Chop garlic cloves. Sprinkle with 1/4 teaspoon salt. Set aside to sit for about 10 minutes. After allowing garlic to sit, it should be tender enough to mash with a fork into a paste. Fully mash garlic.
In a small microwave-safe mixing bowl, add mashed garlic, butter, and parsley. Microwave for about 45 seconds, until butter is fully melted.
Once butter is melted, stir to incorporate all of the ingredients. Set aside.
