Ingredients
For the strata:
- 6 English muffins, split and cut in half
- 12 large eggs
- 2 cups whole milk
- 1/2 cup half-and-half
- 1 tsp. kosher salt, plus more to taste
- 1/2 tsp. black pepper
- 1 Tbsp. olive oil
- 8 oz. Canadian bacon sliced, quartered
- 1 10-ounce package baby spinach
- Salted butter, for the pan
- 2 1/2 cups grated white cheddar cheese (about 8 ounces)
For the Hollandaise sauce:
- 1 1/2 sticks (12 tbsp.) salted butter
- 3 large egg yolks
- Juice of 1/2 lemon
- 1/4 tsp. kosher salt
- 1/4 tsp. black pepper
- A few dashes of hot sauce
Directions
- Step 1For the strata: Preheat the oven to 425 ̊. Arrange the English muffins on a rimmed baking sheet and bake until golden brown, about 10 minutes. Let cool.
- Step 2Combine the eggs, milk, half-and-half, salt, and pepper in a large bowl and whisk to combine. Set aside.
- Step 3Heat the olive oil in a large skillet over medium-high heat. Add half of the Canadian bacon in a single layer and cook until browned, about 1 minute per side. Remove to a plate and repeat with the remaining Canadian bacon; add to the plate. Add half of the spinach to the pan and toss until partially wilted, then add the remaining spinach and toss until all the spinach is wilted. Season with a pinch of salt. Remove the spinach to a paper towel–lined plate and press with the back of a spoon to release some of the liquid.
- Step 4Butter a 9-by-13-inch baking dish. Layer half each of the English muffins, spinach, Canadian bacon, and cheese in the prepared dish. Repeat the layering with the remaining ingredients, ending with the cheese. Slowly pour the egg mixture over the top. Cover the baking dish with plastic wrap and refrigerate overnight.
- Step 5About 30 minutes before baking, remove the strata from the fridge. Preheat the oven to 350 ̊. Remove the plastic wrap and cover the dish with foil. Bake for 30 minutes, then uncover and continue to bake until golden brown and slightly crisp on top, 25 to 30 minutes more.
- Step 6Just before serving, make the hollandaise: Melt the butter in a small saucepan until sizzling. Remove from the heat. Meanwhile, add the egg yolks and lemon juice to a blender. Then, with the blender on, slowly drizzle the hot butter into the yolks. It’ll start to thicken right away. Add up to 1 1/2 teaspoons warm water to loosen the sauce until it is pourable. Stir in the salt, pepper and hot sauce. Drizzle some of the sauce over the strata and serve the rest on the side.
