Ingredients Notes

The magic of French Onion Stuffed Potatoes lies in its simple yet flavorful ingredients. Each one has an important role to play in bringing the dish together.

Start with large russet potatoes. Their starchy interior becomes perfectly fluffy when baked, and their sturdy skins hold up well to stuffing. If you prefer, Yukon Gold potatoes can work too, though their texture is creamier and slightly less firm.

The star of the filling is, of course, the onions. Yellow onions are ideal for caramelizing because they’re naturally sweet. Take your time cooking them down – their deep, golden color and rich flavor are key to replicating that classic French onion taste.

For the cheese, you’ll need a combination of Gruyère and Parmesan. Gruyère provides that nutty, melty goodness reminiscent of French onion soup, while Parmesan adds a sharp, salty bite. If Gruyère isn’t available, Swiss cheese makes an excellent substitute.

A splash of beef broth ties the filling together, adding depth and a subtle savory note. For a vegetarian option, swap this for vegetable broth – it’s just as delicious.

Finally, don’t forget the butter and a touch of thyme. Butter enhances the richness of the filling, while thyme adds a gentle herbaceous aroma that complements the onions perfectly.

How To Make French Onion Stuffed Potatoes

Creating these French Onion Stuffed Potatoes is a rewarding process, with each step building layers of flavor and texture. Let’s get started!

Begin by preheating your oven to 400°F (200°C). Scrub the potatoes thoroughly, then pierce them all over with a fork to allow steam to escape. Place the potatoes on a baking sheet and bake for 50–60 minutes, or until they’re tender when pierced with a knife.

While the potatoes bake, caramelize the onions. Heat a large skillet over medium heat and melt 2 tablespoons of butter. Add thinly sliced onions, a pinch of salt, and cook, stirring occasionally, for 30–40 minutes. They should become deeply golden and fragrant – patience is key!

Once the onions are caramelized, deglaze the pan with ¼ cup of beef broth. Stir to scrape up any browned bits from the bottom of the skillet, then sprinkle in a teaspoon of fresh thyme leaves. Cook for another 2 minutes, allowing the flavors to meld.

When the potatoes are done, let them cool slightly. Cut a slit down the top of each potato and gently scoop out the insides, leaving a thin shell. Mash the potato flesh in a bowl with a bit of butter, salt, and pepper, then stir in the caramelized onion mixture and half the grated Gruyère cheese.

Stuff the potato shells generously with the filling, then top with the remaining Gruyère and a sprinkle of Parmesan. Return the potatoes to the oven and bake for an additional 15 minutes, or until the cheese is melted and bubbling.

Serve hot, garnished with a sprinkle of fresh thyme or a drizzle of olive oil for an extra touch of elegance. These potatoes are ready to shine!

Storage Options

These French Onion Stuffed Potatoes store beautifully, making them a great option for meal prep or leftovers.

To refrigerate, place the stuffed potatoes in an airtight container and store for up to 3 days. Reheat in a 375°F (190°C) oven for 15–20 minutes, or until warmed through.

For longer storage, freeze the potatoes before the second bake. Wrap each one tightly in foil and place in a freezer-safe bag. When ready to enjoy, thaw in the refrigerator overnight, then bake as directed.

Avoid microwaving, as it can make the potato skins rubbery. The oven is your best bet for maintaining that perfect texture.

Variations and Substitutions

This recipe is highly adaptable, so feel free to get creative with the flavors and ingredients.

For a protein-packed version, add cooked, crumbled bacon or shredded rotisserie chicken to the filling. The smoky or savory notes will pair beautifully with the caramelized onions.

Prefer a vegetarian twist? Swap the beef broth for mushroom or vegetable broth and stir in sautéed mushrooms for an earthy depth.

If you’re a fan of spice, add a pinch of crushed red pepper flakes to the onions or a drizzle of hot sauce on top. It’s a bold twist that complements the creamy filling.

Experiment with cheese varieties. Cheddar, fontina, or even blue cheese can bring unique flavors to the dish. Mix and match to find your favorite combination.

Finally, try using sweet potatoes instead of russet potatoes for a sweeter, more nutrient-packed alternative. The caramelized onions and Gruyère will still shine, but with a different flavor profile.

Whether you’re serving these French Onion Stuffed Potatoes as a show-stopping side dish or a comforting main, they’re sure to become a favorite in your recipe collection. Don’t be afraid to put your own spin on them – the possibilities are endless. Enjoy!
