This Slow Cooker Vegan Chilli is the easiest chilli I make: kidney beans, mushrooms, red pepper, onion and garlic go into the pot with chopped tomatoes, cumin, chilli, coriander and a little cinnamon. It takes 5 minutes to prepare, then the slow cooker does the rest. It serves 4, and if you like this, try my Vegan Chili too.


Slow Cooker Vegan Chilli at a Glance
James's tipIf the chilli is thinner than you like, take the lid off for the last 30 minutes on high and mash a few of the beans against the side of the pot. It thickens up nicely.

Why this recipe works
This vegan chilli recipe is perfect when the nights draw in and you want something warming without the fuss. Everything goes into the slow cooker raw, and hours of gentle cooking bring out a deep, rich flavour.
It is on repeat in my house. No slow cooker? You can make it in a pot on the hob in about 40 minutes instead (see the FAQs).
Serve it over rice or quinoa (my How to Cook Quinoa guide makes it easy), spooned over Hasselback Potatoes, or piled onto Easy Slow Cooker Jacket Potatoes. Leftovers make a great lunch the next day.
Ingredients to make Slow Cooker Vegan Chilli

- Mushrooms: Chestnut mushrooms add colour and a meaty bite, but button mushrooms work too. Use any spares in my Vegan Sausage Rolls.
- Red Pepper: Adds colour, sweetness and texture. Any colour of pepper works.
- Kidney Beans: Two tins, drained, for protein and a hearty texture.
- Onion: White or red both work.
- Garlic: Finely chopped, for depth of flavour.
- Chopped Tomatoes: The base of the sauce, with a little water to loosen it.
- Cumin: Warm and earthy.
- Mild Chilli Powder: Gives a gentle heat. Use medium or hot if you like it spicy.
- Ground Coriander: Floral and citrusy, it pairs well with the other spices.
- Cinnamon: My secret ingredient. One teaspoon adds warmth and a subtle sweetness without making it spicy.
- Vegetable Stock: One stock cube or pot adds concentrated flavour. A low salt cube brings the salt down to about 1.4g a portion.
See recipe card for full information on ingredients and quantities.
Substitutions
- Kidney Beans: Swap for black beans, pinto beans or a tin of mixed beans.
- Meat Version: For a chilli con carne, brown 500g of beef mince in a pan first, then add it to the slow cooker with one tin of beans instead of two.
- Vegetables: Swap the peppers or mushrooms for courgette, carrot, sweet potato or sweetcorn. Add soft veg like courgette for the last hour.
Variations
- Spicy: This chilli is mild. For more heat, use medium or hot chilli powder, add a pinch of chilli flakes, or top it with fresh chopped chillies.
- Deluxe: Stir in a teaspoon of cocoa powder or a square of dark chocolate for a richer sauce, and top with chopped coriander and a dollop of coconut yoghurt.
- Kid Friendly: Leave out the chilli powder and add a teaspoon of smoked paprika instead. Kids also love helping to make my Sweet Potato Gnocchi.
How to make Slow Cooker Vegan Chilli

Step 1: Finely dice the onion and garlic and roughly chop the mushrooms and pepper. Drain the kidney beans.

Step 2: Add everything to the slow cooker, stir, pop the lid on and cook on high for 3.5 hours or low for 7 hours. If it is too thin, take the lid off for the last 30 minutes.
For another hearty slow cooker dinner, try my Easy Slow Cooker Sausage Casserole or Slow Cooker Chickpea Curry.
Leftovers
Cool leftovers quickly, keep them in an airtight container in the fridge and eat within 2 days. Reheat once, in a pan or the microwave, until piping hot all the way through. To freeze, portion it into containers and freeze for up to 3 months, then defrost in the fridge overnight. Leftovers are great on an Air Fryer Jacket Potato.
Recipe FAQs
This one is kidney beans, mushrooms, red pepper, onion and garlic in chopped tomatoes with cumin, mild chilli powder, ground coriander and cinnamon. Black beans, pinto beans or lentils all work too.
For me it is cinnamon. A teaspoon adds warmth and a subtle sweetness. A teaspoon of cocoa powder or a square of dark chocolate also makes the sauce richer.
Take the lid off for the last 30 minutes on high so some of the liquid cooks off, and mash a few of the beans against the side of the pot. If it is still thin, stir in 1 tsp cornflour mixed with a splash of cold water. Cornflour thickens without the floury taste plain flour can leave.
Yes. Cool it, portion it into airtight containers and freeze for up to 3 months. Defrost in the fridge overnight, then reheat until piping hot, adding a splash of water if needed.
Make it on the hob. Fry the onion and garlic in a little olive oil in a large pot until soft, add everything else, then simmer gently with the lid half on for about 30 minutes, stirring now and then.
Rice, quinoa or a jacket potato are my favourites. It is also great with tortilla chips, or scooped up with my Gluten Free Flatbread.

Have been looking for a decent vegan chilli recipe for sometime now. This is just perfect, I pop it on before I go to work and have a comforting, warming meal when I’m back. The flavours are delicious and I’m already looking forward to making it again next week.
