# Easy Baked Salmon

Baked salmon is the easiest way to get a dinner-ready fish with almost no cleanup. The oven heats the fillets evenly, the garlic butter keeps them moist, and the whole thing takes about 25 minutes from start to table.

This recipe uses a hot 400°F (200°C) oven so the outside sets quickly and the middle stays tender. A squeeze of lemon at the end keeps it bright instead of heavy.

## Ingredients

- 4 salmon fillets (about 170 g each), skin on
- 2 tbsp olive oil
- 1/2 tsp kosher salt
- 1/4 tsp black pepper
- 1/2 tsp garlic powder
- 1/2 tsp smoked paprika
- 2 tbsp butter, melted
- 2 cloves garlic, minced
- 1 lemon, half sliced, half for juice
- 1 tbsp fresh parsley, chopped

## Method

1. Heat the oven to 400°F (200°C) with a rack in the middle. Line a rimmed baking sheet with parchment.
2. Pat the salmon dry with paper towels. Set the fillets skin side down on the sheet with a little space between them.
3. Rub each fillet with olive oil. Sprinkle with salt, pepper, garlic powder and smoked paprika.
4. Stir the melted butter with the minced garlic and spoon it over the fish. Lay a few lemon slices on top.
5. Bake for 12 to 14 minutes. The salmon is done when the thickest part reaches 145°F (63°C) and the flesh turns opaque and flakes easily with a fork.
6. Rest the fish for 3 minutes on the pan. Squeeze the other lemon half over it and scatter with parsley.
7. Serve with rice, roasted potatoes or a green salad.

## Why it works

- Patting the fish dry lets the surface season and brown lightly instead of steaming.
- Oil and butter coat the flesh so the top does not dry out in the dry heat of the oven.
- A 400°F (200°C) oven cooks a 2.5 cm thick fillet in about 12 minutes, before the proteins squeeze out too much moisture.
- Resting for a few minutes lets the last bit of heat finish the center gently.
- Lemon juice added after baking keeps its fresh aroma, which would fade in the oven.

## The science

- **Why salmon stays moist at 145°F.** Salmon muscle proteins start to tighten around 120°F (50°C) and squeeze out water as they firm up. Pulling the fish near 140 to 145°F (60 to 63°C) keeps most of that juice inside. The white film that appears is albumin, a harmless protein pushed to the surface.
- **Fat as a heat buffer.** Salmon is rich in fat, which slows heat travel and keeps the flesh silky. Brushing the top with oil and butter adds a protective layer so the surface does not dry out before the center is cooked.
- **Carryover heat.** The fillet keeps cooking after it leaves the oven because the hot outer layers pass heat inward. Removing it slightly early and resting it for a few minutes lets the center finish gently without overcooking the edges or drying out the surface.

## Tips

- Take the salmon out of the fridge 10 minutes before baking so it cooks more evenly.
- For thin tail pieces, fold the thin end under so it matches the thickness of the rest.
- Check at 12 minutes and then every minute, because thin fillets can finish early.

## Mistakes to avoid

- Baking at a low temperature for too long dries the fish out, so use 400°F (200°C) and watch the clock.
- Skipping the pat dry leaves the surface wet and pale, so blot it well with paper towels.
- Waiting for the fish to be fully firm in the oven leads to dry salmon, so pull it when a fork just flakes it and let it rest.

## Variations and swaps

- Brush with a mix of Dijon mustard and honey before baking for a sweet tangy crust.
- Top with thin tomato and red onion slices and a spoonful of pesto.
- Add a sprinkle of Cajun seasoning and serve with lime wedges.
- Swap the butter for extra olive oil to make it dairy free.
- Swap the smoked paprika for dried dill for a lighter, herby flavor.
- Swap salmon for arctic char or steelhead trout, which cook in the same time.

## Storage

Cool within 2 hours, then refrigerate in an airtight container for up to 3 days. Reheat gently at 275°F (135°C) until warmed through to 165°F (74°C), or eat it cold on salads.

## FAQ

**How long do you bake salmon at 400°F?**

Bake salmon fillets about 12 to 14 minutes at 400°F (200°C) for a fillet around 2.5 cm thick. Thicker pieces need a few more minutes, and thin ones need fewer. Check with a fork or a thermometer.

**What temperature is salmon done?**

Salmon is done at 145°F (63°C) in the thickest part, per USDA guidance. Many cooks pull it at 135 to 140°F (57 to 60°C) for a softer center and let carryover heat finish. The flesh should look opaque and flake easily.

**Should I bake salmon covered or uncovered?**

Bake it uncovered for the best texture. Covering with foil traps steam, which makes the fish softer and a bit watery. Use foil only to line the pan.

**Do I bake salmon skin side up or down?**

Skin side down. The skin protects the flesh from the pan and is easy to slide a spatula under once cooked.

**Can I bake salmon from frozen?**

Yes, but add about 5 to 8 minutes and rinse off any ice glaze first. For best results thaw it overnight in the fridge.
