A creamy, hearty soup with spicy Italian sausage, tender potatoes, and fresh kale. This restaurant-style copycat is pure comfort in a bowl and ready in just 40 minutes!
Place a large pot or Dutch oven over medium-high heat. Add the spicy Italian sausage. Use a spoon to break it apart and cook until browned and cooked through, about 5-7 minutes.
Add the minced garlic and optional red pepper flakes. Cook for 1 more minute, stirring constantly, until fragrant.
Pour in the chicken broth, scraping up any browned bits from the bottom of the pot. Add the sliced potatoes.
Bring the soup to a boil, then reduce the heat to a medium-low simmer. Let it cook for 10-15 minutes, or until the potatoes are tender when pierced with a fork.
Add the chopped kale. Stir into the hot soup and let it wilt, which will only take 2-3 minutes.
Turn the heat to low. Slowly pour in the heavy cream and stir to combine. Let the soup warm through for another 2-3 minutes, but do not let it come to a boil.
Taste the soup and add salt and pepper as needed.
Ladle into bowls and serve hot, garnished with grated Parmesan cheese if desired.
Notes
For an extra layer of flavor, cook 4 slices of chopped bacon in the pot before the sausage. Remove the bacon with a slotted spoon and save for topping. Cook the sausage and onion in the reserved bacon fat.
