How to make a tuna casserole recipe?

First, begin by preheating your oven to 425° F., greasing a two and a half (2.5) quart casserole dish, and mixing the breadcrumb ingredients.

The breadcrumbs and seasonings mixed in a small glass ramekin.

Also, it’s probably a good idea to dice the celery and onion; as well as, shred the cheese and open the cans of tuna.

Next, cook the egg noodles until they’re almost done or al dente as it’s called in the culinary industry.

After that, grab a skillet and place it over low-medium heat. Melt the butter and cook the celery and onions until they’re soft. It should take about five (5) minutes.

Now, combine the celery, milk, mushroom soup, noodles, onions, peas, shredded cheese, and tuna in a large mixing bowl.

The casserole ingredients have been transferred to a baking dish.

Use a wooden spoon to mix everything together. At this point, you can transfer the mixture to the casserole dish.

Then, top the tuna casserole with the breadcrumb mixture you prepared earlier.

Place the dish into the oven to bake for about sixteen (16) minutes or until it’s bubbling. Last, remove it from the oven and serve while warm.

That’s it, your easy tuna casserole recipe is done! Kim and I hope you enjoy the meal and wish you all the best 🙂

Can you freeze tuna casserole?

Absolutely, you can either do it before or after you bake the dish. Personally, I would freeze it beforehand, then pop it into the oven to bake once we’re ready to eat it.

How long is tuna casserole good for?

Once baked, the tuna pasta will hold in your fridge for up to three (3) days in a sealed container. In other words, it’s okay to eat for another three (3) days as long as it’s stored in the fridge.
