Test Kitchen Discoveries

• Cook the onions in the rendered bacon fat to further the smoky meat’s flavor.
• Use chicken broth to moisten the casserole as it bakes to prevent it from tasting too heavy.
• For the best flavor, track down good-quality imported Gruyère cheese. Nutty tasting and smooth melting, it’s the perfect choice here.
