Slow cooked beef chilli tacos

Let the slow cooker do the work with these bold beef chilli tacos, packed with smoky spices, tinned kidney beans and a triple hit of chilli heat.

Delicious food doesn’t need to be showy or fancy. There’s nothing extravagant about my chilli con carne, but whacking everything in the slow cooker just elevates it to the next level.

I’ve gone hard on the spice by using dried ancho chilli flakes, hot chipotle chilli paste and a handy tin of kidney beans in chilli sauce, which does all the hard work for you.

After six hours of hands-off cooking, the chunks of beef will literally pull apart and make you wonder why you’ve bothered with beef mince for all those years!

How To Make Slow Cooked Beef Chilli Tacos

Tips & Notes To Know

  • Toast your spices: Raw spices can taste flat or harsh – heat awakens the natural oils and concentrates the flavour. Start with a dry frying pan over a medium heat and shake the pan regularly to prevent scorching. It can take as little as 30 seconds for the spices to darken and release their aromas, so keep a close eye on them.
  • Make it mild or wild: Adjust the amount of chilli flakes or chipotle chilli paste to suit your spice level. A dash of sriracha sauce over the top is my kind of vibe.
  • No beef? Try skinless chicken thighs or go vegetarian with extra beans or tinned lentils. You can also bulk it out with peppers, sweet potato or sweetcorn.
  • Crunchy or soft: Use hard taco shells for a crispy bite or soft tortillas for a messier, more comforting wrap.
  • Double the batch: Leftover chilli can be frozen or piled into nachos, rice bowls or baked potatoes for tomorrow’s lunch.

Frequently Asked Questions

What’s The Difference Between Plum And Canned Chopped Tomatoes?

Canned tomatoes are picked at their ripest and retain more texture than passata because they are less processed. Canned cherry tomatoes are highly prized because of their wonderfully sweet flavour, while whole peeled ‘plum’ tomatoes are generally favoured over chopped tomatoes because they are the most versatile and fuller in flavour.

It is true that you get what you pay for, so try and seek out the best quality tomatoes to produce a richer and more flavourful sauce.

What Is Chipotle Chilli Paste?

Chipotle chilli paste is a spicy blend of dried and smoky chipotle peppers. Most shop-bought jars also contain other ingredients, such as onions, tomato purée, vinegars, garlic and ground spices.

It is a staple in Mexican cooking and is particularly delicious in scrambled eggs and homemade baked beans. I often use it to elevate dishes like chilli con carne, fajitas and enchiladas.
