This isn't your grandmother's soup—it's a modern interpretation that balances silky texture with bold, aromatic flavors, all achieved through precise technique and high-quality ingredients.

The secret lies in slow simmering to develop depth while maintaining that restaurant-quality smoothness.

What sets this recipe apart is the crispy celery crown—a delicate yet dramatic garnish that adds both visual appeal and satisfying texture contrast.

Unlike traditional tomato soups that rely on heavy cream or butter, this version uses olive oil and fresh herbs to build flavor, creating a dish that's rich without being overly heavy.

The celery crown transforms simple celery stalks into edible garnishes that shatter with each bite, adding a satisfying crunch to the smooth soup base.

By the time you're done, you'll have a bowl of soup that's silky smooth with layers of umami from caramelized aromatics, brightened by fresh basil and finished with that signature crispy crown.

Ingredients for arash hashemi tomato soup

High-quality ingredients create Arash Hashemi's signature velvety tomato soup with crispy celery crown topping.

The San Marzano tomatoes are non-negotiable here—their natural sweetness and low acidity create that velvety texture. Grab a 28-ounce can at specialty stores or the Italian section of Whole Foods. For the celery crown, look for firm, pale green stalks with no browning at the base. The vegetable stock should be homemade if possible, but Pacific Foods or Imagine brands are solid store-bought options. Fresh basil is ideal, but dried oregano at half the amount works in a pinch—just don't skip the thyme entirely, as it's the backbone of the aromatic base.

No San Marzano tomatoes? Crushed tomatoes in a high-quality jar will work, but you'll need about 2 cups instead. The celery crown can be made with leeks or fennel bulbs for variation, though celery's crisp texture is unmatched. For the crispy coating, crushed cornflakes add extra crunch without altering flavor. The Parmesan is optional but adds a nice umami depth—nutritional yeast makes a great vegan alternative. Always toast your breadcrumbs lightly before using; a dry pan over medium heat for 2-3 minutes brings out their flavor.

Fresh herbs like basil and thyme should be stored in damp paper towels in sealed containers—they'll stay fresh for 5-7 days. The tomato paste keeps for 18 months unopened, but once opened, transfer it to a jar and refrigerate for up to 6 months. Celery crowns can be prepped 2 days ahead and stored in an airtight container; simply reheat in the oven at 375°F for 5-7 minutes before serving. The soup base freezes beautifully—portion into containers and it'll keep for 3 months without losing its silky texture.

Step-by-step instructions for Arash Hashemi's tomato soup

Here's how to create a velvety tomato base with a perfectly crisp celery crown topping.

Heat the 0.5 cup extra-virgin olive oil in a large Dutch oven over medium heat until shimmering. Add the 1 whole yellow onion, 3 medium carrots (sliced into rounds), and 3 whole celery stalks (chopped into ½-inch pieces). Cook for 8-10 minutes until the vegetables soften and the onion becomes translucent.

I press the vegetables down occasionally with a wooden spoon to ensure even cooking. This prevents any pieces from burning while others remain undercooked. The celery should release its natural oils and develop a golden hue at the edges.

Reduce the heat to medium-low and add the 4 cloves minced garlic, cooking for 30 seconds until fragrant. Stir in the 0.5 cup San Marzano tomato paste and cook for 2 minutes to deepen its flavor.

Gradually pour in the 4 cups vegetable stock while stirring to prevent lumps. Add the 1.5 tsp salt, 1 tsp dried thyme, and 0.5 tsp cracked black peppercorns. Bring the mixture to a gentle simmer, then reduce heat to low and let it cook uncovered for 20 minutes to develop rich, concentrated flavors.

Remove the soup from heat and let it cool for 5 minutes. Using an immersion blender, blend until completely smooth. For a perfectly silky texture, I blend in batches if needed, ensuring no lumps remain. The soup should have a velvety consistency with no visible vegetable pieces.

Return the soup to the pot and stir in the 0.5 cup chopped fresh basil leaves. Taste and adjust seasoning if needed. Keep the soup warm over low heat while you prepare the celery crown topping.

In a small bowl, combine the 2 tbsp all-purpose flour, 0.5 cup panko breadcrumbs, and 0.25 cup freshly grated Parmesan cheese. Cut the 3 whole celery stalks lengthwise into thin strips (about ¼-inch thick) and dip each piece into the flour mixture, pressing gently to adhere.

Arrange the coated celery strips in a single layer on a parchment-lined baking sheet, leaving space between each piece. Bake at 400°F for 12-15 minutes until golden brown and crispy. Flip halfway through for even browning.

Ladle the warm tomato soup into bowls and arrange the crispy celery crowns on top. The contrast between the silky soup and crunchy topping is what makes this dish special. Serve immediately while the celery remains crispy and the soup stays warm.

For an extra touch, garnish with additional fresh basil leaves. The celery crown should hold its shape and provide a satisfying crunch with each bite, balancing the smooth tomato base perfectly.

Troubleshooting this recipe

Lumpy Texture Fix

If your soup turns out lumpy despite blending, don't panic! Return it to the pot and add ¼ cup water or vegetable stock, then simmer for 5 minutes to break down any remaining chunks.

For extra smoothness, I like to strain the soup through a fine-mesh sieve after blending—this ensures a completely velvety texture. The key is patience: blend in 10-second bursts until perfectly smooth. 💫

Celery Crown Too Soft

If your celery crowns lose their crispiness, they likely didn't bake long enough or were overcrowded on the sheet. For next time, bake at 400°F for 15-18 minutes and leave 1 inch of space between pieces.

I also recommend using a wire rack over a baking sheet to allow air circulation on both sides. If they soften after baking, pop them back in the oven for 2-3 minutes to restore crispness.

Overly Acidic Flavor

The soup might taste too acidic if you used regular canned tomatoes instead of San Marzano. To balance the acidity, add 1 tsp sugar or honey while simmering or stir in ½ cup heavy cream at the end for richness.

For a vegetarian option, use ½ cup coconut milk instead. I also find that simmering the soup uncovered for an extra 5-10 minutes helps mellow out any sharp flavors.

Weak Celery Flavor

If your celery crowns lack flavor, you may have missed the celery's natural oils during sautéing. For deeper flavor, add 1 tsp soy sauce or miso paste to the flour mixture before coating the celery.

Another trick is to blanch the celery strips in boiling water for 30 seconds before coating—they'll absorb more flavor from the mixture. I also recommend using green celery instead of white for a more robust taste.

Soupy Consistency

If your soup is too thin, simmer it uncovered for 10-15 minutes to reduce the liquid. For a quicker fix, stir in 1 tbsp cornstarch mixed with 2 tbsp cold water and simmer for 2 minutes until thickened.

Avoid over-blending, as this can make the soup thinner. The ideal consistency should coat the back of a spoon but still be easy to ladle. 🥄

Burnt Aromatics

Burnt onions or carrots can ruin the delicate flavors of this soup. To prevent this, keep the heat at medium-low while sautéing and stir frequently. If you notice any browned bits, remove them immediately with a slotted spoon.

For extra insurance, I like to add a pinch of salt to the oil before heating—this helps regulate the cooking temperature and prevents burning. 🔥
