Here’s a detailed guide for making home-canned vegetable soup in Mason jars with proper steps for safety, flavor, and long-term storage:
Home-Canned Vegetable Soup in Mason Jars
Canning vegetable soup at home is a great way to have healthy, ready-to-eat meals. Using Mason jars ensures freshness and long-term storage.
Ingredients (Makes about 6–8 pint jars)
- 2 cups chopped onions
- 2 cups chopped carrots
- 2 cups chopped celery
- 3 cups chopped potatoes
- 2 cups green beans, chopped
- 2 cups corn kernels
- 2 cups diced tomatoes (fresh or canned)
- 6 cups vegetable or chicken broth
- 2–3 tablespoons olive oil or butter
- 2 teaspoons salt (adjust to taste)
- 1 teaspoon black pepper
- 1–2 teaspoons dried herbs (thyme, parsley, or basil)
- Optional: garlic, bay leaves, or other vegetables
Instructions
1. Prepare the Vegetables
- Wash, peel, and chop all vegetables into bite-sized pieces.
- Keep potatoes and onions in cold water until ready to use to prevent discoloration.
2. Sauté Aromatics
- In a large pot, heat olive oil or butter over medium heat.
- Sauté onions, celery, and garlic until fragrant (about 5 minutes).
3. Combine Soup Ingredients
- Add carrots, potatoes, green beans, corn, tomatoes, broth, salt, pepper, and herbs.
- Bring to a gentle boil and simmer for 10–15 minutes.
- Do not overcook; vegetables should be slightly firm.
4. Prepare Mason Jars
- Sterilize jars by boiling them in water for 10 minutes or running them through a hot dishwasher cycle.
- Keep jars warm to avoid cracking when adding hot soup.
5. Fill Jars
- Carefully ladle hot soup into sterilized jars, leaving 1–1.5 inches of headspace at the top.
- Remove air bubbles by gently tapping jars or using a non-metal utensil.
- Wipe rims clean and seal with sterilized lids.
6. Process Jars in a Pressure Canner
- Vegetable soup is low-acid, so a pressure canner is required to prevent bacterial growth:
- Place jars in a pressure canner with 2–3 inches of water.
- Process pint jars at 10–11 psi for 75 minutes (adjust for altitude).
- Carefully remove jars and let cool for 12–24 hours.
7. Check Seals and Store
- Lids should not flex up and down when pressed.
- Store in a cool, dark place for up to 12 months.
- Refrigerate after opening and consume within 3–4 days.
Tips for Best Results
- Avoid adding dairy, pasta, or rice before canning; add them fresh when reheating.
- Use fresh, firm vegetables for better texture.
- Label jars with date and contents for easy tracking.
This method gives you ready-to-eat, nutrient-rich vegetable soup straight from your pantry whenever you need it.
