Bring a large pot of salted water to a boil and cook the lentil pasta according to package instructions until al dente.

Melt the butter in a large skillet over medium heat while the pasta cooks.

Add the minced garlic to the skillet and sauté for 1 minute until fragrant.

Drain the pasta, ensuring you reserve a small amount of the starchy pasta water.

Toss the cooked pasta into the skillet with the garlic butter, then add the parmesan cheese and a splash of reserved pasta water.

Stir everything together until the pasta is coated in a smooth, glossy sauce and serve warm.
