Ingredients for tuna casserole recipe egg noodles cream of mushroom soup
Six cozy ingredients that melt into the ultimate comforting casserole—creamy, cheesy, and full of flaky tuna goodness.
| Ingredient | Amount | Notes |
|---|---|---|
| Egg Noodles 🍝 | 2 cups | Uncooked, medium width |
| Canned Tuna 🐟 | 2 cans | Flaked, in water or oil |
| Cream of Mushroom Soup 🍄 | 2 cans | Condensed, 10.5 oz each |
| Milk 🥛 | ½ cup | Whole for creaminess |
| Shredded Cheddar Cheese 🧀 | 1 ½ cups | Medium or sharp |
| Green Onions 🧅 | ¼ cup | Sliced, for freshness |
| Butter 🧈 | ½ cup | Unsalted, melted |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening sauce |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Garlic Powder 🧄 | 1 tsp | For savory depth |
| Dried Parsley 🌿 | 1 tbsp | For garnish |
| Breadcrumbs 🍞 | ¼ cup | Panko for extra crunch |
The tuna is the star here, so grab the highest quality canned tuna you can find—look for brands like Wild Planet or Starkist in water for flakiness. Egg noodles? Barilla or De Cecco are my go-tos—they hold up perfectly without getting mushy. Cream of mushroom soup is non-negotiable for that classic flavor, but if you're feeling fancy, you can make your own by blending sautéed mushrooms, cream, and a splash of chicken broth. The cheddar cheese should be shredded fresh (pre-shredded gets clumpy and doesn't melt as nicely). For the green onions, grab a bunch and slice them thin—you'll use the whites and greens for maximum flavor.
No cream of mushroom soup? Make your own with mushroom duxelles and cream—it's easier than you think. Running low on milk? Half-and-half or heavy cream will give you that ultra-creamy texture. Skip the breadcrumbs? A sprinkle of crushed potato chips or crushed Ritz crackers adds crunch without the extra effort. The garlic powder can be swapped for fresh minced garlic if you've got it—just use half the amount. And if you're watching calories, reduce the cheese to 1 cup and add a splash of milk to keep it creamy. The butter is key for that rich, velvety sauce, so don't skip it—trust me on the full-fat version!
This casserole reheats beautifully—honestly tastes even better the next day once everything melds together. Store leftovers in an airtight container in the fridge for up to 4 days. For meal prep, portion it into individual containers so you can grab and bake straight from the fridge. Freezes for 3 months if you want to make a big batch for the week. Just thaw overnight in the fridge before reheating. The breadcrumb topping gets extra crispy when reheated, so if you're serving it straight from the fridge, pop it under the broiler for 2-3 minutes to revive that golden crunch.
Why You'll Love This Recipe
- No-Sweat Assembly: I swear by this recipe because it’s the kind of meal where you just dump ingredients and walk away. Five minutes of stirring egg noodles into soup, tossing in drained tuna, and sprinkling cheese—no chopping, no sautéing, no stress. Honestly, the only harder part is deciding whether to eat it immediately or wait for the cheese to get extra gooey.
- Cheesy Mushroom Magic: That creamy mushroom soup base is where the flavor happens—rich, umami-packed, and somehow even better when mixed with milk and melted cheddar. The tuna soaks up all the goodness, and the egg noodles turn tender without turning mushy. (Yes, even on a Tuesday night.)
- Leftovers That Don’t Suck: This casserole actually tastes better the next day—crispier on top, flavors melded together. I make a double batch on Sundays, portion it out, and reheat slices straight from the fridge. No sad, dry leftovers here; just warm, comforting bites that disappear fast.
- Budget Meal for Busy Nights: Five dollars, three pantry staples, and you’ve got a filling dinner that feeds four. The canned tuna and boxed soup keep costs low, while the cheese stretches into maximum satisfaction. Between us? It’s my secret weapon for nights when takeout feels too expensive and cooking feels impossible.
Step-by-step instructions for tuna casserole with egg noodles
Here's how to make this creamy, comforting classic in one pan—no fancy skills required!
🍳 Step 1: Cook the Egg Noodles Al Dente
Bring a large pot of salted water to a rolling boil. Add the 2 cups egg noodles and cook for 8-9 minutes until they're al dente—still with a slight bite in the center. Drain immediately and set aside. Overcooking will make them mushy in the casserole.
While the noodles cook, melt the 0.5 cup butter in a large oven-safe skillet over medium heat. This butter will form the rich, creamy base of your casserole. Let it melt completely but don't let it brown—just until it's fully liquid and smells nutty.
👨🍳 Step 2: Build the Creamy Sauce Base
Reduce heat to medium-low and sprinkle the 2 tbsp all-purpose flour over the melted butter. Stir constantly for 1-2 minutes until the mixture turns a light golden color and smells toasty. This creates a roux that will thicken your sauce beautifully.
Slowly pour in the 0.5 cup milk while whisking continuously. Add one can of cream of mushroom soup and stir until smooth. Let the mixture simmer gently for 3-4 minutes until it thickens slightly. Here's the thing—this step prevents a watery casserole later.
🥘 Step 3: Combine All Ingredients
Add the drained egg noodles to the skillet and stir to coat them evenly in the creamy sauce. Gently fold in the 2 cans flaked tuna (drained if in oil), 1.5 cups shredded cheddar cheese, 1 tsp salt, 0.5 tsp black pepper, 1 tsp garlic powder, and 0.25 cup sliced green onions. Mix until everything is well combined and the cheese starts to melt.
Here's where the magic happens: sprinkle the 0.25 cup breadcrumbs evenly over the top. The breadcrumbs will create a crispy, golden crust while the casserole bakes. Don't skip this—it's what makes this dish irresistible!
🔥 Step 4: Bake to Golden Perfection
Transfer the skillet to a preheated 375°F oven and bake for 20-25 minutes until the top is deep golden brown and bubbly. The cheese should be fully melted with a few crispy spots on top. If it's browning too quickly, tent with foil to prevent burning.
For that restaurant-quality finish, broil for 1-2 minutes at the very end. Watch it closely—you want the breadcrumbs to turn golden brown, not black. Remove from the oven and let it rest for 5 minutes before serving. This resting time lets the cheese set slightly for easier slicing.
🍽️ Step 5: Garnish and Serve Warm
Sprinkle the 1 tbsp dried parsley over the top just before serving. The parsley adds freshness that cuts through the richness of the cheese and tuna. Serve immediately with a side of steamed green beans or a simple salad.
Each bite should deliver warm, creamy noodles with flaky tuna, melted cheddar, and that perfect crispy breadcrumb topping. The flavors meld beautifully when served fresh from the oven—this isn't a dish that waits!
Pro Tips For Making Tuna Casserole Recipe Egg Noodles Cream Of Mushroom Soup
- Cook Noodles Al Dente: Boil egg noodles one minute less than the package says—you’ll finish them in the casserole. I learned this the hard way after serving mushy noodles that turned to paste under the cheese. They’ll absorb liquid better when slightly firm.
- Drain Tuna Well: Open that can of tuna and press it dry with a paper towel—every bit of brine makes the casserole soggy. I used to skip this, and the texture suffered. Takes 30 seconds but saves the dish.
- Mix Cold Milk: Stir the cold milk into the soup last, right before adding it to the noodles. Hot soup curdles cold milk like a science experiment gone wrong. Let it warm slightly first if you’re impatient, but don’t overheat it.
- Layer Cheese Strategically: Sprinkle half the cheese on top, then add a final layer of cheese after baking—this guarantees a crispy, melty crust without burning the rest. Your future self will thank you when you cut into a perfect golden top.
Troubleshooting great tuna casserole recipe egg noodles cream of mushroom soup
Mushy Noodles Fix
If your egg noodles turn out mushy, it’s usually from overcooking or too much liquid in the casserole. First, cook the noodles al dente—just 8-9 minutes in boiling water, not until fully soft. Drain them completely and pat dry with a paper towel to remove excess moisture.
For extra insurance, I like to undercook the noodles by 1 minute and finish them in the oven with the casserole. This ensures they absorb the creamy sauce without falling apart. 🍝
Watery Sauce Solution
A watery casserole usually means the sauce wasn’t thickened enough. Start by making a roux—melt 0.5 cup butter, whisk in 2 tbsp flour, and cook for 1-2 minutes until golden. Then, simmer the sauce for 3-4 minutes before adding noodles and tuna.
If it’s still too thin after baking, sprinkle a mix of 1 tbsp flour and 1 tbsp cold water over the top and broil for 1-2 minutes to thicken it up. Trust me, this trick works every time!
Cheese Not Melting?
Shredded cheese clumping or not melting? It’s usually because of pre-shredded cheese (which contains anti-caking agents) or not enough moisture. Use freshly shredded cheddar—it melts like a dream. If the cheese still resists, add 2 tbsp milk or cream to the sauce before baking.
For extra insurance, cover the casserole loosely with foil during the first 15 minutes of baking to trap steam and help the cheese melt evenly. ✨
Breadcrumbs Staying Soft
If your breadcrumb topping isn’t crispy, it’s likely because it didn’t bake long enough or the oven wasn’t hot enough. Panko breadcrumbs work best—they’re lighter and crisp up faster. Spread them evenly over the top right before baking (not too early, or they’ll get soggy).
For extra crunch, broil for 1-2 minutes at the very end, watching closely to avoid burning. A hot oven (375°F) is key—don’t skip preheating!
Tuna Too Dry or Rubbery
Flaky tuna can turn rubbery if overcooked or if the casserole sits too long before baking. Drain the tuna well (especially if in oil) and fold it into the casserole just before baking. For extra moisture, add 1-2 tbsp milk or cream to the sauce.
If the tuna still seems dry, bake at a slightly lower temperature (350°F) for 5-10 minutes longer to let the cheese melt without overcooking the tuna. The goal is creamy, tender tuna, not tough! 🐟
Uneven Baking
If the edges brown too fast while the center stays undercooked, switch to an oven-safe skillet (like cast iron) instead of a baking dish. Skillets distribute heat more evenly.
For extra insurance, cover the casserole loosely with foil for the first 20 minutes, then uncover to let the top brown. If using a baking dish, rotate the pan halfway through baking to ensure even cooking.
A meat thermometer can help—aim for an internal temp of 165°F in the center. 🔥

Frequently asked questions
Can I use frozen egg noodles instead of fresh?
Frozen egg noodles work perfectly—just thaw them first by soaking in warm water for 5 minutes or pat them dry. They’ll hold up just as well as fresh noodles in the casserole. The key is to undercook them by 1 minute when boiling to prevent mushiness.
How do I make this dish vegetarian?
Swap the tuna for 1.5 cups of chickpeas or white beans (drained and rinsed) and add 1 tbsp soy sauce or Worcestershire sauce for umami depth. For extra protein, stir in 1 cup of crumbled tofu or 1 cup of diced potatoes (pre-cooked). The cream of mushroom soup will still provide that rich, savory base.
Can I make this ahead of time?
Yes! Assemble the casserole in an oven-safe dish, cover tightly with foil, and refrigerate for up to 24 hours before baking. For best results, bake it straight from the fridge—just add 5-10 extra minutes to the baking time. Leftovers reheat beautifully in the microwave for 1-2 minutes or in the oven at 350°F for 15 minutes.
What if I don't have cream of mushroom soup?
No problem! Make your own by blending 1 cup sautéed mushrooms with 1 cup heavy cream or milk and 1 tbsp flour until smooth. For a quicker fix, mix 1 cup sour cream with 1 tbsp Dijon mustard and 1 tsp mushroom powder (if available). The texture will be slightly different but still delicious.
Why does my casserole get watery?
Watery casseroles usually happen when the sauce isn’t thickened enough. Always make a roux (butter + flour) first to create a creamy base. If it’s still too thin after baking, sprinkle a mix of 1 tbsp flour and 1 tbsp cold water over the top and broil for 1-2 minutes to thicken it. The key is patience—simmer the sauce for 3-4 minutes before adding noodles.
