Ingredients for copycat campbell's tomato soup recipe for canning
Twelve simple ingredients transform into nostalgic, restaurant-quality tomato soup perfect for canning and pantry storage.
| Ingredient | Amount | Notes |
|---|---|---|
| High-Quality Canned Tomatoes 🍅 | 6 cans | San Marzano preferred, 28 oz each |
| Yellow Onions 🧅 | 3 whole | Medium size, thinly sliced |
| Granulated Sugar 🍚 | ½ cup | White or brown preferred |
| Salt 🧂 | 1 ½ tbsp | Diamond Crystal kosher salt |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Garlic Cloves 🧄 | 6 cloves | Minced for depth of flavor |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | For sautéing onions |
| All-Purpose Flour 🌾 | ¼ cup | For thickening consistency |
| Dried Basil 🌿 | 1 tbsp | Or 0.25 cup fresh basil |
| Dried Oregano 🍃 | 1 tsp | Italian variety preferred |
| Dried Thyme 🌿 | ½ tsp | Or 1 tsp fresh thyme |
| Water 💧 | 8 cups | Filtered preferred |
| Pint Glass Jars 🍶 | 12 whole | Mason jars for canning |
| Lid Bands 🔗 | 12 whole | New for each jar |
The tomatoes are the heart of this recipe—San Marzano cans have that perfect balance of sweetness and acidity that Campbell's nailed. Ball or Kerr jars are your best bet for canning, but any clean, sterilized mason jar will work. For the onions, yellow onions caramelize beautifully, but red onions add a subtle sweetness if you prefer. The sugar isn't just for sweetness—it helps balance the acidity, which is critical for safe canning. I always grab Diamond Crystal kosher salt
No San Marzano tomatoes? Crushed tomatoes in 28 oz cans work in a pinch, but you might need an extra can or two for the same texture. Running short on fresh basil? Dried basil at one-third the amount works, but it lacks that bright freshness. The olive oil is non-negotiable for sautéing—extra-virgin adds a fruity depth that cheap oil misses. For the flour, all-purpose works fine, but if you've got bread flour on hand, its higher protein content gives a slightly thicker texture. The spices are where the magic happens—Italian oregano has a different profile than Mexican, so don't swap them unless you're experimenting. This soup tastes even better after canning—3-4 days in the fridge lets the flavors meld perfectly. For canning, sterilize jars in boiling water for 10 minutes, then fill with hot soup, leaving 1-inch headspace. Process pints in a pressure canner for 90 minutes at 10 pounds pressure. Store in a cool, dark place for up to 18 months. I always label mine with the date—Ball brand canning lids are my go-to for reliability. The first batch is always the best—you'll want to make a dozen jars!

Step-by-step instructions for pressure-canning tomato soup
Here's how to capture that iconic Campbell's flavor in your own pantry—step by step.
🍳 Step 1: Sauté Onions and Garlic for Depth of Flavor
Heat the 0.25 cup extra-virgin olive oil in a large stockpot over medium heat. Add the 3 whole yellow onions, sliced into ¼-inch strips, and cook for 8-10 minutes until they're soft and translucent with just a hint of golden color at the edges. This slow cook time ensures the onions melt into the soup rather than remaining distinct pieces.
Reduce heat to medium-low and add the 6 cloves minced garlic. Cook for another 1-2 minutes until fragrant—but don't let it brown. Garlic burns quickly, and that bitter taste will ruin your soup. Stir constantly during this final minute to prevent scorching. The aroma should fill your kitchen, signaling you're on the right track.
🥘 Step 2: Build the Soup Base with Tomatoes and Seasonings
Add the 6 cans high-quality canned tomatoes (with juices), 0.5 cup granulated sugar, 1.5 tbsp salt, 0.5 tsp ground black pepper, 1 tbsp dried basil, 1 tsp dried oregano, and 0.5 tsp dried thyme to the pot. Stir well to combine, then bring everything to a gentle boil over medium-high heat. Once boiling, reduce heat to medium-low and let it simmer uncovered for 20 minutes.
Here's where the magic happens: the spices meld with the tomatoes, and the sugar begins to caramelize slightly, deepening the flavor. Stir occasionally to prevent the bottom from sticking—this is especially important since we're not adding any thickeners yet. You'll notice the soup develops a rich, velvety texture as it simmers, and the aroma becomes irresistibly comforting.
🍳 Step 3: Thicken and Prepare for Canning
In a small bowl, whisk together the 0.25 cup all-purpose flour with 1 cup of the soup to create a smooth slurry. Slowly pour this mixture back into the pot while stirring constantly over medium heat. Bring to a gentle boil again, then reduce heat to medium-low and simmer for another 10 minutes, stirring frequently. This step ensures your soup has that perfect Campbell's-like thickness without being gluey.
After simmering, taste and adjust seasoning if needed—you might find the flavors need a touch more salt or sweetness. Add the remaining 7 cups water to reach your desired consistency. The soup should be smooth with no visible lumps, and the flavors should be fully developed. Let it cool to room temperature before canning—this is crucial for safe processing.
⏰ Step 4: Fill and Process Jars for Long-Term Storage
Ladle the cooled soup into the 12 whole pint glass jars, leaving ½-inch headspace at the top. Use a clean spoon or ladle to remove any foam or bubbles that rise to the surface. Wipe the jar rims with a damp cloth to ensure a perfect seal. Place the new lid bands on the jars, then screw on the lids fingertip-tight.
Process the jars in a pressure canner according to manufacturer instructions for pint-sized jars. For altitudes below 1,000 feet, process at 10 pounds pressure for 75 minutes. This high pressure ensures your soup remains safe to eat for up to 18 months. Once done, let the pressure naturally return to zero before opening the canner lid. Remove the jars and let them cool completely on a towel-lined surface—you'll hear the satisfying "ping" as the lids seal.
🔪 Step 5: Store and Enjoy Your Pantry Staple
Once completely cooled, check that all lids are sealed by pressing the center—it should not pop up. Store the jars in a cool, dark place. When ready to use, simply open a jar and heat the soup gently in a saucepan over medium-low heat, stirring occasionally. The texture should be creamy and the flavors rich—just like the classic you remember, but with the satisfaction of homemade quality.
This soup makes a perfect base for grilled cheese sandwiches, a comforting bowl on a cold day, or even a hearty pasta sauce. The beauty of canning is having your favorite flavors ready whenever you need them—no more worrying about store-bought versions that never quite measure up.
Pro Tips For Making Copycat Campbell'S Tomato Soup Recipe For Canning
- CRUSH THE ONIONS: I learned this the hard way—chopping onions into tiny, even pieces (about 1/4-inch dice) makes them dissolve smoothly into the soup instead of leaving stubborn chunks. No one wants to bite into onion surprises in canned tomato soup.
- SIMMER LOW AND SLOW: High heat turns this soup into glue. Once the tomatoes and onions are cooked down, drop the heat to a bare simmer (just tiny bubbles) and let it work for at least 20 minutes. Patience here keeps the texture velvety, not pasty.
- SALT IN STAGES: Don’t dump all the salt at once. Add half at the start, then taste again before canning—especially if using low-sodium tomatoes. Adjusting later is nearly impossible once sealed, and you’ll end up with a bland batch or a salty disaster.
- USE A SPLASH OF VINEGAR: Sounds weird, but it works: A tablespoon of apple cider vinegar brightens the flavor and cuts through the sweetness of the sugar. Skip it, and the soup can taste flat, even if the recipe looks perfect. (Yes, even if you’re impatient like me.)
Regional styles of this copycat campbell's tomato soup recipe for canning
Southern Comfort Style
In the South, we take tomato soup to another level by adding a touch of smoked paprika—just ½ teaspoon—and a splash of hot sauce (like Crystal or Tabasco) to the finished soup.
This gives it that familiar kick that reminds me of Nana Mae’s diner. I also like to serve it with buttery cornbread on the side, because nothing says Southern comfort like that combo. 💛
Italian Grandma’s Twist
For an Italian-inspired variation, swap the oregano for ½ teaspoon dried rosemary and add 1 teaspoon red pepper flakes for a subtle heat. Use San Marzano tomatoes (if you haven’t already) and finish with a drizzle of extra-virgin olive oil and a sprinkle of grated Parmesan before canning.
This version tastes like Nonna’s kitchen—rich, aromatic, and full of love. The rosemary adds a piney depth that pairs perfectly with the tomatoes.
Spicy Southwest Kick
If you love a little heat, this regional twist is for you. Stir in 1 teaspoon ground cumin and ½ teaspoon chili powder with the spices, and add 1 diced jalapeño (seeds removed) when sautéing the onions.
After canning, top each serving with crumbled cotija cheese and a dollop of sour cream. This version feels like a cross between tomato soup and chili—perfect for cooler Austin evenings when you crave something hearty but still creamy.
Creamy New England Version
For a velvety texture, blend ½ cup of the soup with ½ cup heavy cream after canning (just before serving). This Northern twist adds a luxurious mouthfeel that feels extra cozy.
Pair it with crusty sourdough bread and a sprinkle of black pepper—it’s the kind of soup that makes you want to curl up by a fire. I first tried this version at a bed-and-breakfast in Vermont, and it’s been a staple in my freezer ever since.
Herb-Infused French Style
For a more sophisticated take, infuse the soup with 1 sprig fresh thyme and 1 bay leaf while simmering. Remove them before canning, but the subtle herbal notes linger beautifully. Finish each serving with a swirl of crème fraîche and a sprinkle of fresh chives.
This version feels fancy enough for a dinner party but still simple enough for a weeknight. It’s inspired by my time working in Asheville’s farm-to-table scene, where French techniques met Southern flavors in the most delicious ways.
Kid-Friendly Mild Version
For little ones (or picky eaters), reduce the garlic to 3 cloves and skip the black pepper entirely. Add ½ teaspoon ground cinnamon and ¼ teaspoon nutmeg for a subtle sweetness that kids love. Serve with buttered noodles or toast cutouts for fun shapes.
This version is what I make for Emma and Jack—it’s still rich and comforting, but without the bold flavors that might overwhelm younger palates. 🌟

Frequently asked questions
Can I use fresh tomatoes instead of canned for this recipe?
Fresh tomatoes won't work for this canning recipe because they lack the acidity needed for safe preservation. The canned tomatoes provide consistent acidity levels that prevent bacterial growth during storage. For fresh tomato flavor, try adding a small amount of tomato paste (about 1 tablespoon) to enhance depth, but always rely on canned tomatoes as the base for canning safety.
How do I adjust this recipe for water bath canning instead of pressure canning?
This recipe requires pressure canning because tomato soup is a low-acid food that needs higher heat to kill bacteria. Water bath canning is only safe for high-acid foods like pickles or jams. For this soup, pressure canning at 10 pounds for 75 minutes is the only safe method that matches Campbell's shelf-stable quality.
Will this soup thicken more after canning?
Yes! The soup often thickens slightly after canning as the starches settle. If you prefer a thinner consistency, add ½ cup water per quart jar before processing. The flour slurry we use creates a stable texture that won't separate, but the natural reduction during canning may intensify the thickness slightly.
Can I add cream or milk to this canned soup?
No, you should never add dairy to canned tomato soup after processing. The heat of canning sterilizes the soup, but adding dairy afterward creates a perfect environment for bacterial growth. Instead, stir in cream or milk when reheating fresh portions from your jars—just heat it gently on the stove until steaming, then stir in the dairy.
What if my jars don't seal properly during canning?
Don't worry—unsealed jars are common with beginners! Check seals after 12-24 hours. If a jar didn't seal, refrigerate the soup and use it within 5-7 days. Common causes include insufficient headspace, dirty jar rims, or underprocessing. Always check your pressure canner gauge works properly and maintain 10 pounds pressure throughout the full 75-minute processing time.
