    Tips & Tricks (5)

    • Spinach Moisture Magic 💦
      Squeeze frozen spinach thoroughly in a clean kitchen towel to remove excess moisture, preventing a watery casserole texture.
    • Flavor Layering Technique 🧅
      Sauté onions and garlic before adding ground beef to develop a deeper, more complex flavor foundation for the casserole.
    • Cheese Melt Perfection 🧀
      Reserve some mozzarella to sprinkle on top during the last 10 minutes of baking for a golden, crispy cheese crust.
    • Seasoning Balancing Act 🌶️
      Taste and adjust hot sauce and seasonings after mixing ingredients, as the cheese and cream of celery soup already contain salt.
    • Make-Ahead Magic ⏰
      Assemble the casserole up to 24 hours in advance and refrigerate, allowing flavors to meld and making dinner prep easier.
