Ingredients
Method
Preparation
- Preheat your oven to 375°F (190°C).
- Split and lightly toast the English muffins; tear them into 1-inch pieces.
- Cut the roast beef into 1/2-inch cubes.
- Grease a 9x13 inch baking dish with the softened butter.
- In a large bowl, whisk together the 8 large eggs until well combined.
- Add in the 2 cups of whole milk (or half-and-half), 1 tablespoon Dijon mustard, salt, black pepper, and paprika. Whisk until smooth.
- Layer half of the toasted muffin pieces into the greased dish. Top with half of the cubed roast beef.
- Repeat with the remaining muffin pieces and roast beef. Pour the egg mixture over the layers, gently pressing down to ensure everything is soaking.
- Cover and refrigerate for at least 30 minutes, or preferably overnight.
Making Hollandaise
- Combine 3 egg yolks, lemon juice, Dijon mustard, salt, and cayenne in a blender.
- Blend while slowly pouring in the hot melted butter until thick and creamy.
Baking
- Remove the casserole from the fridge 15-20 minutes before baking.
- Bake covered for 30 minutes, then uncover and bake for another 20-30 minutes, until golden brown and puffed.
- Let it rest for 5-10 minutes before slicing. Serve topped with Hollandaise sauce and a sprinkle of chives or parsley.
