1Bring water to a boil in a large Dutch oven. Add orzo and garlic, and return to a boil; cook 10 minutes. Drain, rinse in cold water, and drain again. Remove garlic; peel and crush garlic. Set orzo aside.
2Combine garlic and whipping cream in a large bowl; beat with a wire whisk until blended. Add orzo, chicken broth, 1 cup minced parsley, 3/4 cup Parmesan cheese, and salt and pepper to taste; stir well.
3Place mixture in a greased 2-quart baking dish. Combine breadcrumbs, remaining 1/4 cup parsley, and remaining 1/4 cup Parmesan cheese; stir well. Sprinkle the crumb mixture over the orzo mixture. Dot with butter. Bake at 325° for 1 hour and 15 minutes or until golden brown.
