Ingredients Equipment Method Notes

Ingredients
  

  • 2 tbsp Unsalted Butter
  • 14 oz Andouille Sausage sliced into 1/4-inch rounds
  • 1 large Yellow Onion diced
  • 2 stalks Celery diced
  • 1 large Green Bell Pepper diced
  • 4 cloves Garlic minced
  • 2.5 lbs Russet Potatoes peeled and cubed into 1-inch pieces
  • 6 cups Low-Sodium Chicken Broth
  • 2 tbsp Cajun Seasoning plus more to taste
  • 1 cup Heavy Cream
  • Optional garnishes: shredded cheddar cheese, sliced green onions or chives

Equipment

  • 1 Large Dutch oven or pot
  • 1 Immersion Blender or Regular Blender

Method
 

  1. Melt butter in a large Dutch oven over medium-high heat. Add the sliced Andouille sausage and cook until browned, about 5-7 minutes. Remove with a slotted spoon and set aside, leaving the rendered fat in the pot.
  2. Add the diced onion, celery, and bell pepper to the pot. Sauté for 6-8 minutes until softened. Add the minced garlic and cook for 1 more minute until fragrant.
  3. Stir in the chicken broth, Cajun seasoning, and cubed potatoes. Bring to a boil, then reduce heat, cover, and simmer for 15-20 minutes until potatoes are tender.
  4. Use an immersion blender to partially blend the soup until it's creamy but still has some potato chunks. Alternatively, blend about 1/3 of the soup in a regular blender and return it to the pot.
  5. Stir the cooked sausage back into the pot along with the heavy cream. Heat through for 5 minutes without boiling. Taste and adjust seasoning. Serve hot, garnished as desired.

Notes

Spice Level: Adjust the amount of Cajun seasoning to your preference. Start with less if you are sensitive to heat.
Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days.
