Melt butter or heat oil in a pot on the stove over medium/low heat.
Slice your onions into thin slices, then add them to the pot and toss in the butter or oil.
Cook for 5 minutes, until softened, stirring often. Then, once they are soft, add the ¼ cup of broth along with some salt and pepper and continue cooking for another 5 minutes, stirring often. You'll know the onions are ready when the broth has evaporated and the onions are lightly golden and soft.
Stir the arrowroot into the onions to thicken them slightly.
Once fully combined, add in the garlic, beef broth, herbs, coconut aminos and additional salt and pepper. Allow to simmer on the stove for 10 minutes, or so.
Remove the herbs before serving.
