Chop the Tomatoes. Cut peeled tomatoes into chunks. Pulse in a food processor until chopped but not puréed. Transfer each processed batch into a 7–8 quart nonreactive pot (stainless steel or enameled).
Add: brown sugar, salt, balsamic, black pepper, crushed red pepper (add minced garlic if using)
Bring to a boil, then reduce heat and simmer uncovered for 70–90 minutes, stirring occasionally, until the sauce reduces and thickens. (If using watery tomatoes, let it go longer.)
Remove from heat and stir in:
basil, parsley, cilantro, oregano... (add roasted garlic if using)
To Freeze This Sauce:
Ladle cooled sauce into freezer-safe mason jars or containers. Leave room at the top for expansion. Freeze for up to 6 months.
Canning This Sauce (Safely and Easily):
One of my favorite things about this recipe is that it cans beautifully… as long as you follow proper acidity guidelines. Because tomatoes vary in acidity, you must add bottled lemon juice to each jar for safe water-bath canning. Bottled lemon juice is standardized, fresh lemon juice is not.
Once that’s in place, this sauce is a perfect beginner-friendly canning project.
Jar Size Options:
Pints (great for smaller serving size, pizza, or dipping sauce)
Quarts (ideal for spaghetti, chili, lasagna, and soup)
I usually make 2-4 batches to can. If I make 1 batch, I will either use at once or freeze leftover sauce.
*To peel tomatoes: Score an “X” on the bottom, drop into boiling water for 30 seconds, then move to ice water. Skins slide off. BONUS – You can bake the skins with some oil and salt, until dried, and eat like chips or grind up for powder for smoothies or sauces.
