The ketogenic diet, often referred to as “keto,” has gained immense popularity for its potential benefits in weight management and overall health. This high-fat, moderate-protein, and very low-carbohydrate diet forces the body to switch its primary fuel source from glucose (from carbohydrates) to ketones (from fat). While the keto diet boasts a variety of satisfying meals, navigating the soup aisle can be tricky. Many commercially available soups are loaded with hidden carbohydrates, starches, and sugars, making them unsuitable for a ketogenic lifestyle. But fear not! Soup can absolutely be a delicious and nutritious part of your keto diet. The key is choosing the right ingredients and understanding the carbohydrate content.
Understanding Carbohydrates in Soup
Before diving into specific soup options, it’s crucial to understand why carbohydrate awareness is so important on keto. The primary goal of the ketogenic diet is to induce and maintain a state of ketosis, where your body efficiently burns fat for energy. Consuming too many carbohydrates can quickly kick you out of ketosis, hindering your progress.
Soup, in particular, can be a sneaky source of hidden carbs. Common culprits include:
- Starchy Vegetables: Potatoes, corn, peas, and carrots (in large quantities) can significantly increase the carbohydrate content of a soup.
- Thickeners: Flour, cornstarch, and rice flour are often used to thicken soups, adding a substantial amount of carbohydrates.
- Legumes: Beans and lentils are high in carbohydrates and are generally avoided on a strict keto diet.
- Sugars: Some canned or pre-packaged soups contain added sugars for flavor, which should be avoided.
- Pasta and Rice: Noodle soups and rice-based soups are definitely not keto-friendly.
Therefore, careful attention must be paid to the ingredients and nutritional information of any soup you consider eating on keto.
Keto-Friendly Soup Ingredients
The good news is that many delicious and nutritious ingredients are perfectly acceptable (and even encouraged) on the keto diet. These ingredients can form the base of flavorful and satisfying keto soups.
- Broth: Bone broth, chicken broth, beef broth, and vegetable broth are excellent low-carb bases for soup. Choose unsweetened varieties with no added starch.
- Healthy Fats: Coconut milk, heavy cream, olive oil, and avocado oil add richness, flavor, and healthy fats to your soup, contributing to your daily fat intake.
- Non-Starchy Vegetables: Spinach, kale, zucchini, cauliflower, broccoli, mushrooms, celery, and bell peppers are all low-carb and packed with nutrients.
- Protein: Chicken, beef, fish, shrimp, and pork are excellent sources of protein for keto soups. Cooked shredded chicken or ground beef are particularly versatile.
- Herbs and Spices: Herbs and spices are your best friends on keto! They add flavor and complexity to your soup without adding carbohydrates. Experiment with garlic, onion powder, paprika, chili powder, cumin, thyme, rosemary, and oregano.
- Cheese: Adding cheese, such as cheddar, mozzarella, or parmesan, can add flavor and texture to your keto soup.

Tips for Making Keto Soup
Here are some additional tips to ensure your soup is keto-compliant and delicious:
- Read Labels Carefully: Always check the nutritional information and ingredient list of any broth, canned vegetables, or pre-packaged ingredients to ensure they are low in carbohydrates and free of added sugars.
- Control Portions: Even keto-friendly soups can contribute to your daily carbohydrate intake, so be mindful of portion sizes.
- Use Healthy Fats Generously: Don’t be afraid to add healthy fats like coconut milk, heavy cream, or olive oil to your soup. These fats will help you feel full and satisfied.
- Experiment with Flavors: Keto doesn’t have to be boring! Experiment with different herbs, spices, and flavor combinations to create soups that you truly enjoy.
- Make Ahead: Soup is a great make-ahead meal. Prepare a large batch on the weekend and enjoy it throughout the week.
- Add Protein: Ensure you’re getting enough protein by including sources like shredded chicken, ground beef, or seafood in your soup.
- Consider using an immersion blender: An immersion blender can be useful for making creamy soups without adding high-carb thickeners.
- Use xanthan gum sparingly: If you need to thicken your soup, use xanthan gum sparingly. Start with a very small amount (1/4 teaspoon) and add more as needed.
Pre-Made Keto Soup Options
While making soup from scratch is often the best option for controlling ingredients and ensuring keto-friendliness, there are some pre-made options available. However, it’s essential to be extra diligent when selecting pre-made soups.
What to look for in pre-made keto soup:
- Low Carbohydrate Count: Check the nutrition label carefully to ensure the soup is low in net carbohydrates (total carbohydrates minus fiber). Aim for soups with less than 10 grams of net carbs per serving, and ideally closer to 5 grams.
- No Added Sugar: Avoid soups with added sugars, such as corn syrup, dextrose, or sucrose.
- No Starch: Steer clear of soups that contain starch as a thickener, such as cornstarch, potato starch, or tapioca starch.
- Healthy Ingredients: Look for soups that are made with real, whole ingredients, such as broth, vegetables, and protein.
- High-Fat Content: Ideally, the soup should have a decent amount of healthy fats, which will help you feel full and satisfied.
Some brands that offer keto-friendly soup options (always double-check the labels as formulations can change) include:
- Progressive Light: Certain varieties may be lower in carbs.
- Pacific Foods: Some of their organic broths and soups can be keto-friendly.
However, even these options might require modification, such as adding extra fat (e.g., coconut oil or avocado oil) or protein. Reading reviews from other keto dieters can also be helpful in identifying suitable pre-made soups.
In conclusion, soup can be a delicious and satisfying part of a ketogenic diet. By focusing on low-carbohydrate ingredients, healthy fats, and flavorful seasonings, you can create a wide variety of keto-friendly soups that will help you stay on track with your goals. Whether you prefer creamy soups, hearty chilis, or flavorful broths, there’s a keto soup out there for everyone. Remember to always read labels carefully and adjust recipes to suit your personal preferences and macronutrient needs. Enjoy!
What makes a soup keto-friendly?
A keto-friendly soup is one that is low in carbohydrates and high in healthy fats. It typically avoids ingredients like pasta, rice, potatoes, and sugary vegetables like corn or carrots in large quantities. The focus is on utilizing non-starchy vegetables such as spinach, cauliflower, zucchini, and broccoli, along with a rich broth, protein sources like meat or tofu, and healthy fats such as avocado oil, coconut milk, or butter.
The carbohydrate count per serving should be minimal, ideally staying below 10 grams net carbs. This allows you to enjoy the soup while maintaining ketosis, which is the metabolic state where your body primarily burns fat for fuel. Careful attention to ingredient selection and portion size is crucial for ensuring your soup aligns with your ketogenic goals.
Which are the best vegetables to include in a keto soup?
The best vegetables for keto soups are those low in carbohydrates and high in fiber and nutrients. Leafy greens like spinach, kale, and collard greens are excellent choices. Cruciferous vegetables such as broccoli, cauliflower, and cabbage provide substantial volume and nutritional benefits without significantly impacting carb counts. Zucchini and asparagus are also great options, offering a mild flavor that complements a variety of soup bases.
Other suitable vegetables include bell peppers (in moderation), mushrooms, and celery. Remember to avoid or limit high-carb vegetables like potatoes, corn, and carrots. Prioritize non-starchy options to create a satisfying and keto-compliant soup. Utilizing these vegetables ensures you enjoy a nutrient-rich and flavorful soup without exceeding your daily carbohydrate limits.
Can I use canned soup on keto, and if so, what should I look for?
While convenient, most commercially canned soups are not keto-friendly due to added sugars, starches, and high-carb vegetables. However, you can find some suitable options if you read the labels carefully. Look for soups that are specifically marketed as “low-carb” or “keto-friendly.” Pay close attention to the nutrition facts panel, particularly the carbohydrate count, fiber content, and sugar content. The net carbs (total carbs minus fiber) should ideally be under 10 grams per serving.
Avoid soups with added sugars, cornstarch, rice, pasta, or large amounts of potatoes or carrots. Check the ingredient list for hidden sources of carbohydrates, such as modified food starch or dextrose. It’s often a better approach to make your own keto soup, as this allows you to control the ingredients and ensure they align with your dietary needs. When choosing canned, prioritize brands with minimal ingredients and a focus on whole, unprocessed foods.
What are some good protein sources for keto soup?
Excellent protein sources for keto soup include meats such as chicken, beef, pork, and fish. These provide a significant amount of protein without adding carbohydrates. Cooked meats can be added directly to the soup or used to create a flavorful broth. For vegetarian options, consider using tofu or tempeh, both of which are relatively low in carbohydrates and high in protein.
Bone broth is another fantastic protein-rich addition, providing collagen and essential amino acids. Eggs, hard-boiled or poached, can also be incorporated for an extra protein boost. Select protein sources that complement the flavors of your soup and help to keep you feeling full and satisfied while staying within your keto macronutrient targets.
How can I thicken keto soup without using flour or cornstarch?
There are several effective ways to thicken keto soup without using traditional high-carb thickeners like flour or cornstarch. Pureed vegetables, such as cauliflower, butternut squash (in moderation), or zucchini, can add creaminess and thickness while remaining low in carbohydrates. Simply blend a portion of the soup before serving to achieve the desired consistency. Heavy cream or coconut cream are also excellent options, providing richness and thickening the soup as they simmer.
Another technique is to use xanthan gum, a small amount of which can dramatically thicken liquids. Be cautious when using xanthan gum, as too much can result in a slimy texture. Start with a very small amount (about 1/8 teaspoon per serving) and gradually add more until you reach the desired thickness. Cheese, such as cream cheese or shredded cheddar, can also be melted into the soup to add flavor and thickness. Gelatin is also an option, added slowly as the soup simmers.
Can I add dairy to my keto soup, and what types are best?
Dairy can be a great addition to keto soup, adding richness and flavor. However, it’s important to choose the right types. High-fat dairy options like heavy cream, sour cream, and full-fat cream cheese are excellent choices. These are low in carbohydrates and provide healthy fats that are beneficial for maintaining ketosis. Cheese, such as cheddar, mozzarella, and parmesan, can also be added for flavor and thickening, but be mindful of the carbohydrate content.
Avoid using low-fat or skim milk, as these tend to be higher in carbohydrates. Greek yogurt can be used in moderation, but choose the full-fat, plain variety and be aware of its carbohydrate count. Coconut milk, especially the full-fat canned variety, is a non-dairy alternative that adds a creamy texture and rich flavor to soups. Ensure to always check nutrition labels and adjust portion sizes accordingly to fit your macro goals.
How do I calculate the net carbs in my homemade keto soup?
Calculating the net carbs in your homemade keto soup is essential for staying within your daily carbohydrate limit. Start by recording the total carbohydrates and fiber content of each ingredient you use. This information can usually be found on the nutrition labels of packaged foods or through online nutritional databases for fresh produce. Add up the total carbohydrates and total fiber for all ingredients in the recipe.
To calculate the net carbs for the entire batch of soup, subtract the total fiber from the total carbohydrates. Then, divide the net carbs by the number of servings in the recipe to determine the net carbs per serving. This will give you a clear understanding of how the soup fits into your daily macros. Using tracking apps like MyFitnessPal or Cronometer can simplify this process by automatically calculating net carbs based on the ingredients you input.
