Prep and Cook Time

• Preparation: 30 minutes
• Cooking: 1 hour
• Canning and Processing: 45 minutes
• Total Time: Approximately 2 hours 15 minutes

Yield

Yields approximately 6 pint jars (16 oz each) of rich, tangy tomato sauce.

Difficulty Level

Medium – ideal for home cooks with basic kitchen skills and a touch of patience.

Ingredients

• 10 lbs ripe plum tomatoes (preferably Roma or San Marzano for their meaty flesh)
• 2 cups finely chopped onions
• 6 cloves garlic, minced
• ½ cup extra virgin olive oil
• 1 tbsp sea salt
• 1 tbsp sugar (optional, balances acidity)
• 1 tsp freshly ground black pepper
• ½ cup fresh basil leaves, chopped
• 2 tbsp lemon juice (per pint jar, ensures safe acidity for canning)

Instructions

1. Select and Prepare the Tomatoes: Wash tomatoes thoroughly. Score a shallow “X” on the bottom of each tomato. Boil a large pot of water and blanch tomatoes for 45-60 seconds, then immediately plunge into ice water. Peel off skins easily starting at the scored “X.”
2. Core and Chop: Remove cores and roughly chop peeled tomatoes. Set aside.
3. Sauté Aromatics: In a large heavy-bottomed pot, heat olive oil over medium heat. Add onions and garlic, sauté until translucent and fragrant-about 5 minutes-stirring regularly to prevent burning.
4. Add Tomatoes: Stir in chopped tomatoes, sea salt, sugar, and black pepper. Bring to a gentle simmer.
5. Simmer the Sauce: Reduce heat and let the mixture simmer uncovered for 45-60 minutes, stirring occasionally to prevent sticking. The sauce should thicken and intensify in color and aroma.
6. Blend (Optional): For a smoother texture, use an immersion blender directly in the pot or carefully transfer batches to a blender. Blend to your desired consistency.
7. Add Fresh Basil: Stir in chopped basil during the last 5 minutes of cooking to preserve its bright flavor.
8. Prepare Jars and Lids: Sterilize pint jars and lids by boiling them for 10 minutes. Keep warm until ready to fill.
9. Fill Jars: Ladle hot sauce into each pint jar, leaving ½ inch headspace. Add 2 tablespoons lemon juice per jar to ensure proper acidity for safe canning.
10. Wipe Rims and Seal: Wipe the rims with a clean damp cloth to remove any residue. Place lids on and screw on bands until fingertip tight.
11. Process Jars: Place jars in a boiling water canner ensuring they’re covered by at least 1 inch of water. Process pint jars for 35 minutes. Adjust time for altitude if necessary.
12. Cool and Store: Carefully remove jars and place on a clean towel, allowing them to cool undisturbed for 12-24 hours. Check seals before storage-lids should not flex when pressed.

Tips for Success

• Tomato Selection: Choose tomatoes that are firm yet fully ripe for optimal flavor and fleshiness.
• Maintaining Acidity: Never skip adding lemon juice or citric acid to each jar-this is crucial for long-term, safe storage.
• Adjust to Taste: If you like a spicier sauce, add a pinch of red pepper flakes during simmering.
• Make Ahead: Reduce prep time by peeling and chopping tomatoes the day before and refrigerating overnight.
• Storage: Store sealed jars in a cool, dark place for up to one year. Refrigerate after opening and consume within one week.

Q&A

Q&A: Preserve the Flavor – Canning Tomato Sauce in Pint Jars Guide

Q1: Why should I can tomato sauce in pint jars instead of larger jars?
A1: Pint jars are the Goldilocks option-not too big, not too small. They ensure you use just the right amount of sauce in one go, reducing waste and preserving that fresh, sun-ripened flavor every time. Plus, smaller jars heat evenly and safely during processing, making your canning more foolproof.

Q2: What’s the secret to keeping homemade tomato sauce bursting with flavor after canning?
A2: The magic lies in freshness and acidity. Use ripe, vine-ripened tomatoes for natural sweetness, and add a splash of lemon juice or bottled citric acid to keep that vibrant taste and safe pH level. Also, simmer your sauce just right-long enough to meld flavors but not so long it loses that bright tomato zing.

Q3: How do I prepare my pint jars for canning tomato sauce?
A3: Start with squeaky-clean jars-wash them in hot, soapy water and rinse well. Then, sterilize by boiling or running through a hot dishwasher cycle. Keep the jars warm until you’re ready to fill; sudden temperature changes risk cracking your glass beauty!

Q4: Is a water bath canner sufficient for tomato sauce, or do I need a pressure canner?
A4: Good news-tomato sauce can be safely processed in a boiling water bath canner, thanks to the acid you add (like lemon juice). Just be sure to follow processing times carefully to zap those pesky bacteria and seal in flavor. Pressure canners? More for low-acid foods like meats and veggies-not necessary here.

Q5: What common mistakes should I avoid when canning tomato sauce in pint jars?
A5: Avoid these flavor-sappers and safety hazards: don’t skip acidifying your sauce, don’t fill jars to the brim (leave a half-inch headspace), and don’t rush the sealing process-let lids cool naturally for a tight, vacuum seal. Also, steer clear of overfilling your canner to ensure proper heat circulation.

Q6: How long can I store my canned tomato sauce in pint jars, and how do I know if it’s still good?
A6: Stored in a cool, dark place, your canned tomato sauce can be enjoyed for up to 12-18 months. Check for signs of spoilage-off odors, bulging lids, or funky colors-and when in doubt, toss it out. But most times, you’ll be rewarded with sauce that tastes garden-fresh all year round!

Q7: Can I customize my tomato sauce flavors before canning it in pint jars?
A7: Absolutely! Feel free to infuse your sauce with garlic, fresh basil, oregano, or a pinch of red pepper flakes. Just remember to add herbs and spices during the simmering phase for best flavor infusion. Avoid thickening agents like flour or cornstarch before canning-they don’t hold up well under heat and storage.

Preserving your homemade tomato sauce in pint jars is an art and a joy-capturing summer’s essence jar by jar for your kitchen’s future feasts. Happy canning!
