What is a Casserole?

I get asked this a lot! I am always shocked but also so happy to always explain. It is a mom’s best friend and a simple way to make a delicious homemade dinner in one pan. A casserole is a baked dinner dish that is filled with all the ingredients you need in order to make a complete meal. Usually a casserole is baked in a deep pan that is filled with a mixture or layers of ingredients then baked all together. Hopefully this the first of many casseroles that you make!

Tuna Noodle Casserole Ingredients:

Don’t let this ingredient list scare you away! It is a lot and looks intimidating. It is a simple casserole dish that is quick and easy to prepare, mix and bake all together. Each ingredient makes this casserole a perfect combination all mixed together.

  • Noodles: Wide Egg noodles soak up more and hold a thickness after being
  • Olive Oil: Helps sauté the vegetables together as well as adds a little flavoring at the same time. 
  • Onion: small is best. Not everyone loves onions and I understand that. You are welcome to omit the onion.
  • Celery: Pre-dice the celery the best you can at the thickness you prefer.
  • Mushrooms: Sliced up is best and in thin slices.
  • Butter: This butter and flour mixture is going to create a thickener for the sauce when baking.
  • Flour: Thicken a roux to make a sauce within the casserole.
  • Chicken Broth: Adds flavor as well as a thickener.
  • Milk: Whole milk is best for the thick sauce over the noodles.
  • Salt and Pepper: Just a pinch of each for taste and flavoring.
  • Tuna Fish: Cans of white albacore is my preferred choice but any tuna is delicious.
  • Frozen Peas: Thaw the peas before adding them into the noodle mix. 
  • Cheddar Cheese: Shredded is best and easier to sprinkle.
  • Parmesan: Grated in a bottle works well for the topping.
  • Breadcrumbs: Italian adds flavoring and gives it a thin crust layer.
  • Butter: Melt the butter and drizzle over top creating a harder crust when baking.

How to Make Tuna Noodle:

  1. Boil Pasta: Preheat oven to 375 degrees.  In a large pot boil the pasta according to package directions and drain and rinse. 
  2. Sauté vegetables: In a medium skillet over medium high heat add the olive oil, onion, and celery.  Sauté for 2-3 minutes until almost tender.  Add in the mushrooms and continue to sauté until tender.  Add to a large bowl.
  3. Create a roux: Add the butter to the skillet and whisk the flour until golden.  Slowly whisk in the chicken broth and milk.  Let simmer until thickened.
  4. Add to casserole dish: In the large bowl add the pasta, tuna, peas, and cheese.  Mix together.  Spread evenly in a 9×13 inch casserole dish.  In a small bowl combine parmesan, breadcrumbs, and butter.  Sprinkle on top of casserole.
  5. Bake at 375 degrees: Bake for 25-30 minutes or until bubble and golden brown on top.

The Recipe Critic Pro Tip:

Undercook the pasta when making it. It will finish cooking in the casserole while being baked.

Variations for Homemade Tuna Casserole:

Tuna casserole can be made a few different ways. Making it your own and how your family prefers is the best way to enjoy this dinner.

Here are a few ideas of omitting or substituting ingredients:

  • Tuna Fish: If the tuna fish is not your favorite try shredded chicken in replace of it.
  • Noodles: Whole wheat, bowtie, macaroni or any other noodles that you prefer to cook.
  • Vegetables: Add in or omit any vegetable that you are not sure of. Just know that each ingredient really blends in this casserole.
  • Cheese: Try different cheeses to make a variety of casserole options. Jalapeño or cheddar jack are also fun ways to add a little heat.

Let’s Freeze it!

Yes, you can freeze this casserole. Fortunately, there are two ways to freeze it. Make ahead method or freeze the leftovers that you were not able to finish.

  • Make Ahead: It is best to prepare everything and follow the instructions on how to bake it. Once you get to baking, skip and place in a air tight container or wrap tight with foil or wrap. Then place in the freezer for 1 to 2 months. When ready to warm up, let thaw in the refrigerator overnight. Top with parmesan and Italian bread crumbs then bake at 375 degrees Fahrenheit for 30 minutes.
  • Freeze Left Overs: This is simple to do and a great practice for left overs. Place the left overs in an airtight container and lay flat in the freezer. Thaw over night in the refrigerator and reheat in the microwave or oven.

    The casserole tasted great and we really liked it. I’ll definitely make it again. The recipe didn’t tell you when to add the roux so I poured the roux on the top of everything after I put it in the casserole dish and before I added the topping.

  2. This is not everyone’s great aunts tuna casserole 😂. This is the best! So delish!!!!!! Great recipe… I love all of your recipes and have never been disappointed!!

      We drizzled the roux in over all the ingredients mixed together in our casserole dish and just let it percolate through with some gentle mixing. Then added the cracker mix on top before going into the oven. Worked fine.

  3. Can you tell me what the serving size is? Trying to see if it will fit into my daily Diabetic diet plan.


    1. The serving size is about 1 cup per serving per person. These are rough estimates and something to use however, is not 100% accurate.
