Melt the butter in a small saucepan over medium heat.
Add the minced garlic and cook until fragrant, about 1-2 minutes, stirring constantly.
Remove from heat and season with about 1/4 tsp kosher salt, 1/8 tsp pepper, and parsley if using. Adjust seasoning to taste.
Serve immediately or keep warm until ready to use.

Notes
For the best flavor, use fresh garlic instead of pre-minced garlic.This sauce is versatile; try adding fresh herbs like parsley or basil for extra flavor. Serve over pasta, steamed vegetables, or use as a dipping sauce for bread.If you don't have lemon juice, a splash of white wine or vinegar can be used as a substitute.Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove or in the microwave before serving.The lemon juice adds a nice brightness and balances the richness of the butter.However, it's optional. If you prefer a straightforward garlic butter flavor, you can omit it. The sauce will still be delicious without it.
