them within three days. Reheat gently on the stovetop.

Can I halve or double Steak Frites with Peppercorn Sauce?

Yes. As written it serves 2. Every ingredient in this entry carries precomputed half and double quantities, and the app's batch dial rewrites them inside each step. When doubling on the stovetop, use your widest pan or work in two batches so the food sears instead of steaming.
