Ingredients for celery soup recipe instant pot
Celery, cream, and crispy croutons—this soup delivers two textures in one pot.
| Ingredient | Amount | Notes |
|---|---|---|
| Celery Stems 🧅 | 4 cups | Chopped into 1-inch pieces |
| Yellow Onion 🧅 | 1 whole | Diced, about 1 cup |
| Garlic Cloves 🧄 | 4 cloves | Minced, for deep flavor |
| Extra-Virgin Olive Oil 🫒 | ½ cup | For sautéing vegetables |
| Vegetable Broth 💧 | 4 cups | Low-sodium preferred |
| Heavy Cream 🥛 | 1 cup | Full-fat for richness |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Baguette 🍞 | 1 whole | Day-old, crusts removed |
| Parmesan Cheese 🧀 | ½ cup | Freshly grated, for topping |
| Fresh Thyme Leaves 🌿 | ¼ cup | Chopped, for garnish |
| Butter 🧈 | 2 tbsp | Unsalted, for croutons |
The celery is the star here, so grab the freshest bunch you can find—bright green stalks with no wilting. I always check the ends for any brown spots or softness. For the bread, Trader Joe's or Whole Foods carry great day-old baguettes, but any crusty loaf works. The Parmesan? Grate it yourself—pre-grated cheese gets clumpy and loses flavor. If you're short on time, the Kirkland brand from Costco is a solid budget pick. For the broth, low-sodium options are key so you can control the seasoning.
No fresh thyme? Dried works at one-third the amount, but it won't have the same bright flavor. Short on Parmesan? Pecorino Romano is a great swap—it's sharper and melts beautifully. The baguette can be any crusty bread, but avoid pre-sliced loaves—they're often too soft. For the croutons, toasted breadcrumbs are a quick alternative if you're in a rush. The lemon juice can be bottled in a pinch, but fresh is always better—Meyer lemons add a hint of sweetness that pairs perfectly with the celery.
The soup keeps beautifully in the fridge for 4-5 days, and the croutons stay crispy if you store them separately. Freeze the soup without the topping for up to 3 months—just add fresh croutons when reheating. For extra richness, stir in a splash of cream when serving. I always make a double batch—leftovers taste even better the next day, and the croutons can be toasted fresh whenever you're ready to eat.

Step-by-step instructions for celery soup with crispy topping
Here's how to make this velvety soup with golden croutons in your Instant Pot.
Sauté the Vegetable Base
Set your Instant Pot to the "Sauté" function and add the 0.5 cup extra-virgin olive oil. Once hot, add the 1 whole yellow onion and cook for 5 minutes until softened and translucent. Add the 4 cups chopped celery stems and cook for another 5 minutes, stirring occasionally, until the celery begins to soften.
Next, add the 4 cloves minced garlic and cook for 30 seconds until fragrant. You'll know it's ready when the kitchen fills with that irresistible garlic aroma. Be careful not to let it brown—just until it's perfumed. This step builds the flavor foundation for your entire soup.
Pressure Cook the Soup Base
Pour in the 4 cups vegetable broth, then add the 1 tsp salt and 0.5 tsp black pepper. Stir well to combine all ingredients. Secure the lid and set the Instant Pot to "High Pressure" for 8 minutes. This cooking time ensures the vegetables become tender while preserving their natural sweetness.
Once the cooking cycle completes, allow the pressure to release naturally for 10 minutes before quick-releasing any remaining pressure. This gradual release prevents the soup from becoming watery. The natural release also helps the flavors meld beautifully.
Blend to Creamy Perfection
Remove the lid and use an immersion blender to blend the soup until completely smooth. For the best texture, blend in batches if needed, ensuring no chunks remain. If you prefer a slightly thicker consistency, blend for an extra 10 seconds after it appears smooth.
Return the soup to the Instant Pot and stir in the 1 cup heavy cream and 2 tbsp lemon juice. The cream will give your soup that luxurious, velvety texture while the lemon juice brightens the flavors. Stir well to combine completely, then return the pot to "Sauté" mode and heat through for 2-3 minutes on low heat.
Prepare the Crispy Topping
While the soup heats, prepare the crispy croutons. Cut the 1 whole baguette into ½-inch cubes (about 4 cups). In a small skillet over medium heat, melt the 2 tbsp butter until foamy. Add the baguette cubes and cook for 3-4 minutes, stirring frequently, until golden brown and crispy.
Remove from heat and immediately sprinkle with 0.5 cup freshly grated Parmesan cheese and 0.25 cup chopped fresh thyme leaves. Toss gently to coat the croutons evenly. The cheese will melt slightly, adding extra flavor to each bite while keeping them crispy.
Serve with Crispy Topping
Ladle the creamy soup into bowls and top immediately with the crispy crouton mixture. The contrast between the velvety soup and crispy topping is what makes this recipe special. Each spoonful delivers that perfect balance of textures and flavors.
For extra richness, serve with additional grated Parmesan on the side. The soup tastes best fresh from the pot, so enjoy it while the croutons are still crispy. This one-pot meal delivers all the comfort of a classic French bistro dish with minimal effort.
Pro Tips For Making Celery Soup Recipe Instant Pot
- CHAR THE ONION FIRST: I learned this the hard way—sautéing onions with celery in the Instant Pot’s sauté function means the onions turn to mush before the celery even softens. Toss the celery in first, then add the onions after 2 minutes. They’ll caramelize properly while the celery gets a head start.
- SALT THE BROTH LIKE THE SOUP’S LIFE DEPENDS ON IT: That vegetable broth? Add an extra ½ teaspoon salt per cup right when you pour it in. The Instant Pot dilutes flavors, and celery soup needs boldness. Taste the broth before sealing—if it’s bland now, the soup will be sad later.
- PRESSURE-COOK FOR 8 MINUTES, NOT 5: Five minutes feels safe, but celery’s tough fibers need time to break down. Eight minutes guarantees creamy, melt-in-your-mouth texture without turning the soup into a mushy swamp. High pressure, not quick release—let it naturally decompress.
- SAVE TIME WITH FROZEN GARLIC: Fresh garlic burns in the Instant Pot’s sauté function, and chopped cloves take forever. Use 1 teaspoon of minced frozen garlic—it thaws instantly, adds depth, and won’t scorch. Your soup gets flavor without the stress.
