Burger and Potato Casserole

Instructions:

1. Preheat the oven to 180°C (350°F).
2. Prepare the potatoes:
   Peel and thinly slice the potatoes. Set aside.
3. Cook the hamburgers:
   In a frying pan, lightly cook the hamburger patties until browned on both sides (they don’t need to be fully cooked, as they will finish in the oven). Set aside.
4. Sauté onions and garlic:
   In the same pan, sauté the chopped onions and garlic until soft and fragrant. You can add a splash of olive oil if needed.
5. Layer the casserole:
   Grease a large casserole dish with olive oil or butter. Layer the bottom of the dish with half of the sliced potatoes. Add the cooked hamburger patties on top, followed by the sautéed onions and garlic. Cover with the remaining potatoes.
6. Prepare the sauce:
   In a bowl, whisk together the heavy cream, milk, salt, and pepper. Pour this mixture evenly over the casserole.
7. Top with cheese:
   Sprinkle the grated cheese on top of the potatoes.
8. Bake:
   Place the dish in the preheated oven and bake for about 40-45 minutes, or until the potatoes are tender, the cheese is melted, and the top is golden brown.
9. Garnish and serve:
   Remove from the oven and let it rest for a few minutes. Garnish with fresh herbs like parsley or thyme before serving.
