In a medium mixing bowl, combine the softened butter with the minced fresh herbs (parsley, cilantro, chives, and oregano).
Add the minced garlic, crushed red pepper flakes, smoked paprika, lemon zest, sea salt, and black pepper to the bowl.
If you're looking to elevate the flavor, add the optional lime zest for that extra kick.
Using a spatula or your hands, thoroughly mix all the ingredients until they are well combined and the butter takes on a vibrant green hue.
Place a sheet of parchment or wax paper on a flat surface. Spoon the herb butter mixture onto the paper and shape it into a log or a block. Roll it tightly and twist the ends to seal.
Chill the roll in the refrigerator for at least 1 hour to firm up. For longer storage, you can freeze it for up to 3 months.
Once ready to use, simply slice rounds off the chilled butter to flavor up grilled meats, vegetables, or a slice of fresh bread, adding a delicious fiery herbaceous kick to your dishes.
