How to Make Slow Cooker Cajun Potato Soup
Now that we have our ingredients ready, let’s dive into the steps to create this delicious Slow Cooker Cajun Potato Soup. Each step is simple, and I promise you’ll feel like a culinary rockstar by the end!
Step 1: Prepare the Ingredients
Preparation is key to a smooth cooking process. Start by washing and peeling your russet potatoes. Cut them into bite-sized pieces, about an inch thick. This helps them cook evenly. Chop the bell pepper, onion, celery, and carrots into small, uniform pieces. Mince the garlic finely to release its flavor. Trust me, taking a little time to prep will make the cooking process a breeze!
Step 2: Sauté the Andouille Sausage
In your slow cooker, heat the olive oil over medium heat. Add the sliced andouille sausage and let it brown for about 5 minutes. This step is crucial! Browning the sausage enhances its flavor, giving your soup that rich, smoky taste. The aroma will fill your kitchen, making it hard to resist sneaking a taste!
Step 3: Add Vegetables and Seasonings
Once the sausage is nicely browned, it’s time to add the veggies. Toss in the potatoes, bell pepper, onion, celery, carrots, and minced garlic. Sprinkle in the Cajun seasoning, salt, and black pepper. Each of these ingredients contributes to the soup’s flavor profile, creating a delightful medley of tastes. Stir everything together to ensure the spices coat the vegetables evenly.
Step 4: Pour in the Chicken Broth
Now, it’s time to pour in the chicken broth. This liquid gold serves as the base of your soup, adding depth and richness. Make sure to stir everything well, so the broth mixes with the veggies and seasonings. If you prefer a vegetarian option, feel free to swap the chicken broth for vegetable broth!
Step 5: Cook the Soup
Cover your slow cooker and set it to low for 6-8 hours or high for 3-4 hours. The key here is patience! Check the doneness of the vegetables by poking them with a fork. They should be tender and easy to pierce. If you’re in a hurry, the high setting works just fine, but the low setting allows the flavors to meld beautifully.
Step 6: Stir in Dairy and Cheese
Once the cooking time is up, it’s time to make your soup creamy and dreamy! Stir in the milk and whipping cream, mixing well. Then, add the shredded cheddar cheese. This is where the magic happens! The cheese melts into the soup, creating a luscious, velvety texture that’s simply irresistible.
Step 7: Serve and Garnish
Now for the best part—serving! Ladle the soup into bowls and garnish with sliced green onions for a fresh crunch. If you like a little heat, add a dash of Tabasco sauce. This soup is perfect on its own, but you can also serve it with crusty bread or a simple salad for a complete meal.

Tips for Success
- Prep your ingredients the night before to save time in the morning.
- Adjust the Cajun seasoning to your spice preference—start with less and add more if needed.
- For a thicker soup, mash some of the potatoes with a fork before adding the dairy.
- Don’t skip the browning step for the sausage; it adds depth to the flavor.
- Store leftovers in an airtight container for up to 3 days or freeze for later!
