Step-by-step preparation of French Onion Potatoes au Gratin
Creating French Onion Potatoes au Gratin is a delightful culinary adventure that bridges comfort food with gourmet flair. Follow this step-by-step guide to prepare a creamy, cheesy dish that will impress your friends and family!
Preheat and prepare your baking dish
Start by preheating your oven to 375°F (190°C). Next, grab a 9-by-13-inch baking dish and generously butter the inside to ensure easy removal of the finished dish. This is a crucial step—nobody wants to struggle with sticking potatoes! You can even use a bit of olive oil if you want a different flavor. Just imagine the ooey-gooey goodness waiting to happen!
Caramelize the onions to perfection
The magic really begins with the onions. In a large skillet over medium-low heat, combine 2 tablespoons of olive oil and 2 tablespoons of salted butter. Once melted, add 5 thinly sliced onions, sprinkle with 1½ teaspoons of kosher salt, a few grinds of black pepper, and 1 teaspoon of sugar. Stir everything together, cover, and let it cook for around 10 minutes. This process is key to achieving that deep, golden caramelization. After the initial cooking, uncover the skillet and increase the heat to medium, stirring for an additional 10 minutes.
Once you see those onions turning a rich caramel hue, stir in 1 tablespoon of chopped fresh thyme, ¼ cup of dry sherry, and ½ cup of low-sodium beef broth. Cook until the liquid evaporates and the onions are perfectly caramelized—this should take about 15 more minutes. The aroma wafting through your kitchen will be mouthwatering!
Create the creamy sauce
In a Dutch oven, melt the remaining 2 tablespoons of butter over medium heat. Sprinkle in 2 tablespoons of all-purpose flour, stirring for about 1 minute to create a roux. Then, carefully whisk in 1½ cups of heavy cream and 1½ cups of whole milk. Add the remaining ½ teaspoon of salt and ¼ teaspoon of freshly grated nutmeg and bring it to a simmer. Keep whisking until your sauce thickens, which usually takes 2 to 3 minutes. Stir in all but ½ cup each of the gruyère and Swiss cheese until melted. Finally, fold in your caramelized onions and potato slices, letting all the flavors meld beautifully.
Layer the ingredients in your dish
Now it's time to bring your French Onion Potatoes au Gratin together! Layer half of the potato mixture into your buttered baking dish, followed by half of the caramelized onion mix. Then, repeat the layers with the remaining ingredients. Top everything off with the reserved gruyère, Swiss, and a sprinkling of ¼ cup grated parmesan cheese for that extra touch of flavor.
Bake until golden and bubbly
Cover your baking dish with foil, tenting it so it doesn’t touch the cheese, and place it in the preheated oven. Bake for 45 to 55 minutes until the potatoes are tender. Afterward, uncover and continue baking for another 20 to 25 minutes until the top is a beautiful golden brown. Once it’s out of the oven, let your dish sit for about 20 minutes before serving. For the finishing touch, sprinkle with fresh chives.

Add some greens for a twist
