Fill a large pot with water and bring it to a boil. Add salt generously before adding the noodles. Cook according to package directions until tender. Drain well and set aside for later use.

Before draining the noodles, save about half a cup of pasta water. This simple step helps create a silky sauce later. The starchy water blends beautifully with butter and seasonings.

Place a large skillet over medium heat. Add the butter and allow it to melt slowly. The butter creates the rich base that gives these garlic noodles their signature flavor and texture.

Add the minced garlic to the melted butter carefully. Stir constantly for about one minute. The garlic should become fragrant but not brown. Burnt garlic can create a bitter taste.

Pour in the soy sauce, oyster sauce, brown sugar, sesame oil and black pepper. Stir everything together until smooth. The sauce should smell savory, slightly sweet and wonderfully rich.

Transfer the cooked noodles into the skillet carefully. Use tongs to toss them gently. Make sure every strand becomes coated with the flavorful garlic sauce for the best results.

Pour a small amount of reserved pasta water into the skillet. Stir gently while tossing the noodles. This helps create a smooth sauce that clings perfectly to every bite.

Sprinkle the Parmesan cheese over the noodles gradually. Toss continuously until melted and evenly distributed. The cheese adds creamy richness and makes the noodles extra comforting and delicious.

Stir in chopped parsley and sliced green onions just before serving. These fresh ingredients add color and brightness. They also balance the richness of the butter and cheese beautifully.

Transfer the garlic noodles into serving bowls while hot. Add extra Parmesan cheese if desired. Enjoy immediately for the best texture and flavor. Freshly made garlic noodles are always the most satisfying.
