Trim the root end of the leek and cut off the dark green leaves (keep the pale green part of the leek).
Cut leek in half lengthwise and run under water to get rid of any dirt in the layers. Slice leeks.
Bring a small pan to medium heat and add 1 1/2 Tbsp butter.
Add sliced leeks and salt. Cover and cook ~ 4 -6 minutes (stirring occasionally), or until leeks are starting to get translucent but still retain some color. Reduce heat if butter or leeks starts to brown.
Remove leeks from heat and set aside.
Directions Salmon:
Salt and pepper salmon.
Add butter and parsley evenly to a large oven safe pan that will fit all four pieces of salmon. Place pan in oven (without salmon) for a couple minutes until you hear or see the butter is starting to sizzle.
Remove pan (and remember that this pan is HOT) and place salmon skin side up in the pan.
Bake uncovered 4-5 minutes or until the skin easily peels off.
Peel off skin, flip salmon and cook an additional 2-4 minutes or until salmon is done to your preference.
Top with buttery leeks and add salt to taste.
Notes
This pan and handle is HOT. When you take it out of the oven, put a dishtowel immediately around the handle so that you or anyone in your household does not grab it.
Wild salmon cooks faster than farmed salmon because it has less fat but is also generally thinner.
