Ingredients for apple celery soup
Herbal depth meets subtle apple sweetness in this velvety soup's core ingredients.
| Ingredient | Amount | Notes |
|---|---|---|
| Granny Smith Apples 🍎 | 2 medium | Peeled, cored, diced small |
| Celery Stalks 🧅 | 4 whole | Trimmed, chopped into 1-inch pieces |
| Yellow Onion 🧅 | 1 medium | Diced, about 1 cup |
| Fresh Thyme Sprigs 🌿 | 2 tbsp | Leaves only, finely chopped |
| Bay Leaves 🌿 | 2 whole | Removed after simmering |
| Apple Cider Vinegar 🍋 | 1 tbsp | For brightness and balance |
| Vegetable Broth 💧 | 6 cups | Low-sodium preferred |
| Unsalted Butter 🧈 | 2 tbsp | For richness (vegan: use olive oil) |
| All-Purpose Flour 🌾 | 1 tbsp | For thickening slurry |
| Crème Fraîche 🧀 | ¼ cup | For serving (vegan: coconut yogurt) |
| Sea Salt 🧂 | 1 tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly cracked |

The apples are non-negotiable—Granny Smith delivers the perfect tartness to balance celery’s earthiness. Local farmers markets often have them at peak season, but any crisp variety works. For maximum flavor, peel and dice them small so they blend seamlessly into the broth. Celery should be bright green with crisp stalks—avoid wilted or yellowing pieces. The thyme and bay leaves are where the magic happens: fresh thyme from the grocery store’s herb section and dried bay leaves from a trusted brand like McCormick ensure that herbal depth that makes this soup sing.
No Granny Smith apples? Fuji or Honeycrisp work beautifully—they’re sweeter but still hold up well. Short on celery? Substitute with leeks or fennel for a similar texture, though the flavor profile shifts slightly. The butter can be swapped for olive oil in a vegan version, though it’ll have a different mouthfeel. For the flour slurry, arrowroot powder works too if you’re avoiding gluten. The apple cider vinegar is crucial—Bragg is a reliable brand, but any organic variety will do. If you’re making this ahead, skip the vinegar until reheating to preserve its bright flavor.
This soup tastes even better the next day as flavors meld—store leftovers in an airtight container for up to 5 days. For freezing, portion into 2-cup servings and thaw overnight in the fridge. The crème fraîche should be added fresh when serving, as it doesn’t reheat well. If you’re prepping for a crowd, double the broth and ingredients—this scales beautifully. The crusty bread pairs perfectly, so grab a baguette from the bakery section or toast your own sourdough for extra texture.

Step-by-step instructions for apple celery soup
Transform simple ingredients into a velvety soup where apple sweetness and celery's herbal notes harmonize perfectly.
Sauté the Vegetable Base
Heat the 2 tablespoons unsalted butter in a large pot over medium heat until it melts and begins to foam. Add the 1 medium yellow onion and 4 whole celery stalks (chopped into 1-inch pieces), stirring occasionally for 5-6 minutes until the onion becomes translucent and the celery softens slightly. Here's the thing—don't rush this step. The vegetables need time to release their natural sugars and develop flavor.
Add the 2 tablespoons fresh thyme sprigs (leaves only) and 2 whole bay leaves, stirring for another 30 seconds to infuse the aromatics. The thyme should release its piney fragrance while the bay leaves add subtle earthiness. This aromatic foundation is what makes the soup so complex. Keep the heat at medium—too high and you'll burn the thyme before it releases its oils.
Cook the Apples and Add Vinegar
Stir in the 2 medium Granny Smith apples (peeled, cored, and diced small) and cook for 3-4 minutes until they begin to soften slightly but don't break down completely. The slight resistance when you press them with a spoon indicates they're ready. This step is crucial—overcooking the apples will turn the soup mushy.
Pour in the 1 tablespoon apple cider vinegar and stir well. The vinegar brightens the flavors and balances the natural sweetness of the apples. Let the mixture simmer for 2 minutes until the vinegar is fully incorporated and the aroma becomes more pronounced. You'll notice the soup begins to take on a subtle golden hue from the caramelizing vegetables.
Build the Soup with Broth and Thicken
Pour in the 6 cups vegetable broth and bring the mixture to a gentle boil. Once boiling, reduce the heat to low and let it simmer uncovered for 15-20 minutes until the vegetables are completely tender and the apples have broken down into the broth. You'll know it's ready when a spoon slides through the mixture with minimal resistance.
Remove the 2 whole bay leaves—they've done their job and can be discarded. In a small bowl, whisk together the 1 tablespoon all-purpose flour and 1 teaspoon sea salt to create a slurry. Slowly pour this mixture into the pot while stirring constantly. The flour will help thicken the soup slightly, giving it that velvety texture we're after.
Season and Finish
Simmer the soup for an additional 5 minutes to allow the flour to fully incorporate and thicken the broth. Taste and adjust the seasoning with ½ teaspoon black pepper and more salt if needed. The soup should be well-balanced—slightly sweet from the apples, herbal from the celery and thyme, with a touch of tang from the vinegar.
For a richer finish, stir in the 2 tablespoons unsalted butter (if not already added) until it melts completely. This step adds a luxurious mouthfeel. Ladle the soup into bowls and serve immediately with a dollop of ¼ cup crème fraîche on top. The contrast between the warm soup and cool crème fraîche elevates the dish to restaurant quality.
Serve with Crusty Bread
Offer the 1 loaf crusty bread on the side for dipping. The bread's texture contrasts beautifully with the smooth soup, and its crust helps scoop up every last drop. I always recommend serving this soup while it's still steaming hot—this ensures the apples retain their subtle texture and the flavors are at their peak.
Real talk: the soup tastes even better the next day as the flavors meld further. Store any leftovers in an airtight container in the refrigerator for up to 3 days, or freeze for 3 months. Reheat gently on the stove with a splash of water or broth to restore its creamy consistency.
Pro Tips For Making Apple Celery Soup
- CHOP APPLES SMALLER THAN YOU THINK: I learned this the hard way—big chunks of Granny Smith make the soup look like a stew. Aim for ¼-inch dice so they soften evenly and release flavor without turning to mush. (Yes, even if you’re impatient like me, resist the urge to go big.)
- SWEAT THE ONION UNTIL IT’S ALMOST BROWN: Low and slow is the name of the game here. Cook the onion for 8-10 minutes until it’s just starting to caramelize—this builds depth that raw onion can’t match. If it smells sweet and sticky, you’re on the right track.
- SKIP THE CELERY SEEDS: Unless you’re going for a bitter kick, remove the stringy cores and tough outer leaves from the celery stalks. The tender inner ribs are what you want, and they’ll blend smoothly without adding unwanted texture. (Your future self will thank you.)
- STRAIN THE THYME STEMS: After simmering, pull out the thyme sprigs and give them a quick rinse under cold water to stop the cooking. Then, squeeze out the liquid from the stems—it’s packed with flavor that’ll make your soup taste like you spent hours on it. (Does it look weird? Yes. Does it work? Every single time.)
Best sauces and condiments for this apple celery soup
Herb-Infused Oil
Drizzle your soup with herb-infused olive oil just before serving for an aromatic finish. Heat ¼ cup extra-virgin olive oil with 1 tbsp fresh thyme leaves, 1 tsp minced garlic, and ½ tsp red pepper flakes in a small pan for 2 minutes on low heat.
Strain and drizzle over the soup—this adds a fragrant, garlicky depth that complements the apple and celery flavors beautifully. 🌿
Apple Cider Reduction
Simmer ½ cup apple cider with 1 tbsp maple syrup and 1 tsp lemon juice in a small saucepan until reduced to 2 tbsp (about 5 minutes). Swirl this glossy reduction into individual bowls of soup for a concentrated burst of apple flavor.
The natural sweetness and tang cut through the richness, balancing the herbal notes perfectly.
Crème Fraîche Variations
Replace the ¼ cup crème fraîche with these alternatives for different textures: vegan coconut yogurt (for tangy creaminess), sour cream (for extra richness), or mascarpone cheese (for a luxurious finish).
For a spiced twist, mix 1 tsp cinnamon or ½ tsp smoked paprika into the crème fraîche before serving—this adds warmth that pairs wonderfully with the apple.
Celery Seed Garnish
Toast ½ tsp celery seeds in a dry skillet for 1 minute until fragrant, then sprinkle over the soup for a nutty, earthy crunch. This garnish echoes the celery’s natural flavor while adding texture.
For a sweeter touch, top with toasted sliced almonds—they caramelize slightly and contrast the soup’s smoothness with a satisfying bite. 🌟
Spicy Apple Butter Swirl
Warm 1 tbsp apple butter (like Mott’s) with ¼ tsp cayenne pepper in a small saucepan for 1 minute, then swirl it into the soup. The smoky-sweet apple butter deepens the flavor profile while the cayenne adds a subtle kick.
This works especially well if you prefer your soup with a touch of heat and complexity.
Fresh Herb Garnishes
Brighten the soup with fresh herbs at the table: chopped chives (for mild onion notes), dill sprigs (for brightness), or microgreens (for a delicate crunch). For a pop of color, add edible flowers like nasturtiums—their peppery bite complements the apple’s sweetness.
Garnishes should be added just before serving to preserve their freshness and aroma. ✨

Frequently asked questions
Can I make this apple celery soup without apples?
The apples provide the subtle sweetness that balances the earthy celery, but you can substitute ½ cup diced pear or 1 small sweet potato for a similar effect. Just reduce the broth by ½ cup to maintain the right consistency. The apple cider vinegar should be replaced with ½ tsp lemon juice if using pears.
Why does my soup taste too bitter?
Overcooking the celery or apples can cause bitterness. Simmer the soup uncovered at low heat and avoid boiling vigorously. If it's too strong, balance it with 1 extra tablespoon apple cider vinegar or a pinch of sugar. The flour slurry should also be added carefully to prevent a starchy, bitter aftertaste.
How can I make this soup vegan?
Replace the butter with olive oil, use vegetable broth, and swap the crème fraîche for coconut yogurt or cashew cream. The flour slurry will still work, but for a gluten-free option, use cornstarch instead. The flavor remains rich and satisfying!
Can I prep this soup ahead of time?
Yes! Store the finished soup (without crème fraîche) in an airtight container for up to 5 days in the fridge. For freezing, portion into 2-cup servings and thaw overnight in the fridge. Reheat gently on the stove with a splash of water or broth to restore creaminess. The flavors actually deepen over time!
What's the best way to add texture?
For extra crunch, stir in ½ cup cooked quinoa or toasted breadcrumbs before serving. You can also add 1 cup diced apples (cooked separately) or crispy fried shallots on top. The contrast between smooth soup and crunchy toppings makes it even more satisfying!
