Baked salmon with garlic butter is the 20 minute dinner that tastes like you spent an hour on it but you really just turned on the oven. ♡

This baked salmon with garlic butter slides a whole fillet into a hot oven slathered in fragrant lemon garlic butter so the fish stays buttery soft inside while the edges caramelize golden. Ready in 20 minutes, this easy salmon dinner is exactly what you pull out of the fridge on a busy Tuesday. Fans of my miso glazed salmon and one pan lemon herb salmon will love how simple this one is.
No marinating, no flipping, no worrying about overcooking. One sheet pan, one brush, one amazing dinner. Let’s make it together.

Ingredients
Baked Salmon with Garlic Butter
- 1.5 lbs salmon fillet, skin on or off
- 6 tbsp unsalted butter, softened
- 6 cloves garlic, finely minced
- 2 tsp fresh lemon zest
- 2 tbsp fresh lemon juice
- 1 tbsp fresh parsley, chopped
- 1 tsp fresh thyme leaves
- 1 tsp kosher salt
- 1/2 tsp black pepper
- 1/4 tsp red pepper flakes
- 1 tbsp olive oil
- lemon slices, for serving
Optional add ins
- capers scattered on top
- a drizzle of honey for sweet garlic butter
- fresh dill instead of thyme
- a pinch of smoked paprika for color
- a splash of white wine before baking

How to Make Baked Salmon with Garlic Butter
- Preheat. Set the oven to 400F and line a sheet pan with parchment. Let the salmon rest at room temperature for 15 minutes so it cooks evenly.
- Mix. In a small bowl mash the softened butter with the garlic, lemon zest, lemon juice, parsley, thyme, salt, pepper, and red pepper flakes into a smooth compound butter.
- Season. Pat the salmon dry and place it on the sheet pan. Drizzle with olive oil and pat the garlic butter evenly across the top.
- Bake. Roast for 12 to 15 minutes depending on thickness, until the salmon flakes easily with a fork and registers 125F at the thickest part.
- Broil. Switch the oven to broil for the final 2 minutes to blister the top and deepen the golden crust.
- Rest. Let the salmon rest for 3 minutes so the juices redistribute. Spoon the melted pan butter back over the top.
- Serve. Finish with fresh lemon slices and extra parsley and serve immediately.
Why This Recipe Works
Compound butter is a restaurant trick that pays off hard at home. Mashing softened butter with garlic, herbs, and citrus first lets the flavors marry and distribute evenly across the fish. If you tried to add raw garlic on top during baking, it would burn into bitterness. The butter acts as a buffer that gently infuses the flavor without scorching.
Pulling the salmon at 125F is the temperature sweet spot. Salmon protein begins to firm around 120F and loses juice rapidly past 135F. Landing right in the middle gives you that buttery medium that restaurants charge 30 dollars for.
The final two minute broil is a finishing move that transforms the top from pale to deeply golden. You get caramelization without overcooking the interior, since by then the butter is already melted into the flesh and the fish is nearly done.
Tips
- Storage. Keep in an airtight container in the fridge for up to 3 days. The fish firms up in the cold but keeps its flavor beautifully.
- Reheating. Reheat gently in a 300F oven for 8 minutes. Microwaving salmon releases a strong fishy smell and dries out the flesh.
- Meal prep. Flake leftover salmon into a grain bowl or salad all week.
- Mistake to avoid. Do not rinse the salmon before cooking. Rinsing spreads surface bacteria and washes away flavor. Just pat dry.
- Ingredient swap. Any salmon fillet works, wild sockeye cooks faster than Atlantic so check at 10 minutes.
- Freshness tip. Fresh salmon should smell clean and oceanic, never fishy. Wild salmon is more vibrant, farmed is richer in fat.
- Temperature check. A probe thermometer is the only way to know for sure. Visual doneness varies by thickness.
Variations
- Honey garlic salmon: whisk 1 tbsp honey into the butter for a sticky glaze
- Cajun garlic butter: add 1 tsp cajun seasoning to the compound butter
- Dill and lemon: swap thyme for dill and double the lemon zest
- Pesto topped: skip the herbs and spread 2 tbsp pesto on top before baking
- Parmesan crusted: sprinkle 1/4 cup grated parmesan over the butter before baking
- Brown butter: brown 3 tbsp of butter first, cool, and whisk into the compound butter
Common Mistakes to Avoid
- Cold salmon. Fish straight from the fridge cooks unevenly. Let it temper for 15 minutes first.
- Oven too hot. Over 425F the exterior overcooks before the interior catches up. 400F is the sweet spot.
- Skipping the broil. Without it the top stays pale and misses the golden caramelization.
- No thermometer. Eyeballing doneness usually leads to dry overcooked salmon. 125F is the magic number.
- Flipping the salmon. Flipping breaks up the flesh. Just bake, do not flip.
