Cast Iron Skillet Salmon is one of my favorite, simplest recipes. With just a handful of ingredients and a hot pan, a basic salmon fillet turns into something special. A squeeze of lemon, a touch of garlic salt, and a pat of butter bring balanced brightness and richness to the fish, while a screaming-hot cast iron skillet creates a crisp, golden exterior.

Why You’ll Love Cast Iron Skillet Salmon
There are many ways to cook salmon, but searing it in a hot cast iron skillet delivers dependable results: a golden-browned exterior, crisped skin, and a tender, pink interior. The intense, even heat of cast iron helps render fat and develop flavor quickly, making this technique ideal for both wild-caught and farmed salmon.
The method is fast and low-effort, which makes it perfect for weeknight dinners. It pairs well with simple sides like sautéed green beans, roasted potatoes, or a bright salad. Leftover salmon also works great flaked into salads or bowls the next day.
Tender Salmon Ingredients Round-Up
A good result starts with good ingredients. This recipe uses items you likely already have on hand, plus fresh salmon.
- Salmon – Skin-on fillets give you crispy skin and moist flesh. The classic seasoning here is lemon, garlic salt, parsley, and butter.
How to Make Cast Iron Skillet Salmon
Begin by lighting charcoal and allowing the coals to become hot and ashy. Spread the coals evenly and preheat a cast iron skillet over the grill for about 10 minutes — a properly hot pan is essential for a good sear.
Pro-Tip: What’s the best Charcoal for cooking salmon in a cast iron skillet?
Hardwood lump charcoal provides quick, high heat and clean burn, which is excellent for searing salmon without excessive smoke. If you prefer longer, more consistent heat, hardwood briquets offer a steadier burn while still adding a subtle wood character.
While the pan heats, pat the salmon dry to help the skin crisp. Season the flesh side with garlic salt and a squeeze of lemon, then let it rest at room temperature for a few minutes to take on the flavors.
When the skillet is smoking hot, add the butter and let it melt. Place the salmon skin-side down and sear undisturbed for roughly 6–8 minutes, depending on thickness. Use a fish spatula to flip the fillet to the flesh side and cook 2–3 minutes more. Return it to skin-side down, squeeze the remaining lemon over the top, sprinkle with chopped parsley, and serve immediately.
What to Serve with Cast Iron Skillet Salmon
This salmon works with many sides. Keep it light with a herb salad or roasted vegetables, or go heartier with roasted potatoes or grilled asparagus. A simple pan sauce or extra lemon wedges finish the plate nicely.
Leftovers and Reheating Salmon
Store leftovers in an airtight container in the refrigerator for up to two days. Reheat gently on the grill over indirect heat at a moderate temperature until warmed through, or give it a quick sear for a couple of minutes to revive the crust. Leftover salmon is excellent flaked into salads or served over rice.
Cast Iron care & more Recipes
Always dry cast iron thoroughly after washing to prevent rust — heat it briefly and coat it with a thin layer of oil while warm. Regular seasoning maintains its non-stick surface and longevity.
