The whole family will love this sausage casserole! Packed with veggies and so easy to prepare, this will be one of your favourite slow cooker sausage recipes and you’ll want it on your weekly menu.
Now autumn is here I love to be able to use the slow cooker to make my family warming and nutritious slow cooked meals, packed with vegetables.
I may occasionally wax lyrical about the convenience of throwing your ingredients in the pot in the morning and coming back after a day at work (or play) to a cooked meal. You just can’t beat it!
This sausage casserole recipe is the perfect way to use up any vegetables lurking in the bottom of the fridge too. If you don’t have a slow cooker you could also make it in a casserole dish/Dutch oven too.
Adapting the recipe
I make the basic recipe quite often for my family, as it is one of the children’s favourites, adapting it to whatever vegetables I have on hand, and sometimes adding a tin of cannellini beans or a handful of red lentils.
You can add beans of your choice to make it a sausage and bean casserole.
Another option is to add potatoes – make sure you cut them small and put them at the bottom of the pot, to make sure they cook through.
We tend to serve it with pasta or rice as my two aren’t big fans of mash. It always goes down well and warms us up on a damp chilly day.
We love the rich tomato-based gravy that you get after the long slow cook. Dipping a bit of bread in there to soak it all up when your plate is clear is one of the best bits!
And using up all those veggies in this comforting and warming dish is just ideal. It is great to come home to a dish like this which has been left cooking all day while you are out, especially in colder weather.
Step by step instructions
- Brown the sausages in a pan.
2. Chop the vegetables and place them in the slow cooker pot.
3. Add the tomato puree, tinned tomatoes, stock, herbs and mix gently.
4. Place the browned sausages on top, then put on the lid and cook on high for 4-5 hours or on low for 7-8 hours.
5. Thicken with cornflour if needed, an hour from the end of cooking. When ready, serve with mash or pasta for a warming autumn or winter dish. Green vegetables work really well on the side.
The sauce is full of flavour and ideal for dipping bread into!

Sausage casserole goes well with mashed potato, pasta or rice, or I also like it with new potatoes or on top of a jacket potato as well.
Green vegetables like broccoli or peas, those family favourites, are a good match.
You can freeze this recipe.
To reheat, defrost well then reheat to piping hot in a saucepan or microwave. Never reheat in the slow cooker (after defrosting) as it does not get hot enough quickly enough. Also never reheat from frozen in the slow cooker.
Do I need to brown the sausages first?
The dish looks better when you brown the sausages in a pan first, otherwise they look very anaemic and not appetising. It also adds flavour. If you don’t mind about that you can skip the browning stage.
Can I use frozen sausages in the slow cooker?
I recommend not using frozen meat of any kind in the slow cooker. If you have frozen sausages, defrost them fully first.
Can I cook this in a casserole dish instead?
If you don’t have a slow cooker the recipe can be made in the same way in a casserole dish. Brown the sausages, fry the onions too if desired, add the ingredients in the same way.
Add 200 ml additional water (since the water will evaporate). Simmer for 45 minutes on medium heat.
How long does it take to cook sausages in the slow cooker?
The basic cooking times for a slow cooker are 8 hours on low or 4-5 hours on high. The same applies for this recipe.
