Ingredients for French Onion Stuffed Potatoes

• Russet Potatoes: Starchy and perfect for baking, they achieve a light, fluffy texture when cooked. Their size works well for slicing and layering.
• Unsalted Butter: Allows for better control over the salt levels in the dish, providing richness and helping to caramelize the onions to a golden brown.
• Yellow Onions: Offer a mild, sweet flavor when caramelized, adding depth to the dish. Thin slicing ensures even cooking.
• Dried Thyme Leaves: Adds an earthy, aromatic flavor that complements the onions and potatoes. Fresh thyme can also be used as a substitute, using a bit more if fresh.
• Dry Sherry or Alternative Dry White Wine: Enhances the dish with a nutty, complex flavor. If unavailable, a dry white wine like Sauvignon Blanc or Chardonnay can work well.
• Beef Broth: Provides a savory, umami taste, enhancing the flavor profile. Opt for a low-sodium version if available to better control the saltiness.
• Gruyere Cheese: Melts beautifully, adding a nutty and slightly sweet flavor. Swiss cheese can be used as an alternative if Gruyere is unavailable.
• Kosher Salt and Freshly Ground Black Pepper: Essential for seasoning. Kosher salt is preferred for its texture, and freshly ground black pepper adds a hint of spice. Adjust based on the overall taste of the dish.

How To Make This French Onion Stuffed Potatoes

First Step: Preheat the oven to 375°F.

Second Step: In a large skillet, melt the unsalted butter over medium-high heat. Once melted, add the finely sliced onions. Season with kosher salt, freshly ground black pepper, and dried thyme leaves. Cook until the onions are soft and caramelized, stirring occasionally to ensure even cooking.

Third Step: Add the dry sherry or white wine to deglaze the pan, scraping up the flavorful bits from the bottom. Add the beef broth and bring the mixture to a gentle boil. Continue cooking until the liquid has reduced significantly, about 5-10 minutes.

Fourth Step: Meanwhile, cut off the top third of each baked russet potato and carefully scoop out the inner flesh into a medium-sized bowl. Add half of the onion mixture and mix until well combined.

Fifth Step: Fill each potato shell with the potato-onion mixture and arrange them on a baking tray. Top each with the remaining onion mixture and a generous amount of grated Gruyere cheese.

Sixth Step: Place the baking tray in the preheated oven and bake until the Gruyere cheese has melted and is golden brown. For extra browning, broil for about 1 minute.

Seventh Step: Remove from the oven and serve the potatoes while warm.

Prep Time: 15 minutes minutes

Cook Time: 30 minutes minutes

Servings: 4

Ingredients

• 6 russet potatoes
• 1 ½ teaspoons olive oil
• 1 teaspoon coarse salt
• 2 yellow onions approximately 1.5 pounds/600 grams
• 2 tablespoons olive oil
• ½ teaspoon kosher salt
• ¼ teaspoon ground black pepper
• ½ teaspoon thyme leaves from 3 long stems
• ½ cup water
• ¼ cup white wine
• ¼ cup unsalted butter 4 tablespoons/2 ounces
• 1 teaspoon kosher salt
• ¼ teaspoon ground black pepper
• ⅓ cup sour cream 2.7 ounces/75 grams
• ½ cup heavy cream 118 ml
• 2 cups Gruyere cheese shredded (6 ounces/168 grams)
• 2 tablespoons chopped chives

Instructions

• Preheat the Oven
• Preheat your oven to 425°F (220°C).
• Prepare the Potatoes
• Scrub the potatoes under running water to remove any dirt. Prick each potato about 10 times all around with a fork.
• Rub the potatoes with 1 ½ teaspoons of olive oil and sprinkle them with 1 teaspoon of coarse salt. Arrange them on a baking sheet and bake in the oven for 1 hour, or until they’re soft when squeezed. Let the potatoes cool for about 25 minutes.
• Caramelize the Onions
• While the potatoes are baking, prepare the onions. Slice the onions thinly from root to stem.
• In a sauté pan over medium heat, add 2 tablespoons of olive oil. Once the oil is hot, add the sliced onions. Season with salt and pepper.
• Stir occasionally to prevent sticking. Allow the onions to caramelize slowly to avoid burning.
• After about 15 minutes, the onions will release liquid, forming a brown residue (fond) at the bottom of the pan. Add ¼ cup of water to deglaze, scraping the fond off the pan.
• Continue cooking for another 10 minutes, and deglaze again if needed.
• Five minutes after the final deglazing, add the thyme leaves and ¼ cup of white wine. Scrape up any remaining fond. The onions should be a translucent brown. Remove the pan from heat and set aside.
• Prepare the Twice-Baked Potatoes
• Reduce the oven temperature to 400°F (200°C).
• Once the potatoes have cooled for about 25 minutes, cut off the top third of each potato. Scoop out the insides into a bowl (a grapefruit spoon works well for this), and mash or rice them.
• Add the unsalted butter, kosher salt, ground black pepper, sour cream, heavy cream, and 1 cup of shredded Gruyere cheese to the bowl. Mix until smooth and creamy.
• Carefully spoon the mixture back into the potato shells. Top with ½ cup of Gruyere cheese. Place the potatoes back on the baking sheet and bake for 30 minutes.
• Finish and Serve
• After 30 minutes, remove the potatoes from the oven. Top each with the caramelized onions, then sprinkle the remaining ½ cup of shredded Gruyere on top.
• Place the baking sheet under the broiler until the cheese is bubbly and golden brown.
• Garnish with chopped chives and serve hot.
