The Low Carb Alternative to Mashed Potato: Cheesy Marrow Mash – Stunningly Simple Low Carb ‘Sides’


The humble marrow feels very much the ugly duckling of the gourd family.  Sometimes its  sheer cumbersome, hulking bulk is enough to put you straight off – it feels as if you’ll be ploughing through the stuff for days, and most cooking methods don’t bring out its best.

But marrow is very much a keto-go-go vegetable! At circa 1.9g net carbs per 100g, it’s super low and is therefore perfect for diabetics, ketogenic dieters or anyone simply wishing to beat the bloat! And add to this, it’s abundant and hugely economical at this time of year – no other vegetable packs as much punch to the pound!

I always think that the best way to prepare marrow is mashed. It has the luxuriant feel of mashed potato, but none of the starch!

Start by cutting your marrow into large chunks (skin on). Remove the seeds with a spoon and place the portions onto a baking tray and drizzle with olive oil. Season well and into a hot oven they go for 40 minutes to an hour, until the flesh is soft and starting to brown at the edges.

Remove from the oven and scrape the flesh into a casserole dish with a soup-spoon. I find this is best done by picking up each piece in turn and holding it with an oven glove. The flesh should come out incredibly easily, leaving the tough skins behind which can simply be discarded.

Add a knob of salted butter to the pan, followed by a generous handful of grated cheese. I also add a good dollop of English mustard for background depth, but that’s entirely up to you.

Check the seasoning and add more if required, then mash out the lumps with a potato masher or fork. Back into the oven it goes for circa 20 minutes, or until the surface is golden brown and bubbly.

Hey presto – our ugly ducking’s a swan!

Thanks for reading and bon ap!

  1. There seems to be a problem on your site. The background is pale grey and the text is white making it basically unreadable. Tried it on both Chrome and Firefox same result


  2. The white text on your website is pretty much unreadable against the light background.. You might wish to think about a darker text or a dark background


  3. I’m sure your website has some great information – but the colour scheme makes it impossible to read!! Light grey background and white text means the words are just about invisible!! Please can you change the the colour scheme – or if you need help with this, just give me a shout as I’m a website designer!


    • Hi Michelle, thanks for the nudge! I think I’ve fixed it now. Haven’t posted anything in a couple of years so hadn’t really looked at it! Time for a new year refresh I think! Thanks again, Adam.
