Zucchini Soup with Star Anise, No Cream or Potatoes
This zucchini soup gets its smooth, light texture from the vegetables themselves, with softened onions, chicken stock and whole star anise for a warm, distinctive aroma. Weighing the zucchini keeps the broth proportion consistent. The spice stays in a removable basket, so it can come out before blending and leave a green, pourable soup without cream, flour or potatoes.

A hot zucchini soup with a different aroma
This is a blended vegetable soup served hot, with a gentle onion base and an infusion of star anise. Make it as a first course when zucchini is abundant, or as a light lunch with bread through the rest of the year. The basil at the end is a small finishing garnish.
The recipe comes from my YouTube video, with clearer measurements and an added check on the strength of the anise infusion. I keep the zucchini skins because they contribute color and blend into the soup. The result is different from my cold zucchini soup, which is intended for chilled serving.
I sweat the onions without browning them. A dark onion base would push the flavor toward caramelized sweetness and change the color. Here, the zucchini and anise should remain recognizable. The small amount of olive oil helps cook the onions; there is no butter-and-flour thickener.
My blended leek and potato soup has a different source of body. This version stays lighter and flows easily from the ladle. Do not expect the thick texture of a potato purée.
Ingredients you need
For six starter portions, use 2 lb 3 oz trimmed zucchini, two small onions totaling about 7 oz peeled, one tablespoon olive oil, and 4 1/4 cups low-sodium chicken stock. Keep another 1/2 cup stock available to replace evaporation or loosen the finished soup. Wash the zucchini well and leave the skin on.
The video uses six whole star anise pods. That produces a pronounced infusion, and pod size and freshness make a difference. Keep six for the original version; for a milder variation, begin with one or two. In either case, taste during cooking and remove the basket as soon as the aroma suits you. Do not use ground star anise in the same quantity.
Have 1/2 teaspoon fine salt available, adding only what the stock needs, along with 1/4 teaspoon black pepper. Finish with a few basil leaves if desired. A heavily salted stock can make even that amount of salt unnecessary, so seasoning is a tasting step rather than an automatic addition.
My chicken stock concentrate should be diluted to drinking strength before measuring. For a meat-free variation, use homemade vegetable stock. The chicken-stock version shown in the video is dairy-free, but it is not vegetarian.
Use a heavy pot of about four quarts, a securely closing mesh spice infuser large enough for the pods, a kitchen scale and an immersion blender. A tied cooking sachet suitable for simmering also works. The spice container must keep the hard pods and fragments out of the blended soup.
Step-by-step method
1 Prepare the spice basket
Place the whole star anise in the mesh basket and close it securely. Check the latch before adding it to the pot later. Keep the basket within reach and make sure its chain or handle can be retrieved safely. This small preparation makes removing every pod much easier than searching through hot vegetables.
2 Sweat the onions gently
Peel and finely dice the onions. Heat the olive oil in the pot over medium-low heat, add the onions and cook for about eight to ten minutes, stirring. They should turn translucent and soften without developing brown edges. Lower the heat if the bottom starts catching. Meanwhile, prepare the zucchini.
3 Cut and add the zucchini
Trim the zucchini, then weigh out 2 lb 3 oz. Cut lengthwise into quarters and across into roughly 1/2-inch pieces. Add them to the softened onions and stir to coat. Similar-sized pieces cook evenly and are easier to blend. There is no need to brown or salt-drain the zucchini for this soup.
4 Add stock and infuse
Pour in 4 1/4 cups chicken stock, add pepper and a little of the salt if needed, then immerse the closed spice basket. Bring to a boil and reduce to a steady, gentle simmer. The video cooks the soup uncovered for 45 minutes from boiling. Stir occasionally and add some reserved stock if evaporation becomes excessive.
Taste the liquid after ten to fifteen minutes. Remove the basket early if the anise is already strong enough; the vegetables can continue cooking without it. At the end, the zucchini should collapse easily under a spoon and the onion should be completely soft. A vigorous boil is unnecessary and makes the final thickness harder to control.
5 Remove the pods, blend and serve
Turn off the heat. Lift out the spice basket and check that it is intact before blending. With the blender head fully submerged, blend until smooth, moving carefully through the pot. Stop the motor before lifting the head out of the hot soup. Avoid splashing and keep the pot stable.
The soup should pour in a continuous stream and lightly coat a spoon. If it is thicker than you like, add reserved stock a little at a time. Taste again for salt and pepper, ladle into bowls and add a few basil leaves. Serve promptly while the texture is smooth and the aroma is fresh.
Texture checks and mistakes to avoid
The starting proportion is about one part trimmed zucchini to one part stock by weight, plus onions. It is a useful starting point, not a guarantee of identical thickness: watery zucchini, a wide pot and a strong burner all change the result. Measure the initial stock rather than filling the pot by eye.
Forty-five minutes gives very soft vegetables, although small zucchini pieces may soften sooner. The longer cooking also produces a more muted green than a briefly cooked soup. Adding potatoes or cream to fix that color would change the dish. If the finished soup seems thin, remove the anise and simmer briefly before blending or serving.
The other mistake is trying to correct an overpowering anise flavor with more salt. Remove the spice first. Diluting with an additional batch of unspiced zucchini soup is more effective, but it changes the yield. Taste early enough to avoid needing that correction.
Substitutions
Vegetable stock replaces chicken stock in the same volume. Yellow summer squash can replace zucchini by weight, with a lighter finished color. Yellow onions work in place of white onions. These are variations on the base rather than changes needed to make it function.
For less anise, use one or two whole pods and keep the same tasting check. Omitting the spice makes a plain zucchini soup. Adding cream, cheese or potatoes creates a richer variation; none is required for the original method. For a zucchini dish designed around a creamy finish, try my creamy zucchini gratin.
FAQ
Will it become smooth without potatoes?
Yes. Thoroughly softened zucchini and onions blend into a smooth soup. It will be lighter than a starch-thickened potage. Blend long enough that visible pieces of skin disappear, then judge the consistency before adding extra stock.
Can I use very large garden zucchini?
Yes, but remove any tough skin and large, firm seeds first, then weigh the usable flesh. Mature zucchini can produce a different texture. Small or medium zucchini with tender skins give the closest result to the video.
How should I store and reheat it?
Divide leftovers into shallow containers and refrigerate promptly, within two hours. Use within two to three days or freeze in meal-sized portions. Thaw in the refrigerator and reheat the soup to a rolling boil, stirring well, and at least 165°F. These steps follow Health Canada’s advice for leftovers.
What to serve with it
For a simple lunch, add garlic bread or a raclette grilled cheese. Keep any crunchy topping separate until serving so it does not soften in the bowl.
For other blended vegetable starters, my carrot potage brings a sweeter vegetable flavor, while broccoli soup offers another green option. My leek soup with cheesy croutons is useful when you want a more substantial topping. Find more ideas in the soup recipe collection.
