Description

Salmon en croûte is easy to make by wrapping a salmon fillet, tender mushrooms, and spinach in puff pastry and baking until the crust is golden and delicious.

Ingredients

2 tablespoons olive oil, divided
1/2 onion, chopped
1 cup chopped fresh mushrooms
2 teaspoons minced garlic, divided
salt and ground black pepper to taste
1 cup baby spinach
1 tablespoon all-purpose flour, or as needed
2 sheets frozen puff pastry (such as Pepperidge Farm®), thawed
1 (1 1/2-pound) boned, skinned salmon fillet
1/2 teaspoon smoked paprika, or more to taste
1 egg, beaten
1/2 cup mayonnaise
2 tablespoons fresh lemon juice
2 teaspoons Dijon mustard
1/2 teaspoon dried dill

Directions

1 Gather all ingredients.
2 Heat 1 tablespoon oil in a large skillet over medium heat. Add onion; cook and stir until translucent, about 5 minutes. Add mushrooms and 1 teaspoon garlic; cook and stir until mushrooms are soft, about 5 minutes. Season with salt and black pepper. Transfer onion and mushroom mixture to a small bowl.
3 Heat remaining 1 tablespoon oil in the same skillet. Add remaining 1 teaspoon garlic; cook and stir until fragrant, about 30 seconds. Add spinach; cook and stir until wilted, 3 to 5 minutes. Season with salt and black pepper. Transfer to another bowl.
4 Preheat oven to 350 degrees F (175 degrees C). Line a glass baking dish with parchment paper.
5 Dust work surface with flour. Lay 1 puff pastry sheet out on work surface; spread onion and mushroom mixture evenly across pastry, leaving a 1/2-inch border. Center salmon on top; sprinkle paprika over salmon and top with wilted spinach.
6 Cover with second puff pastry sheet. Fold over and crimp edges to seal. Brush top with beaten egg. Transfer to prepared baking dish.
7 Bake in the preheated oven until pastry is golden, 40 to 45 minutes. Let cool briefly, then slice into 4 portions.
8 To make the sauce: Whisk mayonnaise, lemon juice, Dijon mustard, and dill together in a small bowl.
9 Spoon sauce onto 4 plates and place a piece of salmon en croûte on each.
