Before you start
What this method is trying to achieve
The final two minutes matter more than simply spooning sauce onto drained noodles. Move the pasta into the sauce before it is fully cooked, add a little starchy cooking water and finish the pasta while stirring so sauce and starch bind together.
Success looks like
Know the target before you cook
The tomato sauce should coat the spaghetti evenly, with no watery pool underneath and no bare noodles.
Ingredients
What you need
Sauce
- 60 ml olive oil — About 1/4 cup.
- 1 small yellow onion, finely diced
- 2 cloves garlic, minced
- 800 g crushed tomatoes — About one 28-oz can.
- 1/4 tsp red pepper flakes — Optional.
Pasta
- 340 g spaghetti — About 12 oz.
Finish
- 14 g unsalted butter — About 1 tablespoon.
- 1 handful fresh basil leaves, torn
- 30 g Parmesan, finely grated — For serving.
Method
Cook by the cues, not just the clock
Build sauce
Heat the olive oil over medium heat. Cook the onion and garlic with a pinch of salt until softened, then add red pepper flakes and tomatoes.
Simmer
Simmer the tomato sauce gently while the pasta water comes to a boil, stirring occasionally.
Undercook pasta slightly
Cook the spaghetti about 2 minutes less than the package's full al dente time. Reserve at least 240 ml / 1 cup pasta water.
Finish in sauce
Move the spaghetti directly into the tomato sauce with about 60 ml / 1/4 cup pasta water. Stir and toss 2 to 3 minutes until the pasta finishes cooking and the sauce coats it.
Finish off heat
Remove from heat, stir in butter and basil and drizzle with a little olive oil. Serve with Parmesan.
Critical checkpoints
Stop here and check
Before transfer: pasta slightly underdone?
The spaghetti needs roughly 2 more minutes to reach the final bite.Transfer now so the last cooking happens in sauce.
During finishing: sauce coating the pasta?
The tomato sauce adheres to the noodles instead of collecting only at the bottom.Toss actively with a little starchy pasta water.
Sauce slides off noodles?
Noodles stay bare while sauce pools in the bowl or pan.Use CookClue's pasta-sauce-wont-cling diagnosis to check rinsing, starch, finishing and sauce consistency.

After cooking
Storage, reheating & substitutions
Storage
Refrigerate promptly in a covered container.
Reheating
Reheat gently with a small splash of water so the sauce loosens and recoats the noodles.
Substitutions
Good canned crushed tomatoes can be used year-round; spaghetti, bucatini or similar long pasta all work.

Food Network's pomodoro method uses a tomato-and-olive-oil base and finishes the pasta with the sauce so the noodles absorb flavor and become coated.
