Preheat the oven to 375°F. Grease a baking dish.
In a large bowl combine the Italian breadcrumbs, freshly grated Parmesan, minced garlic, salt, and black pepper. Mix until evenly combined. Reserve about 1/3 cup of the breadcrumb mixture and set aside for the topping.
Add the chopped artichoke hearts, drained green beans, olive oil, and fresh lemon juice to the bowl. Fold gently until the green beans and artichokes are evenly coated in the Parmesan breadcrumb mixture.
Pour into the prepared baking dish and spread into an even layer. Sprinkle the reserved breadcrumb mixture evenly over the top. Drizzle lightly with olive oil.
Cover tightly with foil and bake at 375°F until heated through, about 20 to 25 minutes. Remove the foil and continue baking uncovered for another 10 to 15 minutes until the top is golden brown and crispy.
Serve warm.
