This classic tuna casserole is a classic mixture of tuna, noodles, and a flavorful homemade sauce–no soup! We used frozen thawed peas in this dish, but feel free to use lightly cooked frozen mixed vegetables or a blend of peas and carrots. If you aren't a fan of mushrooms, leave them out, or sauté some onions or celery to replace them.

To serve, complement this creamy casserole with a tossed salad or fresh sliced tomatoes and cucumbers.

  • As loaf bread becomes 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, like meatloaf.
  • For toasted breadcrumbs, 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.
  • Season the casserole to your liking. Salt and pepper can add additional flavor to this dish. If you use canned breadcrumbs or substitute with potato chips, go lighter on the salt, as these ingredients will already include salt. For a spicier take, add a pinch of red pepper flakes to the breadcrumb mixture.

Recipe Variations

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