Pat the salmon fillets dry with a paper towel.
Season both sides of the fillets with salt and pepper.
Heat olive oil in a skillet over medium-high heat.
Once hot, place the salmon skin-side down in the skillet.
Sear the salmon for about 4-5 minutes without moving it.
Carefully flip the fillets using a spatula.
Add butter to the skillet and baste the salmon for 2-3 minutes.
Cook until the salmon is opaque and flakes easily.
Remove from heat and squeeze fresh lemon juice over the top.
Garnish with dill and serve immediately.
