In a small saucepan, melt the unsalted butter over low heat. You can also use a microwave if you prefer. Be careful not to overheat the butter; it should just melt without boiling.

Once the butter is melted, stir in the minced garlic. Allow it to cook for a minute or two until fragrant. You can either keep the butter on low heat or remove it from heat after adding the garlic to prevent burning.

Add the Dijon mustard, lemon juice, paprika, cayenne pepper, salt, and black pepper to the melted butter. Whisk the ingredients together until well-combined.

Stir in the chopped parsley and chives. These fresh herbs will add a burst of flavor and a hint of color to your cowboy butter.

If you like your butter on the spicy side, add a pinch of red pepper flakes. Mix everything together one last time to ensure the flavors are evenly distributed.

Transfer the cowboy butter into a serving bowl. You can serve it immediately as a dip for steak, bread, or seafood. If you're basting meat with it, use a brush to coat your grilled meats for an extra layer of flavor.
