Instructions
- Prepare the Dish: Grease a 9x13-inch baking dish with butter or non-stick spray. Spread the cubed English muffins in an even layer across the bottom. Sprinkle the diced Canadian bacon evenly over the muffins.
- Mix the Custard: In a large bowl, whisk together the 8 large eggs, whole milk, chopped green onions, Dijon mustard, salt, and pepper until everything is well combined and slightly frothy.
- Soak the Casserole: Pour the egg mixture evenly over the English muffins and Canadian bacon. Gently press down on the top with a spatula to ensure all the muffin pieces are submerged and soaking up the liquid.
- Chill Overnight: Cover the dish tightly with plastic wrap or a lid and refrigerate for at least 4 hours, or preferably overnight. This is the key step for the best texture.
- Bake the Casserole: When ready to bake, preheat your oven to 375°F (190°C). Remove the dish from the refrigerator and let it sit at room temperature for about 20 minutes. Sprinkle the top with paprika. Bake, uncovered, for 45-55 minutes, or until the center is set (a knife inserted in the middle comes out clean) and the top is golden brown.
- Make the Hollandaise: While the casserole is baking, prepare the sauce. Add the 3 egg yolks and lemon juice to a blender. Blend for just a few seconds to combine. With the blender running on low, slowly stream in the hot, melted butter. The sauce will thicken and emulsify. Season with cayenne and salt.
- Serve: Let the casserole cool for about 10 minutes before slicing. Serve warm, with a generous drizzle of the Hollandaise sauce over each portion.
Notes
For best results, toast the English muffin cubes before adding them to the dish to prevent a soggy bottom. The blender Hollandaise sauce can be made up to a day in advance and reheated by placing its container in a bowl of warm water and whisking gently. The casserole is done when a knife inserted into the center comes out clean. Substitutions are welcome: try ham or sausage instead of Canadian bacon, or add cooked vegetables like spinach for a vegetarian option.
