Ingredients

  • 2 carrots diced
  • 1 medium yellow onion chopped
  • 4 cloves garlic minced
  • ¼ cup basil pesto
  • ¼–½ teaspoon dried red pepper flakes

Instructions

  • Prep the vegetables by chopping the carrots and onion, and mincing the garlic cloves.
    2 carrots, 1 medium yellow onion, 4 cloves garlic
  • Add the chopped vegetables to a large slow cooker along with pesto, red pepper flakes, and chicken broth. Cover tightly with lid and cook on LOW for 6-8 hours or on HIGH for 3-4 hours.
    ¼ cup basil pesto, ¼–½ teaspoon dried red pepper flakes, 8 cups chicken broth
  • Remove lid and add in sweet Italian sausage, breaking it up into small bite-size chunks. Stir in kale, rinsed and drained cannellini beans, and lemon juice and zest. 
    30 ounces cannellini beans, rinsed and drained (or Great Northern or Navy beans), 1 pound mild Italian sausage, 1 bunch kale, 3 Tablespoons fresh lemon juice + 1 tablespoon lemon zest
  • Cover again and cook on high for another 30-45 minutes until sausage is cooked through and soup is hot.

Notes

  • Cannellini, Great Northern, or Navy beans all work well in this soup.
  • Add the sausage directly to the broth to keep prep simple.
  • Spinach can replace kale; add it at the end so it doesn’t overcook.
  • A small splash of lemon at the end brightens the whole pot.
  • Add a Parmesan rind to the slow cooker for a deeper, savory flavor.
Storage:
  • Store leftovers in the fridge for 3 days or freeze for up to 3 months.
  • Reheat on the stove with a little broth if the soup thickens.
