What if you could make a rich, creamy, restaurant-quality soup at home — with more protein, less fat, and almost no effort?
That’s what this high-protein crockpot zuppa toscana soup delivers.
Zuppa Toscana is a classic Italian soup that’s creamy, savory, and packed with sausage, potatoes, and kale. But the Olive Garden version is heavy on cream and light on protein. This version uses a creamy broth with less cream and adds extra Italian sausage for a protein boost.
Each serving packs 32g of protein from the sausage, bacon, and broth. It’s the kind of soup that warms you up from the inside out and keeps you full for hours.
The best part? It’s set-it-and-forget-it easy. Brown the sausage, layer everything in the crockpot, and come back to a rich, hearty soup that tastes like it’s been simmering all day.
If you’re looking for a cozy, protein-packed dinner that everyone will love, this crockpot zuppa toscana soup belongs in your regular rotation.
Let’s make this happen.

Zuppa Toscana Soup Crockpot
Rich, creamy, and packed with sausage, bacon, potatoes, and kale — a restaurant-quality soup made easy in your slow cooker.
Ingredients
- 1½ lbs Italian sausage (mild or spicy), casings removed
- 6 slices bacon, chopped
- 1 onion, diced
- 4 cloves garlic, minced
- 4 cups low-sodium chicken broth
- 2 lbs Yukon Gold potatoes, cubed (about 4-5 medium)
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon dried oregano
- ½ teaspoon red pepper flakes (optional)
- 4 cups chopped kale (stems removed)
- 1 cup heavy cream (or half-and-half)
- ½ cup grated Parmesan cheese
- Fresh parsley for garnish
Instructions
- In a large skillet over medium-high heat, cook the Italian sausage and bacon, breaking up the sausage as it browns, for about 6-8 minutes. Use a slotted spoon to transfer the sausage and bacon to the slow cooker. Leave a little of the drippings in the pan.
- Add the diced onion and garlic to the skillet and cook for 2-3 minutes until softened and fragrant. Transfer to the slow cooker.
- Add the chicken broth, cubed potatoes, salt, pepper, oregano, and red pepper flakes (if using) to the slow cooker. Stir to combine.
- Cover and cook on LOW for 6-7 hours or on HIGH for 3-4 hours, until the potatoes are tender.
- Stir in the chopped kale and heavy cream. Cover and cook on HIGH for 15-20 minutes, until the kale has wilted.
- Stir in the Parmesan cheese. Taste and adjust seasoning with salt and pepper.
- Serve hot, garnished with fresh parsley.
Notes
Quick Tip
Add the kale at the end. Kale only needs 15-20 minutes to wilt. Adding it too early makes it mushy and dull. Stir it in during the last 20 minutes for the best texture and color.
Tips
Use spicy Italian sausage. It adds a nice kick that cuts through the creamy broth. For a milder version, use sweet or mild Italian sausage.
Cube the potatoes evenly. This ensures they cook at the same time. Aim for ½-inch to ¾-inch cubes.
Don’t skip the bacon. Bacon adds a smoky depth that makes this soup taste as if it came from a restaurant.
Use Yukon Gold potatoes. They hold their shape better than russets and have a creamy texture that works beautifully in soup.
Add the cream at the end. Adding cream too early can cause it to curdle. Stir it in during the last 15-20 minutes of cooking.
Taste before serving. Different sausages have different salt levels. Taste and adjust seasoning before serving.
Serving Suggestions
This soup is a complete meal on its own, but here are a few ideas:
- With crusty bread — for sopping up every drop
- With a side salad — a simple green salad with vinaigrette balances the richness
- With garlic bread — the perfect pairing for a cozy dinner
Storage and Meal Prep
Fridge: Keeps in an airtight container for up to 4 days. The flavors deepen overnight.
Reheat: Gently on the stovetop over medium-low heat or in the microwave. Add a splash of broth or milk if it has thickened too much.
Freezer: This soup freezes well for up to 3 months. Thaw overnight in the fridge and reheat gently. The potatoes may soften slightly, but the flavor remains delicious.
Meal prep: Portion into containers for grab-and-go lunches all week.
Recipe Variations
Low-carb version. Swap the potatoes for cauliflower florets. Add them in the last hour of cooking so they don’t get mushy.
Lighter version. Use turkey sausage instead of pork sausage, and use half-and-half instead of heavy cream.
Dairy-free version. Use coconut cream instead of heavy cream and omit the Parmesan (or use a dairy-free alternative).
Gluten-free version. This recipe is naturally gluten-free — just make sure your sausage and broth are certified GF.
Vegetarian version. Use plant-based Italian sausage and vegetable broth. Add extra beans for protein.
Add more vegetables. Add sliced mushrooms with the onion, or throw in a handful of spinach at the end.
Frequently Asked Questions
What is Zuppa Toscana?
Zuppa Toscana is a creamy Italian soup made with sausage, bacon, potatoes, and kale. It’s a popular menu item at Olive Garden and a favorite for cozy nights at home.
Can I make this crockpot zuppa toscana soup on the stovetop?
Yes. After browning the sausage, add the remaining ingredients (except the kale, cream, and Parmesan). Simmer for 20-25 minutes until the potatoes are tender. Stir in the kale, cream, and Parmesan and cook for 5 more minutes.
Can I use a different type of potato?
