The Ultimate Guide to Preserving Tomatoes for Fall & Winter Dishes

When the garden (or farmers’ market) is overflowing with ripe, juicy tomatoes, it’s time to think ahead to cozy fall suppers—lasagna bubbling in the oven, slow-simmered spaghetti sauce, and rustic tomato soups. The best way to keep that peak-summer flavor alive? Preserve your tomatoes now so they’re ready when you need them later.

Method 1: Freezing Tomatoes

Freezing is quick, beginner-friendly, and keeps that fresh-from-the-vine flavor.
You can freeze them whole, chopped, or as a cooked sauce.

Option A – Freezing Whole or Chopped (Raw)

What You’ll Need:

• 4–5 lbs ripe tomatoes (about 10–12 medium)
• Sharp paring knife
• Large pot
• Slotted spoon
• Freezer-safe bags or containers
• Permanent marker

Steps:

1. Wash & Score: Rinse tomatoes and cut a small “X” on the bottom of each.
2. Blanch & Peel: Drop tomatoes into boiling water for 30–60 seconds until skins loosen. Transfer to ice water. Peel off skins.
3. Core & Chop (optional): Remove cores. Leave whole for sauces or chop for soups/stews.
4. Pack & Freeze: Place tomatoes in freezer bags, removing as much air as possible. Label with date. Lay flat to freeze for easy storage.

Freezer Life: 8–10 months
Yields: About 1 quart bag per 2 lbs of tomatoes.

Option B – Freezing as Sauce

What You’ll Need:

• 8 lbs ripe tomatoes (about 20 medium)
• 2 tsp salt (optional)
• Large pot, immersion blender
• Freezer containers or jars

Steps:

1. Prep Tomatoes: Wash, core, and roughly chop.
2. Cook Down: Place in a large pot, bring to a simmer over medium heat. Cook 45–60 minutes, stirring occasionally.
3. Blend (optional): Use an immersion blender for a smooth sauce or leave chunky.
4. Cool & Pack: Cool sauce completely before ladling into freezer-safe containers, leaving 1 inch headspace.
5. Label & Freeze.

Freezer Life: 8–12 months
Yields: About 4 quarts sauce.

Method 2: Canning/Jarring Tomatoes (Water Bath)

Perfect for shelf-stable storage—no freezer space required.
We’ll use the USDA-approved acidification method to ensure safety.

What You’ll Need:

21 lbs ripe tomatoes (about 55–60 medium) for 7 quarts
OR 13 lbs (about 35 medium) for 9 pints

½ tsp citric acid or 2 Tbsp bottled lemon juice per quart (half for pints)

1 tsp salt per quart (optional)

Canning jars with new lids & bands

Large pot or water bath canner

Jar lifter, funnel, ladle

Steps:

1. Prep Tomatoes: Wash and blanch as in freezing method. Peel skins and core.
2. Hot Pack Method (recommended): Cut into halves or quarters, add to a large pot, and boil gently for 5 minutes.
3. Acidify Jars: Add citric acid or lemon juice to each sterilized jar before filling.
4. Fill Jars: Pack hot tomatoes into jars, pressing to release juice, leaving ½ inch headspace. Add salt if desired.
5. Seal & Process: Wipe jar rims, apply lids, and process in boiling water—
   • Pints: 40 minutes
   • Quarts: 45 minutes
     (Adjust for altitude per USDA guidelines)
6. Cool & Store: Remove jars, let cool 12–24 hours. Check seals. Store in a cool, dark place.

Shelf Life: Up to 18 months.

Tips for Success

• Choose the Right Tomatoes: Roma, San Marzano, or plum varieties have less water and richer flavor for sauces.
• Always Acidify: Acidify by adding an acid like lemon juice, citric acid or vinegar to the tomatoes to increase their acidity and ensure safety. Low-acid tomatoes need extra acidity for safe canning.
• Label Everything: Include date and type (whole, diced, sauce).
• Batch Plan: Work in 10–20 lb batches for efficiency.

How to Use Preserved Tomatoes in Fall Dishes

• Frozen whole/chopped: Add to stews, chili, or braises—no thaw needed.
• Frozen sauce: Instant base for lasagna, baked ziti, pizza, or shakshuka.
• Canned tomatoes: Use in any recipe calling for store-bought canned.
