Step 1: Prepare the Ingredients

1. Slice the Sausage: Cut the smoked sausage or kielbasa into bite-sized rounds. Set aside.
2. Dice the Potatoes: Peel and chop the potatoes into 1-inch cubes for even cooking.
3. Chop the Onion and Garlic: Finely dice the onion and mince the garlic cloves.

Step 2: Cook the Sausage

1. Sauté the Sausage: Heat a large pot or Dutch oven over medium heat. Add the sliced sausage and cook for 5-7 minutes, stirring occasionally, until browned and slightly crispy. Remove the sausage with a slotted spoon and set aside, leaving the rendered fat in the pot.

Step 3: Sauté the Aromatics

1. Sauté the Onion and Garlic: Add the butter to the pot. Once melted, add the chopped onion and garlic. Cook for 3-4 minutes until softened and fragrant.

Step 4: Build the Base

1. Create the Roux: Sprinkle the flour over the sautéed onions and garlic, stirring constantly for 1-2 minutes to create a roux.
2. Add the Broth: Gradually whisk in the chicken broth, ensuring there are no lumps. Bring the mixture to a simmer.

Step 5: Cook the Potatoes

1. Simmer the Potatoes: Add the diced potatoes, thyme, smoked paprika, salt, and pepper to the pot. Simmer for 12-15 minutes, or until the potatoes are tender.

Step 6: Add Creaminess

1. Incorporate the Cream and Milk: Reduce the heat to low and stir in the heavy cream and milk. Let the mixture gently heat without boiling to avoid curdling.
2. Thicken the Chowder: Simmer for 5 minutes, allowing the flavors to meld and the chowder to thicken slightly.

Step 7: Finish the Chowder

1. Return the Sausage: Add the browned sausage back into the pot, stirring to combine.
2. Optional Add-Ins: If using corn or cheese, stir them in now and cook for an additional 2-3 minutes until heated through.

Step 8: Serve and Garnish

1. Garnish: Ladle the chowder into bowls and garnish with chopped parsley or chives for a fresh, colorful touch.
2. Serve: Serve hot with crusty bread or crackers for dipping.
