Preheat the oven to 400 degrees F. Spray a baking sheet with nonstick cooking spray or line with parchment paper.
In a food processor, combine the crackers, basil, cheese, parsley and garlic salt and process to fine crumbs (the texture of breadcrumbs). Roll the artichoke hearts in the cracker crumb mixture and place on the prepared baking sheet.
Bake until the cracker crumbs are golden brown, about 30 minutes. Arrange the artichokes on a serving platter with toothpicks. Serve with marinara sauce for dipping, if desired.
