Slimming World Marmite Roast Potatoes

Just like my Oxo roast potatoes, these marmite roast potatoes are a popular slimming world recipe. It’s a great way to enjoy a Sunday roast without worrying about calories.

The marmite flavour isn’t overpowering, that’s why it’s a big hit with both marmite lovers and marmite haters.

Recipe Ingredients

Below are the few ingredients needed for this recipe:

Potatoes: I used maris piper potatoes. I’ve listed the best potatoes for roasting below.
Marmite: You can use the brand Marmite or non-branded yeast extracts.
Oil: Use oils suitable for roasting like vegetable oil or sunflower oil. For ‘Slimming World’ friendly marmite potatoes, you can use low calorie oil sprays.
Salt: For extra flavour, I like to add salt to the water when parboiling the potatoes. However, this is optional.

What Are The Best Potatoes For Roasting

Potatoes like king edwards, maris pipers and russet potatoes are great for roasting. These potatoes are quite floury, when roasted they have a fluffy interior with crispy edges; this texture is perfect for roast potatoes.

How To Make Marmite Roast Potatoes

Below is a step-by-step guide on how to make marmite roast potatoes. Full recipe instructions are on the recipe card.

Step One:

Preheat your oven to 200°C (gas mark 6, 180°Fan) and peel and chop the potatoes into quarters.

Bring a pot of water to the boil and add salt. Add the potatoes to the pot and parboil for 10 minutes.

If you’re potatoes are medium to small in size, cut the potatoes into halves instead of quarters. For really small potatoes, parboil for only 5 minutes.

Step Two:

Whilst the potatoes are boiling, add oil and a tablespoon of marmite into your roasting tray and place in the oven.

Step Three:

Drain the water from the pot. Place the lid on the pot and shake the potatoes. This will rough up the edges and create really crispy potatoes.

Step Four:

Carefully take the roasting tray out of the oven and mix the marmite and oil together. Pour the potatoes into the tray and mix it into the marmite and oil mixture.

Step Five:

Bake in the oven for 40 minutes or until crispy on the outside and fluffy in the middle. Turn the potatoes over halfway.

How To Serve

These roast potatoes are the perfect side dish, they’re great for Christmas, Easter and for your Sunday roast. Serve it with this honey glazed gammon or with these delicious recipes below:

My Top Tips

Don’t skip parboiling the potatoes, it partially pre-cooks it. This creates a crispy shell whilst the inside is nice and fluffy. Plus, parboiling quickens the overall roasting time, without this step the potatoes will take longer to roast.

For crispy edges, shake the potatoes whilst in the pot. The roughed-up edges will turn crispy whilst roasting in the oven. For the ultimate crispy texture, allow the parboiled potatoes to steam out for 10 minutes. This will help the potatoes dry out a little bit before roasting.

For a strong marmite flavour, brush extra marmite over the potatoes halfway into the cooking time.

Is Marmite Roast Potatoes Vegan?

These marmite roast potatoes are naturally vegan so more people can enjoy these delicious roasties! Currently, the entire marmite range is vegan, so there’s no animal products in this recipe.

Can I Add Herbs?

Yes, of course you can! I like using herbs like rosemary, thyme and sage when roasting potatoes. Though, you can use any herb you like – they can be fresh or dry!

If you’re using fresh herbs, give them a quick rinse and dry before adding to the roasting tray. You can add sprigs of herbs or rip them into smaller pieces.

How To Store & Cook From Frozen

To store, keep in an airtight container and store in the fridge for up to 2 days. If you want to keep it for longer you can freeze it.

To freeze, allow the potatoes to cool down and place into a freezer-safe container. Store in the freezer for up to 3 months. When you’re ready to eat it, simply cook the potatoes from frozen until hot throughout.
