Step‑by‑Step Instructions for Instant Pot Cajun Potato Soup
Step 1: Sauté the Aromatics
Set your Instant Pot to sauté mode and pour in a tablespoon of olive oil. Once the oil is shimmering, add the chopped onion. Sauté for about 2-3 minutes, stirring occasionally, until the onion becomes soft and translucent, filling your kitchen with a delightful aroma.
Step 2: Add Garlic and Spices
Next, stir in the minced garlic and cook for an additional 30 seconds. This will release a beautiful fragrance! Then, sprinkle in the Cajun seasoning, paprika, and cayenne pepper, mixing well with the onions and garlic to create a luscious flavor base for your Instant Pot Cajun Potato Soup.
Step 3: Incorporate the Potatoes
Add the diced potatoes to the pot, making sure they are well coated with the spice mixture. This step ensures that every potato piece absorbs the robust flavors. Stir gently as you combine the ingredients, setting the stage for a creamy, flavorful broth.
Step 4: Add the Broth
Pour in the chicken broth, making sure to scrape up any bits stuck to the bottom of the pot to enhance flavor. Give everything a good stir to mix the potatoes evenly with the broth, creating a perfect harmony of ingredients for the soup’s base.
Step 5: Pressure Cook
Close the lid of your Instant Pot and ensure the valve is set to sealing. Select the “Pressure Cook” setting and adjust the time to 10 minutes on high pressure. As the Instant Pot heats up, the aroma of your Cajun Potato Soup will begin to fill your home, promising a delightful meal ahead.
Step 6: Release the Pressure
When the cooking time is complete, allow the Instant Pot to naturally release pressure for 5 minutes. Then, carefully switch to quick release for any remaining pressure. Once the lid is safe to open, you’ll be greeted with a steaming pot of creamy soup.
Step 7: Stir in the Cream and Cheese
Now, it’s time to make your soup rich and creamy! Stir in the heavy cream until fully combined, watching as it transforms the texture. Next, add the shredded cheddar cheese, stirring constantly until melted and incorporated into the soup, giving it that delightful indulgent richness.
Step 8: Season and Garnish
Taste your Instant Pot Cajun Potato Soup and season with salt and black pepper to your liking. Mix in the chopped green onions and crispy bacon bits for an added layer of flavor and texture. The vibrant colors and tempting aromas will have you eager to serve this comforting dish.
