  2. Wooden Spoon – Helps stir onions continuously for that golden sweetness.
  3. Chef’s Knife & Cutting Board – Essential for thinly slicing onions and preparing garlic.
  4. Oven-Safe Soup Bowls – These allow you to finish the soup in the oven with that cheesy crust.
  5. Baking Sheet – To toast baguette slices before layering them on top.
  6. Box Grater – For shredding Gruyere and Parmesan cheese fresh.
With these tools ready, you’ll be set up for soup-making success every single time.
