Soften the butter on the counter or by setting it under a hot glass, and chop the herbs. When softened, combine butter, garlic powder, herbs and pepper in a bowl and mix to combine.
Spread the butter rub over the meat, making sure to cover all sides of the roast.
Prepare the roast, and serve! Save any spare rub (that hasn't been in contact with the meat!) for spreading on toast, vegetables, and more!
Notes
Fresh herbs are ideal, but if you're in a pinch, dried herbs will work too! Just limit the amount to about half, as dried herbs are more potent and too many can quickly become overpowering.
I prefer to use salted butter for a more flavorful rub. If using unsalted butter, add a little salt to the mix.
Make extra, and set aside a portion to store. This butter rub is essentially herb butter, and tastes incredible used in all sorts of ways! I like to add a little to the pan before cooking up sandwiches, or add it on top of mashed potatoes.
Spare butter can be stored in a container in the fridge or wrapped up into a log shape using plastic wrap.
Feel free to mix and match the herbs in this rub. You may prefer more thyme, more rosemary, or a mix of sage!
