Ingredients

For the Potatoes

4 medium russet potatoes
1 tablespoon olive oil
1 tablespoon unsalted butter

For the Filling

1 large sweet onion, thinly sliced
1/4 cup dry white apple vinegar
1 tablespoon minced fresh thyme
1 cup beef broth
Salt and pepper to taste

For Topping

1-1/2 cups shredded swiss or gruyere cheese

How to Make French Onion Baked Potatoes

Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C). Lightly grease a large baking sheet. Place the russet potatoes on the baking sheet and prick them several times with a fork to allow steam to escape.

Step 2: Bake the Potatoes

Bake the potatoes at 400°F for 55-60 minutes until they are tender when pierced with a fork. Remove them from the oven and cool slightly while keeping it on.

Step 3: Make the Filling

In a large skillet or Dutch oven over medium heat:
1. Melt olive oil and butter together.
2. Add the thinly sliced onions.
3. Stir occasionally until they achieve a deep caramelized color, which should take about 20 minutes.

Step 4: Deglaze the Pan

Once the onions are caramelized:
1. Add dry white apple vinegar to deglaze the pan.
2. Scrape up any browned bits using a wooden spoon.
3. Stir in minced thyme and beef broth.
4. Bring this mixture to a simmer over medium heat, allowing it to cook for 3-5 minutes until slightly reduced.
5. Season with salt and pepper to taste.

Step 5: Prepare the Potatoes for Filling

After cooling slightly:
1. Use a knife to slice each potato down the middle.
2. Fluff up the insides gently with a fork.

Step 6: Stuff the Potatoes

Fill each potato generously with the French onion soup filling you prepared earlier. Top each one with shredded cheese.

Step 7: Bake Until Golden Brown

Return stuffed potatoes to the oven:
1. Bake at 400°F for an additional 15-20 minutes until filling is bubbly and cheese is melted.
2. Optionally, broil for an extra 2-3 minutes if you’d like your cheese browned.

Allow your French onion baked potatoes to cool for several minutes before serving warm. Enjoy!

How to Perfect French Onion Baked Potatoes

Choose Quality Potatoes: Select medium russet potatoes as they have the right balance of starch and moisture for baking.
Caramelize Onions Slowly: Take your time while caramelizing onions; low and slow yields the best flavor.
Use Homemade Broth: For even better taste, use homemade beef broth instead of store-bought for the filling.
Experiment with Cheeses: Try different cheeses like mozzarella or cheddar for unique flavors on top of your baked potatoes.
Don’t Skip Seasoning: Ensure you season well with salt and pepper throughout the cooking process for enhanced flavor.
Broil at the End: Broil the potatoes for a few minutes after baking to achieve a perfectly golden cheese topping.

Best Side Dishes for French Onion Baked Potatoes

Coleslaw: A tangy coleslaw adds crunch and balances out the rich flavors of French onion baked potatoes.

Common Mistakes to Avoid

When making French onion baked potatoes, it’s easy to make a few common errors that can affect the final dish. Here are some mistakes to avoid to ensure your baked potatoes turn out perfectly.

Overcooking the Potatoes: If you bake the potatoes for too long, they can become dry and mushy. Keep an eye on them and test for tenderness around 55 minutes.
Neglecting to Prick the Potatoes: Failing to prick the potatoes can cause them to burst while baking. Always use a fork to create several holes before cooking.
Using Low-Quality Cheese: Not all cheeses melt well. Use high-quality Swiss or Gruyere cheese for that perfect gooey topping.
Skimping on Seasoning: Under-seasoning your filling can lead to bland flavors. Taste and adjust salt and pepper as needed during cooking.
Not Letting the Potatoes Cool Before Handling: Trying to fill hot potatoes can lead to burns. Allow them to cool slightly after baking for easier handling.
