How to Prevent Pasta from Sticking: Expert Tips
Quick take: Use plenty of water, stir immediately, and never rinse unless making cold pasta salad.
Use enough water: 4-6 quarts per pound of pasta. Crowded pots mean clumping.
Salt properly: 2 tablespoons salt per gallon after it boils, before adding pasta.
Stir immediately: Within 30 seconds of adding pasta, stir once or twice.
Don't add oil: It prevents sauce from clinging to pasta. Exception: if your pot boils over.
Reserve pasta water: Scoop 1-2 cups before draining. This starchy liquid helps emulsify sauces.
Never rinse: Rinsing removes starch that helps sauce cling. Only rinse for cold pasta salads.
