What Ingredients You Will Need

This Cajun potato soup recipe keeps things simple but packs in bold, comforting flavors. Most of the ingredients are probably hanging out in your kitchen already, and if not, there are plenty of easy swaps.

• For the soup base:
  • Yukon Gold or Russet potatoes, peeled and diced (about 2 pounds/900g) — Yukon Golds give a buttery texture, but Russets work too.
  • Yellow onion, diced (1 medium) — Adds sweetness and depth.
  • Celery stalks, diced (2) — Brings a subtle, fresh flavor.
  • Carrots, peeled and diced (2 medium) — For a hint of sweetness and color.
  • Garlic cloves, minced (3) — Fresh is best, but jarred works in a pinch.
  • Butter (2 tablespoons/28g) — For that rich, classic soup flavor.
  • Olive oil (1 tablespoon/15ml) — Helps with sautéing and adds a little heart-healthy fat.
  • Chicken or vegetable broth (4 cups/950ml) — Low sodium is great so you can control the saltiness.
  • Cajun seasoning (2 tablespoons/18g) — Use store-bought or homemade. I love Tony Chachere’s, but any blend works.
  • Salt and black pepper, to taste — Always taste and adjust!
• For creaminess:
  • Heavy cream (1 cup/240ml) — Makes it extra luscious. Swap with half-and-half or whole milk for a lighter version.
  • Cream cheese (2 ounces/56g, cubed) — Optional, but it melts in for an ultra-creamy finish. You can skip or use sour cream for a tangy note.
• For finishing & toppings:
  • Chopped scallions — For freshness and color.
  • Shredded cheddar cheese — Melts beautifully on top (optional but highly recommended).
  • Crumbled bacon — For extra crunch and smoky flavor (totally optional, but if you have leftover bacon, toss it on!).
  • Hot sauce — For those who want an extra kick.

Ingredient tips: If you’re out of carrots or celery, just add a bit more onion or swap in bell pepper (for a “trinity” flavor that’s classic Cajun). For gluten-free, just double-check your Cajun seasoning blend. And if you need this dairy-free, use olive oil only and swap cream with coconut milk or a plain, unsweetened plant-based alternative.

Honestly, the beauty of this soup is how forgiving it is. I’ve used leftover roasted potatoes, subbed in leeks for onions, and even thrown in chopped spinach at the end. The Cajun potato soup recipe adapts to what you have—and always turns out delicious.

Equipment Needed

• Large Soup Pot or Dutch Oven: You want something that holds at least 4-5 quarts (3.8–4.7 liters). I use a heavy-bottomed Dutch oven for even cooking and to prevent burning, but any big pot works as long as it has a lid.
• Sharp Chef’s Knife & Cutting Board: Prepping potatoes and veggies is way easier with a solid knife and a sturdy board. If yours is dull, give it a quick sharpen—it makes the whole process smoother.
• Wooden Spoon or Silicone Spatula: For stirring and scraping up any golden bits (that’s where the flavor hides!).
• Measuring Cups & Spoons: For accuracy, especially with the seasoning and broth.
• Immersion Blender or Potato Masher: For that creamy, velvety texture. If you don’t have an immersion blender, a regular blender (just work in batches and be careful with hot liquid!) or even a sturdy potato masher will do. I’ve even used a whisk in a pinch.
• Ladle: For serving, especially if you want to get every last bit out of the pot.

Pro tip: If you don’t have a Dutch oven, any large, thick-bottomed pot works fine. Just watch the heat and stir often to avoid sticking. And if you want to splurge, enamel Dutch ovens are worth every penny—mine’s survived a decade and still looks great!

How to Make Cajun Potato Soup – Step-by-Step

1. Prep your veggies and potatoes (10 minutes):
   
   Wash, peel, and dice 2 pounds (900g) of potatoes into bite-sized pieces. Dice 1 medium yellow onion, 2 celery stalks, and 2 carrots. Mince 3 garlic cloves. This is the “hardest” part—once you’re prepped, the rest is a breeze!
2. Sauté the aromatics (5 minutes):
   
   Heat 2 tablespoons (28g) butter and 1 tablespoon (15ml) olive oil over medium heat in your soup pot. Add the onion, celery, and carrots. Sauté for 3-4 minutes until they start to soften and smell sweet. Toss in the garlic and cook another 1 minute, just until fragrant—don’t let it brown, or it’ll turn bitter.
3. Add potatoes and Cajun seasoning (2 minutes):
   
   Stir in your diced potatoes and 2 tablespoons (18g) Cajun seasoning. Let the spices toast for a minute—this wakes up all the flavor. You’ll smell that smoky, peppery aroma right away!
4. Pour in broth and simmer (15 minutes):
   
   Add 4 cups (950ml) chicken or vegetable broth. Turn the heat to high, bring to a gentle boil, then reduce to a simmer. Cover and cook for 12-15 minutes, or until the potatoes are fork-tender. Tip: If your soup is bubbling wildly, turn the heat down to avoid mushy potatoes.
5. Blend for creaminess (2 minutes):
   
   Use an immersion blender to blend about half the soup directly in the pot—just a few pulses to keep some chunks. If you like it super creamy, blend more; for chunky, blend less. No immersion blender? Scoop a few cups into a regular blender, blend, then return to the pot (just don’t fill the blender too high—hot soup can splatter!).
6. Stir in cream & cheese (2 minutes):
   
   Lower the heat. Add 1 cup (240ml) heavy cream and 2 ounces (56g) cream cheese, stirring until the cheese melts in. Taste and add salt and black pepper as needed. If your soup is too thick, splash in more broth or milk; too thin, simmer uncovered for a few more minutes.
7. Finish and serve (2 minutes):
   
   Ladle soup into bowls. Top with scallions, shredded cheddar, crumbled bacon, and a dash of hot sauce if you like it spicy. Serve hot, with crusty bread for dunking!

Troubleshooting: If your soup is bland, add a bit more Cajun seasoning or a squeeze of lemon juice for brightness. If it’s too spicy, stir in more cream or a little plain yogurt. If you over-blend and it’s gluey, add extra broth and heat gently while stirring. Trust me, I’ve made every mistake—and this Cajun potato soup recipe always bounces back!

Cooking Tips & Techniques

• Layer flavors: Don’t rush the veggie sauté step. Let the onions get translucent and the carrots soften to build a sweet base. I used to just toss everything in, but trust me, this makes a difference.
• Spice level control: Cajun seasoning blends can vary wildly in heat and saltiness. Always taste your seasoning before adding, and adjust to your family’s preferences. I usually start with two tablespoons, then add more at the end if I want a bigger kick.
• Chunky vs. creamy: You control the final texture! I like a few big potato pieces left for a “rustic” feel, but if you want it totally smooth, keep blending. If you’re using a blender, pause and vent the lid to avoid soup explosions (been there, done that—soup on the ceiling isn’t fun!).
• Don’t overcook the potatoes: Boil just until fork-tender, not mushy. Overcooked potatoes will turn the soup gluey instead of creamy. If you’re multitasking, set a timer (I always forget and end up with potato mash otherwise!).
• Boost umami: Add a splash of Worcestershire sauce or a sprinkle of smoked paprika for even deeper flavor. It’s a trick I picked up after a few “meh” batches early on.
• Consistency fix: Soup too thick? Add more broth or milk until it’s just how you like it. Too thin? Simmer uncovered for a few minutes to let it thicken naturally.

Honestly, the biggest lesson I’ve learned is not to stress over perfection. This Cajun potato soup recipe is forgiving—if you make it with love (and taste along the way), it’ll turn out delicious every time.

Variations & Adaptations

One of my favorite things about this Cajun potato soup recipe is how easy it is to tweak. Here are a few ways you can mix it up depending on your mood, what’s in your fridge, or dietary needs:

• Protein Boost: Stir in cooked andouille sausage, rotisserie chicken, or shrimp at the end for a heartier meal. (I love tossing in leftover grilled chicken for a quick protein punch.)
• Vegetarian Version: Use veggie broth and add extra veggies like bell pepper, corn, or spinach. A can of drained white beans adds creaminess and protein, too!
• Dairy-Free or Vegan: Swap butter for more olive oil and use coconut milk or a thick, plain plant-based creamer instead of heavy cream and cheese. A dash of nutritional yeast gives a cheesy vibe—trust me, it works.
• Gluten-Free: This recipe is naturally gluten-free (just check your Cajun seasoning). If you need to thicken it more, mash a few extra potatoes instead of using flour.
• Lower Carb: Swap half the potatoes for cauliflower florets. They blend up creamy and cut the carb load without sacrificing comfort.
• Seasonal Twists: In summer, add fresh corn cut from the cob. In winter, toss in kale or chopped greens in the last few minutes for a nutrition boost.

Personally, my go-to twist is adding a handful of smoked sausage slices and a bit of corn—makes it taste like a cross between potato soup and a Louisiana chowder. Don’t be afraid to experiment and make it your own!

Serving & Storage Suggestions

I love serving this Cajun potato soup piping hot, topped with a sprinkle of scallions, a handful of shredded cheddar, and a little crumbled bacon. A hunk of crusty bread for dipping is basically required in my house, and a side salad with a citrusy vinaigrette balances out all the creamy richness nicely.

If you’re hosting, serve it in mugs or small bowls for a cozy starter. For a full meal, pair with a simple green salad or even a gooey grilled cheese—honestly, you can’t go wrong.

Leftovers keep really well! Store cooled soup in an airtight container in the fridge for up to 4 days. The flavors deepen as it sits (sometimes it’s even better the next day). For longer storage, freeze in individual portions for up to 2 months. Reheat gently on the stove or in the microwave, adding a splash of broth or milk if it thickens too much.

Tip: If you’ve added cheese or cream, stir well as you reheat to keep things smooth. And don’t forget the toppings—even reheated, this Cajun potato soup recipe loves a little fresh garnish!
