Making this delicious salmon in cast iron is as easy as the recipe list. It only takes a few steps to create a perfectly seared salmon a la plancha in no time at all.
Step 1: Make the Lemon Butter Mixture
In a small bowl, whisk your melted butter, fresh lemon juice, minced garlic, and chopped thyme together. Set aside.
Step 2: Pan Sear the Salmon
Heat your plancha griddle or cast iron skillet over medium heat until hot. Drizzle melted butter on the bottom of the cooking surface and place the salmon, skin side down, onto it. Pour the lemon butter over the salmon and sautee on medim-high heat for 10 to 13 minutes or until the salmon is flaky with a fork.
Step 3: Finish in the Oven
Place the salmon under the broiler for about a minute to finish the recipe by browning the edges of the garlic.
Step 4: Plate
Finally, garnish your salmon with lemon wedges and more fresh thyme.
Hint: A plancha griddle is preferred for this recipe, but if you don’t have one, a cast iron skillet does the trick.
There aren’t a lot of ingredients to this recipe, but if you find yourself out of any of them, I have some substitutions here that will work well.
- Bottle Lemon Juice – Freshly squeezed lemon juice is preferred, but bottle will work in a pinch.
- Pre-Minced Garlic – If you don’t have fresh garlic, you can use minced garlic out of a jar.
- Dried Thyme – Fresh herbs are always best, but dried thyme will work if that’s all you have.
