Is there a reason why it would not work to cook these recipes with raw beef or raw ground beef? I know it is possible to put raw chicken just straight in with your other ingredients, but why do you recommend cooking the beef separately first? I am new to Instant Pot and don’t understand. Won’t the flavor be better if you cook the beef from raw with all of the other flavors? Thanks for these freezer dump meals. I think this is the solution to all my problems! hahaha.
@Sarah, I was wondering the same thing but you never got an answer!
