how to make Instant Pot Cajun Potato Soup

To make Instant Pot Cajun Potato Soup, you’ll start by prepping your ingredients. First, gather 4 cups of diced potatoes, a tablespoon of olive oil, one medium onion (chopped), two cloves of garlic (minced), and a blend of spices including one teaspoon of Cajun seasoning, half a teaspoon of paprika, and a quarter teaspoon of cayenne pepper. You’ll also need 4 cups of chicken broth, 1 cup of heavy cream, 1/2 cup of shredded cheddar cheese, a quarter cup of sliced green onions, and some crispy bacon bits for added flavor.

Begin by turning on your Instant Pot and setting it to Sauté mode. Add the olive oil and let it heat up. Once hot, toss in the chopped onion and cook for 2-3 minutes until it softens. Next, add the minced garlic and cook for an additional 30 seconds, stirring to avoid burning.

Now, sprinkle in the Cajun seasoning, paprika, and cayenne pepper, stirring well to mix the spices with the onions and garlic. Add in the diced potatoes, stirring to coat them in the spice mixture. Pour the chicken broth into the pot, stirring everything together.

Close the lid of the Instant Pot, ensuring the valve is set to Sealing. Set it to Manual or Pressure Cook on high for 10 minutes. While the soup cooks, prepare the heavy cream, shredded cheese, green onions, and bacon bits.

When the cooking time is up, let the Instant Pot release pressure naturally for about 5 minutes. After that, carefully switch the valve to Venting to release any remaining pressure. Once it’s safe to open, stir the soup. Add the heavy cream and stir until the soup is smooth. Mix in the shredded cheddar cheese until melted and creamy. Season with salt and black pepper to taste. Finally, stir in the sliced green onions and bacon bits, saving some for garnishing if you’d like.

This hearty soup is ready to serve hot, topped with the remaining green onions and bacon bits for a delightful crunch.

how to serve Instant Pot Cajun Potato Soup

Serve your Instant Pot Cajun Potato Soup hot, ideally in bowls garnished with extra green onions and bacon bits. Pair it with crusty bread or a fresh salad to create a complete meal. It’s great for family gatherings or even as a comforting dinner on a chilly night.

how to store Instant Pot Cajun Potato Soup

To store any leftover soup, let it cool and place it in an airtight container. You can keep it in the refrigerator for up to 3-4 days. For longer storage, consider freezing it in suitable containers. When you’re ready to enjoy it again, simply thaw it overnight in the fridge and reheat it on the stove or in the microwave.

tips to make Instant Pot Cajun Potato Soup

  1. For a spicier kick, increase the amount of cayenne pepper or add hot sauce directly to the soup.
  2. Use fresh potatoes for the best flavor and texture; russet or Yukon gold work well.
  3. For a vegetarian version, swap the chicken broth for vegetable broth and omit the bacon.
  4. Letting the soup sit for a little while after cooking can enhance the flavors.
  5. Adjust the pasta size or thickness based on your preference for a thicker or thinner soup.
  6. Add other vegetables like corn or bell peppers to the mix for added nutrition and flavor.
  7. If you like it extra creamy, consider adding more heavy cream or a splash of milk.
