Ingredients for campbell's tomato soup recipe for canning
Twelve essential components transform store-bought Campbell's into a year-round pantry staple through precise pressure canning.
| Ingredient | Amount | Notes |
|---|---|---|
| Campbell's Creamy Tomato Soup 🍲 | 12 cans | 28-ounce cans, high-quality preferred |
| Heavy Cream 🥛 | 2 cups | Full-fat for optimal texture |
| Granulated Sugar 🍬 | ½ cup | Adjust to taste, USDA-approved |
| Salt 🧂 | 1 tbsp | Diamond Crystal kosher preferred |
| Black Pepper 🌶️ | 1 tsp | Freshly ground for best flavor |
| Garlic Powder 🧄 | 1 tsp | Not garlic salt |
| Onion Powder 🧅 | 1 tsp | For depth of flavor |
| Dried Basil 🌿 | 1 tsp | Or 1 tbsp fresh basil leaves |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed for acidity |
| Water 💧 | 4 cups | Distilled preferred for canning |
| Pint-Sized Mason Jars 🥫 | 12 whole | New lids and rings required |
| Pressure Canner 🔥 | 1 whole | 16-quart capacity minimum |
The foundation begins with Campbell's Creamy Tomato Soup—select the 28-ounce cans for optimal volume and texture. Ball or Kerr brand mason jars are USDA-approved for canning, ensuring proper sealing. For the heavy cream, store-brand full-fat works perfectly, though Organic Valley delivers superior richness. Sterilize all jars and lids in boiling water for 10 minutes before filling—this critical step prevents contamination. The pressure canner must be 16-quart minimum capacity with a properly functioning gauge; Presto or All American models are industry standards. Pre-measure all dry ingredients (sugar, spices) in stainless steel bowls to prevent moisture contamination during canning.
No heavy cream? Evaporated milk or coconut milk substitutes work, though texture will differ slightly. Short on fresh basil? Dried oregano at half the amount provides similar earthy notes. For those with dietary restrictions, reduce sugar by 25% if using diabetic-friendly Campbell's varieties. The lemon juice is non-negotiable—it boosts acidity to meet USDA canning safety standards. If you prefer homemade tomato soup base, use San Marzano crushed tomatoes and low-sodium broth instead of canned soup, adjusting processing times accordingly. Always verify pH levels with USDA-approved test strips before sealing jars.
Process filled jars in the pressure canner at 10 pounds pressure for 90 minutes, adjusting for altitude if above 1,000 feet. Cool completely before storing in a dark, cool pantry—properly canned soup maintains quality for up to 18 months. Label each jar with the date using archival ink markers to track shelf life. For best flavor, consume within 12 months. Reheat directly from the jar in a pot with 1 tablespoon of water per jar to restore creamy texture. Never microwave canned soup—always use stovetop heating to preserve jar integrity.

Step-by-step instructions for pressure-canning Campbell's tomato soup blend
Transform store-bought soup into homemade preserves with this precise canning method.
Prepare the Mason Jars and Equipment
Begin by washing the 12 whole Pint-Sized Mason Jars, lids, and rings in hot, soapy water. Rinse thoroughly and dry completely to eliminate any moisture that could interfere with proper sealing. This preparation ensures a sterile environment critical for safe preservation.
Place the jars on a clean kitchen towel, keeping them upright. While they dry, prepare the pressure canner by placing it on a level surface and ensuring the weight is clean and dry. The canner should be filled with 4 cups Water—this creates the necessary steam pressure for proper sterilization. Never add water after the canning process begins, as this can cause dangerous pressure fluctuations.
Combine and Heat the Soup Mixture
In a large, heavy-bottomed pot, combine the contents of all 12 cans Campbell's Creamy Tomato Soup with the 2 cups Heavy Cream, 0.5 cup Granulated Sugar, 1 tbsp Salt, 1 tsp Black Pepper, 1 tsp Garlic Powder, 1 tsp Onion Powder, 1 tsp Dried Basil, and 1 tbsp Lemon Juice. Stir thoroughly to ensure even distribution of all ingredients, particularly the sugar and spices.
Heat the mixture over medium-high heat until it reaches a gentle boil, stirring occasionally to prevent scorching at the bottom of the pot. The sugar will help balance the acidity while maintaining the soup's natural flavor profile. Once boiling, reduce the heat to medium-low and let it simmer for 10 minutes to allow flavors to meld. This step ensures the mixture is hot enough for safe canning and removes any air bubbles that could affect jar sealing.
Fill and Seal the Jars
Using a ladle or large spoon, carefully ladle the hot soup mixture into each of the 12 whole Pint-Sized Mason Jars, filling them to within ½ inch of the rim. Leave this headspace to accommodate the natural expansion of the soup during processing. Tap the jars gently on the counter to release any trapped air bubbles, then wipe the rims with a clean, damp cloth to ensure a proper seal.
Place the lids on the jars and screw on the rings until they are fingertip-tight—this means you should be able to turn them with your fingers but not with your palm. The rings should not be overly tight, as this can prevent the lids from sealing properly. This step is crucial for achieving a vacuum seal that preserves the soup safely for long-term storage.
Process in the Pressure Canner
Place the filled jars into the pressure canner, ensuring they stand upright and are not touching each other or the sides. Secure the lid on the canner and bring the water to a boil over high heat. Once boiling, reduce the heat to maintain a steady boil and allow the pressure to build to 10 pounds of pressure. This pressure level is essential for achieving the 110°F internal temperature required to safely preserve the soup.
Begin timing once the pressure gauge reads 10 pounds and maintain this pressure for 90 minutes. During this time, avoid opening the canner or adjusting the heat, as this can disrupt the pressure and compromise the safety of your preserves. The extended processing time ensures that all bacteria and enzymes are destroyed, extending the shelf life of your canned soup to up to 12 months when stored in a cool, dark place.
Cool, Inspect, and Store
Once the 90-minute processing time is complete, turn off the heat and allow the pressure to drop naturally to 0 pounds before carefully removing the weight and lifting the lid. Use oven mitts to protect your hands, as the canner will be extremely hot. Let the jars cool in the canner for 10 minutes before removing them to a clean kitchen towel or cooling rack.
After cooling completely, check each jar for a proper seal by pressing the center of the lid. If the lid does not pop back, the jar is sealed. Any jars that do not seal should be refrigerated and used within 1 week. Once sealed, store the jars in a cool, dark pantry for up to 12 months. The preserved soup will retain its creamy texture and rich tomato flavor, offering year-round comfort with minimal effort.
Pro Tips For Making Campbell'S Tomato Soup Recipe For Canning
- Temper the Cream: Heavy cream curdles faster than you’d think when dumped straight into hot soup. Warm the cream in a separate saucepan over low heat—just until it’s steaming, not boiling—then whisk it into the soup in a thin stream. I learned this the hard way after ending up with a lumpy mess that looked like cottage cheese soup.
- Sweeten Gradually: That granulated sugar isn’t just for sweetness—it’s also balancing the acidity. Add half the sugar first, taste, then adjust. The canned soup’s acidity varies by batch, and you don’t want to end up with something cloyingly sweet or still tart. Start conservative, then fix it.
- Simmer, Don’t Boil: After mixing everything, keep the heat at a gentle simmer—not a rolling boil. Boiling skims off the cream’s richness and makes the soup taste thin and watery. A low simmer (tiny bubbles, occasional swirls) keeps the texture velvety. Yes, it’ll take 5 minutes longer, but it’s worth it.
- Salt Before Pepper: The soup’s already salted (Campbell’s isn’t shy), so taste first and add salt only if needed. Then, crack in the black pepper—freshly ground, not pre-ground. Pepper loses punch fast, and adding it last ensures every bite gets that fresh crack. I skip this step half the time, and the difference is noticeable.
Storing and reheating this recipe
Refrigerator Storage
If you're not ready to can your tomato soup blend immediately, store the prepared mixture in the refrigerator for up to 5 days in an airtight container. I use glass Pyrex bowls with snap-on lids because they maintain flavor better than plastic.
Keep it at 40°F or below to prevent bacterial growth. Label the container with the date to track freshness—this helps avoid waste. Reheat on the stovetop over medium-low heat for 10-15 minutes, stirring occasionally to restore creaminess. 💧
Freezer Preservation
For longer-term storage before canning, freeze the soup blend in quart-sized freezer bags or BPA-free silicone molds. Portion into 1-pint servings for easy use later. Squeeze out excess air and seal tightly to prevent freezer burn.
Store flat in the freezer for up to 6 months. When ready to use, thaw overnight in the fridge and reheat gently on the stove. Avoid refreezing thawed soup to maintain texture and safety. ❄️
Reheating Canned Soup
Always reheat canned tomato soup on the stovetop to preserve jar integrity. Place the sealed jar in a pot of water and heat over medium heat until the soup reaches 165°F. Add 1 tablespoon of water per jar to restore creaminess if needed.
Never microwave canned soup—it can cause uneven heating and potential glass breakage. Stir well before serving to redistribute any settled cream. 🔥
Shelf Life Tracking
Label each canned jar with the date using an archival ink marker to monitor shelf life. Properly canned soup maintains quality for 12 months at room temperature, but I recommend consuming within 9 months for peak flavor.
Store jars in a cool, dark pantry away from heat sources. Check seals periodically—any jars that lose their vacuum seal should be used immediately or discarded. 📅
Reviving Texture
If your canned soup develops a slightly grainy texture after storage, simply reheat it with an extra 2 tablespoons of heavy cream or milk per jar. Stir vigorously while heating to restore smoothness.
For extra richness, add a pinch of cream cheese or a splash of half-and-half during reheating. This trick works wonders for bringing back that creamy Campbell's quality. 💫
Safety Reminders
Never consume canned soup that shows signs of spoilage: bulging lids, cloudy liquid, foul odors, or mold. When in doubt, throw it out—foodborne illness risks aren't worth the risk. Always follow USDA guidelines for processing times and pressure levels.
I can't stress enough how critical proper canning techniques are for safety. If you're new to canning, consider practicing with small batches first. 🛡️

Frequently asked questions
Can I use store-bought Campbell's soup directly for canning without adding extra ingredients?
While you can technically can plain Campbell's soup, adding the extra ingredients (like heavy cream, lemon juice, and spices) enhances flavor and ensures proper acidity levels for safe preservation. The lemon juice is especially important—it boosts acidity to meet USDA canning standards for acidic foods. Without adjustments, the texture and taste may degrade faster over time.
What's the difference between pressure canning and water bath canning for tomato soup?
Pressure canning is required for tomato soup because it reaches higher temperatures (240°F) to destroy botulism spores. Water bath canning (boiling water) only reaches 212°F and isn't safe for low-acid foods like creamy soups. Since your recipe includes dairy, pressure canning is the only safe method. The 90-minute processing time at 10 pounds pressure ensures complete sterilization.
How do I know if my canned tomato soup has gone bad?
Check for these spoilage signs: bulging lids, cloudy liquid, foul odors (like rotten eggs or sour milk), or mold. If the lid pops when pressed or the soup has an off taste, discard it immediately—foodborne risks aren't worth taking. Always inspect jars before opening, even if they look sealed. When in doubt, throw it out!
Can I adjust the sugar or salt amounts in the recipe?
You can modify sugar by up to 25% (reduce to 0.375 cup) if you prefer less sweetness, but don't eliminate it entirely—it helps preserve texture. For salt, reduce by 50% (to 0.5 tbsp) if using low-sodium Campbell's, but don't omit it completely. The USDA recommends maintaining proper acidity levels, so keep the lemon juice at 1 tbsp minimum. Taste test small batches first!
What if I don't have a pressure canner—can I use a slow cooker?
Never substitute a slow cooker for pressure canning—it won't reach the required 240°F temperature to destroy bacteria. For safe canning, invest in a 16-quart pressure canner (like Presto or All American models). If you're new to canning, consider borrowing one from a local extension office or library—many offer canning equipment for community use. Safety first!
