Toss broccoli with 2 tablespoons melted butter, salt, and pepper on a sheet pan and roast at 425°F for 12 minutes.
Pat cod dry and season both sides with salt and pepper; set aside on a plate.
Heat 2 tablespoons butter in a large skillet over medium-high heat and sear cod for 4 minutes per side until opaque.
Remove cod to a plate and whisk remaining butter with fresh dill and lemon juice in the pan for 1 minute to make a quick sauce.
Spoon herb butter over cod and serve alongside roasted broccoli with extra lemon wedges.
