Step 1

• Adjust rack to top position (top and middle positions for 4 servings) and preheat oven to 425 degrees. Wash and dry produce. • Cut potatoes into 1/4-inch-thick rounds. Peel and mince or grate garlic. Trim and discard woody bottom ends from asparagus. Halve, peel, and mince shallot. Pick and finely chop fronds from dill. Zest and quarter lemon.

Step 2

• In a large bowl, toss potatoes with 2 TBSP oil (4 TBSP for 4 servings), garlic, and a couple big pinches of salt and pepper until thoroughly coated. • Arrange potatoes on one side of a baking sheet in a single overlapping layer (for 4, layer potatoes across entire sheet). TIP: Be sure to shingle the potatoes in a single layer so they cook evenly. • Roast on top rack for 15 minutes (you’ll add the asparagus then).

Step 3

• Once potatoes have roasted 15 minutes, remove sheet from oven. Carefully add asparagus to empty side; toss with a drizzle of olive oil, salt, and pepper. (For 4 servings, leave potatoes roasting; add asparagus to a second baking sheet and roast on middle rack.) • Return sheet to oven until asparagus is slightly softened and potatoes are browned and tender, 10-12 minutes more.

Step 4

• While asparagus and potatoes roast, pat trout* dry with paper towels and season all over with salt and pepper. • Heat a drizzle of oil in a large pan over medium heat. Add trout to pan skin sides down. Cook until skin is crispy, 5-6 minutes. • Flip trout; continue cooking until opaque and cooked through, 4-6 minutes more. Turn off heat; transfer to a plate and wipe out pan.

Step 5

• Heat a drizzle of oil in same pan over medium-high heat. Add shallot; cook, stirring, until slightly softened, 2-3 minutes. • Stir in mustard, stock concentrate, honey, and 1/4 cup water (1⁄3 cup water for 4 servings). Simmer until slightly thickened, 2-3 minutes. • Turn off heat. Stir in sour cream, half the chopped dill, juice from one lemon wedge, and 1 TBSP butter until everything is incorporated. (For 4, all the chopped dill, juice from two lemon wedges, and 2 TBSP butter.) Season with salt and pepper.

Step 6

• Carefully toss asparagus with a pinch of lemon zest to taste. • Divide potatoes, asparagus, and trout between plates. Spoon half the sauce over trout. Serve with remaining sauce and remaining lemon wedges on the side. Trout is fully cooked when internal temperature reaches 145°.
