Why Can Fresh Tomatoes From the Garden?
Canning tomatoes preserves their natural taste and nutrients while preventing spoilage. Fresh tomatoes are highly perishable, and canning extends their shelf life up to 12-18 months. Home-canned tomatoes are free from preservatives and additives often found in store-bought products, giving you pure, garden-fresh flavor.
Key benefits include:
- Preserving peak-season freshness
- Reducing food waste
- Saving money on store-bought canned tomatoes
- Controlling ingredients for healthier meals
What You’ll Need: Essential Equipment for Canning Tomatoes
Before starting, gather your supplies to ensure a smooth canning process:
- Fresh, ripe tomatoes (preferably firm and blemish-free)
- Canning jars with two-piece lids (rings and flat lids)
- Large pot or water bath canner
- Jar lifter and funnel
- Ladle and bubble remover tool or a non-metallic spatula
- Clean towels
- Lemon juice or citric acid (to ensure acidity for safe canning)
Step-by-Step Process: How to Can Fresh Tomatoes From the Garden
Follow these clear, easy-to-follow steps to can your fresh tomatoes safely and effectively.
1. Prepare Your Tomatoes
- Wash tomatoes thoroughly under running water to remove dirt and debris.
- Remove stems and any bruised spots.
- Optional: Peel tomatoes by blanching them in boiling water for 30-60 seconds, then plunging them into ice water. The skins will slip off easily.
2. Sterilize Your Jars and Lids
- Wash jars, lids, and rings with hot, soapy water, rinse well.
- Place jars in a boiling water bath for 10 minutes to sterilize. Keep warm until ready to fill.
- Simmer lids in hot (not boiling) water to soften the sealing compound.
3. Add Acid for Safety
- Tomatoes have borderline acidity, so add 2 tablespoons of bottled lemon juice or ½ teaspoon of citric acid per quart jar (half the amount for pint jars).
- This step prevents bacterial growth and ensures safe preservation.
4. Pack the Tomatoes into Jars
- Cut tomatoes into halves or quarters, or crush them lightly.
- Pack tomatoes tightly into jars, leaving about ½ inch of headspace at the top.
- Pour hot tomato juice or boiling water over the tomatoes to cover, maintaining the headspace.
5. Remove Air Bubbles and Seal Jars
- Use a bubble remover tool or a non-metallic spatula to remove trapped air bubbles by gently sliding it around the jar’s inside.
- Wipe the jar rims clean with a damp cloth to ensure a good seal.
- Place lids on jars and screw on rings until fingertip tight.
6. Process Jars in a Boiling Water Bath
- Place jars in a water bath canner with at least 1-2 inches of water covering the jars.
- Bring water to a rolling boil and process pint jars for 40 minutes, quart jars for 45 minutes (adjust timing for altitude if necessary).
- Remove jars carefully using a jar lifter and place on a towel to cool undisturbed for 12-24 hours.
7. Check Seals and Store
- After cooling, check seals by pressing the center of each lid — it should not flex up or down.
- Remove screw bands and wipe jars clean.
- Label jars with date and contents, store in a cool, dark place.
Tips & Tricks for Perfect Canned Tomatoes Every Time
- Use firm, ripe tomatoes for the best texture and flavor preservation.
- Avoid overfilling jars; proper headspace is critical to prevent spoilage.
- Always use bottled lemon juice or citric acid rather than fresh lemon juice for consistent acidity.
- Follow processing times accurately based on your altitude to avoid under-processing.
- Never reuse flat lids from previous canning batches.
