This easy one pot mac and cheese is loaded with spicy paste(‘nduja or gochujang) to make a supercharged, gooey, saucy mac and cheese with no need to make a roux, no butter and no flour. Just add everything into a pot and let the magical pasta starch do all the heavy lifting.

This technique for mac and cheese is truly a game-changer. Usually, you need to make a cheesy bechamel sauce, cook the pasta separately, and then add everything together. This way, all you have to do is add everything into one pot and stir. 20 minutes max, and you’re done.
The secret? Starch. As the pasta cooks, the starch releases into the cooking liquid, naturally thickening the sauce without having to add anything else. Starch is why you should always add a little pasta cooking water to your finished pasta dishes to thicken the sauce up and make it nice and glossy. And we’re using it to its full potential here. It also means fewer dishes which is always a win in my mind!
‘Nduja paste is the magic ingredient that takes this mac and cheese to another level. This funky, umami-packed spreadable salami from Calabria just delivers so much flavor. It’s spicy, meaty and truly delicious. I also LOVE using gochujang paste here – either works beautifully.
Ingredients
- Pasta. I’m using cavatelli, but you can use any small shape like fusilli or macaroni.
- Milk. You’ll ideally want to use whole milk for the ultra-creamy factor, but semi-skimmed will also work.
- Cheese. I’m using a mix of strong cheddar, gruyere and parmesan. You can mix this up – I’d recommend good strong-flavoured cheeses just so you can really taste them. Adding in a little blue cheese is also lovely.
- ‘Nduja paste. This is the real magical ingredient. ‘Nduja is a spicy, spreadable salami from Calabria in Italy and is a flavor powerhouse. It’s becoming much more readily available – larger grocery stores are starting to stock it, or you can pick it up from Italian delis, or even Amazon. It will either come in a jar on the shelf, or as a slab in the fridge section. If you can’t find it, use gochujang paste, harissa paste, sriracha or finely chopped chorizo.
- Parsley and lemon. We’re going to make a quick, herby zesty gremolata (parsley, lemon zest and garlic) to top the mac and cheese with. This is a wonderful way to cut through the richness of the pasta, so I really recommend making it. You could swap out the parsley for cilantro, scallions or basil if you like.
How to make it
Add a little olive oil and the ‘nduja paste (or gochujang paste) into a large, high-sided pan over medium heat and cook for a couple of minutes until the ‘nduja melts into the oil. At this point, add the pasta, crushed garlic, milk and water. Give everything a good stir, then bring to a simmer. Lower the heat, then simmer for about 10 minutes, stirring occasionally, until the sauce has thickened a bit (it will still be a bit saucy – the cheese will help thicken it more) and the pasta is al dente.
PRO TIP: You can also add the ‘nduja paste at the end when you melt in the cheese – I’ve tested both ways and the result is the same.
While the mac and cheese is simmering, make the gremolata. That’s as simple as mixing the chopped flat-leaf parsley with the zest of a lemon and crushed garlic clove.
Once the pasta is al dente (cooked, but still with a little bite to it), add the cheese and mix to combine it into the sauce. It’ll melt in and smell gorgeous. Remove from the heat, top with the gremolata and serve right away, while hot, gooey and ultra cheesy.
PRO TIP: If you’re using an ovenproof skillet, you can pop the mac and cheese under the grill (broiler) for a few minutes before serving if you like. If you do this, keep about 1/4 cup of cheese aside to scatter on top before you put the pan under the grill. Top with the gremolata once it’s out of the oven.
Got a question?
You can – but be aware that the pasta will continue to absorb the liquid as it sits. It keeps well for five days in the fridge in an airtight container. When you come to reheat it, add a little water (a couple of tablespoons) just to help the sauce loosen up again. You can either reheat on the stovetop for a couple of minutes over medium heat or in the microwave at 1-minute intervals. Store the gremolata separately, then top once the mac and cheese is reheated.
You can replace the ‘nduja with harissa paste or gochujang paste for a vegetarian version. Make sure to taste them first as the harissa can vary widely in spice levels). You may need to reduce the quantity if you use harissa – start with 2 tablespoons). You could also use sriracha, or use finely chopped chorizo or another spicy sausage.
‘Nduja (or gochujang) is a spicy ingredient, so this pasta is spicy. It’s not SUPER spicy, but it definitely has some heat. If you’re worried, reduce the quantity by one tablespoon.
You want something strongly flavored that melts well. This recipe uses a mix of cheddar, gruyere and parmesan, but you can play around based on what you have and what you like. Havarti, Gouda, fontina, Monterey jack, camembert or brie (without their rinds) or creamy blue cheese all work well too.
I like to use whole milk for maximum creaminess, but low-fat milk works really well too!

PrintEasy One Pot Spicy Mac and Cheese
- Total Time: 20 minutes
- Yield: 4 servings
- Diet: Low Salt
Description
This easy one pot mac and cheese is loaded with spicy ‘nduja paste to make a supercharged, gooey, saucy mac and cheese with no need to make a roux, no butter and no flour. Just add everything into a pot and let the magical pasta starch do all the heavy lifting.
Ingredients
For the mac and cheese –
- 1 tablespoon olive oil
- 4 tablespoons โnduja paste (or use gochujang paste)
- 10.5oz/300g dried pasta (cavatelli, fusilli, penne or macaroni are great)
- 2 1/2 cups whole milk
- 1 cup hot chicken stock (or vegetable stock)
- 2 garlic cloves, crushed
- 1 teaspoon salt
- 1 cup mature cheddar cheese, grated
- 1/2 cup gruyere cheese, grated
- 1/3 cup parmesan cheese, grated
For the gremolata –
- 1/2 cup flat-leaf parsley leaves, chopped
- 1 garlic clove, crushed
- Zest of 1 lemon
Instructions
- Melt the spicy paste. Set a large high-sided pan or saucepan over medium heat. Add 1 tablespoon of olive oil and 4 tablespoons of ‘nduja paste or gochujang paste Cook, stirring for 2 minutes as the paste melts down into the oil.
- Make the mac and cheese. At this point, add 2 1/2 cups of milk, 1 cup of hot stock, the dried pasta, 2 crushed garlic cloves and 1 teaspoon of salt. Stir everything and bring it to a simmer. Turn the heat down to low and cook, stirring occasionally, for about 12 minutes, until the pasta is al dente (cooked, with a little bite to it) and the sauce has thickened from the pasta starches. It will still be quite saucy at this stage – the cheese will thicken it up more. PRO TIP: Depending on the pasta shape youโre using, you may want to add a little more milk at this point, depending on how you like your mac and cheese.
- Make the gremolata. In a small bowl, mix the parsley, lemon zest and garlic. Set aside.
- Finish and serve. Once the sauce has thickened, add all the cheese and stir it through as it melts and forms a gorgeous, cheesy sauce then remove from the heat. Spoon the herby, zesty gremolata all over the top of the mac and cheese and serve while hot, oozy and gooey. PRO TIP: If you use an ovenproof skillet, you can pop the mac and cheese under the broiler (grill) for about five minutes to crisp up the top, or you can transfer it to an oven dish. If you do this, keep a little cheese aside to scatter on top before you put it in the oven.
Notes
If you are using an oven-proof skillet, I sometimes like to pop the mac and cheese under the grill (broiler) for 5 minutes at the highest temperature, for the top to crisp up nicely. If you want to do this, set about 1/4 cup of cheddar cheese aside then scatter it on top before popping it under the grill.ย
INGREDIENT NOTES: If you can’t find ‘nduja or gochujang, harissa paste is a good substitute. It’s also vegetarian. Taste it before you use it as different brands of harissa have different levels of spice – start with 2 tablespoons of harissa paste if yours is particularly spicy. You could also use sriracha, or use finely chopped chorizo or another spicy sausage. You can play around with your cheeses here too – use all cheddar if you like, or your favorite cheese. Try to make sure it’s a nice, strong-flavored cheese so you can really taste it in the sauce. I’ll often add some creamy blue cheese! Skip the gremolata if you like – it provides a lovely zesty element that cuts through the richness of the mac and cheese but it’s equally as wonderful without it. Or, sprinkle over scallions and crispy onions.
MAKE AHEAD: If you want to make the mac and cheese ahead of time, you’ll need to add a little liquid to it as you reheat it. You can either reheat it on the stovetop or in the microwave. I like to add a couple of tablespoons of water, just to help the sauce loosen up. The pasta will keep absorbing liquid as it cools which is why you’ll need to do this.
STORAGE INSTRUCTIONS: The mac and cheese will keep well for five days in the fridge stored in an airtight container. Store any leftover gremolata separately and spoon it over the top after you’ve reheated the pasta.
