Pro Tips and Variations
To get the best results with your Instant Pot Cajun Potato Soup always ensure your potato chunks are roughly the same size so they cook evenly. If you find the soup is too thin a cornstarch slurry can work wonders. Simply mix a tablespoon of cornstarch with cold water and stir it into the bubbling soup at the end.
For a spicy version add a teaspoon of hot sauce or extra cayenne pepper. If you are looking for a gluten free option just ensure your Cajun seasoning and sausage brands are certified.

Serving Suggestions
A bowl of Instant Pot Cajun Potato Soup is a star on its own but pairings make it an event. Here are a few favorites from my own table:
- Buttery Cornbread: The sweetness of the corn perfectly balances the spice of the Cajun seasoning.
- Garden Salad: A crisp fresh salad with a light vinaigrette cleanses the palate between bites of rich soup.
- Garlic Bread: Great for dipping and soaking up every last drop of that creamy broth.
- Steamed Vegetables: Broccoli or green beans add a nice crunch and a healthy boost to the meal.
Storage and Reheating for Instant Pot Cajun Potato Soup
This soup keeps beautifully in the fridge. Simply place leftovers in an airtight container for up to 4 days. When you are ready to enjoy it again reheat it on the stove over medium heat stirring occasionally to maintain the creamy texture. If the soup has thickened too much in the fridge add a splash of milk or broth while heating.
Freezing is possible but keep in mind that dairy based soups can sometimes change texture when thawed. If you plan to freeze it I recommend doing so before adding the heavy cream then adding the cream during the reheating process.
