How to Make Slow Cooker Cajun Potato Soup

Step 1: Brown the Sausage

Start the flavor journey by heating olive oil in a skillet over medium heat. Add the andouille sausage slices, letting them sizzle and caramelize for 3-4 minutes on each side. This step creates irresistible crispy edges and releases incredible smoky flavor, which will mingle deliciously with the soup’s rich broth later on. Once browned, transfer the pieces to a paper towel-lined plate to drain excess grease—it’s a simple trick for deeper flavor without extra oiliness.

Step 2: Add Everything to the Slow Cooker

Now for the “set it and forget it” magic! Toss your browned sausage, potatoes, bell pepper, onion, celery, carrots, minced garlic, Cajun seasoning, salt, and black pepper into your slow cooker. This aromatic pile-up of ingredients may look rustic, but it’s the foundation of Slow Cooker Cajun Potato Soup’s satisfyingly complex flavor.

Step 3: Pour Broth and Start Cooking

Pour the chicken broth over your assembled veggies and sausage, making sure everything is nicely combined. Cover and let the slow cooker work its charm: set it on high for 3 hours or low for 5 hours. This leisurely simmer allows potatoes to turn meltingly tender and the flavors to marry in true Southern style.

Step 4: Stir In the Milk

After the initial cooking time, it’s time to build that creamy base. Remove the slow cooker lid and stir in the milk. Return the lid and continue to cook on low for another hour, letting the creaminess infuse every spoonful without risking a curdle.

Step 5: Add Cream and Cheese

Almost there! Stir in the whipping cream and shredded cheddar cheese, then cover and cook for an additional 15 minutes until the cheese is totally melted and creates that dreamy, golden finish. The soup will be luscious, thick, and calling your name.

Step 6: Serve and Enjoy

Finally, ladle your Slow Cooker Cajun Potato Soup into bowls, then sprinkle with sliced green onions. Don’t forget a few dashes of Tabasco sauce if you like a little extra kick! Cozy, creamy, and full of personality, this soup is ready for the spotlight.

You can also toss on extra shredded cheddar for a cheesy crown, or even a dollop of sour cream for extra richness.

Make Ahead and Storage

Storing Leftovers

Got leftovers? Lucky you! Let the Slow Cooker Cajun Potato Soup cool to room temperature, then transfer it into airtight containers. It will keep in the fridge for up to 4 days. The flavors meld even more overnight, so don’t be surprised if you find it tastes even better the next day.

Freezing

This soup freezes beautifully, making future weeknight dinners a breeze. Allow the soup to cool completely before portioning it into freezer-safe containers or heavy-duty zip-top bags (leave a little space at the top for expansion). The potatoes can get a bit softer after freezing, but the flavor stays true. Enjoy within 2 months for peak enjoyment.

Reheating

To reheat, simply thaw frozen soup in the fridge overnight, or defrost gently in the microwave. Warm the soup on the stovetop over medium-low heat, stirring occasionally, until hot. If it seems a little thick after chilling, just stir in a splash of milk or broth and let it heat through until creamy and smooth once again.

FAQs

Can I make Slow Cooker Cajun Potato Soup vegetarian?

Absolutely! Swap the andouille sausage for a plant-based sausage or smoked tempeh, and use vegetable broth instead of chicken broth. You’ll still capture plenty of Cajun flavor, and the soup will be wonderfully hearty and satisfying.

Is Slow Cooker Cajun Potato Soup spicy?

The level of heat depends on your Cajun seasoning and sausage brand. If you’d prefer a milder soup, use a mild sausage and cut back on the Cajun seasoning. Want more kick? Add extra Tabasco or a pinch of cayenne when serving!

Can I use different potatoes?

Yes! Russet potatoes give the best creamy texture in Slow Cooker Cajun Potato Soup, but Yukon Gold or red potatoes work too. Just note that different varieties may result in slightly different textures, with waxier potatoes holding their shape a bit more.

How can I make the soup thicker?

If you love an ultra-thick, chowder-like potato soup, use a potato masher or immersion blender to mash some of the potatoes right in the slow cooker before adding the cream and cheese. This will give the soup a heftier, more rib-sticking body.

Can I prepare this ahead for a party?

You sure can! Prep all the veggies and sausage the night before and refrigerate. In the morning, dump everything into the slow cooker, set it, and by party time, you’ll have a big pot of Slow Cooker Cajun Potato Soup ready to wow your guests—just finish with the cream and cheese before serving.
