Gemelli Pasta with Mushrooms and Pecans

Gemelli Pasta with Mushrooms and Pecans

Gemelli pasta is a short, twisted pasta shape. The name means "twins" in Italian, because each piece is two strands spiraled around each other. The shape is designed to catch and hold sauce in its ridges and coils, which makes it a natural choice for something thicker and more textured than a light tomato or oil-based sauce. This recipe takes advantage of that: a cream and parmesan sauce with wild mushrooms and toasted pecans, where the sauce clings to every coil and the pecans work into the gaps.

The combination sounds unusual until you taste it. Mushrooms and pecans share a deep, earthy quality, and toasting amplifies the pecans' natural oils so they taste roasted and almost meaty alongside the mushrooms. A small amount of fresh thyme keeps the dish from becoming too heavy. It is one of those weeknight pasta dishes that feels more deliberate than the effort suggests, ready in 35 minutes but with the texture and depth of something that took longer.

Why It Works

• Toasting the pecans dry before adding them to the pan develops their natural oils and gives them a roasted, nutty depth that raw pecans do not have. Under-toasted pecans taste flat next to the mushrooms; correctly toasted, they taste like part of the same earthy family.
• Wild mushrooms (cremini, shiitake, or a mix) have more flavor than button mushrooms because they have more complexity. Slicing them thickly and letting them sit undisturbed in the pan for the first few minutes allows a proper sear to develop rather than steaming them.
• Adding the cream after the mushrooms have browned prevents the cream from diluting the sear. The fond at the bottom of the pan gets lifted into the sauce when the cream hits the heat, which is where most of the flavor lives.
• Parmesan goes in off heat, with the pasta added first to bring the temperature down. This prevents the cheese from seizing and keeps the sauce smooth and coating.

On the Pasta Shape

Gemelli is one of the pasta shapes best suited to cream sauces because the twisted structure gives the sauce more surface area to cling to than a smooth tube or strand. If you cannot find gemelli, fusilli or cavatappi will work similarly: any short, twisted shape with ridges. Cook it in well-salted water and reserve a full cup of pasta water before draining. The starch-heavy water loosens the sauce if it tightens, the same principle behind a cacio e pepe, where pasta water is the only liquid in the sauce and there is no cream at all.

On the Mushrooms

Wild mushrooms is a loose term. For this recipe, it means anything that is not a plain white button mushroom. Cremini mushrooms are the most available option and work well. Shiitake, oyster, or chanterelle mushrooms will give more complexity. The key is not to overcrowd the pan: mushrooms release water as they cook, and if the pan is too full they steam rather than brown. Brown mushrooms have flavor; steamed mushrooms do not. Cook them in batches if needed, and season only at the end of the sear rather than at the beginning.
