What You'll Learn

Tomatoes are keto-friendly
When it comes to making keto-friendly tomato soup, there are a few things to keep in mind. Firstly, it's important to avoid store-bought sauces, as these often contain added sugar and long ingredient lists that are less than ideal for keto. Instead, it's best to make your own sauce using fresh or canned tomatoes, butter, onion, garlic, and chicken or vegetable broth. You can also add heavy cream or coconut cream for a dairy-free option, as well as spices and herbs like basil to taste.
Another option for a quick and easy keto tomato soup is to use a jar of sugar-free marinara sauce as a base. This method requires fewer ingredients and no blender, and you can add heavy whipping cream, sweetener, chicken broth, and tomato paste to taste. This soup can be made in just 15 minutes and is a great option for those on a keto diet who are craving a comforting bowl of tomato soup.
Some people may be concerned about the carb count in tomatoes and whether they are truly keto-friendly. While it's true that tomatoes have a slightly higher carb count than other produce, with about 3.9g of total carbs per 100g of tomato, they can still be enjoyed on a keto diet if you plan out your macros. In fact, there are many recipes available for keto tomato soup, and it can be a delicious and healthy option for those following a low-carb diet.
Overall, tomatoes are a keto-friendly food that can be enjoyed in moderation as part of a ketogenic diet. They are a good source of antioxidants and can be used to make a variety of keto-friendly dishes, including a comforting and creamy tomato soup.

Keto tomato soup toppings
While it is possible to eat tomato soup on a keto diet, it is important to be mindful of the toppings and sides you choose. Here are some keto-friendly topping ideas to elevate your tomato soup:
Shredded Cheese
Adding shredded cheese, such as sharp cheddar or Parmesan, can enhance the flavour and creaminess of the soup.
Fresh Herbs
Chopped fresh herbs like basil, parsley, thyme, or oregano can add a burst of flavour and a touch of colour to your soup.
Spices
If you prefer your soup on the spicier side, consider adding red pepper flakes, cayenne pepper, or Italian seasoning. These spices will give your soup a kick and may help boost your metabolism.
Nuts and Seeds
For a crunchy texture and extra nutrients, try topping your soup with chopped nuts or seeds, such as toasted almond slivers or pumpkin seeds.
Cream or Milk
To make your soup even creamier and richer, swirl in some heavy cream, coconut cream, full-fat coconut milk, or even almond milk. This will also help to make the soup more filling and satisfying.
Protein
For a heartier meal, consider adding some protein to your soup, such as cooked shrimp, chicken, or bacon bits. This will not only boost the flavour but also provide you with a more well-rounded meal.
Remember to choose toppings that align with your keto diet and always check the nutritional information of any pre-made toppings or ingredients to ensure they fit within your macros. Enjoy experimenting with different combinations to find your perfect keto-friendly tomato soup!

Tomato soup with keto grilled cheese
Yes, you can eat tomato soup on a keto diet! Here is a recipe for a comforting and delicious tomato soup with keto grilled cheese. This recipe serves one, but you can easily scale it up to serve more.
Ingredients:
- Butter
- 1/2 onion, finely chopped
- 1 garlic clove, crushed
- 1 can of whole tomatoes
- 1 cup of chicken stock
- 1/2 tsp tomato bouillon (optional)
- 1/4 cup of heavy cream
- Salt and pepper, to taste
- Fresh basil, to serve (optional)
- Sour cream, to serve (optional)
For the keto grilled cheese:
- 2 tbsp shredded parmesan cheese
- 2 slices of keto-friendly bread
- 2 slices of cheese of your choice (e.g. cheddar, American, gruyere, or halloumi)
Method:
First, make the soup. Melt some butter in a large saucepan over medium heat. Add the onion and cook for about 5 minutes, until translucent. Then, add the garlic and cook for another 30 seconds. Next, add the canned tomatoes, chicken stock, and tomato bouillon (if using). Increase the heat and bring the mixture to a boil. Reduce the heat and let the soup simmer for 10-15 minutes.
Once the soup has simmered, remove it from the heat and carefully blend it until smooth and creamy. Return the soup to the stove and stir in the heavy cream. Season with salt and pepper, to taste.
While the soup is simmering, prepare the keto grilled cheese. Sprinkle the parmesan cheese onto a chaffle iron or waffle maker, then pour in the batter for your keto bread (you can use a basic chaffle bread batter). Sprinkle a little more parmesan cheese on top and cook until crispy and golden brown.
Once the bread is cooked, assemble the grilled cheese sandwich by placing the cheese slices between the two slices of bread. Pop the sandwich into a hot oven or toaster oven for a couple of minutes, until the cheese is melted.
Serve the soup with a dollop of sour cream and some fresh basil, if desired. Enjoy the grilled cheese sandwich on the side, or dunk it into the soup!
Tips and Variations:
- If you don't have canned whole tomatoes, you can use a jar of sugar-free marinara sauce as a base for your soup.
- For a dairy-free option, replace the heavy cream with coconut cream or full-fat coconut milk.
- If you don't have a chaffle iron or waffle maker, you can use a grill pan or panini maker to make the grilled cheese.
- Get creative with your grilled cheese fillings! Try mixing different cheeses, like gruyere and cheddar, or using halloumi for a bread-free option.
- For a complete meal, serve the soup with a side salad and some low-carb garlic bread.

Storing keto tomato soup
If you want to store your keto tomato soup for a longer period, freezing is an option. However, it is recommended to freeze the soup without adding the cream, as cream and tomatoes can react unpredictably when frozen together. The soup can be frozen for up to three months.
When storing keto tomato soup, it is important to use airtight containers to prevent the soup from absorbing other odours in the fridge or freezer. Additionally, clearly label the storage container with the date and contents to ensure you consume the soup while it is still fresh and at its best quality.
By following these simple storage instructions, you can enjoy your keto tomato soup multiple times and make the most of your delicious creation!
