Boursin and Gruyere Spinach and Artichoke Gratin Dip

Arrange the oven rack in the middle position. Preheat the oven to 400 degrees F. In a large bowl, stir together the spinach, artichokes, wine, Boursin, cream cheese, and 1 cup of Gruyère. Season with salt and pepper, and mix until thoroughly combined. Spread the mixture in a baking or gratin dish large enough to hold everything. Top with the remaining cup of Gruyère. Bake for 15 minutes. Then, turn on the broiler, and broil just until the top is golden brown. To make the baguette chips (if using), turn the oven down to 350 degrees F. Arrange the baguette slices in an even layer on a baking sheet (you will need at least two baking sheets). Drizzle very lightly with olive oil, and toast for 10 to 12 minutes, until crisp and golden around the edges. Repeat with any remaining baguette slices.
