Essential Ingredient Guide

- Baguette slices: A day‑old baguette gives a sturdy base for melting the cheese.
- Nutritional yeast: Provides a cheesy umami note and a touch of nuttiness.
- Sherry (optional): Adds a subtle brightness; use a splash toward the end of cooking.
- Fresh thyme: Infuses the broth with a fragrant, earthy lift.

Pro Tips
Well, after you’ve baked the baguette, take a moment to glance at the steam rising—it's like a quiet reminder of home. The soup holds its warmth, but the crust should crackle as you dip. I’ve found that a pinch of sea salt right before serving brightens everything without overwhelming the delicate onion notes.
