I used to buy canned sauce, because it was easy and I honestly never even thought about making my own. Then I tried it. Tweaked it. And haven't looked back since. It is delicious and I use the base recipe as tomato soup. I do not measure most of the ingredients mainly because I go by taste. My kids prefer a sweeter sauce.
What you need:
1/2 yellow onion diced
2-3 cloves garlic minced
1 16 oz can diced Italian tomatoes
1 24 oz can tomato sauce
1 tbsp tomato paste
1/3 cup water
Salt/pepper to taste
1 tbsp dried parsley
2-3 tbsp brown sugar
1/4 tsp cinnamon
What you do:
sweat onions until translucent in some olive oil. Add in garlic. Cook about a minute and then add in tomatoes, tomato sauce, and paste. Add in water, salt, pepper, parsley, sugar, and cinnamon. Bring to a boil. Reduce heat and cover. Cook for about 25 minutes.
You can add in ground sausage or beef. Or pour over meatballs. The base recipe is Eventing except the sugar and cinnamon. You can also use the base recipe for minestrone soup, which is what I am going to try. Just add in a bit more water. You can make a double batch and freeze a portion to have on hand. It will last for months and then you will always have sauce on hand for busy weeknights!
