Bring a big pot of salted water to a boil. Toss in the pasta and cook until al dente, following the package directions.
While the pasta's working its magic, melt the butter in a large skillet over medium heat.
Add the minced garlic and stir it around until it smells so good you start drooling (about 1–2 minutes). Don’t let it burn!
Drain the pasta, but save about 1/2 cup of that starchy pasta water. You’ll need it!
Toss the hot pasta into the buttery garlic goodness. Stir it like you mean it.
Splash in some reserved pasta water to make everything silky and gorgeous.
Season with salt and pepper. Go wild or stay mild—your call.
Plate it up, sprinkle with parsley and a rainstorm of Parmesan, and dig in.
