Ingredients

  • 4 Brioche Buns
  • 8 Oz Corned Beef
  • 4 Hash Browns Store-bought or homemade
  • Small Yellow Onion Diced / About 1 Cup
  • 4 Large Eggs
  • 4 Slices American Cheese

Russian Dressing

  • 1/2 Cup Mayo
  • 2 Tbsp Ketchup
  • 1 Tsp Worcestershire Sauce
  • 2 Tsp Horseradish
  • 2 Tbsp Lemon Juice
  • 1/4 Tsp Salt
  • 1/4 Tsp Black Pepper
  • 2 Tbsp Pickle Relish

Instructions

  • In a small bowl add all the ingredients for the dressing and mix until combined. Refrigerate until ready to assemble the sandwich.
  • Get the instructions on how to make homemade hash browns here. You can absolutely use store-bought.
  • Preheat a non-stick pan to medium-high and add 1 tablespoon oil and 1 tablespoon unsalted butter. Add the diced onions and cook until starting to brown. About 5-8 minutes. Place in a bowl and set aside.
  • In a non-stick pan, melt 1 teaspoon butter on medium-low until bubbles start to form. Add the egg and cook until the egg whites start to set and the yolk is still runny. About 3-4 minutes. Sprinkle with salt, pepper, and fresh thyme (optional).
  • Slice the corned beef into strips and add it to a medium pan with 1 tablespoon of water. Put on the lid and heat through about 3 minutes.
  • Time to assemble, add the Russian dressing to the top and bottom bun. Then, add the sauteed onions, corned beef, hash brown, a slice of cheese, and egg. Continue until all sandwiches are made. Time to enjoy!

Notes

  • The dressing is delicious but will get even better if you can make it in advance. Preferably overnight.
  • If using store-bought frozen hash browns then heat them in the air fryer at 400 degrees for 8-10 minutes. 
  • You want to cut the corned beef against the grain.
  • We steamed the buns since we used store-bought and they weren't as soft as we'd like. 
  • Store the cooked corned beef in an air-tight container in the fridge for up to 4 days.
