# Zuppa Toscana (Creamy Sausage Potato Soup)

Zuppa toscana is a creamy Italian soup with spicy sausage, tender potatoes and kale. It is hearty, rich and a restaurant favorite you can make at home in one pot.

Cooking the sausage and bacon first builds a flavorful base, and the cream goes in last for a silky finish. Serve with crusty bread for a full meal.

## Ingredients

- 500 g Italian sausage, mild or hot, casings removed
- 4 slices bacon, chopped
- 1 large onion, diced
- 4 cloves garlic, minced
- 1/2 tsp red pepper flakes
- 6 cups chicken broth
- 700 g russet or Yukon Gold potatoes, sliced 1 cm thick
- 1 bunch kale, stems removed, leaves torn
- 1 cup heavy cream
- 1 tsp salt, or to taste
- 1/2 tsp black pepper
- Grated Parmesan, to serve

## Method

1. Cook the sausage in a large pot over medium-high heat for 6 to 8 minutes, breaking it up, until browned with no pink (160°F, 71°C). Move to a plate, leaving about 1 tbsp fat.
2. Add the bacon to the pot and cook 5 minutes, until crisp. Move to the plate with the sausage, leaving 1 tbsp fat.
3. Add the onion and cook 5 minutes, until soft and translucent. Add the garlic and red pepper flakes for 30 seconds.
4. Pour in the broth and scrape up the browned bits from the bottom. Add the potatoes.
5. Bring to a boil, then lower to a simmer. Cook 12 to 15 minutes, until the potato slices are tender but not falling apart.
6. Return the sausage and bacon to the pot. Add the kale and simmer 3 minutes, until bright green and just tender.
7. Lower the heat. Stir in the cream, salt and pepper and warm 2 minutes without boiling.
8. Taste and adjust the seasoning. Serve topped with Parmesan.

## Why it works

- Browning the sausage and bacon creates fond, the browned bits that flavor the whole broth.
- Potatoes release starch as they simmer, which gives the broth a thicker, creamier body.
- Kale added late stays green and keeps a little bite.
- Adding the cream at the end over low heat keeps it smooth and prevents it from curdling.

## The science

- **Fond is flavor.** When meat browns in a pot, it leaves behind a layer of caramelized, concentrated flavor called fond. Pouring in broth and scraping dissolves it into the soup. That layer gives the broth a deeper, meaty taste without extra ingredients.
- **Cream and heat.** Cream is more stable than milk because of its higher fat, but a hard boil can still make it separate or look greasy. Warming it gently at the end blends it into the broth, so the soup stays silky and unbroken.

## Tips

- Slice the potatoes evenly at 1 cm so they cook at the same pace.
- Leave some sausage fat in the pot because it carries the flavor.
- For a lighter soup, use half-and-half instead of cream.

## Mistakes to avoid

- Boiling after the cream goes in: it can separate, so keep the heat low.
- Overcooking the kale: it turns dull and soft, so add it for the last 3 minutes.
- Slicing the potatoes unevenly: some turn to mush while others stay hard, so cut them evenly.

## Variations and swaps

- Use hot Italian sausage for more heat.
- Replace the kale with spinach or Swiss chard.
- Add a splash of white wine after the onions.
- Swap heavy cream for coconut cream for a dairy-free version.
- Swap russet potatoes for Yukon Golds, which hold their shape better.

## Storage

Refrigerate within 2 hours for up to 4 days. Reheat gently to 165°F (74°C), stirring. Freezing is not recommended because the potatoes and cream turn grainy.

## FAQ

**What is zuppa toscana?**

Zuppa toscana is an Italian-American soup made with sausage, potatoes, kale and cream. It is popular from Olive Garden.

**Can I use spinach instead of kale?**

Yes. Spinach cooks faster, so add it in the last minute or two. Chard works as well.

**How do I thicken zuppa toscana?**

Mash a few potato slices against the side of the pot and simmer a few minutes longer. The released starch thickens the broth.

**Can I make zuppa toscana ahead?**

Yes. It keeps well in the fridge for up to 4 days. Add the cream when you reheat for the best texture.
