Homemade Canned Spaghetti Sauce
Total TimePrep: 1-1/2 hours + simmering Process: 40 min.
- 25 pounds tomatoes (about 80 medium)
- 4 large green peppers, seeded
- 4 large onions, cut into wedges
- 2 cans (12 ounces each) tomato paste
- 1/4 cup canola oil
- 2/3 cup sugar
- 1/4 cup salt
- 8 garlic cloves, minced
- 4 teaspoons dried oregano
- 2 teaspoons dried parsley flakes
- 2 teaspoons dried basil
- 2 teaspoons crushed red pepper flakes
- 2 teaspoons Worcestershire sauce

- In a Dutch oven, bring 2 quarts water to a boil. Using a slotted spoon, place tomatoes, one at a time, in boiling water for 30-60 seconds. Remove each tomato and immediately plunge into ice water. Peel and quarter tomatoes; place in a stockpot.
- Pulse green peppers and onions in batches in a food processor until finely chopped; transfer to stockpot. Stir in next 11 ingredients. Add water to cover; bring to a boil. Reduce heat; simmer, uncovered, 4-5 hours, stirring occasionally.
- Discard bay leaves. Add 2 tablespoons lemon juice to each of 9 hot 1-qt. jars. Ladle hot mixture into jars, leaving 1/2-in. headspace. Remove air bubbles and adjust headspace, if necessary, by adding hot mixture. Wipe rims. Center lids on jars; screw on bands until fingertip tight.
- Place jars into canner with simmering water, ensuring that they are completely covered with water. Bring to a boil; process for 40 minutes. Remove jars and cool.

Either I didn't simmer for long enough (6 hours) or the onions here in Texas are waaaaay big but I'm getting about 12 qts from this recipe. Should i be concerned?

This sounds like a great recipe. I've been making spaghetti sauce for years. If anyone is nervous about canning, you can always use containers and put in freezer or in seal-a-meal bags.

The best home canned spaghetti sauce recipe I have found. Not watery. I have also wondered if it should be pressure canned?

I agree with Lorriane. Everything I've read says use bottled lemon juice to assure acidity for safety. Also, have read that when using veggies such as peppers, sauce needs to be pressure canned, as this changes acididty too much to be safe for water bath. What does the test kitchen say?

Me again. A year later. Water canned sauce with oil stored in the cupboard was a massive success. Tasty tasty tasty. Two things I will do this year differently: 1) add less [read: way less] sugar,

I haven't tried the recipe BUT I have been canning a lot in recent years and everything I read states bottled lemon juice should be used. The acidity is constant in bottled juice whereas fresh not so much. The success of a canning recipe depends on the acidity...lemon or vinegar to insure safety. Spices can used per taste.

Just learning to can tomatoes. When directions call for completely covering jars with water in bath, but video shows only a few inches. Which is correct?

First time at canning. Do you store in pantry or refrigerate?

Is this a true tested recipe with this much oil in it? It’s my understanding that canning things made with lil in large quantities can cause botchulism.
