With just a handful of simple ingredients and hardly any prep it is a classic I keep in my weeknight rotation. Tender noodles tossed with creamy mushroom sauce and hearty tuna then baked till bubbling this dish brings back the nostalgic flavors I grew up with and now pass along for my own crew.
This was actually the very first dinner I learned to make on my own. It has bailed me out of countless last minute situations and always gets those smiles around the table.
Ingredients
- Egg noodles: these soak up the sauce and stay tender look for ones that hold their shape when cooked
- Tuna in water: brings protein and a satisfying bite try to choose wild caught for fresher flavor
- Cream of mushroom soup: creates a thick savory base go for a brand you trust for better taste and fewer additives
- Milk: adds creaminess and helps everything blend together whole milk is extra rich but any type will work
- Frozen peas: provide pops of color and a touch of sweetness use bright green peas that are not freezer burned
- Breadcrumbs (optional): these add crispy topping use panko for a crunchier finish
- Shredded cheddar cheese (optional): gives a gooey golden layer use sharp cheddar and grate it fresh if possible
Instructions
- Prepare the Oven:
- Preheat your oven to three hundred fifty degrees Fahrenheit set a rack in the center position so the casserole heats evenly
- Boil and Drain Noodles:
- Fill a large pot with salted water bring it to a boil then cook the egg noodles just until tender about six or seven minutes drain the noodles and return them to the pot so they do not overcook
- Mix Sauce:
- In a mixing bowl use a whisk to thoroughly combine cream of mushroom soup with milk stir until the mixture is perfectly smooth with no lumps
- Combine Everything:
- Add drained tuna make sure to break it up gently with a spoon and frozen peas straight from the bag into the noodles pour in the soup mixture and fold gently until all noodles are coated and the ingredients are well distributed
- Assemble in Dish:
- Lightly grease a two quart casserole dish with a bit of oil or nonstick spray transfer the noodle mixture into the dish and smooth the top with a spatula for an even layer
- Add Toppings:
- If desired sprinkle breadcrumbs evenly over the top for crunch and scatter shredded cheddar cheese for a melty finish press lightly so the toppings stick
- Bake Until Bubbling:
- Place the casserole uncovered in the oven bake for about twenty minutes or until it is hot bubbly and the toppings are just golden watch the last few minutes so it does not overbrown
- Rest and Serve:
- Let the casserole sit for five minutes before serving this helps the sauce thicken so every scoop holds together perfectly

I absolutely love using sharp cheddar cheese as my topping because it gets that irresistible crispy edge in the oven. Every time I pull this casserole out I remember my grandma letting me take the first cheesy corner piece as a kid.
Storage Tips
This casserole holds up great for leftovers just cover and store in the fridge for up to three days. Reheat individual portions in the microwave or warm the whole dish in a low oven covered with foil to prevent drying. For best results do not freeze with the breadcrumb topping add it fresh when reheating after thawing.
Ingredient Substitutions
Swap the egg noodles for rotini or even penne if needed. Use canned salmon instead of tuna for a twist. Cream of celery or chicken soup can slide right in if you are not a mushroom fan.
Serving Suggestions
A crisp green salad with tangy vinaigrette makes a fantastic side. Steamed broccoli or green beans add crunch and color. I love serving this casserole with dill pickles or a squeeze of lemon for bright contrast.
Cultural and Historical Context
This classic dish became popular mid twentieth century when canned goods and convenience cooking boomed in American kitchens. It is a shining example of resourcefulness making protein stretch to feed a family satisfying both nostalgia and practicality. The tradition continues because it is tasty filling and so easy to make.
Seasonal Adaptations
Use fresh peas or chopped asparagus in spring for a lighter feel. Stir in sautéed mushrooms or caramelized onions for fall depth. Try roasted red peppers or corn in summer when available. Cook noodles just until barely tender before baking for the best texture. Generously grease your casserole to avoid sticking. Sharp cheese gives the richest flavor as a topping.
Success Stories
I shared this recipe with my college roommate who has since made it her signature potluck dish for every gathering. One busy holiday season I prepped two casseroles in advance and the comfort of that first bite together made the chaos fade away. My nephew who swore he did not like tuna now requests this every time he visits.
Freezer Meal Conversion
Assemble the entire casserole in a freezer safe dish but skip the crispy topping until you are ready to bake. Label and freeze for up to two months then thaw overnight in the fridge and bake as directed adding toppings at the end. Perfect for busy weeks or thoughtful home cooked gifts.
