Sausage And Bean Casserole

OMG it has suddenly got cold, September is here, and I am ready for slow cooker season. I just looked and the last slow cooker recipe I shared was back in April for slow cooker steak and ale pie.

Its shows that I am not a summer person when it comes to the slow cooker, well unless it is slow cooker Mediterranean chicken casserole, and I am all about the comfort food, when the kids have gone back to school and it’s getting colder.

Talking about the kids going back to school and having a delicious sausage casserole with baked beans, Jorge’s favourite food of all time, is baked beans.

He is now back at school on the school dinners, talking about baked beans and how he wish, it was on the menu every single day.

And at home too.

So, we made this delicious sausage and bean casserole, then added two extra cans of baked beans to it just for Jorge.

Then he had it as a family slow cooker dinner, plus reheated the leftover sausage casserole the next day too. Talk about a happy little boy!

If you love comforting slow cooker meals now it’s getting a bit cooler here are some more: slow cooker leek and potato soup, slow cooker braising steak and onions with plenty of mashed potatoes, and my personal favourite slow cooker mince beef cobbler.

Do You Have To Brown Sausages Before Slow Cooking?

Its optional. We all love those beautifully brown sausages in a sausage casserole, but of course, nothing says you have to.

I use my ninja foodi slow cooker function for slow cooker recipes and it has a saute so I tend to brown the sausages just because I can from the same pot. But if you have a slow cooker that has browning option, I will not bother.

Sausages in slow cooker without browning are still delicious they just don’t have that browned look.

Can You Put Frozen Sausages In The Slow Cooker?

No, its not advised to put any kind of frozen meat in the slow cooker and this includes frozen sausages. This is because when you cook sausages from frozen you need the cooking device to be piping hot, in order to kill off the bacteria.

If your sausages are frozen, we recommend that you follow our guide for defrosting sausages in the microwave first.

Money Saving Sausage And Baked Bean Casserole

The wonderful thing about making a sausage and baked bean casserole, is that it is perfect for transforming into a much bigger slow cooker pot of food and feeding your family for more than one day. Or then batching for the freezer and you are creating 2 meals or the effort and cost of 1.

Here are some money saving tips for your slow cooker sausage and beans casserole:

  • Go for the cheap baked beans from the supermarket – compared to Heinz you can make a big saving.
  • Add more baked beans to your slow cooker sausage and beans casserole. Bulking out food with beans can turn it into a much bigger portion size. Especially if you have a bigger family to feed.
  • Add more potatoes and carrots. Just like bulking out your sausage casserole with more baked beans you can do the same with more potatoes and carrots. This casserole is also brilliant for making the night before grocery shopping day when you have spare potatoes that need using up.
  • Once you have cooked your bean and sausage casserole, remove the sausages and chop them into quarters and then stir your casserole. By doing this the sausages can stretch further, and you can feed more mouths. Or if the budget is tight add less sausages. 

What Sausages Are Best For Bean And Sausage Casserole?

Thick sausages such as Cumberland sausages are the best for cooking in the slow cooker. Both for a sausage casserole with beans (like we are making today) and also for other sausage slow cooker recipes. That is because they don’t break very easily because they are much bigger.

I would also avoid sausages that are overly fatty such as the Richmond bags of sausages as they can make your casserole very greasy.

Sausage And Bean Casserole Slow Cooker Ingredients

Sausage And Bean Casserole Slow Cooker Ingredients

Sausages – We were planning leftovers and reheating some of the baked bean and sausage casserole for the next day, so used 8 cumberland pork sausages from the butchers. But if you are feeding less people, you can use less.

Bacon – If you love bacon, then we recommend some bacon rashers and then slicing them into squares and adding them into the slow cooker after the sausages.

Beans – Okay so we planned to add one can of baked beans to the casserole, but Jorge had other ideas and we added three! The amount you use depends on how many you are feeding, as it can make it stretch further and how much you like baked beans!

Tomatoes – We also recommend a can of tinned tomatoes. Any type is fine but chopped tomatoes are easier to mix into your sausage & bean casserole.

Potatoes. Then the potatoes (alongside the baked beans) do a wonderful job of filling you up and we recommend adding some in. You can use any size, and as long as they are no bigger than a roast potato size, then they will cook at the same rate as the sausages.

Veggies – Then for other veggies you can add what you like. We usually add an onion to sauté early on after the browning of the sausages and usually some carrots too. The general rule here is any root vegetables so think swede, turnip, carrots, or parsnips work well.

Extras – We also love some garlic puree, tomato puree, and some seasonings. For seasonings for our sausage bean casserole, we added salt, pepper, mixed herbs, and sweet paprika.

Can You Recommend A Slow Cooker?

I often get asked which slow cooker I recommend and which one I use. In 95% of our slow cooker recipes, we use the Ninja Foodi and its slow cooker setting. Because the Ninja Foodi is an all in one cooking pot we can sauté, air fry, slow cook, and even dehydrate and make yoghurt, all from the same cooking pot. 

Plus, we recommend you head over to our slow cooker recipes category as we have more than 100 tried and tested slow cooker recipes and have been using slow cookers for 18 years. Or more specifically check out all our ninja foodi recipes.

How To Make Sausage And Baked Bean Casserole?

  • Brown. Start by turning your slow cooker on high and browning your sausages until they are brown to your liking. When we brown sausages for a sausage casserole we use the sauté setting as its quicker. You can also skip this step if you are not interested in browning.
  • Sauté. Next put the sausages to one side, then the same again but this time sauté your chopped bacon and peeled and diced onion. You may need some olive oil to stop the bacon and onion from sticking.
  • Dump. Then this is the best part of making a slow cooker sausage and bean casserole, and this dumping everything else in, stirring and then adding the lid. I usually peel and dice the potatoes and carrots whilst the onion is sauteing and then I am ready for adding everything in.
  • Cook. Then slow cook for 4 hours on high or 7 hours on low. Stir in extra beans if required, add ketchup, stir and serve.

And I am sure you can see now how simple and easy this recipe for sausage casserole with baked beans is, and how much your kids are going to love it.

How Long Does Sausage Casserole Take In Slow Cooker?

The sausage casserole slow cooker time is JUST 4 hours on high or 7 hours on low. This is perfect for both a medium and a large batch of slow cooker bean casserole.

How Long To Cook Raw Sausages In Slow Cooker?

Raw sausages in the slow cooker take approximately 3 hours to cook on high. But when they are cooked as part of a meal in the slow cooker such as this sausage casserole with beans, another hour produces the best results.

Can You Reheat Sausage Casserole?

Yes, you can reheat sausage casserole. Though, did you know you can reheat this sausage baked bean casserole in the slow cooker the day after?

What we do is after we have enjoyed our evening meal of sausage and beans, we will place the slow cooker cooking pot into the fridge.

Then the next day about 90 minutes before we plan to eat, we will add the slow cooker pot back to the main slow cooker and cook on high for 90 minutes. This will reheat the sausage and baked bean casserole perfectly and its then ready for dinner number 2.
