Why This Sausage Casserole Is So Budget-Friendly
Sausages are already a handy ingredient because they are full of flavour. You do not need lots of expensive extras to make the meal taste good.
A basic sausage casserole works well because it uses:
- Sausages for flavour and protein
- Potatoes to make it filling
- Beans to stretch the meal further
- Carrots and onions for cheap flavour
- Stock and tomatoes to make a rich sauce
- Frozen veg if you want to bulk it out even more
This is also a great “use what you have” recipe. If you only have baked beans, use those. If you have a tin of chopped tomatoes, throw it in. If you have leftover veg sitting in the fridge, add it before it goes to waste.

How To Make Cheap And Easy Sausage Casserole
Step 1: Brown The Sausages
Heat the oil in a large frying pan, casserole dish, or oven-safe pot.
Add the sausages and cook them until browned on the outside. They do not need to be fully cooked at this stage because they will finish cooking in the casserole.
Browning them first gives the whole dish more flavour, so do not skip this step if you have time.
Remove the sausages and set them aside.
Step 2: Cook The Onion And Carrots
In the same pan, add the sliced onion and chopped carrots.
Cook for around 5 minutes until the onion starts to soften. Add the garlic and cook for another minute.
This helps build the flavour base of the casserole without needing lots of expensive ingredients.
Step 3: Add The Sauce Ingredients
Stir in the tomato puree, chopped tomatoes, stock, herbs, paprika, and a little salt and pepper.
Give everything a good stir and scrape up any browned bits from the bottom of the pan. That is where a lot of the flavour is hiding.
Step 4: Add Potatoes, Beans, And Sausages
Add the chopped potatoes and drained beans, unless using baked beans, then add the whole tin.
Slice the sausages into chunks or leave them whole, depending on how you like them. Slicing them helps stretch the sausages further, especially if you are feeding children or trying to make the meal go a bit further.
Stir everything together.
Step 5: Cook Until Thick And Tender
You can cook this sausage casserole two ways.
Oven Method
Preheat the oven to 180°C / 350°F.
Cover the casserole dish and bake for 35 to 45 minutes, or until the potatoes are soft and the sausages are fully cooked.
Remove the lid for the last 10 minutes if you want the sauce to thicken a little.
Hob Method
Bring the casserole to a gentle simmer.
Cover and cook on low for 35 to 45 minutes, stirring now and then, until the potatoes are tender and the sauce has thickened.
Add a splash more stock if it starts to look too dry.
Slow Cooker Sausage Casserole Method
This recipe also works well in the slow cooker.
Brown the sausages first if you can, then add everything to the slow cooker. Cook on:
- Low for 6 to 7 hours
- High for 3 to 4 hours
If the sauce is too thin at the end, remove the lid for the last 20 to 30 minutes or stir in a little cornflour mixed with cold water.
Easy Ways To Make It Even Cheaper
This is already a low-cost meal, but there are a few ways to make it stretch even further.
Use Fewer Sausages
Instead of using 8 sausages, use 4 to 6 and slice them into chunks. Add extra potatoes, beans, or vegetables to bulk out the dish.
Add Lentils
Red lentils disappear into the sauce and make it thicker. They are cheap, filling, and a great way to stretch a casserole.
Use Frozen Vegetables
Frozen peas, carrots, mixed veg, or sweetcorn are handy because they do not spoil quickly and you only use what you need.
Serve With Bread
A slice of homemade bread or soft dinner rolls turns this into an even more filling meal. These Light And Fluffy Einkorn Dinner Rolls would go really well with sausage casserole:

Storage And Reheating
Let the sausage casserole cool before storing.
Keep leftovers in an airtight container in the fridge for up to 3 days.
Reheat until piping hot all the way through. You can reheat it in a pan on the hob, in the microwave, or in the oven.
You can also freeze sausage casserole for up to 3 months. The potatoes may soften slightly after freezing, but it will still taste good.
For best results, freeze in portion-sized containers so you can pull out an easy dinner when you need one.
Common Mistakes To Avoid
Not Browning The Sausages
You can skip browning if you are in a rush, but the flavour is much better when the sausages are browned first.
Cutting The Potatoes Too Big
Large chunks take longer to cook. Keep them bite-sized so they become soft at the same time as the rest of the casserole.
Adding Too Much Stock
The casserole should be saucy, not watery. Start with the amount in the recipe and only add more if needed.
Forgetting To Season
Sausages can be salty, so do not overdo it at the start. Taste near the end and adjust with salt, pepper, herbs, mustard, or Worcestershire sauce.
Cooking On Too High A Heat
A gentle simmer gives the best result. If the casserole boils too hard, the potatoes can break up and the sauce may reduce too quickly.
Cheap Sausage Casserole Variations

Spicy Sausage Casserole
Add chilli flakes, smoked paprika, or a little hot sauce for extra warmth.
Vegetable-Packed Sausage Casserole

Cheesy Sausage Casserole
