Step‑by‑Step Instructions for French Onion Scalloped Potatoes
Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). While the oven warms up, prepare a 9×13-inch baking dish by greasing it lightly with butter. This will prevent the French Onion Scalloped Potatoes from sticking and ensure a beautifully golden crust.
Step 2: Slice the Onions
Next, thinly slice the sweet onions, aiming for about a quarter-inch thickness. In a large skillet over medium heat, add a tablespoon of butter and cook the onions until they are soft and caramelized, about 10-15 minutes. Stir occasionally to prevent burning, until they have turned a beautiful golden brown.
Step 3: Slice the Potatoes
While the onions are caramelizing, peel and slice the Russet potatoes into thin, even rounds—about an eighth-inch thick. This ensures they cook uniformly. Using a sharp knife or a mandoline can help achieve consistent slices, which is essential for perfect French Onion Scalloped Potatoes.
Step 4: Prepare the Sauce
In a medium saucepan, combine heavy cream, vegetable broth, minced garlic, fresh thyme, salt, and black pepper. Heat the mixture over medium heat until it begins to simmer. Stir often for about 5 minutes, allowing the flavors to meld together while preparing for the layering of the dish.
Step 5: Layer the Potatoes and Onions
Start layering the French Onion Scalloped Potatoes by placing a single layer of potato slices at the bottom of the greased baking dish. Follow this with half of the caramelized onions, and then pour a third of the cream sauce over the top. Repeat this process, finishing with a final layer of potatoes, onions, and sauce.
Step 6: Add Cheese and Bake
Sprinkle the Gruyère cheese and Parmesan on top of the final layer for that perfect cheesy crust. Cover the baking dish with aluminum foil and place it into the preheated oven. Bake for 40 minutes until the potatoes are tender and the flavors are well combined.
Step 7: Uncover and Brown
After 40 minutes, remove the foil and bake for an additional 15-20 minutes. This will allow the top to become golden brown and crispy. Keep an eye on it to avoid burning, and look for a bubbling, creamy texture that signals your French Onion Scalloped Potatoes are ready to be taken out of the oven.
Step 8: Cool and Serve
Once baked to perfection, remove the dish from the oven and let it rest for about 10 minutes. This resting time allows the layers to set and makes serving easier. Serve your French Onion Scalloped Potatoes warm, and enjoy the delightful flavors with your Thanksgiving feast!
Make Ahead Options
These French Onion Scalloped Potatoes are perfect for meal prep enthusiasts! You can slice the potatoes and caramelize the onions up to 24 hours in advance, storing them in an airtight container in the refrigerator to maintain freshness. The creamy sauce can also be prepared ahead and refrigerated for up to 3 days; just give it a quick stir before layering. When ready to serve, simply layer the prepped ingredients, add the cheese, cover, and bake as directed. This approach not only saves time but also ensures your dish is just as delicious when reheated—allowing you to focus on enjoying your Thanksgiving gathering!
