6 servings
- 3 lb yellow onions (about 5 large), halved and thinly sliced
- 2 tbsp unsalted butter
Chef's tipUse a stick or block-style dairy-free butter - not a soft tub spread - and swap one-for-one. - 1 tbsp olive oil
- ½ tsp kosher salt, plus more to taste
- ¼ tsp black pepper
- 1 tbsp dry white wine or dry sherry (optional)
Instructions
- 1
Melt the butter with the olive oil in a large heavy-bottomed skillet or Dutch oven over medium heat until the butter is foamy and just beginning to subside.

Add all the sliced onions and the salt, then stir to coat them in the fat. The pan will be very full — this is expected.
