Chef John's Hamburger Hash
Move over corned beef, because there's a new hash in town! If you like hash, you are going to love this version made with ground beef instead of corned. Making a hash is basically a 3-step process: frying your meat and potatoes, adding onions and mushrooms, and then adding quick-cooking vegetables like peppers. But take a look in the fridge and use any ingredients you'd like because in the game of hash, whoever has the most ingredients wins! Top with a cayenne-dusted poached egg and green onions if you'd like.
You can use all butter or all olive oil if preferred. You can use fresh rosemary instead of dried, and green bell pepper instead of poblano.
You can brown the hash for as long as you'd like. I go for severe "crustification" which I believe improves the taste and texture.
To turn this into cheeseburger hash, stir in a nice big handful of sharp Cheddar cheese when you add the green onions.
