In a medium skillet, melt butter over medium-high heat. Add onion and celery; cook until vegetables are tender, about 5 minutes. Add garlic; cook until fragrant, about 1 minute.
Transfer vegetable mixture to the work bowl of a food processor, and pulse until finely chopped, about 1 minute, stopping to scrape sides of bowl. In a large bowl, stir together vegetable mixture, all bread crumbs, broth, salt, and pepper until well combined.
