Ingredients

• 4 large russet potatoes
• 4 tablespoons unsalted butter
• 4 medium yellow onions, halved longitudinally and finely sliced
• 1/2 teaspoon dried thyme leaves
• 1/2 cup dry sherry or alternative dry white wine
• 1 cup beef broth
• 2 cups Gruyere cheese, grated
• Kosher salt and freshly ground black pepper, as required

Instructions

1. Preheat the oven to 375°F. Start by preparing the potatoes. Clean the russet potatoes thoroughly, scrubbing away any dirt. Using a fork, pierce each potato a few times to allow steam to escape during baking. Place the potatoes directly on the oven rack or on a baking sheet. Bake the potatoes for about 45-60 minutes, or until they are tender when pierced with a fork. You can also test their doneness by gently squeezing the potatoes; they should give slightly. Once they are baked, remove them from the oven and set them aside to cool slightly while you prepare the other ingredients.
2. Caramelize the onions: While the potatoes bake, it’s time to make the star of the dish—the caramelized onions. Heat the butter in a large skillet over medium-high heat. Once the butter has melted, add the finely sliced onions. Season the onions with kosher salt, freshly ground black pepper, and dried thyme leaves. Stir occasionally to ensure even cooking. As the onions cook, they will gradually soften and turn a beautiful golden-brown color. This process takes time, so be patient. The goal is to caramelize the onions slowly to bring out their natural sweetness. This can take anywhere from 15 to 20 minutes. Stir the onions occasionally to prevent them from burning and ensure they cook evenly.
3. Deglaze the pan and reduce the liquid: Once the onions are caramelized and beautifully golden, it’s time to add some depth of flavor. Pour the dry sherry (or white wine) into the pan to deglaze it. The wine will loosen any flavorful bits stuck to the bottom of the skillet, adding richness to the mixture. Stir the wine into the onions, allowing it to cook for a minute or two. Then, pour in the beef broth and bring the mixture to a simmer. Let the liquid reduce for about 5 to 10 minutes, allowing the flavors to concentrate. The goal is to have a slightly thickened, rich onion mixture. Once the liquid has reduced, remove the pan from the heat and set it aside.
4. Prepare the potato filling: Once the baked potatoes are cool enough to handle, slice off the top third of each potato. Be careful not to cut too much—leave enough potato flesh in the bottom to support the filling. Using a spoon, scoop out the insides of the potato, placing the flesh into a medium-sized bowl. Be sure to leave a thin layer of potato inside the skin to maintain its structure. Mash the potato flesh with a fork or potato masher until it’s smooth, but with some texture remaining. This creates a creamy base for the onion mixture to be incorporated into.
5. Combine the mashed potato with the onion mixture: Add half of the caramelized onion mixture to the mashed potato flesh. Stir everything together, making sure the onions are evenly distributed throughout the potatoes. The onions will infuse the potatoes with their sweet, savory flavors, while the broth and wine reduction will add a touch of richness. Taste the mixture and adjust the seasoning with kosher salt and freshly ground black pepper as needed. If you want a slightly more complex flavor, you can also add a pinch of fresh herbs like rosemary or parsley at this stage.
6. Stuff the potatoes: Carefully spoon the mashed potato and onion mixture back into the hollowed-out potato skins. Pack the filling in gently to ensure it’s evenly distributed, but be careful not to crush the skins. Once all the potatoes are filled, top each one with the remaining onion mixture, spreading it evenly across the top of each potato.
7. Add the cheese: The Gruyere cheese is what takes these stuffed potatoes from delicious to irresistible. Sprinkle a generous amount of grated Gruyere on top of each stuffed potato. The cheese will melt and form a golden, bubbling layer that adds both flavor and texture. If you want to take it a step further, consider adding a little extra cheese for an even cheesier topping.
8. Bake the stuffed potatoes: Place the filled potatoes on a baking sheet and transfer them to the preheated oven. Bake for about 10 to 15 minutes, or until the Gruyere cheese has melted and turned golden brown. If you prefer a slightly more crispy top, you can switch the oven to broil for the last 1-2 minutes of cooking. Keep a close eye on the potatoes while broiling to ensure the cheese doesn’t burn.
9. Serve and enjoy: Once the potatoes are perfectly baked and the cheese has formed a deliciously golden crust, remove them from the oven. Serve them while hot, and enjoy the comforting combination of creamy potato, sweet caramelized onions, and nutty Gruyere cheese. These French Onion Stuffed Potatoes are sure to be a crowd-pleaser, whether you’re serving them as a main course or as an accompaniment to your favorite roasted meats.

Tips and Variations

• Substitutions: If you don’t have Gruyere cheese on hand, you can easily substitute it with Swiss cheese, fontina, or even cheddar for a different flavor profile. Each of these cheeses melts beautifully and will still complement the caramelized onions perfectly.
• Vegetarian option: To make this dish vegetarian, simply swap out the beef broth for vegetable broth. This will still provide a rich base for the caramelized onions, and the Gruyere cheese will deliver the creamy, indulgent finish you crave.
• Extra toppings: If you’re looking to add a bit of extra flair, consider adding crispy bacon crumbles on top of the potatoes before baking. The salty, smoky bacon pairs wonderfully with the rich onion filling. Alternatively, sautéed mushrooms or even a sprinkle of crispy fried onions can be added for added texture and flavor.
• Make ahead: This recipe can easily be made ahead of time for busy nights or dinner parties. Prepare the potatoes and fill them with the mashed potato-onion mixture, then refrigerate them until you’re ready to bake. When you’re ready to serve, simply top with the Gruyere cheese and bake as directed.
