Introduction
Funeral Potatoes, also known as Au Gratin Hash Brown Casserole, is a comforting and cheesy dish perfect for gatherings or a cozy family meal. This creamy, crunchy casserole combines tender hash browns with a rich cheese sauce and a buttery cornflake topping for the ultimate comfort food experience.

Ingredients
- 1 (30 oz) package frozen shredded hash brown potatoes, thawed
- 4 Tbsp butter, diced into 1 Tbsp pieces
- 1/2 cup finely chopped yellow onion
- 3 Tbsp all-purpose flour
- 3 cups milk (whole or 2%)
- 2 cups shredded sharp cheddar cheese
- 1/2 cup finely shredded parmesan cheese
- 1 cup sour cream
- Salt and black pepper, to taste
- 4 cups cornflakes, crushed (about 2 cups once crushed)
- 3 Tbsp butter, melted
- 1 1/2 Tbsp chopped fresh parsley
Instructions
- Step 1: Preheat your oven to 350 degrees Fahrenheit.
- Step 2: In a large saucepan over medium heat, melt 4 tablespoons of butter. Add the chopped onion and sauté until softened, about 5 to 6 minutes.
- Step 3: Stir in the flour and cook, stirring constantly, for 1 minute. Gradually whisk in the milk and continue stirring until the mixture lightly simmers and thickens.
- Step 4: Remove the sauce from heat. Stir in the cheddar and parmesan cheeses until melted and smooth.
- Step 5: Mix in the sour cream and season the sauce with salt and black pepper to taste, aiming for a slightly salty flavor to season the potatoes well.
- Step 6: Place the thawed hash browns in a large mixing bowl. Pour the cheese sauce over them and toss gently to coat evenly. Transfer the mixture to a 13 by 9-inch baking dish and spread into an even layer. No need to grease the dish.
- Step 7: In a separate bowl, combine the crushed cornflakes with the melted butter, tossing until evenly coated.
- Step 8: Sprinkle the buttered cornflake topping evenly over the casserole.
- Step 9: Bake in the preheated oven for 40 to 50 minutes, until the casserole is hot throughout and the topping is golden and crispy. Garnish with chopped fresh parsley and serve warm.
Tips & Variations
- For extra flavor, try adding cooked and crumbled bacon or diced ham to the potato mixture before baking.
- Substitute crushed Ritz crackers or panko breadcrumbs for the cornflake topping if you prefer a different crunch.
- Use low-fat sour cream and reduced-fat cheese to lighten up the dish without sacrificing too much creaminess.
- Make this casserole a day ahead, keep it covered in the fridge, then bake just before serving.
Storage
Store leftover casserole covered in the refrigerator for up to 3 days. To reheat, warm individual portions in the microwave or reheat the entire casserole in a 350-degree oven until heated through, about 15-20 minutes. Adding a little extra shredded cheese on top before reheating can boost flavor and moisture.

FAQs
Can I use fresh potatoes instead of frozen hash browns?
While fresh potatoes can be used, shredded potatoes should be par-cooked and drained well before using to avoid excess moisture in the casserole.
Is it necessary to thaw the frozen hash browns?
Yes, thawing the hash browns helps them absorb the sauce evenly and prevents excess moisture from making the casserole soggy.

- Fresh parsley adds a subtle fresh flavor and a nice visual contrast.
- For a vegetarian version, ensure the cheeses and sour cream are vegetarian-friendly.
