I use kielbasa instead of Italian sausage because Polish sausage is superior. This is not up for debate. Every recipe on the internet for "chicken sausage kale soup" calls for Italian chicken sausage, and every single time I substitute Polish kielbasa and the soup is better. Smokier. Meatier. More flavourful. This is my hill and I will die on it with a bowl of soup in my hand.

Ingredients
1poundPolish kielbasa, sliced into coins450g
1tablespoonolive oil
1largeonion, diced
3clovesgarlic, minced
2mediumcarrots, diced
3mediumpotatoes, cubedYukon Gold or red
6cupschicken broth1.5L
1bunchkale, stems removed, leaves torn
1teaspoonItalian seasoning
Juice of half a lemon
1/4cupheavy creamoptional
Salt, pepper, red pepper flakes
Parmesan for serving
Method
Brown the Kielbasa
Heat olive oil in a large pot over medium-high heat. Add the kielbasa coins and cook 3-4 minutes per side until deeply browned. Transfer to a plate.
Build the Base
In the same pot with the kielbasa fat, add onion and carrots. Cook 4-5 minutes until softened. Add garlic, Italian seasoning, and red pepper flakes. Cook 1 minute. Scrape up all the brown bits.
Simmer
Add potatoes and chicken broth. Bring to a boil, reduce to a simmer, cook 15-18 minutes until potatoes are tender. Add kale and kielbasa. Cook 5 more minutes until kale wilts.
Finish
Squeeze in lemon juice. Stir in cream if using. Season with salt and pepper. Serve with parmesan.
Notes
Leftovers keep 4-5 days and taste better the next day. Reheat on the stovetop. If potatoes absorbed the broth, add a splash of water. Freezes well for 3 months, though potatoes may change texture slightly.
