All the love for garlic soup

Welcome, all garlic lovers! We've made this recipe for you. This roasted garlic soup (sometimes known as 40 clove garlic soup) is our favorite new addition to our soup collection.

And don't worry about having to clear your social calendar and choose between your friends and this soup. Instead of using raw or sauteed garlic, which both have a strong and pungent flavor that lasts for days, we use roasted garlic.

Roasted garlic is an entirely different and wonderful magical thing. 45 minutes in the oven turns a head of garlic (or in this case, 3 heads) into soft, creamy, sweet, and slightly nutty little cloves completely unlike their raw version. It blends into the soup to create warm and cozy spoonfuls of rich umami heaven.

The 5 easy steps to make garlic soup

If you happen to have a few heads of leftover roasted garlic on hand, then you'll be eating this soup in about 20 minutes. If not, set aside just under an hour.

  1. First things first, roast the garlic. Cut the tops off the head of garlic (so they're easy to squeeze out of the skin later), drizzle them with a little oil, and wrap them in an aluminum foil package. After 45 minutes in the oven they'll be soft, caramelized, and ready to be made into soup.
  2. Start the soup by sauteeing onion in butter just until it's translucent.
  3. Now add the wine, seasoning, chicken stock, and potatoes and bring the soup to a simmer.
  4. Once the garlic is soft (and it's cooled down enough that you don't burn your fingers) squeeze the cloves out of their skins and put them into the soup.
  5. Now all that you have to do is blend the soup and add a little cream and some parmesan cheese to take it to next level deliciousness.

The full recipe is in the recipe card below.

Gather your ingredients

  • Three heads of garlic – Yes, 3 whole heads!
  • Olive oil and butter – some for roasting the garlic and some for sauteeing the onion.
  • White wine – Dry white wine works best.
  • Italian seasoning – Try our homemade Italian seasoning!
  • Chicken stockBone broth will give your soup the best flavor. For a vegetarian soup, use vegetable broth.
  • Potatoes – We use russet potatoes, but peeled red or yellow potatoes will work, too. They give the soup a wonderful creamy texture.
  • Cream and parmesan – both of these add flavor, depth, and creaminess to your garlic soup.

Garlic soup FAQs

How garlicky is this soup?

If you've made it this far, we're assuming you're not afraid of a little garlic flavor. So for the garlic lover in you, this soup is definitely not too garlicky. Roasting garlic takes away its sharp, pungent flavor and leaves you with a garlic taste that is sweet and mellow instead.

Can I freeze this garlic soup for later?

Technically, yes you can. But soups with potatoes and cream are not the best option to freeze as potatoes can become grainy and dairy can separate. If you need to, put some in the freezer and cross your fingers. But don't make this soup with the intention of freezing it.

Talk to me about those croutons

Those mini soup croutons are our true loves. They're crispy little bites seasoned with herbs and garlic and the perfect tiny little size to fit several to a spoon without overtaking the soup. You won't regret making them!

Make it a meal

There's literally no reason in the world (that we can think of) that you wouldn't load up your bowl of garlic soup with mini croutons and call it dinner. It's a beautiful, simple, uncomplicated thing.

But if you want your bowl of soup to have some friends at the table, why not make a loaf of herb and cheese no yeast bread? Or set out a simple salad like our best kale salad or roasted winter salad.

Or turn it into a soup and sandwich deal with our bacon sandwich, sriracha grilled cheese, or even some warm bruschetta.

Garlic Soup Toppings

Instructions 

  • Preheat your oven to 400 degrees Fahrenheit. Cut the tips off the heads of garlic and place them cut side up in the center of a piece of aluminum foil (see notes). Drizzle the tops with olive oil then close the foil around them to create 3 little packages. Place the garlic in a small baking dish and roast for 45 minutes, or until it is soft. Remove it from the oven and carefully open the packages so the garlic can cool.

  • While the garlic is roasting, begin the soup. Melt the butter in a medium-sized soup pot over medium-high heat. Add the onion, salt, and pepper and saute until the onion is translucent – about 3 minutes.

Notes

If cooking with aluminum foil makes you uncomfortable, line the garlic packages with parchment paper to create a barrier between the garlic and the foil – it's what we do. 
If you use a regular blender to blend the soup, let the soup cool for a few minutes first. Then work in batches, only fill the blender half full each time, and hold the lid down when you blend the soup. Hot liquids expand when they're blended and have been known to pop the lid off of blenders.
