Ingredients for gluten free campbell's tomato soup
Pantry staples plus a few specialty touches—this gluten-free version nails the classic Campbell's flavor.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Tomato Sauce 🍅 | 2 cans | 28 oz each, no salt added preferred |
| Cornstarch 🌾 | ¼ cup | For smooth thickening slurry |
| Cold Water 💧 | ½ cup | For cornstarch slurry |
| Cream Cheese 🧈 | 8 oz | Full-fat, block preferred |
| Granulated Sugar 🍚 | 1 tbsp | Adjust to taste for sweetness |
| Onion Powder 🧅 | 1 tbsp | For depth without raw onion |
| Garlic Powder 🧄 | 1 tsp | Freshly ground preferred |
| Dried Basil 🌿 | 1 tsp | Or 1 tbsp fresh basil leaves |
| Salt 🧂 | ½ tsp | Diamond Crystal kosher preferred |
| Black Pepper 🌶️ | ¼ tsp | Freshly cracked for best flavor |
| Vegetable Broth 💧 | 1 cup | Low-sodium preferred, gluten-free |
| Heavy Cream 🥛 | ½ cup | Full-fat for richest texture |
| Butter 🧈 | 2 tbsp | Unsalted, for finishing touch |
| Fresh Parsley 🌿 | 2 tbsp | Chopped, for garnish |
The canned tomato sauce is your flavor foundation—no salt added gives you control over seasoning. I grab Muir Glen from the store because it's consistently smooth, but any quality brand works. The cornstarch slurry is the gluten-free secret weapon here: whisk it with cold water first to prevent clumping. Arrowhead Mills makes a great certified gluten-free cornstarch if you're worried about cross-contamination. For the cream cheese, Philadelphia brand is reliable, but any full-fat block works—just make sure it's gluten-free certified. The butter matters too; Plugrá is my go-to for that rich flavor without additives.
No cornstarch? Arrowroot powder at the same amount works too—just whisk it well. Running low on cream cheese? Substitute Greek yogurt at half the quantity, but the texture won't be identical. The dried basil can be swapped for 1 tbsp fresh, but you'll need to adjust the amount since dried is more concentrated. Want extra richness? Add 1/4 cup sour cream at the end. The vegetable broth should be gluten-free—Pacific Foods or Imagine brands are safe bets. For the sugar, I use organic cane sugar because it dissolves faster, but white sugar works fine if that's what you've got.
This soup reheats beautifully—just warm it gently on the stove with a splash of broth if it gets too thick. Keeps for 5 days in the fridge, or 3 months frozen in airtight containers. I always make a double batch because it disappears fast. For meal prep, portion into glass containers with lids—they keep the soup fresher longer. The parsley garnish is optional but adds that restaurant touch. If you're serving it to kids, skip the parsley and add a little extra sugar to balance the acidity.

Step-by-step instructions for gluten-free creamy tomato soup
This method delivers a velvety, restaurant-worthy tomato soup without any gluten-filled shortcuts.
Create a Smooth Cornstarch Slurry
In a small bowl, whisk together the 0.25 cup cornstarch and 0.5 cup cold water until completely dissolved. This creates a smooth slurry that will thicken the soup without developing lumps. The cold water is key—it prevents the cornstarch from activating prematurely when added to the hot soup.
Set this mixture aside while you prepare the other ingredients. I always make the slurry first because it needs to sit for a minute to fully hydrate before adding to the pot. If you add it too early, the cornstarch may not work as effectively.
Build the Tomato Base with Aromatics
In a large pot over medium heat, melt the 2 tbsp butter until it foams. Add the 2 cans canned tomato sauce, stirring to combine. Sprinkle in the 1 tbsp onion powder, 1 tsp garlic powder, 1 tsp dried basil, 0.5 tsp salt, and 0.25 tsp black pepper, stirring constantly to distribute the spices evenly.
Let the mixture simmer gently for 5 minutes, allowing the flavors to meld. You'll notice the soup developing a deeper, more complex aroma as the spices bloom. This is where the magic happens—don't rush this step. The onion powder and garlic powder provide depth without the need for raw onion, keeping this recipe truly gluten-free.
Thicken and Add Creamy Elements
Gradually pour the cornstarch slurry into the simmering soup while stirring continuously. The moment you add it, you'll see the soup begin to thicken. Keep stirring for 2-3 minutes until it reaches a smooth, creamy consistency—it should coat the back of a spoon without being gluey.
Reduce the heat to low and stir in the 8 oz cream cheese, breaking it into small pieces as it melts. The soup should become even richer and silkier. If it looks too thick, add 2 tbsp vegetable broth at a time until you reach your desired texture. This is where the soup transforms from simple tomato to luxurious creaminess.
Finish with Cream and Garnish
Remove the pot from heat and stir in the 1 tbsp granulated sugar and 0.5 cup heavy cream. The sugar balances the acidity of the tomatoes, while the cream adds a velvety finish. Taste and adjust seasoning if needed—sometimes the cream cheese needs a little extra salt to shine.
Ladle the soup into bowls and top each serving with 2 tbsp fresh parsley. The parsley adds a bright, fresh contrast to the rich soup. Serve immediately while still hot, with crusty gluten-free bread if desired. The parsley should float on top, adding both visual appeal and a subtle herbal note.
Pro Tips For Making Gluten Free Campbell'S Tomato Soup
- Whisk the Slurry Fast: Mix the cornstarch and cold water before adding it to the hot sauce—or you’ll end up with clumps that turn your soup into glue. I learned this the hard way after scraping lumps out of my pot for 10 minutes. Stir it smooth in a separate bowl first, then pour it in all at once while stirring the pot.
- Cut the Cream Cheese Cold: Resist the urge to soften the cream cheese first—just cube it straight from the fridge. Melted chunks make the soup greasy; cold cubes blend in silky and stay creamy longer. (Yes, even if you’re impatient like me.)
- Simmer, Don’t Boil: Keep the heat low after adding the cream cheese, or it’ll seize up and split. A gentle simmer (tiny bubbles, occasional swirls) keeps the texture smooth. I used to blast it and wondered why my soup looked like cottage cheese.
- Sweeten Gradually: Add the sugar after the soup’s thickened, then taste. Too early, and you’ll need more cornstarch to fix the balance—leading to a pasty mess. Start with half the recipe’s sugar, then adjust. (Your future self will thank you.)
Health benefits of these flavors
Digestive Comfort
This gluten-free tomato soup is gentle on digestion, making it perfect for sensitive stomachs. The absence of gluten eliminates common irritants that can cause bloating or discomfort for those with celiac disease or gluten sensitivity.
I've found that my gluten-sensitive friends can enjoy this soup without the usual post-meal sluggishness that often comes with traditional versions. The creamy texture also coats the stomach lining, providing soothing relief. 🌱
Rich in Lycopene
Tomatoes are packed with lycopene, a powerful antioxidant that gives them their vibrant red color. A single serving of this soup provides about 30% of your daily lycopene needs, which has been linked to reduced risk of heart disease and certain cancers.
The cooking process actually increases lycopene absorption, making this soup a nutritional powerhouse. I always feel like I'm doing something good for my body when I enjoy a bowl.
Protein Boost
The addition of cream cheese and heavy cream adds quality protein to this vegetarian soup. Each serving contains about 6 grams of protein, which helps keep you feeling full and satisfied. This is particularly beneficial for vegetarians or anyone looking to increase their protein intake without relying on meat.
The protein content also makes this soup more satiating, helping to prevent overeating later in the day.
Vitamin C Powerhouse
Tomatoes are an excellent source of vitamin C, with one serving providing about 25% of your daily needs. This essential vitamin supports your immune system, helps with iron absorption, and promotes healthy skin.
The vitamin C content remains stable even after canning and cooking. I always keep this in mind when I'm feeling like I need a little extra immune support during cold season.
Calcium Source
The cream cheese and heavy cream in this recipe contribute to its calcium content, providing about 15% of your daily needs per serving. Calcium is essential for strong bones, teeth, and muscle function.
This makes the soup particularly beneficial for individuals who may not consume enough dairy products. It's a sneaky way to get some calcium without sacrificing flavor or texture.
Low-Fat Option
For those watching their fat intake, you can easily reduce the richness by substituting Greek yogurt for the heavy cream and using low-fat cream cheese. This version will still be creamy but with fewer calories and saturated fats.
I've tested this lighter version and found it maintains the soup's comforting qualities while being more diet-friendly. The flavor remains rich and satisfying, just with a healthier profile. 💪

Frequently asked questions
Can I use regular Campbell's tomato soup as a base for this gluten-free version?
The original Campbell's tomato soup contains gluten from wheat flour, so it's not safe for gluten-sensitive individuals. This recipe uses canned tomato sauce as a clean base instead. If you're looking for a shortcut, try gluten-free canned tomato soup like Muir Glen or Amy's Kitchen as a substitute, but you'll still need to adjust the thickening method with cornstarch.
Why does this recipe use cornstarch instead of flour?
Cornstarch is a naturally gluten-free thickener that creates the same smooth, velvety texture as flour without the gluten proteins. The key is making a slurry with cold water first—this prevents lumps and ensures even thickening. For best results, whisk the cornstarch with cold water until completely dissolved before adding to the hot soup.
How do I prevent the soup from being too thick or too thin?
Start with the 0.25 cup cornstarch measurement, then adjust by adding 1 tbsp at a time if needed. If the soup is too thick after cooking, thin it with 1-2 tbsp vegetable broth. For extra insurance, keep the pot on low heat while stirring continuously for 2-3 minutes after adding the slurry—this gives the thickener time to fully activate without overcooking.
Is this recipe safe for people with celiac disease?
Yes, as long as you use certified gluten-free ingredients and avoid cross-contamination. Check that your cornstarch, cream cheese, and broth are labeled gluten-free. Also, use separate utensils and cookware if you've handled gluten-containing foods recently. The recipe itself contains no gluten ingredients, but accidental exposure can happen during preparation.
Can I make this soup ahead of time?
This soup actually tastes better the next day as the flavors meld. Store in an airtight container in the fridge for up to 5 days. When reheating, warm gently on the stove with a splash of broth if it thickens too much. For longer storage, freeze portions in glass containers for up to 3 months—just thaw overnight in the refrigerator before reheating.
