Roast potatoes
  • Cut potatoes into 2-inch pieces.
  • Add potatoes and 2 tsp (4 tsp) oil to a parchment-lined baking sheet. Season with salt and pepper, then toss to coat.
  • Roast in the middle of the oven, stirring halfway through, until tender and golden-brown, 18-22 min.
Prep and toast almonds
  • Meanwhile, heat a large non-stick pan over medium heat. 
  • While the pan heats, thinly slice mushrooms.
  • Add almonds to the dry pan. Toast, stirring occasionally, until golden, 4-5 min. (TIP: Keep your eye on them so they don't burn!) 
  • Transfer almonds to a plate.
  • Trim and discard bottom 1-inch from asparagus.
  • Thinly slice chives.
  • Peel, then mince or grate garlic.
Cook steak
  • Meanwhile, reheat the same pan (from step 1) over medium-high.
  • While the pan heats, pat steak dry with paper towels. Season with salt and pepper.
  • When the pan is hot, add 1 tbsp (2 tbsp) oil, then steak. Sear until golden-brown, 1-2 min per side.
  • Remove the pan from heat, then transfer steak to an unlined baking sheet.
  • Roast in the top of the oven until cooked to desired doneness, 6-8 min.**
  • Transfer steak to a clean cutting board. Set aside to rest for 2-3 min.
Cook mushroom sauce
  • Meanwhile, heat a medium pot over medium-high heat.
  • When hot, add 1 1/2 tbsp (3 tbsp) butter, then swirl the pot until melted.
  • Add mushrooms. Season with salt and pepper. Cook, stirring occasionally, until mushrooms are golden, 4-5 min.
  • Sprinkle Cream Sauce Spice Blend and half the garlic over mushrooms. Cook, stirring often, until fragrant, 30 sec.
  • Remove the pan from heat. Add cooking wine, whisking until slightly reduced, 20 sec.
  • Return the pan to medium, then whisk in broth concentrate, cream and 1/4 cup (1/2 cup) water until smooth.
  • Bring to a simmer, whisking occasionally, until slightly thickened, 3-4 min.
Cook asparagus
  • Meanwhile, reheat the same pan (from step 3) over medium-high.
  • When hot, add 1/2 tbsp (1 tbsp) oil, then asparagus. Cook, stirring occasionally, until tender-crisp, 4-5 min. 
  • Add remaining garlic. Cook, stirring often, until fragrant, 30 sec.
  • Season with salt and pepper.
Finish and serve
  • Add half the Worcestershire sauce (use all for 4 ppl) to the pot with mushroom sauce. Season with salt and pepper, then stir to combine.
  • Add half the chives and 1/2 tbsp (1 tbsp) butter to the baking sheet with potatoes. Toss until butter melts and coats potatoes.
  • Thinly slice steak.
  • Divide potatoes, steak and asparagus between plates.
  • Spoon mushroom sauce over steak.
  • Sprinkle almonds over asparagus.
  • Sprinkle remaining chives over plate.
