Step 1: Preheat Your Oven - Start by preheating your oven to 375°F (190°C). This ensures that your salmon cooks evenly and achieves that beautiful caramelized finish.
Step 2: Prepare the Foil - Lay out two large pieces of aluminum foil on a baking sheet. You want enough foil to wrap the salmon tightly, so don’t skimp here!
Step 3: Make the Glaze - In a mixing bowl, combine the melted butter, brown sugar, lemon juice, Dijon mustard, garlic powder, onion powder, salt, and dried thyme. Whisk until everything is well blended and you have a smooth glaze.
Step 4: Place the Salmon - Lay the salmon fillets on the foil, skin-side down if applicable. Spoon the glaze generously over each fillet, ensuring they are well coated.
Step 5: Add Lemon Slices - Place the lemon slices on top of the salmon. The lemons will add a refreshing zing and aromatic quality as the salmon bakes.
Step 6: Wrap It Up - Fold the sides of the foil over the salmon, then seal the top tightly, creating a packet. This locks in steam and flavors during baking.
Step 7: Bake - Place the baking sheet in the preheated oven and bake for about 20-25 minutes, or until the salmon flakes easily with a fork. The cooking time may vary slightly based on the thickness of your fillets.
Step 8: Serve - Once done, carefully unwrap the foil (watch out for the steam) and transfer the salmon to a serving platter. Garnish with fresh parsley for a pop of color and extra flavor.
