Shopping list for this chapter
The basics
Cheese and egg sauces fail for one reason: too much heat. Cheese proteins tighten and squeeze out their fat if they get too hot, so the sauce turns into a stringy lump sitting in oil. Egg proteins set solid and scramble. Both sauces rely on a handful of tricks to keep the heat just right.
| Trick | How | Why |
|---|---|---|
| Add cheese or egg off the heat | Take the pan off before adding it | The pasta's own heat is enough, and it can't overshoot |
| Grate finely | Use the small holes, or buy freshly grated | Fine shreds melt before they overheat |
| Use starchy pasta water | A tablespoon at a time while tossing | Starch and water bind the fat into a smooth sauce, and cool the pan slightly |
| Let the steam calm down | Wait 20 to 30 seconds before adding egg | A pan that is too hot scrambles the egg |
| Toss constantly | Keep everything moving | Prevents hot spots where egg or cheese catches |
If a sauce starts to split or scramble, take it off the heat at once and add a splash of cold water and keep stirring. It often comes back.

Cacio e pepe (cheese and pepper)
"Cheese and pepper" is the simplest cheese sauce there is, and the best lesson in why cheese clumps. Cheese melts into a smooth sauce when it is moderately warm and wet, and goes stringy and lumpy when it is too hot or too dry.
Ingredients (1 portion)
- 75 g dried spaghetti or tonnarelli
- 40 g pecorino romano (or parmesan), very finely grated
- ¾ tsp coarsely ground black pepper
- 1 pinch salt (for the pasta water)
- Boil the pasta in a small amount of salted water (about 600 ml), which leaves the water extra starchy. Cook for the packet time minus 2 minutes.
- While it cooks, toast the pepper in a dry frying pan over a medium heat for 30 seconds until fragrant. Add 4 tablespoons of the pasta water and let it bubble, then turn the heat off.
- Put the grated cheese in a bowl with 2 tablespoons of the pasta water and stir to a thick, creamy paste.
- Lift the pasta into the pepper pan and toss for 30 seconds. Take the pan off the heat and let it cool for 20 seconds.
- Add the cheese paste and toss vigorously, adding pasta water a tablespoon at a time, until you have a glossy creamy sauce. Serve at once.
Finely grated, and off the heat
Grate the cheese as finely as you can (use the small holes), or buy it freshly grated. Pre-grated tubs have anti-caking powder that stops it melting smoothly. And always add cheese off the heat.
Level 2 · Cream
Lemon and parmesan cream pasta
A cream sauce is easier than a cheese sauce because the fat in the cream protects it from splitting. The lemon cuts the richness.
Ingredients (1 portion)
- 75 g dried tagliatelle or linguine
- 60 ml single cream or half-fat crème fraîche
- ½ lemon, zest and 1 tsp juice
- 25 g parmesan, finely grated
- 1 tsp butter
- 50 g frozen peas (optional)
- 1 pinch black pepper
- Boil the pasta in salted water, adding the peas (if using) for the last 3 minutes. Scoop out a mugful of water, then drain.
- In a wide pan over a low heat, warm the butter, cream and lemon zest for 1 minute. Don't let it boil.
- Add the pasta and 3 tablespoons of the cooking water and toss for 30 seconds. Take the pan off the heat and add the parmesan, lemon juice and pepper. Toss until creamy.
A lighter way
Half-fat crème fraîche, or even 2 tablespoons of ricotta loosened with pasta water, works instead of single cream. Both are less rich and less likely to split if the sauce gets hot.
Level 3 · The classic
Carbonara
A real carbonara has no cream. The sauce is egg and cheese, thickened by the heat of the pasta. Once you can make this without scrambling the egg, you can make any egg-based sauce.
Ingredients (1 portion)
- 75 g dried spaghetti
- 40 g smoked pancetta or lean bacon, diced
- 1 Lion-marked medium egg
- 20 g pecorino or parmesan, finely grated
- 1 tsp olive oil
- ½ tsp coarsely ground black pepper
- Beat the egg in a bowl with the cheese and pepper until smooth. Have a mug ready for the pasta water.
- Heat the oil in a wide frying pan over a medium heat and cook the pancetta for 5 to 6 minutes, until golden and crisp. Take off the heat.
- Boil the spaghetti in salted water for the packet time minus 1 minute. Scoop out a mugful of the water, then drain.
- Add the spaghetti to the pancetta pan, off the heat. Toss, then wait 30 seconds for the steam to calm down.
- Pour in the egg mixture and add 3 tablespoons of the pasta water. Toss quickly and constantly for 30 to 60 seconds, until the egg thickens into a creamy sauce that coats the pasta. Add more water if it is thick. Eat at once.
The egg
The egg is not cooked in a pan: it is warmed by the hot pasta to a thick, creamy sauce. Use Lion-marked eggs, which the Food Standards Agency says are safe to eat raw or lightly cooked, including for pregnant women, babies and older people. Keep the egg in the fridge until the last minute. Other eggs are not covered by that advice.
Level 2 · Healthy
Spinach and ricotta pasta
Ricotta gives a soft, creamy sauce without cream, and spinach wilts in seconds in the heat of the pasta.
Ingredients (1 portion)
- 75 g dried rigatoni or penne
- 100 g baby spinach
- 80 g ricotta
- 15 g parmesan, grated
- 1 tsp olive oil
- 1 garlic clove, finely chopped
- 1 pinch nutmeg
- ½ lemon, zest only
- Boil the pasta in salted water. Scoop out a mugful of the water before you drain.
- Warm the oil in a wide pan over a low heat and soften the garlic for 30 seconds. Add the spinach and a splash of pasta water and stir until wilted (about 1 minute).
- Add the drained pasta, ricotta, nutmeg, lemon zest and 3 tablespoons of the pasta water. Toss over a low heat for 1 minute until creamy.
- Off the heat, stir in the parmesan.
Experiments
Experiment
Cheese on or off the heat
See why you take the pan off the stove.
- Make cacio e pepe twice. In the first, add the cheese paste with the pan over a low heat. In the second, take the pan off the heat first, as in the recipe.
- Compare how smooth each sauce is.
Look for: On the heat the cheese tends to clump into strings, off the heat it blends into a smooth sauce. This applies to every cheese sauce.
Experiment
Carbonara: wait or pour at once
How hot is too hot for the egg?
- Make carbonara twice. In one, pour in the egg straight from the hot pan. In the other, wait 30 seconds, as in the recipe.
- Look at the sauce and taste.
Look for: The egg poured into a very hot pan scrambles into little curds. Waiting gives a smooth sauce. Now you know what too hot looks like.
Experiment
Full-fat or lighter cream
Does the lighter option work?
- Make the lemon cream pasta twice, once with single cream and once with half-fat crème fraîche (or ricotta loosened with water).
- Taste both, noting the richness and how smooth each is.
Look for: The lighter version has a fresher, tangier taste. Which would you pick for a weeknight?

Troubleshooting
| Problem | Likely cause | What to do |
|---|---|---|
| Cheese clumps into strings | Pan too hot, cheese too coarse, or too little water | Take off the heat, add pasta water, grate finer next time |
| Scrambled egg in carbonara | Pan too hot when the egg went in | Wait 30 seconds off the heat; toss fast; add cold water to rescue it |
| Sauce thin and watery | Too much pasta water | Toss over a very low heat for 20 seconds, or add a little cheese |
| Sauce too thick and sticky | Too little water | Add pasta water a tablespoon at a time |
| Too salty | Salty cheese plus salty pancetta | Use less salt in the pasta water, and taste before adding more |
| Grainy ricotta sauce | Ricotta heated too much | Add it off the heat and loosen with water |
Food safety: egg and cream sauces
Use Lion-marked eggs for carbonara, as explained above. These sauces are best eaten at once and don't reheat well: eggs and cheese turn grainy. Cooked pasta is a starchy food, and like rice it can grow bacteria if it is left warm. There is no pasta-specific official guidance, so this course uses the cautious rule: cool it quickly (within about an hour), put it in the fridge, and eat it within 24 hours; freeze it if you won't. Reheat until steaming hot all the way through.
Checkpoint: can you do this now?
- I can make a smooth cheese sauce without it clumping.
- I know why sauces with cheese or egg go off the heat.
- I can make carbonara without scrambling the egg.
- I can use pasta water to adjust a sauce.
- I know a lighter swap for a cream sauce.
