How to Make French Onion Funeral Potatoes Recipe

Step 1: Prepare Your Oven and Baking Dish

Start off by preheating your oven to 350°F and giving your 9×13-inch baking dish a good spray with nonstick cooking spray. This will ensure our cheesy masterpiece doesn’t stick and slides right onto your serving plate when baked.

Step 2: Mix the Potato Base

In a large bowl, combine the thawed cubed hash browns with melted butter, shredded sharp cheddar cheese, and sour cream. Mix everything thoroughly until the potatoes are luxuriously coated with cheese and cream. This mixture is the heart of your French Onion Funeral Potatoes Recipe, setting the stage for layers of flavor and texture.

Step 3: Craft the Savory French Onion Sauce

Heat butter in a medium non-stick skillet over medium heat, then add the diced yellow onion. Cook slowly until the onion softens (around 3-5 minutes), developing that sweet, mellow flavor. Add minced garlic and cook for another minute to release its aroma. Sprinkle in the flour, kosher salt, black pepper, cayenne, and dried mustard, stirring constantly to cook out the raw flour flavor. Gradually whisk in room temperature milk and chicken broth until the sauce thickens and turns silky smooth. This sauce is what makes this French Onion Funeral Potatoes Recipe sing with that irresistible French onion soup essence.

Step 4: Combine Sauce and Potatoes, Then Bake

Pour the finished sauce into the potato mixture and stir until fully incorporated. Transfer this creamy blend into your prepared baking dish and spread out evenly. Pop it into the oven and bake for 45-50 minutes until bubbling hot and perfectly golden on top.

Step 5: Prepare the Crispy Fried Onions

While the casserole bakes, it’s time for the crunchy finale. Heat vegetable oil in a large saucepan over high heat until it hits 350°F. Working in batches, drop thinly sliced onion layers into the hot oil and fry until they turn pale golden brown, about 2-5 minutes. Use a slotted spoon to carefully remove the onions and place them on paper towels to drain and crisp up. Sprinkle a little kosher salt over them while still hot to enhance their flavor.

Step 6: Finish with Fried Onions and Serve

Take the casserole from the oven and generously sprinkle the fried onions over the top. This final touch adds the quintessential crunch and that enchanting French onion aroma, completing your French Onion Funeral Potatoes Recipe with style and taste.

Make Ahead and Storage

Storing Leftovers

Store any leftover French Onion Funeral Potatoes Recipe in an airtight container in the refrigerator for up to 4 days. This allows the flavors to meld even more, making reheated portions just as delicious—if not better.

Freezing

You can freeze the casserole either before baking or after it’s fully cooked and cooled. Wrap it tightly in plastic wrap followed by foil to avoid freezer burn. It will keep well for up to 2 months. Thaw overnight in the fridge before reheating.

Reheating

Reheat leftovers covered with foil in a 350°F oven for about 20-25 minutes or until warmed through. To keep the fried onions crisp, add fresh fried onions on top after reheating.

FAQs

Can I use fresh potatoes instead of frozen hash browns?

Absolutely! You can dice fresh potatoes and parboil them before mixing with the sauce. Just ensure they are tender but hold their shape well in the casserole.

Is there a vegetarian version of this French Onion Funeral Potatoes Recipe?

Yes, simply swap the chicken broth for vegetable broth. The dish will still have plenty of rich, savory flavor from the onions and cheese.

Can I use a different type of cheese instead of sharp cheddar?

Sharp cheddar is classic here for its flavor and melting quality, but you could try Gruyère or a mild mozzarella for a different cheesy twist.

You can use store-bought fried onions to save time, but homemade crispy fried onions give a fresher, more flavorful crunch that really elevates the French Onion Funeral Potatoes Recipe.

How spicy is this recipe with cayenne pepper included?

The cayenne is used sparingly to add a subtle warmth and depth without making the dish spicy. If you’re sensitive to heat, you can reduce or omit it without losing the overall flavor balance.
