Cheesy Mushroom Bake

READY IN: 3hrs 20mins
Recipe by Always in the kitch

This is a nice side dish, for almost any meal. Similar to a stuffing. Flavors are best when it is refrigerated several hours or even overnight before baking. Mushroom lovers can experiment with different mushrooms. More can be added of desired.

I was looking for something mushroom and cheesy. I followed this recipe and my boyfriend loved it! I used half and half instead of milk and poured part of the milk egg mixture over the bread cubes first, so I didn't have to wait for everything to soak up. Also used a sage blend instead of mustard powder. Great recipe.
