Ingredients for arash hashemi tomato soup
Simple ingredients elevated by technique—San Marzano tomatoes, fresh herbs, and slow simmering create restaurant-quality tomato soup.
| Ingredient | Amount | Notes |
|---|---|---|
| San Marzano Tomatoes 🍅 | 28 oz | Canned, whole or crushed |
| Yellow Onion 🧅 | 1 whole | Medium size, diced |
| Garlic Cloves 🧄 | 4 cloves | Fresh, peeled, minced |
| Extra-Virgin Olive Oil 🫒 | ½ cup | High quality, fruity |
| Fresh Basil Leaves 🌿 | ½ cup | Packed, stems removed |
| Fresh Thyme Leaves 🌿 | ¼ cup | Packed, stems removed |
| Heavy Cream 🥛 | ¼ cup | Full-fat for richness |
| Vegetable Broth 💧 | 2 cups | Low-sodium preferred |
| Salt 🧂 | 1 tsp | Diamond Crystal preferred |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Sugar 🍚 | 1 tbsp | White granulated |
| Red Wine Vinegar 🍷 | 1 tbsp | For brightness |
| Crusty Bread 🍞 | 4 slices | For serving |
San Marzano tomatoes are the foundation—look for the official DOP label at Whole Foods or Italian markets for that signature sweetness. Fresh basil and thyme should be vibrant, not wilted; Trader Joe's carries great pre-packaged bundles. The onion and garlic are non-negotiable for depth—don’t skip browning them. For the olive oil, California brands like Corto or Ottolenghi deliver that fruity punch. And that heavy cream? Full-fat is essential—it’s what gives the soup its velvety texture. Skip the low-fat version, trust me.
No San Marzano tomatoes? High-quality crushed tomatoes in a can work in a pinch, but you’ll miss that depth. Fresh herbs wilt fast—dried basil at one-third the amount gets you close if needed. The vegetable broth should be low-sodium; Pacific Foods or Imagine are solid choices. For the sugar, you can swap in honey or maple syrup, but it’ll change the flavor profile slightly. The red wine vinegar adds brightness—if you’re avoiding alcohol, apple cider vinegar works too. And if you’re watching calories, Greek yogurt thinned with broth replaces the cream beautifully.
This soup tastes even better the next day—reheats perfectly in 2-3 minutes. Store leftovers in an airtight container for up to 5 days in the fridge, or freeze for 3 months. For serving, toast the crusty bread until golden—sourdough or a good baguette cuts through the richness. Garnish with extra basil and a drizzle of olive oil right before serving; that’s where the restaurant-quality magic happens.
Why You'll Love This Recipe
- No-Fuss Foundation: I swear by this as my "oh crap, I forgot to meal prep" backup—just peel those San Marzano tomatoes (or toss 'em whole if you're lazy), simmer with onion and garlic in olive oil, and let the flavors meld. The onions caramelize while you're still deciding what to watch on TV.
- Sunshine in a Bowl: That first sip of bright, tangy tomato with just a whisper of garlic and basil? It’s like summer in a mug, but without the bugs. The San Marzano tomatoes give it that natural sweetness that makes you forget you’re eating soup—until you take another spoonful and realize how good it actually is.
- Leftover Lifesaver: This soup only gets better the next day—thicker, richer, and somehow even more comforting. I make a double batch on Sundays, freeze half, and pull it out for those nights when I’m too tired to cook. (Between us, I’ve lived on this for weeks.)
- Budget Brightener: Fresh basil and San Marzano tomatoes might sound fancy, but they stretch like crazy. A single jar of crushed tomatoes (or a handful of fresh) and a bunch of basil from the grocery store’s $1 bin turn into enough soup to feed four. Honestly, it’s my go-to when I’m trying to make groceries last longer.
Step-by-step instructions for Arash Hashemi's tomato soup
Transform simple ingredients into a restaurant-worthy tomato soup with velvety texture and vibrant herbed freshness.
Sauté Aromatics Until Fragrant
Heat the 0.5 cup extra-virgin olive oil in a large pot over medium heat. Add the 1 whole yellow onion, diced into ¼-inch pieces, and cook for 5-6 minutes until softened and translucent. Stir occasionally to prevent burning.
Add the 4 cloves minced garlic and cook for another 30 seconds until the garlic releases its aroma but doesn't brown. This step builds the flavor foundation—don't rush it. The onions should be completely tender with no crunch remaining.
Build the Tomato Base
Pour in the 28 oz San Marzano tomatoes (crushed by hand if using whole tomatoes) and stir to combine with the onions and garlic. Add the 2 cups vegetable broth, 1 tbsp sugar, and 1 tbsp red wine vinegar. Bring the mixture to a gentle boil, then reduce heat to medium-low and let it simmer uncovered for 20-25 minutes.
During this time, the tomatoes will break down into a smooth consistency. Stir occasionally to prevent sticking. You're looking for a thickened sauce that coats the back of a spoon. The acidity from the vinegar and sweetness from the sugar will balance the natural tartness of the tomatoes.
Season and Blend to Perfection
Season the soup with 1 tsp salt and 0.5 tsp ground black pepper, then stir in the 0.5 cup fresh basil leaves and 0.25 cup fresh thyme leaves. Let the soup simmer for an additional 5 minutes to allow the herbs to infuse their flavors.
For a completely smooth texture, carefully transfer the soup to a blender or use an immersion blender directly in the pot. Blend until silky smooth, scraping down the sides as needed. Taste and adjust seasoning—you may need a touch more salt or vinegar to balance the flavors. The soup should be velvety with no visible chunks.
Finish with Cream and Serve
Return the blended soup to the pot and stir in the 0.25 cup heavy cream over low heat. Warm through for just 1-2 minutes—don't let it boil or the cream will curdle. The soup should be creamy but not heavy, with a glossy sheen on the surface.
Ladle the soup into bowls and serve immediately with the 4 slices crusty bread. The contrast between the warm, velvety soup and the crisp bread creates the perfect textural experience. Each spoonful should deliver a balance of sweet, tangy, and herby flavors with a luxurious creaminess.
Pro Tips For Making Arash Hashemi Tomato Soup
- CRUSH THE ONIONS: Use a food processor for the yellow onion—pulse it until it’s almost paste, but not quite. I used to chop by hand and wondered why my soup never had that deep, sweet base. The processor breaks down the fibers just enough to melt into the tomatoes faster without turning to mush.
- SIMMER LOW AND SLOW: Once the tomatoes hit the pot, reduce heat to a bare simmer—think tiny bubbles, not rolling. I learned this the hard way after one batch turned into a watery, skinned mess. A steady 30-45 minutes at low heat lets the flavors marry without breaking down the texture.
- SALT THE WATER FIRST: Add a generous pinch of salt to the water before blanching the tomatoes (if using whole). It seasons the skins so they crisp up nicely when toasted—no more bland, rubbery bits. Trust me, it’s the thing that makes the difference between "good" and "restaurant-quality."
- TOAST THE GARLIC DRY: Pull the pan off heat just before the garlic turns golden—it’s done when it smells nutty, not burnt. I was skeptical until I tried it (yes, even if you’re impatient like me). Overcooked garlic turns bitter, and that flavor lingers in the soup.
Make-ahead tips for this arash hashemi tomato soup
Prep Ahead for Smooth Soup
Start by prepping all your ingredients the night before—dice the 1 yellow onion and mince the 4 garlic cloves—then store them in airtight containers in the fridge. This saves 15 minutes of prep time the next day.
The San Marzano tomatoes and vegetable broth can also be measured out ahead of time for seamless cooking. 💡
Slow Simmer for Depth
For maximum flavor, simmer the tomato base on low heat for 45-60 minutes the day before you plan to serve. This extended cooking time deepens the natural sweetness and allows the herbs to infuse more thoroughly. Just reheat gently on the stovetop or microwave before blending and adding the cream.
Herb Infusion Shortcut
Make an herb infusion by steeping 0.5 cup fresh basil and 0.25 cup fresh thyme in 1 cup hot vegetable broth for 10 minutes the night before. Strain and store in the fridge.
When you're ready to cook, simply add this infused broth to your soup for instant herbaceous flavor without needing to simmer the fresh herbs directly.
Creamy Base Prep
Combine the 0.25 cup heavy cream with 1 tbsp red wine vinegar and 1 tsp salt in a small bowl and refrigerate overnight.
This pre-mixed cream blend can be stirred directly into your soup at the end, ensuring perfect balance and saving you from measuring multiple ingredients during the final step. 🥛
Freezer-Friendly Blending
Blend the soup base (without cream) up to 3 days ahead and freeze in airtight containers. When ready to serve, thaw overnight in the fridge, then reheat on the stovetop.
Just stir in the cream and fresh herbs at the end to revive the vibrant flavors. This method preserves the velvety texture perfectly.
Bread Prep for Serving
Toast your 4 slices crusty bread the night before and store in a paper bag at room temperature. This keeps them crisp for up to 24 hours.
Warm them in the oven at 350°F for 5 minutes before serving to maintain their perfect crunch. The contrast with warm soup is unbeatable! 🍞

Frequently asked questions
Can I use regular canned tomatoes instead of San Marzano?
While San Marzano tomatoes deliver that signature sweetness and smooth texture, you can substitute with high-quality crushed tomatoes in a pinch. For best results, choose brands with minimal additives and add an extra ½ teaspoon of sugar to compensate for any tartness. The flavor won't be identical, but it'll still be delicious!
Why does the soup need to simmer so long?
The extended simmering (20-25 minutes) is key to developing deep, complex flavors by breaking down the tomatoes' natural sugars and acids. This creates that velvety texture and balanced sweet-tart profile. Skipping this step results in a thinner, less flavorful soup—patience pays off!
What if I don't have an immersion blender?
No problem! Transfer the hot soup to a blender in batches (don't overfill), blending until completely smooth. For safety, leave a little space at the top and use caution with hot liquids. Just be sure to cool the soup slightly first to prevent steam buildup.
Can I make this soup vegetarian or vegan?
For a vegan version, replace the heavy cream with ¼ cup coconut cream or ½ cup cashew cream (blended soaked cashews with water). Use vegetable broth throughout, and the recipe remains fully plant-based while keeping that creamy texture.
How do I store leftovers to keep them tasting fresh?
Store in an airtight container in the fridge for up to 5 days. For reheating, warm gently on the stovetop over low heat (never microwave directly) and stir in a splash of water if it thickens too much. The flavors actually improve overnight!
