What Ingredients You Will Need
This Cajun potato soup recipe keeps things approachable but delivers that punchy, craveable flavor you want. Most of the ingredients are probably already in your kitchen, and you can easily swap things in or out based on what you’ve got.
- For the Soup Base:
- 4 cups (about 900g) russet potatoes, peeled and diced (Yukon Golds work too—just gives a creamier texture)
- 1 medium yellow onion, chopped
- 2 celery stalks, diced
- 1 large carrot, diced (adds a hint of sweetness)
- 4 cloves garlic, minced
- 1 red bell pepper, diced (adds color and crunch)
- 1 green bell pepper, diced
- 1 tablespoon (15ml) olive oil (for sautéing)
- 1/2 pound (225g) smoked sausage, sliced into half-moons (andouille is classic, but kielbasa or turkey sausage works too)
- For That Signature Cajun Flavor:
- 2 tablespoons (18g) Cajun seasoning (homemade or store-bought—see note below for a homemade mix)
- 1/2 teaspoon smoked paprika (for extra smokiness—optional but highly recommended!)
- 1/2 teaspoon dried thyme
- 1/4 teaspoon cayenne pepper (optional, for more heat)
- For the Creamy Finish:
- 4 cups (960ml) low-sodium chicken broth (vegetable broth works for a vegetarian version)
- 1 cup (240ml) whole milk, half-and-half, or heavy cream (choose based on how rich you want it)
- 2 tablespoons (28g) unsalted butter
- Salt & black pepper, to taste
- Optional Garnishes:
- Chopped fresh parsley or green onions
- Crumbled cooked bacon (for extra decadence)
- Shredded sharp cheddar cheese
- Hot sauce, for serving
Ingredient Tips: For the best Cajun potato soup, use firm, waxy potatoes if you want the chunks to hold shape. If you’re dairy-free, swap in coconut cream or your favorite non-dairy milk. And if you’re watching sodium, go with a homemade Cajun mix and low-sodium broth.
Homemade Cajun Seasoning: Mix 1 tablespoon paprika, 1 teaspoon each garlic powder, onion powder, oregano, thyme, and cayenne (or less, to taste), plus 1/2 teaspoon salt and 1/2 teaspoon black pepper. Easy peasy!
Equipment Needed
- Large Soup Pot or Dutch Oven: You want plenty of room for sautéing and simmering. I love my enameled cast iron Dutch oven for even heat, but any large pot works.
- Sharp Chef’s Knife & Cutting Board: Prepping veggies is way quicker (and safer) with a good, sharp knife.
- Wooden Spoon or Heat-Proof Spatula: For stirring and scraping up all those flavorful bits at the bottom of the pot.
- Measuring Cups & Spoons: For accuracy with spices and liquids.
- Blender or Immersion Blender (Optional): If you want a creamier texture, blend a portion of the soup. I usually use an immersion blender right in the pot for less mess.
- Ladle: For serving up big, hearty bowls!
If you don’t have an immersion blender, just carefully transfer some soup to a regular blender, blend, then pour it back in. (I’ve dropped a ladle or two in my day—no shame!) An old-school potato masher can also work for a rustic, chunky finish. And if you’re on a budget, most dollar-store pots and utensils will do the trick. Just avoid nonstick pots for this recipe—you want to get a little browning on the sausage and veggies for max flavor.
How to Make Cajun Potato Soup: Step-by-Step
-
Prep Your Ingredients:
Wash, peel, and dice the potatoes (roughly 1/2-inch cubes). Chop the onion, celery, carrot, bell peppers, and garlic. Slice the sausage into half-moons. This should take about 10-15 minutes. Pro tip: Chop everything before you start cooking—it makes the process so much smoother.
-
Sauté the Sausage:
Heat 1 tablespoon (15ml) olive oil in your soup pot over medium-high heat. Add the sliced sausage and cook for 3–4 minutes, stirring occasionally, until browned and fragrant. Remove sausage with a slotted spoon and set aside. This step builds a delicious flavor base—don’t skip it!
-
Cook the Veggies:
Add 2 tablespoons (28g) unsalted butter to the pot. Toss in the onion, celery, carrot, and both bell peppers. Sauté for 5–6 minutes, stirring often, until veggies are softened and onions are translucent. If they start to stick, add a splash of broth to loosen up the fond (browned bits).
-
Add Garlic & Spices:
Stir in the garlic, Cajun seasoning, smoked paprika, dried thyme, and cayenne pepper (if using). Cook for 1 minute, just until fragrant. You’ll smell those amazing spices bloom—this is when the kitchen starts to smell irresistible.
-
Add Potatoes & Broth:
Dump in the diced potatoes and return the browned sausage to the pot. Pour in 4 cups (960ml) chicken broth. Give everything a good stir, scraping up the bottom. Bring to a gentle boil, then reduce heat to low and cover. Simmer for 18–20 minutes, or until potatoes are fork-tender. (If your potatoes are cut larger, add a few extra minutes.)
-
Blend for Creaminess (Optional):
For a creamy Cajun potato soup, use an immersion blender to puree about 1/3 of the soup right in the pot. Or, carefully ladle a few cups into a blender, puree, and return to the pot. If you want a fully chunky soup, just skip this step! (I like a mix of creamy and chunky—best of both worlds.)
-
Add Milk or Cream:
Stir in 1 cup (240ml) milk, half-and-half, or heavy cream. Simmer uncovered for another 3–5 minutes, just to heat through. Taste and adjust salt and pepper as needed. If the soup is too thick, add a splash more broth or milk. Too thin? Let it simmer a bit longer, uncovered.
-
Serve and Garnish:
Ladle hot Cajun potato soup into bowls. Top with chopped parsley or green onions, shredded cheddar, bacon crumbles, or a dash of hot sauce—whatever you like. Serve with crusty bread for dunking (trust me, you’ll want it!).
Troubleshooting: If your soup tastes bland, add a pinch more salt or an extra sprinkle of Cajun seasoning. If it’s too spicy, swirl in a little extra cream or milk to mellow it out. Potatoes not soft? Simmer a few more minutes, checking every couple of minutes. And if you accidentally scorch the bottom (it happens!), carefully transfer the soup to a new pot—don’t scrape up the burnt bits.
Cooking Tips & Techniques for Cajun Potato Soup
- Layer Your Flavors: Don’t rush the browning step for sausage and veggies. Those golden bits build a savory base that makes the soup taste like it simmered all day.
- Choose the Right Potatoes: Russets make the soup creamy when blended, while Yukon Golds hold their shape better. Sometimes I use a mix for texture.
- Spice Carefully: Cajun blends vary—taste yours before adding. Some are super salty or fiery, so start with less and adjust at the end.
- Don’t Overcook the Dairy: Add milk or cream at the end. Boiling can cause curdling, so just heat it through gently.
- Keep It Moving: Stir often, especially after adding dairy, to prevent sticking or scorching. This is one soup you want to babysit a little!
- Multitask: While the soup simmers, prep your garnishes or slice crusty bread. Makes serving time a breeze.
I’ve learned (the hard way!) that adding all the Cajun seasoning up front can sometimes make things too spicy for kids. So, I start with half, then add more at the end if needed. Also, I once dumped in cold milk straight from the fridge—soup seized up and got grainy. Let your dairy warm up a bit on the counter before adding for smoother results.
Want perfect consistency every time? Blend only part of the soup. That way, you get creamy broth and hearty potato bites. And don’t be afraid to tweak—if you like thinner soup, add more broth; for thicker, simmer longer uncovered. Trust your taste buds!
Variations & Adaptations
- Vegetarian Cajun Potato Soup: Skip the sausage and use vegetable broth. Add a can of drained white beans or extra bell peppers for protein and heartiness.
- Dairy-Free: Substitute coconut cream or unsweetened almond milk for the dairy. Olive oil instead of butter works great, too. The flavor stays bold and creamy!
- Extra Protein: Stir in cooked shredded chicken or turkey right at the end. I’ve even tossed in leftover grilled shrimp for a Louisiana-inspired twist.
- Lower Carb: Try swapping half the potatoes for cauliflower florets. They blend up creamy and take on the Cajun spices beautifully.
- Spice Level: Adjust the cayenne or hot sauce to suit your family’s heat tolerance. My kids like it mild, so I keep the hot sauce on the side.
One of my favorite swaps? Using smoked turkey sausage for a lighter version. You still get that smoky flavor, but with less fat. In the summer, I toss in fresh corn kernels for a natural sweetness that balances the spice. If you’re gluten-free, double-check your sausage and broth labels—most are safe, but it’s always worth a look!
Serving & Storage Suggestions
Serving: Cajun potato soup is best piping hot, straight from the pot. I love ladling it into big bowls, topping with a sprinkle of chopped parsley or sliced green onions. Serve with crusty bread, cornbread, or even a scoop of cooked rice for extra comfort. A crisp salad with a tangy vinaigrette balances the richness nicely, and sweet iced tea or a cold beer is the perfect pairing.
Storage: Let leftovers cool to room temp, then transfer to airtight containers. Store in the fridge for up to 4 days. The flavors actually get better as they meld—soup always tastes even more savory on day two!
Freezing: This Cajun potato soup freezes well! Ladle cooled soup into freezer-safe bags or containers (leave a little room for expansion) and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
Reheating: Gently warm soup on the stove over low heat, stirring often. If it’s thickened up in the fridge, add a splash of broth or milk to loosen. Microwave in 1-minute bursts, stirring each time, until hot throughout.
