STEAKHOUSE SHEPHERD'S PIE

Steps:

• Place potatoes in a pot; cover with cold water and bring up to a boil. Season water with salt and boil potatoes until tender, 12 to 15 minutes. Heads up: save a ladle of starchy cooking water just before draining.
• Heat a skillet with high sides over medium high heat.
• Add extra-virgin olive oil, half a turn of the pan and add the bacon.
• Crisp bacon and remove to paper towel lined plate.
• Add sirloin to the pan and caramelize the meat, 4 to 5 minutes.
• Add in the mushrooms and onions and cook until tender, 6 to 7 minutes more; season with salt and pepper.
• While meat cooks heat a small sauce pot over medium heat and melt butter; whisk the flour into butter; cook 2 minutes; whisk beef stock into flour; add Worcestershire sauce.
• Season sauce with salt and pepper, to taste.
• Thicken 6 to 7 minutes.
• Pour gravy over meat.
• Turn on broiler.
• Temper egg yolk by beating it with the starchy potato cooking water.
• Place drained potatoes back into the pot you cooked them in to dry them out a little.
• Mash potatoes with egg yolk and sour cream then fold in crumbled blue cheese and chives.
• Season the potatoes with salt and pepper and spread across the top of the meat in an even layer.
• Garnish the potatoes with paprika.
• Place under broiler to crisp and brown the potatoes, 2 to 3 minutes.
• Serve immediately right from the hot skillet.
