- 32 ounces frozen cubed hash browns (thawed)
- ¼ cup unsalted butter (melted)
- 2 cups sharp cheddar cheese (shredded)
- 1 ½ cups sour cream
- 1 small yellow onion (diced)
- 2 teaspoons garlic (minced)
- ¼ cup all-purpose flour
- 1 teaspoon kosher salt
- ½ teaspoon black pepper
- ½ teaspoon cayenne pepper

- ½ cup chicken broth
- ½ cup whole milk
- 2 large yellow onions (thinly sliced (about 4 cups))
- 4 cups vegetable oil (for frying)
- ½ teaspoon kosher salt
How to Make French Onion Funeral Potatoes Step-by-Step
- Step 1: Preheat your oven to 350°F. Spray a 9×13-inch baking dish with nonstick spray to ensure your casserole comes out easily.
- Step 2: Combine the thawed hash browns, melted butter, shredded cheddar cheese, and sour cream in a large bowl. Mix well to create a creamy potato base, then set aside.
- Step 3: Melt ¼ cup butter in a medium non-stick skillet over medium heat. This will form a delicious base for your caramelized onions.
- Step 4: Cook the diced onions for 3-5 minutes until softened. Add the minced garlic and cook for an additional minute, releasing wonderful aromas.
- Step 5: Stir in the flour, kosher salt, black pepper, cayenne pepper, and dried mustard. Cook this mixture for another minute to bloom the flavors beautifully.
- Step 6: Whisk in the milk and chicken broth slowly, stirring continually until well combined. Keep whisking until the sauce thickens and achieves a rich consistency.
- Step 7: Mix the thickened sauce into the potato mixture and stir until evenly combined. Pour the mixture into the prepared baking dish, spreading it evenly.
- Step 8: Bake for 45-50 minutes, or until the casserole is bubbly and heated through.
- Step 9: Prepare the fried onions while the casserole is baking. Line a large baking sheet with two layers of paper towels, setting aside to catch the excess oil later.
- Step 10: Heat the vegetable oil in a large saucepan over high heat to 350°F, perfect for frying your onions!
- Step 11: Fry about 1 cup of sliced onions in batches. Stir occasionally until they turn a pale golden brown, about 2-5 minutes.
- Step 12: Remove the fried onions using a fine mesh strainer or slotted spoon, and place them in an even layer on the lined baking sheet. Set aside to cool and repeat with the remaining onions.
- Step 13: Sprinkle the cooled fried onions with kosher salt, gently tossing to coat for extra flavor.
- Step 14: Top your baked casserole with the fried onions evenly over the surface right after taking it out from the oven.
- Step 15: Serve hot and enjoy the delightful blend of flavors and textures in every bite.
