Follow these simple steps to create delicious Cajun Potato Soup:

1. Prepare the Ingredients: Peel and dice the potatoes, dice the onion, and mince the garlic.
2. Heat the Oil: In a large pot or Dutch oven, heat the olive oil over medium heat.
3. Sauté the Vegetables: Add the diced onion and minced garlic to the pot. Sauté until the onion is translucent, about 4-5 minutes.
4. Add Potatoes: Stir in the diced potatoes and Cajun seasoning. Cook for an additional 2 minutes to toast the spices.
5. Pour in Broth: Add the vegetable broth to the pot, ensuring that the potatoes are submerged. Bring to a boil.
6. Simmer: Reduce the heat to low and cover the pot. Let it simmer for 25-30 minutes, or until the potatoes are tender.
7. Blend the Soup: Use an immersion blender to puree the soup until smooth. If using a regular blender, carefully transfer the soup in batches.
8. Add Cream and Seasoning: Stir in the heavy cream (or coconut milk) and cayenne pepper. Season with salt and pepper to taste. Heat through for an additional 5 minutes.
9. Adjust Consistency: If the soup is too thick, add more broth or water until you reach your desired consistency.
10. Serve: Ladle the soup into bowls. Garnish with chopped green onions and fresh parsley before serving.

These steps ensure you create a warming bowl of Cajun Potato Soup that will be loved by everyone.
