Melt Butter and Infuse with Garlic: Heat butter in a small saucepan or skillet over medium heat. As it melts, add the minced garlic. Cook and stir until the garlic is tender and fragrant, about 1 to 2 minutes. Be careful not to let it brown.
Finish and Serve: Remove the pan from the heat and stir in the fresh parsley. Season with salt to taste and serve immediately.
Notes
Preventing Bitter Garlic: The main thing is to not burn the garlic. Cook it gently over medium or medium-low heat just until it smells fragrant. If it starts to brown, it will taste bitter. If you do burn it, throw it out and start over; unfortunately there's no way to fix it.
Storage: Store leftovers in an airtight container in the refrigerator for up to 5 days or store in the freezer for up to 3 months.
Creamy Pasta Sauce Variation: To make a thicker sauce for pasta, whisk 1 tablespoon of flour into the garlic and butter and cook for 1 minute. Slowly whisk in 1 cup of milk or heavy cream and simmer until thickened.
