Ingredients You’ll Need
Here’s the best part: you probably have most of these ingredients sitting in your pantry and fridge right now. I’m picky about a few key ingredients here, so I’ll tell you why each one matters.
- Russet potatoes (4 medium, peeled and diced / about 800g) — These are starchy and perfect for thickening the soup naturally. Yukon Gold works too if you prefer a bit more buttery flavor.
- Olive oil (2 tablespoons / 30ml) — For sautéing the aromatics and spices. I use regular olive oil here, but avocado oil works great too.
- Yellow onion (1 medium, diced / about 150g) — Adds sweetness and depth. I avoid white onions because they can be too sharp.
- Green bell pepper (1 small, diced / about 100g) — Classic Cajun flavor base. You can swap with red or orange pepper for a sweeter touch.
- Celery stalks (2, diced / about 100g) — Gives that traditional Cajun “holy trinity” flavor. Don’t skip it!
- Garlic (4 cloves, minced / about 2 teaspoons) — Fresh only, please. This soup lives or dies by garlic.
- Cajun seasoning (2 tablespoons) — The soul of this soup. I use a store-bought blend, but homemade works too (paprika, cayenne, oregano, thyme, garlic powder, onion powder, black pepper).
- Chicken broth (4 cups / 960ml) — Low-sodium to control saltiness. Vegetable broth works if you want a vegetarian twist.
- Heavy cream (1 cup / 240ml) — For ultimate creaminess. Half-and-half is a lighter option but less rich.
- Smoked sausage (optional, 8 ounces / 225g, sliced) — I love adding Andouille for extra smoky flavor, but kielbasa or smoked chorizo works too.
- Green onions (3, sliced) — For garnish and a fresh pop of flavor.
- Shredded sharp cheddar cheese (optional, 1 cup / 100g) — I sprinkle some on top for a melty finish, but it’s great without.
Equipment Needed
You don’t need fancy gadgets for this. Here’s what I actually use:
- Instant Pot or Electric Pressure Cooker — This recipe is built for the Instant Pot, which cuts the cooking time drastically. If you don’t have one, a slow cooker could work but will take longer.
- Sharp knife — For chopping onions, peppers, celery, and potatoes. Dull knives make it harder and more dangerous, so invest in a good one.
- Cutting board — Plastic or wood, whichever you prefer.
- Wooden spoon or silicone spatula — For sautéing and stirring.
- Measuring spoons and cups — To keep the seasoning and liquids on point.
How to Make Instant Pot Cajun Potato Soup: Step-by-Step
Alright, let’s make this creamy Cajun potato soup! I’m walking you through exactly how I do it, including the little tricks I’ve picked up to get that perfect balance of spice and creaminess.
Step 1: Sauté Aromatics and Sausage (8 minutes)
Set your Instant Pot to “Sauté” mode and heat the olive oil. Add diced onions, bell pepper, and celery. Cook, stirring often, until they soften and smell sweet—about 4 minutes. Toss in the minced garlic and sauté another minute until fragrant, but don’t let it brown or burn.
If you’re using smoked sausage, add the sliced sausage now and sauté for 3-4 minutes until it starts to brown and release that smoky goodness.
Step 2: Add Potatoes, Cajun Seasoning, and Broth (2 minutes)
Stir in the diced potatoes and sprinkle the Cajun seasoning evenly over everything. Give it a good mix so the spices coat the potatoes and veggies. Pour in the chicken broth and scrape the bottom of the pot to loosen any browned bits. This adds deep flavor and prevents a burn warning on your Instant Pot.
Step 3: Pressure Cook (10 minutes)
Seal the Instant Pot lid and set it to “Manual” or “Pressure Cook” on high for 10 minutes. It will take a few minutes to come to pressure before the timer starts counting down.
Step 4: Quick Release and Add Cream (5 minutes)
When cooking is done, carefully perform a quick release to let out the steam. Remove the lid and stir the soup. It should be thick and the potatoes tender. Now stir in the heavy cream for that luscious, creamy texture. If you want a smoother soup, use an immersion blender to blend part or all of the soup to your desired consistency.
Step 5: Final Touches and Serve (5 minutes)
Adjust salt and pepper to taste. Ladle the soup into bowls and garnish with sliced green onions and shredded cheddar cheese if you like. A sprinkle of extra Cajun seasoning or a dash of hot sauce is great for those who want more heat.
Total time? About 30 minutes. That’s creamy Cajun potato soup ready fast, without sacrificing flavor.
Expert Tips & Tricks
- Don’t Skip the Quick Release — It stops the cooking immediately, so your potatoes don’t turn to mush. I burned this soup once by letting the pressure release naturally and it was a puree disaster.
- Use Low-Sodium Broth — Cajun seasoning can be salty, so controlling broth saltiness helps avoid an overly salty soup.
- Customize Your Spice Level — Start with 2 tablespoons of Cajun seasoning, then add more after cooking if you want it hotter. I like to keep hot sauce nearby for the table.
- Blend for Creaminess — For a velvety texture, blend half the soup with an immersion blender. No blender? Mash a few potatoes right in the pot with a wooden spoon.
- Make it Vegetarian — Swap chicken broth for vegetable broth and skip the sausage. Add smoked paprika for that smoky depth.
Variations & Substitutions
Once you’ve nailed this basic recipe, here are some ways to switch it up:
- Chicken and Cajun Potato Soup — Add shredded cooked chicken in the last 5 minutes for extra protein. This makes it even heartier, perfect after a long day.
- Veggie-Loaded Version — Toss in chopped kale or spinach right after pressure cooking, letting it wilt in the hot soup before serving.
- Cheesy Cajun Potato Soup — Stir in sharp cheddar or pepper jack cheese for a rich, melty twist.
- Spicy Cajun Potato Soup — Boost heat with cayenne pepper, diced jalapeños, or a splash of hot sauce.
- Dairy-Free — Use coconut milk or cashew cream instead of heavy cream. It changes the flavor but keeps the creaminess.
Serving & Storage
I like serving this soup straight from the pot, ladled into bowls with plenty of cheese and green onions piled on top. It pairs wonderfully with crusty bread or a simple green salad to balance the richness.
If you want a full meal, this soup goes well alongside quick dishes like my garlic brown sugar chicken or the creamy comfort of cajun chicken alfredo orzo. Both come together in about the same time and complement the soup’s flavors beautifully.
Storage: Store leftovers in an airtight container in the fridge for up to 4 days. The soup thickens as it chills—reheat gently in a saucepan over low heat with a splash of broth or cream to loosen it back up. Avoid microwave reheating unless you add liquid, as it tends to dry out.
Freezing: I don’t recommend freezing this soup because the cream can separate. Best to make fresh or freeze without the cream and add it when reheating.

Frequently Asked Questions
Q: Can I use milk instead of heavy cream?
A: You can, but the soup won’t be quite as rich or creamy. If you want to try it, use whole milk and add a tablespoon of flour or cornstarch mixed in to thicken the soup. I’ve done this when I ran out of cream—it’s okay, just not as decadent. Half-and-half is a better lighter option.
Q: My soup turned out watery—what went wrong?
A: Usually that means the potatoes didn’t release enough starch or you added too much broth. Make sure to use starchy potatoes like russets and don’t skip the pressure cooking time. If it’s watery after cooking, simmer the soup in “Sauté” mode for a few minutes to reduce liquid and thicken.
Q: Can I make this soup ahead for a party?
A: Yes! You can prepare the soup up to 2 days in advance. Store it in the fridge and reheat gently on the stove, adding a splash of broth or cream to loosen it up. It won’t lose much flavor and saves you time when guests arrive.
Q: Why did my soup get grainy after adding cream?
A: That happens if the cream is added too quickly to hot soup or if the soup was boiling. To avoid this, remove the pot from heat before stirring in cream, and add it slowly while stirring. If it’s grainy, whisk vigorously or use an immersion blender to smooth it out.
Q: Can I use jarred garlic instead of fresh?
A: I don’t recommend it. Jarred garlic often has a metallic aftertaste that stands out in creamy dishes. Fresh garlic adds brightness and depth. If you’re short on time, pre-peeled garlic cloves are a good shortcut.
Q: How do I reheat leftovers without drying them out?
A: Reheat on the stove over low heat with a splash of broth or cream, stirring frequently. This brings back the creamy texture. Microwave can dry it out unless you add liquid and heat in short bursts, stirring between.
Q: Can I double this recipe?
A: Absolutely! Just double all ingredients and use the largest Instant Pot size you have. Cooking time stays the same. Perfect for meal prepping or feeding a crowd.
