Boil your pasta in salted water until al dente. Don’t overcook; we’re sauced, not mushy.
Meanwhile, melt butter in a skillet over medium heat. Add minced garlic and sauté for about 30 seconds until fragrant.
Pour in the heavy cream. Bring it to a gentle simmer, then reduce heat to low. Don’t boil vigorously—nobody wants a curdled romance.
Whisk in the Parmesan cheese a little at a time until the sauce is smooth and luscious. If it clumps, lower the heat and keep whisking.
Season with salt, pepper, and a pinch of nutmeg if you’re feeling fancy. Taste and adjust like a pro.
Drain the pasta and toss it straight into the sauce. Stir to coat evenly and heat through for another minute or so.
Serve immediately, with a sprinkle of parsley or chives if you’re feeling fancy. Optional: top with extra Parmesan.
