Not having time to can my tomatoes this year so I've recently found a way to preserve them and I am very pleased with my results ...
Wash tomatoes in water
Remove any bad spots and the core
Slice into quarters or smaller depending on size of tomato
Lay on a sheet pan in single rows and fill pan
Drizzle with Olive Oil
Sprinkle with dried garlic, fresh chopped garlic or garlic powder
Salt and Pepper to your taste
Sprinkle with either dried or fresh Oregano and Basil
May also add slices of green pepper or hot pepper if you prefer
Roast in 350 degree oven for an hour and a half
(May need to adjust roasting time depending on sweetness of
your tomatoes as they do have some sugar content and will burn)
Remove from oven and put into clean canning jars.
Filling to recommended fill line for freezing.
Add cleaned lids and rings,
Mark date and contents and put into your freezer.
Pull jars out of freezer and allow to thaw when you need.
Can be used as is in soups, stews, sauces, pizza, salsas, chilli's, etc.
Put into blender and blend if you want a puree type sauce.
I used various sizes of canning jars for different needs.
