Ingredients for Cajun Potato Soup

Here’s everything you’ll need for that perfect bowl of comfort:

4 cups diced potatoes (peeled Yukon Gold work best)
1 large onion, chopped (about 1 cup)
2 celery stalks, chopped
1 green bell pepper, diced
3 cloves garlic, minced
4 cups chicken broth (low sodium preferred)
1 cup heavy cream
2 tbsp Cajun seasoning (packed)
1 tsp smoked paprika
Salt and black pepper to taste
2 tbsp unsalted butter
2 tbsp all-purpose flour (leveled)
1 lb Andouille sausage, sliced into coins
Chopped green onions (optional garnish)

Ingredient Notes & Substitutions

No Andouille? Smoked kielbasa works in a pinch! For vegetarians, swap chicken broth for vegetable broth and omit the sausage (add extra smoked paprika instead). Too spicy? Start with 1 tbsp Cajun seasoning and adjust. Store leftover heavy cream tightly sealed for up to 10 days. Pro tip: Prep all veggies before starting – it makes the cooking process smoother!

How to Make Cajun Potato Soup

Okay, let’s get cooking! Here’s exactly how I make my favorite Cajun potato soup – follow these steps and you’ll have potful of comfort in no time:

Start with the holy trinity: Melt butter in a large Dutch oven over medium heat. Add onion, celery, and bell pepper. Cook for about 5 minutes, stirring occasionally, until the veggies soften but don’t brown.
Build flavor: Stir in garlic and Cajun seasoning – your kitchen should smell amazing now! Cook for 1 minute until fragrant. This wakes up all those spices.
Make the roux: Sprinkle flour over the veggies and cook for 2 minutes, stirring constantly. It’ll look pasty – that’s perfect! This thickens the soup beautifully.
Add liquids gradually: Slowly pour in chicken broth while stirring continuously to prevent lumps. Scrape up any browned bits from the bottom – that’s flavor!
Cook potatoes: Add potatoes, smoked paprika, salt, and pepper. Bring to a gentle boil, then reduce heat to medium-low. Simmer uncovered for 15 minutes until potatoes are fork-tender.
Finish with cream: Stir in heavy cream and sausage slices. Let it simmer for 5 more minutes to heat through. Taste and adjust seasoning – I always add extra black pepper!

Tips for the Best Cajun Potato Soup

Here are my secret weapons for soup success: Brown sausage separately first for extra flavor (drain fat before adding). Always temper cream by stirring in a spoonful of hot broth first to prevent curdling. Want more depth? Add a splash of Worcestershire sauce! Remember – you can add more spice, but you can’t take it out, so season gradually. And don’t skip letting the soup rest for 10 minutes before serving – the flavors meld beautifully!

Serving Suggestions for Cajun Potato Soup

This hearty Cajun potato soup is a meal all on its own, but I love serving it with warm, crusty French bread for dunking – trust me, you’ll want to soak up every last drop! For a lighter meal, pair it with a crisp green salad dressed in tangy vinaigrette. Garnish bowls with extra sliced green onions, a dollop of sour cream, or a sprinkle of reserved crispy sausage slices. My husband always reaches for the hot sauce bottle to add an extra kick – keep it on the table for spice lovers!

Storage & Reheating Instructions

This Cajun potato soup keeps beautifully! Store leftovers in an airtight container in the fridge for up to 3 days – the flavors actually deepen overnight. For longer storage, freeze portions for 2-3 months (thaw overnight in fridge before reheating). Always reheat gently on the stovetop over medium-low heat, stirring occasionally. Microwaving can make the cream separate, leaving you with unevenly heated soup. A splash of broth or cream refreshes the texture if needed!

FAQs About Cajun Potato Soup

Can I make this soup ahead of time?
Absolutely! In fact, I think it tastes even better the next day. Just prepare as directed, let it cool completely, then store in the fridge for up to 3 days. When ready to serve, reheat gently on the stove – you might need to add a splash of broth or cream to loosen it up.

How can I reduce the spiciness?
First, cut the Cajun seasoning in half (you can always add more later). Using sweet Italian sausage instead of Andouille helps too. Stirring in a spoonful of sour cream or plain yogurt at serving time tames the heat beautifully while adding creaminess.

Can I freeze Cajun potato soup?
You bet! It freezes great for 2-3 months. I like to portion it into freezer bags (lay flat to save space) or individual containers. The potatoes might soften slightly when thawed, but the flavor stays amazing. Pro tip: Leave out the cream if freezing – add it fresh when reheating.

What potatoes work best?
I swear by Yukon Golds – they hold their shape but get perfectly tender. Russets work too but may break down more. Red potatoes stay firm if you prefer chunkier soup. Just avoid waxy varieties like fingerlings for this recipe.

Can I make it vegetarian?
Of course! Swap chicken broth for veggie broth, skip the sausage (or use plant-based), and add extra smoked paprika for that signature depth. I sometimes throw in a can of white beans for protein – they’re fabulous with the Cajun flavors!
