Slow Cooker Marinara Sauce Recipe

A marinara sauce made in a slow cooker that is spiced just right can’t be beat. The fact that you can make it and take advantage of a slow cooker and walk away after you out in ingredients is a real prize. It’s great on pasta, rice, you can add it to a soups and stews, pour over meatballs or freeze it for later.

This recipe yield 5 cups and I recommend you make a bigger batch than this..because you’ll go through 5 jars pretty quick.

Slow Cooker Marinara Sauce Recipe


  • 1 (28 ounce) can diced tomatoes

  1. Put ingredients in a slow cooker and cook on low for 8 hrs. 
  2. Remove bay leaves and stir well.


note to yourself:

  1. instead of canned tomatoes you can also use fresh ones,
  2. will keep in freezer for 3 months and 3 -4 days in a fridge,
  3. there’s little tomato chunks left, if you want to have it absolutely smooth let the sauce cool down and then blend it with either a counter top blender or a immersion blender.
