The word “soup” covers a wider calorie range than any other category on the site. Miso soup is about 80 calories per bowl; French onion soup with its bread-and-cheese topping is about 480 — six times as much, under the same word and in the same serving bowl. The assumption that “soup is a light dish” is right about half the time, and this category shows exactly where it breaks down.
Each of the ten pages here has a full recipe for a defined number of servings, a note on the step that determines the result, and a nutrition table per bowl — not per 100 grams, which is a meaningless measure for a liquid dish.
What really determines how many calories are in a bowl of soup
- The fat that goes in at the start, not the vegetables. A kilo and a half of vegetables in a vegetable soup is about 500 calories; three tablespoons of olive oil poured into the bottom of the pot are about 360 more. In two of the ten pureed soups here, fat is more than half the calories.
- What comes with the soup is often bigger than the soup. A slice of bread with cheese, soup croutons, crisp soup “almonds” or a swirl of cream add 100-270 calories per bowl. In French onion soup the topping is about 270 of the 480 — more than half the serving.
- Pureed isn’t necessarily thick, and thick isn’t necessarily fatty. Pumpkin soup gets its thickness from legumes and starchy vegetables just as much as from cream. The thickness of split pea soup comes entirely from the legume, without a drop of cream.
- Legume soup is a meal; broth soup is a starter. The difference isn’t in flavor but in protein and fiber. A bowl of split pea soup carries about 14 grams of protein and about 15 grams of fiber; a bowl of tomato soup carries 3 grams of protein. Both are legitimate — but only one of them keeps you full until the next meal.
- Sodium is the number that isn’t written in the table. Soup is one of the biggest sources of sodium in the diet, and this is especially true of miso and tom yum, which are built on fermented soybean paste and fish sauce. Details on the nutrient itself on the sodium page.

| Chicken soup | Chicken broth with vegetables | about 190 per bowl (350 ml) with meat |
| Vegetable soup | Homemade vegetable soup | about 150 per bowl (350 ml) |
| Split pea soup | Legume soup | about 240 per bowl (350 ml) |

| Mushroom soup | Cream soup | about 200 per bowl (300 ml) |
| French onion soup | Soup with a bread-and-cheese topping | about 480 per bowl (300 ml, with the topping) |
| Minestrone | Italian vegetable and bean soup | about 210 per bowl (350 ml) |
| Tomato soup | Pureed soup | about 185 per bowl (300 ml) |
| Miso soup | Clear Japanese soup | about 80 per bowl (200 ml) |
| Tom yum goong | Thai hot-and-sour soup | about 160 per bowl (350 ml) |
Four families, and the logic of each
Broth soups. Chicken soup is the clear representative: the flavor is built by slow extraction from bones and vegetables, not by frying. The one rule that matters here is that the soup must not boil — a rolling boil breaks down fat and smashes protein particles into the liquid, and the soup comes out cloudy. The same logic applies to bone broth on its own.
Pureed soups. Pumpkin, mushroom and tomato are built on the same method: extract flavor by caramelizing or roasting, cook, and blend. This is also where the category’s big calorie trap lies — cream goes in at the end, when you no longer taste it separately, and doubles the calorie count without changing the serving size.
Legume soups. Split pea and minestrone are the only ones in the category you can eat as a whole meal. They provide plant protein, fiber and potassium at a low calorie cost, and the same idea recurs in Turkish lentil soup and Moroccan harira.
Clear Asian soups. Miso and tom yum are built on flavor rather than body: fermented soybean paste, lemongrass and galangal, lime and chili. Both are genuinely low in calories — and genuinely high in sodium. That’s the deal worth knowing before calling them “diet soups.”
Five rules that improve every soup on this page
- Caramelize before adding liquid. Onions, roots and mushrooms that have been roasted or browned in a pan give a depth you can’t get by cooking in water. In French onion soup that’s 45 minutes of work, and it’s the whole soup.
- Salt at the end, not the beginning. Soup reduces, and salt doesn’t evaporate with it. Whoever salts at the start of an hour of cooking almost always ends up with soup that’s too salty.
- Acid to finish. A few drops of lemon or vinegar at the end of cooking sharpen a soup that tastes “flat” — usually that’s the real problem when you feel like adding more salt.
- Blend hot, add boiling liquid. Soup keeps thickening as it cools and when reheated. Cold water poured into a boiling pot stops the cooking and dilutes the flavor too.
- Soup always tastes better on the second day. Most of the soups here keep 4-5 days in the fridge, and most freeze well. The exceptions are soups with cream and soups with noodles, both of which fall apart when thawed.
Homemade soup vs. powdered soup
The difference between the two isn’t just in flavor. Industrial soup powder is built on salt, flavor enhancers and hydrogenated or refined vegetable fat, and mainly supplies sodium — usually 800-1,200 mg per cup, which is about half the recommended daily limit in one bowl. More on the instant soup page and the ultra-processed foods page.
Homemade soup, on the other hand, supplies what the vegetables and legumes themselves carry: potassium, fiber, vitamin A from carrots and pumpkin, and plant iron from the legumes — whose absorption improves when you finish the bowl with a squeeze of lemon. That is the practical difference, and it is much bigger than the difference in taste.

Frequently asked questions
Question: Which soup is lowest in calories? Answer: Of the ten here, miso soup — about 80 calories per 200 ml bowl. After it comes tom yum at about 160 calories, which also provides about 24 grams of protein from the shrimp. For both, the caveat isn’t calories but sodium: one bowl carries 700-1,200 mg of sodium.
Question: Does soup really help you lose weight? Answer: Not on its own, but it helps through two proven mechanisms. Hot liquid fills volume in the stomach and slows the pace of eating, and a serving of soup before a meal reduces the amount eaten afterward. The condition is that the soup itself isn’t loaded with cream and bread — otherwise it adds calories instead of replacing them.
Question: How long does soup keep in the fridge? Answer: 4-5 days for vegetable and legume soups, and 3-4 days for chicken or meat broth soups. Cream-based soups keep only 2-3 days. Rapid cooling matters: it’s best to transfer the soup to a shallow container and chill it within two hours, rather than leaving a hot pot on the counter overnight.
Question: Which soups can you freeze? Answer: Almost all of them, with two exceptions. Soups with cream or milk tend to separate when thawed, and soups with noodles or rice fall apart completely — freeze these without the carbohydrate and add it fresh when reheating. The usual freezer storage time is 3 months.
Question: Why does my soup come out cloudy? Answer: Almost always because of a rolling boil instead of a gentle simmer. A hard boil breaks down fat and disperses protein particles in the liquid, and that’s what makes it cloudy. The fix is to start with cold water, skim off the foam in the first ten minutes and keep the heat low throughout cooking — details in chicken soup.
Question: What is the difference between soup and broth? Answer: Broth (broth or stock) is the liquid itself, cooked for hours from bones and vegetables and strained — it’s an ingredient, not a dish. Soup is the finished dish, built on broth or water and containing the solids as well. Details on the broth itself on the bone broth page.
