Chef's note
Feel free to customize this soup to your liking by adding fresh oregano or a sprinkle of Parmesan for extra flavor. For a dairy-free option, swap the heavy cream with coconut cream. To enhance the sweetness of the tomatoes, choose ripe plum or Roma tomatoes, or use a canned, no-sugar-added tomato sauce for a shortcut.

How to Make Keto Tomato Soup: Step-by-Step Guide
Cooking methods
Preparation steps
- Wash and chop the tomatoes, mince the garlic, and chop the onion.
- Measure out the broth, cream, and tomato paste.
Cooking instructions
- Heat the olive oil in a large pot over medium heat. Add the onion and sauté until softened, about 3-4 minutes.
- Add the garlic and cook for another 30 seconds until fragrant.
- Stir in the chopped tomatoes and tomato paste, and cook for 5 minutes, stirring occasionally.
- Pour in the broth and bring the mixture to a simmer. Add the dried basil, salt, and pepper to taste.
- Simmer for 10 minutes, allowing the flavors to blend.
- Remove the soup from heat and use an immersion blender to puree it until smooth. If using a standard blender, blend the soup in small batches, being careful not to overfill.
- Stir in the heavy cream and adjust the seasoning. If you like a bit of spice, add the red pepper flakes.
- Return the soup to low heat for 1-2 minutes, then serve hot.
Chef's pro tip
For an extra smooth and creamy texture, strain the soup through a fine mesh sieve after blending. This removes any seeds or bits of skin, giving you that classic silky tomato soup texture. To thicken the soup, let it reduce on the stove or blend in some cheese—it also doubles as a rich, creamy tomato pasta sauce.
What to Serve with Tomato Soup?
How to make it healthier
For a lighter version, you can replace the heavy cream with unsweetened almond milk to reduce the fat and calorie content, though the soup will be less creamy. You can also add more vegetables like zucchini or cauliflower to boost the fiber and nutrition without adding carbs.
Time-saving tips
Use canned, no-sugar-added tomatoes and pre-chopped onions and garlic to save time on prep. This will cut the total cooking time to just 15 minutes.
What can I prepare ahead of time?
You can chop the onions, garlic, and tomatoes in advance and store them in the fridge. You can also make the soup up to 2 days ahead and reheat it when ready to serve.
Storage and reheating instructions
Storage instructions
Store leftover soup in an airtight container in the fridge for up to 5 days. You can also freeze the soup for up to 3 months in a freezer-safe container.
Reheating best practices
To reheat, pour the soup into a saucepan and warm over low heat, stirring occasionally. If reheating from frozen, let it thaw in the fridge overnight before reheating on the stove. Add a splash of broth or cream if the soup has thickened too much.
