Creating this delicious Cajun Potato Soup is a rewarding and simple experience. Just follow these easy steps:

1. Sauté the Aromatics: In a large pot, heat the olive oil over medium heat. Add the chopped onion, bell pepper, and minced garlic. Sauté until the vegetables are soft, about 5 minutes.
2. Add Potatoes: Stir in the diced potatoes, then add the Cajun seasoning. Mix well to coat the potatoes with the spices.
3. Pour Broth: Add the chicken or vegetable broth to the pot. Bring to a boil, then reduce heat to a simmer. Cook until the potatoes are tender, about 20 minutes.
4. Blend for Creaminess: Once the potatoes are soft, use an immersion blender to blend the soup until smooth. If you don’t have an immersion blender, you can carefully transfer it to a regular blender in batches.
5. Stir in Cream: Return the blended soup to low heat, then stir in the heavy cream. Allow it to heat through without boiling.
6. Adjust Seasoning: Taste the soup and add salt, pepper, or more Cajun seasoning as desired.
7. Serve and Garnish: Ladle the warm soup into bowls, then top with chopped green onions and shredded cheddar cheese if using.

This straightforward process results in a truly amazing soup that is sure to impress!
