What You’ll Need for This Spicy Crockpot Soup

Before you start this delicious Cajun potato soup, gather your ingredients and prep your veggies. I always recommend using fresh andouille sausage for the most authentic flavor, though turkey andouille works beautifully if you prefer a lighter option. You’ll need a 6-quart slow cooker for this recipe.

• 1 package (13.5 ounces) andouille sausage, sliced into rounds
• 4 russet potatoes, peeled and diced into 1-inch cubes
• 1 cup onion, diced
• 1 cup bell pepper (red or green), diced
• ½ cup carrots, diced
• ½ cup celery, diced
• 1 tablespoon garlic, minced
• 3 cups chicken broth (I prefer low-sodium so I can control the salt)
• 1 tablespoon Cajun seasoning (adjust based on your heat preference)
• 1 teaspoon salt
• 1 teaspoon black pepper
• 1 tablespoon olive oil
• 1 cup milk (whole milk gives the creamiest results)
• ½ cup whipping cream
• 1 cup cheddar cheese, shredded (sharp cheddar adds extra flavor)
• Green onions, sliced for garnish
• Tabasco sauce to taste

Pro tip: I always keep extra Cajun seasoning on hand because every brand varies in spice level. Start with the tablespoon listed, then adjust at the end to match your family’s heat tolerance.

How to Make This Creamy Cajun Soup

I recommend browning your sausage first because it adds incredible depth to your hearty Cajun potato soup crockpot recipe. Don’t skip this step, it makes all the difference in the final flavor.

Step 1: Heat olive oil in a skillet over medium heat. Add sliced andouille sausage and cook for 5 to 7 minutes until the edges are browned with caramelized edges and fragrant. You’ll know it’s ready when the sausage releases its flavorful oils and develops a nice golden-brown color. Transfer the browned sausage to your slow cooker.

Step 2: Add diced potatoes, onion, bell pepper, carrots, celery, and minced garlic directly into the slow cooker with the sausage. No need to saute these vegetables, they’ll cook perfectly in the broth.

Step 3: Pour chicken broth over everything. Add Cajun seasoning, salt, and black pepper. Give it a good stir to make sure the spices coat all the ingredients evenly.

Step 4: Cover your crockpot with the lid and cook on low for 6 to 8 hours or on high for 3 to 4 hours. The soup is ready when the potatoes are fork-tender, meaning a fork should slide through easily with no resistance.

Step 5: About 30 minutes before serving, use a potato masher to mash potatoes 8 to 10 times with the masher right in the slow cooker, leaving visible chunks for texture. This natural thickening method is so much better than adding flour or cornstarch.

Step 6: Stir in milk and whipping cream. Continue cooking for another 20 to 30 minutes until everything is heated through and the dairy is fully incorporated. Watch for gentle bubbling around the edges.

Step 7: Add shredded cheddar cheese and stir until it melts completely into the soup, creating that rich, velvety texture. The soup will look smooth and glossy when the cheese is fully incorporated.

Step 8: Taste and adjust your seasonings. This is when I add Tabasco sauce, 1/4 teaspoon at a time and tasting between additions, until the heat level is just right. Remember, you can always add more but you can’t take it away.

Step 9: Ladle your hearty Cajun potato soup into bowls and garnish generously with sliced green onions. Serve hot with your favorite bread on the side.

Perfect Pairings for Your Cajun Soup

This hearty Cajun potato soup crockpot recipe pairs beautifully with breads that can soak up every drop of that creamy, spicy broth.

Cornbread: The slight sweetness of cornbread balances the spicy kick of Cajun seasoning perfectly. I love how the crumbly texture contrasts with the creamy soup.

Crusty French Bread: A warm baguette is ideal for dipping and adds a rustic touch to your meal. The crispy crust and soft interior make it the best side for Cajun potato soup.

Simple Green Salad: A crisp salad with vinaigrette cuts through the richness of the soup and adds freshness to your dinner plate.

Garlic Bread: Buttery garlic bread brings even more flavor to the table and is always a crowd favorite at my house.

Coleslaw: The cool, tangy crunch of coleslaw provides a nice contrast to the warm, spicy soup, especially during summer months.

Keeping Your Soup Fresh

Allow soup to cool for 30 minutes at room temperature before transferring to airtight containers. Store your leftover hearty Cajun potato soup crockpot in the refrigerator for up to 3 to 4 days. The flavors actually deepen overnight, making leftovers incredibly delicious.

For reheating, I recommend using the stovetop over low heat, stirring occasionally and adding a splash of chicken broth or milk if the soup has thickened too much. You can also reheat individual portions in the microwave for 2 to 3 minutes, stirring halfway through.

If you want to freeze this soup, it will keep for up to 2 months in freezer-safe containers. Thaw overnight in the refrigerator before reheating. Just know that the texture may change slightly as the potatoes can become a bit grainy after freezing. I find it still tastes great, just give it a good stir when reheating. Pro tip: Freeze in single-serving portions for quick weeknight dinners.
