I grew up with White Castles, but now live where we don't have them. I LOVE the taste of this. I have decided to tweak the recipe a bit. I mix everything together raw, like you would a meatloaf. Then I bake it in either 2 mini loaf pans or muffin tins. I bake them until browned (about 45 minute loaf pans, 30 minutes muffin pan). With the mini loaf pans, when you cut them, it almost looks like the square burgers. With the muffin pan, you just flip them out of the pan and they are ready to have as individual servings--very handy for freezing and when only mom is doing the low-carb thing.

What a great casserole. I'm not sure this tasted like White Castle, but it was really close and really good. I'm going to try to cut some fat out next time, since I went the opposite way last night. I had to change a couple of things, as I was lower on cheddar than I thought. I added shredded pepper jack to make up the difference, then figured since I was changing it up, may as well go all out, so I topped the meat with some bacon crumbles before pouring the liquid on top. Looked terrible, but tasted great. I'd suggest chopping the pickles a bit to top so each bite has some pickle taste to it. Will definitely make again, subbing some lower fat cheeses, maybe some ground turkey, etc... Thanks for sharing!

When I read this recipe, I was doubtful. It sounds disgusting. It even looks pretty gross. I don't know how the topping works, but it tastes just like a Krystal, bun included. I froze mine in individual portions so I could have it whenever the craving strikes. I seriously want to kiss Mercy for posting this recipe!
