My recipe for gluten-free tomato soup is incredibly simple to prepare and captures the authentic taste of Campbell’s Tomato Soup. With just a handful of uncomplicated ingredients, you can savour homemade gluten-free tomato soup in just 20 minutes!
One of the cherished soups from my childhood is Campbell’s Tomato Soup. Regrettably, Campbell’s Tomato Soup contains gluten. This led me to create my own effortlessly uncomplicated tomato soup recipe. There’s no need for any unusual ingredients or a blender.

How to Prepare Gluten-Free Tomato Soup
Begin by pouring the tomato puree, sauce, tomato paste, and chicken broth into a large pot. Stir them together thoroughly and cook over medium heat.
In a measuring cup or a small bowl, whisk together the milk and gluten-free flour until they are fully combined. Pour this milk mixture into the tomato mixture and stir everything together until fully blended.
Next, introduce the salt, garlic powder, onion powder, and brown sugar to the soup and stir until they are well combined. Allow the soup to cook over medium heat for 10-15 minutes or until it thickens.
Serve the soup while warm and savour the delicious flavours!
For any leftovers, store them in an airtight container in the refrigerator. When reheating, you can use the microwave or stovetop.
Tips Of Recipe
- Read the Recipe First: Always read through the entire recipe before you start cooking. This will give you an overview of the steps involved and ensure you have all the necessary ingredients.
- Gather Ingredients and Equipment: Before you begin, gather all the ingredients and equipment you’ll need. This will save you time and make the cooking process smoother.
- Preparation is Key: Chop, dice, and measure out all your ingredients before you start cooking. This is known as “mise en place” and it helps you stay organised and focused.
- Follow Cooking Techniques: Pay attention to cooking techniques like chopping, sautéing, simmering, etc. These techniques can greatly impact the flavour and texture of your dish.
- Adjust Seasoning Gradually: It’s easier to add more seasoning later than to fix an over-seasoned dish. Taste as you go and adjust the seasoning gradually.
- Don’t Rush: Cooking often requires patience. Allow ingredients to cook properly and develop their flavours.
- Use Fresh Ingredients: Whenever possible, use fresh, high-quality ingredients. They tend to provide better flavour and texture to your dishes.
- Balance Flavours: Try to balance the flavours in your dish. For example, if something is too acidic, you can add a little sweetness to balance it out.
- Experiment and Have Fun: Don’t be afraid to get creative and try new things. Cooking is an art as much as it is a science.
- Clean as You Go: Wash dishes and utensils as you cook to keep your workspace organized. It makes the cleanup process much easier.

Frequently Asked Questions
- What is the difference between baking powder and baking soda?
- Baking powder is a combination of an acid and a base, while baking soda is a base. They are both leavening agents used in baking, but baking powder is typically used in recipes that do not contain acidic ingredients, whereas baking soda requires an acidic component to activate.
- How can I substitute eggs in a recipe for a vegan or allergy-friendly option?
- Common egg substitutes include mashed bananas, applesauce, silken tofu, yoghurt, or commercial egg replacers. Each option may affect the texture and flavour of the final dish, so it’s best to choose based on the specific recipe.
- What is the difference between broth and stock?
- Broth is typically made by simmering meat and/or vegetables with seasonings, while stock is made by simmering bones (with or without meat) along with vegetables and seasonings. Broth is often seasoned and ready to use as a base for soups, while stock is a more neutral base that can be used in various recipes.
- How can I store fresh herbs to make them last longer?
- Fresh herbs can be stored in the fridge in a few ways. One common method is to wrap them in a damp paper towel and place them in a resealable plastic bag. Alternatively, you can store them upright in a glass of water, like a bouquet.
- What is the best way to reheat leftovers to maintain their quality?
- For best results, reheat leftovers gently in an oven or on the stove over low to medium heat. This helps to maintain the texture and flavour. Microwaving is also an option for convenience, but it may affect the texture of certain dishes.
- How can I make a gluten-free flour blend for baking?
- A basic gluten-free flour blend can be made by combining equal parts of gluten-free flours like rice flour, potato flour, and tapioca flour. Xanthan gum or guar gum can also be added to improve the texture of baked goods.
- What is the best way to season a cast iron skillet?
- To season a cast iron skillet, coat it with a thin layer of vegetable oil or shortening and bake it upside down in a preheated oven at 180°C for about an hour. Allow it to cool in the oven before using.
- How can I rescue a dish that’s too salty?
- If a dish is too salty, you can try balancing it out by adding a neutral, unsalted ingredient like rice, potatoes, or pasta. You can also dilute the dish by adding more of the non-salty components.
