This homemade small-batch canned tomato sauce is proof that the best recipes often come from happy accidents. It’s simple enough for a beginner, forgiving enough for a distracted cook, and delicious enough to make you feel like a professional.

Ingredients

Scale
  • 5 pounds fresh Roma or San Marzano tomatoes
  • 6–8 cloves garlic, smashed
  • 1 large yellow onion, quartered
  • 1/4 cup extra-virgin olive oil
  • 2 teaspoons kosher salt (plus more to taste)
  • 1/2 cup fresh basil, loosely packed (optional)
  • 2 tablespoons bottled lemon juice
  • Canning salt (optional, for long-term storage)

Instructions

  1. Preheat your oven to 400°F. Wash your tomatoes thoroughly and remove the stems. Cut larger tomatoes in half, and leave cherry or grape tomatoes whole.
  2. Roast the Tomatoes (45-60 minutes): Arrange the tomatoes cut-side down on your baking sheet. Tuck the smashed garlic cloves and onion quarters in between the tomatoes. Drizzle everything with olive oil and sprinkle with salt. Roast for 45-60 minutes, until the tomatoes are soft and starting to caramelize. The skins should be wrinkled and slightly charred in spots. The garlic should be golden and tender.
  3. Cool Slightly (10 minutes): Let the baking sheet cool on a wire rack for about 10 minutes. This makes the tomatoes easier to handle and prevents steam burns when you blend them.
  4. Process the Tomatoes: If using a food mill, set it over a large bowl and work the tomatoes through in batches. If using an immersion blender, transfer the roasted tomatoes, garlic, and onions to a large pot. Blend until smooth. If using a regular blender, work in batches and leave the center cap off to let steam escape. Cover with a kitchen towel instead of the lid to prevent explosions.
  5. Simmer and Reduce (20-30 minutes): Pour the blended sauce into a large pot. Bring it to a gentle simmer over medium heat, then reduce the heat to low. Let it simmer uncovered for 20-30 minutes, stirring occasionally. The sauce should thicken slightly and reduce by about a quarter. Taste and adjust salt. If you’re adding fresh basil, stir it in during the last 10 minutes.
  6. Prepare Your Canning Equipment: While the sauce simmers, wash your jars, lids, and bands in hot soapy water. Rinse well. Place the jars in your water bath canner or stockpot and cover with water. Bring to a simmer (180°F) and keep the jars hot until you’re ready to fill them. Place the lids in a small bowl of hot water to soften the rubber seals.
  7. Add Lemon Juice to Jars: Add 1 tablespoon of bottled lemon juice to each pint jar (or 1/2 tablespoon for half-pints). This ensures the sauce is acidic enough for safe water bath canning.
  8. Fill the Jars: Using your canning funnel, ladle the hot sauce into the hot jars, leaving 1/2 inch of headspace. Run a clean chopstick or bubble remover around the inside of each jar to release any trapped air. Wipe the rims with a clean, damp paper towel. Center the lids on the jars and screw on the bands until fingertip-tight — don’t overtighten.
  9. Process in Water Bath: Place the filled jars in the canner rack and lower them into the boiling water. Make sure the water covers the jars by at least 1 inch. Bring to a full rolling boil, then start your timer. Process pint jars for 35 minutes, half-pints for 25 minutes. Adjust for altitude if you’re above 1,000 feet.
  10. Cool and Check Seals: After processing, turn off the heat and let the jars sit in the water for 5 minutes. Remove them with your jar lifter and place them on a kitchen towel on the counter. Leave them undisturbed for 12-24 hours. You’ll hear the satisfying ‘pop’ as each jar seals. After 24 hours, press the center of each lid — if it doesn’t flex, it’s sealed. Label and store in a cool, dark place.

Notes

Don’t skip the roasting — it concentrates the sugars and adds smoky depth. Watch your garlic to prevent burning. Use a thermometer for canning to ensure proper sealing. Don’t overfill jars; maintain 1/2-inch headspace. Let the sauce rest for a week or two for best flavor. For safe canning, always add bottled lemon juice.
