Passato di verdura is an Italian pureed vegetable soup made by simmering soffritto, potato, carrot, zucchini and peas in water, then blending until smooth. This version takes an hour from first chop to bowl and uses no cream.
The texture, not the cream, defines the result. Potato starch gives a silky body that coats the spoon, so a drizzle of raw olive oil at the end is all the richness it needs.
I use a food mill when I’m not rushed, because it holds back celery fibers and stray skin. An immersion blender works fine if you stop at about 60 seconds. Go longer and the potato turns gluey.
It’s a weeknight soup that tastes better the next day, and it freezes in portions.
Why You’ll Love This Recipe
- Potato gives silky body with no cream
- Uses ordinary vegetables, including frozen peas
- One pot with about 15 minutes of chopping
- Freezes in portions for up to 3 months
Ingredient Notes
- Potatoes: Yukon Gold gives the cleanest, buttery taste and a smooth finish. Russet works but breaks down faster and turns slightly grainier.
- Frozen peas: Practical pantry note: frozen peas work year-round and keep the soup’s color bright. Add them straight from the freezer for the last 5 minutes.
- Zucchini: Choose small, firm zucchini with tight skin. Large ones are watery and can make the soup taste flat.
- Parmigiano rind: The rind adds savory depth as it simmers. Skip it for a vegan version and add a small pinch more salt.
- Extra virgin olive oil: Use a fruity one for the finishing drizzle, since it’s tasted raw. A plainer oil is fine for the soffritto.
Passato di Verdura: Silky Pureed Italian Vegetable Soup
Ingredients
Method
- Prep the vegetables as listed. Heat 2 tbsp olive oil in a 5-quart / 4.7 L heavy-bottomed pot over medium-low heat. Add the onion, celery and carrot with a pinch of salt and cook for 8 minutes, stirring often, until the onion is translucent and nothing has browned.
- Stir in the potatoes and zucchini and cook for 2 minutes. Add the water, the remaining salt and the Parmigiano rind if using. Bring to a boil over high heat, about 5 minutes, then lower to a gentle simmer, partly cover, and cook for 25 minutes. Add the frozen peas for the last 5 minutes. The potato is ready when it breaks apart against the side of the pot.
- Remove the rind. Blend with an immersion blender for about 60 seconds until smooth, or pass the soup through a food mill with the fine disk. In a countertop blender, work in two batches, fill it only halfway and vent the lid. Longer blending turns the potato gluey. If the soup is too thick, stir in hot water 50 ml at a time until it ribbons off the spoon.
- Return the pot to low heat and taste, adding salt if needed. Ladle into warm bowls, drizzle with the remaining 1 tbsp olive oil, then top with the grated Parmigiano, torn basil and black pepper.
Notes
- Use a 5-quart pot so the vegetables stay covered by water while they simmer.
- Blend for about 60 seconds only, so the potato doesn't turn gluey.
- Salt in two stages, a pinch with the soffritto and the rest in the water, then taste after blending.
- Leave cheese and basil off anything you plan to freeze.
Tips for Success
- Cut the potato and zucchini into 2 cm pieces and dice the carrot at 1 cm so everything softens at the same pace.
- Sweat the soffritto over medium-low heat for 8 minutes and stop before it browns, since color turns the soup muddy.
- Thin with hot water only at the end, 50 ml at a time, because the soup tightens as it cools.
- Use a food mill with the fine disk when you have time, since it catches celery fibers and any leftover skin.
- Save Parmigiano rinds in the freezer and drop one into the pot, where it adds savory depth without extra salt.
Variations
- Stir in 200 g drained cannellini beans before blending for extra body and protein.
- Swap the zucchini for 250 g peeled pumpkin or butternut squash in autumn for a sweeter, deeper orange soup.
- Skip the Parmigiano rind and cheese, then finish with extra olive oil and a little lemon zest for a vegan bowl.
Storage and Reheating
Passato di verdura keeps in an airtight container in the fridge for 3-4 days. Cool it within 2 hours of cooking, and leave off the Parmigiano and basil until you serve.
For the freezer, portion it into containers with 2 cm of headspace and freeze for up to 3 months. Thaw overnight in the fridge.
Reheat on the stovetop over medium-low heat for 8 to 10 minutes, stirring often, until it bubbles gently at the edges. The soup thickens as it sits, so add 2 to 3 tbsp water per portion. In the microwave, cover and heat at 70% power for 2 to 3 minutes, stirring halfway.
Serving Suggestions
Serve passato di verdura hot, with a drizzle of olive oil, a grind of black pepper and a little grated Parmigiano. Tear a few basil leaves over the top at the last second.
Toasted bread rubbed with a cut garlic clove is the usual partner. A soft-boiled egg on top turns a bowl into a light dinner.
It also works in a thermos for lunch. Pour it in boiling hot and it stays warm until noon.
FAQ
Why is my passato di verdura gluey instead of silky?
Passato di verdura turns gluey when the potato is blended too long, because the starch releases and makes the texture stretchy. Stop the immersion blender after about 60 seconds, or use a food mill instead. If it’s simply too thick, stir in 50 ml hot water at a time until it ribbons off the spoon.
Can I use russet or sweet potatoes instead of Yukon Gold in passato di verdura?
Yes, russet potatoes work, but they break down faster and give a slightly grainier, thicker soup, so thin it at the end if needed. Sweet potato also blends smoothly but makes the soup sweeter and orange. I still prefer Yukon Gold for its clean, buttery taste.
Can I freeze passato di verdura that has potato in it?
Yes, it freezes well for up to 3 months because the potato is already pureed, so there’s no grainy texture to worry about. Freeze it in portions with 2 cm of headspace and without the Parmigiano or basil. Thaw overnight in the fridge and warm it on the stove with a splash of water.
What goes well with passato di verdura to make it a full dinner?
Toasted bread rubbed with a cut garlic clove is the usual partner. A soft-boiled egg on top, or a handful of cooked small pasta stirred in, turns it into a meal. A wedge of Parmigiano and a green salad with lemon dressing finish the table without much extra work.
Is passato di verdura gluten free, and can I make it vegan?
Passato di verdura is gluten-free as written, since the body comes from potato and not flour or bread. It does contain dairy from the Parmigiano. For a vegan bowl, skip the rind and the grated cheese, add a small pinch more salt, and finish with an extra drizzle of olive oil.
What is the difference between passato di verdura and minestrone?
Passato di verdura is blended until smooth, while minestrone, like this Valtellina minestra with beans and cabbage, keeps the vegetables in chunks and usually adds beans or pasta. A vellutata is a related smooth soup, often built on one main vegetable, like the pumpkin in a silky Italian pumpkin rice soup. Passato uses a mix of whatever vegetables you have, with potato as the thickener.
