Hello autumn! And welcome back bonfires and woolly sweaters and casseroles my old friends.

You know I love a slow cooker recipe, but we can get stuck in a rut with the kinds of meat we’re using (if you’re indeed a meat-eater).

SO I needed to try and make a sausage casserole in the slow cooker!

Mainly because sausages are such a big hit with the whole family, are versatile, inexpensive and ideal for keeping in the freezer.

This Slow Cooker Sausage Casserole is SO GOOD on all counts.

Wholesome beans and a thick, rich tomato sauce. Totally satisfying, hearty and delicious. I hope you love it as much as we do!

How we came up with this recipe

A version of a Slow Cooker Sausage Casserole has been here on the site since 2021.

The original version included fried chorizo, which I love, but this year I really wanted to update the recipe slightly to make it more affordable. (Of course, you could still add chorizo pieces if you wanted.)

So, this recipe uses sausages and vegetables, along with cannellini beans for added nutrients, making a complete meal.

If you’d like a non-slow cooker version, you could try my tasty Sausage Casserole with Cider and Bacon, which cooks in the oven instead.

What to serve with Sausage & Bean Casserole

Rice
Potato wedges
Cous cous – Love this as it’s super speedy.
Add sliced chillis or chilli sauce
Mashed potatoes
Homemade chips

Top tips

Sausages

I like to use sausages with a high meat content (97% if you can get it) without too many other flavourings as there’s already a lot in the sauce. If you use smaller sausages like chipolata sausages, just reduce the cooking time slightly.
