Food Network star Molly Yeh shares her take on the classic Midwestern meal called hotdish, a creamy casserole made with ground beef, veggies + Tater Tots.
Arrange a rack in the upper third of the oven and preheat the oven to 450°F
Heat a large skillet over medium-high heat and add the oil
Add the shallots and a pinch of salt and cook, stirring, until softened, 5 to 7 minutes
Add the ground beef and season it with 1 teaspoon salt
Brown the beef, breaking it up with a wooden spoon or spatula
Stir in the green beans and cook for a few minutes, until thawed
Use a slotted spoon to transfer the mixture to a 9 x 13-inch casserole dish and spread it out evenly
Set aside while you make the creamed soup
Discard the juices that remain in the skillet, wipe it out, and return to medium heat
Melt the butter and whisk in the flour to make a paste
Cook, whisking, for 2 minutes
Whisk in the pale ale, then add the chicken stock very gradually, in 3 or 4 additions, whisking continuously and allowing the mixture to thicken before each addition
Whisk in the heavy cream, a bunch of turns of black pepper, the thyme, and the nutmeg
Increase the heat and continue whisking frequently until it just begins to simmer, then reduce the heat to low and simmer very gently for 5 minutes, whisking occasionally
Taste and adjust the seasoning as desired
Pour or ladle the mixture all over the ground beef and fold together to incorporate
Top with perfectly aligned rows and columns of Tater Tots (adding a layer of cheese under or over the tots, if desired) and season with salt and pepper
Bake until the tots are golden brown and crispy on top; begin checking for doneness at 35 minutes (or a few minutes earlier if you have cheese on top)
If you want to get the tots even crispier, finish with a few minutes under the broiler
Let cool slightly, top with parsley, and/or serve with ketchup, if desired
TO MAKE AHEAD: Complete the steps up through topping with tots (and cheese, if using), assembling in a 9 x 13-inch metal casserole dish
Let cool, wrap in plastic or foil, and refrigerate or freeze until ready to cook
It'll last 2 days in the refrigerator and 3 months in the freezer
If reheating from the fridge, proceed as directed, but add on a few more minutes in the oven to ensure that it's heated through
To reheat from frozen, cover loosely with foil and bake at 350°F for an hour, then uncover, increase the heat to 450°F, and bake until the tots are golden brown and the innards are heated through; begin checking for doneness at 20 minutes
Let cool slightly, top with parsley, and/or serve with ketchup, if desired
