Ingredients for French Onion Stuffed Potatoes

• 4 large russet potatoes
• 4 tablespoons unsalted butter
• 4 medium yellow onions, halved and thinly sliced
• 1/2 teaspoon dried thyme leaves
• 1/2 cup dry sherry or a dry white wine alternative
• 1 cup beef broth (or vegetable broth for a vegetarian option)
• 2 cups Gruyère cheese, grated
• Kosher salt and freshly ground black pepper, to taste

Optional substitutions

• Substitute Gruyère with sharp cheddar, Swiss, or Fontina to suit your taste.
• Use vegetable broth instead of beef broth for a vegetarian version.
• Replace dry sherry with apple cider vinegar or omit it and add extra broth for a non-alcohol option.

How to Make French Onion Stuffed Potatoes – Step by Step

Step 1: Prepare the potatoes

Preheat the oven to 375°F (190°C). Bake the russet potatoes directly on the oven rack or on a baking sheet for about 45 minutes, or until a fork pierces cleanly and the interior is tender.

Step 2: Caramelize the onions

While the potatoes bake, melt the butter in a large skillet over medium heat. Add the sliced onions, thyme, and a pinch of salt and pepper. Stir occasionally and cook slowly until the onions reach a deep golden-brown color and develop sweet, rich flavor—about 25–30 minutes. Don’t rush this step; slow caramelization is key.

Step 3: Deglaze and finish the onions

When the onions are caramelized, add the dry sherry or white wine to deglaze the pan, scraping up browned bits from the bottom. Simmer for 5–10 minutes until the liquid has mostly reduced, then add the beef broth and simmer a few more minutes to concentrate the flavor.

Step 4: Hollow out the potatoes

Cut off the top third of each baked potato and carefully scoop out the flesh into a mixing bowl, leaving a sturdy shell. Mash the potato flesh and stir in about half of the caramelized onions until well combined; season with salt and pepper to taste.

Step 5: Stuff and bake

Spoon the mashed potato and onion mixture back into the potato shells. Top each filled potato with the remaining caramelized onions and a generous layer of grated Gruyère. Place the stuffed potatoes on a baking tray.

Step 6: Final bake

Bake in the preheated oven for 10–15 minutes, until the cheese has melted and is bubbling. For a golden, slightly crisp top, broil for 1–2 minutes—watch closely so the cheese doesn’t burn.

Step 7: Serve warm

Garnish with fresh thyme or chives if desired and serve immediately. These stuffed potatoes pair well with a crisp green salad to balance the richness.

Helpful tips

• Mix onions for complexity: Add sweet or red onions alongside yellow onions for extra depth of flavor.
• Be patient with caramelization: Low and slow heat yields deeply flavored, sweet onions—don’t try to speed this process with higher heat.
• Try different cheeses: Gruyère is classic for a French onion profile, but Swiss, Fontina, or even Parmesan sprinkled on top can change the character deliciously.
• Choose the right potato: Russets are ideal because they bake fluffy and hold up well when hollowed and stuffed.
• Broil with care: Cheese can brown quickly under the broiler—1–2 minutes is usually enough.

Serving suggestions

• Serve with a crisp green salad and a light vinaigrette to cut through the richness.
• Pair with a glass of dry white wine, such as Sauvignon Blanc or Chardonnay, which complements the savory, oniony flavors.
• Garnish with fresh thyme or chopped chives for color and a subtle herbal lift.
