Like most Brits I’m a big fan of roast potatoes! I’ve got quite a few different recipes on here now, including Ninja Foodi roast potatoes and I have some more in the works too! These Marmite roast potatoes are my new favourite and my whole family love them too.

These work great with a roast dinner but also as a side dish to just about any tasty meal. We love to serve these alongside a slow cooker whole chicken and air fryer pigs in blankets in particular, as this is extra tasty, and I often make onion gravy to accompany this too.

I love crispy roast potatoes, and don’t want them to be greasy. These potatoes are soft and fluffy inside and crispy on the outside. I love to cook them in the Ninja Foodi but you can adapt my methods for the oven (see below fore more details).

This particular recipe was originally cooked in the *OP500UK, which has now been replaced with the *OL550UK but as long as your Ninja Foodi has the air crisp/air fryer and pressure cooker options you’ll be able to recreate this recipe at home in under 30 minutes. I’ve also made it in the OL750UK more recently with the same results too.

If you don’t have a Ninja Foodi, or the right model for this particularly recipe, then be sure to check out my air fryer potatoes or OXO roast potatoes instead! They’re super simple and don’t require pressure cooking, although personally I don’t think they’re a patch on these roast potatoes which are full of delicious crisp edges and super fluffy inside! You can adapt these to be Marmite roast potatoes using the measurements below too.

Ingredients for Marmite roast potatoes:

250ml water

600g potatoes

1 teaspoon Marmite

1/2 teaspoon vegetable oil

1/2 teaspoon of water

How to make Marmite roasties:

Peel, wash and chop the potatoes.

Add to the Ninja Foodi pressure cooker bowl.

Add 250ml of water (minimum!)

Pressure cook for 3 minutes. Use the quick release setting too.

Drain your potatoes, discard the water.

Shake the drained potatoes in the pressure cooker pot. This will rough up the edges a little.

Transfer the potatoes to the air fryer basket.

Cook on 190C for 10 minutes on the air fryer / air crisp setting.

Mix together the marmite and oil. Use 1/2 teaspoon of water to loosen slightly if you feel it is needed.

Pour over the mixture and then mix well.

Cook at 200C for 6-8 minutes. Shake after 3-4 minutes to avoid the potatoes sticking to the air fryer basket.

Depending on the size of your potato you may need a few more minutes. Exercise your common sense here – if they’re not crispy then they’re not fully cooked!

I find that 18 minutes is perfect for the size of potato that I like to serve to my family. We tend to get medium potatoes, but if you’ve got large ones just cut them up into smaller pieces.

Best potatoes for Marmite roast potatoes?

I believe that Maris Piper are the absolute best potatoes to turn into roast potatoes, just from my own experience.Russet potatoes are another favourite of mine, but they’re not always readily available in the supermarket here in the UK where I shop.

Can you cook these from frozen?

You can! Personally I would pressure cook them, drain the potatoes, fluff them up lightly and then air fry / air crisp for 5 minutes. After this I’ve freeze flat on a tray for an hour or two and then pop in to a freezable container!

Add the Marmite mix, then cook these from frozen for around 20 minutes at the same temperature as stated in the recipe here. Shake the air fryer basket at least once during the cooking process.

Preparing in advance and freezing is a great way to save a little of the time/effort/washing up on a Sunday in particular, which is ideal if you’re having guests! I love to make a variety of foods that we can enjoy when I’m short on time, and these potatoes are always a winner.

Want to make this recipe with baby potatoes?

Reduce the cooking time if you wish to do this. I would pressure cook for just 1 minute, quick release and then air fryer for a minimum of 10 minutes in the air fryer. Halfway through I’d add the marmite mixture and then just keep an eye on the potatoes to ensure that they are crispy before serving.

What herbs work well with Marmite roast potatoes?

I find thyme works well. I love to wash the stalks and then rip off all the leaves. I’ll add these at the same time as adding the Marmite mixture, just to save on time and effort.

Want to make these in the oven instead?

I’d suggest parboiling for around 7-8 minutes in boiling salted water. Fluff up, then place into the oven, on a roasting tray, for around 20 minutes at gas mark 6 (200C / 390F), add the Marmite drizzle and then repeat for at least 20 more minutes.

Is this recipe suitable for Vegans?

Yes! Marmite is suitable for Vegans, and as long as you pay attention to the vegetable oil you’re using there is no reason why this can’t be perfect for Vegans! It would go great alongside a Nut roast or similar too.

Do marmite roast potatoes taste like marmite?

A little! The taste is not overpowering like pure Marmite can be, and my daughter who doesn’t like Marmite on toast happily eats these with no complaints!
