Step-by-Step Cooking Instructions

Stir in diced potatoes, Cajun seasoning, salt, and black pepper. Mix to coat the potatoes evenly with the spices. - Add broth and pressure cook
Pour in chicken broth, ensuring potatoes are covered. Close the lid, set the valve to sealing, and cook on High Pressure for 8 minutes. - Release pressure and blend
Once the cooking time is complete, perform a quick release. Use an immersion blender to partially blend the soup, leaving some potato chunks for texture. - Add cream and cheese
Stir in heavy cream and shredded cheddar cheese until fully melted and creamy. Adjust seasoning as needed. - Serve hot
Ladle into bowls and garnish with sliced green onions or extra Cajun seasoning for added flavor.
