Follow these easy steps to make the best French Onion Cheesy Potatoes:

  1. Preheat the oven to 190°C (375°F). Grease a 9×13-inch (23×33 cm) baking dish with butter or cooking spray.
  2. Sauté the onions: In a large skillet, melt butter over medium heat. Add sliced onions and cook for 8–10 minutes, stirring occasionally, until golden brown and caramelized. Add garlic and cook for 1 more minute.
  3. Prepare the creamy mixture: In a large bowl, combine cream of mushroom soup, sour cream, French onion soup mix, black pepper, and half of the cheddar cheese. Stir until smooth.
  4. Layer the potatoes: Spread half of the sliced potatoes in the baking dish. Top with half of the caramelized onion mixture and half of the creamy mixture. Repeat layers with remaining potatoes, onions, and cream mixture.
  5. Add cheese topping: Sprinkle the remaining cheddar cheese over the top, followed by mozzarella cheese. Finish with crushed crackers or breadcrumbs for extra crunch.
  6. Bake uncovered for 50–60 minutes, or until the potatoes are tender and the top is golden and bubbly.
  7. Rest and serve: Let the dish rest for 10 minutes before serving. This helps the sauce thicken and makes it easier to slice.
