Add the softened butter to a medium bowl. Beat with a fork until smooth and creamy.
Add the garlic, parsley, chives, Dijon mustard, lemon juice, smoked paprika, red pepper flakes, black pepper, and salt.
Mix until all ingredients are fully incorporated and the butter is uniform in color.
Serve immediately as a melting sauce over hot steak, or roll into a log using plastic wrap and refrigerate until firm.
Notes
- Butter must be fully softened — not melted — for the right texture. - Roll into a log and freeze for up to 2 months. Slice off rounds as needed. - Works on steak, grilled chicken, shrimp, corn, and crusty bread.
