What is Zuppa Toscana?

Some key features of this classic soup include:
Hearty and Filling
The base of the soup is hearty chicken or vegetable broth loaded with potatoes, Italian sausage, and kale. All these ingredients come together to create a thick, chunky, and very filling soup. A bowl of zuppa toscana can stand alone as a complete meal.
Creamy Texture
Heavy cream is whisked into the soup, which gives it a rich, velvety, and creamy texture without being overly heavy or rich. The cream helps to tie all the flavors together.
Savory Flavors
Italian sausage and aromatics like garlic, onions, and Italian herbs infuse the broth with tons of savory flavor. There’s a subtle heat from red pepper flakes as well. Everything combines for a deeply flavorful and satisfying soup.

Traditional Ingredients in Zuppa Toscana
Here are the main ingredients found in most authentic recipes for zuppa toscana:
Potatoes
Russet or Yukon Gold potatoes form the hearty base of the soup. They are peeled and diced into 1-inch cubes then cooked until fork tender. The potatoes thicken the broth.
Italian Sausage
Spicy Italian sausage provides tons of robust flavor. It is cooked crumbled or removed from the casings and browned before adding to the soup.
Kale
Kale gives the soup some color and nutrients. Curly green or Lacinato kale is traditional but any variety works. The kale is chopped and added toward the end to briefly wilt in the hot broth.
Onions and Garlic
Aromatic onions and garlic build flavor in the base and round out the savory notes. They are cooked down before adding the broth.
Chicken or Vegetable Broth
The soup base is typically chicken broth but vegetable broth can be substituted to make it vegetarian. The broth provides the bulk of the volume.
Heavy Cream
Heavy cream adds luxurious richness and body to the soup. It is whisked in at the end and gently simmered to heat through.
Italian Herbs and Spices
Oregano, basil, thyme, rosemary, bay leaves, and crushed red pepper flakes add characteristic Italian flavor. Kosher salt and black pepper season as well.
Is Zuppa Toscana Traditionally Gluten-Free?
Authentic zuppa toscana is made using ingredients that do not naturally contain gluten. The main components of the soup are:
– Potatoes
– Sausage
– Greens like kale or spinach
– Onions and garlic
– Chicken or vegetable broth
– Heavy cream
– Italian herbs and spices
None of these core ingredients contain gluten. So in its traditional prepared form, zuppa toscana is inherently a gluten-free soup.
There are no ingredients derived from wheat, barley, rye or other gluten-containing grains in classic recipes. So the soup is safe for those with celiac disease or gluten sensitivity.
Potential Sources of Gluten
While the standard recipe does not call for gluten, there are some potential sources of gluten to watch out for:
Pasta
Some recipes add small pasta like ditalini or orzo to zuppa toscana. These wheat-based pastas contain gluten.
Bread crumbs
Occasionally bread crumbs are used to thicken the soup or add texture. Bread crumbs contain gluten if made from wheat bread.
Thickeners
Some cooks use flour or roux to help thicken and add body to the soup. Flour contains gluten unless it is a gluten-free variety.
Sausage
Most Italian sausage is gluten-free, but some brands add breadcrumbs or wheat flour. Check the labels to be sure.
Bouillon
Some commercial broths and bouillon cubes contain gluten as an additive. Look for gluten-free certified when buying broth.
Cross-contamination
Even if the ingredients are gluten-free, there is potential for cross-contamination during processing and manufacturing. This is a higher risk with commercial soup mixes.
