Preheat the oven to 350 F.
Season the short ribs on all sides with salt and pepper.
Using a large, deep dutch oven heat the avocado oil over medium heat. Once the oil is shimmering, add the short ribs and cook for 4-5 minutes on each side or until browned and crisp. Set aside.
Reduce the heat and add the sliced onion. Allow to cook for 10-12 minutes, just enough for the onions to soften, but not fully caramelize. Salt the onions and add the garlic, cooking for another few minutes.
Add the wine and scrape the bottom of the pot, bring to a simmer for 4-5 minutes before adding the short ribs to the pot. Pour over the broth, coconut aminos, and add the herbs. Cover and transfer to the oven.
Cook in the oven for 3 - 3 1/2 hours, or until the short ribs easily shred. I recommend removing from the oven every hour or so to gently stir and prevent any burning if your oven runs hot.
Once tender, remove from the oven and carefully remove the herbs and bay leaves. Whisk the arrowroot starch with about 2 tbsp of water or broth, and add it to the pot. Stir to allow the liquid to thicken.
Allow to rest before serving the short ribs with a side of mashed white sweet potato, or gluten free toast!
