Slow Cooker Marinara Sauce #Recipe

This slow cooker marinara sauce is easily my youngest son’s favorite dinner.  This sauce is full of flavor, packed with vegetables, and incredibly easy as well.  I literally toss everything into the slow cooker and walk away until just before dinner when I remove the bay leaf, puree, and serve over pasta.

  • 2 Cans Whole Peeled Tomatoes (28 oz each)
  • 1 Can Tomato Paste (6 oz)
  • 1/2 tsp Italian Seasoning (or to taste)
  • 1/2 tsp Tony's Cajun Creole Seasoning (or to taste)(you can substitute your favorite Go To seasoning)
  • 1 TBSP Minced Garlic
  • 1/2 Cup Frozen Onion & Bell Pepper Medley
  • 1/2 Cup Chopped Carrots
  • 1/2 Cup Chopped Celery (Include celery leaves for more flavor)
  • 1 tsp Sugar
  • 1/4 tsp Red Pepper Flakes
  • 1 Bay Leaf


  • Toss all ingredients into your slow cooker.
  • Cook on low for 4-6 hours.
  • Find the bay leaf and remove it before pureeing.
  • Puree the remaining ingredients. I use an immersion blender, but a blender or food processor should work fine.
