Ingredients

Scale
  • 2 tablespoons unsalted butter
  • 1 large yellow onion, diced
  • 2 celery stalks, diced
  • 4 garlic cloves, minced
  • 3 tablespoons all-purpose flour (or 1.5 tablespoons cornstarch for gluten-free)
  • 5 cups chicken broth (low-sodium preferred)
  • 1 cup heavy cream (or half-and-half/whole milk for lighter version)
  • 4 medium Yukon Gold potatoes (about 1.5 lbs), diced
  • 12 oz andouille sausage, sliced into 1/4-inch rounds
  • 1.5 cups shredded cheddar cheese
  • 6 slices cooked bacon, crispy and crumbled
  • 2 tablespoons Cajun seasoning
  • 1/2 teaspoon dried thyme (optional)
  • Salt & freshly ground black pepper, to taste
  • Fresh chives or green onions, sliced (for garnish)
  • Extra cheddar and bacon (for garnish)

Instructions

  1. Prep all ingredients: dice potatoes, onion, and celery; mince garlic; slice sausage; shred cheese; cook and crumble bacon.
  2. Heat a large soup pot or Dutch oven over medium heat. Add bacon and cook until crispy, about 6-8 minutes. Remove with a slotted spoon and set aside.
  3. Add sausage to the pot (leave about 1 tablespoon bacon fat) and brown for 3-4 minutes. Remove and set aside with bacon.
  4. Add butter to the pot. Sauté onion and celery for about 3 minutes until softened. Stir in garlic and cook for 1 minute more.
  5. Sprinkle flour over the veggies and stir constantly for 1-2 minutes until golden and no longer raw-smelling.
  6. Slowly pour in chicken broth, stirring to combine. Add diced potatoes, Cajun seasoning, thyme, salt, and pepper. Scrape up any browned bits from the bottom.
  7. Bring to a gentle boil, then reduce heat to medium-low. Simmer uncovered for 15-18 minutes, or until potatoes are fork-tender. Mash some potatoes for a creamier texture if desired.
  8. Lower the heat. Stir in heavy cream, browned sausage, and half the bacon. Simmer gently for 2-3 minutes to warm through.
  9. Gradually add shredded cheddar, stirring until melted and smooth. Taste and adjust seasoning as needed.
  10. Ladle soup into bowls. Top with remaining bacon, extra cheddar, and fresh chives or green onions. Serve hot with crusty bread or cornbread.

Notes

For gluten-free, use cornstarch or a gluten-free flour blend. Adjust Cajun seasoning for spice preference. Add extra veggies like carrots, bell peppers, or spinach for variety. Soup thickens as it sits; add broth or milk when reheating. For dairy-free, use coconut cream and vegan cheese. Freezes well for up to 2 months.
