Ingredients You’ll Need
For the Potatoes:

• 2 lbs Yukon Gold or Russet potatoes, thinly sliced
• 2 tbsp olive oil or butter
• 2 large yellow onions, thinly sliced
• 1 tsp sugar (helps with caramelization)
• ½ tsp salt
• ¼ tsp black pepper
• 1 tsp fresh thyme leaves (or ½ tsp dried thyme)
• 2 cloves garlic, minced
• 1 cup low-sodium beef or vegetable broth
• 1 tbsp Worcestershire sauce
• 1 ½ cups shredded Swiss or Gruyère cheese
• ¼ cup grated Parmesan cheese
• 1 tbsp chopped fresh parsley (for garnish)

Tools You’ll Need

• Large skillet or sauté pan
• 9×13-inch baking dish
• Sharp knife or mandoline
• Mixing bowl
• Foil (for baking cover)

Step-by-Step Instructions

Step 1: Caramelize the Onions
Heat olive oil or butter in a large skillet over medium-low heat.
Add sliced onions and sugar, then cook slowly for 20–25 minutes, stirring often.
Once golden brown and soft, stir in garlic and thyme and cook for 1 more minute.
Set aside and preheat your oven to 375°F (190°C).

Step 2: Slice the Potatoes
Wash and peel the potatoes, then slice them thinly (about ⅛ inch thick) using a knife or mandoline.
Try to keep the slices uniform for even baking.

Step 3: Layer the Dish
Grease a 9×13-inch baking dish.
Layer half of the sliced potatoes evenly in the dish.
Top with half of the caramelized onions and a sprinkle of Swiss cheese.
Repeat with the remaining potatoes, onions, and more cheese.

Step 4: Add the Broth Mixture
In a small bowl, mix the broth and Worcestershire sauce.
Pour the mixture evenly over the layered potatoes.
Top everything with the remaining Swiss cheese and sprinkle with grated Parmesan.

Step 5: Bake Covered
Cover the baking dish with foil and bake in the preheated oven for 40 minutes.
This allows the potatoes to steam and soften.

Step 6: Bake Uncovered
Remove the foil and bake for another 15–20 minutes, or until the cheese is bubbly and golden brown.
Insert a knife to check if the potatoes are tender.

Step 7: Rest & Garnish
Let the dish rest for 10 minutes to set before serving.
Sprinkle with chopped fresh parsley for color and flavor.

Tips for Perfect French Onion Potatoes
Take Time for Onions – Low and slow caramelizing is key to developing rich, sweet flavor.
Uniform Slices – Even thickness ensures even cooking.
Choose the Right Cheese – Gruyère melts beautifully and adds classic French onion flavor.
Don’t Rush – Letting the dish rest before serving improves texture and flavor.
Use Broth Wisely – It adds moisture and richness, so don’t skip it.

Serving Suggestions
Perfect Pair – Serve with roast chicken, grilled steak, or baked fish.
Holiday Favorite – Makes an excellent side dish for Thanksgiving or Christmas.
Light Salad – Pair with a crisp green salad with vinaigrette to balance the richness.
Leftover Magic – Enjoy reheated the next day as a savory breakfast with a fried egg on top.

Frequently Asked Questions

1. Can I make this ahead of time?
Yes! Assemble the dish up to a day in advance and refrigerate. Bake just before serving.

Mozzarella, provolone, or even sharp white cheddar work well if you don’t have Gruyère.
