This Salmon Wellington is an elegant yet approachable dish featuring tender salmon fillets wrapped in golden, flaky puff pastry with a savory filling of fresh spinach, garlic, thyme, and Parmesan cheese. A buttery Dijon mustard and lemon glaze adds a bright, zesty flavor that perfectly complements the rich salmon. Beautiful enough for a special occasion but simple enough for a weeknight dinner, this recipe is sure to impress around the table. Best of all, the Wellingtons can be prepared ahead of time, making it easy to enjoy a delicious, restaurant-worthy meal at home.
