Zuppa Toscana: Creamy Sausage, Potato, and Kale Soup

This Zuppa Toscana recipe builds deep savory flavor in layers: crisp bacon, browned Italian sausage, softened fennel and onion, and Parmigiano-Reggiano rinds simmered directly in the broth. Russet potato and heavy cream give the soup a rounded, creamy body without a flour-thickened base.

Lacinato kale brings a sturdy green bite, while a final spoonful of sherry vinegar keeps the richness in balance. The result is hearty enough for a main course but still lively through the last spoonful.

How to Make Zuppa Toscana

1. Cook the bacon and brown the sausage. Cook the bacon in a Dutch oven until crisp, 10 to 12 minutes. Use a slotted spoon to transfer the bacon to paper towels and reserve it for serving, leaving 2 tablespoons bacon drippings in the pot. Add the sausage and cook, breaking it into bite-size pieces with a wooden spoon, until browned, 5 to 7 minutes. Transfer the sausage to a medium bowl and leave the resulting drippings in the pot for the aromatics.
2. Build the broth and cook the potato. Add the onion, fennel, garlic, fennel seeds, black pepper, and crushed red pepper to the Dutch oven. Cook until softened, 6 to 8 minutes. Add the chicken broth, water, potato, Parmigiano-Reggiano rinds, and salt. Bring to a simmer and cook until the potato is almost tender, 4 to 6 minutes.
3. Finish and serve. Add the kale and reserved sausage. Simmer until the kale is wilted and tender, 3 to 5 minutes. Remove the Dutch oven from the heat and stir in the heavy cream and sherry vinegar. Remove and discard the cheese rinds. Use a ladle to divide the soup among six bowls, top with the reserved bacon, garnish with black pepper, crushed red pepper, grated Parmigiano-Reggiano, and fennel fronds, and drizzle with extra-virgin olive oil.

For a coordinated finish, the 18-Piece Non Stick Ceramic Pots and Pans Set - Dog Paw Handle includes a 5QT stock pot for holding and serving the soup.

Practical Tips

• Let the meat brown. Give both the bacon and sausage enough time against the hot pot to develop savory color before moving to the aromatics.
• Cut uniform potatoes. Keep the russet potato pieces close to 3/4 inch so they approach tenderness at the same rate.
• Adjust salt late. The cheese rinds season the broth as they infuse, so taste after simmering before deciding whether the soup needs more salt.
• Finish off the heat. Stir in the heavy cream and sherry vinegar only after removing the Dutch oven from the burner to preserve a smooth broth and the vinegar's brightness.

Make-Ahead and Storage

Advance preparation may be refrigerated for up to one day according to the source. When cooking resumes, its note calls for adding the potatoes and kale during warm-up and waiting until the final finish for the heavy cream and sherry vinegar. Because the first session has no defined end point, this make-ahead variation requires kitchen testing and editorial approval before it can be treated as a complete procedure.

Frequently Asked Questions

Should I use mild or hot Italian sausage?

Either works in this recipe. Mild sausage keeps the heat restrained, while hot sausage makes the finished soup more assertive.

What is lacinato kale?

Lacinato kale is a dark, narrow-leaf kale with a sturdy texture that softens as it simmers in the soup.

Are the Parmigiano-Reggiano cheese rinds eaten?

No. They infuse the broth as it simmers, then should be removed and discarded before the soup is divided among the bowls.

Why is the sherry vinegar added off the heat?

Adding it after the pot leaves the heat preserves its bright acidity, which balances the sausage, bacon, cheese, and cream.
