Ingredients
- 6 slices bacon
- 2 tablespoons unsalted butter
- ½ small onion, diced
- 2 large leeks (white parts only), cleaned and sliced
- ½ teaspoon smoked paprika
- ½ teaspoon kosher salt
- ¼ teaspoon black pepper
- 6 cloves garlic, minced
- 3 pounds petite red potatoes, cleaned and quartered
- 3 stalks celery, cleaned and diced
- 6 cups chicken stock
- ½ cup white wine
- ½ teaspoon fresh rosemary leaves, finely minced
- 1 teaspoon Cajun seasoning
- 1 cup heavy cream or milk
- 1 cup shredded cheddar cheese
- ¼ cup grated parmesan or romano cheese
- 1 pound hot Italian sausage (casings removed), cooked and crumbled
- Salt and pepper, to taste
- Chives, optional topping
Preparing Your Ingredients

Frying the Bacon
In a large Dutch oven, fry the bacon until it’s crispy. Don’t drain the bacon grease; it’s packed with flavor. Remove the bacon to a paper towel-lined plate and let it cool. Once cooled, crumble the bacon and reserve it for later. It will add a delicious crunch to your soup.
Sautéing the Aromatics
In the same pan, melt the butter over medium heat. Add the diced onions and leeks, sautéing for about 3-4 minutes until they start to soften beautifully. Incorporate the smoked paprika, kosher salt, black pepper, and garlic, cooking for an additional minute until fragrant. This step builds your flavor base, setting the stage for a delicious soup.
Transferring to the Crock Pot
Mixing the Base
Spray the inside of your crock pot with cooking spray. Then, transfer the onion and leek mixture into the crock pot. This mixture is packed with flavor and will infuse your soup with deliciousness.
Adding the Vegetables
Now it’s time to mix in the quartered potatoes, diced celery, chicken stock, white wine, minced rosemary, and Cajun seasoning. Stir everything together to combine thoroughly. Each ingredient plays its part, creating a delightful medley.
Cooking the Soup
Slow Cooking
Cover the crock pot and cook on low for 8 hours or on high for 4 hours until the potatoes are fork-tender. Just imagine the tantalizing aroma wafting through your home as it cooks.
Final Touches
Preparing the Sausage
In a skillet, cook the Italian sausage over medium heat until it’s browned and fully cooked, breaking it up as it cooks. Drain any excess grease and set aside. This sausage adds a hearty texture and a punch of flavor.
Blending the Soup
Once your soup is cooked, use an immersion blender to blend until you reach your desired texture. If you prefer a smoother soup, carefully transfer batches to a standard blender, blend, and return it to the crock pot. It’s a fun process, and seeing the transformation is so rewarding!
Adding Cream and Cheese
Now stir in the heavy cream and both types of cheese until melted and well integrated. Then, mix in the cooked sausage, adjusting seasoning with salt and pepper to taste. You’ll be amazed at how the creaminess elevates the overall dish.
Serving Suggestions
Serve your soup hot, garnished with crumbled bacon and fresh chives for a beautiful presentation. Every bowl looks inviting and delicious, making it hard to resist diving in.
Tips for Success
To ensure the best flavor, make sure your leeks are thoroughly cleaned to avoid any grit in your soup. Leeks often hide a little dirt, and cleaning them well will improve your soup.
Feel free to experiment with different types of cheese for varying flavors. Gruyere or mozzarella can certainly add a twist to this already scrumptious dish.
For a lighter version, you can easily substitute heavy cream with milk or a dairy-free alternative. It will still taste great, just a bit fresher.
Variations
You might consider adding different proteins, such as chicken or turkey sausage, for a variation in flavor. This can change the dynamics of your soup in a fun way!
If you like a little heat, incorporate red pepper flakes into the mix. It adds a kick that some might find delightful!
Storage Tips
Store any leftovers in an airtight container in the refrigerator for up to 3 days, or freeze for up to a month. That way, you can enjoy this delicious soup whenever you want!
Pairing Ideas
Serve alongside crusty bread or a fresh green salad for a complete meal experience. A nice piece of baguette can be perfect for dipping!

FAQs
1. Can I make this soup ahead of time?
Yes, this soup tastes even better when made a day in advance! Just reheat before serving; the flavors deepen overnight, making it even more delicious.
2. Is there a vegetarian option?
Absolutely! Omit the bacon and sausage, use vegetable broth, and consider adding more veggies or lentils for protein. You won’t be disappointed.

To thicken your soup, blend more of it with an immersion blender or add a cornstarch slurry (cornstarch mixed with water) during cooking. This can help achieve your preferred consistency.
4. Can I use frozen leeks or potatoes?
Yes, you can use frozen vegetables, but it may slightly alter the texture. Cooking times may also need adjustment, so keep an eye on it.
5. What other toppings do you recommend?
Consider croutons, sliced green onions, or a drizzle of olive oil for added flavor and texture. Each topping can really brighten the overall dish!
