Step 1

Preheat oven to 375°F. Combine Parmesan, breadcrumbs, garlic, salt, and 1/2 teaspoon pepper in a large bowl. Reserve 1/3 cup of the breadcrumb mixture; set aside.

Step 2

Add green beans, artichoke hearts, and olive oil to bowl with remaining breadcrumb mixture, and fold to combine well. Pour green bean mixture into a lightly greased 13- x 9-inch baking dish. Sprinkle reserved breadcrumb mixture evenly over casserole.

Step 3

Cover with aluminum foil, and bake until heated through, about 30 minutes. Uncover and bake until lightly golden and bubbly, about 10 minutes. Sprinkle with remaining 1/4 teaspoon pepper, and if desired, chopped parsley.
