A delightful twist on the classic tuna casserole, this recipe combines creamy textures with a crispy topping for a comforting meal.
Preheat your oven to 350°F (175°C).
Ensure the oven is fully preheated before baking for even cooking.
Cook the pasta according to the package instructions until al dente. Drain and set aside.
Avoid overcooking the pasta as it will continue to cook in the oven.
In a mixing bowl, combine the onion, mushrooms, and tuna. Mix well.
Chop the onion finely for a more even distribution of flavor.
In another bowl, whisk together the condensed soup, milk, mayonnaise, pepper, salt, and garlic powder until smooth.
Use a whisk to ensure the sauce is lump-free.
Combine the pasta, tuna mixture, and sauce in a large bowl. Mix until everything is evenly coated.
Mix gently to avoid breaking the pasta.
Transfer the mixture to a buttered baking dish. Top with breadcrumbs mixed with melted butter.
Spread the topping evenly for a consistent crust.
Bake in the preheated oven for 30 minutes or until the top is golden brown and the casserole is bubbling.
Place the dish on a baking sheet to catch any drips.
Let the casserole cool for a few minutes before serving. Enjoy your meal!
Allowing the casserole to rest helps it set and makes serving easier.
