Saute Onion & Garlic:
Set browned chuck roast aside. Add in sliced onions, then saute until softened (~3 - 4 mins). Set aside roughly ⅓ of the softened onions for later. Add in minced garlic, a pinch of dried rosemary, a pinch of thyme, and 2 bay leaves. Saute for another minute.
*Pro Tip: Your Instant Pot will stop sauteeing after 30 minutes, turn it back on by pressing "Saute" button. :)
