Coating fish with nuts and baking it is an easy, foolproof way to cook it elegantly. And it is especially nice with a mild white fish like cod or halibut. The spinach turns a little yellowy because it's cooked with the acidic lemon juice, but what you lose in green color is more than made up for in great flavor.

Ingredients

  • Zest and juice of 1 medium lemon, divided

  • ½ cup sliced almonds, coarsely chopped

  • 1 tablespoon finely chopped fresh dill or 1 teaspoon dried dill

  • 1 tablespoon plus 2 teaspoons extra-virgin olive oil, divided

  • 1 teaspoon kosher salt, divided

  • Freshly ground pepper to taste

  • 1 1/4 pounds cod (see Tip) or halibut, cut into 4 portions

  • 4 teaspoons Dijon mustard

  • 2 cloves garlic, slivered

  • 1 pound baby spinach

  • 4 Lemon wedges for garnish

Method

  1. Preheat oven to 400 degrees F. Coat a rimmed baking sheet with cooking spray.

  2. Combine lemon zest, almonds, dill, 1 tablespoon oil, 1/2 teaspoon salt and pepper in a small bowl. Place fish on the prepared baking sheet and spread each portion with 1 teaspoon mustard. Divide the almond mixture among the portions, pressing it onto the mustard.

  3. Bake the fish until opaque in the center, about 7 to 9 minutes, depending on thickness.

  4. Meanwhile, heat the remaining 2 teaspoons oil in a Dutch oven over medium heat. Add garlic and cook, stirring, until fragrant but not brown, about 30 seconds. Stir in spinach, lemon juice and the remaining 1/2 teaspoon salt; season with pepper. Cook, stirring often, until the spinach is just wilted, 2 to 4 minutes. Cover to keep warm. Serve the fish with the spinach and lemon wedges, if desired.
