SALMON EN CROUTE

Steps:

• 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.
• 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.
• Preheat oven to 350 degrees F (175 degrees C). Line a glass baking dish with parchment paper.
• 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. Cover with second puff pastry sheet. Fold over and crimp edges to seal.
• Brush top with beaten egg. Transfer to baking dish.
• Bake in the preheated oven until pastry is golden, 40 to 45 minutes. Remove and let stand for 5 minutes. Slice into 4 portions.
• Whisk mayonnaise, lemon juice, Dijon mustard, and dill together in a small bowl. Spoon sauce onto 4 plates and place a piece of salmon on each.
• Note: You can substitute spinach with asparagus spears. Use 1 heaping teaspoon fresh dill instead of the dried if preferred.
• Note: Use espelette pepper instead of the smoked paprika if you can find it.
• Note: If using a convection oven, bake for 30 to 35 minutes.
