Ingredients

Scale
  • 2 pounds russet potatoes, peeled and diced small
  • 12 ounces andouille sausage, sliced into half-moons
  • 6 slices thick-cut bacon, chopped
  • 1 large yellow onion (or 2 medium), diced
  • 2 celery stalks, diced
  • 1 large red bell pepper, diced
  • 4 cloves garlic, minced
  • 4 cups low-sodium chicken broth
  • 1 cup heavy cream
  • 2 tablespoons Cajun seasoning (or to taste)
  • Salt and black pepper, to taste
  • 2 tablespoons unsalted butter
  • Fresh parsley or green onions, for garnish (optional)
  • Shredded cheddar cheese, for serving (optional)

Instructions

  1. Prep all ingredients: chop bacon, slice sausage, dice potatoes, onion, celery, and bell pepper, and mince garlic. Measure out broth and cream.
  2. Heat a large Dutch oven or soup pot over medium heat. Add chopped bacon and cook, stirring often, until crisp and golden brown (about 8 minutes). Remove bacon with a slotted spoon and set aside. Pour off all but 1 tablespoon of bacon fat.
  3. Add sausage slices to the pot. Sauté until browned and some fat renders out (about 5 minutes). Remove sausage and set aside with bacon. Add a bit of butter if the pot looks dry.
  4. Melt 2 tablespoons unsalted butter in the pot. Add onion, celery, and bell pepper. Cook, stirring and scraping up browned bits, until soft and fragrant (about 6 minutes). Stir in garlic and cook 1 minute more.
  5. Add diced potatoes, Cajun seasoning, salt, and black pepper. Pour in chicken broth, scraping the bottom for any stuck-on flavor. Bring to a gentle boil, then reduce heat and simmer until potatoes are very tender, about 15-20 minutes.
  6. Use an immersion blender to puree about half the soup directly in the pot, leaving a mix of creamy base and hearty chunks. (If using a blender, work in batches and be careful with hot liquid.)
  7. Pour in the heavy cream and return bacon and sausage to the pot, reserving a little for topping. Simmer gently for 5 more minutes to let flavors meld. Adjust seasoning as needed. If soup is too thick, add a splash of broth or milk.
  8. Ladle hot soup into bowls. Top with reserved bacon and sausage, fresh parsley or green onions, and shredded cheddar cheese if desired.

Notes

For a vegetarian version, skip the bacon and sausage, use vegetable broth, and add smoked paprika plus a pinch of liquid smoke. Adjust Cajun seasoning to control spice. Soup thickens as it sits; thin with broth or milk when reheating. Save some bacon and sausage for topping to keep them crispy. Can be made ahead and reheated; flavors deepen overnight.
