How to get a casserole heated up quickly?

Question

My moms out of town so I'm making dinner. Well a frozen casserole she made before she left. Should I leave the foil on or take it off? I have had it in for at least 45 min. with the stove turned at 350 and the center is still a little frozen. Should I turn it higher?

Answer 1

use a blow torch

Answer 2

Take the foil off and put it on bake at 450-watch it to make sure it doesn't burn, but I'd say leave it in there at least 20 minutes.  

Answer 3

I would have left the foil on but thats just me. Just leave it on for a little bit longer, don't turn it up.

Answer 4

take the foil off. it may just need a while longer to cook. you could turn it to 375, but i wouldnt go any higher, because then it wont cook evenly, the outside will get burnt, the inside will be cold still.

Answer 5

if it's still cold, cut your serving and microwave it
