French Onion Burgers
1 Onion, chopped
2 Cups Beef Stock or Broth
Herbs de Provence
2 Brioche buns
Grated Gruyere or other Swiss cheese
Heat a deep sided skillet over medium high heat.
Season the burgers with pepper and salt.
Add enough beef broth that will cover the burgers – about 2 cups – and bring to a simmer.
Stir in 1 Teaspoon of Herbs de Provence.
Add the chopped onions and cook them down until they are soft and translucent – about 20 minutes.
Add the burgers and nestle them into the poaching liquid.
Cook burgers on one side until they are no longer pink – about 5 minutes – then flip.
Cook a few minutes more on the other side. Burgers should be around 140 degrees for medium rare.
Top each burger with a handful of grated Gruyere or other Swiss cheeses.
Toast the Brioche buns and spread with butter or a garlic aioli.
Put each burger with cheese onto a bun and top with a spoonful or two of the onion mixture.
