Step‑by‑Step Instructions for Slow Cooker Cajun Potato Soup
Step 1: Brown the Sausage
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add sliced andouille sausage and cook for 4-5 minutes, allowing it to brown nicely on both sides. This step creates depth of flavor, providing a rich base for your Slow Cooker Cajun Potato Soup.
Step 2: Layer the Ingredients
Transfer the browned sausage into the slow cooker, ensuring to scrape up any flavorful bits from the skillet. Add diced russet potatoes followed by chopped bell pepper, onion, celery, carrots, and minced garlic. Sprinkle in Cajun seasoning, salt, and pepper for an aromatic kick before smoothing everything into an even layer.
Step 3: Add the Broth
Pour in enough chicken broth to cover all the ingredients, usually about 4-6 cups depending on your slow cooker size. Stir gently to combine all the components, ensuring that the seasoning is distributed throughout the mixture. This will form the savory base for your hearty Soup.
Step 4: Slow Cook the Soup
Cover the slow cooker and set it to cook on high for 3 hours or on low for 5 hours. You’ll know it’s done when the potatoes are tender and easily pierced with a fork. This slow cooking method will meld the flavors beautifully while you go about your day.
Step 5: Incorporate Dairy
Once the initial cooking time is completed, stir in 1 cup of milk for a creamy texture. If you’re using a dairy-free option, this is the moment to incorporate your chosen alternative. Cook on low heat for an additional hour, allowing the flavors to blend seamlessly with the creaminess.
Step 6: Finish the Soup
After the extra hour of cooking, add ½ cup of whipping cream and 1 cup of shredded cheddar cheese into the slow cooker. Stir continuously over low heat until the cheese melts completely and the soup becomes beautifully creamy. Allow this to simmer for another 15 minutes for the flavors to infuse.
Step 7: Serve and Garnish
Ladle the rich Slow Cooker Cajun Potato Soup into bowls, adding a sprinkle of sliced green onions on top for freshness. If you crave a bit more heat, drizzle a dash of Tabasco sauce over each serving. Enjoy this heartwarming meal with crusty bread or cornbread on the side!

Make Ahead Options
This Slow Cooker Cajun Potato Soup is a fantastic choice for busy home cooks looking to meal prep without sacrificing flavor! You can chop all your vegetables and sausage and store them in the refrigerator for up to 24 hours before cooking. Just combine them in the slow cooker with the seasonings and broth when you’re ready to enjoy. If you prefer, you can prepare the entire soup base and refrigerate it for up to 3 days; simply hold back on adding dairy ingredients until you’re ready to serve to maintain creaminess. When reheating, add the milk and cream as needed to ensure the soup remains just as delicious as the day it was made. Enjoy the convenience of a heartwarming meal with minimal effort!

Slow Cooker Cajun Potato Soup Recipe FAQs
What type of potatoes should I use for the best results?
Absolutely! For the best texture, I recommend using russet potatoes since they provide a creamy base and help thicken the soup. However, you can also swap them for sweet potatoes for a hint of sweetness or use Yukon Gold potatoes for a buttery flavor.
How should I store leftover Slow Cooker Cajun Potato Soup?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. When reheating, do so gently on the stove or in the microwave until heated through. If you notice any dark spots or off smells, it’s best to discard it.
Can I freeze Cajun Potato Soup, and if so, how?
Yes! You can freeze the soup for up to 3 months. However, it’s important to leave out the dairy components (like milk and cream) before freezing. To freeze, let the soup cool completely, then pour it into a freezer-safe container, leaving some space at the top for expansion. When ready to enjoy, thaw in the fridge overnight and reheat, adding fresh milk and cream to restore the creamy consistency.
What if my soup turns out too salty?
If you find that your soup is too salty, you can balance it out by adding an extra diced potato to absorb some saltiness. Let it cook for an additional 20-30 minutes until the potato softens. If that doesn’t help, consider adding a splash of unsalted broth or water to dilute the flavors.
Are there any dietary considerations for this recipe?
Definitely! This Slow Cooker Cajun Potato Soup can be easily customized for dietary needs. For a gluten-free version, use certified gluten-free broth and check all pre-packaged ingredients for hidden gluten. You can also make it vegetarian by swapping the andouille sausage for plant-based sausage and using vegetable broth instead of chicken broth. Always check for allergies related to specific ingredients, especially the Cajun seasoning.
How can I adjust the spiciness of the soup?
You can modify the spiciness by adjusting the amount of Cajun seasoning you add. Start with a smaller amount and gradually increase it to your preferred heat level. If you want it even milder, use a mild sausage or omit the Tabasco sauce. Enjoy experimenting to find your perfect balance of flavors!
