Let the slow cooker do all the work for you when you make this big batch of freezer-friendly homemade spaghetti sauce.
Instructions
1
Dice the onion and mince the garlic. Place both in a 3 quart or larger slow cooker.
2
Add the crushed tomatoes, tomato paste, basil, oregano, brown sugar, balsamic vinegar, and butter to the slow cooker. Stir everything together well.
3
Place the lid on the slow cooker and cook on high for four hours or low for eight hours.

After cooking, give it a good stir, then add salt to taste. Start with just ½ tsp of salt and add more if needed (I added 1 tsp). Use the sauce immediately, refrigerate, or freeze for later.
