Ingredients
Soup:
- 4 large russet potatoes (peeled and diced into 1-inch cubes)
- 1 medium onion (finely chopped)
- 3 celery stalks (diced)
- 2 medium carrots (peeled and sliced)
- 4 cups chicken or vegetable broth
- 1 cup heavy cream
- 1 cup whole milk
- 3 cloves garlic (minced)
- 1 tablespoon Cajun seasoning (adjust to taste)
- 1 teaspoon smoked paprika
- 1/2 teaspoon dried thyme
- 1/4 teaspoon cayenne pepper (optional for extra heat)
- Salt and black pepper (to taste)
- 1/4 cup all-purpose flour (for thickening)
- 2 tablespoons unsalted butter
Optional Toppings:
- Shredded cheddar cheese
- Crumbled bacon
- Chopped green onions
- Sour cream
Instructions
1: Prepare the Ingredients
- Peel and dice the potatoes into uniform cubes to ensure even cooking.
- Chop the onions, celery, and carrots for a medley of aromatic vegetables that complement the creamy base.
- Mince the garlic and measure out your spices for quick access during the cooking process.
2: Assemble in the Slow Cooker
- In your slow cooker, combine the diced potatoes, onion, celery, carrots, garlic, Cajun seasoning, smoked paprika, thyme, cayenne pepper (if using), and a generous pinch of salt and black pepper.
- Pour the chicken or vegetable broth over the vegetables, ensuring they are fully submerged.
3: Cook Low and Slow
- Set your slow cooker to low for 6-8 hours or high for 4-5 hours. This slow cooking allows the flavors to meld beautifully and the potatoes to become tender.
4: Create the Creamy Base
- About 30 minutes before the cooking time ends, melt the butter in a small saucepan over medium heat. Whisk in the flour to create a roux, cooking for 1-2 minutes until it turns golden and smooth.
- Gradually whisk in the heavy cream and milk, stirring until the mixture thickens.
5: Blend and Combine
- Once the potatoes are tender, use an immersion blender to partially blend the soup directly in the slow cooker. This creates a creamy consistency while leaving some chunks for texture. (Alternatively, transfer a portion of the soup to a blender and puree it before returning it to the slow cooker.)
- Stir the thickened cream mixture into the soup, mixing thoroughly.
6: Adjust Seasonings
- Taste the soup and adjust the seasoning, adding more salt, pepper, or Cajun seasoning as needed.
7: Serve and Enjoy
- Ladle the soup into bowls and garnish with your favorite toppings like shredded cheddar, crumbled bacon, or chopped green onions. Serve hot with crusty bread or crackers.
Tips
- Choose the Right Potatoes: Russet potatoes work best for this recipe because of their high starch content, which contributes to the soup’s creamy texture.
- Customize the Spice Level: Adjust the Cajun seasoning and cayenne pepper to suit your heat tolerance.
- Roux First: If you’re short on time, you can prepare the roux in advance and refrigerate it until ready to use.
- No Cream? No Problem: Substitute heavy cream with coconut milk or half-and-half for a lighter version.
- Add Protein: For an extra hearty soup, add cooked chicken, sausage, or shrimp in the last hour of cooking.
Storage Instructions
- Refrigeration: Store any leftovers in an airtight container in the refrigerator for up to 4 days.
- Freezing: This soup can be frozen for up to 3 months. Allow it to cool completely before transferring to freezer-safe containers. Thaw overnight in the refrigerator before reheating.
- Reheating: Reheat gently on the stovetop over low heat, stirring occasionally to prevent curdling.
Variations
- Seafood Twist: Replace some of the broth with clam juice and add cooked shrimp or crab meat for a Cajun seafood chowder.
- Vegetarian Option: Use vegetable broth and omit the bacon garnish for a vegetarian-friendly version. Add mushrooms for extra umami.
- Loaded Baked Potato Soup: Top with classic baked potato fixings like sour cream, chives, and shredded cheese for a fun twist.
- Extra Veggies: Incorporate diced bell peppers, zucchini, or corn for more texture and flavor.
