Soften or melt the butter: If you want a dipping sauce, gently melt the butter until just fluid, not sizzling. For a spreadable sauce, let it soften at room temperature.
Prep the aromatics: Finely mince or grate the garlic. Chop the parsley and chives.
Zest the lemon, then squeeze the juice.
Build the base: In a medium bowl, combine butter and olive oil. Whisk until smooth and glossy.
Add flavor: Stir in garlic, Dijon, lemon zest, lemon juice, parsley, chives, red pepper flakes, smoked paprika, and Worcestershire. Add a small drizzle of honey if you like a balanced finish.
Season: Add salt and pepper to taste.
Start light, then adjust after a quick taste.
Rest for 5 minutes: Let the sauce sit so the flavors mingle. If it thickens too much, warm it gently over low heat or in short bursts in the microwave.
Serve: Pour into a small bowl for dipping or spoon over hot steak, chicken, shrimp, roasted potatoes, or grilled vegetables.
