Ingredients for celery soup recipe instant pot
Celery roots, stems, and aromatic vegetables create this velvety velouté with crispy crowns.
| Ingredient | Amount | Notes |
|---|---|---|
| Celery Roots 🥬 | 2 lb | Whole, scrubbed, cut into chunks |
| Celery Stems 🥬 | 1 bunch | Thick, cut into 1-inch pieces |
| Yellow Onion 🧅 | 1 whole | Medium, chopped |
| Garlic Cloves 🧄 | 3 cloves | Fresh, minced |
| Vegetable Broth 💧 | 4 cups | Low-sodium preferred |
| Heavy Cream 🥛 | ½ cup | Full-fat for creaminess |
| Butter 🧈 | 2 tbsp | Unsalted, for topping |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Fresh Thyme 🌿 | 1 tbsp | Leaves only, chopped |
| Olive Oil 🫒 | 1 tbsp | For crisping celery crowns |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
Celery roots are the star here—look for firm, heavy roots at the grocery store (the bigger, the better). Trader Joe's and Whole Foods often carry them, but check the produce section. If you can't find celery roots, substitute extra celery stalks, though the texture will be slightly less velvety. Fresh thyme adds depth, so grab a small bunch—Costco sells it affordably in bulk. For the celery crowns, use the thickest stems you can find—they'll crisp up beautifully.
No celery roots? Double the celery stalks and add a pinch of salt to the broth to compensate for the lack of earthy sweetness. Fresh thyme unavailable? Dried thyme at one-third the amount works in a pinch. The heavy cream can be swapped for coconut milk for a lighter option, though it'll be slightly less rich. For extra depth, roast the garlic cloves before mincing—microwave 30 seconds with a splash of water for a caramelized flavor. The olive oil for crisping should be high-smoke-point, like avocado or light olive oil.
This soup reheats beautifully—just add a splash of broth or water. Store in an airtight container for up to 5 days in the fridge. For crispy celery crowns, make them fresh when serving—they lose crunch when reheated. Freeze the soup base (without crowns) for up to 3 months. To serve, simply reheat and crisp the celery crowns in a dry skillet with olive oil for 2-3 minutes until golden.

Step-by-step instructions for instant pot celery soup
Transform humble celery into a velvety, restaurant-quality soup with crispy crowns and rich depth.
Sauté Aromatics Until Fragrant
Set your Instant Pot to the "Sauté" function and add the 1 tablespoon olive oil. Once shimmering, add the 1 whole yellow onion and cook for 5 minutes until softened and translucent. Add the 1 bunch celery stems cut into 1-inch pieces and continue cooking for 4 minutes until the celery begins to soften.
This is where the flavor foundation builds. I like to press the celery stems gently with a wooden spoon—they'll release their sweet juices and mellow into the soup. Add the 3 cloves garlic cloves and 1 tablespoon fresh thyme at this stage, cooking for 30 seconds until the garlic is fragrant but not browned. The thyme leaves should be just beginning to release their piney aroma.
Add Celery Roots and Broth
Add the 2 lb celery roots cut into chunks to the pot. Stir to combine with the other vegetables, then pour in the 4 cups vegetable broth. Give everything a thorough stir to ensure all the celery roots are submerged and begin absorbing the liquid. This step is crucial for even cooking and maximum flavor extraction from the celery roots.
Secure the lid on your Instant Pot and set the valve to "Sealing." Cook on High Pressure for 10 minutes. The celery roots need this time to break down completely, creating that signature silky texture. If you peek during this time, you'll see the celery roots soften dramatically as they absorb the broth.
Blend Until Silky Smooth
Once the cooking cycle completes, allow the pressure to release naturally for 10 minutes before quick-releasing any remaining pressure. Remove the lid and use an immersion blender to purée the soup until completely smooth. I blend in batches if needed, ensuring no lumps remain. The soup should have a velvety consistency—like liquid silk.
This blending step transforms the soup from rustic to refined. If you prefer some texture, blend only until mostly smooth, but for that signature velouté, go for complete smoothness. Taste and adjust seasoning with the 1 teaspoon salt and ½ teaspoon black pepper at this stage, as the flavors will develop further during the cream stage.
Finish with Cream and Crispy Crowns
Return the pot to the "Sauté" function and stir in the ½ cup heavy cream and 2 tablespoons butter. Cook for 2-3 minutes until the soup is heated through and the cream is fully incorporated. The butter adds richness while the cream creates that luxurious mouthfeel. Keep the heat at medium-low to prevent curdling.
While the soup finishes, heat the 1 tablespoon olive oil in a small skillet over medium-high heat. Add the celery crowns (the leafy tops from the celery stems) and crisp for 2-3 minutes until golden brown. These crispy crowns add a delightful textural contrast that elevates the soup from ordinary to extraordinary.
Garnish and Serve Immediately
Ladle the soup into bowls and top each serving with a spoonful of crispy celery crowns and a sprinkle of ¼ cup fresh parsley. The parsley adds a fresh, bright note that cuts through the richness of the cream. Serve immediately while the crowns are still crisp—this soup tastes best fresh from the pot.
For an extra touch, I like to add a small dollop of cream on top of each serving just before it goes to the table. The contrast between the warm, velvety soup and the crispy crowns makes every bite exciting. This soup keeps well in the refrigerator for 3-4 days, but the crowns are best served immediately for maximum crunch.
Pro Tips For Making Celery Soup Recipe Instant Pot
- CHOP ONION SMALL: Cut that yellow onion into 1/4-inch dice—not thin slices—so it dissolves into the soup instead of turning to mush. I learned this the hard way after straining out onion bits that made the texture weird.
- SAUTE GARLIC LOW: Cook the garlic at medium-low heat until it’s golden, not browned. Burnt garlic tastes bitter, and you’ll regret it when the whole pot smells like a campfire instead of a cozy soup.
- USE FULL CELERY ROOT: Don’t peel the celery root—just scrub it clean and chop it with the skin on. The skin adds depth, and peeling wastes flavor (and time). Trust me, no one will notice the texture difference.
- PRESSURE COOK 15 MINUTES: Set the Instant Pot to high pressure for 15 minutes, not the quick setting. The celery root needs time to break down fully—rushing it leaves you with a watery, underwhelming broth.
Pro cooking tips for great celery soup recipe instant pot
Pressure Cooking Precision
The 10-minute high-pressure cook is non-negotiable for perfect celery root texture. Celery roots need this time to break down completely into a velvety purée—any less, and you'll end up with chunks. I've tested shorter times, and the results are always disappointing.
Use the natural release for the first 10 minutes to allow the steam to work its magic before quick-releasing. This two-step release prevents the soup from becoming watery and ensures the celery roots soften evenly. 🌡️
Immersion Blender Magic
An immersion blender is your best friend here—it keeps the soup in the pot where it belongs. I blend in two batches if needed, ensuring no lumps remain. For that signature restaurant-quality velouté, aim for completely smooth texture.
If you're using a countertop blender, let the soup cool slightly first to prevent splattering. The key is patience—rushing the blending process can leave you with a gritty texture that ruins the silky finish.
Cream Timing Matters
Add the ½ cup heavy cream and 2 tbsp butter only after the soup has been blended and seasoned. Heating the cream directly in the pot can cause it to curdle if the soup is too hot.
Keep the heat at medium-low and stir constantly for 2-3 minutes until fully incorporated. This gentle approach ensures a creamy, velvety finish without breaking the emulsion. The butter adds richness, but don’t overcook it—just until melted and silky.
Celery Crown Crisp
The celery crowns are the showstopper—don’t skip this step! Use the thickest, leafiest parts of the celery stems, cut into 1-inch pieces. Heat 1 tbsp olive oil in a small skillet over medium-high heat until shimmering, then crisp for 2-3 minutes until golden brown.
The crowns should be crispy yet tender—not burnt. Serve immediately to maintain that satisfying crunch, as they soften quickly once removed from heat. 🔥
Seasoning Adjustments
Taste the soup after blending but before adding cream—this is when you can properly assess the seasoning. The celery roots and broth often need a ½ tsp more salt and a pinch of black pepper to balance flavors.
The cream will mellow the taste slightly, so don’t be shy with seasoning now. For extra depth, add a pinch of nutmeg or a splash of lemon juice at the end. The goal is a well-rounded, harmonious flavor that lets the celery shine.
Altitude Adjustments
If you live above 3,000 feet, increase the pressure cook time by 2-3 minutes to account for lower atmospheric pressure. The soup needs that extra time to reach the same silky texture. Always use the high-pressure setting—never low—because celery roots require the higher heat to break down properly.
For high-altitude cooking, I also recommend adding an extra ¼ cup broth to prevent the soup from becoming too thick. The Instant Pot’s pressure adjustment feature helps, but manual tweaks ensure perfection. ⚡
Nutrition facts
Frequently asked questions
Can I make this celery soup without celery roots?
Yes! Use 6-8 extra celery stalks (about 2 pounds total) instead of celery roots. Add a pinch of salt to the broth to compensate for the lack of earthy sweetness. The texture will be slightly less velvety but still delicious. For best results, roast the extra celery stalks at 400°F for 15 minutes before adding to the pot to deepen the flavor.
Why does my Instant Pot celery soup turn out watery?
Watery soup usually means the celery roots didn't cook long enough or the pressure released too quickly. Always use a 10-minute high-pressure cook with a 10-minute natural release first. If it's still too thin, simmer uncovered on "Sauté" mode for 3-5 minutes to reduce. For extra richness, stir in 1-2 tablespoons cornstarch mixed with water until thickened.
How can I make this soup dairy-free?
Replace the ½ cup heavy cream with ½ cup full-fat coconut milk for a dairy-free version. The soup will be slightly lighter but still creamy. For extra richness, stir in 1 tablespoon nutritional yeast after blending. Keep the 2 tablespoons butter optional—substitute with 2 tablespoons olive oil if needed. The flavor remains robust without dairy.
Can I prep this soup ahead of time?
Make the soup base (without cream or celery crowns) up to 5 days ahead and store in an airtight container. Reheat gently on the stove or in the microwave, then finish with fresh cream and crispy crowns just before serving. For the crowns, make them fresh when ready to eat—they lose crunch when reheated. The soup base freezes beautifully for up to 3 months.
What's the best way to crisp the celery crowns?
Use the thickest, leafiest parts of celery stems, cut into 1-inch pieces. Heat 1 tablespoon olive oil in a skillet over medium-high heat until shimmering. Add crowns in a single layer and cook for 2-3 minutes, stirring occasionally, until golden brown. They're done when crispy yet tender—don't let them burn! Serve immediately for maximum crunch.
