Preheat oven to 350°. Line a rimmed baking sheet with parchment paper.
Place baguette slices on prepared baking sheet, and brush lightly with melted butter.
Bake until light golden brown, approximately 5 minutes. Remove from pan, and let cool.
In a small bowl, stir together cream cheese, artichokes, lemon zest and juice, and thyme leaves until well combined. Divide cream cheese mixture among baquette slices, spreading to cover.
Garnish with lemon zest and thyme sprigs, if desired. Serve immediately.
