Lemon Garlic Salmon Tray Bake – Easy & Healthy!

This recipe is basically the cooking equivalent of finding a twenty-dollar bill in your old jacket pocket – surprisingly delightful and way easier than you expected.

Picture this: flaky salmon with a golden, garlicky crust that makes your kitchen smell like a fancy restaurant, paired with perfectly tender asparagus and cherry tomatoes that burst with sweet, caramelized flavor.

The best part is watching people’s faces when they realize you made something this impressive in just 11 minutes of actual cooking time – no sweating over multiple pans or timing disasters.

That lemon garlic marinade doesn’t just sit on top; it actually penetrates the salmon, creating layers of bright, zesty flavor that complement the rich, buttery fish perfectly.

Plus, everything cooks on one sheet pan under the broiler, which means minimal cleanup and maximum flavor development as all those delicious juices mingle together.

This is the kind of recipe that makes you look like you have your culinary life together, even if you’re just winging it in yesterday’s pajamas.

Ingredients

For the Salmon

• 4 x 180g/6 oz salmon fillets, skin on or off

Marinade Slather

• 1 tsp lemon zest (from 1 lemon)
• 1 tbsp fresh lemon juice
• 2 tbsp extra virgin olive oil
• 1 tsp Dijon mustard
• 2 garlic cloves, grated using microplane
• 1 /2 tsp kosher salt
• 1 /4 tsp black pepper

Vegetables (optional but recommended)

• 3 bunches asparagus, woody ends trimmed
• 200 g/7 oz cherry tomatoes
• 2 tsp extra virgin olive oil
• 1 /4 tsp each salt and pepper

For Cooking & Serving

• Olive oil spray
• Parmesan cheese, finely grated
• Lemon wedges for serving
• Fresh parsley, finely chopped (optional)
• Crusty bread or toast for serving

Instructions

Prepare the Marinade

1. 1 Mix the lemon zest, 1 tbsp lemon juice, 2 tbsp olive oil, Dijon mustard, grated garlic, 1/2 tsp salt, and 1/4 tsp pepper in a small bowl until well combined. The mixture should form a thick, fragrant paste that coats the back of a spoon.
2. 2 Slather this aromatic mixture generously onto the top and sides of each salmon fillet, massaging it gently into the flesh. If you have time, let the salmon marinate for 1 hour in the refrigerator – this allows the flavors to penetrate deeper, but you can proceed immediately if needed.

Set Up for Broiling

1. 3 Preheat your oven’s broiler to 280°C/525°F or as high as your oven will go. Position the oven rack 20cm/8 inches from the heat source – this distance is crucial for achieving that perfect golden crust without overcooking the interior.

Prepare the Vegetables

1. 4 In a large bowl, toss the asparagus spears and cherry tomatoes with 2 tsp olive oil, 1/4 tsp salt, and 1/4 tsp pepper until evenly coated. The vegetables should glisten with oil but not be swimming in it.
2. 5 Spread the seasoned vegetables across a large sheet pan in a single layer, then clear distinct spaces for each salmon fillet. This prevents overcrowding and ensures even cooking.

Cook the Tray Bake

1. 6 Place the marinated salmon fillets in the cleared spaces on the tray, leaving about 2 inches between each piece for proper air circulation. Lightly spray the surface of each salmon fillet with olive oil spray to promote browning.
2. 7 Broil for 11 minutes without opening the oven door. The salmon is perfectly done when the flesh flakes easily with a fork and reaches an internal temperature of 50°C/122°F. The asparagus should be tender-crisp, and the tomatoes should be blistered and slightly caramelized.

Finish and Serve

1. 8 Carefully transfer the salmon and vegetables to serving plates using a wide spatula. Immediately grate fresh Parmesan cheese over the warm vegetables – the residual heat will slightly melt the cheese for maximum flavor impact.
2. 9 Squeeze fresh lemon juice over each salmon fillet, sprinkle with chopped parsley if desired, and serve alongside crusty bread for soaking up any delicious pan juices.

Pro Tips and Troubleshooting

Professional Techniques

Always pat salmon dry before applying marinade – this ensures better adhesion and prevents steaming. Score the skin lightly if keeping it on to prevent curling. Room temperature fish cooks more evenly, so remove from refrigerator 15 minutes before cooking.

Common Mistake Prevention

Don’t overcrowd the pan – vegetables need space to roast rather than steam. Watch the broiler closely after 8 minutes, as broilers vary significantly in intensity. Avoid flipping the salmon – the high heat cooks it perfectly from one side.

Storage and Reheating

Refrigerate leftovers for up to 3 days in airtight containers. Reheat gently in a 300°F (150°C) oven for 8-10 minutes to prevent overcooking. The salmon is also delicious served cold over salads.

Make-Ahead Strategies

Marinate salmon up to 4 hours ahead for deeper flavor. Prep vegetables in the morning and store covered at room temperature. Mix the marinade up to 2 days in advance.

Scaling Tips

This recipe doubles easily – just use two sheet pans to avoid overcrowding. For larger crowds, consider cutting salmon into smaller portions for more even cooking and easier serving.

This lemon garlic salmon tray bake proves that the best recipes are often the simplest ones – minimal effort, maximum flavor, and the kind of results that make you look like a kitchen genius without breaking a sweat.
