I've only tried it in the crockpot so far. It was really greasy. Like, digustingly so. Going to try baking it in the oven next. Will update after. :)
Update! Baked at 350° for 30 minutes covered and 15 minutes uncovered. It's soooooooooo much better this way!!!!!!!!!!! Not really greasy which was my biggest issue using the crock pot.
Update # 2: Does not taste nearly as good reheated.
Update # 3: 350° for 30 minutes uncovered. Then add a handful more cheese, 5-7 minutes broil low.
And if I forget the milk ONE more time, I'm gonna scream. Again. Lol.
