Name: Hairy Bikers Slow Cooker Spanish Chicken Recipe
Prep time: 20 min
Cook time: 6 h
Total time: 6 h 20 min
Ingredients: 1 tbsp olive oil; 8 bone-in, skin-on chicken thighs; 200g Spanish chorizo sausage, sliced; 2 onions, sliced; 2 garlic cloves, crushed; 2 peppers (1 red, 1 yellow), sliced; 2 tsp smoked paprika; 1 x 400g tin chopped tomatoes; 120ml chicken stock; Salt and pepper

This rich, smoky Hairy Bikers slow cooker Spanish chicken is made with bone-in chicken thighs, chorizo, smoked paprika, and peppers. The chicken turns fall-apart tender after 6 hours on low, and the chorizo melts into a thick, deeply flavoured sauce. It serves 4 with just 20 minutes of hands-on prep.

I make this on Sunday mornings so it’s ready by the time the house gets hungry. It’s one of the few slow cooker recipes where the browning step actually matters, and you can taste the difference.

Why Does This Slow Cooker Spanish Chicken Work So Well?

The browning step. Most slow cooker recipes skip this. Searing the chicken thighs skin-side down for 3–4 minutes triggers the Maillard reaction. That golden crust adds a savoury depth to the sauce that raw chicken in a slow cooker simply cannot deliver.

Chorizo does double duty. When you fry the chorizo first, it renders out bright orange, paprika-infused oil. That oil becomes the cooking fat for the onions and peppers. It builds smoky flavour into every layer before the slow cooker even turns on.

Low and slow with thighs, not breasts. Chicken thighs have more connective tissue and fat than breasts. Over 6–8 hours on low, that connective tissue breaks down into gelatin. It thickens the sauce naturally and keeps the meat impossibly tender.

Controlled liquid. The recipe uses just one tin of tomatoes and 120ml of stock. The peppers and onions release their own water during cooking. Starting with less liquid means you end up with a thick, concentrated sauce, not a watery stew.

Hairy Bikers Slow Cooker Spanish Chicken Recipe

Slow Cooker Spanish Chicken Ingredients

1 tbsp olive oil
8 bone-in, skin-on chicken thighs
200g Spanish chorizo sausage, sliced
2 onions, sliced
2 garlic cloves, crushed
1 red pepper, deseeded and sliced
1 yellow pepper, deseeded and sliced
2 tsp smoked paprika
1 x 400g tin chopped tomatoes
120ml chicken stock
Salt and freshly ground black pepper, to taste

How to Make Slow Cooker Spanish Chicken

Brown the chicken: Heat the olive oil in a large frying pan over medium-high heat. Season the chicken thighs with salt and pepper and place them skin-side down. Brown for 3–4 minutes on each side until the skin is golden and crisp, working in batches if needed. Transfer the chicken to the slow cooker pot.
Fry the chorizo: Add the sliced chorizo to the same pan and fry for 2–3 minutes until it releases its bright orange, smoky oils. Transfer the chorizo to the slow cooker.
Cook the vegetables: In the leftover chorizo oil, add the sliced onions and peppers. Cook for 5–7 minutes until softened. Stir in the crushed garlic and smoked paprika and cook for one more minute until fragrant.
Combine in the slow cooker: Scrape the cooked vegetables and all the flavourful bits from the pan into the slow cooker. Pour in the tinned tomatoes and chicken stock. Stir everything together gently to combine.
Slow cook: Place the lid on the slow cooker. Cook on LOW for 6–8 hours or on HIGH for 3–4 hours, until the chicken is cooked through and falls apart easily.
Season and serve: Check the seasoning and add more salt and pepper if needed. Serve the Spanish chicken hot with its rich sauce.

What Are the Best Tips for Slow Cooker Spanish Chicken?

Pat the chicken dry first: Before seasoning, blot the thighs with kitchen paper. Dry skin sears faster and crisps up better in the pan. Wet skin steams instead of browning, and you lose that golden crust that flavours the whole sauce.
Check the internal temperature: Chicken thighs are done when they reach 74°C on a meat thermometer. In a slow cooker on LOW for 6–8 hours, they will easily pass this. It is worth checking if you cook on HIGH for a shorter time.
Use cured Spanish chorizo: Buy cured Spanish chorizo, not the fresh Mexican kind. Spanish chorizo is seasoned with smoked paprika, which gives the dish its signature smoky flavour. If you enjoy this chicken and chorizo pairing, try the Hairy Bikers chicken and chorizo recipe for a faster stovetop version.
If the sauce is too thick: Add a splash of stock or water in the last 30 minutes to loosen it. If it is too thin, remove the lid and switch to HIGH for the final hour to let excess liquid cook off.
Add olives for a traditional touch: Stir in 100g pitted green olives in the last hour of cooking. They add a briny, salty flavour that is classic in Spanish stews and pairs perfectly with the smoky chorizo.

Prefer an oven tray bake? The Hairy Bikers Mediterranean chicken tray bake uses similar Mediterranean flavours but roasts everything in one tin.

What to Serve with Spanish Chicken?

The thick, smoky sauce is built for soaking up. Serve it over a bed of fluffy basmati or long grain rice to catch every drop. Crusty sourdough or ciabatta bread works just as well for mopping up the sauce.

For a lighter side, pair it with a simple green salad dressed in a sharp vinaigrette. Buttery mashed potatoes or roasted new potatoes also work well alongside. For more slow cooker ideas, check the best slow cooker recipes collection.

How Do You Change Up This Recipe?

Add beans: Stir in a drained 400g tin of cannellini beans or butter beans in the last hour of cooking. They bulk out the stew and soak up the smoky sauce.
Use wine: Replace the 120ml chicken stock with dry white wine for a richer, slightly sharper sauce. The alcohol cooks off during the long slow cook.
Swap the peppers: Use courgette chunks or roasted red peppers from a jar instead. Both soften nicely in the slow cooker without going mushy.
Add potatoes: Toss in 300g halved new potatoes at the start of cooking. They absorb the sauce and turn this into a complete one-pot meal with no side dishes needed.

How to Store Spanish Chicken Leftovers?

Let the chicken cool completely, then transfer to an airtight container. It keeps in the fridge for up to 3 days. The flavours often taste even better the next day once everything has had time to settle.

This dish freezes well. Portion it into freezer-safe bags or containers once cooled and freeze for up to 3 months. Thaw overnight in the fridge and reheat gently on the hob or in the microwave until piping hot.

Frequently Asked Questions

Can I use chicken breast instead of thighs? You can, but thighs are strongly recommended. Breasts dry out over long cook times, so add them to the slow cooker for only the last 2–3 hours on LOW.

What if I don’t have a slow cooker? Use a large, heavy-bottomed pot or Dutch oven with a tight-fitting lid. Follow the browning steps in the pot, then cover and cook on very low heat on the hob for 1.5–2 hours.

Is this the same as the Hairy Bikers Spanish chicken bake? No, the original is a Spanish-style chicken bake cooked at 200°C with fresh tomatoes and new potatoes. This is a slow cooker adaptation with tinned tomatoes, stock, and a much longer cook time.

What size slow cooker do I need? A 4–6 litre slow cooker works best for this recipe. The 8 chicken thighs, chorizo, and vegetables need enough room to sit in a single layer or close to it.

How long does chicken take in a slow cooker? Bone-in chicken thighs take 6–8 hours on LOW or 3–4 hours on HIGH to become fall-apart tender. Always check they have reached an internal temperature of 74°C before serving.
