Ingredients You’ll Need

• 1.5 kg beef brisket or chuck roast, cut into 5-7 cm chunks
• 2 tablespoons neutral oil (such as rapeseed or sunflower)
• 2 large onions, roughly chopped
• 6 cloves garlic, finely chopped
• 3 dried ancho or guajillo chillies, stems and seeds removed
• 2 teaspoons ground cumin
• 2 teaspoons smoked paprika
• 1 teaspoon dried oregano
• 1 teaspoon ground coriander
• 500 ml good-quality beef stock
• 2 tablespoons tomato purée
• 2 bay leaves
• Salt and freshly ground black pepper, to taste
• Juice of 2 limes
• Small handful of fresh coriander, roughly chopped

Tip: For the most tender result, choose a well-marbled cut like chuck or brisket. The fat renders down during the long cooking, keeping the meat incredibly moist and flavourful. If you can’t find dried chillies, you can substitute with 2-3 tablespoons of ancho chilli powder, though the texture of the sauce will be slightly less complex.

How to Make Slow Cooker Shredded Beef Tacos

1. Prepare the dried chillies: Place the seeded chillies in a heatproof bowl and cover with boiling water. Leave them to soak for 15-20 minutes, until they are soft and pliable. You should be able to smell their sweet, smoky aroma as they rehydrate.
2. Sear the beef: Pat the beef chunks thoroughly dry with kitchen paper. This is crucial for a good sear. Heat the oil in a large, heavy-based frying pan or flameproof casserole dish over a high heat. Sear the beef in batches, without crowding the pan, until each piece is deeply browned on all sides. Listen for a vigorous sizzle; this builds the foundation of flavour. Transfer the browned meat to your slow cooker.
3. Cook the aromatics: Reduce the heat to medium and add the chopped onions to the pan. Cook for 5-7 minutes, stirring occasionally, until they are softened and translucent and the edges are just beginning to caramelise. The pan will smell sweet and savoury. Add the chopped garlic and cook for another minute until fragrant.
4. Bloom the spices: Add the ground cumin, smoked paprika, oregano, and ground coriander to the pan with the onions. Stir constantly for about 30 seconds to 1 minute. The spices will become aromatic and deepen in colour. Take care not to let them burn.
5. Build the sauce: Add the tomato purée and stir for a minute, then pour in the beef stock. Use a wooden spoon to scrape up any browned bits from the bottom of the pan. This deglazing step is packed with flavour. Transfer this whole mixture to the slow cooker.
6. Blend the chillies: Drain the softened chillies and add them to a small blender along with about 100 ml of their soaking water. Blitz until you have a smooth, thick purée. Pour this into the slow cooker. Add the bay leaves and a generous pinch of salt and pepper. Give everything a good stir.
7. Slow cook: Place the lid on your slow cooker and cook on low for 6-8 hours, or on high for 3-4 hours. The beef is ready when it is so tender it falls apart at the slightest prod of a fork. The liquid should be gently shimmering and the whole kitchen will be filled with a heady, rich scent.
8. Shred the beef: Using two forks, carefully shred the beef directly in the slow cooker. The meat should pull apart with almost no resistance. Stir the shredded beef through the cooking liquid. Taste and adjust the seasoning with salt, pepper, and the juice of two limes. The acidity from the lime will lift all the deep, earthy flavours.
9. Finish and serve: Stir through the fresh coriander just before serving. The beef will be glossy, dark, and utterly tender, swimming in a small amount of rich, savoury sauce. Serve immediately.

Tips From My Kitchen

• Don’t skip the searing step: I know it adds an extra pan to wash, but that deep browning is where the real flavour lies. The Maillard reaction creates hundreds of new flavour compounds that you simply cannot get from just dumping raw meat in the slow cooker. It transforms the beef from merely tender to genuinely delicious.
• Toast your whole spices for a deeper flavour: If you have whole cumin and coriander seeds, toast them in a dry pan for a minute or two until fragrant before grinding. This releases their essential oils and gives the dish a much more aromatic and nuanced profile. It is a small extra step with a big payoff.
• Control the heat level to your taste: The two ancho or guajillo chillies provide a mild, smoky warmth. For a spicier taco, add a dried chipotle chilli or a teaspoon of cayenne pepper along with the other spices. For a milder dish, stick to just the anchos and ensure you remove all the seeds and white pith.
• Let the beef rest before shredding: Once the cooking time is up, turn off the slow cooker and let the beef sit in its liquid for 15-20 minutes. This allows the fibres to relax and reabsorb some of the cooking juices, resulting in a more succulent texture rather than a dry, stringy shred.
• Skim the fat if you prefer a leaner filling: After cooking, the surface of the liquid may have a layer of rendered fat. If you prefer a less rich filling, simply use a large spoon or a fat separator to skim off the excess fat before you shred the beef. This is entirely optional and a matter of personal preference.
• Make it a full meal prep session: While the beef is cooking, you can quickly prepare all your toppings and accompaniments. Chop the onions, dice the tomatoes, make a quick salsa, and warm the tortillas. I often pair this with a batch of Cheesy Vegetable Quesadillas Recipe for a truly varied taco night spread.

What to Serve With Slow Cooker Shredded Beef Tacos

• Warm corn or flour tortillas, charred slightly on a gas flame or in a dry pan for a smoky flavour.
• A vibrant, fresh salsa verde or pico de gallo for a bright, acidic contrast.
• Crumbled feta or a dollop of soured cream to add a creamy, salty element.
• Thinly sliced radishes, fresh coriander leaves, and a squeeze of lime for a fresh crunch.
• Pickled red onions or jalapeños for a sharp, tangy kick.
• A side of Fresh Yogurt Parfait Recipe Breakfast is a surprising but delightful palate cleanser if you want something light and cool between tacos.

Notes

For best results, sear the beef in batches to avoid steaming. The dried chillies can be any combination of ancho or guajillo. Leftovers keep well for 3 days.
