Instructions
Rinse and scrub the potatoes, then cut them into bite-sized ½-inch cubes. Peel and dice the onion, remove the kale stems and roughly chop the leaves, and measure out the broth and cream.
Heat olive oil in a large pot or Dutch oven over medium heat. Add the Italian sausage, break it into small pieces with a wooden spoon, and cook for 5 to 7 minutes until browned and no longer pink. Spoon out excess fat, leaving about 1 tablespoon behind.
Add the diced onion to the pot and stir to coat in the drippings. Cook for 3 to 4 minutes, stirring often, until softened and translucent, scraping up any browned bits from the bottom.
Add the cubed potatoes and stir to combine. Pour in the chicken broth, making sure the potatoes are fully submerged. Bring to a boil, then reduce heat to low, cover, and simmer for 10 to 12 minutes until the potatoes are fork-tender.
Pour in the heavy cream and stir gently. Add the chopped kale and stir until mixed in. Simmer uncovered for 3 to 5 minutes until the kale wilts and the soup thickens slightly, keeping the heat low so the cream does not boil. Season with salt and black pepper to taste.
Ladle the hot soup into bowls and garnish with black pepper or grated Parmesan if desired. Serve right away.
Notes
Choose the right sausage: Mild Italian sausage is great for a family-friendly flavor, while spicy sausage adds a nice kick.
Cut potatoes evenly: Uniform ½-inch cubes cook at the same rate, so you avoid mushy or undercooked pieces.
Do not skip the kale: It adds texture and nutrients, but do not overcook it. It should be tender, not soggy.
Adjust the creaminess: For a thicker soup, reduce the chicken broth to 3½ cups or mash a few potatoes with a potato masher before adding the cream.
Taste as you go: Sausage and broth are already salty, so season gradually and taste before serving.
Storage: Store in an airtight container in the fridge for up to 4 days. Freeze in freezer-safe containers for up to 3 months, then thaw overnight in the fridge before reheating.
Reheating: Warm on the stovetop over medium heat, stirring occasionally. Add a splash of chicken broth if it thickens too much, and avoid boiling so the cream does not curdle.
Slow cooker method: Brown the sausage and sauté the onion first, then add to a slow cooker with the potatoes and broth. Cook on low for 6 to 8 hours or on high for 3 to 4 hours, then stir in the cream and kale 15 minutes before serving.
Variations: Swap the sausage for turkey sausage or chorizo, use spinach or Swiss chard instead of kale, replace heavy cream with coconut milk for a dairy-free version, or add carrots, celery, or mushrooms for extra heartiness.
Make it gluten-free: This recipe is naturally gluten-free as long as your chicken broth and Italian sausage are gluten-free. Always check the labels.
