This super easy sausage casserole recipe not only tastes delightful but it’s healthy and requires very minimal effort. Just like my epic Toad in the Hole recipe, it’s also made using just one pan too! Yep – this is the dream meal right here!

This easy sausage casserole has been made in my house more times than I can count! It’s most definitely a household staple and one that I always find myself recommending to people when they ask me for recipes.

Even when my fussy eating child came along – I just chopped everything a little smaller and even she loved it! It’s the perfect easy, healthy midweek meal meal. 

It’s also cheap to make too, especially if you find great sausages when they’re on offer! You really can’t lose with this recipe.

That being said, if you’d rather go ‘comfort food’ sausage as opposed to healthy – this one pot cajun sausage pasta will be right up your street!

What sausages can you use in a sausage casserole?

Literally any sausages you want! Lincolnshire, Cumberland, chipolata… any sausage you fancy or happen to have in your fridge will work just fine. You can even make it vegan by using vegan sausages instead!

It’s worth noting that these are usually frozen and tend to cook a lot quicker though, so they’re probably best added to the pan right before they go back into the oven for the final 20 minutes. (Not right at the start as per the recipe below.)

Is sausage casserole easy to make?

There are only 2 step by step images in this post. If you’ve used any of my recipes before, you’ll know that this only means one thing – it’s CRAZY easy to make!

Literally all you have to do is chop some veggies and throw them in a roasting pan with some sausages, seasoning and oil. Roast for a little while – then add some tinned tomatoes, stock and herbs. Then roast again for a bit and that’s it! The oven pretty much does all the hard work for you.

One pot sausage casserole recipe tips

Never made a sausage casserole before? Here’s some useful tips to help you get it right!

  • Don’t just dump it all in and hope for the best! Follow my instructions on how to slightly segment the cooking of different ingredients and everything will be fine.
  • Want to use different types of peppers/onions than what’s stated in the recipe? You absolutely can! Don’t be afraid to mix things up a little or use up what you have in the cupboards.
  • Want to add some extra depth of flavour? Add 1 tbsp of balsamic vinegar in along with the tomatoes and you won’t regret it.
  • Use a good non stick pan.
  • Cooking for fussy eaters? Chop the veg smaller or even keep as per the recipe then blitz in a processor after for a smooth ‘bits free’ sauce.

After the 20 minutes is up, the vegetables should have softened and it should all have a nice colour to it.

So, remove the tray from the oven and add the tomatoes (400g | 14 oz tin), stock (130 ml | 1/2 Cup + 1 tbsp), basil (a few leaves) and a little more salt and pepper to taste.

Mix well and return to the oven for a further 20 minutes until the sausages are cooked through and the sauce has thickened a little.

Hey, probably a stupid question but I have never cooked sausage casserole before lol is it able to be frozen once cooked and completely cooled? How long safely for please? X

Emma

Thursday 23rd of June 2022

Hi Chloe, not stupid at all! The beans might end up a little mushy but you can absolutely cook, cool completely, then wrap well and freeze for another day. I wouldn’t freeze for longer than 3 months and make sure you fully defrost before reheating. Emma x
