Creamy Roasted Garlic Soup with Toasted Sourdough
Ingredients
Equipment
Method
- Preheat oven to 400°F (200°C). Slice off the top 1/4 inch from each garlic head, exposing the cloves.
- Place garlic heads on a baking sheet. Drizzle with 2 tbsp olive oil, sprinkle with 1/4 tsp salt and 1/8 tsp black pepper. Wrap loosely in aluminum foil.
- Roast for 35-45 minutes, or until cloves are very soft and golden brown. Let cool slightly, then squeeze the softened garlic cloves into a small bowl. Mash gently with a fork. Set aside.
- In a Dutch oven or large heavy-bottomed pot, melt 2 tbsp unsalted butter over medium heat.
- Add chopped yellow onion and celery. Cook for 5-7 minutes, stirring occasionally, until softened and translucent.
- Stir in the diced potato, dried thyme, 1/2 tsp salt, and 1/4 tsp black pepper. Cook for another 2 minutes.
- Add the mashed roasted garlic to the pot. Pour in 6 cups vegetable or chicken broth. Bring to a simmer, then reduce heat to low, cover, and cook for 15-20 minutes, or until the potatoes are very tender.
- Remove the pot from heat. Using an immersion blender, carefully blend the soup until completely smooth and creamy. Alternatively, transfer the soup in batches to a stand blender and blend until smooth (be cautious with hot liquids, venting the lid).
- Return the blended soup to the pot over low heat. Stir in the 1/2 cup heavy cream and 1/4 cup fresh parsley. Heat through gently for 2-3 minutes, ensuring it doesn’t boil. Taste and adjust seasoning if necessary.
- While the soup is simmering or blending, prepare the sourdough. Brush both sides of the thick-cut sourdough slices with 1 tbsp olive oil.
- Air Fryer Method: Place sourdough slices in a single layer in the air fryer basket. Air fry at 375°F (190°C) for 4-6 minutes, flipping halfway through, until golden brown and crispy.
- Oven Method: Place sourdough on a baking sheet and bake in the preheated oven (from garlic roasting, if still on) at 400°F (200°C) for 5-8 minutes, flipping halfway, until golden and crispy.
- Toaster Method: Toast in a regular toaster until golden, then lightly brush with olive oil if desired.
- Ladle the creamy roasted garlic soup into bowls. Garnish with a sprinkle of fresh parsley and a drizzle of olive oil, if desired.
- Serve immediately with the warm, crispy toasted sourdough bread on the side for dipping.
Notes
Leftover soup can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat gently on the stovetop, adding a splash of broth or cream if it’s too thick.
To make this soup vegan, substitute butter with olive oil or a plant-based butter alternative, and use a plant-based cream (like cashew cream or full-fat coconut milk) instead of heavy cream. Ensure to use vegetable broth.
Pro Tips for Making This Creamy Roasted Garlic Soup with Toasted Sourdough
The Art of Roasting Garlic
When it comes to the garlic, patience is truly a virtue, my dears. Don’t rush the roasting process! Allowing the garlic to slowly roast in olive oil until it’s beautifully caramelized and soft ensures that sweet, nutty flavor without any harshness. This is the heart of our Creamy Roasted Garlic Soup with Toasted Sourdough, so take your time and let those cloves become perfectly tender.
My Secret Trick: I always wrap my garlic heads tightly in foil after drizzling them with olive oil and a sprinkle of salt. This creates a little steamy environment that helps the cloves become incredibly soft and easy to squeeze out, ensuring no precious garlic goodness is left behind!
Achieving the Perfect Creamy Texture
For that silky-smooth texture, make sure your potatoes are fork-tender before blending. A good immersion blender or a careful batch blend in a regular blender will make quick work of it. If you prefer a slightly chunkier soup, you can reserve a few spoonfuls of the cooked vegetables before blending and stir them back in at the end.
Toasting Sourdough to Perfection
The toasted sourdough is more than just a garnish; it’s an integral part of the experience. I like to brush my sourdough slices with a little extra virgin olive oil and a pinch of salt before toasting them until golden and crisp. This ensures each bite of your Creamy Roasted Garlic Soup with Toasted Sourdough has that delightful textural contrast.
Fun Variations for Creamy Roasted Garlic Soup with Toasted Sourdough
One of the joys of cooking at home is making a recipe truly your own, and this Creamy Roasted Garlic Soup with Toasted Sourdough is wonderfully adaptable! Here are a few ideas to spark your creativity:
Herbaceous Twists
While dried thyme is lovely, feel free to play with other fresh herbs. A sprig of fresh rosemary roasted with the garlic can add a wonderfully earthy note, or a sprinkle of fresh chives or dill over the finished soup brightens everything up. My friend, Sarah, always adds a touch of sage to hers for a really comforting, autumnal feel.
A Touch of Spice
If you like a little kick, consider adding a pinch of red pepper flakes when sautéing the onions and celery. It won’t overpower the delicate garlic flavor but will add a subtle warmth that some find quite delightful. Just a whisper of heat can elevate this creamy roasted garlic soup into something truly unexpected.
Cheesy Indulgence
For an extra layer of decadence, stir in a handful of freshly grated Parmesan cheese into the soup just before serving. The cheese will melt beautifully, adding a savory, umami depth. I’ve even known some folks who sprinkle a little sharp cheddar on their toasted sourdough before serving!

What to Serve With Creamy Roasted Garlic Soup with Toasted Sourdough
This Creamy Roasted Garlic Soup with Toasted Sourdough is quite satisfying on its own, but sometimes a little something extra just makes the meal feel complete! Here are a few ways I love to round out this cozy experience:
- A Simple Green Salad: A crisp, light green salad with a bright vinaigrette provides a refreshing counterpoint to the richness of the soup. It’s what my mom always serves, and it just feels right.
- Crusty Bread (Beyond Sourdough!): While toasted sourdough is called for, any rustic, crusty bread is wonderful for dipping and soaking up every last drop of the creamy goodness.
- Grilled Cheese Sandwiches: For a truly comforting and nostalgic meal, a classic grilled cheese sandwich makes an excellent companion. The salty, savory cheese pairs perfectly with the mellow garlic.
- Roasted Vegetables: A side of simply roasted seasonal vegetables, like asparagus or broccoli, adds a lovely bit of freshness and nutrients to the plate.
