Why You’ll Love This Slow Cooker Zuppa Toscana (Turkey Sausage & Beef Bacon Base)
- One-pot convenience: The slow cooker does the heavy lifting, meaning you only have one pot to wash at the end of the night. No splattered stovetops or multiple pans to scrub.
- Make-ahead friendly: You can prep the sausage and bacon the night before, store them in the fridge, and simply toss everything into the slow cooker the next morning before work.
- Budget-conscious ingredients: This soup relies on affordable staples like potatoes, kale, and tinned stock, making it a wallet-friendly option for feeding a hungry family.
- Freezer-friendly portions: The soup freezes beautifully without the cream and kale, so you can stash individual portions for those evenings when cooking is simply off the table.
- Crowd-approved flavours: Friends always ask me for this recipe after trying it at dinner parties. The combination of turkey sausage and beef bacon creates a deep, savoury base that rivals any restaurant version.
Ingredients You’ll Need
- 1 tablespoon olive oil
- 450g turkey sausages (mild or spicy, casings removed)
- 200g beef bacon, diced into small pieces
- 1 large onion, finely chopped
- 4 cloves garlic, minced
- 1 litre chicken stock (preferably low-sodium)
- 800g waxy potatoes (such as Maris Piper or Yukon Gold), peeled and cut into 2cm cubes
- 1 teaspoon dried oregano
- ½ teaspoon red pepper flakes (optional, for heat)
- 1 teaspoon sea salt
- ½ teaspoon black pepper
- 300ml double cream
- 150g kale, stems removed and leaves roughly torn
- Freshly grated Parmesan cheese, for serving
Tip: Waxy potatoes hold their shape during the long simmer, so avoid starchy varieties like King Edward or baking potatoes, which will break down into mush.
How to Make Slow Cooker Zuppa Toscana (Turkey Sausage & Beef Bacon Base)
- Brown the turkey sausage: Heat the olive oil in a large frying pan over medium-high heat. Add the turkey sausage meat, breaking it apart with a wooden spoon. Cook until it is no longer pink and you hear a steady sizzle, about 6–8 minutes. The meat should look golden brown and smell wonderfully savoury. Transfer it to the slow cooker insert.
- Cook the beef bacon: In the same pan, add the diced beef bacon. Cook over medium heat, stirring occasionally, until the pieces are crisp and the fat has rendered, roughly 5 minutes. You will see the bacon turn a deep reddish-brown and hear it crackling. Spoon the bacon into the slow cooker, leaving about a tablespoon of the rendered fat in the pan.
- Sweat the aromatics: Reduce the heat to medium-low and add the chopped onion to the pan. Cook, stirring often, until the onion becomes translucent and soft, about 4 minutes. Scrape up any browned bits from the bottom of the pan — those bits are pure flavour. Add the minced garlic and cook for another 30 seconds until you can smell its fragrance.
- Deglaze with stock: Pour about 200ml of the chicken stock into the pan and stir vigorously, scraping the bottom to lift all the caramelised bits. This liquid gold should look dark and smell deeply of roasted meat and onion. Pour this mixture into the slow cooker.
- Add remaining stock and potatoes: Pour the rest of the chicken stock into the slow cooker. Add the cubed potatoes, dried oregano, red pepper flakes (if using), salt, and pepper. Stir everything together until well combined. The liquid should just cover the potatoes.
- Slow cook: Place the lid on the slow cooker and cook on low for 6 hours or on high for 3 hours. After this time, the potatoes should be tender when pierced with a fork, and the broth will smell rich and aromatic. Do not lift the lid during cooking unless absolutely necessary — each peek adds 20 minutes to the cooking time.
- Add the cream and kale: In the last 15 minutes of cooking, stir in the double cream and the torn kale leaves. Replace the lid and let it cook for a further 10–15 minutes. The kale will soften and turn a vibrant, deep green, and the cream will turn the broth a pale, creamy ivory colour. Taste the soup and adjust the seasoning with extra salt and pepper if needed.
- Serve: Ladle the soup into warm bowls and top each portion with a generous sprinkle of freshly grated Parmesan cheese. Serve immediately with crusty bread or a simple side salad.
Tips From My Kitchen
- Brown the meat properly: Do not skip the browning step. The Maillard reaction that occurs when you sear the turkey sausage and beef bacon creates deep, savoury notes that no amount of seasoning can replicate. If you rush this step, your soup will taste flat.
- Cut potatoes to a uniform size: Aim for 2cm cubes so every piece cooks evenly. If some chunks are larger than others, you will end up with a mix of mushy and undercooked potatoes in your bowl.
- Add cream at the end: Pouring double cream in at the start of cooking can cause it to curdle or separate during the long simmer. By adding it during the final 15 minutes, you get a silky, luscious texture without any unpleasant graininess.
- Use low-sodium stock: Turkey sausage and beef bacon both contain plenty of salt, so using low-sodium chicken stock gives you control over the final seasoning. You can always add more salt at the table, but you cannot take it away.
- Prep the kale properly: Kale stems are tough and fibrous, so take the extra minute to strip the leaves from the stems before tearing them. This ensures every bite is tender and pleasant, not chewy or woody.
- Thicken the soup if desired: If you prefer a thicker broth, mash a few of the cooked potatoes against the side of the slow cooker with a fork before adding the cream. The starch will naturally thicken the liquid without needing any flour or cornflour.
Equipment You’ll Need
- Slow cooker (5–6 quart capacity)
- Large frying pan or skillet
- Sharp knife and cutting board
- Wooden spoon or spatula
- Measuring cups and spoons
- Ladle for serving
Common Mistakes to Avoid
- Overcrowding the pan: When browning the turkey sausage and beef bacon, work in batches if necessary. If you crowd the pan, the meat will steam instead of sear, leaving you with grey, flavourless protein rather than beautifully browned pieces. Give each piece space to make direct contact with the hot pan.
- Wrong temperature setting: Cooking this soup on high for the entire duration can cause the potatoes to break apart and the cream to separate when you add it later. Stick to the low setting for the best texture, or use high only if you are truly short on time and accept slightly softer potatoes.
- Skipping the rest time: Allow the soup to sit in the slow cooker on the warm setting for 5 minutes after adding the cream and kale. This brief rest lets the flavours meld together and ensures the kale has fully wilted without becoming slimy.
Delicious Variations to Try
- Spicy Version: Use hot turkey sausages instead of mild, and increase the red pepper flakes to a full teaspoon. You can also add a finely chopped jalapeño (seeds removed unless you want serious heat) when you sweat the onions for an extra layer of warmth.
- Vegetarian/Vegan Option: Replace the turkey sausage with a plant-based Italian sausage alternative and use smoked tempeh bacon in place of the beef bacon. Swap the chicken stock for a good-quality vegetable stock, and use full-fat coconut milk or a thick cashew cream instead of double cream. The coconut milk adds a subtle sweetness that works beautifully with the potatoes and kale.
- Different Protein: If you cannot find turkey sausage, you can use chicken sausages or even ground chicken seasoned with fennel seeds, garlic powder, and a pinch of smoked paprika. For the beef bacon, thick-cut beef brisket bacon or even diced smoked turkey works wonderfully.
What to Serve With Slow Cooker Zuppa Toscana (Turkey Sausage & Beef Bacon Base)
- Crusty sourdough bread or warm ciabatta rolls for dipping
- A simple green salad with a lemon vinaigrette to cut through the richness
- Roasted asparagus or broccoli drizzled with olive oil
- A side of Cheesy Beef Quesadillas Quick Weeknight Dinner for those who want extra protein on the side
- For a lighter option, pair it with Steak Salad With Blue Cheese Crispy Onions

Frequently Asked Questions
Can I use frozen kale instead of fresh?
Yes, you can use frozen kale, but add it directly to the slow cooker without thawing. Keep in mind that frozen kale will release extra water, so your soup may be slightly thinner. If this happens, just simmer it on the stovetop for a few minutes after adding the cream to let it reduce.
How do I store leftovers and reheat them?
Store leftovers in an airtight container in the refrigerator for up to four days. Reheat gently on the stovetop over medium-low heat, stirring occasionally, until piping hot. Alternatively, microwave individual portions in 30-second bursts, stirring between each, to avoid the cream separating.
Can I freeze this soup?
Absolutely, but freeze it before adding the cream and kale. When you are ready to eat, thaw the base in the refrigerator overnight, then reheat it on the stovetop. Stir in the double cream and kale during the last 15 minutes of reheating for the best texture and flavour.
What can I use instead of double cream?
For a lighter option, use single cream or full-fat coconut milk. If you want a dairy-free version, a blend of cashew cream (soaked cashews blended with water) and a splash of unsweetened oat milk provides a similar richness without the dairy.
Why did my soup turn out watery?
Watery soup usually means the potatoes were cut too small and broke down completely, or the slow cooker was set too high. To fix it, mash a few of the remaining potato chunks against the side of the pot to release their starch, then let the soup simmer uncovered for 10 minutes to thicken.
