Description

This dish is a celebration of simplicity and fresh flavors, perfect for a breezy weeknight dinner or a light summer lunch. The white fish fillets become incredibly tender and flaky when roasted, absorbing the tangy punch of Dijon mustard and the aromatic brightness of fresh dill. Paired with a quick sauté of spinach and garlic, the meal offers a wonderful contrast in textures—crisp greens against soft, moist fish. It’s naturally light yet deeply satisfying, requiring minimal effort for maximum impact. Serve it family-style with crusty bread to soak up the lemony juices, or plate it individually for an elegant presentation that feels effortless. The combination of citrus, herbs, and mustard creates a sophisticated profile without overwhelming the delicate taste of the fish.

Ingredients

Directions

  1. Preheat oven to 450°F. Spray a glass baking dish with nonstick vegetable oil spray.
  2. Arrange the fish fillets in the prepared dish. Sprinkle evenly with 1 tablespoon of fresh lemon juice.
  3. Spread 1 teaspoon of Dijon mustard over each fillet, ensuring full coverage.
  4. Sprinkle 7 tablespoons of chopped dill over the mustard-coated fish.
  5. Bake until the fish fillets are just cooked through and opaque, about 10 minutes.
  6. While the fish bakes, heat olive oil in a large nonstick skillet over medium heat.
  7. Add the spinach and minced garlic to the skillet. Stir just until the spinach is wilted, about 3 minutes.
  8. Using tongs, transfer the spinach to a serving platter, leaving the pan juices behind. Top the spinach with the hot fish fillets.
  9. Garnish with the remaining 1 tablespoon of chopped dill and lemon wedges. Serve immediately.

Note

Storage: Store leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently to avoid overcooking the fish.

Substitutions: If fresh dill is unavailable, use dried dillweed, but reduce the quantity by half as the flavor is more concentrated. Any firm white fish fillet works well here.

Tips: For extra richness, drizzle a little extra virgin olive oil over the spinach after sautéing. Ensure spinach is thoroughly drained to prevent a watery dish.

Variations: Add sliced cherry tomatoes to the spinach for a burst of sweetness and color.
