Understanding the Calorie Count in Onion Soup Mix
When assessing the calorie content of dry onion soup mix, it's crucial to understand that the number is influenced by several factors, including the brand and the serving size. A standard tablespoon of dry mix, often used for dips or as a seasoning, is a common reference point. While the base ingredients—dehydrated onion, salt, and spices—are low in calories, other additions like cornstarch, sugar, and yeast extract can slightly increase the total.
Popular Brands and Their Calorie Content
To give a more specific answer to how many calories are in onion soup mix, let's look at a few well-known products. Comparing these brands highlights the small but notable differences in nutritional values. Remember to always check the most current information on the product packaging, as formulations can change.
- Lipton Onion Soup & Dip Mix: A single tablespoon of this mix contains approximately 20 calories. Its recipe relies on dehydrated onions, salt, and cornstarch, along with flavor enhancers like monosodium glutamate (MSG).
- Knorr Onion Soup Mix: Knorr offers a standard onion mix, with a 14g pouch (which is a larger portion than a tablespoon) containing about 40-45 calories. This variation highlights why checking serving sizes is so important.
- Campbell's Onion Soup Mix: This brand's offering sits at a slightly lower calorie count, with one tablespoon containing around 15 calories.
- Beefy Onion Soup Mix: For varieties that include a beefy flavor, like Lipton's Beefy Onion, the calorie count is often similar or slightly higher, around 25 calories per tablespoon.
The Real Story Behind the Calories
While the calorie count for the dry mix is minimal, the overall calorie intake can increase once you prepare it as a soup or dip. For example, preparing a packet of onion soup mix by adding it to four cups of water, as instructed for soup, results in a very low-calorie broth. However, turning it into a French onion dip by combining the mix with sour cream will dramatically increase the final dish's caloric value. A single cup of sour cream, for instance, adds hundreds of calories to the final product.
High Sodium Content: A Major Nutritional Consideration
Beyond calories, the most significant nutritional concern with most pre-packaged onion soup mixes is the high sodium content. The salt is a primary ingredient and flavor enhancer, leading to surprisingly high levels for such a small serving size. A single tablespoon can contain between 540 and 640 mg of sodium, which is a substantial portion of the recommended daily intake. This is particularly important for individuals monitoring their blood pressure or those on a low-sodium diet.
Common Ingredients in Store-Bought Onion Soup Mix:
- Dehydrated Onions
- Salt
- Cornstarch or Maltodextrin
- Sugar
- Yeast Extract
- Caramel Color
- Flavor Enhancers (MSG, Disodium Guanylate)
The Homemade Alternative: Control Your Ingredients and Calories
For those who prefer a healthier option or need to control specific ingredients, making your own onion soup mix is an excellent alternative. A DIY version eliminates processed ingredients, hidden sugars, and allows you to reduce or remove salt entirely. The calorie count for a homemade mix is typically low, derived mainly from dehydrated onion flakes and a small amount of herbs. For example, a gluten-free and vegan homemade mix recipe found online reports just 22.7 calories per packet equivalent, with significantly lower sodium.
Comparison: Store-Bought vs. Homemade Onion Soup Mix
| Feature | Store-Bought Mix (e.g., Lipton) | Homemade Mix (Standard Recipe) |
|---|---|---|
| Calories (per 1 tbsp) | Approx. 20-25 | Approx. 15-20 |
| Sodium (per 1 tbsp) | 540-640mg+ | Customizable (Can be very low) |
| Ingredients | Dehydrated onions, salt, cornstarch, sugar, MSG, caramel color | Dehydrated onions, onion powder, salt, garlic powder, parsley, black pepper |
| Dietary Restrictions | May contain gluten, dairy, or MSG. High sodium. | Easily made gluten-free, low-sodium, and additive-free. |
| Cost | Relatively inexpensive per packet | Slightly more expensive upfront for ingredients, but cheaper per serving long-term |
Conclusion: A Calorie-Conscious Approach
While the number of calories in onion soup mix is low on its own, it is a high-sodium product that requires careful consideration for dietary planning. For most people, a single serving of the dry mix won't have a significant impact on daily calorie intake, but its primary nutritional concern is the sodium content. Choosing a homemade recipe is a simple way to enjoy the classic flavor while having complete control over the ingredients and overall health profile. Whether you opt for a store-bought version or a DIY blend, being mindful of the serving size and how you prepare it will ensure you can enjoy this versatile seasoning mix responsibly.

Frequently Asked Questions
What is the main source of calories in onion soup mix? The primary source of calories in dry onion soup mix comes from carbohydrates, including starches and sugars like cornstarch, maltodextrin, and simple sugars added for flavor and texture.
Is onion soup mix good for weight loss? While the mix itself is low in calories, its high sodium content can cause water retention. When prepared as a simple broth, it can be a low-calorie addition to a diet, but it should be consumed in moderation due to sodium levels.
How does preparing the mix affect the calorie count? Preparation significantly affects the calorie count. Adding the dry mix to water for soup adds very few calories, but mixing it with high-fat ingredients like sour cream for a dip will drastically increase the overall caloric value.
Is homemade onion soup mix healthier than store-bought? Yes, a homemade mix is generally healthier because you can control the amount of salt and avoid artificial additives like MSG, caramel coloring, and preservatives that are often found in commercial versions.
Does onion soup mix contain MSG? Many conventional brands of onion soup mix contain MSG (monosodium glutamate) as a flavor enhancer. If you have a sensitivity to MSG, it's best to check the ingredients list or choose a homemade or explicitly MSG-free brand.
Can people on a gluten-free diet use onion soup mix? Not all onion soup mixes are gluten-free. Some brands contain wheat-based ingredients like wheat flour or wheat-derived flavorings. It is important to read the ingredients list carefully and look for certified gluten-free products.
Why is the sodium content so high in onion soup mix? Salt is a critical component in dry mixes, acting as both a primary seasoning and a preservative. The high concentration of salt is what gives the mix its robust, savory flavor, which is a characteristic of most commercial bouillon and soup mixes.
