24-Hour Omelet

Serves 6 to 8 (at least)

3 tablespoons unsalted butter , softened, plus extra for greasing the dish
10 slices high-quality white sandwich bread
12 ounces cheddar cheese , shredded (3 cups)
8 large eggs
3 cups whole milk
1 onion , grated
1 teaspoon kosher salt
1 teaspoon ground black pepper
1 teaspoon dry mustard
1/2 teaspoon Tabasco sauce

1. Grease the bottom and sides of a 9 by 13-inch baking dish (or casserole dish of similar size) with butter. Spread the remaining 3 tablespoons butter over one side of each slice of bread, then cut the bread into 1-inch pieces. Scatter half of the bread evenly into the prepared dish and sprinkle with half of the cheddar. Repeat with the remaining bread and cheddar.

Whisk together the eggs, milk, onion, salt, pepper, mustard, and Tabasco and pour evenly over the bread. Press lightly on the bread to submerge. Cover tightly with plastic wrap and refrigerate for at least 8 hours.

2. Adjust an oven rack to the middle position and heat the oven to 350 degrees. Remove the dish from the refrigerator and uncover. Bake until puffed and golden brown, about 1 hour. Serve immediately.

  1. Do you have a note about the bread? This looks similar to a combination of the two in my blog :) Looks SUPER yummy! I might try it this weekend...what's the bread note though? :)

  2. I deleted the note - it suggests using Pepperiage Farm white bread but that brand has been hard for me to find so I just use nice quality white bread and it turns out great.
