  • Large pot
  • High-speed blender
  • 6 qt. slow cooker


Vegetable Puree

  • 2 cups sweet potatoes peeled and chopped ($0.72)
  • 2 cups carrots peeled and chopped ($0.12)
  • 3 cups cauliflower florets ($1.44)
  • 3 cups red bell pepper chopped ($2.96)
  • 1/2 cup extra virgin olive oil ($1.52)
  • 1/3 cup unsweetened non-dairy milk ($0.20)

Tomato Sauce Ingredients

  • 3 (14.5 ounce) cans diced tomatoes ($3.18)
  • 1 (14.5 ounce) can tomato sauce ($1.06)
  • 3 (6 ounce) cans tomato paste ($2.82)
  • 2 cups water
  • 1/2 yellow onion diced ($0.30)
  • 4 large cloves garlic minced ($0.24)
  • 1 tablespoon low sodium vegetable bouillon base ($0.27)
  • 1 tablespoon Italian seasoning ($0.18)
  • 1/2 teaspoon black pepper ($0.02)
  • 2 bay leaves ($0.24)


  • Make the vegetable puree. Add the chopped sweet potatoes, carrots, cauliflower, and red bell pepper to a large pot and fill with water. Bring to a boil over medium heat and cook until the vegetables are fork tender, about 10-15 minutes. Once tender, drain the vegetables and transfer to a high-speed blender. Add the olive oil and milk and blend until smooth.
  • Put all ingredients in a slow cooker bowl. Stir to combine and cook on low for 8 hours. The color should go from orange to a deep red during the cooking process.
  • Serve or store. Enjoy immediately over pasta or allow to cool and store in mason jars in the refrigerator for up to 4 days or in the freezer for up to 3 months. This recipe makes 5 (24 ounce) jars of sauce.
