How to Make French Onion Funeral Potatoes
Follow these simple steps to prepare this delicious French Onion Funeral Potatoes:
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). While the oven warms up, grab your 9×13-inch baking dish and spray it with a little nonstick cooking spray.
Step 2: Combine the Potato Mixture
In a large mixing bowl, combine the thawed hash browns, melted butter, shredded cheddar cheese, and sour cream. Give it a good stir until all those creamy, cheesy elements are combined into a luscious mixture.
Step 3: Sauté the Onions
In a medium non-stick skillet over medium heat, melt the butter. Toss in the diced yellow onion and sauté until it softens up, about 3-5 minutes. Add the minced garlic and cook for an additional minute, allowing those flavors to meld beautifully.
Step 4: Create the Sauce
Sprinkle in the flour, kosher salt, black pepper, cayenne pepper, and dried mustard. Cook this mixture for another minute, stirring constantly. Gradually whisk in the milk and chicken broth until you get a thick, velvety sauce.
Step 5: Incorporate the Sauce with Potatoes
Pour the onion sauce into the potato mixture and give it everything you’ve got! Stir until every potato is coated in that cheesy, oniony goodness. Once well mixed, transfer the mixture into your prepped baking dish.
Step 6: Bake and Fry the Onions
Pop the casserole into the oven and bake for 45-50 minutes, or until it’s nice and bubbly. While that’s happening, heat the vegetable oil in a large saucepan over high heat until it reaches 350°F (175°C). Carefully add about 1 cup of the thinly sliced onions to the hot oil in batches and fry until they’re golden brown, then transfer them to a paper towel-lined baking sheet to drain excess oil. Don’t forget to sprinkle them with a little salt!
As soon as your casserole is done baking, pull it out and generously sprinkle those crispy fried onions over the top. Serve hot and watch everyone swoon over the deliciousness!
