Ingredients Notes

The beauty of French Onion Stuffed Potatoes is that they use simple, flavorful ingredients that come together beautifully. Here’s what you’ll need:

• Russet Potatoes – The perfect choice for baking! Their fluffy interior holds up well to the rich onion filling.
• Yellow Onions – You can’t have French onion flavor without sweet, golden caramelized onions. Yellow onions are best, but white or sweet onions work too.
• Butter – Helps caramelize the onions and adds rich flavor. Use unsalted butter so you can control the saltiness.
• Beef Broth – Adds depth and that signature French onion soup taste. For a vegetarian version, swap in mushroom or vegetable broth.
• Worcestershire Sauce – A secret ingredient that enhances the umami flavor of the onions.
• Thyme – Fresh or dried thyme brings a subtle herbal note that balances the richness.
• Gruyère Cheese – This classic French cheese is known for its nutty, melty goodness, making it the best choice for this dish. If needed, you can substitute with Swiss or provolone.
• Parmesan Cheese – Adds an extra layer of salty, umami-rich flavor to the topping.
• Salt & Pepper – Essential for seasoning both the onions and the potatoes.
• Olive Oil – Helps crisp up the potato skins for an irresistible texture.

Special Equipment

• A baking sheet for roasting the potatoes
• A large skillet for caramelizing the onions
• A potato masher or fork to mix the filling

How to Make French Onion Stuffed Potatoes

Making these French Onion Stuffed Potatoes is easier than you might think. Here’s how to bring them to life:

Step 1: Bake the Potatoes

Preheat your oven to 400°F (200°C). Scrub your russet potatoes, then prick them all over with a fork to allow steam to escape. Rub them with olive oil and salt, then place them directly on the oven rack or a baking sheet. Bake for 45-60 minutes until fork-tender.

Step 2: Caramelize the Onions

While the potatoes bake, thinly slice your onions and heat a large skillet over medium-low heat. Add butter and onions, then cook slowly for 30-40 minutes, stirring occasionally, until they turn deep golden brown.

Once caramelized, stir in Worcestershire sauce, thyme, and beef broth. Let it simmer for a few minutes until most of the liquid is absorbed. Season with salt and pepper and set aside.

Step 3: Scoop and Mix

Once the potatoes are cool enough to handle, cut them in half lengthwise. Scoop out the flesh, leaving a small border to keep the skins intact. Place the scooped-out potato in a bowl and mash it with a bit of butter, salt, and pepper. Stir in half of the caramelized onions and some shredded Gruyère cheese.

Step 4: Stuff and Bake Again

Spoon the mixture back into the potato skins, piling it high. Top each potato with the remaining caramelized onions and extra Gruyère cheese. Place the stuffed potatoes back in the oven for 10-15 minutes, or until the cheese is melted and bubbly.

Step 5: Finish and Serve

Remove from the oven and sprinkle with grated Parmesan and a bit more fresh thyme. Serve hot and enjoy every cheesy, oniony bite!

Storage Options

These French Onion Stuffed Potatoes store well, making them great for meal prep!

• Refrigerate: Store leftovers in an airtight container for up to 4 days.
• Freeze: Wrap each stuffed potato individually in foil and place them in a freezer-safe bag. They’ll last for up to 3 months.
• Reheat: Warm in a 350°F oven for 15-20 minutes or microwave in 30-second intervals until heated through.

Variations and Substitutions

This recipe is super versatile! Here are some fun ways to switch things up:

• Make It Vegetarian: Swap beef broth for vegetable broth and skip the Worcestershire sauce (or use a vegetarian alternative).
• Try a Different Cheese: While Gruyère is classic, you can use Swiss, provolone, white cheddar, or even mozzarella.
• Add Protein: For a heartier meal, mix in some shredded rotisserie chicken, cooked bacon, or crumbled sausage.
• Use Sweet Potatoes: For a unique twist, try using sweet potatoes instead of russet potatoes! The caramelized onions pair beautifully with their natural sweetness.
• Make It a Casserole: Instead of stuffing individual potatoes, mix everything together and bake in a casserole dish topped with extra cheese.
