How to Make Ground Beef And Onion Gratin

  1. Preheat oven to 350°F (175°C).
  2. Grease a 2-quart baking dish.
  3. Heat 1 tablespoon of olive oil in a large skillet over medium-high heat.
  4. Brown 1 pound of ground beef with 2 cloves of minced garlic. Drain off any excess grease.
  5. Stir in 1/4 cup of grated Parmesan cheese and set aside.
  6. In a saucepan, bring 2 cups of water to a boil. Add 2 medium yellow onions, thinly sliced. Simmer for 10 minutes until softened.
  7. Drain the onions, reserving 1/2 cup of the cooking liquid.
  8. In a bowl, combine the reserved onion liquid, 10.75 oz can cream of celery soup (or cream of mushroom/chicken), 1 teaspoon dry mustard, 1/2 teaspoon salt, 1/4 teaspoon black pepper, 1 cup shredded cheddar cheese, and 2 green onions, thinly sliced.
  9. Mix well and add the browned ground beef.
  10. Pour the mixture into the prepared baking dish.
  11. Bake for 25 minutes.
  12. While the gratin bakes, prepare the topping: In a separate bowl, combine 1 cup grated Parmesan cheese, 1/2 cup bread crumbs, and 2 tablespoons melted butter.
  13. Mix well until evenly combined.
  14. Remove the baking dish from the oven and sprinkle the crumb/cheese mixture evenly over the top.
  15. Broil for 2-3 minutes, or until golden brown and bubbly. Watch carefully to prevent burning.
