Equipment You’ll Need

- Jar lifter
- Funnel
- Ladle
- Clean cloths or paper towels
Step-by-Step Instructions
1. Prepare the Tomatoes
- Wash tomatoes thoroughly.
- To peel: Bring a large pot of water to a boil. Score the bottom of each tomato with an “X” and blanch in boiling water for 30–60 seconds until skins loosen.
- Transfer to an ice bath, then peel and core the tomatoes.
2. Cook the Sauce
- In a large stockpot, heat olive oil over medium heat.
- Sauté chopped onion until soft (about 5 minutes), then add garlic and cook for another minute.
- Add peeled and chopped tomatoes.
- Simmer uncovered for 45–60 minutes, stirring occasionally, until tomatoes break down and mixture thickens.
3. Puree the Sauce
- Use an immersion blender for a smooth texture or pass the mixture through a food mill to remove seeds and skins.
4. Add Seasonings
- Stir in salt, sugar, and any desired herbs. Simmer for another 20 minutes to let flavors meld.
- Taste and adjust seasonings as needed.
5. Prepare the Jars
- While the sauce simmers, sterilize jars by washing them in hot, soapy water and placing them in boiling water for 10 minutes.
- Keep jars hot until ready to use.
- Heat lids in a small pot of simmering water (do not boil).
6. Add Lemon Juice
- To ensure safe acidity levels, add 2 tablespoons of bottled lemon juice to each pint jar (4 tablespoons for quarts).
7. Fill the Jars
- Using a funnel, ladle hot tomato sauce into jars, leaving 1/2 inch headspace.
- Wipe rims with a clean damp cloth to remove residue.
- Place lids on jars and screw on bands until fingertip-tight.
8. Process the Jars
- Place jars in a boiling water bath canner. Ensure jars are covered by at least 1 inch of water.
- Process pint jars for 35 minutes and quart jars for 40 minutes.
- Start timing when the water returns to a full boil.
9. Cool and Store
- Carefully remove jars using a jar lifter. Place on a towel and let cool undisturbed for 12-24 hours.
- Check seals: lids should not flex up and down when pressed.
- Label and store in a cool, dark place for up to 18 months.

Pro Tips for Perfect Tomato Sauce Canning
- Use bottled lemon juice, not fresh, to ensure consistent acidity for safe canning.
- Thicker sauce? Simmer longer to reduce water content.
- No food mill? Use a blender, but you may need to strain out seeds.
- Label everything! Include the date so you use the oldest jars first.
- Don’t skip headspace. It’s crucial for a proper seal and safe preservation.
Variations to Try
Herbed Tomato Sauce
Add a handful of fresh basil or thyme during the last 10 minutes of simmering. Use fresh herbs if you plan to refrigerate or freeze instead of canning.
Spicy Tomato Sauce
Add 1–2 teaspoons of red pepper flakes or minced jalapeño during the cooking stage.
Roasted Garlic Tomato Sauce
Roast garlic cloves in the oven and stir them in before pureeing for a deeper flavor.
Tomato Cream Sauce (Not for Canning)
After opening a jar, stir in a splash of cream and grated Parmesan for a quick weeknight pasta dinner.
Frequently Asked Questions (FAQs)
Q: Can I use cherry or slicing tomatoes instead of Roma?
A: Yes, but they have more water content. Expect a longer simmering time to reduce excess liquid.
Q: Do I need to add lemon juice?
A: Absolutely. It ensures the pH is low enough for safe water bath canning.
Q: Can I pressure can this sauce instead?
A: Yes, pressure canning is also safe and may preserve nutrients better. Follow a tested pressure canning guide for timing.
Q: How long will the sauce last?
A: Properly sealed jars can last 12–18 months in a cool, dark pantry.
Q: Can I freeze this sauce instead of canning?
A: Yes! Let the sauce cool, pour into freezer-safe containers, leaving room for expansion, and freeze for up to 6 months.
