How to Make Tuna Noodle Casserole
Step 1 – Prep the oven and dish
Preheat the oven to 350°F and spray a 9×13 casserole dish with non-stick cooking spray.
Step 2 – Mix the casserole filling
In a large bowl, combine cooked egg noodles, frozen peas, drained tuna, cream of mushroom soup, milk, 1¼ cups cheddar cheese, celery salt, pepper, and parsley.
Step 3 – Add to the baking dish
Spread the tuna mixture evenly into the prepared casserole dish.
Step 4 – Bake covered
Cover the casserole and bake for 20 minutes, until hot and bubbly.
Step 5 – Make the topping
While the casserole bakes, mix the bread crumbs with melted butter.
Step 6 – Add the topping
Remove the casserole from the oven and sprinkle the buttered breadcrumbs and remaining ¼ cup cheddar cheese over the top.
Step 7 – Finish baking
Return the casserole to the oven and bake uncovered for 5 to 10 minutes, until the breadcrumbs begin to brown and the cheese is melted.
Step 8 – Serve warm
Let it rest briefly, then serve warm with extra parsley if desired.
What to Serve Them With
Serve this casserole with a crisp green salad for a fresh contrast.
Pair it with roasted vegetables for a simple, balanced dinner.
Garlic bread or dinner rolls also work well for soaking up the creamy sauce.
Variations / Substitutions
Swap mild cheddar for sharp cheddar if you want a stronger cheese flavor.
Use crushed crackers instead of breadcrumbs for a more buttery topping.
Add sautéed mushrooms, diced onion, or celery for extra texture and flavor.
Use cream of celery soup instead of cream of mushroom soup for a slightly different taste.
Storage & Leftovers
Store leftovers in an airtight container in the refrigerator for up to 3 days.
Reheat individual portions in the microwave until warmed through.
For best texture, reheat larger portions in the oven so the topping can crisp again.
