This Slow Cooker Sausage Casserole is the ultimate comfort food. Its warming, filling, and packed with goodness. Let your slow cooker do the work and enjoy a family friendly meal everyone will look forward to.
I've loved my slow cooker since my boys were babies. In the early years it was a lifesaver when the evening routine felt overwhelming.
Now with busy after school schedules and sports, it's still just as valuable for easy family dinners like this Slow Cooker Sausage Casserole, along with favourites such as Slow Cooker Chicken Curry, Slow Cooker Curried Sausages, Slow Cooker Beef Stew, Slow Cooker Chicken Noodle Soup, and Slow Cooker Shredded Chicken.

Reasons to Love this Recipe...
- Easier Evenings - Prep in the morning for a fuss free dinner ready when you are.
- Family Friendly - Most kids love sausages, making this a crowd pleaser for busy weeknights.
- Veggie Packed - A more nutritious way to serve sausages, with a variety of vegetables and beans for extra fibre and goodness
- Tried and Tested - Cooked many times at HLF headquarters and enjoyed by many readers.
Ingredient Information (With Alternative Suggestions)
- Sausages - Choose good quality with at least 85% meat content, lower sodium, and <4g saturated fat per 100g.
- White Beans - I use cannellini beans (also callled white kidney beans). You can also use navy or butter beans if preferred.
- Vegetables - Onion, garlic, celery form the flavour base. I also add carrot and capsicum (pepper), but you could mix in extras like peas or spinach (stir in the last 15 mins of cooking).
- Canned Tomatoes - Form the rich sauce base, chopped or crushed both work.
- Tomato Paste - Adds extra depth and richness.
- Smoked Paprika - Brings a gentle smoky flavour.
- Chicken Stock Cube - Optional, you can skip it to lower salt levels, especially for young children.
Step By Step Instructions (With Images)
- Brown Sausages in pan (or use your slow cooker if it has a sauté function)
- Soften Aromatics: Cook the onion, celery, and garlic until softened.
- Load the Slowcooker: Add sausages, carrot, pepper, beans, tomatoes, tomato paste, paprika, and stock cube. Stir well.
- Cook: Cover with the lid and cook on low or high. Sprinkle with fresh parsley (optional).
Top Tips
- Don't skip browning the sausages. It improves flavour, makes them visually more appealing, and helps release excess fat so the casserole isn't too greasy.
- Onion and celery can go in raw but sautéing them first add sweetness and depth.
Serving Suggestions
- Mashed potato - Great for soaking up the rich tomato sauce.
- New potatoes or jacket potatoes
- Potato wedges
- Crusty bread
- Rice or pasta
- Green veggies
Storage Instructions
- Refrigerate: Cool the hotpot quickly; store in an airtight container and refrigerate for up to 2 days.
- Freeze: Cool the hotpot quickly, transfer to an airtight container and freeze for up to 3 months.
- Thaw, overnight, in a refrigerator and reheat on the stove top or microwave until piping hot throughout.
Recipe FAQs
Sausages aren't recommended for babies under 12 months due to their high sodium and fat content. An occasional small taste from 6 months onwards (once baby is established on solids) can be fine as part of a balance diet, but they should not be offered regularly.
The sauce (with vegetables and beans) is more suitable, but I recommend skipping the stock cube to reduce sodium levels. Make sure all vegetables, especially carrots, are cooked until very soft and served in an age appropriate size for your child.
For under twos, cut sausages into strips rather than rounds to lower the risk of choking.
Always check the ingredient list on sausages, as some may contain allergens such as wheat, milk or honey.

We loved this! Really easy and quick to make. We swapped the normal sausages for “This isn’t pork sausages” vegan sausages! Was lovely and put a bit of vegan cheese on top after. Served my toddlers with some sweet potato mash. X
Amy
Sounds perfect! Glad you enjoyed it and could make it work for your dietary needs 🙂

Hi Amy
Love your recipes for my toddler, thanks for sharing! I was wondering what sausages you used for the casserole? I’m in Perth, Western Australia so will have similar brands to you. Being Irish, I also like pork sausages as that’s what we mostly would have back home!
Thanks Amy
Claire
