Ingredients

  • 12 oz andouille sausage, sliced (optional; see temps)
  • 2 Tbsp unsalted butter (or olive oil)
  • 1 medium yellow onion, diced
  • 2 ribs celery, diced
  • 1 green bell pepper, diced
  • 3 cloves garlic, minced
  • 2 lb potatoes (Yukon Gold or russet), peeled and ½-inch diced
  • 4 cups low-sodium chicken or vegetable broth
  • 1 cup whole milk
  • 1 cup half-and-half (or 12 oz evaporated milk)
  • 1½–2 tsp Cajun seasoning, to taste
  • 1 bay leaf
  • ¾–1 tsp kosher salt, to taste
  • ½ tsp black pepper
  • Hot sauce or cayenne, to taste
  • 1 cup shredded cheddar or pepper jack (optional, for serving)
  • 2–3 green onions or chives, thinly sliced (for serving)
  • Cooked bacon bits and chopped parsley (optional)

Equipment

  • Dutch oven or soup pot (5–6 qt)
  • potato masher
  • immersion blender optional, for creamier texture
  • cutting board
  • chef's knife
  • measuring cups
  • measuring spoons

Method

  • In a large pot over medium heat, brown andouille 3–4 minutes; remove to a plate (cook raw pork/beef andouille to 160°F; poultry to 165°F).
  • Add butter/oil. Sauté onion, celery, and bell pepper with a pinch of salt 5–6 minutes until soft. Stir in garlic 30 seconds.
  • Add potatoes, broth, Cajun seasoning, bay leaf, salt, and pepper. Bring to a boil; reduce to a simmer 12–15 minutes until tender.
  • Mash part of the potatoes to thicken (or brief immersion-blend).
  • Stir in milk and half-and-half; keep below a simmer. Return sausage to the pot. Adjust seasoning and heat with cayenne or hot sauce.
  • Serve with cheese, green onion, bacon, and parsley.
