Cheddar Cheese
Mild cheddar adds creaminess and flavor. Another melting cheese can be used if preferred.
Chicken Broth
Chicken broth creates the soup base, but another suitable broth can be used depending on availability.
How to Make Cajun Potato Soup

Step 2: Cook the Vegetables
Using the same pot, add onion, celery, and red bell pepper.
Cook for 5–8 minutes until the vegetables soften.

Step 3: Build the Soup Base
