Slow Cooker Sausage Casserole

Updated: Dec 10, 2023 by Jenny · 2 Comments

Jump to Recipe

This easy Slow Cooker Sausage Casserole is just delicious. What's more it can be waiting at home for you all day just getting more and more fabulous darling. I also cook it in a regular saucepan if it suits.

It is reliable, warming, easy and delicious. What more could a hassled girl ask for?

The small amount of butter in the tomato and onion sauce gives it yet another level of classic flavour and a good grind of black pepper and splosh of worcestershire sauce bring a warmth that goes perfectly with the meaty sausages. Comfort food baby.

 Sausage Casserole Recipe

I cook it on Low for 7-8 hours or High for 4. You too can come home to this meaty hug in a pot. Seriously delicious winter comfort food.

Ingredients

The preparation is another Brucey Bonus. It is simplicity itself with only a few ingredients alongside some from your store cupboard.

  • 8 meaty sausages
  • 500 mls tomato passata
  • 1 medium onion
  • 2 tbsp tomato ketchup
  • 1 large rosemary sprig
  • 1 large garlic clove
  • 1 tbsp sugar
  • 30 grams butter (optional)
  • 1 tbsp balsamic vinegar
  • 1 tbsp worcestershire sauce
  • 2 tbsp olive oil
  • seasoning

Method

Brown the sausages over a high heat in a frying pan. You are not wanting to cook them all the way through just get some colour on the sides. Add them to the pot.

Add all the ingredients apart from the sausages into the slow cooker pot and flick the switch to high.

Cook on High for 4 hours or Low for 6-8 hours. Simples.

To make this recipe in a saucepan simply repeat the steps above but brown the sausages in a saucepan and simmer for about 15 minutes until the sausages are cooked and the sauce is slightly thickened.

Serving Suggestions

I almost always like to serve this with buttered fresh egg tagliatelle and green vegetables such as tender stem broccoli.

I buy the tagliatelli from the Supermarket and simply put a tbsp of butter through the pasta after I have drained it. I usually have the packets stashed in the freezer so I pull out a packet in the morning that I plan to make the Sausage Casserole.

It is usually 100 grams fresh pasta per adult. I have two young children so use 300 grams for our family of 4.

Other great ways to serve this is with easy cheesy mash or mashed potatoes , roasted new potatoes or even plain old roast potatoes.

Brown or white rice is another good option. It is usually 60-90 grams of dried rice per person. Remember that brown rice takes significantly longer to cook than white. Follow the packet instructions but it is at least 30 minutes.

A jacket potato or  is of course another great choice or ½ a tin of cannellini beans directly in the pot at the beginning of cooking.

Buttery Braised Red Cabbage, slow cooker corn on the cob , roasted broccoli or roasted carrots goes fantastically well too.

One important note to mention is that bread and butter served alongside this is a fantastic way to mop up the sauce. Serious Lushness......

Expert Tips

  • You can of course add extra vegetables. I am thinking chunks of butternut squash or swede, button mushrooms (put in a couple of hours before the end of cooking) or carrots. The vegetable aisle is your oyster. This is just my own personal preference but it is only a template. Empty out your vegetable drawer baby to suit.
  • The herbs too can be replaced to suit your tastes. Thyme is an obvious one to add due to it's great compatibility with pork but you could crush some fennel seeds in there or add some basil or oregano. Jamie would be proud.
  • I sometimes make this the day before, allow to cool and then refrigerate in the slow cooker pot. I then reheat it back in the slow cooker until it's piping hot for when I need it. I'm on fire.....
  • If you don't have balsamic vinegar in the cupboard then any standard vinegar will do.
  • Simply double up to feed 8. These servings are generous.
  • I do strongly recommend that you use sausages with a high percentage of meat in. This gives the whole thing a much better flavour and the sausages stay meaty and intact during cooking.
