Why this tuna casserole is so easy

This tuna casserole made with chow mein noodles and cream of mushroom soup is an old family recipe from the 60’s that is super easy to make.

And here’s all the reasons it’s one of my all-time favorites:

  • It’s ready in less than an hour.
  • It’s made in the same oven proof dish that it’s baked in. Which means no extra mess to clean up.
  • It also uses chow mein noodles instead of pasta so there’s one less prep step. The noodles are added right out of the package, so you don’t have to cook them first. (And they add the perfect crunch to the topping!)
  • Finally, it’s really easy to make ahead of time so it’s great to take to a potluck. Or if you’re doing meal prep in advance.


tuna casserole ingredients - chow mein noodles, canned tuna, cream of mushroom soup, onion, celery, salt and pepper

This recipe will make 4 to 6 dinner-sized servings.

Here is your shopping list:

  • Fresh vegetables – 2 to 3 stalks celery, 1 yellow onion
  • Canned goods – 1 10.5-ounce can condensed cream of mushroom soup, 1 5- to 6-ounce can tuna. I prefer white tuna but any variety of canned tuna will work.
  • International food – 1 12-ounce package or can chow mein noodles
  • Seasoning – Pepper to taste


  • Instead of onion: Substitute 1 cup shallots, finely chopped, for a milder flavor.
  • To add more flavor: Use ½ cup chicken broth or vegetable broth instead of water.
  • To replace the chow mein noodles: Use 1 package of crushed plain potato chips or fried onions for the crunchy topping, and substitute 1 cup cooked rice or 6 ounces pasta (already boiled) mixed into the casserole.


  • You’ll need a 1.5- to 2-quart square or round baking dish. I like to use my old glass Corning Ware bakeware for this.

How to make chow mein tuna casserole

1 | Prep Work

Pre-heat your oven to 375°F.

Start by dicing the onion. You’ll need enough for 1 cup.

Aim for uniform pieces to ensure they cook evenly. I like to use a mini food processor for this, but you can chop them by hand if you don’t have one.

Chop enough celery into thin slices to fill 1 cup.

Drain the liquid from the can of tuna.

2 | Cook the celery and onions

Combine 1 cup diced onions and sliced celery with ½ cup of water in a casserole dish.

Cover the dish and heat it on the stove top over medium heat.

Simmer for 5 minutes. The onions should be translucent and the celery soft.

Remove from the heat.

3 | Make the casserole

Add the can of soup (without adding any water), drained tuna, and a dash of pepper to the casserole dish with the celery and onions.

The soup will act as a creamy binder that holds all the ingredients together so you don’t want to thin it out too much by adding water.

Stir these ingredients until they are well combined.

Add in half of the chow mein noodles. These will soak up some of the liquid and flavor from the mixture and get soft while they are baking.

Top the mixture with the remaining chow mein noodles. Spread them evenly over the top. This layer will crisp up beautifully in the oven, providing a contrast to the creamy mixture below.

4 | Bake

Place the casserole in the pre-heated 375°F oven and bake for 30 minutes until bubbling and the top is crispy brown

Keep an eye on it as it cooks, especially towards the end of the time. If the top is browning too quickly, you can loosely cover it with aluminum foil to prevent burning.

Serving suggestions

Garnish the tuna casserole with freshly chopped parsley or green onions for a pop of color and freshness.

For added flavor, sprinkle grated Parmesan cheese over the top just before serving.

Serve alongside a crisp green salad dressed with a light vinaigrette, grilled asparagus or herbed broccoli.

And a side of crusty garlic bread to complement the creamy texture of the casserole.


Allow the tuna casserole to cool to room temperature, then cover it tightly with a lid, plastic wrap or aluminum foil.

Or transfer it to an airtight container, and refrigerate for up to 5 days.

Make sure it cools down to room temperature before storing to avoid condensation that can make the topping soggy.

For longer storage, freeze it in a freezer-safe container for up to 2 months, thawing overnight in the refrigerator before reheating in the microwave.

The chow mein noodles on top will not be as crispy after they have been reheated. But the dish still tastes great.

How to make ahead of time

To make tuna casserole ahead of time, prepare the recipe up to the point of putting on the chow mein noodle topping (before baking).

The noodles on top will get soggy if you put them on too early, so hold off on adding them until you are ready to cook it.

Cover the casserole dish with a lid or tightly wrap it with plastic wrap or aluminum foil, and refrigerate for up to 24 hours.

When ready to serve, remove the cover, sprinkle on the chow mein noodles and bake as directed. You may need to add an extra 5 to 10 minutes cooking time if the casserole is cold from the refrigerator.
