Preheat your oven to 400 degrees. Line a baking sheet with parchment paper.
Mix together the lemon juice, butter, salt, paprika, and lemon pepper.
Place cod in the middle of the parchment paper. Surround with the chopped asparagus and broccoli. Pour the butter and lemon juice mixture over the top. Top with chopped parsley.
Bake for 13 to 15 minutes or until the cod is no longer translucent, be cautious not to bake too long as the fish will dry out.
