Possible Substitutes for Each Ingredient

- Onion can be switched with shallots for a milder taste.
- Any color bell pepper works if red is unavailable.
- Heavy cream can be swapped for half-and-half for a lighter option.
Cooking Instructions
Step-by-Step Preparation
Start by heating the vegetable oil in a large pot over medium heat. Add the sausage slices and cook until browned, about 3-4 minutes. Remove the sausage and set it aside.
In the same pot, toss in the diced onion, celery, and bell pepper. Sauté these vegetables until they soften, which should take about 5-8 minutes. Add the minced garlic and cook for an additional minute.
Next, sprinkle in the Cajun seasoning, kosher salt, black pepper, paprika, cayenne pepper, chicken broth, and cubed potatoes. Lower the heat and let the mixture simmer for 20-25 minutes, or until the potatoes are tender.
Return the cooked sausage to the pot, stirring in the heavy cream and shredded cheese. Simmer for another 5 minutes until everything is heated through and the cheese has melted.
Garnish with chopped parsley and serve warm for a satisfying meal.

Tips for Perfecting Your Soup
- Ensure the sausage is nicely browned to enhance the flavor.
- Don’t rush the simmering process; it allows the flavors to meld beautifully.
- Taste as you go to adjust the seasoning to your liking.
Adjusting Spice Levels
How to Make It Milder
If you prefer a milder soup, reduce the amounts of Cajun seasoning and cayenne pepper. You can also use less sausage for less spice while maintaining the richness of the dish.
Customizing Heat to Your Preference
For those who enjoy an extra kick, feel free to add more cayenne pepper or a dash of hot sauce before serving. Adjusting the spice levels ensures everyone gets their perfect bowl!
Storing & Reheating Cajun Potato Soup
Best Practices for Storage
You can keep your delicious Cajun potato soup in an airtight container in the refrigerator for up to 3-4 days. For longer storage, consider freezing it for future meals.

Reheat the soup either in the microwave or on the stovetop. If using the stovetop, heat it gently to avoid scorching while preserving its creamy texture.
Freezing Cajun Potato Soup
Steps for Freezing
To freeze the soup, allow it to cool completely before transferring it into freezer-safe containers. It’s best to leave some space at the top, as the soup will expand when frozen.
