This is delicious! Easy recipe for this inept cook. My husband loved it and told me to make more servings next time. He is a picky eater, too.
Jackie says
Could you omit the eggs or substitute that with something else? I have a sensitivity to eggs.
Jessica says
Hello! I'm wondering how much a serving size is in correlation with the nutrition facts?
Roche Woodworth says
Hi Jessica, the casserole is cut into 6 largish squares, so one square per person. I would estimate that one square is 1 - 1.5 cups per person. Hope that helps!
Michelle says
Hi, I made this earlier today and plan to reheat it for a late dinner tonight. I couldn't resist tasting it and it is delish! My question is, there seems to be a lot of liquid in the bottom of the casserole. Is it supposed to be that way?
Roche Woodworth says
Hi Michelle, we’ve never had the liquid issue - I’d say it should be slightly “saucy” at best. When I cook the veggies in a skillet, I tend to let them go until the water released from the mushrooms have cooked away. That’s the only place I can think of where extra liquid might come from. Not sure if that helps or not!

Roche Woodworth says
