Why is my pasta oily?

If your buttered noodles turn out oily or the sauce separates, it usually means the butter and pasta water didn’t emulsify properly. Butter is fat and naturally wants to separate from water. To avoid this, make sure you add some starchy pasta water, use cold butter, keep the heat low, and stir or whisk as the butter melts. This helps the fat and water combine into a silky, glossy sauce that clings to every noodle instead of sitting on top.

Cold butter helps create an emulsion when mixed with the pasta water. If you add melted butter, it just floats on the water and separates, leaving a greasy layer. Cold butter slowly melts into the starchy water, combining fat and liquid into a silky, glossy sauce that actually clings to the noodles.

Instructions

Bring a pot of water to a boil. Use slightly less water than usual so the pasta water becomes extra starchy.
Cook the pasta 1 minute less than the package instructions.
While the pasta cooks, heat a large pan over medium-low heat. Add the pasta water and reduce heat to low. Add the cold cubed butter and whisk vigorously until emulsified and glossy. A light simmer is fine.
Once the sauce is thick enough to coat the back of a spoon, turn off the heat. Stir in the soy sauce, then add the drained pasta and toss to coat.
Adjust the sauce as needed by adding more pasta water if it’s too thick, or return to low heat and toss until it thickens.
Finish with freshly cracked black pepper and grated parmesan. Enjoy!!
