Salmon and asparagus foil packets are a quick and easy meal that requires minimal cleanup. This recipe combines salmon fillets with fresh asparagus, lemon slices, and a flavorful herb butter. The salmon and asparagus are placed on a sheet of aluminum foil, then topped with the herb butter, which is made by combining melted butter, minced garlic, chopped fresh herbs, and a pinch of salt. The foil packets are sealed and baked in the oven until the salmon is flaky and the asparagus is tender. Serve this dish with a side of quinoa or roasted potatoes for a complete and hassle-free meal.
