French onion funeral potatoes are the ultimate comfort food for family gatherings potlucks or holiday tables rich cheesy and loaded with savory flavor thanks to real caramelized onions and crispy homemade fried onion topping this recipe transforms simple ingredients into a celebration-worthy dish your guests will remember

One year I brought these to Thanksgiving and they vanished before the main course was even on the table now everyone insists I handle potatoes for every big meal and these are always the star

Ingredients

  • Frozen cubed hash browns: thawed makes prep effortless and ensures even cooking frozen brands vary in potato size go for smaller cubes if possible
  • Unsalted butter: both for richness and for adjusting salt I always use fresh butter for best flavor
  • Sharp cheddar cheese: shredded brings a tangy gooey melt choose a block and shred yourself for optimal melt and taste
  • Sour cream: for creamy tang and to keep the casserole soft and not dry pick full fat for richness
  • Yellow onions: real onions are the backbone for the sauce and topping try for firm ones with tight skins
  • Garlic: fresh minced offers a punch of flavor and depth
  • All purpose flour: thickens the sauce and gives silky body to the casserole use unbleached for best texture
  • Kosher salt: ensures layers of seasoning I taste as I go
  • Black pepper and cayenne: for slight heat
  • Dried mustard: brightens and cuts through the richness
  • Chicken broth and whole milk: both create a cream sauce with just enough body make sure they are room temp to avoid curdling
  • Vegetable oil: for frying the onions avoid olive oil here you want something neutral
  • Choose onions that are firm and glossy: older or sprouting onions can turn bitter when fried

Instructions

Prepare The Baking Dish:
Lightly spray a nine by thirteen inch baking dish so the casserole releases easily later
Mix The Potatoes:
In a large mixing bowl stir together thawed hash browns melted butter shredded cheddar and sour cream until every potato piece is coated

Bake The Casserole:
Place the dish in the preheated oven bake forty five to fifty minutes until the edges are bubbling and the center is hot
Fry The Onions:
Line a baking sheet with two layers of paper towels to drain the onions after frying In a large saucepan heat vegetable oil until a thermometer shows three hundred fifty degrees or a tiny bread cube sizzles instantly Drop thinly sliced onions in batches so the oil stays hot fry each batch two to five minutes stirring gently until just golden and crisp With a slotted spoon remove onions and spread onto prepared towels sprinkle immediately with kosher salt Repeat in batches always letting oil return to temperature between rounds

Let the casserole cool completely before storing Cover tightly or move to an airtight container and refrigerate up to four days Reheat covered in the oven to restore crispness if needed pop it under the broiler for a few minutes to revive the fried onions on top

Instructions

Step 01

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

Step 02

In a large bowl, mix thawed hash brown potatoes, melted butter, shredded sharp cheddar cheese, and sour cream until fully combined. Set aside.

Step 03

In a medium nonstick skillet over medium heat, melt butter. Add diced onion and sauté until softened, about 3–5 minutes. Stir in minced garlic and cook for 1 additional minute. Sprinkle in flour, salt, black pepper, cayenne pepper, and dried mustard. Cook, stirring constantly, for 1 minute.

Step 04

Slowly pour in whole milk and chicken broth while whisking continuously. Continue whisking over medium heat until the mixture thickens and is smooth.

Step 05

Pour the prepared sauce over the potato mixture. Stir well to ensure even distribution.

Step 06

Spread the potato and sauce mixture evenly into the prepared baking dish. Bake at 350°F for 45–50 minutes, until hot and bubbly.

Step 07

Line a large baking sheet with two layers of paper towels. Set aside for draining fried onions.

Step 08

Add vegetable oil to a large saucepan and heat over high until oil reaches 350°F.

Step 09

Working in small groups, carefully lower about 1 cup of sliced onions at a time into the hot oil. Fry, stirring gently, for 2–5 minutes or until onions turn light golden brown.

Step 10

Using a slotted spoon or fine mesh strainer, remove fried onions and spread in a single layer on the prepared baking sheet. Immediately sprinkle with kosher salt, tossing gently to coat. Repeat frying and draining with remaining onions, ensuring oil returns to temperature between each batch.

Step 11

Once the casserole is baked through, remove from oven. Evenly distribute fried onions over the hot casserole and serve immediately.
