Instructions
- Bake the Potatoes
- Preheat your oven to 400°F (200°C) and lightly grease a large baking sheet.
- Scrub the potatoes clean, pat them dry, and prick each one several times with a fork.
- Place the potatoes on the prepared baking sheet and bake for 55–60 minutes, or until tender when pierced with a fork.
- Remove from the oven and set aside to cool slightly. Keep the oven on for the final bake.
- Caramelize the Onions
- While the potatoes bake, heat the olive oil and butter in a large skillet over medium heat.
- Add the sliced onions and cook slowly, stirring often, until they turn a deep golden brown — about 20 minutes.
- This step develops the rich, sweet flavor that defines French onion–style dishes.
- Sauté the Mushrooms
- Add the sliced mushrooms to the skillet with the onions and continue cooking for 6–8 minutes, stirring occasionally, until the mushrooms are tender and lightly browned.
- Stir in the minced thyme and cook for another minute to release the herb’s aroma.
- Build the Savory Filling
- Pour in the beef broth and scrape up any browned bits from the pan using a wooden spoon.
- Let the mixture simmer for 3–5 minutes, until the broth reduces slightly and forms a glossy coating on the onions and mushrooms.
- Season generously with salt and freshly ground black pepper to taste.
- Remove from heat and let the filling cool slightly while preparing the potatoes.
- Prepare and Fill the Potatoes
- Once the baked potatoes are cool enough to handle, carefully slice each one lengthwise down the center.
- Use a fork to gently fluff the insides and create space for the filling.
- Spoon the warm onion-and-mushroom mixture evenly into each potato.
- Top with Cheese and Bake
- Sprinkle the tops generously with shredded Swiss or Gruyère cheese.
- Return the filled potatoes to the oven and bake for 15–20 minutes, or until the cheese is melted and the filling is bubbling.
- For a beautifully browned top, broil for 2–3 minutes, watching closely until the cheese turns golden and slightly crisp.
- Cool and Serve
- Let the potatoes rest for about 5 minutes before serving.
- Enjoy these savory French onion and mushroom stuffed potatoes warm, paired with a fresh salad or roasted vegetables for a complete meal.
- Tips for the Best Flavor
- Substitute beef broth with mushroom broth for an extra earthy taste.
- Add a pinch of garlic powder or fresh minced garlic while cooking the onions for deeper flavor.
- To save time, caramelize the onions and mushrooms in advance — they’ll keep in the fridge for up to 3 days.
