Make-Ahead Shrimp and Cheese Brunch Casserole

1. Butter an 8x8-inch casserole dish.

2. Use remaining butter to lightly butter bread. Cut each slice in half diagonally. Arrange 1/2 of the bread in the prepared dish. Sprinkle with half of the Swiss cheese, 1/2 of the green onions, 1/2 of the parsley, and 1/2 of the shrimp, in that order. Top with remaining bread and sprinkle with remaining cheese, onions, parsley, and shrimp.

3. Beat milk, sour cream, eggs, Dijon mustard, and salt together in a bowl. Pour over casserole, cover, and refrigerate for 8 hours, to overnight.

4. Preheat the oven to 350 degrees F (175 degrees C).

5. Bake casserole in the preheated oven until puffed and golden, 30 to 40 minutes. Let sit for 5 minutes. Cut into squares and serve.

Cook's Notes:

Could substitute ham or back bacon for shrimp, aged Cheddar for Swiss cheese, whole wheat or French for white bread. You can use dry mustard instead of Dijon.

If you prefer, dip bread in melted butter and don't butter pan.
