Introduction
French Onion Funeral Potatoes are a rich, comforting casserole perfect for family gatherings or potlucks. This dish combines creamy potatoes, savory cheese, and crispy fried onions for a flavorful crowd-pleaser.

Ingredients
- 32 ounces frozen cubed hash browns, thawed
- ¼ cup (½ stick / 57 g) unsalted butter, melted
- 2 cups (226 g) sharp cheddar cheese, shredded
- 1 ½ cups (345 g) sour cream
- ¼ cup (½ stick / 57 g) unsalted butter
- 1 small yellow onion, diced
- 2 teaspoons garlic, minced
- ¼ cup (31 g) all-purpose flour
- 1 teaspoon kosher salt
- ½ teaspoon black pepper
- ½ teaspoon cayenne pepper
- ½ teaspoon dried mustard
- ½ cup (120 g) chicken broth, room temperature
- ½ cup (122.5 g) whole milk, room temperature
- 2 large yellow onions, thinly sliced, layers separated (about 4 cups)
- 4 cups (32 ounces) vegetable oil
- ½ teaspoon kosher salt
Instructions
- Step 1: Preheat the oven to 350°F. Spray a 9×13-inch baking dish with nonstick cooking spray.
- Step 2: In a large bowl, combine the thawed potatoes, melted butter, shredded cheddar cheese, and sour cream. Mix well and set aside.
- Step 3: Make the sauce. In a medium non-stick skillet over medium heat, melt ¼ cup butter. Add the diced onion and cook until softened, about 3-5 minutes. Add the minced garlic and cook for an additional minute.
- Step 4: Stir in the flour, kosher salt, black pepper, cayenne pepper, and dried mustard. Cook for one more minute while stirring.
- Step 5: Slowly whisk in the whole milk and chicken broth until the mixture is well combined. Continue cooking and whisking until the sauce thickens.
- Step 6: Pour the sauce into the potato mixture and mix thoroughly. Transfer the combined mixture into the prepared baking dish.
- Step 7: Bake the casserole for 45-50 minutes, or until bubbly and heated through.
- Step 8: While the casserole is baking, prepare the fried onions. Line a large baking sheet with two layers of paper towels and set aside.
- Step 9: Heat the vegetable oil in a large saucepan over high heat until it reaches 350°F.
- Step 10: Working in batches, carefully add about 1 cup of sliced onions to the hot oil. Fry, stirring occasionally, until the onions turn pale golden brown, about 2-5 minutes. Use a slotted spoon or fine mesh strainer to remove the onions and place them on the lined baking sheet. Repeat with remaining onions, ensuring oil temperature stays at 350°F.
- Step 11: Sprinkle the fried onions with kosher salt and toss to coat evenly.
- Step 12: When the casserole is done baking, remove it from the oven and evenly sprinkle the fried onions over the top.
- Step 13: Serve the casserole warm and enjoy.
Tips & Variations
- Use mild or sweet onions for frying if you prefer less sharpness in the topping.
- Substitute Greek yogurt for sour cream to add protein and reduce fat.
- Add chopped fresh herbs like thyme or parsley to the sauce for extra flavor.
- For a vegetarian version, replace chicken broth with vegetable broth.
- Use sharp or smoked cheddar to enhance the cheese flavor.
Storage
Store any leftover casserole covered in the refrigerator for up to 3 days. Reheat in the oven at 350°F until warmed through to maintain crispness on top. Fried onions are best added fresh before serving to stay crunchy; if storing separately, keep them in an airtight container at room temperature for up to 1 day.

FAQs
Can I use fresh potatoes instead of frozen hash browns?
Yes, you can use fresh potatoes peeled and diced similarly in size to frozen hash browns, but be sure to blanch them briefly to soften before using in the recipe.
How can I make the fried onions less oily?
Allow the fried onions to drain well on paper towels after frying and avoid overcrowding the pan, which causes the oil temperature to drop and results in greasier onions.

- 1 teaspoon kosher salt
- ½ teaspoon black pepper

- ½ cup (120 g) chicken broth, room temperature
- ½ cup (122.5 g) whole milk, room temperature
Fried Onions
- 2 large yellow onions, thinly sliced (about 4 cups, layers separated)
- 4 cups (32 ounces) vegetable oil
- ½ teaspoon kosher salt
Instructions
- Preheat Oven: Preheat your oven to 350°F (175°C) and spray a 9×13-inch baking dish with nonstick cooking spray to prepare for baking the casserole.
- Prepare Potato Mixture: In a large bowl, combine the thawed hash browns, melted butter, shredded sharp cheddar cheese, and sour cream. Mix well until evenly incorporated. Set aside while you prepare the sauce.
- Make the Sauce: In a medium non-stick skillet over medium heat, melt ¼ cup unsalted butter. Add the diced small yellow onion and sauté until softened, about 3-5 minutes. Add the minced garlic and cook for an additional 1 minute until fragrant.
- Add Dry Ingredients: Sprinkle in the flour, kosher salt, black pepper, cayenne pepper, and dried mustard. Stir and cook the mixture for about 1 minute to eliminate the raw flour taste.
- Add Liquids: Gradually whisk in the whole milk and chicken broth, continuing to cook and whisk until the sauce thickens and is smooth and creamy.
- Combine Sauce with Potatoes: Pour the thickened sauce into the bowl with the potato mixture. Stir thoroughly to combine all ingredients well. Transfer the entire mixture evenly into the prepared baking dish.
- Bake the Casserole: Place the dish in the preheated oven and bake for 45 to 50 minutes, or until the casserole is bubbly and heated through.
- Prepare Fried Onions: While the casserole bakes, line a large baking sheet with two layers of paper towels. In a large saucepan, heat vegetable oil over high heat until it reaches 350°F (175°C).
- Fry Onion Slices: Working in batches, carefully add about 1 cup of the thinly sliced onion layers to the hot oil. Stir occasionally and fry until the onions turn a pale golden brown, about 2 to 5 minutes. Using a slotted spoon or fine mesh strainer, remove the fried onions and place them in a single layer on the paper towel-lined baking sheet to drain excess oil. Repeat with remaining onions, ensuring the oil temperature remains at 350°F between batches.
- Season Fried Onions: Sprinkle the fried onions with ½ teaspoon kosher salt and toss gently to coat evenly.
- Top the Casserole and Serve: When the casserole has finished baking, remove it from the oven and immediately sprinkle the crispy fried onions over the top. Serve the dish warm for maximum flavor and texture.
Notes
- Use thawed hash browns to ensure even cooking and proper texture in the casserole.
- Keep the oil temperature steady at 350°F while frying onions to achieve optimal crispiness without burning.
- Adjust the cayenne pepper to taste if you prefer less or more heat.
- For a vegetarian version, substitute chicken broth with vegetable broth.
- The casserole can be prepared a day ahead; bake just before serving for best results.
