Ingredients
- 1 tablespoon olive oil
- 1 13.5 ounce package andouille sausage, sliced into 1/4-inch rounds
- 4 russet potatoes, peeled and cut into bite-sized pieces
- 1 cup diced bell pepper (red or green)
- 1 cup diced onion
- 1/2 cup diced celery
- 1/2 cup sliced carrots
- 1 tablespoon minced garlic
- 1 tablespoon Cajun seasoning
- 1 teaspoon salt
- 1 teaspoon black pepper
- 3 cups chicken broth
- 1 cup milk
- 1/2 cup whipping cream
- 1 cup shredded cheddar cheese
- Green onions, sliced for serving
- Tabasco sauce, for serving
Instructions
- Step 1: Heat the olive oil in a pan over medium heat and brown the andouille sausage slices on both sides until they develop a nice color. This adds flavor to the soup.
- Step 2: Transfer the browned sausage to the slow cooker. Add the potatoes, diced bell pepper, onion, celery, carrots, minced garlic, Cajun seasoning, salt, and black pepper.
- Step 3: Pour the chicken broth over the ingredients in the slow cooker and stir gently to combine. Cover and cook on high for 3 hours or on low for 5 hours.
- Step 4: After the initial cooking time, stir in the milk and continue to cook for an additional hour to meld the flavors and soften the potatoes.
- Step 5: Add the whipping cream and shredded cheddar cheese to the soup. Cook until the cheese melts, about 15 minutes, stirring occasionally to combine.
- Step 6: Serve the soup warm, topped with sliced green onions and a dash of Tabasco sauce for a spicy kick.
Tips & Variations
- For a thicker soup, mash some of the potatoes directly in the slow cooker before adding the cream and cheese.
- Substitute smoked sausage or kielbasa if andouille is unavailable.
- Add a can of corn or diced tomatoes for extra texture and flavor.
- Adjust the Cajun seasoning and Tabasco sauce to control the spice level to your liking.
Storage
Store leftover soup in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove or in the microwave, stirring occasionally. If the soup thickens on standing, add a splash of milk or broth while reheating to loosen it up.
