Slow Cooker Brussels Sprouts Ingredients

A full ingredients list, along with US Customary and Metric measurements, can be found in the recipe card at the end of this post.
- Brussels sprouts - Make sure to choose fresh Brussels sprouts, as this will make all the difference to the finished dish. There are more tips on how to choose them below.
- Butter and oil - These not only add flavour, but they help with give them a little crispiness on the outside. We used unsalted butter and olive oil.
- Salt and pepper - Sea salt and cracked black pepper are the perfect seasoning.
- Parmesan cheese - This makes the perfect topping to the slow cooker Brussels sprouts. You could use shredded mozzarella if you prefer, but it doesn't have the same flavour.
More ingredient substitutions and variations can be found in the recipe card.
How to Make Slow Cooker Brussel Sprouts

- One: Put all the ingredients in the slow cooker, mix well and cook on high for 2 hours or low for 4 hours.
How to Choose Brussels Sprouts
They key to delicious tasting Brussels sprouts is choosing the best ones. So, here are some of our top tips for choosing them at the supermarket.
You want to look for bright green heads that are firm to touch and heavy for their size. The leaves should be tightly packed too.
Avoid Brussels sprouts that have yellowing leaves (this is a sign of old sprouts) or black spots, which could indicate fungus.
Smaller Brussels sprouts are usually sweeter and more tender than larger ones, so choose those if you don't like any bitterness.
Serving Suggestions
These are a must with any roast dinner. So, here are some of our favourite roast meats and easy side dishes for you to try:

Slow Cooker Brussels Sprouts Storage
Store: If you have leftover Brussels sprouts, then once they have come to room temperature they can be put into an airtight container and stored in the refrigerator for for 3 days.
Reheat: To reheat them, transfer them to an ovenproof dish in a single layer and put them in a preheated oven at 200°C/180°C(fan)/400°F/Gas 6 until they are warm. You could also heat some oil in a frying pan and fry them to reheat. Leftovers are really good in pasta too.
Make in advance: You can chop all of the Brussels sprouts and put them in the slow cooker and keep in the fridge. When you are ready to cook them, let the slow cooker come room temperature, and then carry on with the rest of the recipe. I do this on Christmas eve.
Dannii's Top Tips
- Add some extra flavour by cooking some fresh cranberries at the same time as the sprouts.
- If you want to make these slow cooker Brussels sprouts more indulgent, then why not fry up some chopped up bacon and add it to the slow cooker? A bit like what we do with our slow cooker green beans recipe.
- Add a touch of sweetness - drizzle them with some balsamic glaze before serving. You can also cook them with a little balsamic vinegar.
- Some chopped shallots would also be a nice addition.
- A sprinkle of pine nuts before serving adds some nice texture.
- If you want really crispy sprouts, but with the ease of cooking them in the slow cooker, after cooking you can transfer them to a heatproof dish and put them under the grill for 3-4 minutes.

Frequently Asked Questions
No, there is not need to cut them in half. Just throw them into the slow cooker whole. You just need to cut the stem off.
Yes, if you don't have any fresh or you just want to save yourself some time then you can use frozen. With frozen they are already trimmed and cleaned, so there is no prep at all. They are also really budget friendly and it means you can make this out of season.

Claudia Lamascolo says
One of all time favorite vegetable is cabbage but brussels are so much easier and we make them often I have never even known they could be done in a slow cooker this is awesome!
Emmeline says
If you add parmesan you can get me to love anything, even brussels sprouts! Delicious!
Megan says
Made these for Thanksgiving. I didn't have the option of roasting and serving right away, so needed anothlutio. These were perfect. Delicious without having to take up stove or oven space. I didn’t add parmesan as I don't eat dairy. They were still yummy and I imagine parmesqn would have elevated it.
Dannii says
So glad you enjoyed them. Hope you had a great thanksgiving.
Katherine says

Looks so delicious! The secret with making brussels actually delicious is what you add to them, and this looks like a solid recipe!

Such a lifesaver to not have to take up stove top or oven space to make these. That space is so limited during the holidays. Plus, this makes it an easy to take dish for potlucks in the future. Thanks!

I have never made brussels sprouts in the slow cooker before. This is life-changing!
