How to Make Slow Cooker Cajun Potato Soup
Step-by-Step Instructions
Step 1: Prepare the Sausage Heat olive oil in a large skillet over medium-high heat. Add the sliced andouille sausage and cook for 3-4 minutes until lightly browned on both sides. This step adds extra flavor and texture to the soup. Transfer the browned sausage to your slow cooker.
Step 2: Add Vegetables and Seasonings Add the diced potatoes, bell pepper, onion, celery, carrots, and minced garlic to the slow cooker with the sausage. Sprinkle the Cajun seasoning, salt, and black pepper over the vegetables, ensuring everything is evenly distributed.
Step 3: Pour in the Broth Pour the chicken broth over the ingredients in the slow cooker. The liquid should just cover the vegetables. If needed, add a little more broth or water to ensure proper coverage.
Step 4: Slow Cook Cover and cook on LOW for 6-7 hours or HIGH for 3-4 hours, until the potatoes are tender and easily pierced with a fork. The vegetables should be completely cooked through and the flavors well combined.
Step 5: Add Dairy and Cheese In the last 30 minutes of cooking, stir in the milk and whipping cream. Add the shredded cheddar cheese and stir until melted and fully incorporated. Taste and adjust seasoning if needed.
Step 6: Serve Ladle the soup into bowls and garnish with sliced green onions. Serve with Tabasco sauce on the side for those who want extra heat.
Helpful Tips
Browning the Sausage: While you can skip browning the andouille sausage, taking this extra step significantly enhances the flavor profile of your Slow Cooker Cajun Potato Soup. The caramelization adds depth and richness that makes a noticeable difference in the final dish.
Potato Selection: Russet potatoes work best for this recipe because they break down slightly during cooking, naturally thickening the soup while maintaining some texture. Avoid waxy potatoes like red or Yukon, which won’t provide the same creamy consistency.
Cajun Seasoning: For the most authentic flavor, use a high-quality Cajun seasoning blend. You can also make your own by combining paprika, garlic powder, onion powder, oregano, thyme, cayenne pepper, and black pepper.
Dairy Addition Timing: Always add the milk, cream, and cheese in the final 30 minutes of cooking to prevent curdling. If your soup appears to curdle, blend a portion of it to restore smoothness.
Consistency Control: If your soup is too thick, add more broth or milk. If it’s too thin, mash some of the potatoes against the side of the slow cooker or remove a cup of soup, blend it, and stir it back in.
