Preheat Oven: Preheat your oven to 375°F (190°C).

Prepare Lemons: Slice 1 1/2 lemons into thin rounds. Reserve the remaining 1/2 lemon for later.

Set Up Sheet Pan: Line a sheet pan with foil. Place the salmon fillet skin-side down in the center. Fold the edges of the foil up around the salmon to create a "boat" shape.

Make Garlic Butter: In a small saucepan, melt the butter over medium heat. Add minced garlic and the seasonings. Cook for 30 seconds, stirring occasionally.

Brush the Salmon: Brush 3/4 of the garlic butter mixture generously over the salmon fillet, reserving the rest for later.

Add Lemon Slices: Arrange the lemon slices evenly over the top of the salmon.

Seal the Foil Packet: Place another piece of foil over the salmon and pinch the edges together with the bottom foil to create a sealed packet.

Optional - Add Vegetables: If desired, add vegetables like zucchini, yellow squash, asparagus, or broccoli around the salmon on the sheet pan. Drizzle with olive oil and season with salt and pepper to taste.

Bake: Bake the salmon in the preheated oven for 17-20 minutes, depending on the thickness of the fillet.

Broil for Browning: Turn on the broiler. Remove the top piece of foil from the salmon and broil for an additional 3-4 minutes to lightly brown the top.

Finish and Garnish: Remove the lemon slices from the salmon. Squeeze the reserved 1/2 lemon over the fillet and drizzle with the remaining garlic butter, if desired. Garnish with freshly chopped parsley.

Serve: Serve the salmon with the roasted vegetables and rice for a complete meal. Enjoy!
