Sauteed onions and mushrooms flavor this ground chuck meatloaf, which is layered with whole raw mushrooms before baking. These add a lot of juice to the loaf.
I make my meatloaves different every time, usually just going with what I have in the house. Must be why this is my THIRD meatloaf recipe! This one is definitely a keeper, though. I'll be making it just this way more often.
