Place half of the Canadian bacon in a greased 9x13 dish. Add English muffin pieces on top. Top with the rest of the bacon.
In a medium bowl whisk eggs and milk. Mix well and pour over the top. Refrigerate for at least 1-2 hours.
Preheat oven to 375.
Sprinkle paprika on top of the casserole, cover and bake for 30-35 minutes. Uncover and bake an additional 10-15 minutes.
In a small pot, whisk egg yolks, cream, lemon juice and mustard on LOW heat until blended. Stir constantly and cook until it reaches 160 degrees or enough to coat a metal spoon. Slowly add butter, whisking constantly and until well combined. Serve immediately with casserole. ENJOY!
