This dish is a little piece of spring on your plate! Sweet tender salmon, earthy spring vegetables and plenty of herbs make this the perfect weeknight dinner.

Ingredient

• Kosher salt and freshly ground black pepper
• 1/2 cup panko 
• 1/2 cup loosely packed fresh flat-leaf parsley leaves and tender stems 
• 1 sprig fresh tarragon leaves, plus 2 tablespoons coarsely chopped fresh tarragon 
• 2 tablespoons olive oil 
• 2 teaspoons brown sugar 
• 2 teaspoons Dijon mustard 
• 3 tablespoons fresh lemon juice, plus lemon wedges for serving 
• Four 6-ounce skinless center-cut salmon fillets (about 1 1/2 inches thick) 
• 1 pound thin asparagus, trimmed and cut into 1 1/2-inch pieces 
• 2 cups shelled English peas or thawed frozen peas (about 10 ounces) 
• 2 tablespoons unsalted butter 
• 4 radishes, thinly sliced (about 4 ounces) (see Cook’s Note)

Direction

1. Preheat the oven to 425 degrees F and line a baking sheet with aluminum foil.
2. Bring 8 cups of salted water to a boil in a covered large saute pan. Fill a large bowl with ice water and set a mesh strainer on top of the ice.  
3. Pulse the panko, parsley, the leaves from 1 sprig fresh tarragon and 1/4 teaspoon each salt and pepper in a mini food processor until the herbs are coarsely chopped. Drizzle in 1 tablespoon of the oil and pulse until the mixture is combined. Transfer to a plate.  
4. Combine the brown sugar, mustard, 1 tablespoon of the lemon juice and remaining 1 tablespoon oil in a small bowl. Brush the tops and sides of the salmon generously with the mustard mixture and sprinkle with salt and pepper. Press a salmon fillet, top-side down, into the panko mixture. Place, panko-side up, on the prepared baking sheet. Repeat with the remaining fillets and bake until the panko is toasted and the salmon is just cooked through, 8 to 10 minutes.  
5. Meanwhile, put the asparagus and peas in the saute pan of boiling water and cook until almost crisp-tender, about 3 minutes. Transfer the vegetables to the prepared ice bath with a slotted spoon and let cool, about 1 minute. 
6. Meanwhile, heat a second large saute pan over medium-high heat and add the butter, swirling, until melted. Drain the cooled vegetables and add to the pan. Season with salt and pepper. Cook, stirring occasionally, until tender, 3 to 5 minutes. Remove from the heat, add the radishes, the remaining 2 tablespoons lemon juice and 2 tablespoons tarragon. Toss to combine, taste and adjust the seasoning. Serve the salmon with the asparagus salad and a lemon wedge.
