Instructions

1. Step 1: Preheat oven to 375°F. Boil 2 lbs peeled and diced russet potatoes in salted water for 15 minutes until tender. Drain and mash with 1/2 cup heavy cream, 1 tsp salt, and 1/2 tsp black pepper until smooth.
2. Step 2: In a skillet, melt 4 tbsp butter over medium heat. Add 2 thinly sliced yellow onions and 1 tsp fresh thyme leaves. Cook, stirring occasionally, for 20 minutes until onions are deeply golden and caramelized.
3. Step 3: Stir 2 tbsp all-purpose flour into the caramelized onions and cook for 1 minute, then fold the onion mixture into the mashed potatoes.
4. Step 4: Lightly grease a 9-inch pie dish. Spread half the mashed potato mixture evenly in the dish, then sprinkle 3/4 cup shredded aged Quebec cheddar cheese over it.
5. Step 5: Layer the remaining mashed potato mixture on top, smooth the surface, then sprinkle the remaining 3/4 cup cheese evenly over the top.
6. Step 6: Bake uncovered for 25-30 minutes until the cheese melts and forms a golden crust. Let rest 10 minutes before slicing and serving warm.
