Green Rice

From Food52.
Ingredients:
Half a stick of butter, plus more for greasing the pan
2 to 3 bunches of spring onions - green onions or green shallots, or scallions - sliced into rings, green parts reserved
2 cups cooked white rice (or more, if you have it)
2 to 3 eggs, depending on how big they are and how much rice you have, beaten with a fork
1 to 1 1/2 cups milk
2 cups grated sharp cheese (recommended: Trader Joe's Unexpected Cheddar)
1 cup chopped parsley, tightly packed
Salt
Pepper

In a wide pan, heat half a stick of butter over medium heat. Add the white and light green onion slices to the pan and cook until they are golden and just begin to crisp up - you want a little bit of that burnt onion taste, but you still want some soft bits. Salt lightly, to taste.
Remove from heat, let cool slightly, and add the cooked rice, stirring to combine and coat the rice with butter and oniony bits. Stir in the eggs, plus enough milk to form a thick batter.
Add the cheese and parsley, plus a handful of the green onion parts, minced. Adjust the milk if necessary - it should be between gloppy and runny. Add salt and pepper.
Pour into a buttered ("ha ha as if it needed it") pie pan. The liquid should fill up to the level of the rice, so add more if it looks like it will burn or dry out while baking. Bake at 350° F until set, about 45 to 60 minutes. Slice it like a pie.
Serves 8-10.
