How to Make this
1. Cook the bacon in a large Dutch oven or heavy pot over medium heat until crisp; remove bacon, chop, and reserve 1 tablespoon of bacon fat in the pot.
2. Add butter and olive oil to the pot with the reserved bacon fat, then brown the sliced andouille or kielbasa for 3 to 5 minutes until lightly caramelized; remove and set aside with the bacon.
3. Add the diced onion, celery, and green bell pepper to the pot and sauté over medium heat until softened, about 5 minutes; stir in the minced garlic and cook 30 seconds until fragrant.
4. Sprinkle the flour over the vegetables and cook, stirring, 1 to 2 minutes to remove the raw flour taste and form a light roux.
5. Gradually whisk in the chicken broth until smooth, then add the diced potatoes, bay leaf, dried thyme, smoked paprika, and 2 tablespoons Cajun seasoning; bring to a simmer.
6. Simmer gently until the potatoes are very tender, about 15 to 20 minutes; remove the bay leaf.
7. Use a potato masher or an immersion blender to lightly mash or purée about one third of the soup to thicken it while leaving plenty of chunky potato and vegetable pieces.
8. Stir in the heavy cream, whole milk, browned sausage, and chopped bacon; warm through over low heat without boiling. Taste and add additional Cajun seasoning, salt, and freshly ground black pepper as needed.
9. Remove from heat and stir in lemon juice if using. Serve topped with sliced green onions, shredded sharp cheddar, and chopped fresh parsley.

Pro Tips
1) Brown the sausage and bacon until they have a good color. Those caramelized bits add deep, savory flavor to the whole pot. Take them out, then use some of the rendered fat to cook the veg so nothing tastes flat.
2) When you add the flour, keep stirring and cook it long enough to lose the raw flour taste but not so long it browns too much. That light roux will thicken the soup without making it gluey. Whisk broth in slowly to avoid lumps.
3) For the best texture, mash only about one third of the potatoes by hand with a potato masher or pulse briefly with an immersion blender. That gives a creamy body while keeping plenty of chunky potato and vegetables for interest.
4) Finish gently and taste often. Heat the soup through on low after adding cream and milk and avoid boiling, which can separate dairy and dull the spices. Adjust Cajun seasoning and a splash of lemon juice at the end to brighten and balance the richness.
