French Onion Funeral Potatoes Recipe

I made these French Onion Funeral Potatoes over the weekend, and they were the ultimate hit at our family dinner table. The combination of shredded hash browns baked in a rich, velvety sour cream and French onion cheese sauce, topped with crushed buttered French fried onions, is pure comfort food heaven.

I love how this recipe elevates a beloved classic potluck casserole by infusing deep, savory caramelized onion flavors throughout every single bite. It is warm, cheesy, and features an unbeatable crispy crunch on top.

Trust me, once you experience that bubbly, savory cheese pull paired with crunchy fried onions, this crowd-pleasing casserole will easily become your go-to side dish just like it did for me.

Ingredients

Using sour cream, French onion dip, and real Gruyère or Swiss cheese delivers that authentic, deeply savory French onion soup flavor profile.

• 1 bag (30 oz) frozen shredded hash brown potatoes, thawed (provides the hearty, potato casserole base)
• 1/2 cup unsalted butter, melted (divided for the potato sauce and crispy topping)
• 1 container (16 oz) sour cream (creates a rich, creamy baked texture)
• 1 container (8 oz) French onion dip (infuses bold, savory caramelized onion flavor throughout)
• 1 can (10.5 oz) condensed cream of chicken soup (or cream of mushroom for a vegetarian option)
• 1.5 cups shredded Gruyère, Swiss, or white cheddar cheese (melts into a silky, nutty cheese pull)
• 1 packet (1 oz) dry French onion soup mix (amplifies the rich, savory French onion taste)
• 1/2 teaspoon garlic powder (adds background aromatic warmth)
• 1/2 teaspoon freshly cracked black pepper (balances the rich, cheesy sauce)
• 2 cups French fried onions, coarsely crushed (delivers that iconic, golden crispy top)

Note: This recipe yields 10 to 12 hearty side-dish servings.

How to Make French Onion Funeral Potatoes?

Follow these simple, step-by-step instructions to turn shredded hash browns and French onion dip into a bubbly, cheesy casserole.

Mix the Potato Filling

Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish with non-stick spray. In a large bowl, combine 1/4 cup of the melted butter, sour cream, French onion dip, condensed soup, dry French onion soup mix, garlic powder, and black pepper, stirring until smooth. Fold in the shredded Gruyère or white cheddar cheese and the thawed hash brown potatoes until evenly coated.

Assemble and Bake

Spread the cheesy hash brown mixture evenly into your prepared 9×13-inch baking dish. Cover the dish loosely with aluminum foil and bake at 350°F (175°C) for 30 minutes until hot and bubbling around the edges.

Add Topping and Finish

While the casserole bakes, toss the crushed French fried onions with the remaining 1/4 cup of melted butter in a small bowl. Remove the foil from the baking dish, sprinkle the buttered French fried onions evenly across the top, and bake uncovered for an additional 12 to 15 minutes until the topping is deep golden brown and crunchy. Let rest for 5 minutes before serving.

Additional Tips for Making this Recipe Better

Here are a few personal tricks I rely on to ensure this potato casserole turns out thick, bubbly, and perfectly crunchy every time.

• I always make sure the hash browns are completely thawed and patted dry with paper towels so extra moisture doesn’t make the casserole watery.
• I highly recommend using a mix of French onion dip and dry soup mix because combining both creates an incredibly rich flavor depth without extra labor.
• I like to add the French fried onion topping during the last 15 minutes of baking so the onions get perfectly crisp without scorching or burning.

How to Serve French Onion Funeral Potatoes?

Scoop generous portions of the hot, bubbly casserole directly from the 9×13-inch dish onto dinner plates alongside your favorite entrees. Garnish with a sprinkle of freshly chopped chives or parsley for a bright pop of green against the golden onion topping. This savory casserole serves as the ultimate comfort side for holiday hams, roasted turkey, grilled steaks, pork chops, or Sunday potluck spreads.
