While often perceived as a light and healthy meal, some soups can contain a substantial number of calories. The primary reason why is soup so high in calories boils down to its ingredients and preparation method, not the broth itself. Rich, heavy additives designed to enhance flavor and texture are the main culprits, drastically increasing the energy density of the dish.
The Culprits: High-Calorie Ingredients in Soup
- Cream and Dairy Products: Heavy cream, whole milk, sour cream, and cream cheese are foundational to many popular creamy soups like chowders and bisques. While they provide a rich, velvety texture, they also pack a significant amount of saturated fat and calories. Even a small amount can significantly increase the calorie count of a serving.
- Fats and Oils: Sautéing aromatics like onions and garlic in large amounts of butter or oil before adding other ingredients contributes to the overall calorie load. While fat is essential for flavor, excessive use adds calories without substantial nutritional benefit.
- Starchy Thickeners: To achieve a thick consistency, many soup recipes rely on high-starch ingredients. A roux, made from butter and flour, is a classic thickener that is calorie-dense. Other starchy vegetables, like potatoes and corn, or added grains such as rice and pasta, also contribute a significant amount of carbohydrates and calories.
- Cheese: For a savory, rich flavor, cheese is often added to soups, particularly varieties like broccoli cheddar and loaded potato soup. Cheese is a high-calorie ingredient, and adding it generously can make a soup as calorie-dense as a full meal.
- Protein Sources: While protein is important for satiety, certain high-fat protein sources, such as fatty ground beef, bacon, or certain sausages, will add more calories and fat to a soup than leaner options like chicken breast or lentils.
- Toppings: The final toppings can also increase calories. Croutons, tortilla strips, crispy fried onions, or extra cheese can push the calorie count higher, transforming a simple soup into a heavier dish.
Low-Calorie vs. High-Calorie Soups: A Comparison
| Feature | Low-Calorie Soups | High-Calorie Soups | 
|---|---|---|
| Base | Broth (vegetable, chicken, beef) | Cream or milk-based | 
| Thickening | Pureed vegetables, legumes | Roux (butter and flour), heavy cream, cheese | 
| Ingredients | Vegetables, lean protein, legumes, herbs | Fatty meats, starchy vegetables, cheese, pasta | 
| Fat Content | Low, from minimal added oil | High, from butter, cream, and cheese | 
| Calorie Density | Low, high in water and fiber | High, rich in dense fats and starches | 
| Satiety | High, due to volume and fiber | High, due to fat and richness | 
The Difference Between High and Low-Calorie Soups
To understand the vast difference in calorie content, consider the contrast between a simple vegetable soup and a rich, creamy potato and leek soup. The vegetable soup relies on a water-based broth, lean vegetables, and herbs for its flavor profile. Its high water and fiber content make it filling but low in calories. The creamy potato soup, however, builds its flavor and texture from a base of butter, cream, and starchy potatoes, leading to a much higher-calorie outcome per serving. The base liquid is the most significant determinant of a soup's overall calorie count. Soups made with rich, high-fat liquids are far more calorie-dense than those built on water or low-calorie broths.
How to Reduce Soup Calories
Creating a lower-calorie soup doesn't mean sacrificing flavor. Here are some tips to make your soups healthier:
- Choose a Broth Base: Opt for vegetable, chicken, or beef broth instead of a cream or cheese base.
- Thicken with Lighter Alternatives: Instead of heavy cream or a roux, try pureeing a portion of the soup's vegetables or adding mashed legumes like lentils or chickpeas for a creamy consistency.
- Add Fiber-Rich Ingredients: Incorporate high-fiber vegetables like beans, lentils, broccoli, and cabbage to increase volume and satiety without a high-calorie cost.
- Use Lean Protein: Use lean cuts of chicken breast, turkey, or fish, or plant-based proteins like lentils and beans, to boost protein content with fewer calories and less fat.
- Manage Fats and Oils: Use just enough oil to sauté vegetables to prevent sticking, and drain any excess fat from cooked meat before adding it to the soup.
- Flavor with Herbs and Spices: Enhance flavor with herbs like basil, oregano, and thyme, or spices like garlic powder, ginger, and cumin, rather than relying on high-calorie fats.
- Mind Your Toppings: Garnish with fresh herbs, a sprinkle of nutritional yeast, or a dollop of low-fat yogurt instead of high-calorie options.
Canned vs. Homemade Soup
Canned soups offer convenience but are often high in calories, sodium, and preservatives. Making soup from scratch gives you complete control over the ingredients, allowing you to use fresh vegetables, lean proteins, and less salt and fat. This can lead to a more nutritious and lower-calorie meal overall. For instance, a homemade tomato soup from fresh ingredients is significantly more nutrient-dense and lower in added fats and sugars than many store-bought varieties.

Conclusion
While some soups are known for being low-calorie and healthy, the high-calorie reputation of others is well-earned, stemming from specific, energy-dense ingredients. Cream, high-fat dairy, starchy thickeners, and excessive fats are the primary reasons why is soup so high in calories in certain recipes. By understanding and controlling these factors, you can enjoy a delicious, satisfying, and nourishing bowl of soup without worrying about its impact on your calorie intake.
