The Ultimate Baked Salmon Recipe - Over 1000 5-Star Reviews! · Natashas Kitchen
Natasha Kravchuk shows seasoning a salmon fillet with garlic herb butter and baking at 400°F until tender and flaky.
- Target //Cook at 400°F (204°C) for 12 mins.
- Doneness //Pull when internal temperature reaches 145°F (USDA safe minimum). Rest 3 mins before slicing.
- Golden Rule //Buy skin-on fillets even if you plan to remove the skin at the table. The skin acts as an insulating layer against the hot foil, keeping the underside from overcooking while the top surface climbs to 125°F.
- Family Tweak //Skip the cracked pepper and serve with a small ramekin of honey mustard or teriyaki glaze on the side for dipping.

Step by step
Tap a step to cross it offPreheat and Prep the Pan
Preheat the oven to 400°F (204°C) on the middle rack. Line a half sheet pan with aluminum foil for zero cleanup and to keep the skin from bonding to the pan.
WhyA fully preheated oven is non-negotiable. Cold ovens produce steamed, gray-banded salmon instead of a crisp-topped fillet.
Season the Fillets
Pat 4 (6-oz) skin-on salmon fillets bone-dry with paper towels. Rub each all over with olive oil (2 tbsp total), then season generously with kosher salt (1 tsp) and cracked black pepper (1/2 tsp).
WhyDry-surface salmon browns rather than steams. A 1-minute paper-towel blot pays off in visible crust.
Add Garlic, Lemon, and Butter
Scatter 3 minced garlic cloves across the tops. Arrange 1 thinly-sliced lemon over the fillets and set 2 tbsp cold butter in small pats on top so it melts down gradually as they cook.
WhyCold butter pats melt slowly and baste the salmon throughout the bake rather than scorching brown in the first 60 seconds.
Bake to Just Under Safe Temp
12 minPlace the pan on the center rack. Bake 10-12 minutes depending on thickness (rule of thumb: 4-6 minutes per half-inch). Pull when the thickest part reads 125°F on an instant-read thermometer.
WhyUSDA safe temp is 145°F, and carryover cooking pushes 125°F to 130-135°F during the 3-minute rest — hitting perfect medium without overshoot.
Rest and Serve
Let the fillets rest on the pan for 3 minutes so the juices redistribute. Serve with the pan-drippings and softened lemon slices spooned over the top.
WhySlide a thin metal spatula between the flesh and skin. The skin stays welded to the foil and the fillet lifts off cleanly with no scraping.
- Dad pro tip
- Buy skin-on fillets even if you plan to remove the skin at the table. The skin acts as an insulating layer against the hot foil, keeping the underside from overcooking while the top surface climbs to 125°F.
