Quick & Easy Tuna Casserole topped with a Cheese Blend or Crumb topping and baked in a casserole dish or single-serve Au Gratin Dish. This is a very old Recipe.

A simple but very comforting dish you can whip up in no time. I remember the first time I had it. It looked like an ordinary casserole and thought nothing of it. I took my first bite and was surprised. This tasted so good, I wanted seconds. Ever since, this has been a regular in our Family.

What Pasta is used for Tuna Casserole

Any Short Pasta will do, typically Macaroni. About 3 Cups of uncooked Pasta in total.

The Pasta is Boiled until just done. Strained and placed back into the pot with cold water to stop the cooking process. Once the Pasta has cooled down. Strain again and add back into the pot in preparation for all the other ingredients to go in.


Use canned Tuna to make this Pasta Bake. Strain well, squeezing all the juice out from 2 cans of Tuna in Water. Add it into the pot with the Pasta.

Tuna Casserole Sauce

The Sauce is made up of 1 can each, Cream of Mushroom & Cream of Celery Soup. This can be exchanged with other creams of soup that you prefer. A small amount of milk or cream is added. For creamier, add more Milk/Cream or a bit of Sour Cream.


Add in Green Peas and/or cooked Broccoli, shredded Carrots, Onions, Peppers, Celery, Leeks, Green Onions, Mixed Frozen Vegetables.

If using Onions, Celery, Peppers, or Leeks, sauté in butter before adding it to the rest of the ingredients to soften the vegetables up.

Tuna Casserole

Place all the mixed ingredients into a casserole dish (9×13 or smaller) and top. This gives you a thin, layered casserole with cheese. For me, this is preferable because it’s that cheese that really makes the whole thing come together. So a thin casserole with the cheese on top is perfect.

Place it into a smaller casserole dish if you want a thicker one.

Au Gratin

Place all the ingredients into a single-serve Au Gratin dish. The great thing about this method is that different people can have different toppings depending on what they are in the mood for. One person wants just the Mozza & Cheddar Cheese, another wants the 3 cheese, and yet another wants the Panko Crumb top. It can all be done with the Au Gratin dishes.

Just fill the Au Gratin dishes and place them on a baking sheet, and into the oven it goes.

Tuna Casserole Topping

There are two main toppings that can go on top, Cheese Topped or Crumb Topping.

Cheese Topping

You typically top with Marble Cheese. Although, shredded Mozza & Provolone Cheese at a ratio of 3:1 adds so much more to the dish. It makes a big difference. Add Cheddar Cheese for some sharpness. You can also use a Three Cheese Blend of Mozzarella, Monterey Jack, and Cheddar, Tex Mex, or Velveeta Cheese slices.

Add an Extra touch by drizzling melted butter over top of the cheese. Garnish it with Aleppo Chili Flakes & Parsley.

  • 1/4 tsp Onion, Garlic Powder
