In a seperate skillet, heat the butter over med-low heat. Once melted, add the garlic and cook, stirring often for 3-5 minutes, until soft and fragrant. Be careful not to let it brown though, or it will turn bitter. Once it's ready, pour the garlic and butter over the drained pasta, season it with salt and pepper to taste, then toss to coat. That's it! Serve it up with lots of parmesan over the top.
