- 2 Tbsp. olive oil
- 5 thinly sliced onions
- 1 ½ tsp. kosher salt
- Black pepper to taste
- 1 tsp. sugar

Caramelize the Onions
Start by melting the olive oil and 2 tablespoons of butter in a large skillet over low-medium heat. Add the sliced onions along with 1 teaspoon of salt, a dash of pepper, and the sugar. Stir everything together, cover the skillet, and let it sauté for 10 minutes.
After the initial cooking, uncover and increase the heat to medium. Continue to stir for another 10 minutes, allowing those fragrant onions to turn a lovely golden brown. Finally, add the thyme, sherry (or apple cider vinegar), and beef broth. This step is crucial to build flavor – cook until the liquid evaporates and your onions are perfectly caramelized, around 15 minutes more.

Create the Cheese Sauce
In a Dutch oven, melt the remaining 2 tablespoons of butter over medium heat. Stir in the flour and let it cook for about a minute. Then, whisk in the heavy cream and milk until smooth. Add the remaining ½ teaspoon of salt and nutmeg, letting it simmer until thickened (around 2-3 minutes). Finally, mix in all but ½ cup of the gruyère and Swiss cheese until wonderfully melted. Your cheese sauce is now ready, and trust me, it smells heavenly!
Slice the Potatoes
While your cheese sauce is thickening, slice the russet potatoes into ¼-inch thick rounds. This will ensure even cooking and a delightful texture in the final dish.
Assemble and Bake
Grease a 9-by-13-inch baking dish with butter. Begin layering by placing half of the sliced potatoes at the bottom, followed by half of your caramelized onions. Repeat with the remaining potatoes and onions. Top generously with the reserved gruyère, Swiss cheese, and a sprinkle of Parmesan, if desired.
Cover the dish with foil, making sure it doesn't touch the cheese. Bake in a preheated oven at 375˚F for 45-55 minutes, until the potatoes are tender. Then, remove the foil and let it bake for an additional 20-25 minutes until golden brown. After baking, let it sit for 20 minutes before serving; this allows the flavors to meld beautifully.
Your French Onion Potatoes au Gratin is now ready to be enjoyed – a comforting dish that’s sure to be a crowd-pleaser!
