Slow Cooker Cajun Potato Soup Ingredients
For the Soup Base
- Olive Oil – Adds richness and helps brown the sausage; substitute with vegetable oil if needed.
- Andouille Sausage – Provides smoky, spicy flavor critical to the dish; opt for chorizo for a similar taste or turkey sausage for a lighter option.
- Russet Potatoes – Break down during cooking to thicken the soup and add creaminess; Yukon Gold potatoes can be used for a creamier texture.
- Bell Pepper – Adds a sweet flavor and vibrant color; any color bell pepper works well.
- Onion – Enhances flavor as a savory base; yellow or white onions are preferred.
- Celery – Contributes crunch and freshness; can be omitted if not available.
- Carrots – Adds slight sweetness and texture; substitute with parsnips for an earthy flavor.
- Garlic – Provides depth and aroma; fresh garlic is best, but pre-minced can be a time-saver.
- Cajun Seasoning – The key spice that gives the soup its heat; adjust to taste or substitute with Creole seasoning for less kick.
- Chicken Broth – Acts as the soup’s base; use low-sodium broth for a healthier option.
For Creaminess
- Milk – Provides creaminess; substitute with half-and-half for richer texture or low-fat milk for a lighter version.
- Whipping Cream – Adds richness; can use heavy cream for extra creaminess or omit for a lighter soup.
- Cheddar Cheese – Melts into the soup for a cheesy flavor; try a vegan cheese for dairy-free options.
For Garnish
- Green Onions – Used as a garnish for freshness and color; substitute with chives if needed.
- Tabasco Sauce – Optional for added heat and flavor; sprinkle on top to personalize your spice level.

Step‑by‑Step Instructions for Slow Cooker Cajun Potato Soup
Step 1: Brown the Sausage
Begin by heating 2 tablespoons of olive oil in a large skillet over medium heat. Add 12 ounces of sliced andouille sausage, cooking until it’s nicely browned, about 5-7 minutes. This step adds depth to the flavor of your Slow Cooker Cajun Potato Soup, so don’t skip it! Once browned, transfer the sausage to your slow cooker.
Step 2: Prepare the Vegetables
Next, chop 4 medium russet potatoes, 1 bell pepper, 1 onion, 2 celery stalks, and 2 carrots into bite-sized pieces. Mince 2 cloves of garlic to enhance the aroma. As you cut the vegetables, the colors will brighten your workspace and add vibrancy to your soup. Once prepped, add everything to the slow cooker with the sausage.
Step 3: Season the Mixture
Sprinkle 2 tablespoons of Cajun seasoning over the sausage and vegetables, along with salt and pepper to taste. Mix gently to ensure that the seasonings coat all the ingredients evenly. This infuses your Slow Cooker Cajun Potato Soup with that signature spicy kick!
Step 4: Add the Broth
Pour in 4 cups of chicken broth over the mixture in the slow cooker. Use a spoon to stir everything together, making sure the veggies and sausage are well combined and submerged in the broth. This will create a rich base that enhances the overall taste of the soup as it cooks.
Step 5: Slow Cook the Soup
Cover the slow cooker and set it to cook on high for 3 hours or low for 5 hours. During this time, the potatoes will become tender and creamy, thickening the soup naturally. The flavors will meld beautifully, creating a warm and inviting aroma in your kitchen.
Step 6: Cream it Up
After the cooking time is up, stir in 1 cup of milk for added creaminess. Allow the soup to cook for an additional hour on low. This step guarantees a luscious velvety texture in your Slow Cooker Cajun Potato Soup, perfect for cozy nights.
Step 7: Finish with Cheese
Add 1 cup of whipping cream and 1 cup of shredded cheddar cheese, stirring until the cheese melts into the soup, about 15 minutes. Watch as it transforms into a creamy, cheesy delight! If you prefer a lighter version, you can skip the cream or use lower-fat substitutes.
Step 8: Serve and Garnish
Once everything is well combined and heated through, ladle the soup into bowls. Finish with a sprinkle of chopped green onions and a dash of Tabasco sauce for added heat if desired. Each bowl of Slow Cooker Cajun Potato Soup is now ready to warm your heart and fill your belly!
