This lemon garlic butter salmon is tender, flaky and ready in approximately 20 minutes. Melted butter, fresh garlic, lemon juice and herbs create a bright, savoury sauce without covering the natural flavour of the fish.
Baking is one of the easiest ways to cook salmon because it requires minimal attention and produces consistent results. Individual fillets also cook quickly, making this recipe suitable for busy weeknights.
Serve the salmon with roasted potatoes, rice, green beans, asparagus or a simple salad.

Ingredient Notes
Salmon: Choose similarly sized centre-cut fillets so they finish cooking together.

Lemon: Fresh juice and zest provide a brighter flavour than bottled juice.
Garlic: Mince it finely so it cooks quickly and distributes evenly.
Paprika: Adds colour and mild flavour without making the salmon spicy.
How to Make Lemon Garlic Butter Salmon
Step 1: Prepare the Oven
Preheat the oven to 400°F.
Line a rimmed baking sheet or shallow baking dish with parchment paper or aluminium foil.
Step 2: Prepare the Salmon
Pat the salmon fillets dry.
Arrange them skin-side down with space between each piece.
Season lightly with salt and black pepper.
Step 3: Make the Lemon Garlic Butter
Mix the melted butter, garlic, lemon juice, lemon zest, Italian seasoning and paprika in a small bowl.
Step 4: Coat the Salmon
Spoon or brush the butter mixture evenly over every fillet.
Ensure some garlic and zest remain on top of each piece.
Step 5: Bake
Bake at 400°F for approximately 10–14 minutes.
The precise time depends on the thickness of the fillets. The salmon should flake easily with a fork while remaining moist in the centre.
The USDA recommends cooking fish to an internal temperature of 145°F. Some cooks remove salmon slightly earlier and allow residual heat to finish cooking it; choose a temperature appropriate for your needs.
Step 6: Finish and Serve
Spoon the melted butter from the baking dish over the salmon.
Sprinkle with parsley and serve with lemon wedges.
Tips for Perfect Baked Salmon
Use Evenly Sized Fillets
Similar thickness produces more consistent cooking.
Pat the Salmon Dry
Removing surface moisture helps the butter mixture cling to the fish.
Do Not Overcook
Salmon continues cooking slightly after leaving the oven. Begin checking the thinnest fillet early.
Use Fresh Lemon
Fresh juice and zest provide the cleanest citrus flavour.
Keep the Garlic on Top
Garlic that falls onto an exposed dry baking sheet can burn.
How to Tell When Salmon Is Cooked
Look for the following signs:
- The surface appears opaque.
- The thickest part separates into flakes.
- The centre remains moist.
- White protein may appear lightly on the surface.
- A thermometer gives your desired safe internal temperature.
Large amounts of white albumin often indicate that the salmon cooked too quickly or for too long, although it remains safe to eat.
Recipe Variations
Honey Lemon Salmon
Add one tablespoon of honey to the butter mixture.
Parmesan Garlic Salmon
Sprinkle two tablespoons of finely grated parmesan over the fillets before baking.
Spicy Garlic Butter Salmon
Add crushed red pepper flakes or cayenne pepper.
Lemon Dill Salmon
Replace the Italian seasoning with dried dill and garnish with fresh dill.
Salmon With Asparagus
Arrange thin asparagus beside the fillets and coat it lightly with olive oil, salt and pepper.
What to Serve With Salmon
- Air fryer garlic parmesan potatoes.
- Roasted green beans.
- Garlic parmesan Brussels sprouts.
- Honey-glazed carrots.
- Mashed potatoes.
- Steamed rice.
- Roasted asparagus.
- Courgette fries.
- Green salad.
Storage and Reheating
Refrigerate cooked salmon in an airtight container for up to three days.
Reheat it gently in a covered 300°F oven until warm. High heat can dry the fish.
Cooked salmon can be frozen for up to two months, although its texture may become slightly firmer after thawing.
Frequently Asked Questions
Can I use frozen salmon?
Yes. Thaw it completely in the refrigerator and pat it dry before seasoning.
Should I remove the salmon skin?
No. Baking the salmon skin-side down helps protect the flesh. The skin can be removed easily after cooking if you do not want to eat it.
Can I use olive oil instead of butter?
Yes. The flavour will be lighter and less creamy.
How long does salmon take at 400°F?
Individual 6-ounce fillets generally need approximately 10–14 minutes, depending on thickness.
Can I prepare it ahead?
Prepare the butter mixture ahead, but add it to the salmon shortly before baking.
