Prepare your aromatics: Start by finely chopping your fresh parsley, chives, and thyme. Mince the garlic cloves (microplaning ensures the smoothest texture and best flavor dispersion) and finely mince the shallot. Uniform size is key here, as it ensures all flavors are evenly distributed throughout the butter.
Ensure butter is perfectly softened: It's crucial that your unsalted butter is at true room temperature, not just slightly soft. Soft butter is much easier to work with and ensures a smooth, homogenous compound butter without any stubborn lumps.
Combine all ingredients: In a medium mixing bowl, combine the softened butter with all the prepared herbs, minced garlic, minced shallot, lemon zest, fresh lemon juice, Dijon mustard, prepared horseradish, Worcestershire sauce, smoked paprika, red pepper flakes, cayenne pepper (if using), freshly ground black pepper, and sea salt.
Mix thoroughly: Using a sturdy spatula or a stand mixer with the paddle attachment on low speed, mix all the ingredients until they are thoroughly combined and the mixture is uniform in color and texture. Keep scraping down the sides of the bowl to ensure everything is incorporated. Thorough mixing guarantees that every bite of your Cowboy Butter delivers the full, incredible flavor profile.
Form and chill (for compound butter): Scrape the finished Cowboy Butter mixture onto a sheet of plastic wrap or parchment paper. Using the paper as a guide, roll the butter into a tight log, about 1.5 to 2 inches in diameter. Twist the ends of the wrap to seal. Refrigerate for at least 1-2 hours, or until the butter is firm enough to slice easily. Chilling not only helps the butter hold its shape but also allows the myriad of flavors to meld beautifully.
Melt and serve (for dipping sauce option): If you prefer a melted dipping sauce, simply scoop your desired amount of Cowboy Butter into a small saucepan. Melt it gently over very low heat, stirring occasionally, until it's smooth and liquid. Be careful not to overheat it, as gentle warming preserves the fresh flavors of the herbs and prevents the butter from separating. Serve immediately.
Serve and enjoy: Once firm, slice your chilled compound butter into rounds and place them directly on hot, freshly cooked steaks, seafood, or roasted vegetables. The butter will melt into a luscious, flavor-packed sauce. For the dipping sauce, simply pour it into a small ramekin and serve alongside your meal. Witness how this vibrant butter elevates your dish, making it shine with gourmet appeal!
