5-Ingredient Slow Cooker Chicken Gnocchi Soup
After years of testing weeknight dinners, I’ve finally landed on a slow cooker recipe that delivers a creamy, hearty soup without the usual sink full of pans. This Slow Cooker Chicken Gnocchi Soup has become my go-to for those frantic evenings when everyone is hungry and I need dinner on the table with minimal fuss. I stumbled upon this combination by accident, and it’s been a hit ever since.
Recipe Overview

- Cooking Time: 4–6 hours on low or 2–3 hours on high
- Total Time: Approximately 4 hours 15 minutes to 6 hours 15 minutes
- Servings: 6–8 generous portions
- Difficulty: Easy (perfect for beginner cooks)
Why You’ll Love This Slow Cooker Chicken Gnocchi Soup
- One-Pot Wonder: Everything cooks in the slow cooker insert, meaning you only have one pot to wash at the end. No separate pan for sautéing or boiling.
- No-Fuss Prep: You simply toss in the ingredients, set the timer, and walk away. There’s no standing over a hot stove stirring a roux or watching a pot boil over.
- Make-Ahead Friendly: The soup base can be prepped the night before and stored in the fridge. In the morning, just tip it into the slow cooker and switch it on.
- Freezer-Ready: This soup freezes beautifully without the gnocchi. I often make a double batch and freeze half for an emergency dinner later in the month.
- Family-Approved Texture: The soft, pillowy gnocchi and tender shredded chicken create a satisfying mouthfeel that even picky eaters enjoy.
Ingredients You’ll Need
- 500g boneless, skinless chicken thighs (or breasts if you prefer)
- 1 large onion, finely diced (about 200g)
- 3 medium carrots, peeled and diced (about 150g)
- 3 celery sticks, diced (about 100g)
- 3 cloves garlic, minced
- 1 litre chicken stock (preferably low-sodium)
- 250ml double cream (or single cream for a lighter version)
- 1 teaspoon dried thyme
- 1 teaspoon dried rosemary
- ½ teaspoon black pepper
- 1 teaspoon salt (adjust to taste)
- 500g fresh potato gnocchi (found in the chilled pasta aisle)
- 100g fresh spinach, roughly chopped
- 2 tablespoons olive oil
- 2 tablespoons cornflour mixed with 3 tablespoons cold water (for thickening)
Tip: If you’re prepping the night before, combine all the solid ingredients (chicken, onion, carrots, celery, garlic, and dried herbs) in a sealed container. Keep the stock, cream, and gnocchi separate until you’re ready to cook. This stops the vegetables from going soggy and the gnocchi from turning mushy.
How to Make Slow Cooker Chicken Gnocchi Soup
- Sauté the aromatics: Heat the olive oil in a large frying pan over a medium heat. Add the diced onion, carrots, and celery. Cook for 5–7 minutes, stirring occasionally, until the onions turn translucent and the carrots soften slightly. You’ll smell a sweet, savoury aroma as the vegetables release their moisture. Transfer them to the slow cooker insert.
- Add the chicken and stock: Place the chicken thighs directly into the slow cooker on top of the sautéed vegetables. Pour in the chicken stock, then sprinkle over the dried thyme, rosemary, salt, and pepper. Give everything a gentle stir to combine. The stock should just cover the chicken — if not, add a splash more water.
- Slow cook until tender: Cover the slow cooker with its lid and cook on low for 4–6 hours or on high for 2–3 hours. After 4 hours on low, the chicken should be fork-tender and easily shreddable. The broth will look clear and smell deeply of herbs.
- Shred the chicken: Using two forks, carefully remove the chicken thighs from the slow cooker and place them on a cutting board. Shred the meat into bite-sized pieces. You’ll see the fibres separate easily — the chicken should be so tender it almost falls apart on its own. Return the shredded chicken to the slow cooker.
- Thicken the broth: In a small bowl, whisk the cornflour with the cold water until smooth and free of lumps. Pour this slurry into the slow cooker and stir well. Let it cook uncovered for 10 minutes on high. The broth will change from a thin, watery consistency to a slightly glossy, velvety texture that coats the back of a spoon.
- Add the cream and gnocchi: Pour in the double cream and stir gently. Add the fresh gnocchi directly into the soup. Stir once more, then cover the slow cooker. Cook on high for a further 15–20 minutes. The gnocchi will float to the surface when they’re cooked — they should be soft and pillowy, not dense or chalky.
- Finish with spinach: Turn off the slow cooker. Add the chopped spinach and stir it through the hot soup. The residual heat will wilt the spinach in about 2–3 minutes. You’ll see the bright green leaves soften and darken slightly. Taste the soup and adjust the salt and pepper if needed. Serve immediately in warmed bowls.
Tips From My Kitchen
- Add gnocchi at the end: Gnocchi is essentially potato dough, and it breaks down if cooked for too long. Always add it in the final 20 minutes of cooking. If you add it at the beginning, you’ll end up with a starchy, gluey mess rather than distinct, soft dumplings.
- Use chicken thighs for flavour: Chicken breasts work in a pinch, but thighs remain juicier and more forgiving during long slow cooking. They also release more natural gelatin into the broth, giving the soup a richer mouthfeel without extra cream.
- Don’t skip the sauté step: I know it adds an extra pan, but sautéing the vegetables before adding them to the slow cooker deepens their flavour. Raw carrots and celery can taste flat after hours in liquid. That initial browning brings out their natural sweetness and savoury notes.
- Thicken at the end: Cornflour loses its thickening power if cooked for too long. Add the slurry in the last 30 minutes of cooking, not at the start. The broth should be piping hot when you add it, so the starch granules can activate immediately.
- Make it a freezer meal: If you want to prep for later, combine all the ingredients except the cream, gnocchi, and spinach in a freezer-safe bag. Freeze flat for up to 3 months. On the day you want to cook, tip the frozen block into the slow cooker, add the stock, and cook on low for 6–8 hours. Add the cream, gnocchi, and spinach at the end as usual.
Common Mistakes to Avoid
- Overcrowding the pan during sauté: If you pile all the vegetables into the frying pan at once, they’ll steam rather than brown. Sauté in batches if necessary, or use a larger pan. You want the vegetables to develop golden edges, not sit in their own watery juice. A crowded pan also takes longer to cook, which throws off your timing.
- Wrong temperature setting: Cooking this soup on high for the entire time can cause the dairy to curdle and the gnocchi to disintegrate. Stick to low for the main cooking phase, then switch to high only for the final 20 minutes when adding the cream and gnocchi. Low and slow gives you tender chicken and a stable broth.
- Skipping the rest time after adding spinach: It’s tempting to serve immediately after adding the spinach, but letting it sit for 2–3 minutes off the heat allows the spinach to wilt evenly without becoming slimy. If you stir it in and serve straight away, you’ll get crunchy stems and unevenly wilted leaves.
Delicious Variations to Try
- Spicy Version: Add 1–2 finely chopped red chillies along with the garlic, or stir in 1 teaspoon of smoked paprika and ½ teaspoon of cayenne pepper when you add the stock. The heat cuts through the creaminess beautifully and adds a warming kick on cold evenings.
- Vegetarian/Vegan Option: Swap the chicken for 400g of firm tofu, cubed, and use a good-quality vegetable stock. Replace the double cream with 200ml of full-fat coconut milk or a thick cashew cream. The coconut milk adds a subtle sweetness that works surprisingly well with the herbs. For extra protein, add a tin of drained chickpeas.
- Different Protein: Try boneless, skinless turkey thighs instead of chicken for a slightly leaner option. Or use leftover roasted chicken from a Sunday dinner — just shred it and add it in the last 30 minutes of cooking. For a more robust flavour, consider using Beef Shawarma Bowls With Garlic Sauce as inspiration for seasoning, though you’d need to adjust the cooking time for beef.
What to Serve With Slow Cooker Chicken Gnocchi Soup
- Crusty bread: A thick slice of sourdough or a warm baguette is perfect for soaking up the creamy broth. Toast it lightly for extra crunch.
- A crisp green salad: The richness of the soup balances well with a simple side salad dressed with lemon juice and olive oil. Something with a sharp vinaigrette cuts through the cream.
- Roasted vegetables: If you want to add more to the meal, serve alongside Crispy Air Fryer Chicken Drumsticks for a protein-heavy dinner, or simply roast some broccoli and cauliflower tossed in olive oil and garlic.
- Garlic bread: A quick homemade garlic bread using a ciabatta loaf and butter mixed with minced garlic and parsley makes this soup feel like a special weekend treat, even on a Tuesday.

Frequently Asked Questions
Can I use dried gnocchi instead of fresh?
You can use dried gnocchi, but the texture will be firmer and less pillowy than fresh. Dried gnocchi also takes longer to cook, so add it 5–10 minutes earlier than you would fresh. Keep an eye on it and taste a piece to ensure it’s cooked through before serving.
How do I store leftovers and reheat them?
Store leftovers in an airtight container in the fridge for up to 3 days. The gnocchi will absorb some of the broth overnight, so the soup will be thicker the next day. To reheat, add a splash of milk or stock to loosen it, then warm gently on the hob or in the microwave. Avoid boiling, as this can cause the cream to separate.
Can I make this soup in an Instant Pot?
Yes, you can adapt this recipe for an Instant Pot. Use the sauté function to cook the vegetables and chicken, then add the stock and cook on high pressure for 15 minutes. Quick-release the steam, shred the chicken, then use the sauté function again to add the cream, gnocchi, and spinach. Cook for 3–4 minutes until the gnocchi floats.
Why did my soup turn out too thin?
A thin soup usually means the cornflour slurry wasn’t given enough time to activate, or the ratio was off. Ensure the soup is bubbling hot when you add the slurry, and let it cook uncovered for a full 10 minutes. If it’s still thin after that, mix another tablespoon of cornflour with cold water and stir it in, then cook for another 5 minutes.
Can I use frozen spinach instead of fresh?
Frozen spinach works, but you need to thaw it first and squeeze out as much water as possible. Frozen spinach contains a lot of excess moisture, which can thin out the soup and make it watery. Add it at the same stage as fresh spinach, but cook for 5 minutes longer to ensure it’s heated through.
