Preheat Oven: Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.

Roll Out the Dough: Unroll the crescent roll or pizza dough onto the prepared baking sheet. If using crescent roll dough, press the perforations together to form a solid sheet of dough.

Cut and Shape the Dough: Cut the dough into triangles, each about 3-4 inches wide at the base. You will be forming a Christmas tree shape, so leave the triangles attached if possible, forming rows with the larger triangles at the base and smaller ones toward the top.

Fill the Dough: Spread the spinach dip evenly over half of each triangle. Sprinkle the shredded mozzarella cheese over the spinach dip.

Fold and Shape: Fold the other half of each dough triangle over the filling and press the edges to seal. Arrange the filled dough triangles in the shape of a Christmas tree on the baking sheet, with the pointy ends facing outward.

Brush with Garlic Butter: In a small bowl, mix the melted butter with garlic powder and Italian seasoning. Brush the garlic butter over the top of the dough.

Bake: Bake the spinach dip breadsticks in the preheated oven for 15-18 minutes, or until golden brown and cooked through.

Garnish and Serve: Once baked, sprinkle the grated Parmesan cheese and chopped fresh parsley over the top. Serve the Christmas tree spinach dip breadsticks with marinara sauce for dipping if desired.
