Preheat oven to 425º. Line a cookie sheet with foil or parchment paper and a baking rack and set aside.

In a large bowl, add ground beef, Worcestershire sauce, garlic powder and onion powder.

In a medium bowl, add milk. Tear bread pieces into small pieces and soak in milk for 1 minute. Using hands, stir bread into milk until it forms a paste.

Scoop bread portion of mixture (discard excess milk) and add to meat mixture. With hands, mix all contents together. Form two large patties about 1.5” thick. Sprinkle both sides of burgers with salt and pepper and set aside.

In a cast-iron pan or heavy-bottom skillet, over medium high heat, add 1 tbsp olive oil. Add hamburger steak patties. My skillet would only fit one patty. So I had to do them in two batches.

Turn heat down to medium and sear for 2 minutes on each side and then set on a prepared cookie sheet. If you want to keep the hamburger steak patties out of the grease – place a wire rack on the cookie sheet.

Place cookie sheet into the oven and bake for 15 minutes until hamburger steaks are cooked through.

While the chop steaks are baking, raise heat on skillet to medium high and add 2 tbsp olive oil.

Once oil is shimmering, add onions and mushrooms and saute until softened.

Remove chop steak from the oven and top each patty with a spoonful of mushrooms and onions. Top with half shredded jack cheese. Place back in oven for 5 min more for cheese to melt.

Open oven and test internal temperature of patties with an instant read thermometer. Steak patties should read 150º for medium doneness.
