Ingredients

• Potatoes
• Onion
• Garlic
• Cajun seasoning
• Chicken broth
• Heavy cream
• Butter
• Olive oil
• Smoked paprika
• Green onions
• Optional: bacon or sausage

Step-by-Step Instructions

1. Start by turning your Instant Pot to sauté mode. Add olive oil and butter, then let it heat until slightly shimmering. Add chopped onions and cook until they turn soft and slightly translucent. This builds the base flavor of your soup.
2. Add minced garlic and cook briefly until fragrant. Be careful not to burn it, as garlic cooks quickly and can turn bitter if overdone.
3. Sprinkle in Cajun seasoning along with smoked paprika, salt, and black pepper. Stir well so the spices coat the onions evenly, releasing their aroma and enhancing the flavor profile.
4. Add peeled and diced potatoes into the pot. Stir everything together so the potatoes absorb the seasoning mixture.
5. Pour in the chicken broth and give it a good stir, making sure nothing sticks to the bottom of the pot. This helps prevent the burn notice during pressure cooking.
6. Close the lid, set the valve to sealing, and cook on high pressure. Once done, allow a natural pressure release for a few minutes before carefully releasing the rest.
7. Open the lid and lightly mash some of the potatoes directly in the pot. This thickens the soup naturally while still leaving some chunks for texture.
8. Stir in the heavy cream and mix until the soup becomes smooth and creamy. Taste and adjust seasoning if needed.
9. Let the soup simmer on sauté mode for a few minutes to bring everything together. Garnish with chopped green onions and optional cooked bacon or sausage before serving.
