Step-by-Step Instructions
-
Sauté the Sausage:
Heat olive oil in a skillet over medium heat. Add the sliced andouille sausage and cook for about 5 minutes, stirring occasionally, until beautifully browned. Transfer the sausage to your crockpot. -
Add the Vegetables:
To the crockpot, add the chopped potatoes, bell pepper, onion, celery, carrots, and minced garlic. These vegetables will slowly soften and absorb all the Cajun flavors. -
Season Generously:
Sprinkle in the Cajun seasoning, salt, and black pepper. Pour in the chicken broth and stir well to combine everything evenly. -
Slow Cook to Perfection:
Cover and cook on LOW for 6–8 hours or HIGH for 3–4 hours, until the potatoes are fork-tender. -
Make It Creamy:
Once the potatoes are cooked, stir in the milk, whipping cream, and shredded cheddar cheese. Cover and cook for another 15–20 minutes until the cheese is fully melted and the soup is silky smooth. -
Serve & Garnish:
Ladle into bowls and top with sliced green onions. Serve with Tabasco sauce on the side for customizable heat.
