Cajun Potato Soup Ingredients

For the Soup
• Yukon Gold Potatoes – The creamy base that gives the soup its luscious texture; you can also use Russet potatoes for a heartier feel.
• Yellow Onion – Adds a touch of sweetness and depth; shallots are a great substitute for a milder flavor.
• Green Bell Peppers – Contributes crispness and a pop of color; red or yellow bell peppers can be swapped in for a sweeter option.
• Garlic – Enhances flavor with its aromatic goodness; fresh garlic is ideal, but garlic powder can work in a pinch.
• Andouille Sausage – Introduces a smoky richness, but feel free to substitute turkey sausage or omit for a vegetarian option.
• Chicken Broth – Sets the stage for flavor; opt for vegetable broth to keep it vegetarian.
• Heavy Cream – Adds a velvety richness; coconut cream is a fantastic dairy-free alternative.
• Butter – Creates a luxurious mouthfeel when sautéing vegetables; olive oil can be used instead for a healthier choice.
• All-Purpose Flour – Essential for thickening the soup through a roux; gluten-free flour can be substituted for a gluten-free option.
• Cajun Seasoning – The star of the show that gives the soup it's signature flavor; tailor the amount to suit your spice preference.
• Smoked Paprika – Boosts the smoky undertones; regular paprika works if smoked isn't accessible.
• Cayenne Pepper – For those who love heat; scale back or omit if you’re sensitive to spiciness.
• Salt and Black Pepper – Vital for seasoning; consider using low-sodium options based on dietary needs.
• Green Onions – Fresh garnish that brightens up the dish; chopped parsley can be a lovely alternative.
• Shredded Cheddar Cheese – A delicious topping adding flavor; for a dairy-free twist, opt for vegan cheese.
• Sour Cream – Rounds out the soup's richness; Greek yogurt is a tangy substitute that works beautifully.
• Cooked Bacon Crumbles – Optional garnish for an extra flavor burst; simply leave it out for a vegetarian dish.

Step‑by‑Step Instructions for Cajun Potato Soup

Step 1: Prepare Ingredients
Begin by peeling and cubing about four medium Yukon Gold potatoes, aiming for 1-inch pieces for even cooking. Dice one yellow onion and two green bell peppers, and mince four cloves of garlic. This preparation will set you up for smooth sailing as you create your creamy Cajun Potato Soup.

Step 2: Cook Sausage
In a large heavy-bottomed pot, over medium heat, slice andouille sausage into bite-sized pieces. Add them to the pot and cook until browned, about 5-7 minutes, stirring occasionally. The sausage will release its smoky flavor, creating a savory base for your soup, so keep an eye on it until golden and fragrant.

Step 3: Sauté Vegetables
Once the sausage is cooked, add the diced onion and bell peppers to the pot. Sauté for 4-5 minutes until they become soft and translucent, stirring frequently. This step enhances the flavor of your Cajun Potato Soup, allowing the vegetables to meld beautifully with the sausage.

Step 4: Make Roux
Sprinkle ¼ cup of all-purpose flour into the pot with the sausage and veggies, stirring constantly for about 2-3 minutes. Cook until the roux is lightly golden, which will help thicken the soup, ensuring a creamy texture once combined with the broth. You should smell a nutty aroma as it cooks.

Step 5: Combine Liquids
Gradually whisk in 4 cups of chicken broth, allowing it to blend seamlessly as you bring the mixture to a gentle boil over medium-high heat. Once boiling, add the prepared potatoes along with 1 tablespoon of Cajun seasoning, 1 teaspoon smoked paprika, and a pinch of cayenne pepper if desired. Stir well before moving to the next step.

Step 6: Simmer
Reduce the heat to low and cover the pot. Let the soup simmer for 20-25 minutes, or until the potatoes are fork-tender. Keep an eye on the soup, lifting the lid occasionally to stir. This simmering process melds all the flavors together, creating a deliciously rich Cajun Potato Soup.

Step 7: Blend (Optional)
For a creamier texture, carefully ladle a portion of the soup into a blender and blend until smooth. Return the blended mixture to the pot and stir well to incorporate. If you prefer a chunkier soup, feel free to skip this step and enjoy the hearty morsels.

Step 8: Add Cream
Stir in ½ cup of heavy cream, letting it infuse into the soup. Taste and adjust seasoning with salt and black pepper if needed. The cream adds a lovely richness to your Cajun Potato Soup, making each spoonful velvety and satisfying.

Step 9: Final Simmer
Allow the soup to simmer on low heat for another 5-10 minutes without boiling, letting it meld together. This final simmer will enhance flavors, resulting in a satisfying bowl of comfort that is perfect for any occasion.

Step 10: Serve
Ladle the luscious Cajun Potato Soup into bowls and garnish with sliced green onions, shredded cheddar cheese, and a sprinkle of crumbled bacon if desired. Serve immediately with crusty bread or cornbread for a comforting meal that brings warmth to every bite.
