- It’s great if you are on a low-carb diet and looking for new flavours on your meal plan.
- The slightly sweet flavour makes it perfect for kids. It’s also fantastic for younger and weaning children.

You’ll Also Need
As well as the ingredients you’ll need:
- Potato peeler
- Sharp knife
- Chopping board
- Large saucepan

How to Make Carrot and Swede Mash – Step-by-Step Instructions
Swede and carrot mash is super simple, like most classic sides.
Full, easy-to-follow instructions and quantities are available in the recipe card at the bottom of this post.
Step One
Peel and chop the swede. I actually think this is the hardest part.
I find that chopping the top and bottom off the swede and then cutting it into four makes it easier to peel.
Then dice it into 1-2 cm chunks.
Peel and slice the same weight of carrots.
Step Two
Place the carrot and swede in a large saucepan and cover with water. Add a pinch of salt.

Step Three
Place the pan on the hob over medium heat and bring to a simmer. Reduce the heat if necessary.
Step Four
Simmer for 20-30 minutes until the swede is soft.
Stab a chunk with a knife to check. I tend to take a bit out with a fork and eat it, after a good cooling blow!
Step Five
Drain thoroughly and return to the pan.

Step Six
Return the pan to the hob over a very low heat. Toss thoroughly for 2-3 minutes to cook off any water.
Step Seven
Return the veg to the colander and set to one side.
Step Eight
Add the butter to the same, now empty, pan and add a pinch of salt and pepper and a small splash of milk (you can always add more later if needed). Melt the butter over low heat, stirring often.

Step Nine
Remove from the heat and tip the swede and carrots into the pan with the melted butter.
Step Ten
Mash thoroughly or whizz with a stick blender until smooth, adding a little more milk if needed.
Serve straight away.

What to Serve with Carrot and Swede Mash
As a Side
Mashed carrot and swede makes a fantastic side dish with things like a Sunday roast dinner, or something simpler like sausages or pork chops.
It can be a healthy alternative to mashed potatoes but can also be served with potatoes. We’ll often have roast potatoes and carrot swede mash with our roast.
Carrot and Swede Mash Potato Topping
Another option is using it as a topping for things like cottage pie. This is an easy way to make your favourite comfort food a little healthier.
If I’m using it as a topping, I’ll often add less butter, so it’s thicker and chunkier.
Variations
Vegan Carrot and Swede Mash
If you want a vegan carrot and sweet mash, swap the butter for either olive oil or a vegan spread. You might need a little less, as these are liquid-based.

Add Thyme
A teaspoon of ground thyme or fresh, chopped time is a great addition, and thyme works really well with swede.
Add Spices to Mashed Carrot and Swede
A little ground nutmeg is a popular addition to swede carrot mash. Other spices like paprika can be lovely, too. Just add a little at a time and taste before adding more.
Carrot and Swede Mash with Garlic Butter
Add a crushed clove of garlic or 1/2 teaspoon of garlic puree to the butter when you melt it for a garlic butter.
Another option is to add a teaspoon of dark brown sugar, which can really highlight the mash’s sweetness.

Leftovers
Leftover carrot and swede mash can be reheated in the microwave for a few minutes or in a pan over medium heat.
If you are reheating in a pan, stir often, and add a splash of milk if it’s too thick.
Another option is using the air fryer. If your machine has a reheat setting, use this and stir every now and then to stop the top from crisping. If not, warm at 150 degrees C. How long it takes will depend on how much mash you’ve got, so start at 5 minutes.
Storage
Store leftovers in a covered bowl or tub in the fridge for up to three days.
Does Carrot and Swede Mash Freeze Well?
You can freeze carrots and swede mash. Keep in an airtight tub and freeze for up to two months.
Thaw in the fridge before reheating.
