French onion rice is like the side dish version of the soup, with sweet, jammy caramelized onions, a fabulous white wine infused beef broth, and fluffy rice finished with a generous sprinkle of gruyere cheese. It’s a dream!
In a large frying pan or Dutch oven, melt butter over medium-low heat.
3 tbsp butter
Add the onions, olive oil, and kosher salt. Stir occasionally until browned (25-30 minutes). Some of the onions might stick a bit, but keep gently stirring to dislodge them.
