  • 3 medium-size Russet potatoes, peeled and cubed (about 2 cups)
  • 1 large carrot, peeled and sliced into 1/4-inch slices
  • 4 cups Andouille sausages, sliced into 1/2-inch pieces, sautéed until lightly browned
  • 3 cups quality vegetable broth
  • 1 cup yellow onion, finely diced
  • 4 tsp minced garlic (about 8 cloves)
  • 1/2 tsp garlic salt
  • 1 medium stalk of celery, roughly chopped (about 1/2 cup)
  • 1/2 tsp quality onion powder
  • 2 cups cold whole milk (plant-based milk can be used as an alternative)
  • 2 tbsp cornstarch (arrowroot powder as an alternative)
  • 2 cups mature Cheddar cheese, finely grated
  • 1/2 tsp freshly ground black pepper (about 20 rotations of a pepper mill)


  1. Prepare the Ingredients: Begin by peeling and cubing the potatoes, slicing the carrot, chopping the onion and celery, and mincing the garlic. Slice and sauté the Andouille sausages until they are lightly browned.
  2. Combine in Slow Cooker: Place the potatoes, carrot, browned sausages, onion, garlic, celery, and garlic salt into the slow cooker. Pour in the vegetable broth and stir to combine.
  3. Cook: Set your slow cooker to low and cook for 6-8 hours, or on high for 3-4 hours, until the potatoes are tender and the flavors have melded together.
  4. Prepare the Cheese Mixture: About 30 minutes before serving, mix the cornstarch with the cold milk until smooth. Pour this mixture into the slow cooker. Add the grated Cheddar cheese and stir until the cheese has melted and the soup has thickened. Season with onion powder and freshly ground black pepper.
  5. Serve Warm: Once the soup is thickened and heated through, give it a final taste and adjust seasoning as needed. Serve hot, garnished with additional grated cheese or fresh herbs if desired.
