Step-by-Step Instructions for Sheet Pan Lemon Garlic Butter Salmon

Preparing this dish is about combining simplicity with attention to detail. While the method is straightforward, the success of the final result hinges on small touches—like how the butter is melted, how the garlic is minced, or how the salmon is placed on the pan. Let’s break down the entire process meticulously.

Step 1: Gather and Prepare Your Ingredients

Preparation Time: 10–15 minutes
Before you begin cooking, it’s crucial to gather all your ingredients and have them prepped and ready. This concept is known in the culinary world as mise en place—everything in its place. It ensures a smooth cooking process and prevents last-minute scrambling.

Ingredients:

• Salmon Fillets (4 pieces, about 6 oz each) – Choose skin-on, fresh or thawed fillets. Wild-caught varieties like Sockeye or Coho offer robust flavor, while Atlantic salmon is milder and more forgiving during cooking.

• Fresh Garlic (4–6 cloves) – Finely minced or pressed to release maximum flavor.

• Lemon (2 whole lemons) – One sliced into thin rounds; the other juiced for the butter sauce.

• Unsalted Butter (½ cup or 1 stick) – Cut into small cubes or melted for the sauce.

• Olive Oil (2 tbsp) – For drizzling over vegetables and greasing the pan.

• Fresh Herbs (optional: parsley, dill, or thyme) – Chopped, for garnishing and aromatic flavor.

• Salt (to taste) – Use kosher salt or sea salt for better texture and seasoning.

• Freshly Ground Black Pepper (to taste)

• Vegetables (your choice, totaling about 4 cups)
  Recommended:

  • Baby potatoes, halved

  • Broccoli florets

  • Asparagus spears

  • Cherry tomatoes

  • Red onion wedges

Step 2: Preheat the Oven

Time: 5–10 minutes
Set your oven to 400°F (200°C). This temperature is ideal for roasting both salmon and vegetables evenly. It allows the salmon to cook through while preserving moisture and enabling vegetables to caramelize at the edges without burning.

If your oven tends to run hot or cool, consider using an oven thermometer for accuracy.

Step 3: Prepare the Sheet Pan

Time: 2 minutes
Line a large, rimmed sheet pan (also known as a half-sheet pan) with parchment paper or aluminum foil. This prevents sticking and makes cleanup significantly easier. If using foil, lightly grease it with a teaspoon of olive oil or non-stick spray.

Make sure your pan is large enough to allow space between the vegetables and the salmon fillets. Overcrowding leads to steaming rather than roasting.

Step 4: Prepare the Lemon Garlic Butter Sauce

Time: 5 minutes
In a small saucepan or microwave-safe bowl, combine the following:

• ½ cup unsalted butter

• Juice of 1 lemon (about 2 tablespoons)

• 4–6 cloves of garlic, finely minced

• ½ teaspoon salt

• ¼ teaspoon black pepper

• Optional: ½ teaspoon crushed red pepper flakes for heat

Melt the butter gently over low heat if using the stovetop, or in 30-second increments in the microwave. Stir well to combine. This sauce will serve as both a marinade and basting liquid.

Pro Tip: If you prepare the sauce ahead of time and let it sit for a few minutes, the garlic will infuse more deeply into the butter, intensifying the flavor.

Step 5: Season and Arrange the Vegetables

Time: 5–7 minutes
Place your prepped vegetables in a large mixing bowl. Drizzle with olive oil (about 2 tablespoons), season with salt and pepper, and toss well to coat.

Transfer the seasoned vegetables onto the sheet pan, spreading them out in a single, even layer. Keep a space in the center or along one side clear for the salmon fillets.

Vegetable Cooking Tips:

• If using baby potatoes or other dense vegetables, parboil them for 5–7 minutes in boiling water before roasting. This ensures they cook through at the same rate as the salmon.

• Avoid cutting vegetables too large—they should be bite-sized to cook quickly and evenly.

Step 6: Season the Salmon

Time: 3–5 minutes
Place your salmon fillets skin-side down on the prepared sheet pan.

Brush or spoon the lemon garlic butter generously over each piece of salmon. Make sure some garlic lands directly on the fillets, and let the sauce run onto the pan—this will flavor the vegetables during roasting.

Sprinkle with a pinch of salt, freshly ground black pepper, and any fresh herbs you’re using. Lay 1–2 lemon slices over each fillet for visual appeal and added citrus aroma.

Optional: For more intense flavor, you can marinate the salmon in the lemon garlic butter for 15–30 minutes prior to cooking.

Step 7: Roast Everything Together

Time: 15–18 minutes (depending on salmon thickness)
Place the sheet pan in the center rack of your preheated oven. Roast at 400°F for about 15 minutes, checking for doneness starting at the 12-minute mark.

How to tell when salmon is done:

• The flesh should flake easily with a fork.

• It should appear opaque and moist, not raw or translucent in the thickest part.

• An instant-read thermometer inserted into the thickest part should read 125–130°F for medium, or 140°F if you prefer it fully cooked.

If the vegetables are undercooked at the 15-minute mark, you can remove the salmon, cover it loosely with foil to keep warm, and return the vegetables to the oven for an additional 5–10 minutes.

Tip for crispier edges: Broil the sheet pan on high for the last 2 minutes of cooking, but watch carefully to avoid burning.

Step 8: Rest and Garnish

Time: 2–3 minutes
Once the salmon is cooked, remove the sheet pan from the oven and let the salmon rest for a couple of minutes. This allows the juices to redistribute within the fillets, keeping them moist and tender.

Garnish with freshly chopped parsley or dill, an extra drizzle of lemon juice, and a few grinds of black pepper. Optionally, add lemon zest over the top for a bright, aromatic finish.

Step 9: Serve

Serve the salmon fillets with a generous helping of the roasted vegetables. This dish pairs beautifully with a side of:

• Herbed rice or quinoa

• Crusty bread to soak up extra garlic butter

• A simple green salad with vinaigrette

• Couscous or orzo tossed with olive oil and lemon
