Ingredients
4small onions(about 4.5 cups), sliced thin
3tablespoonsextra virgin olive oil
½teaspoonkosher salt
1cuplow-sodium beef broth
6sprigsfresh thymeplus more for serving
½loaf crusty French breadsliced into ½” thick slices
Heat a large nonstick skillet over medium-high heat. When warm, pour in the olive oil.
When the olive oil is shimmering, add the thinly sliced onions to the pan. Season with salt, and stir continuously with a wooden spoon.
Let the onions caramelize slowly, constantly stirring so the onions don’t burn on the bottom of the pan. This process should take 20-30 minutes, depending on the heat in your pan.
When the onions have browned beautifully, add the beef broth a quarter cup at a time. Stir with the spoon as the onions soak up the broth. Do this three more times. Add the thyme leaves, and remove the pan from the heat.
When the onions are cooked through, turn the oven on to its broil setting. Line a baking sheet with a nonstick baking mat or parchment paper, then set aside.
As the oven preheats, slice the bread. Place the sliced bread onto the prepared baking sheet.
Spoon the onions evenly on top of the sliced bread.
Lay down half a Swiss cheese slice, then top with shredded mozzarella. (There’s no exact amount here – eyeball it!)
Transfer the baking sheet to the oven, and broil for 4-6 minutes, or until the cheese has browned and is bubbling.
Remove from the oven, and let cool for 5-10 minutes.
