Crispy French Onion Scalloped Potato Casserole Recipe

Ingredients You’ll Need

To make a delicious Crispy French Onion Scalloped Potato Casserole, gather the following ingredients:

• 4 large russet potatoes, peeled and thinly sliced
• 1 large onion, thinly sliced
• 2 cups heavy cream
• 1 cup grated Gruyère cheese
• 1 cup shredded mozzarella cheese
• 1 cup crispy fried onions
• 3 tablespoons unsalted butter
• 2 cloves garlic, minced
• 1 teaspoon dried thyme
• Salt and pepper to taste
• Fresh parsley for garnish (optional)

Step-by-Step Instructions

Follow these simple steps to create your Crispy French Onion Scalloped Potato Casserole:

1. Prepare the Potatoes

   Start by preheating your oven to 375°F (190°C). Peel the russet potatoes and slice them thinly, about 1/8 inch thick. You can use a mandoline for uniform slices, which helps ensure even cooking.

2. Sauté the Onions

   In a large skillet, melt 2 tablespoons of butter over medium heat. Add the thinly sliced onions and a pinch of salt. Sauté the onions for about 15-20 minutes, stirring occasionally, until they become soft and caramelized. Add the minced garlic and thyme for the last minute of cooking, then remove from heat.

3. Prepare the Cream Mixture

   In a medium bowl, whisk together the heavy cream, salt, and pepper. If you want to enhance the flavor, consider adding a pinch of nutmeg or a splash of Worcestershire sauce to the cream mixture.

4. Layer the Ingredients

   In a greased 9×13 inch baking dish, start layering the ingredients. Begin with a layer of sliced potatoes, followed by half of the sautéed onions. Pour a portion of the cream mixture over the onions and sprinkle with a layer of Gruyère cheese. Repeat the layers until all ingredients are used, finishing with a layer of potatoes and the remaining cream mixture on top.

5. Top with Cheese and Fried Onions

   Sprinkle the shredded mozzarella cheese on top of the final layer of potatoes. Then, add a generous amount of crispy fried onions for that crunchy topping that makes this casserole stand out.

6. Bake the Casserole

   Cover the baking dish with aluminum foil and bake in the preheated oven for 45 minutes. After 45 minutes, remove the foil and continue baking for an additional 15-20 minutes, or until the top is golden brown and the potatoes are tender when pierced with a fork.

7. Let it Rest

   Once out of the oven, let the casserole rest for about 10 minutes before serving. This helps the layers set and makes it easier to serve.
