This easy one-pot mac and cheese is packed with spicy paste—‘nduja or gochujang—for a supercharged, gooey, saucy dish without making a roux, using butter, or adding flour. Everything cooks in one pot and the pasta starch naturally thickens the sauce, so cleanup is minimal and the result is silky and flavorful.
Why This Mac and Cheese Recipe Works So Well
This method is a real game-changer. Traditional mac and cheese requires a roux-based sauce and cooking pasta separately. Here, everything goes into one pot: pasta, liquid, cheese, and spice. The pasta releases starch as it cooks, naturally thickening the sauce and creating a glossy finish—just stir and cook for about 20 minutes.
- The secret is the pasta starch.
- As the pasta simmers, starch leaches into the cooking liquid to thicken the sauce, eliminating the need for flour or butter. That same starch is why adding a splash of pasta water to other dishes helps bring sauces together.
- One-pot cooking also means less washing up—always a plus.
‘Nduja is the hero here: a spreadable, spicy, umami-rich salami from Calabria that melts into the sauce and delivers depth, heat, and a meaty finish. If you prefer a vegetarian alternative, gochujang works beautifully and gives a different but equally satisfying spicy-sweet umami character.
Ingredients You’ll Need
- Pasta: Cavatappi is used here, but any small shape—macaroni, fusilli, or penne—works well.
- Milk: Whole milk gives the creamiest result; 2% (semi-skimmed) is a fine substitute.
- Cheese: A blend of mature cheddar, gruyere, and parmesan melts into a rich sauce. Strong-flavored cheeses work best; a bit of blue cheese can be delicious if you like bold flavors.
- ‘Nduja paste: The key flavor component. If you can’t find it, substitute gochujang, harissa, sriracha, or finely chopped chorizo.
- Gremolata: Fresh parsley, lemon zest, and a touch of garlic brighten the dish and cut through the richness. Swap parsley for cilantro, scallions, or basil if preferred.
How to Make Spicy Mac and Cheese
- Add a little olive oil and the ‘nduja or gochujang to a large, high-sided pan over medium heat. Cook for a couple of minutes until the paste melts into the oil and becomes fragrant.
- Add the pasta, crushed garlic, milk, and hot stock or water. Stir well to combine and bring to a gentle simmer.
- Lower the heat and simmer, stirring occasionally, for about 10–15 minutes until the sauce has thickened from the starch and the pasta is al dente. The mixture should remain saucy—the cheese will finish the job.
- When the pasta is al dente, remove from the heat and stir in the grated cheeses until melted and smooth. Adjust the sauce with a splash more milk, stock, or water if you prefer it saucier.
- If you like a browned top, transfer the pan to a broiler-safe dish (or use an ovenproof skillet) and broil for a few minutes until the top is golden and crisp.
- Finish with the gremolata—parsley, lemon zest, and garlic—sprinkled over the hot mac and cheese and serve immediately while gooey and hot.
Spicy Mac and Cheese FAQs
Yes. The pasta will continue to absorb liquid as it cools, so store it in an airtight container for up to five days. Reheat on the stovetop or microwave, adding a few tablespoons of water, milk, or stock to loosen the sauce. Keep the gremolata separate and spoon it on after reheating.
Substitute gochujang or harissa paste for a vegetarian option. Harissa varies in heat, so taste first and start with less if it’s spicy. Sriracha, or finely chopped chorizo or another spicy sausage, are also good alternatives.
It has noticeable heat from ‘nduja or gochujang, but milk and cheese mellow the spice. Reduce the paste by a tablespoon or two if you prefer milder flavor.
Choose cheeses that melt well and have strong flavor. The recipe uses cheddar, gruyere, and parmesan, but fontina, gouda, havarti, Monterey Jack, or a creamy blue also work. Grate cheese yourself for the best texture—pre-shredded cheese can make the sauce grainy.
Whole milk gives the creamiest result, though lower-fat milk will still work if needed.
Yes. Cool completely, transfer to an airtight container, and freeze up to three months. Thaw overnight in the fridge or reheat gently, adding a little milk or water to loosen the sauce, then finish with gremolata.

Easy One Pot Spicy Mac and Cheese
5 from 1 review
- Author: Kate Phillips
- 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 meal without a roux, butter, or flour. Let the pasta starch do the thickening while you enjoy minimal cleanup and maximum flavor.
Ingredients
For the spicy mac and cheese –
- 1 tablespoon olive oil
- 4 tablespoons ‘nduja paste (or gochujang paste)
- 10.5 oz / 300 g dried pasta (cavatappi, fusilli, penne, or macaroni)
- 2 1/2 cups whole milk
- 1 cup hot chicken or vegetable stock
- 2 garlic cloves, crushed
- 1 teaspoon salt
- 1 cup mature cheddar, freshly grated
- 1/2 cup gruyere, freshly grated
- 1/3 cup parmesan, freshly grated
For the gremolata –
- 1/2 cup flat-leaf parsley, chopped
- 1 garlic clove, crushed
- Zest of 1 lemon
Instructions
- Melt the spicy paste. Heat a large high-sided pan over medium heat. Add the olive oil and the ‘nduja or gochujang. Cook, stirring, for about 2 minutes until the paste melts into the oil.
- Add milk, stock, and pasta. Pour in the milk and hot stock, add the dried pasta, crushed garlic, and salt. Stir, bring to a simmer, then reduce to low and cook, stirring occasionally, for 12–15 minutes until the pasta is al dente and the sauce has thickened from the starch.
- Make the gremolata. While the pasta cooks, combine parsley, lemon zest, and garlic in a small bowl and set aside.
- Add the cheese. Remove the pan from heat when the pasta is al dente and the sauce is slightly saucy. Stir in all the grated cheese until melted and smooth. Add a splash of milk, stock, or water if you prefer a looser sauce.
- Broil (optional). For a golden top, transfer to an ovenproof dish or use an ovenproof skillet, scatter extra cheese, and broil for a few minutes until crisp.
- Finish and serve. Spoon the gremolata over the mac and cheese and serve immediately while hot and gooey.
Notes
Ingredient notes: If ‘nduja or gochujang isn’t available, try harissa or sriracha, or use chopped chorizo. Taste and adjust quantities since spice levels vary.
Cheese tip: Grate cheese yourself for a smoother sauce—pre-shredded cheese often contains anti-caking agents that affect texture.
Toppings: Gremolata brightens the dish, but you can omit it or add crispy bacon, fried onions, scallions, chives, furikake, chili flakes, or panko crumbs for texture.
Make ahead & storage: Store leftovers in an airtight container in the fridge for up to five days. Reheat gently with a splash of water, milk, or stock. Freeze cooled leftovers up to three months; thaw overnight and loosen with liquid when reheating.
