Tuna noodle casserole is the dish I turn to when I want pure nostalgia in a baking dish. It brings together tender noodles, a rich creamy sauce, flaky tuna, and sweet peas all sealed under a golden, crunchy topping. Whether you are feeding a crowd or seeking comfort after a long day, this recipe delivers an easy one-dish wonder that is big on coziness and flavor.

Anytime I need to bring a warm hug to the table, I make this casserole for my family. The first time I tried it, my dad said it tasted just like his mother’s. Now my kids ask for it when the weather turns chilly or whenever they need a little extra comfort.

Ingredients

  • Egg noodles: Wide noodles are key for soaking up sauce and providing a toothsome bite Choose ones that hold up well after baking
  • Tuna: Go for solid white albacore packed in water for the cleanest taste and largest flakes Drain it well for best texture
  • Frozen peas: These guarantee pops of sweetness and color with no prep needed Pick a bag with bright green color and no clumping
  • Sliced mushrooms: A can is classic and easy but firm fresh mushrooms work just as well if you have them
  • Salt: A good pinch in the pasta water enhances every layer
  • Unsalted butter: Forms the base of your roux for a creamy sauce Choose fresh butter for better flavor
  • All-purpose flour: Thickens your sauce quickly and smoothly Sift it first if it is lumpy
  • Whole milk: The key to luxurious creaminess Use milk with some fat for the richest texture
  • Cream of mushroom soup: The shortcut for the deep savory undertone Go for good-quality brands with visible mushroom pieces
  • Sharp cheddar cheese: Provides tang and pulls the whole dish together Freshly shredded melts smoother
  • Garlic powder and onion powder: Help savoriness bloom without chopping or peeling
  • Salt and black pepper: To season your sauce precisely Taste as you go
  • Panko breadcrumbs: Deliver the golden crunch on top Look for unseasoned for full control
  • Melted butter: Ensures the topping bakes up crisp instead of dry
  • Parmesan cheese: Adds nutty depth and browns beautifully Use real Parmigiano if you can
  • Fresh parsley: Brings fresh flavor and a pretty green finish Use the brightest leaves available

Instructions

Cook the noodles:
Boil wide egg noodles in generously salted water until just al dente The noodles will finish cooking in the oven so check them two minutes before the package says they are done Drain well and set aside

In a large saucepan melt butter over medium heat Let it foam and subside before whisking in the flour Cook for one to two minutes whisking constantly until the raw flour smell fades and the mixture turns pale and smells nutty Slowly pour in whole milk while constantly whisking to prevent lumps Once smooth add the cream of mushroom soup Stir well Bring to a low simmer and cook until slightly thickened about three to four minutes
Add cheese and seasonings:
Take the saucepan off the heat and sprinkle in freshly shredded cheddar cheese garlic powder onion powder salt and black pepper Stir until cheese is completely melted and everything is evenly combined Taste and adjust seasoning as needed
Combine ingredients:
Dump drained noodles tuna peas and mushrooms into the prepared baking dish Pour all of the creamy cheese sauce over top Use a large spoon to gently fold everything together making sure the sauce coats the noodles evenly and the tuna stays chunky
Prepare topping:
In a small bowl stir together panko breadcrumbs melted butter grated Parmesan and chopped parsley until all the crumbs are moist Sprinkle evenly over the casserole making sure to reach all corners
Bake:
Cover the casserole tightly with foil and place in a preheated 350 degree oven Bake for twenty minutes then remove the foil and continue baking for ten minutes or until the top is golden brown and the sauce is bubbling at the edges Set aside to rest for five minutes before serving this allows the sauce to set and makes it easier to slice

My favorite part is always the cheesy golden crust I often catch my family fighting good-naturedly for the crunchy corners It reminds me of when my grandmother used to sneak slivers of the topping before anyone else could get to it She always claimed she was just making sure it was crispy enough

Leftovers keep well in the fridge for up to four days Store them tightly covered to lock in moisture To reheat cover loosely with foil and warm at 325 degrees until heated through A quick blast under the broiler will re-crisp the topping

Ingredient Substitutions
