Finely chop the shallot and sauté it in a small pan over medium heat until soft and lightly golden. Let it cool completely.
Soften the butter at room temperature.
In a bowl, combine the butter with the cooled shallots, minced garlic, chopped parsley, lemon juice, black pepper, and salt.
Mix until smooth and evenly combined.
Roll the butter into a log using parchment paper or transfer it to an airtight container.
Refrigerate for at least 1 hour before serving.
Slice or melt over meats, seafood, vegetables, potatoes, pasta, or bread.
