Ingredients Needed

• 2 cups potatoes, sliced into ½ inch thick rounds ( about ¾ lb –  1 extra-large russet peeled, or use a few yukons, unpeeled.
• 4 cups veggie or chicken broth ( or 4 cups water + 1 tablespoon “Better than Bouillon” Vegetable Base)
• 1 cup water
• 1 bay leaf (optional), remove it before blending
• 1 teaspoon salt
• ½ teaspoon pepper
• 1/8 – 1/4 teaspoon cayenne, start conservatively, add more to taste or leave it out entirely.
• ¼ cup fresh dill (small stems ok)
• ½ cup fresh parsley (small stems ok)

Ingredient Notes & Substitutions

Let’s dive into the ingredients and explore some handy substitutions.

Olive oil vs. Butter: Use high-quality olive oil for a vibrant, slightly peppery flavor, or opt for butter for a richer, more decadent taste. The choice is yours!

Broth: Vegetable broth keeps this soup vegan, while chicken broth adds a deeper savory note. I often use “Better than Bouillon” Vegetable Base mixed with water for a quick and flavorful option. Be mindful of sodium levels and choose low-sodium options if needed.

Potatoes: Yukon Gold potatoes are fantastic for their creamy texture. If you’re looking for a lower-carb alternative, consider cauliflower or parsnip. These swaps will subtly alter the flavor, but still provide a lovely creamy base. Explore more Variations and Swaps.

Dairy: For a classic creaminess, sour cream or heavy cream works wonders. To keep things vegan, vegan sour cream or cashew cream are excellent substitutes. Each option will affect the final flavor and texture, so experiment to find your favorite!

Herbs: Fresh dill and parsley are my go-to for their bright, herbaceous flavor. If you only have dried herbs on hand, use about 1 teaspoon of each, as dried herbs are more concentrated.

How to Make Celery Soup

Follow these simple steps to create a delicious and comforting celery soup.

Step 1: Sautéing Aromatics

Heat the olive oil (or butter) in a large pot over medium-high heat. Add the diced onion and stir occasionally, allowing it to caramelize. You’ll know it’s ready when the onions turn a beautiful golden brown and release a sweet, fragrant aroma. This process, known as the Maillard reaction, is key to building depth of flavor in your soup. It takes about 5 minutes. Learn more about the Maillard reaction.

Step 2: Adding Garlic

Add the rough-chopped garlic to the pot and stir for just 1-2 minutes, until fragrant. Be careful not to burn the garlic, as this will make it bitter.

Step 3: Simmering

Add the sliced celery, potatoes, broth (or water and bouillon), bay leaf (if using), salt, pepper, and cayenne to the pot. The liquid should just cover the vegetables. If needed add a little more water, careful not to drown the veggies. Cover the pot, bring to a rolling boil, then reduce the heat and simmer gently until the potatoes are tender, about 10 minutes.

Step 4: Adding Herbs

Turn off the heat, remove the bay leaf, and add the fresh dill and parsley. Just wilt them by stirring into the hot soup; don’t cook them, or you’ll lose their vibrant color and fresh flavor.

Step 5: Blending

Using an immersion blender, blend the soup until it’s very silky smooth. If using a regular blender, let the soup cool slightly before blending it in smaller batches. When blending warm soup, fill the blender no more than halfway, cover tightly with the lid and a kitchen towel, and hold it down firmly when you start the motor on the lowest setting, working up gradually to prevent a blender “explosion.” Blend well, for a full minute, until the herbs are fully incorporated, creating a vibrant-colored soup. For an extra boost of green color, add a handful of raw baby spinach if you like, or more fresh parsley.

Step 6: Finishing

Place the blended soup back into the same pot over low heat. Stir in your choice of sour cream, vegan sour cream, heavy cream, or cashew cream. Gently heat, being careful not to over-simmer, as this may cause the color to fade or the dairy to curdle.

Step 7: Crispy Celery Leaves (Optional Garnish)

To make crispy celery leaves, heat a generous amount of olive oil in a small skillet over medium heat. Wait until the oil is hot. You can test this by frying a “tester” celery leaf for 10-20 seconds on each side. Set it on a paper towel. If it is crisp, continue on. Add a few leaves at a time, not overly crowding the pan. If they’re not crisp, fry them a little longer. You want about 3-5 leaves per serving bowl. In the same oil, you could fry the nigella seeds until you just begin to hear popping. Turn off the heat. Arrange the crispy celery leaves in a crescent shape on top of the soup. Spoon a little of the nigella seeds along with a little oil in the same shape. Sprinkle with hemp seeds if you like.

Achieving Silky Smooth Texture

The key to a truly exceptional celery soup is its texture. Here’s how to ensure yours is perfectly smooth:

Thoroughly Cooked Vegetables: Make sure the celery and potatoes are cooked until very tender before blending.

High-Powered Blender: Use a high-powered blender, whether an immersion blender or a regular blender, for the best results.

Sufficient Blending Time: Blend the soup for at least 1 minute to fully break down the vegetables and herbs.

Creamy Finish: Adding a touch of cream or cashew cream at the end contributes to a smoother, more luxurious texture.

Troubleshooting: If the soup is still slightly grainy after blending, blend it for a longer time. For an ultra-smooth texture, consider straining the soup through a fine-mesh sieve.

Pro Tips & Troubleshooting

Here are some expert tips and common mistakes to avoid for the best celery soup every time.

Pro Tips

• Thinly slice the celery for even cooking and to prevent stringiness.
• Sauté the onions until they are golden brown to develop a deeper flavor.
• Don’t over-simmer the soup after adding the cream to prevent curdling or color loss.
• For a vegan version, use cashew cream or another plant-based cream alternative.
• Add the lemon juice and red pepper flakes *after* blending to preserve their brightness and flavor.
• Taste and adjust the seasoning (salt, pepper, cayenne) to your preference.
• If using an immersion blender, start at the lowest setting to avoid splattering.

Common Mistakes to Avoid

• Over-simmering the soup after adding dairy (can cause curdling).
• Not blending the soup long enough (results in a grainy texture).
• Overfilling the blender when blending hot soup (can cause a blender explosion – be careful!).
• Burning the garlic during sautéing (leads to a bitter taste).
• Not seasoning the soup properly (can result in a bland flavor).
• Not removing the bay leaf before blending.

Serving & Storage

Here’s how to best enjoy and store your delicious celery soup.

Serving Ideas

Garnish with crispy celery leaves, nigella seeds, and hemp seeds for a beautiful presentation and added flavor. Serve with crusty bread for dipping, or add croutons, halloumi croutons, or millet croutons for added texture. Pair with a side salad or grilled cheese sandwich for a complete meal. Other topping ideas include fresh herbs, a swirl of cream, or a sprinkle of red pepper flakes.

Storage and Make-Ahead

Fridge: The soup can be stored in the refrigerator for up to 3-4 days in an airtight container.

Freezer: For longer storage, freeze the soup in individual portions. To prevent a grainy texture after thawing, cool the soup completely before freezing, use freezer-safe containers, and leave some headspace in the container.

Reheating: Reheat gently on the stovetop or in the microwave. If frozen, thaw overnight in the refrigerator before reheating. Consider blending the soup again after thawing for the best texture.
