  • 1 tbsp melted butter (optional, for topping)
  • 1 tbsp olive oil

Instructions:

  1. Preheat the oven: to 375°F (190°C). Grease a 9x13-inch casserole dish.

  2. Cook the mushrooms and onions:

    • In a large skillet, heat the olive oil over medium heat.
    • Add the chopped onion and garlic, sautéing until softened (about 2-3 minutes).
    • Add the sliced mushrooms, season with salt, pepper, thyme, and paprika if using, and cook until the mushrooms are tender and golden (about 5-7 minutes). Set aside.
  3. Prepare the creamy sauce:

    • In a large bowl, combine the cream of mushroom soup, sour cream, and milk. Stir until smooth.
    • Mix in half of the shredded cheddar cheese and half of the grated Parmesan cheese.
  4. Layer the casserole:

    • Arrange half of the sliced potatoes evenly in the bottom of the prepared casserole dish.
    • Season the potato layer with a little salt and pepper.
    • Spread the mushroom and onion mixture evenly over the potatoes.
    • Add the remaining potato slices on top, seasoning again with salt and pepper.
    • Pour the creamy sauce evenly over the top, spreading it out with a spatula.
  5. Top with cheese and breadcrumbs (optional):

    • Sprinkle the remaining shredded cheddar cheese and Parmesan cheese over the top.
    • If using, mix the breadcrumbs or crushed crackers with melted butter and sprinkle this mixture over the cheese.
  6. Bake: Cover the casserole with foil and bake for 35-40 minutes. Then, remove the foil and bake for an additional 15-20 minutes, or until the potatoes are tender and the top is golden brown and bubbly.

  7. Serve: Let the casserole cool for a few minutes before serving.
