Ingredients You’ll Need

One of the things I love about this Roasted Celery and Potato Soup is how it relies on simple, everyday ingredients, yet every single one plays an essential role in crafting the perfect blend of flavors and textures. From the hearty Yukon gold potatoes to the fragrant garlic and fresh herbs, each component works in harmony to create a soup that’s rich, creamy, and full of soul.

• Celery (1 pound, trimmed and chopped): Roasting celery brings out a sweet and slightly smoky flavor that forms the heart of this soup.
• Yukon gold potatoes (1 pound, peeled and cubed): These potatoes give the soup its velvety texture and subtle buttery taste when blended smooth.
• Yellow onion (1, diced): Adds a gentle sweetness and depth when sautéed.
• Garlic (4 cloves, minced): Delivers a warm, aromatic undertone that enhances every spoonful.
• Olive oil (3 tablespoons): Used both for roasting and sautéing, it brings richness and helps those golden edges develop.
• Vegetable broth (4 cups): The base that melds all the roasted flavors together into liquid comfort.
• Dried thyme (1 teaspoon): Infuses a subtle herbal note that perfectly complements celery and potatoes.
• Salt and black pepper (to taste): Essential seasonings that bring the flavors into balance.
• Heavy cream (½ cup, optional): For those who love extra indulgence, this creamy addition makes the soup even more luscious.
• Chopped chives or parsley (for garnish): Adds a fresh, bright finishing touch to your bowl.

How to Make Roasted Celery and Potato Soup

Step 1: Roast the Vegetables

Start by heating your oven to 425°F (220°C). Spread the chopped celery and cubed potatoes on a baking sheet, then drizzle with 2 tablespoons of olive oil. Season generously with salt and pepper. Roast for about 25 to 30 minutes, giving them a good stir halfway through to ensure even caramelization. Roasting creates those beautiful golden-brown bits that bring intense flavor and sweetness to your soup.

Step 2: Sauté Aromatics

While your veggies roast, warm 1 tablespoon of olive oil in a large pot over medium heat. Add the diced onion and let it soften for around 5 minutes, releasing its natural sweetness. Stir in the minced garlic and dried thyme, cooking together for just another minute to let their fragrances bloom—this simple sauté is the flavor base that lifts the soup to a whole new level.

Step 3: Combine and Simmer

Once your celery and potatoes are roasted to golden perfection, add them straight to the pot with your softened aromatics. Pour in the vegetable broth, then bring the mixture to a boil. As soon as you see those bubbles, reduce the heat and let the soup simmer for 10 to 15 minutes, allowing all those flavors to meld beautifully.

Step 4: Blend to Creamy Perfection

For the signature smooth texture of Roasted Celery and Potato Soup, use an immersion blender right in the pot to blend until silky and creamy. If you don’t have one, just carefully transfer the soup in batches to a regular blender. Either way, keep blending until you reach that comforting velvety consistency that makes every spoonful divine.

Step 5: Finish and Season

Now, if you’re feeling indulgent, stir in the half cup of heavy cream to add richness that’s pure comfort in a bowl. Give your soup a final taste, and adjust salt and pepper to your liking. This final seasoning step brings all the flavors into perfect harmony, making that Roasted Celery and Potato Soup irresistibly delicious.

How to Serve Roasted Celery and Potato Soup

Garnishes

Simple garnishes are the cherry on top of your soup masterpiece. A sprinkle of chopped chives or parsley adds a beautiful pop of color and a subtle fresh flavor that beautifully contrasts the soup’s creamy earthiness. For a twist, a drizzle of extra virgin olive oil or a few crispy croutons can add an inviting texture that makes each bite exciting.

Side Dishes

Pair this soup with a crusty loaf of bread or a warm baguette, perfect for dipping and savoring the leftover broth. A crisp, lightly dressed green salad complements the soup’s richness, balancing your meal with bright, refreshing notes. For heartier occasions, serve alongside roasted chicken or grilled cheese sandwiches for a classic, comforting combo.

Make Ahead and Storage

Storing Leftovers

This soup keeps wonderfully in the fridge for up to 4 days. Store it in an airtight container to preserve its fresh roasted flavors, and you’ll have a quick, wholesome meal ready to heat and enjoy whenever you need a comforting bite during the week.

Freezing

Roasted Celery and Potato Soup freezes beautifully. Pour cooled soup into freezer-safe containers or bags, leaving some space for expansion. It will keep well for up to 3 months, making it a fantastic make-ahead option to stock your freezer with nourishing, ready-to-go meals.

Reheating

To reheat, gently warm the soup on the stove over medium heat, stirring occasionally until heated through. You may find it thickens in the fridge or after freezing; if so, just add a splash of broth or water to bring it back to the perfect creamy consistency before serving.

FAQs

Can I use a different type of potato for this soup?

Absolutely! While Yukon gold potatoes offer a naturally buttery texture, russet potatoes or red potatoes will also work, though the soup’s texture and flavor may vary slightly. Yukon golds tend to give that perfect creaminess without needing extra cream, but feel free to experiment based on what you have.

Is roasting the celery necessary?

Yes, roasting the celery is the secret ingredient that deepens the flavor and adds a subtle sweetness and smokiness you just can’t get from boiling or sautéing alone. It’s crucial for that rich, comforting taste that defines this Roasted Celery and Potato Soup.

Can I make this soup vegan?

Definitely! Simply skip the heavy cream or use a plant-based cream alternative, and make sure your vegetable broth is vegan-friendly. The soup will still be deliciously creamy thanks to the roasted potatoes and celery.

How thick should the soup be?

This soup should be smooth and creamy but not overly thick—think a comforting, spoonable texture that coats your spoon nicely without feeling heavy. You can always adjust the thickness by adding more broth or cream when blending.

What herbs work best besides thyme?

While thyme pairs beautifully here, you could also try fresh rosemary, sage, or even a small handful of tarragon for a different but equally satisfying herbal twist. Just add them during the sauté step to infuse that lovely aroma into the soup.
