Pasta sticks together when it is cooked in too little water or not stirred in the first couple of minutes. As pasta hits hot water it releases starch and softens, and without room and movement the pieces glue together. Use a large pot of well-salted boiling water and stir early.
Pasta sticks = too little water or no early stirring. Fix: use a big pot at a rolling boil, salt it, stir for the first 2 minutes, and do not rinse.
Why It Clumps
- Not enough water, so pasta crowds and releases concentrated starch.
- No stirring in the first two minutes, when pasta is softening and sticky.
- Adding pasta before the water is at a full rolling boil.
How to Cook Non-Sticky Pasta
Use about 4 to 6 quarts of water per pound of pasta and bring it to a full rolling boil before adding the pasta. Salt the water generously, then stir for the first two minutes and occasionally after. Skip the oil, which just makes sauce slide off, and do not rinse cooked pasta unless you are making a cold salad. A roomy saucepan or stockpot gives the pasta space to move.
Frequently Asked Questions
Should I add oil to pasta water?
No. Oil floats on top and does little to stop sticking, but it coats the pasta when you drain it and stops sauce from clinging. Use plenty of water and stir instead.
Should I rinse pasta after cooking?
Only for cold pasta salads. For hot dishes, the surface starch helps sauce stick, so drain but do not rinse.
