Cooking Steps

Prep & Roast Garlic
1
  • Adjust rack to middle position (middle and top positions for 4 servings) and preheat oven to 450 degrees. Wash and dry produce.

  • Dice potatoes into ½-inch pieces. Roughly chop parsley. Trim and discard bottom 1 inch from asparagus.

  • Place garlic cloves in the center of a small piece of foil; drizzle with oil and season with salt and pepper. Cinch into a packet and place on a baking sheet. Roast on middle rack for 10 minutes (you’ll add more to the sheet then).

Cook Potatoes & Make Crust
2
  • Meanwhile, place potatoes in a medium pot with enough salted water to cover by 2 inches. Bring to a boil and cook until tender, 15-20 minutes. Reserve ½ cup potato cooking liquid (¾ cup for 4 servings), then drain. Return potatoes to pot and cover to keep warm.

  • While potatoes cook, combine panko, parsley, half the Parmesan (you’ll use the rest later), 1 TBSP olive oil (2 TBSP for 4), and a pinch of salt and pepper in a medium bowl.

Prep Salmon
3
  • Pat salmon* dry with paper towels and season all over with salt and pepper. Place on a plate; drizzle skin sides with oil; rub to coat. Place, skin sides down, on plate.

  • Evenly spread tops with a thin layer of half a packet of mustard (whole packet for 4 servings). Mound tops with panko mixture, pressing firmly to adhere.

Roast Salmon & Asparagus
4
  • Once garlic has roasted 10 minutes, remove sheet from oven. Carefully add salmon to one side of sheet. Toss asparagus on empty side with a drizzle of oil, salt, and pepper.

  • Return to middle rack and roast until asparagus and garlic are tender, and salmon is golden brown and cooked through, 10-12 minutes. (For 4 servings, toss asparagus on a second sheet; roast asparagus on middle rack and salmon on top rack.)

Mash Potatoes
5
  • To pot with potatoes, add roasted garlic with its oil, half the cream sauce base, remaining Parmesan, and 1 TBSP butter (2 TBSP for 4 servings). Mash with a potato masher or fork until smooth and creamy, adding splashes of reserved potato cooking liquid as needed. Taste and season with salt and pepper.

Make Sauce
6
  • Heat a small pan over medium-high heat. Add half the vinegar (save the rest for another use), remaining cream sauce base, remaining mustard, and 1 tsp sugar (2 tsp for 4 servings). Cook, stirring occasionally, until sauce begins to thicken, 2-4 minutes. Remove from heat and stir in 1 TBSP butter (2 TBSP for 4).

  • Taste and season with salt and pepper.

Serve
7
  • Divide salmon, asparagus, and mashed potatoes between plates. Drizzle salmon with creamy mustard sauce and serve.
