Slow Cooker Vegetable Cassoulet – Vegan Bean Stew
A hearty Vegan White Bean Stew, Slow Cooker Vegetable Cassoulet is packed with flavour and topped with a crunchy breadcrumb topping.
Haricot and flageolet beans are slow cooked with butternut squash, veggies, bay, sage and thyme. All served with a crunchy breadcrumb topping.
You can of course serve veggie sausages or meat sausages with the cassoulet if you wish. But for us, we love it just as it comes from the slow cooker pot.

A bean stew here at the Kitchen Shed is always popular. Whilst Guernsey Bean Jar is a firm favourite, I wanted to try an equally tasty meat free version.
What Is A Cassoulet ?
This is my healthy take on the classic French dish. Just like Bean Jar, cassoulet is primarily a casserole or bean stew which includes a relatively small amount of, usually, cheaper meat.
Originating in the south of France, the meat content of contemporary regional recipes includes ham hock, sausage or confit duck.
A typical humble peasant dish, beans form the bulk of these recipes. And because slowly cooked beans absorb flavours of other ingredients, you can make a meat free cassoulet.

My version ditches the meat. Beans themselves are protein heavy, full of fibre and iron. In addition, beans are good for your levels of cholesterol and blood sugars.
I’ve used butternut squash from the Kitchen Shed pantry as last year’s harvest kept really well. I’ve also used a selection of vegetables: parsnips, celery, carrots, onions and leeks.
By way of a change, I decided to use cider instead of wine and found it worked really well. Bay, sage and thyme infused with the cider to then flavour the slow cooked haricot and flageolet beans.
The optional crunchy topping of breadcrumbs tossed in olive oil, garlic and freshly chopped parsley is definitely a worthwhile finish.

The cassoulet itself can be left to cook all day while you go out and about. On your return, you’ll be greeted by a wonderful aroma and an amazing, delicious one pot meal ready to go.
Slow Cooker Vegetable Cassoulet is a really versatile and extremely tasty vegan bean stew for the whole family. It’s so delicious you don’t even notice it’s meat free.
What Ingredients Do I Need ?
For the stew:
Basic vegetables – a couple of onions, garlic and 450 grams of chopped vegetables. Slow Cooker Vegetable Cassoulet is ideal for using leftover vegetables you may have around in your kitchen. I used celery, parsnip, carrots and leeks.
Butternut squash – adds colour and sweetness as well as being full of fibre, potassium and anti-oxidants.
Haricot beans/navy beans – adds a creaminess to the stew. If you don’t have haricots, use cannellini or butter beans instead.
Flageleot beans – typically used in French casseroles. A more delicate flavour because they are young haricot beans. Flageleot beans can be harder to find but substituting them with haricot or cannellini beans works well.
Tomatoes – a can of good quality chopped Italian tomatoes.
Cider or wine – I used a dry cider. If you prefer to cook without alcohol just substitute more vegetable stock.
Vegetable stock – I used Marigold.
Herbs and seasoning – I used fresh sage, bay and thyme.
For the Crunchy Crumb Topping:
You will need fresh breadcrumbs, garlic, fresh parsley and olive oil for the crispy breadcrumb.

How To Make Slow Cooker Vegetable Cassoulet – Vegan Bean Stew
This hearty stew is easy to make with just 15 minutes tops of prep time. After that, you can leave the slow cooker to do all the work for you.

- Soften onions in a little oil in a large frying pan before adding them to the slow cooker.
- Use the same large pan to gently fry the butternut squash, diced vegetables and garlic for about 5 minutes. Once fried, add them to your slow cooker pot.
- Lastly, add the rest of the ingredients to the slow cooker. Leave to cook for four hours on high or eight hours on low.

How To Make The Herb And Garlic Breadcrumb Topping
Toss your breadcrumbs with garlic, parsley and olive oil and then place on a baking tray.
Bake for 10 to 12 minutes. Check halfway through cooking time, moving the breadcrumbs about to prevent burning.

How To Serve
Served with the crunchy garlic and parsley breadcrumb topping your cassoulet is a complete meal.
For a change and a treat, why not try Garlic and Herb Twister Bread ?
Can Slow Cooker Vegetable Cassoulet Be Reheated ?
Yes, Vegan Bean Stew can be made ahead, cooled and stored in the fridge for up to 4 days. Store the breadcrumb topping in a separate container and refrigerate.
Reheat cassoulet in a pan on the stovetop over a medium heat for about 10 minutes, stirring occasionally. It tastes absolutely delicious after being reheated. Pop the breadcrumb topping on a tray and reheat for 10 minutes in the oven.

Can I Freeze It ?
You can freeze Slow Cooker Vegetable Casserole for up to three months in an airtight container. The optional garlic and parsley crunchy topping can be frozen separately.

This looks delicious! Love anything I can cook in the slow cooker! #recipeoftheweek
This sounds really nice, I love that some of the ingredients are home grown we have never had any luck with growing butternut squash, but we are trying again this year! Thank you for joining us at #BloggerClubUK hope to see you again next week xx
Thanks, it’s a pleasure to link up with #BloggerClubUK. Butternut squash are difficult to grow especially in the UK, I think they grow better here in France because it’s a little hotter, there is a variety of seeds you can buy, they’re smaller butternuts but especially for growing in the UK. You could try marina di Chioggia, it’s a squash that’s easier to grow and is delicious, I love it and grow it every year too.
Sounds right up my street! I love a dish you can leave all day to cook then come home to those lovely smells of home cooked food! Yum! Thanks for linking to #CookBlogShare
I love a meatless dish- especially one that can be prepared so easily in the crockpot and is ready to eat upon arriving home from a busy day. Plenty of protein in the beans to make you feel full and satisfied! #bloggerclubuk
This sounds delicious, Sarah. We love a bean casserole and yours with the squash and topped with the breadcrumbs looks wonderful. #cookblogshare

Thanks Angela, squash is one of my favourite veggies & the crunchiness of the topping works well with the softness of the squash x
This looks fab. I’ve been cooking with beans a lot lately, really since my youngest (15 months) started weaning. He struggles with meat and so I’ve been making a lot more vegetarian meals. I love slow cooker meals for ease and I’ve pinned for later 🙂 Thanks
Thanks Amy, my boys used to prefer the texture of beans to meat when they were young. Thanks for pinning, let me know how you get on 🙂
This looks so delicious and warming and there’s so much crammed in I doubt I’d miss the meat. I love the sound of the crunchy topping too. I don’t slow cook things all that often (I don’t have a slow cooker so only do them in the oven) but when I use butternut squash I find it goes too mushy. Do you have any tips for keeping it a bit firmer?
Thanks Charlotte, butternut squash tends to keep its shape more in the slow cooker but you could try adding it halfway through the cooking time instead or you could try cooking the dish in the oven for a couple of hours in a low oven, adding the butternut squash 30 minutes before the end if you prefer a firmer texture.
This looks fabulous. I got a slow cooker in the January sales so am always on the look out for recipes now x #bloggerclubuk
oooh i like the sound of this, perfect winter warmer food x
This sounds delicious and I especially love the sound of those garlicy breadcrumbs with the parsley mixed through. Definitely a great way of finishing this dish off. Thanks so much for joining in with #CookOnceEatTwice.
Thanks Corina & a pleasure to link up with #CookOnceEatTwice 🙂
