Ingredients Notes

The beauty of this recipe lies in its simplicity, but the quality of each ingredient plays a vital role in creating the best possible dish.

Start with large russet potatoes. Their starchy, fluffy interior makes them ideal for baking and stuffing. Look for potatoes that are firm, evenly sized, and free of blemishes.

Next, you'll need yellow or sweet onions for caramelizing. These types of onions become beautifully golden and sweet when cooked low and slow. Don’t rush this step – it’s where much of the dish’s flavor comes from.

For the cheesy topping, Gruyère cheese is a must. Its nutty, melty goodness is reminiscent of traditional French onion soup. If Gruyère isn’t available, Swiss cheese makes a good substitute.

A splash of beef broth enhances the onion filling, adding depth and richness. If you’re keeping it vegetarian, feel free to substitute with vegetable broth.

Finally, a sprinkle of fresh thyme ties all the flavors together. It adds an earthy freshness that balances the richness of the dish.

How To Make French Onion Stuffed Potatoes

Creating these French Onion Stuffed Potatoes is easier than you might think. Let’s break it down step by step.

Start by baking your potatoes. Preheat your oven to 400°F (200°C) and scrub the potatoes clean. Pierce each one with a fork a few times, then bake them directly on the oven rack for about 45 minutes, or until tender when pierced with a knife.

While the potatoes bake, caramelize the onions. Thinly slice the onions and cook them over low heat in a large skillet with butter and olive oil. Stir occasionally, allowing them to slowly soften and develop a deep golden-brown color – this can take 20-25 minutes. Add a splash of beef broth toward the end to deglaze the pan and infuse the onions with extra flavor.

Once the potatoes are done, let them cool slightly before cutting a lengthwise slit across the top. Carefully scoop out the fluffy insides, leaving a thin layer to support the skin. Place the scooped potato in a mixing bowl.

Combine the mashed potato with the caramelized onions, shredded Gruyère cheese, a little more broth, and a pinch of thyme. Mix until creamy and well combined, then spoon the filling back into the potato skins, piling it high.

Top each stuffed potato with a little extra cheese and return them to the oven. Bake for another 10-15 minutes, or until the cheese is melted and bubbly.

Storage Options

If you have leftovers (though it’s unlikely!), these stuffed potatoes store beautifully.

Refrigerate them in an airtight container for up to 3 days. To reheat, place them on a baking sheet and warm in a 375°F (190°C) oven until heated through.

For longer storage, wrap each potato individually in plastic wrap and freeze for up to 2 months. Thaw overnight in the fridge before reheating as described above.

Variations and Substitutions

This recipe is endlessly adaptable to suit your preferences or dietary needs.

Cheese options: Swap out Gruyère for cheddar, mozzarella, or even a spicy pepper jack for a different flavor profile.
Add protein: Stir in cooked bacon, shredded chicken, or crumbled sausage to turn these potatoes into a complete meal.
Go veggie: Use vegetable broth and add sautéed mushrooms or spinach for a hearty vegetarian option.
Make it spicy: Add a dash of cayenne pepper or red chili flakes to the onion filling for a little heat.
Miniature versions: Use baby potatoes for bite-sized appetizers perfect for parties and gatherings.

The possibilities are endless, so don’t be afraid to get creative and make this recipe your own.

Now that you’ve got the full rundown, it’s time to experience the comfort and elegance of French Onion Stuffed Potatoes in your own kitchen. Whether it’s for a family dinner or a special occasion, this dish is sure to impress and delight!
