Frequently Asked Questions

→ How do I make this soup thicker?
Start with 3 cups of broth instead of 4 for a thicker consistency. You can always thin it out later if needed.
→ Can I make this creamier?
Replace 1 cup of broth with milk, or use 1/2 cup of half and half or heavy cream for extra richness.
→ How do I know when the garlic is done roasting?
The garlic should be golden and soft enough to easily squeeze out of the skins after roasting for 30-35 minutes.
→ Can I use frozen cauliflower?
Fresh cauliflower works best for roasting as it caramelizes better. Frozen may result in a less rich flavor.
→ What cheese works best?
Sharp cheddar gives the best flavor, but you can use medium cheddar or a mix of cheeses like gruyere and cheddar.
