Ingredients You Will Need

For this easy tuna hotdish, you will need tuna, cream of mushroom soup, milk, mayonnaise, cheddar cheese, frozen peas, medium egg noodles, and crushed potato chips. These ingredients create a creamy, cheesy casserole with a golden, crunchy topping.

How to Make Tuna Hotdish

Start by boiling the egg noodles according to the package directions. Cook them until tender, then drain well. While the noodles are boiling, combine the tuna, cream of mushroom soup, frozen peas, milk, mayonnaise, and cheddar cheese in a large mixing bowl. Stir until the mixture is smooth and evenly combined, then set it aside.

When the noodles are finished cooking, drain them and transfer them to a 9×13 baking dish.

Add the creamy tuna and soup mixture to the noodles in the baking dish.

Stir well until all of the noodles are coated with the creamy mixture.

Place the baking dish in a preheated 350 degree oven and bake uncovered for about 30 to 40 minutes. The tuna hotdish is ready for the topping when it is hot and bubbling around the edges.

While the casserole is baking, place the potato chips in a zip-top bag.

Crush the potato chips into small pieces for the topping.

When the hotdish has finished its first bake, remove it from the oven and sprinkle the crushed potato chips evenly over the top. Return the dish to the oven for another 5 to 10 minutes, or until the chips are lightly golden brown.

If you are short on time, you can use the broiler to brown the chips more quickly. However, watch the dish very closely if you choose this method. Potato chips can burn fast under the broiler, so do not walk away from the oven.

Once the topping is golden and crisp, remove the tuna hotdish from the oven and let it sit briefly before serving. This creamy tuna noodle hotdish pairs well with a fresh salad, simple vegetables, or fresh fruit for an easy complete meal.
