Storage/Reheating

Store leftovers in an airtight container in the fridge for up to 4 days. Reheat gently on the stove or in the microwave, stirring often. If soup thickens too much, add a splash of broth or cream to loosen it. This soup also freezes well—let it cool completely, store in freezer-safe containers, and freeze for up to 2 months. Thaw overnight in the fridge before reheating.

FAQs

What makes it “Cajun” potato soup?

The Cajun flavor comes from the blend of spices including paprika, garlic powder, onion powder, cayenne, and herbs that give the soup a bold, savory kick.

Can I make this soup vegetarian?

Yes, use vegetable broth and skip any meat add-ins. You can also use plant-based cream or milk alternatives.

Do I need to peel the potatoes?

Peeling is optional. Russet potatoes are best peeled for smooth texture, but Yukon gold can be left unpeeled for a rustic finish.

What’s the best kind of potato to use?

Russet potatoes break down for a creamier texture, while Yukon gold hold their shape better and add buttery flavor.

Can I make it in a slow cooker?

Yes. Sauté the veggies and roux first, then add everything except the cream to the slow cooker. Cook on low for 6–8 hours, stir in cream near the end.

Is Cajun seasoning spicy?

It has a mild to moderate heat level. Adjust the amount based on your spice preference.

How do I thicken the soup?

Mash some of the cooked potatoes or stir in a cornstarch slurry (1 tbsp cornstarch mixed with 2 tbsp cold water) near the end.

Can I blend the soup?

Yes, for a smoother soup, blend part or all of it using an immersion blender. Just be careful not to over-blend if you want some texture.

What proteins can I add?

Cooked sausage, shredded chicken, bacon, or even shrimp work well with the Cajun flavors.

Can I make this soup ahead of time?

Yes, it reheats beautifully and is great for meal prep or leftovers throughout the week.

Creamy Cajun Potato Soup brings together the heartiness of a traditional potato soup with the bold spices of Cajun cooking. It’s rich, cozy, and perfect for chilly nights or casual dinners. With endless ways to customize it, this flavorful one-pot meal is sure to become a staple in your kitchen.
