Step‑by‑Step Instructions for Instant Pot Cajun Potato Soup
Step 1: Prepare the Instant Pot
Set your Instant Pot to Sauté mode and allow it to heat for about 1 minute. Once heated, pour in a splash of olive oil, swirling it around to coat the bottom of the pot. This will create a flavorful base for your Instant Pot Cajun Potato Soup.
Step 2: Sauté Onions
Add the chopped onions to the pot and sauté them for 2 to 3 minutes until they become soft and translucent. Stir occasionally to ensure even cooking and to prevent sticking. The aroma of the onions should fill your kitchen, signaling that you’re on the right track.
Step 3: Add Garlic
Stir in the minced garlic and cook for an additional 30 seconds. You want to wait just until you notice that fragrant garlic aroma wafting through the air, which indicates it’s ready to combine with the other ingredients. It’s time to amp up that flavor profile!
Step 4: Mix in Spices
Sprinkle the Cajun seasoning, paprika, and cayenne pepper over the sautéed onions and garlic. Stir well to coat the mixture with the spices evenly. This will unleash bold flavors, creating the heart and soul of your Instant Pot Cajun Potato Soup.
Step 5: Incorporate Potatoes
Add the diced potatoes to the pot, making sure they are well-coated with the spice mixture. Toss them gently for about 1 minute, allowing the flavors to infiltrate the potatoes. Their creamy texture will be the backbone of your soup, so give them some lovin’!
Step 6: Pour in Chicken Broth
Now, pour in the chicken broth and give it a good stir to combine all the ingredients. Scrape any bits from the bottom of the pot to prevent burning. The broth should fully cover the potatoes—a savory bath that will create a luscious soup.
Step 7: Seal the Instant Pot
Close the lid of the Instant Pot, ensuring the valve is set to Sealing. This is crucial for pressure cooking, allowing steam to build up. Feel that anticipation—your Instant Pot Cajun Potato Soup is about to take shape!
Step 8: Pressure Cook
Set the Instant Pot to Manual/Pressure Cook and adjust the timer to high pressure for 10 minutes. As the pot builds pressure, the countdown will begin. You’ll soon be rewarded with a creamy and flavorful soup that’s worth the wait!
Step 9: Release Pressure
After the cooking time elapses, allow the Instant Pot to naturally release pressure for 5 minutes. Then, carefully switch the valve to Venting to release any remaining steam. Be cautious of the hot steam escaping as you open the lid.
Step 10: Add Cream
Once you’ve opened the lid, stir the soup gently. Slowly mix in the heavy cream until it’s fully incorporated and the soup achieves that luxuriously creamy texture. The color will brighten, and the delicious aroma will be even more inviting!
Step 11: Incorporate Cheese
Add the shredded cheddar cheese gradually, stirring until it melts completely into the soup. This is what will make your Instant Pot Cajun Potato Soup truly indulgent. Taste and season with salt and pepper to your liking, giving it that perfect finishing touch.
Step 12: Garnish and Serve
Finally, toss in the chopped green onions and bacon bits for a nice crunch and pop of freshness. Ladle the soup into bowls and serve hot, allowing flavors to meld beautifully. This delightful Instant Pot Cajun Potato Soup is now ready to be enjoyed with crusty bread or your favorite salad!
