- 2Reserve a full cup of pasta water before draining; its starch helps the sauce cling to the spaghetti.
- 3Do not rinse the cooked pasta — the surface starch is key for sauce adhesion.
- 4Bloom the dried oregano in the hot oil for 15 seconds to intensify its flavor before adding tomatoes.
- 5Simmer the sauce uncovered for at least 15 minutes to concentrate sweetness and thicken naturally.
- 6When combining pasta and sauce, toss with tongs rather than a spoon to coat evenly without breaking the noodles.
- 7Leftover pasta keeps for 3 days in the fridge; refresh with a splash of water when reheating.
