Ingredients for Slow Cooker Cajun Potato Soup

- Bell pepper: Adds a touch of sweetness and crunch to balance the spicy sausage.
- Onion: Provides a savory base flavor to the soup.
- Celery: Offers freshness and a subtle flavor that complements the other ingredients.
- Carrots: Bring a slight sweetness and vibrant color to the dish.
- Garlic: Infuses the soup with aromatic, savory depth.
- Cajun seasoning: The star of the recipe, giving the soup its signature spiciness and warmth.
- Chicken broth: Adds a flavorful liquid base for the soup.
- Milk: Contributes to the creamy texture of the soup.
- Heavy whipping cream: Takes the creaminess to the next level, making the soup rich and smooth.
- Cheddar cheese: Melts into the soup, adding a cheesy, comforting element.
- Green onions: For garnish, offering a fresh, tangy finish.
- Tabasco sauce: Adds an optional extra layer of heat and flavor when serving.
Alternative Ingredient Suggestions
• Chorizo sausage: If you want to kick up the spice even more, chorizo is a great alternative to andouille sausage.
• Yukon gold potatoes: These potatoes will break down more during cooking, creating an even thicker and creamier soup.
• Plant-based sausage or tofu: For a vegetarian version, try using plant-based sausage or pan-fried tofu for protein.
• Low-fat milk or cream: To make the soup lighter, substitute with low-fat milk or cream. Just keep in mind that the texture may be less rich.
Step-by-Step Instructions for Making Slow Cooker Cajun Potato Soup
- Brown the sausage: Heat the olive oil in a pan and brown the andouille sausage on both sides. This step enhances the flavor but can be skipped if you’re short on time.
- Prepare the slow cooker: Add the browned sausage, potatoes, bell pepper, onion, celery, carrots, garlic, and Cajun seasoning to the slow cooker.
- Add the liquids: Pour the chicken broth over the ingredients in the slow cooker and stir to combine.
- Slow cook: Cover and cook on high for 3 hours or on low for 5 hours, until the vegetables are tender.
- Finish the soup: Stir in the milk and continue cooking for another hour.
- Add cream and cheese: Pour in the heavy cream and shredded cheddar cheese, and cook for 15 minutes, or until the cheese melts and the soup becomes creamy.
- Serve and garnish: Ladle the soup into bowls and top with green onions and a splash of Tabasco sauce for an added kick.

Tips & Tricks for the Best Cajun Potato Soup
- Browning the sausage: Browning the sausage before adding it to the slow cooker enhances the depth of flavor. If you’re pressed for time, feel free to skip this step and add the sausage directly to the slow cooker.
- Adjust the spice: Start with the recommended amount of Cajun seasoning and taste the soup before serving. If you prefer a milder flavor, use less seasoning or opt for a milder Cajun blend.
- Thicken the soup: To make the soup even thicker, mash a portion of the potatoes before adding the milk and cream. Alternatively, you can use a cornstarch slurry or a roux to thicken it further.
- Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 5 days. Reheat gently on the stove or in the microwave, adding a bit of extra milk or cream to restore creaminess.
Pairing Ideas and Variations
This Slow Cooker Cajun Potato Soup pairs wonderfully with crusty bread, cornbread, or garlic bread. For a complete meal, serve it alongside a fresh green salad, such as a Cajun Honey Jalapeno Slaw or a Fresh Chopped Vegetable Salad. If you want to add variety to the recipe, consider trying the following variations:
• Chicken Cajun Potato Soup: Replace the sausage with shredded cooked chicken for a lighter protein option.
• Seafood Cajun Potato Soup: For a twist, add cooked shrimp during the last hour of cooking.
• Vegan Cajun Potato Soup: Use plant-based sausage or tofu instead of the sausage, and substitute the dairy ingredients with coconut milk and vegan cheese.
Make-Ahead and Freezing Tips
This soup is perfect for making ahead of time. Prepare the soup up until the point of adding the milk and cream, then cool and refrigerate.
