This classic tuna casserole is a classic mixture of tuna, noodles, and a flavorful homemade sauce (no soup!). I used frozen thawed peas in this dish, but feel free to use lightly cooked frozen mixed vegetables or a peas and carrots blend.

Serve this inviting tuna noodle casserole with a tossed salad or fresh sliced tomatoes and cucumbers.

If you aren't a fan of mushrooms, leave them out, or saute some onions or celery to replace them.

*Expert Tips

As loaf bread becomes a bit stale, tear it into pieces and process in a food processor until finely ground. Freeze the crumbs in a food storage bag and use as needed for casseroles or other dishes calling for bread crumbs.

For toasted bread crumbs, spread the crumbs out on a rimmed baking sheet and bake in a preheated 325 F (165 C/Gas 3) oven for about 12 to 14 minutes, until browned and crunchy.  See How to Make Easy Toasted Bread Crumbs for flavor ideas.


  • Substitute French fried onion rings or potato chips for the buttered bread crumb topping.
  • Instead of mushrooms, saute  1/2 cup of thinly sliced celery or a combination of the celery with 1/4 cup of chopped onion.
  • Add 1 cup of shredded cheese to the thickened sauce before you add the mayonnaise.
