Crockpot Marinara Sauce


This easy Crockpot Marinara Sauce recipe cooks all day for superb slow simmered flavor - with only four ingredients!

Prep Time: 15 minutes

Cook Time: 8 hours

Total Time: 8 hours, 15 minutes

Yield: 6-8 servings


  • 2 onions, chopped
  • 8 cloves garlic, minced
  • 2 Tbsp. olive oil
  • 4 (14 oz.) cans diced tomatoes with Italian seasoning, undrained
  • 6 oz. can tomato paste
  • 1/2 cup water
  • 2 tsp. dried Italian seasoning
  • Salt and pepper to taste


Place onions, garlic, and olive oil in medium microwave-safe bowl. Microwave on high for 2-3 minutes, stirring once during cooking time, until the onion is softened.

If you have a new hotter cooking crockpot, check the sauce after 6 or 7 hours.
