FAQs

Is this soup very garlicky?

Despite using 3 heads of garlic, the flavor is mellow and sweet from roasting, not sharp or overpowering.

Can I skip the wine?

Yes, replace it with additional chicken or vegetable stock.

What potatoes work best?

Russet potatoes are ideal for creaminess, but red or Yukon gold also work well.

Can I make it vegetarian?

Yes, use vegetable stock instead of chicken stock and ensure the cheese is vegetarian-friendly.

How can I thicken the soup more?

Blend longer, or add more potatoes. You can also stir in a bit of cornstarch slurry if needed.

Can I use pre-roasted garlic?

Absolutely, if you have roasted garlic ready, just skip the roasting step and add it directly to the soup.

What blender should I use?

An immersion blender is easiest. For a traditional blender, blend in small batches and allow soup to cool slightly first.

Is it freezer-friendly?

Yes, but cream soups can sometimes separate slightly. Stir well when reheating.

How do I make croutons?

Toss cubed bread with olive oil, garlic powder, and herbs. Bake at 375°F for 10–12 minutes until crisp.

What herbs go well with this soup?

Fresh parsley, thyme, or even a touch of rosemary add great flavor to this dish.
