How to Make french onion scalloped potatoes

Step 1: Caramelize the Onions

Start by thinly slicing the yellow onions and cooking them slowly in butter over medium-low heat until they become golden brown and sweetly fragrant, about 25-30 minutes. This step builds the deep, rich flavor base that’s crucial for the dish.

Step 2: Prepare the Creamy Sauce

After the onions are caramelized, stir in flour to absorb the butter and onions’ moisture, then gradually whisk in milk and broth. Continue cooking until the sauce thickens smoothly. Season with garlic, thyme, salt, and pepper for layers of savory goodness.

Step 3: Slice the Potatoes

While the sauce comes together, peel and thinly slice your potatoes with a sharp knife or mandoline to ensure even cooking. Thin slices help the potatoes absorb the sauce flavor while baking uniformly.

Step 4: Assemble the Dish

Layer half the potatoes in a buttered baking dish, spread half the onion sauce evenly on top, then sprinkle with cheese. Repeat with the remaining potatoes, sauce, and finish with a generous cheese layer to achieve that golden, bubbly topping.

Step 5: Bake to Perfection

Cover the baking dish with foil and bake in a preheated oven at 350°F (175°C) for about 45 minutes. Remove the foil for the last 15 minutes to let the cheese brown beautifully while the potatoes become tender.

Pro Tips for Making french onion scalloped potatoes

• Use Uniform Potato Slices: Ensure even thickness for consistent cooking and texture.
• Low and Slow for Onions: Caramelize onions gently to avoid bitterness and develop sweetness.
• Don’t Skip the Sauce Thickening: Properly cook the roux base to prevent a runny or lumpy sauce.
• Rest Before Serving: Letting the dish sit for 10 minutes after baking helps it set and slice neatly.
• Fresh Herbs Matter: Adding herbs towards the end preserves their freshness and brightness.
