Method
 

Step 1:
  1. Place a large soup pot over medium heat. Add the butter and allow it to melt completely.
Step 2:
  1. Add the diced onion and cook for 3–4 minutes until soft and fragrant.
Step 3:
  1. Stir in the minced garlic and the white parts of the green onions. Cook for 1 minute, stirring continuously to prevent burning.
Step 4:
  1. Add the peeled, diced potatoes to the pot. Mix well until the potatoes are coated with the buttery onion mixture.
Step 5:
  1. Sprinkle the Cajun seasoning over the potatoes. Stir thoroughly so every piece absorbs the spices and becomes coated in flavor.
Step 6:
  1. Pour in the chicken or vegetable broth. Add salt and freshly cracked black pepper.
Step 7:
  1. Bring the mixture to a boil, then reduce the heat to low. Cover the pot and simmer for 15–20 minutes, or until the potatoes are soft enough to mash.
Step 8:
  1. Once the potatoes are tender, mash some of them directly in the pot using a potato masher. This naturally thickens the soup while still leaving chunks for texture.
Step 9:
  1. Pour in the heavy cream and stir until fully incorporated.
Step 10:
  1. Gradually add the shredded cheddar cheese, stirring continuously until it melts smoothly into the soup. The mixture should become creamy, thick, and velvety.
Step 11:
  1. Let the soup simmer uncovered for another 5 minutes to blend the flavors and thicken slightly more.
Step 12:
  1. Taste the soup and adjust seasoning. Add more Cajun seasoning if you want it spicier, or more salt and pepper based on preference.
Step 13:
  1. Turn off the heat and stir in the green parts of the sliced green onions for a fresh finishing touch.
Step 14:
  1. Ladle the soup into bowls and serve hot. For extra richness, top with more cheddar or a drizzle of cream.
