Instructions

  1. Adjust rack to top position and preheat oven to 450°F. Wash and dry all produce. Pat steak dry with paper towels; season all over with salt and pepper. Let sit at room temperature until ready to cook.
  2. Cut potatoes into ½-inch-thick wedges. Toss on one side of a baking sheet with a large drizzle of olive oil, half the Fry Seasoning, salt and pepper. Roast 10 minutes.
  3. Meanwhile, halve, peel and dice shallot. Peel and halve carrots lengthwise; cut into strips the size of green beans. Toss in a medium bowl with green beans, a large drizzle of olive oil, salt and pepper. Once potatoes have roasted 10 minutes, add carrots and beans to empty side of sheet. Continue roasting until potatoes are crispy and veggies are tender, 15-20 minutes.
  4. Meanwhile, melt ½ tablespoon butter in a large pan over medium-high heat. Add almonds and cook, stirring, for 1 minute. Add ¼ teaspoon sugar and a pinch of salt. Continue cooking until toasted, 1-2 minutes more. Turn off heat; transfer to a plate. Wipe out pan. In a second medium bowl, combine stock concentrate, mustard and ¼ cup water.
  5. Heat a drizzle of olive oil in same pan over medium-high heat. Add steak and cook until a crust has formed on the first side, 3-6 minutes. Flip steak, lower heat to medium and add half the Herbes de Provence and 1 tablespoon butter. Cook until steak reaches desired doneness, 3-6 minutes more. Transfer to a plate and let rest. Wipe out pan.
  6. Melt ½ tablespoon butter in same pan over medium heat. Add shallot; cook 1 minute. Add stock mixture; reduce heat to low. Cook 1 minute. Add sour cream and any resting juices from steak. Cook until thickened, 1 minute. Stir in 1 tablespoon butter. Slice steak against the grain. Divide steak, potatoes and veggies between plates. Top steak with sauce. Top veggies with almonds.

Recipe Tips

Let the steak rest before slicing to keep it juicy.

For extra crispy potatoes, make sure they are in a single layer on the baking sheet.

Toast almonds just until golden to avoid burning.
