If you need dinner fast but still want it to taste like you tried, Pan Seared Lemon Rosemary Salmon is the move. Crispy edges, buttery garlic-rosemary flavor, and a bright squeeze of lemon — all in one pan, in about 20 minutes.
And yes, you can totally make this with Costco frozen Atlantic salmon. I just thaw a couple fillets, pat them really dry, and cook like they were fresh.
If you’re on a quick seafood streak, try my Garlic Shrimp, Cod en Papillote, or Blackened Salmon next — because weeknight dinner should not be a whole production.

See recipe card for quantities.
Quick Tips Before You Start
- Pat the salmon very dry. Moisture kills a good sear
- Don’t move it once it hits the pan
- Use medium-high heat, not screaming hot
- Pull it early. Salmon keeps cooking off heat
How to Make Pan Seared Lemon Rosemary Salmon
- Season the salmon: Pat the salmon dry and season both sides with salt and pepper (and red pepper flakes if using).
- Pan-Sear: Heat a skillet (cast iron or stainless works best) over medium-high heat. Add the olive oil. Place salmon in the pan. If Skin-on, place skin-side down and press lightly for 10 seconds so it doesn’t curl. Cook 4–5 minutes without moving until golden and it releases easily.
Salmon Doneness (No Guessing)
- 125–130°F → tender, flaky, slightly glossy (recommended)
- 135–140°F → firmer but still juicy
No thermometer? It should flake easily but not look dry in the center.
Easy Sides That Pair Well
- Rice with roasted broccoli
- Garlic green beans
- Simple salad + crusty bread
- Creamy mashed sweet potatoes
Recipe Tips & Troubleshooting
- Salmon sticking? It’s not ready to flip yet. Give it another minute.
- Too dark too fast? Lower the heat slightly and keep going.
- Garlic browning too much? Add it with the butter at the end, not earlier.
- Reheating: Gently, low heat, or flake and use cold on salads.
Recipe FAQs
Both work. Skin-on gives extra protection from overcooking and adds crispiness; skinless cooks slightly faster.
The skin tightens as it cooks. Pressing lightly for the first 10 seconds prevents curling.
Oil for searing (higher smoke point), butter at the end for flavor.
Yes — use about 1 teaspoon dried. Add it with the butter so it blooms without burning.
About 1–1½ inches thick is ideal. Thinner fillets cook very fast, so watch closely.
