Spicy Cajun Soup

Featured in Soups & Stews.

A hug in a bowl with a spicy twist! Prepped quickly and mostly simmers itself. Smoky andouille flavors the creamy potato broth perfectly. Cheese melts into each spoonful. Not too fiery, just right. Crusty bread’s a must for dipping. Even tastier the next day.

I created my Spicy Southern Potato Soup on one cold night when I felt like giving my standard potato soup a Louisiana twist. When you mix up hot andouille sausage, soft potatoes, and thick creamy stock, you get what's now our go-to family meal. The amazing smells that fill up my kitchen whenever I cook this rich soup always bring everyone running to eat.

This Soup's Backstory

What started as me just playing around in the kitchen turned into the dish everyone asks me to make. There's something magical about how the smoky sausage mixes with the soft potatoes and that perfectly seasoned broth - it's like a warm hug in a bowl. I really love that you can make it as mild or spicy as you want, so it works for everyone from heat seekers to those who can't handle much spice.

Your Shopping List

  • Andouille Sausage: This gives you that real Southern flavor, but sometimes I grab kielbasa when cooking for folks who don't like things too spicy.
  • Cajun Seasoning: This is what makes everything pop with flavor. I'll tell you how you can mix up your own blend too.
  • Potatoes: I always pick Russets because they really soak up all the tasty flavors.
  • Chicken Broth: This makes the foundation of your soup, just be careful with salt if you're using regular stock.
  • Cheddar Cheese: I always grab extra so we can put more on top of each serving.

Cooking Steps

Sausage First
I always start by getting that andouille nice and brown with those crispy bits on the edges. You'll know you're on the right track just from how good it smells.
Creating the Base
In my big pot I cook down all the veggies with those warm Cajun spices. After the potatoes go in, I let everything bubble away until they're nice and soft.
Adding Richness
Now comes the fun part - pouring in cream and lots of melty cheese. When that sausage goes back into the mix, my kitchen smells just like I'm cooking in New Orleans.
Finishing Touches
I always try a spoonful to check if it needs more salt or spice, then it's ready to eat. There's never any left because everyone wants seconds.

Controlling the Spice

Here's my best advice if you're worried about making this soup too hot. Go easy on the Cajun seasoning at first - you can always sprinkle in more later. I've found that choosing a less spicy sausage makes a huge difference too. Sometimes when I'm feeling adventurous I'll throw in some extra cayenne, but it's really about making it taste good for whoever's eating it.

Storing Your Leftovers

I've made this soup so many times I know exactly how to keep it good. After it cools down, just put it in some containers and stick them in the fridge - it'll stay tasty for a few days. When you want to eat it again, just warm it up slowly on the stove. The funny thing is, it actually tastes even better the next day after all those flavors have had time to mix together.

Frequently Asked Questions

→ How can I tone down the spice?
Use a smaller amount of Cajun spices and skip the cayenne. Swap out andouille for a milder smoked sausage option.
→ Which kind of potatoes should I use?
Russet potatoes work best. They soften to thicken the soup while still giving you hearty bites.
→ Is it okay to cook this ahead?
Totally! Keep it in the fridge for up to 3 days. Reheat slowly while stirring so everything blends smoothly.
→ What goes well with this soup?
Grab some crusty bread or cornbread to soak up that broth. A crisp salad adds a nice contrast too.
→ Can this be frozen?
Cream-based soups can split after freezing. If you’re freezing it, leave out the cream and cheese and add them after reheating.

Cuisine: Cajun

Yield: 6 Servings (8 cups soup)

Dietary: Gluten-Free

Ingredients

01 1 large onion, chopped into small pieces (roughly 1 cup).
02 1 tablespoon of cooking oil.
03 Half a red bell pepper, diced without seeds.
04 1 rib of celery, chopped fine (makes about half a cup).
05 2 teaspoons of freshly chopped garlic.
06 13.5 ounces of andouille sausage, sliced into thin rounds.
07 Half a teaspoon of kosher salt.
08 1 teaspoon of Cajun spices.
09 4 large russet potatoes, peeled and chopped into cubes.
10 4 cups chicken stock.
11 Half a teaspoon of black pepper.
12 1 cup of shredded mild cheddar.
13 Half a teaspoon of paprika spice.
14 A pinch (quarter teaspoon) of cayenne for heat.
15 Half a cup of heavy cream.
16 Fresh parsley, minced for topping.

Instructions

Step 01

Set a big pot on medium heat and swirl in the oil. Toss in the sausage and fry until browned on both sides, 3-4 minutes. Pull it out and set it aside.

Step 02

Without cleaning the pot, throw in the onion, bell pepper, and celery. Let it soften for 5-8 minutes. Stir in the garlic and cook just 1 minute longer.

Step 03

Mix in the dry spices, chicken stock, and potatoes. Bring the heat down low, then let it gently bubble until the potatoes are fork-tender—about 20-25 minutes.

Step 04

Stir the sausage back into the pot. Add in the cream and cheese, then cook for another 5 minutes until hot and the cheese has melted well.

Step 05

Dish it up warm with parsley sprinkled on top.

Notes

  1. The mix of onion, celery, and pepper (Trinity) adds that real Cajun vibe.
  2. Turn up or bring down the spice with more or less Cajun seasoning or cayenne.
  3. Russet potatoes naturally make the soup thick and creamy.
