How to Make Comfort in a Bowl
Step 1: Sauté the Aromatics
Start by melting the butter and olive oil in a large pot over medium heat. Once they’re shimmering, toss in the sliced leeks and chopped onion. Let them cook, stirring occasionally, until they turn soft and translucent—about 6 to 8 minutes. This gentle sweat brings out their natural sweetness, forming the soup’s flavorful base.
Step 2: Add the Garlic and Veggies
Sprinkle in the minced garlic and let it cook for another minute, just until fragrant. Next, stir in the diced celeriac, potato, fresh thyme, and a pinch of salt and pepper. This medley is what transforms the soup into Comfort in a Bowl, with each veggie lending its unique texture and taste.
Step 3: Simmer to Tender Perfection
Pour in the vegetable broth and crank up the heat to bring everything to a gentle boil. Once bubbling, lower the heat and let the pot simmer away for 25 to 30 minutes. Check the vegetables with a fork—they should be meltingly tender and ready for blending.
Step 4: Blend Until Creamy
Take the pot off the heat and grab an immersion blender (or carefully transfer the soup in batches to a blender). Whizz everything together until the soup is silky-smooth and creamy. This is where the magic happens, turning humble ingredients into pure Comfort in a Bowl.
Step 5: Finish with Cream and Season
Stir in the milk or cream, then taste and adjust the seasoning with more salt and pepper if needed. Keep the soup warm over low heat while you tackle the toasts—the final flourish for your Comfort in a Bowl experience.
Step 6: Make the Gruyère Toasts
Preheat your broiler and arrange the baguette slices on a baking sheet. Brush each slice lightly with olive oil, then sprinkle generously with Gruyère and a dash of fresh thyme. Broil for 2 to 3 minutes, watching closely, until the cheese is melted and bubbling with golden edges.
Step 7: Serve and Savor
Ladle the hot soup into bowls and top with a few Gruyère toasts—let them float like little rafts or serve them on the side for dunking. Add a sprig of fresh thyme if you’re feeling fancy, and dig in to your well-deserved Comfort in a Bowl.
How to Serve Comfort in a Bowl
Garnishes
A sprinkle of fresh thyme leaves or a swirl of cream can elevate each bowl, adding color and a fragrant final note. For extra texture, a crack of black pepper or a few microgreens on top can turn your Comfort in a Bowl into a feast for the eyes as well as the palate.
Side Dishes
While those Gruyère toasts are practically mandatory, you could also serve the soup with a crisp green salad, roasted root vegetables, or even a hunk of rustic, crusty bread. A glass of white wine or sparkling cider rounds out the meal, making your Comfort in a Bowl truly complete.
Creative Ways to Present
Try pouring the soup into small mugs for a cozy appetizer, or serve it in hollowed-out mini bread bowls for a playful, rustic touch. For a dinner party, float a Gruyère toast in each bowl and sprinkle with edible flowers or chives for show-stopping Comfort in a Bowl presentation.
Make Ahead and Storage
Storing Leftovers
Let any leftover soup cool completely before transferring it to an airtight container. It will keep in the refrigerator for up to four days, making it easy to enjoy Comfort in a Bowl all week long—just be sure to store the Gruyère toasts separately to keep them crisp.
Freezing
This soup freezes beautifully, but for the best texture, freeze it before stirring in the milk or cream. After thawing, simply reheat and add the dairy. Store in freezer-safe containers or bags for up to three months, so you can have Comfort in a Bowl ready at a moment’s notice.
Reheating
To reheat, warm the soup gently on the stovetop over medium-low heat, stirring frequently. If it’s too thick, add a splash of broth or milk. Toast the Gruyère slices in the oven or toaster oven until bubbly and crisp, then serve alongside your steaming bowl of comfort.
FAQs
Can I make this soup vegan?
Yes! Swap the butter for more olive oil, use a plant-based milk or cream, and either skip the Gruyère toasts or use your favorite vegan cheese. You’ll still get that signature Comfort in a Bowl flavor and texture.
What is celeriac, and can I substitute it?
Celeriac, also known as celery root, has a mild, nutty flavor and creamy texture when cooked. If you can’t find it, try substituting with parsnips or more potato, though the unique taste of Comfort in a Bowl will be slightly different.
Can I make the Gruyère toasts ahead of time?
You can prepare the toasts a few hours in advance and reheat them in the oven before serving. This keeps them crisp and melty, perfect for topping your Comfort in a Bowl.
Is this soup gluten-free?
The soup itself is gluten-free, so simply use a gluten-free baguette or omit the toasts if you’re looking for a gluten-free Comfort in a Bowl experience.
How do I make the soup even more flavorful?
For extra depth, consider roasting the celeriac cubes before adding them to the soup. You can also add a splash of white wine with the broth or finish with a drizzle of truffle oil for a restaurant-worthy Comfort in a Bowl.

Ingredients
Soup Ingredients
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 2 large leeks (white and light green parts only, cleaned and sliced)
- 1 medium onion (chopped)
- 2 garlic cloves (minced)
- 1 medium celeriac (about 1.5 pounds, peeled and diced)
- 1 large russet potato (peeled and diced)
- 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried)
- 4 cups vegetable broth
- 1 cup whole milk or cream
- Salt and pepper to taste
- Fresh thyme sprigs for garnish (optional)
Gruyère Toast Ingredients
- 1 small baguette (sliced)
- 1 cup grated Gruyère cheese
- 1 teaspoon fresh thyme leaves
- Olive oil for brushing
Instructions
- Sauté Aromatics: In a large pot, heat the butter and olive oil over medium heat. Add the sliced leeks and chopped onion, sautéing for 6–8 minutes until soft and translucent. This builds the flavor base for the soup.
- Add Garlic and Vegetables: Stir in the minced garlic and cook for another minute to release its aroma. Then add the diced celeriac, peeled potato, thyme, and a pinch of salt and pepper.
- Simmer Soup: Pour in the vegetable broth and bring the mixture to a boil. Reduce the heat to low and let it simmer gently for 25–30 minutes, or until the celeriac and potato are very tender. This slow cooking softens the vegetables and deepens the flavors.
- Blend Soup: Remove the pot from heat. Use an immersion blender to puree the soup until smooth and creamy; alternatively, blend in batches in a blender. Stir in the whole milk or cream and adjust seasoning with salt and pepper as needed. Keep the soup warm on low heat.
- Prepare Gruyère Toasts: Preheat your broiler. Arrange the baguette slices on a baking sheet, brush each slice lightly with olive oil, then sprinkle grated Gruyère cheese and fresh thyme leaves evenly on top.
- Broil Toasts: Place under the broiler for 2–3 minutes or until the cheese is melted, bubbly, and lightly browned. Watch carefully to avoid burning.
- Serve: Ladle the hot soup into bowls, garnish with fresh thyme sprigs if desired, and serve with Gruyère toasts either on the side or floating atop the soup. Enjoy immediately for best texture.
Notes
- This soup freezes well if you omit adding the milk or cream before freezing. Add these after thawing and reheating for best texture.
- For a deeper, nuttier flavor, try roasting the celeriac cubes in the oven before adding them to the soup.
- If Gruyère cheese is unavailable, Parmesan makes a good substitute for the toasts.
- The recipe is gluten-free if you skip the toasts or use gluten-free bread options.
