How to Make French Onion Scalloped Potatoes

Step 1: Caramelize the Onions

Begin by thinly slicing yellow onions and cooking them slowly in butter over low heat until they turn golden brown, soft, and fragrant, which usually takes about 30-40 minutes. This step is critical—it transforms the raw sharpness of onions into a sweet, rich base that defines the dish’s flavor.

Step 2: Prepare the Potatoes

While the onions are caramelizing, peel and thinly slice Yukon Gold potatoes using a mandoline or a sharp knife. Uniform slices ensure they cook evenly and absorb the creamy sauce perfectly.

Step 3: Make the Cream Sauce

In a saucepan, gently warm heavy cream with minced garlic, fresh thyme, salt, and pepper. This mixture will soak into the layered potatoes and onions, creating a smooth and flavorful sauce that ties the whole dish together.

Step 4: Layer the Ingredients

In a buttered baking dish, layer half of the potato slices, then spread half of the caramelized onions on top, sprinkle some cheddar cheese, and pour a portion of the cream sauce over. Repeat with the remaining potatoes, onions, cheese, and cream, ensuring each layer is evenly distributed.

Step 5: Bake Until Golden and Bubbly

Cover the dish with foil and bake at 350°F (175°C) for about 45 minutes. Remove the foil and continue baking for an additional 20 minutes or until the top is golden brown, bubbly, and the potatoes are tender when pierced with a fork.

Pro Tips for Making french onion scalloped potatoes

• Slice Potatoes Uniformly: Use a mandoline for even cooking and professional presentation.
• Don’t Rush Onions: Low and slow caramelization is key to unlocking their sweet flavor.
• Use Room Temperature Ingredients: This helps everything cook more evenly and smoothly blend.
• Let It Rest: Allow your dish to sit for 10 minutes after baking for easier slicing and better texture.
• Cover with Foil Initially: Prevents the top from burning before the potatoes cook all the way through.

How to Serve french onion scalloped potatoes

Garnishes

Sprinkle fresh thyme leaves or chopped parsley on top for a pop of color and fresh aroma that brightens the rich layers beneath. A light drizzle of olive oil or a few grates of fresh Parmesan can also elevate the presentation and flavor.

Side Dishes

These potatoes pair beautifully with roasted meats like beef, chicken, or pork and a crisp green salad or steamed vegetables to balance the richness. They also make a hearty side for vegetarian mains like mushroom Wellington or grilled portobello mushrooms.

Creative Ways to Present

Serve french onion scalloped potatoes in individual ramekins for a charming single-serving option, or transform the leftovers into a crispy casserole topping by adding breadcrumbs and broiling briefly for extra texture.

Make Ahead and Storage

Storing Leftovers

Place any leftovers in an airtight container and refrigerate promptly. The flavors will deepen overnight, making for an even tastier meal the next day.

Freezing

This dish freezes well for up to 2 months. Cool completely, cover tightly with foil or plastic wrap, and freeze. Defrost overnight in the fridge before reheating to maintain its creamy texture.

Reheating

Reheat in a 350°F oven covered with foil to prevent drying out. Remove the foil for the last 10 minutes to crisp the top. Avoid microwaving to keep the creamy layers intact and avoid sogginess.

FAQs

Can I use other types of potatoes?

Yes, but Yukon Gold is ideal because of its creamy texture and ability to hold shape. Russets can work but may become mushy, while red potatoes are firmer and less creamy.

How do I know when the onions are properly caramelized?

They should be a deep golden brown color with a sweet aroma, soft texture, and no raw bite. Patience is essential since rushing will cause burning or uneven cooking.

Can I prepare french onion scalloped potatoes in advance?

Absolutely. You can assemble the dish a day before baking. Keep it covered in the refrigerator and bake as directed when ready to serve.

Is there a way to make this dish lighter?

To reduce calories, swap heavy cream for half-and-half or milk, and use a moderate amount of cheese. Keep in mind, this may affect the richness and thickness slightly.

What type of cheese works best?

Sharp cheddar provides a classic bold flavor, but Gruyère or Swiss cheese add great nuttiness and melt beautifully for a French-inspired twist.
