How to Make French Onion Funeral Potatoes

Preheat the Oven: Begin by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking dish with nonstick spray to ensure your casserole doesn't stick.
Combine Potato Ingredients: In a large mixing bowl, combine the thawed hash browns, melted butter, shredded sharp cheddar cheese, and sour cream. Mix everything well until the ingredients are evenly distributed, then set aside.
Prepare the Sauce: In a medium non-stick skillet over medium heat, melt the second portion of butter. Once melted, add the diced yellow onion and sauté for about 3-5 minutes until softened and translucent.
Add Garlic: Stir in the minced garlic and cook for another minute, until fragrant. This step enhances the savory depth of your sauce.
Make the Roux: Add the all-purpose flour, kosher salt, black pepper, cayenne pepper, and dried mustard to the skillet. Stir the mixture continuously for about 1 minute, allowing the roux to cook through.
Thicken the Sauce: Gradually whisk in the whole milk and chicken broth. Continue cooking while whisking constantly until the sauce thickens and achieves a smooth, creamy consistency.
Mix Sauce with Potatoes: Pour the hot sauce over the potato mixture, and gently stir until everything is evenly coated and combined.
Transfer to Baking Dish: Spread the potato mixture into the greased baking dish, smoothing it out so it’s evenly distributed.
Bake the Casserole: Place the baking dish in the preheated oven and bake uncovered for 45-50 minutes, or until the casserole is bubbly and heated through.
Fry the Onions: While the casserole is baking, heat vegetable oil in a large saucepan to 350°F (175°C). Carefully fry the thinly sliced large yellow onions in batches, about 1 cup at a time, stirring occasionally for 2-5 minutes, until the onions turn a pale golden brown.
Drain and Season: Using a slotted spoon, remove the fried onions and let them drain on paper towels lined on a baking sheet. Sprinkle with kosher salt immediately and toss lightly to coat. Repeat until all onions are fried.
Top and Serve: Once the casserole has finished baking, remove it from the oven and evenly sprinkle the crispy fried onions on top. Serve immediately to enjoy the best texture.

Optional: For added freshness, garnish with chopped parsley before serving.
