For the Soup Base
- 4 cups potatoes, diced – Perfect for that creamy texture; Yukon Gold is highly recommended!
- 1 tablespoon olive oil – Adds richness when sautéing; can swap for vegetable oil if needed.

- 2 cloves garlic, minced – Elevates flavor; fresh garlic is ideal, though powder can work in a pinch.

- 1/2 teaspoon salt – Essential for flavor; adjust to your taste.
- 1/4 teaspoon black pepper – Provides mild heat; white pepper is a fun substitute!
For Creaminess and Flavor
- 1 cup heavy cream – Gives that desired creaminess; you can substitute half-and-half for a lighter option.
- 1/2 cup shredded cheddar cheese – Melts beautifully into the soup; Monterey Jack or Gouda would also work well.
For Garnish

Step‑by‑Step Instructions for Instant Pot Cajun Potato Soup
Step 1: Sauté Aromatics
Begin by turning your Instant Pot to the Sauté mode, allowing it to heat for about 1 minute. Add 1 tablespoon of olive oil, swirling to coat the bottom. Once the oil shimmers, toss in the chopped onion. Sauté for 2-3 minutes until the onion becomes translucent and fragrant, infusing the pot with a delightful aroma.
Step 2: Add Garlic and Spices
Next, stir in the minced garlic and cook for an additional 30 seconds, letting its rich essence fill the air. Sprinkle in 1 teaspoon of Cajun seasoning, 1/2 teaspoon of paprika, and 1/4 teaspoon of cayenne pepper, stirring well to combine with the onions and garlic. This vibrant mixture will create a flavorful foundation for your Instant Pot Cajun Potato Soup.
Step 3: Incorporate Potatoes
Now, add the diced potatoes to the pot, giving them a good stir to coat with the seasoned mixture. This step melds the potatoes with the bold flavors, enhancing their comfort-food quality. Ensure the potatoes are evenly distributed, creating a hearty base for the upcoming broth.
Step 4: Add Chicken Broth
Pour in 4 cups of chicken broth, stirring gently to combine all the ingredients. This savory liquid will create a rich, flavorful soup base. As the broth mingles with the spices and potatoes, you’ll start to notice the beautiful colors and textures blending together in your Instant Pot.
Step 5: Pressure Cook
Secure the Instant Pot lid in place, making sure the valve is set to “Sealing.” Select the Pressure Cook function and set it for high pressure for 10 minutes. As the pot heats up, it will begin to build pressure, ensuring that every bite of your Cajun potato soup is bursting with flavor.
Step 6: Release Pressure
Once the cooking time is complete, allow the Instant Pot to naturally release pressure for 5 minutes. Afterward, carefully turn the valve to “Venting” to release any remaining steam. Be cautious of the hot steam escaping, and once the lid unlocks, gently remove it to reveal your perfectly cooked Instant Pot Cajun Potato Soup.
Step 7: Stir in Cream
With the lid off, stir in 1 cup of heavy cream, which will transform your soup into a creamy delight. Mix thoroughly until the cream is fully incorporated, adding a luscious texture to your dish. At this point, take a moment to appreciate the warm, inviting aroma wafting through your kitchen.
Step 8: Add Cheese and Season
Next, add 1/2 cup of shredded cheddar cheese to the soup, stirring until it melts completely and blends into a rich, comforting mixture. Taste and adjust the seasoning with salt and freshly ground black pepper as needed, creating a perfect balance of flavors in your Instant Pot Cajun Potato Soup.
Step 9: Finish with Garnish
Finally, fold in 1/4 cup of sliced green onions and 1/2 cup of bacon bits for an added layer of flavor and texture. This final touch brings freshness and that delightful smoky crunch, completing your hearty dish. Serve it hot, enjoying the warmth and satisfaction that each bowl of your Instant Pot Cajun Potato Soup can offer.

Make Ahead Options
These Instant Pot Cajun Potato Soup preparations are perfect for busy weeknights! You can dice the potatoes, chop the onions, and mince the garlic up to 24 hours in advance, storing them in the refrigerator to keep them fresh. Additionally, you can measure out your spices and combine them in a small bowl to save time later. When you’re ready to cook, simply sauté the aromatics in your Instant Pot, add the prepped ingredients, and continue with the recipe as directed. For best results, remember to refrigerate leftovers in an airtight container for 3-4 days. This way, you’ll enjoy the same rich and comforting flavor with minimal effort!
