Creating Cajun Potato Soup is simple if you follow these steps:

1. Prepare Ingredients: Start by peeling and dicing your potatoes, chopping the onion, celery, and carrots, and mincing the garlic.
2. Sauté Vegetables: Heat olive oil in a large pot over medium heat. Add the onion, celery, and carrots. Sauté for about 5-7 minutes until the vegetables are tender.
3. Add Garlic: Stir in the minced garlic and cook for an additional 1-2 minutes until fragrant.
4. Add Potatoes and Broth: Pour in the diced potatoes and broth. Bring to a boil, then reduce the heat and let it simmer for about 20-25 minutes, or until the potatoes are fork-tender.
5. Season the Soup: Stir in the Cajun seasoning, salt, and black pepper. Adjust seasoning according to your taste.
6. Blend for Creaminess: Use an immersion blender to blend the soup to your desired smoothness, or transfer part of the soup to a blender, then return it to the pot.
7. Stir in the Cream: Add the heavy cream and stir well. Heat through for about 5 minutes.
8. Add Protein (if desired): If using sausage or bacon, fold it into the soup during the last few minutes of cooking.
9. Taste and Adjust: Taste the soup one last time and adjust any seasoning if necessary.
10. Serve Hot: Remove from heat, and prepare to serve.

By following these straightforward steps, you can easily create a bowl of Cajun Potato Soup that is rich, creamy, and full of flavor.
