One Pot Marmite Mac and Cheese - a rich macaroni cheese with that unmistakable savoury Marmite flavour running through every bite. If you already love Marmite on toast or melted into cheese on toast, this comforting pasta dish is probably going to be right up your street.

Marmite definitely falls into the love it or hate it category, but paired with a buttery cheesy sauce it adds such a delicious deep savoury flavour that works perfectly with pasta. This version is easy to make all in one pot and is perfect when you want a cosy comfort food dinner with something a little different.

Ingredients Notes
To make this recipe you will need the following ingredients:
- Macaroni Pasta: Classic macaroni is perfect for this recipe as all those little tubes hold onto the creamy cheesy sauce really well.
- Butter: Adds richness and helps create a silky smooth sauce.
- Marmite: The star ingredient that gives the dish its deep savoury flavour. You can adjust the amount depending on how strong you like the Marmite flavour.
- Boiling Hot Water: Used to cook the pasta directly in the pan, helping create that creamy one pot sauce.
- 2% Milk: Adds creaminess without making the dish too heavy.
- Strong Cheddar: A good strong mature cheddar works best here as it pairs perfectly with the Marmite flavour and gives a rich cheesy sauce.
- Egg: Helps make the sauce extra creamy and silky once stirred through at the end.
- Salt and Pepper: Season to taste, although you may not need too much salt as the Marmite and cheddar already add plenty of savoury flavour.
Once you've gathered all the ingredients and prepared them accordingly, you're all set to create this easy and delightful recipe.
