Easy Tuna Noodle Casserole Recipe

I love this easy tuna casserole recipe. It’s creamy, it’s cheesy, it’s packed with the best combination of flavors and textures, and it’s so simple to make right at home! 

To make this recipe, you just cook up some egg noodles, put together a simple cream sauce, layer it into a casserole dish with canned tuna, then top it off with crushed Ritz crackers and bake.

This recipe serves a ton, makes great leftovers, and is a family favorite! It’s big flavor with minimal effort.

How to Make Tuna Noodle Casserole from Scratch

You’ll find the exact measurements and full instructions in the recipe card near the bottom of the page.

Our delicious tuna noodle casserole is simple to prepare and bakes in about 30 minutes. It’s warm, cheesy, and has the best crunchy topping.

  1. Bring a large pot of salted water to a boil and cook the noodles of your choice until al dente. Drain and set aside. 
  2. Heat an oven-safe skillet over medium heat on the stove, then add in the mushrooms, butter, and seasonings. Cook until the mushrooms shrink and soften.
  3. Add in the cream soup and half-and-half. Mix until well-combined and stir in 1 cup of cheese.

  2. In a bowl, combine crushed crackers and melted butter. After 20 minutes, uncover the casserole, sprinkle the top with the cracker mixture, then bake uncovered until the crackers are golden brown.

Tips and Notes

  • Cook the noodles al dente. They will continue to cook slightly when the casserole bakes, so initially cooking them al dente helps prevent them from being too mushy. 
  • Bake covered first. For the first 20 minutes of baking time, I recommend covering the casserole with foil. This allows it to heat all the way through without burning on the top.
  • Let it rest before serving. I give the tuna casserole 5-10 minutes to rest before I serve it up. Just a few minutes gives it time to thicken up a bit.
  • If you don’t have a large oven-safe dish, use a 9×13-inch baking pan for the casserole and cook the filling in a separate skillet.

Storage

Leftover tuna casserole can be stored in an airtight container in the fridge for up to 5 days.

Can I Freeze Tuna Noodle Casserole?

Tuna casserole freezes well for about 2 months. Make sure to cool completely before placing the casserole in the freezer.

The cracker topping may not be as crispy after the casserole thaws and is reheated. Remove the crackers from the top of the casserole if desired.

When you’re ready to enjoy your casserole again, let it thaw overnight in the refrigerator if it’s frozen, set it out on the counter for 30 minutes, then reheat in the oven at 350ºF until heated through. 

You may need to cover the baking dish again to make sure the top doesn’t burn.

Can You Make Tuna Noodle Casserole Ahead of Time?

To assemble tuna casserole ahead of time, follow the instructions for cooking the filling and putting together the casserole, but leave off the cracker topping and don’t bake. 

Instead, let the casserole cool completely, then cover it and store it in the fridge for 1-2 days. Alternatively, wrap the casserole tightly in plastic wrap and foil and store it in the freezer for up to 2 months.

When you’re ready to bake, thaw the casserole overnight in the fridge, let it come to room temperature for 30 minutes, then add the topping and bake as directed!

What Kind of Tuna is Best for Tuna Casserole?

You can use whatever variety of canned tuna is your favorite. 

The one thing I do recommend using is flaky tuna packed in water to avoid any excessive oiliness in the casserole! Chunk light tuna in water is our pick.

Why is My Tuna Noodle Casserole Dry?

This casserole is far from dry. So, if yours ended up a little bit too dry, then it’s likely over-cooked. 

To prevent this from happening, make sure that you cover the baking dish with foil or a lid for the first 20 minutes of baking time. 

This traps the heat in and keeps the casserole nice and moist! You can also add an extra splash or two of half and half, milk, or chicken broth if the filling appears dry.

Should You Serve Casseroles Immediately?

You absolutely can, but you also don’t have to! The beauty of casseroles is that they are so easy to prepare ahead of time. 

You can bake and store your casserole as directed above under “storage” OR you can assemble the casserole in advance to bake later on.

    Delicious, I added a half cup Mayo, to add a little zing to the casserole. Will definitely make again.
