What Ingredients You Will Need

This homemade tomato sauce from fresh tomatoes for canning uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without fuss. Most of these are pantry staples or garden-fresh, making the recipe accessible and adaptable.

• Fresh Tomatoes (about 10 pounds / 4.5 kg): Choose ripe, firm tomatoes like Roma or plum for the best sauce texture.
• Olive Oil (¼ cup / 60 ml): Adds richness and helps meld flavors.
• Onion (1 medium, finely chopped): Provides a subtle sweetness and depth.
• Garlic Cloves (3-4, minced): For that classic savory punch.
• Fresh Basil Leaves (about ½ cup, chopped): Adds bright herbal notes.
• Salt (2 teaspoons): Enhances natural tomato sweetness.
• Granulated Sugar (1 tablespoon, optional): Balances acidity if needed.
• Black Pepper (½ teaspoon freshly ground): For mild heat and flavor depth.
• Lemon Juice (2 tablespoons): Necessary for canning safety to maintain acidity.

I like to use California-grown Roma tomatoes when possible—they’re meaty and low in water, so the sauce thickens beautifully. If you’re lucky enough to have heirloom tomatoes, they work well too but may result in a slightly thinner sauce. For olive oil, a good-quality extra virgin like Colavita really brings out the flavor.

If you’re missing fresh basil, dried works in a pinch—just reduce quantity by half. For a dairy-free or vegan option, this sauce is naturally compliant. And if you want a low-sodium version, start with less salt and adjust after cooking.

Equipment Needed

Making homemade tomato sauce from fresh tomatoes for canning requires some basic kitchen tools and a few specialized items to get that perfect jar of goodness.

• Large Stockpot (at least 8 quarts / 7.5 liters): For simmering the sauce without crowding.
• Potato Masher or Immersion Blender: To break down tomatoes if you prefer a smoother sauce.
• Large Canning Jars (Mason jars, pint or quart size): Essential for preserving your sauce.
• Water Bath Canner or Large Pot with Rack: For safely processing jars.
• Jar Funnel and Ladle: Makes filling jars easier and less messy.
• Jar Lifter and Magnetic Lid Lifter: For safe handling of hot jars and lids.

If you don’t have a water bath canner, a large stockpot with a rack works just fine. I’ve used both, and while the canner speeds up the process, the pot method is budget-friendly and effective. Just be sure to keep an eye on water levels during processing to avoid any mishaps.

Keeping your jars and lids in hot water before use helps avoid breakage and ensures a better seal. Trust me, I’ve learned that the hard way!

Preparation Method

1. Prepare the Tomatoes (20-30 minutes): Start by washing your fresh tomatoes thoroughly. Then, score a small “X” on the bottom of each tomato with a sharp knife. Drop them into boiling water for 30-60 seconds until the skins loosen, then transfer immediately to an ice bath. This makes peeling a breeze—just slip the skins right off!
2. Chop and Cook (15 minutes): Core and roughly chop peeled tomatoes. In your large stockpot, heat olive oil over medium heat, then add chopped onions and garlic. Sauté until fragrant and translucent, about 5 minutes. Toss in tomatoes and bring to a gentle simmer.
3. Simmer and Mash (45-60 minutes): Let the mixture simmer uncovered, stirring occasionally to prevent sticking. Use a potato masher or immersion blender to break down tomatoes to your preferred consistency. This step thickens the sauce and melds flavors beautifully. Watch for the sauce to reduce by about one-third—this usually takes close to an hour.
4. Season and Add Basil (5 minutes): Stir in salt, pepper, sugar (if using), and fresh chopped basil. Let the sauce simmer for an additional 5 minutes to marry the flavors. Taste and adjust seasoning as needed.
5. Add Lemon Juice for Canning (2 minutes): Right before filling jars, stir in lemon juice to ensure safe acidity levels for canning.
6. Prepare Jars and Lids: While the sauce simmers, sterilize your canning jars and lids by boiling them in water or running through a hot dishwasher cycle. Keep jars warm until ready to fill.
7. Fill and Seal Jars (15 minutes): Using a jar funnel and ladle, fill hot jars with hot sauce, leaving about ½ inch (1.3 cm) of headspace. Wipe rims clean, place lids on top, and screw on bands fingertip tight.
8. Process in Water Bath (35 minutes): Submerge filled jars in boiling water, ensuring they’re covered by at least 1 inch (2.5 cm) of water. Process pint jars for 35 minutes, adjusting time if you’re at higher altitudes. Remove jars carefully and let cool on a towel or rack, undisturbed for 12-24 hours.
9. Check Seals and Store: Once cooled, press the center of each lid—if it doesn’t pop back, the jar is sealed. Label and store in a cool, dark place.

Pro tip: If your sauce is a bit too thin after simmering, simply cook it a little longer to reduce further. And don’t rush the cooling process; a proper seal is key to safe, long-lasting canned sauce.

Cooking Tips & Techniques

After making this homemade tomato sauce from fresh tomatoes for canning more times than I can count, I have a few tips that make all the difference.

• Choose the Right Tomatoes: Roma or plum tomatoes are your best bet—they have fewer seeds and less watery pulp, which means a thicker, richer sauce.
• Peeling is a Must: Don’t skip the blanch-and-peel step; tomato skins can add unwanted texture and bitterness.
• Low and Slow: Simmer the sauce gently to develop rich flavors without burning or sticking. Stir often near the end to prevent scorching.
• Adjust Acidity for Safety: Lemon juice isn’t just for flavor—it’s essential for preserving the sauce safely during canning. Don’t skip it!
• Watch Your Water Level: When processing jars, keep an eye on water levels to avoid exposing jars to air, which can break seals.
• Don’t Overfill Jars: Leave proper headspace to allow for sauce expansion during processing.

One time, I overfilled a jar and ended up with sauce bubbling out during canning—lesson learned! Also, blending some of the sauce before canning helps achieve a smooth texture, but I recommend leaving a little chunkiness for that homemade feel.

Variations & Adaptations

This homemade tomato sauce from fresh tomatoes for canning is wonderfully versatile, so feel free to make it your own with these ideas:

• Spicy Kick: Add red pepper flakes or chopped fresh chili peppers during the onion sauté step for a touch of heat.
• Herb Swap: Use oregano, thyme, or rosemary instead of basil for a different flavor profile. Dried herbs work well too—just reduce quantities.
• Chunky Style: Skip blending and leave the tomatoes chunky for a rustic sauce perfect on crusty bread or as a base for shakshuka.
• Low Sodium: Omit added salt and use fresh or dried herbs for flavor. Great for those watching sodium intake.
• Vegan-Friendly: This sauce is naturally vegan and dairy-free—just ensure your canning lids are free from animal products if needed.

I once tried roasting the tomatoes beforehand for a smoky flavor—it was a hit at a family barbecue, though it requires a bit more hands-on time. For a winter twist, add a splash of red wine during simmering to deepen the flavor.

Serving & Storage Suggestions

This homemade tomato sauce from fresh tomatoes for canning is best served warm, spooned over pasta, used as a pizza base, or stirred into soups and stews. A sprinkle of fresh parmesan or a drizzle of olive oil on top really brings out the flavors.

When reheating, warm gently on the stove or microwave, stirring occasionally. You’ll notice the flavors deepen and meld over time, so homemade tomato sauce from fresh tomatoes for canning only gets better as it sits.

Leftover sauce also freezes beautifully in ice cube trays—perfect for adding small amounts to recipes later.
