Ingredients You’ll Need
The magic of the Celeriac Leek Soup with Thyme Gruyère Toasts (Comfort in a Bowl) Recipe lies in its simplicity. Each ingredient plays a crucial role, from the tender leeks that give sweetness and depth, to the creamy celeriac and potato that make the soup so silky and rich. The Gruyère cheese isn’t just cheese; it’s the golden, bubbling finish that brings the entire dish together with its nutty, savory notes.
- 2 tablespoons unsalted butter: Adds a luscious, creamy base for sautéing the vegetables without overpowering their flavors.
- 1 tablespoon olive oil: Balances the butter and helps gently cook the leeks and onions to softness.
- 2 large leeks (white and light green parts only, sliced and rinsed): Bring a mild onion sweetness that is essential for this soup’s subtle flavor profile.
- 1 medium onion (chopped): Adds a savory backbone to complement the leeks and elevate the soup’s aroma.
- 2 cloves garlic (minced): A touch of fragrant warmth that blends beautifully with thyme and vegetables.
- 1 1/2 pounds celeriac (peeled and diced): The star ingredient with a delicate, celery-like earthiness that gives the soup its character.
- 1 medium potato (peeled and diced): Creates the perfect creamy texture when pureed, making the soup luxurious and filling.
- 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried): Herbs that add fragrant earthiness and enhance the overall flavor without overshadowing the vegetables.
- 5 cups low-sodium vegetable or chicken broth: Provides a flavorful foundation, allowing the vegetables to shine while keeping the soup smooth.
- 1/2 cup heavy cream: Swirled in at the end for indulgent creaminess that makes every spoonful silky and rich.
- Salt and black pepper to taste: Essential seasonings to bring out the flavors and balance the soup perfectly.
- 4 slices crusty bread: The ideal base to be topped with cheese and toasted to golden perfection.
- 1 cup shredded Gruyère cheese: Melts beautifully into toasty pockets of goopy, nutty goodness that complement the soup’s gentle flavors.
- 1/2 teaspoon thyme (for garnish): A sprinkle on top for aroma and a pretty visual touch.
How to Make Celeriac Leek Soup with Thyme Gruyère Toasts (Comfort in a Bowl) Recipe
Step 1: Sauté Aromatics
Begin by gently heating the butter and olive oil in a large pot over medium heat. Add the sliced leeks and chopped onion, taking care to keep the heat moderate so they soften without browning. This step releases their natural sweetness and forms the fragrant base of the soup; it should take about 5 to 7 minutes. Once they’re translucent and tender, stir in the minced garlic, letting its aroma bloom for just a minute before moving on.
Step 2: Add Vegetables and Herbs
Next, toss in the diced celeriac, potato, and thyme leaves. Stir everything well, allowing the herbs to infuse the vegetables for roughly two minutes while the mixture warms. This brief cooking wakes up the deeper flavors lurking in the root veggies and expertly integrates the herbal notes into the soup’s foundation.
Step 3: Simmer the Soup
Pour in your chosen broth, whether vegetable or chicken, bringing the mixture to a gentle boil. Right after, lower the heat so the soup simmers patiently for 25 to 30 minutes. During this time, the vegetables soften until they are tender enough to blend seamlessly, creating the soup’s creamy texture and inviting aroma.
Step 4: Blend to Creamy Perfection
Once the vegetables are meltingly soft, it’s time to puree the soup. Using an immersion blender right in the pot makes quick work of this, but if you prefer or don’t have one, carefully transfer portions to a countertop blender in batches. The result is a smooth, velvety soup that practically melts on the tongue.
Step 5: Finish with Cream and Seasoning
Stir in the heavy cream generously, which softens the flavors and adds a luxurious mouthfeel. Now is also the moment to season with salt and freshly cracked black pepper, adjusting until it feels just right. The soup should taste rich but balanced, with the warmth of thyme gently present under the soft flavors of celeriac and leek.
Step 6: Make the Thyme Gruyère Toasts
Set your oven broiler to high and arrange the crusty bread slices on a baking sheet. Generously top each slice with shredded Gruyère and sprinkle with thyme for extra fragrance. Broil these for 2 to 3 minutes, watching closely until the cheese is bubbling, golden, and irresistible. Serve these toasts alongside or resting on top of the steaming soup for that delightful combination of creamy and crunchy textures.
How to Serve Celeriac Leek Soup with Thyme Gruyère Toasts (Comfort in a Bowl) Recipe
Garnishes
While the soup shines on its own, adding a scattering of fresh thyme leaves or a light drizzle of extra cream on top can elevate its appearance and flavor. A tiny pinch of black pepper cracked over the surface just before serving also adds a subtle kick that wakes up the palate. These simple garnishes make the dish feel special, as if it was made just for you.
Side Dishes
This soup pairs beautifully with vibrant green salads dressed in lemon vinaigrette or a rustic roasted vegetable medley for a rounded meal. You might also serve it with pickled onions or a crisp apple slaw to add a refreshing contrast that balances the rich creaminess in the soup.
Creative Ways to Present
Imagine ladling this smooth, comforting soup into little crocks or mugs and topping each with one of those golden, cheesy thyme Gruyère toasts broken into croutons scattered on top. For a dinner party, serve the toasts elegantly on small skewers resting on the soup bowl’s rim for a playful twist. You could even swirl in a little pesto on the surface for an unexpected floral pop of color and flavor.
Make Ahead and Storage
Storing Leftovers
If you find yourself with leftovers of the Celeriac Leek Soup with Thyme Gruyère Toasts (Comfort in a Bowl) Recipe, simply cool the soup to room temperature and store it in an airtight container in the refrigerator. It will keep beautifully for up to 3 days, preserving that creamy texture and delicious flavor.
Freezing
This soup freezes wonderfully, though it’s best to hold off adding the cream until after reheating to prevent any separation. Transfer the cooled soup to freezer-safe containers or heavy-duty bags, and it will last up to 3 months. Thaw overnight in the fridge and warm gently on the stove.
Reheating
When ready to enjoy again, reheat the thawed or refrigerated soup over low to medium heat, stirring frequently to keep the texture silky. Once heated through, stir in the cream and season again if needed. Toast fresh bread, top with Gruyère and thyme, and broil just like before for that iconic ending touch.
FAQs
Can I use dried thyme instead of fresh thyme?
Absolutely! You can substitute 1 teaspoon of fresh thyme with 1/2 teaspoon of dried thyme, which still imparts a lovely aromatic flavor. Just add it a bit earlier in cooking to allow the dried herbs time to soften and release their essence.
Is celeriac hard to find or substitute?
Celeriac can sometimes be elusive depending on your location, but don’t worry—you can substitute it with parsnips or turnips. These alternatives will provide a similar earthy sweetness and texture, keeping the soul of the soup intact.
Can I make this recipe vegan?
Yes! Use plant-based butter and cream alternatives, and swap the Gruyère for a vegan cheese option that melts well. Vegetable broth should be your base to keep the flavors vibrant and comforting.
What bread works best for the thyme Gruyère toasts?
A crusty, sturdy bread like a baguette or sourdough works beautifully because it holds up against the melting cheese without becoming soggy. The chewy crust adds delightful texture against the smooth soup.
How do I avoid the soup becoming too thick after blending?
If your soup becomes too thick after pureeing, simply stir in a splash of extra broth or water until it reaches your preferred consistency. The goal is a velvety, spoonable soup that isn’t too dense or heavy.

Ingredients
Soup
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 2 large leeks (white and light green parts only, sliced and rinsed)
- 1 medium onion (chopped)
- 2 cloves garlic (minced)
- 1 1/2 pounds celeriac (peeled and diced)
- 1 medium potato (peeled and diced)
- 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried)
- 5 cups low-sodium vegetable or chicken broth
- 1/2 cup heavy cream
- Salt and black pepper to taste
Gruyère Toasts
- 4 slices crusty bread
- 1 cup shredded Gruyère cheese
- 1/2 teaspoon thyme (for garnish)
Instructions
- Sauté Aromatics: In a large pot, heat the unsalted butter and olive oil over medium heat. Add the sliced leeks and chopped onion, and cook for 5 to 7 minutes until the vegetables are soft and translucent but not browned. This step builds the flavor base for the soup.
- Add Vegetables and Herbs: Stir in the minced garlic, diced celeriac, diced potato, and fresh thyme leaves. Cook everything together for another 2 minutes to release the herbs’ aroma and slightly soften the root vegetables.
- Simmer Soup: Pour in the low-sodium vegetable or chicken broth and bring the mixture to a boil. Once boiling, reduce the heat to a simmer, cover, and cook for 25 to 30 minutes until the celeriac and potato are very tender and easily pierced with a fork.
- Puree the Soup: Use an immersion blender directly in the pot to puree the soup until completely smooth. Alternatively, carefully transfer the soup in batches to a blender and blend until creamy.
- Finish Soup: Stir in the heavy cream until fully incorporated. Season the soup with salt and black pepper to your taste. Keep the soup warm on low heat while preparing the toasts.
- Prepare Gruyère Toasts: Preheat the oven’s broiler. Arrange the crusty bread slices on a baking sheet. Evenly sprinkle shredded Gruyère cheese on top of each slice and add a pinch of thyme for garnish.
- Broil Toasts: Place the baking sheet under the broiler for 2 to 3 minutes, watching carefully until the cheese melts, bubbles, and turns lightly golden.
- Serve: Ladle the hot celeriac leek soup into bowls and serve immediately with the thyme Gruyère toasts on the side or placed on top for a delightful combination of creamy soup and cheesy crunch.
Notes
- You can substitute celery root with parsnips or turnips for a different but complementary flavor.
- For a lighter soup, use whole milk instead of heavy cream to reduce richness while maintaining a creamy texture.
- This soup freezes well if you omit the cream during storage; add the cream after reheating to preserve the best texture and flavor.
