Pro Tips for Cheesy French Onion Potatoes Casserole

To make the most of your French Onion Funeral Potatoes, take the time to fry your own onions for a truly irresistible topping. The homemade crispy onions add a delightful crunch and fresh flavor that store-bought versions can’t match, elevating the dish to a whole new level of deliciousness.

If you prefer to use fresh potatoes instead of frozen hash browns, simply peel, cube, and lightly boil them for 5-7 minutes before incorporating them into the casserole. This option allows for a more customized texture and flavor in your dish, giving you the flexibility to tailor it to your preferences.

For versatile meal planning, assemble the casserole up to 24 hours in advance without the fried onions. Refrigerate tightly covered, and when ready to bake, allow it to come to room temperature for 30 minutes before placing it in the oven. You can also freeze the unbaked casserole for up to 3 months for longer storage. Thaw completely in the refrigerator before baking, ensuring a convenient and delicious meal prep option for any occasion.

How to Make Cheesy French Onion Potatoes Casserole

Step 1: Preheat Oven and Prepare Baking Dish

Preheat oven to 350°F and coat a 9×13-inch baking dish with nonstick spray.

Step 2: Prepare Potato Mixture

Combine thawed hash browns, melted butter, shredded cheese, and sour cream in a large bowl. Mix thoroughly and set aside.

Step 3: Make Sauce

1. Melt butter in a medium non-stick skillet over medium heat. Add diced onion and cook until softened (3-5 minutes). Add minced garlic and cook for 1 minute. Stir in flour, salt, black pepper, cayenne pepper, and dried mustard, cooking for another minute. Slowly whisk in milk and chicken broth. Cook and whisk continuously until thickened.

Step 4: Combine Potato Mixture and Sauce

Pour the sauce into the potato mixture and mix well. Transfer the mixture to the baking dish.

Step 5: Bake Casserole

Place the casserole in the preheated oven and bake for 45-50 minutes, until bubbly and heated through.

Step 6: Prepare Fried Onions

Prepare a large baking sheet by lining it with two layers of paper towels. Heat vegetable oil in a large saucepan over high heat until it reaches 350°F. Fry sliced onions in batches, adding about 1 cup at a time, until pale golden brown (2-5 minutes). Use a slotted spoon or fine mesh strainer to transfer the fried onions to the prepared baking sheet. Repeat with remaining onions, ensuring oil is at 350°F for each batch. Sprinkle fried onions with kosher salt and toss to coat.

Step 7: Top Casserole and Serve

Once the casserole has baked for 45-50 minutes, take it out of the oven. Sprinkle fried onions evenly on top of the hot casserole and serve promptly.

Storage Tips

Once you have prepared and enjoyed your French Onion Funeral Potatoes, storing any leftovers properly is essential to maintain their delicious flavors and textures. Place the remaining casserole in an airtight container and store it in the refrigerator for up to 4 days. To reheat the dish while preserving its contrasting textures, bake it in a preheated 350°F oven for 15-20 minutes. Cover the dish with foil for the first 10 minutes to prevent excessive browning, then remove the foil to re-crisp the onion topping for a satisfying meal.

For those looking to make French Onion Funeral Potatoes ahead of time, you have the option to assemble the casserole without the fried onions up to 24 hours before baking. Cover the dish tightly with plastic wrap and refrigerate it until you are ready to bake. Allow the casserole to come to room temperature for about 30 minutes before placing it in the oven, ensuring even cooking throughout. If you prefer to freeze the unbaked casserole for longer storage, it can be kept in the freezer for up to 3 months. Thaw the frozen dish completely in the refrigerator overnight before baking it according to the original recipe instructions.

Ingredient Substitutions

If you prefer using fresh potatoes instead of frozen hash browns, you can certainly do so. Simply peel, cube, and lightly boil the potatoes for 5-7 minutes before incorporating them into the casserole. This will ensure they cook evenly and have a tender texture in the finished dish.

While sharp cheddar cheese is recommended for its bold flavor, feel free to experiment with other cheeses that melt well, such as mozzarella or Gouda. Mixing different types of cheese can add depth and complexity to the cheesy sauce in the casserole.

For a lighter version of the recipe, you can substitute sour cream with plain Greek yogurt. Greek yogurt provides a similar creamy texture and tanginess, making it a suitable alternative for those looking to reduce the calorie content or add a slightly different flavor profile to the dish.

Serving Suggestions

For a fun twist on serving French Onion Funeral Potatoes, consider portioning the casserole into individual ramekins before baking. This not only creates a charming presentation at the table but also ensures each guest gets their fair share of the crispy onion topping. Garnish each ramekin with a sprig of fresh thyme for a touch of elegance before serving.

To elevate the flavors of this dish, pair it with a tangy cranberry-orange relish on the side. The bright acidity and sweetness of the relish will cut through the richness of the cheesy potatoes, creating a well-balanced and satisfying holiday meal. The combination of savory French Onion Funeral Potatoes with the zesty relish is sure to impress your guests and leave them craving more.
