Ingredients
For the Soup Base:
6 cups (about 2 lbs) russet potatoes, peeled and diced into 1/2-inch cubes
1 (12-14 oz) package Andouille sausage, sliced into rounds (smoked sausage or kielbasa work too)
1 large yellow onion, diced
1 large green bell pepper, diced
3 celery stalks, diced
4 cloves garlic, minced
4 cups (32 oz) low-sodium chicken broth
1 (10 oz) can diced tomatoes with green chilies (like Rotel), undrained
2 tablespoons Cajun seasoning blend (adjust for heat preference)
1 teaspoon dried thyme
1 bay leaf
Salt and freshly ground black pepper to taste
For the Creamy Finish:
1 cup heavy cream or full-fat coconut milk (for dairy-free)
8 oz cream cheese, softened and cubed
1 cup shredded sharp cheddar cheese (optional, for extra richness)
For Garnish (Optional but Recommended):
Sliced green onions
Chopped fresh parsley
Extra shredded cheddar cheese
Hot sauce or a sprinkle of extra Cajun seasoning
Instructions
Step 1: The Prep (15 minutes)
Prepare the Vegetables: Peel and dice the potatoes, onion, bell pepper, and celery. Mince the garlic. The uniform dicing ensures even cooking.
Brown the Sausage (Optional but Recommended): For deeper flavor, heat a skillet over medium-high heat. Add the sliced Andouille sausage and cook for 4-5 minutes until lightly browned. This step adds a wonderful caramelized note but can be skipped for a truly dump-and-go meal.
Combine in the Slow Cooker: In the bowl of your 6-quart or larger slow cooker, add the diced potatoes, sausage (browned or raw), onion, bell pepper, celery, and garlic. Pour in the chicken broth and the undrained can of diced tomatoes with green chilies.
Step 2: The Long Simmer (6-8 hours on LOW)
Season: Add the Cajun seasoning, dried thyme, and bay leaf. Stir everything well to combine.
Cook: Cover and cook on LOW for 6-8 hours or on HIGH for 3-4 hours, until the potatoes are extremely tender and easily pierced with a fork.
Step 3: The Creamy Finish (5 minutes)
Thicken the Soup: About 30 minutes before serving, remove the bay leaf. Use a potato masher or the back of a large spoon to mash about one-third of the potatoes directly in the slow cooker pot. This will naturally thicken the soup.
Add Creaminess: Turn the slow cooker to the WARM or HIGH setting. Add the cubed cream cheese and heavy cream. Stir continuously until the cream cheese is fully melted and incorporated into the soup.
Add Cheese (Optional): If using, stir in the shredded cheddar cheese until melted.
Final Seasoning: Taste and adjust seasoning, adding salt, pepper, or an extra pinch of Cajun seasoning if desired.
Step 4: Serve & Savor
Ladle the hot, creamy soup into deep bowls. Garnish generously with sliced green onions, fresh parsley, and an extra sprinkle of cheese if you like. Serve with crusty bread, garlic toast, or cornbread for dipping.
Recipe Notes & Tips
Spice Level Control: Cajun seasoning blends vary in heat. Start with 2 tablespoons for a medium kick. You can always add more at the end. For a milder soup, use a “salt-free” Cajun blend and add salt to taste.
Make it Heartier: Stir in 1 cup of frozen sweet corn with the vegetables or a can of drained and rinsed red kidney beans during the last hour of cooking.
Vegetarian Version: Omit the sausage, use vegetable broth, and add 1 cup of rinsed brown lentils at the beginning for protein. Consider adding 1 teaspoon of smoked paprika to mimic the smoky flavor.
Storing & Reheating: Store cooled soup in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stovetop over medium-low heat, stirring frequently, as the creamy base can separate if boiled. Add a splash of broth or milk if it’s too thick.
Freezing: Freeze for up to 3 months, though the texture of the potatoes and cream may change slightly. Thaw overnight in the fridge and reheat gently.
