Creating a delicious pot of Creamy Cajun Potato Soup can be straightforward if you follow these easy steps:

1. Sauté the Aromatics: In a large pot, melt the butter over medium heat. Add chopped onion and minced garlic. Sauté until the onions are translucent and fragrant, about 5 minutes.

1. Add Potatoes: Stir in the diced potatoes and cook for another 2 minutes, allowing them to soak up the flavors.

1. Add Broth: Pour in the chicken or vegetable broth, bringing the mixture to a boil. Reduce heat and let it simmer for 15-20 minutes, or until potatoes are tender.

1. Blend the Soup: Once the potatoes are tender, use an immersion blender to blend the soup until smooth. You can also transfer it to a standard blender in batches if necessary.

1. Stir in Seasoning: Add Cajun seasoning, salt, and black pepper, stirring well to combine the flavors.

1. Mix in Cream: Reduce the heat to low, then add the heavy cream. Stir gently until fully blended and heated through, about 5 minutes. Adjust seasoning to taste.

1. Serve: Ladle the soup into bowls and garnish with sliced green onions and optionally, shredded cheddar cheese.

With these instructions, you can create a luscious and flavorful soup that truly embodies the essence of Cajun cuisine.
