Description

Slow Cooker Cajun Potato Soup: Creamy, comforting, and easy to make, this hearty soup features tender potatoes, onion, celery, peppers, and a bold Cajun seasoning. The slow cooker does the work, finishing with cream and a light cornstarch slurry for silky thickness. Ideal for chilly days or busy evenings, this cozy bowl yields 6 servings with a warm Cajun kick. Dairy-rich but adaptable, it can be lightened with skim milk and heat adjusted to taste. Sturdy leftovers pair with crusty bread.

Ingredients

Scale

2 lbs potatoes, peeled and diced
1 small onion, diced
2 cloves garlic, minced
2 celery stalks, diced
1 red bell pepper, diced
4 cups chicken broth (halal)
1 cup heavy cream
1 cup milk
1 tsp Cajun seasoning
½ tsp smoked paprika
½ tsp dried thyme
½ tsp salt, or to taste
¼ tsp black pepper
2 tbsp cornstarch mixed with 2 tbsp water
Optional: chopped green onions or parsley for garnish

Instructions

Place potatoes, onion, garlic, celery, bell pepper, and chicken broth in the slow cooker.
Stir in Cajun seasoning, paprika, thyme, salt, and pepper.
Cover and cook on low for 6–7 hours or on high for 3–4 hours, until potatoes are very tender.
Use a potato masher to gently mash some of the potatoes for a thicker texture.
Stir in heavy cream and milk.
Whisk in the cornstarch slurry and cook on high for 20–30 minutes until creamy and thickened.
Taste and adjust seasoning as needed. Serve warm with optional garnish.

Notes

For thicker soup, mash more potatoes or simmer uncovered for a few extra minutes after adding cornstarch.
To keep it lighter, use 2% milk and skim dairy or swap in half-and-half.
Ensure your broth is gluten-free if you need a gluten-free dish.
Leftovers refrigerate well for up to 4 days; reheat gently.
