Sorry I am a bit tardy in answering ~ we had a storm this afternoon that knocked our internet out in this region for a while ~~ anyway, I bake this in my vintage cast iron Griswold 10 inch skillet, which is very well seasoned. I would imagine it would be fine in a glass baking dish, since it doesn't "grow" during baking, you can use what ever you choose that it fits into . Usually if I bake in a glass dish, I will lower the oven temp to 325 degrees. We recently found a divine no-stick spray at Trader Joe's made from coconut oil that I have found works fabulous in glass or stoneware baking dishes. If after the addition of the extra veggies the mixture seems a bit too thick, you can always whisk together a couple of eggs and some extra half and half to add in . Thank you again and blessings to you ! ;-)
