Canning Tomato Sauce

20 pounds of fresh tomatoes

1 cup chopped onions

8 cloves of minced garlic

1 Tablespoons of oil

Lemon Juice

Canning salt


1. Wash tomatoes and cut into quarter pieces. Place the tomatoes into a large sauce pan.

2. Add oil to a fry pan and heat. Add chopped onions and garlic and cook for several minutes until they are transparent.



3. Add the cooked onions and garlic to the pot of tomatoes.



4. Turn on the heat and simmer the tomatoes 20 minutes.

Stir occasionally to keep the bottom from burning.

5. Puree tomato sauce with a food processor or use a food mill. Strain puree to remove the tomato peels and seeds.


6. Put the pureed sauce back into a sauce pan and bring to a simmer.

Keep heat low and simmer until the tomato sauce is reduced by half.


7. Ladle the reduced tomato sauce into pint or half pint mason jars leaving 1 inch head space. Add 1 tablespoon of lemon juice to each pint and ½ teaspoon of salt to each pint. (Adding salt is optional)



8. Wipe off the rims of your bottles with a clean cloth. Add the two piece lids and tighten by hand.

9. Place the tomato sauce into a water bath canner. Follow instructions on using a water bath canner.

10. When the water begins to boil, process 35 minutes if you live at or below sea level (1000 ft). Adjust your processing time by adding minutes according to your altitude. Use the chart below for times needed in your area.

11. When the processing time is up, lift lid on the canner and carefully remove tomato sauce with a bottle lifter. Set hot bottles on a clean towel on the counter. Let bottles cool for 12 to 24 hours.

12. When the jars of sauce are cooled. Check the seals. Press on the center of each bottle. Lids should not flex. If any of the bottles do not seal, place unsealed jars in the refrigerator and use within a week.

Unsealed bottles of canning tomato sauce can be reprocessed. Remove lids and wipe rims to make sure there are no food particles on the rims. Place new lids on bottles, tighten rings and reprocess.
