Funeral potatoes made from scratch — a homemade cheddar sauce with frozen shredded hash browns and a crunchy sour cream and onion chip topping, baked until bubbly. No canned soup required.
Melt butter in a large stockpot over medium heat. Cook onion until soft, about 5 minutes. Stir in flour and cook 1 minute more.
Whisk in chicken broth and half and half. Season with salt, thyme, and pepper. Cook over medium-high heat, whisking constantly, until bubbly. Reduce heat and simmer 4 minutes until thickened. Remove from heat and stir in shredded cheddar until melted.
Stir in frozen hash browns and return to medium heat. Cook about 10 minutes until thawed and combined. Remove from heat and stir in sour cream.
Preheat oven to 350°F and grease a 9x13 baking dish. Pour in potato mixture and spread evenly. Top with crushed potato chips.
Bake uncovered for 45–50 minutes until hot and bubbly. Let stand 5 minutes before serving.
Notes
Kept frozen hash browns work best — if your bag has ice chunks, thaw and drain first
Don't add chip topping until right before baking if making ahead
Freshly shredded cheddar melts more smoothly than pre-bagged
