Slow Cooker Zuppa Toscana Soup is a rich, comforting Italian-style soup packed with flavor and heartiness. Inspired by the beloved Olive Garden favorite, this version features crumbled Italian sausage, tender potatoes, curly kale, onions, garlic, and a creamy broth—all slow-cooked to perfection. The beauty of using a crockpot is that it allows all the flavors to develop deeply while keeping the preparation simple and hands-off. It’s the ultimate cozy meal for cold days, family dinners, or meal prepping for the week. With its blend of savory meat, creamy texture, and vibrant greens, this soup is as satisfying as it is easy.
Ingredients
- 1 pound Italian sausage (mild or spicy)
- 5 cups russet potatoes, diced (peeled or unpeeled)
- 1 small yellow onion, finely chopped
- 3 cloves garlic, minced
- 6 cups low-sodium chicken broth
- 1 teaspoon Italian seasoning
- ½ teaspoon crushed red pepper flakes (optional)
- Salt and black pepper, to taste
- 1 cup heavy cream
- 4 cups chopped fresh kale (or spinach)
- Optional: ½ cup grated Parmesan cheese (for serving)
Preparation
Step 1:
In a skillet over medium heat, brown the Italian sausage until fully cooked. Use a spatula to break it into crumbles as it cooks. Drain excess grease and transfer the sausage to the slow cooker.
Step 2:
Add diced potatoes, chopped onion, minced garlic, chicken broth, Italian seasoning, red pepper flakes (if using), salt, and black pepper to the slow cooker. Stir to combine.
Step 3:
Cover and cook on low for 6–7 hours or on high for 3–4 hours, until the potatoes are tender.
Step 4:
Stir in the heavy cream and chopped kale. Cover again and cook on high for an additional 15–20 minutes, or until the kale is wilted and the soup is heated through.
Step 5:
Taste and adjust seasonings as needed. Serve hot with grated Parmesan and crusty bread if desired.
Variation
- Use turkey or chicken sausage for a lighter version.
- Substitute spinach for kale if you prefer a milder green.
- Add cooked bacon or pancetta for an extra smoky layer of flavor.
- Use coconut milk instead of cream for a dairy-free option.
- Mix in cannellini beans for added protein and texture.
Cooking Note
For a thicker soup, mash a few of the cooked potatoes against the side of the slow cooker before adding the cream. If using pre-cooked sausage or a lean variety, you can skip the browning step and add it directly to the crockpot. Stir the soup well after adding the cream to ensure a smooth and velvety finish.
Serving Suggestions
Serve Slow Cooker Zuppa Toscana Soup with a warm slice of garlic bread or a crusty baguette for dipping. It also pairs well with a crisp green salad tossed in Italian dressing. For a full Italian-inspired meal, serve this soup as a starter followed by a simple pasta dish or baked lasagna. Garnish with extra red pepper flakes, Parmesan cheese, or a drizzle of olive oil before serving.
