Ingredients for campbell's cream of mushroom soup tuna casserole
Six simple ingredients transform into nostalgic, cheesy, crispy perfection in one pan.
| Ingredient | Amount | Notes |
|---|---|---|
| Campbell's Cream of Mushroom Soup 🍲 | 2 cans | Condensed, not ready-to-serve |
| Canned Tuna in Water 🐟 | 2 cans | Drained, not oil-packed |
| Egg Noodles 🍝 | 2 cups | Uncooked, medium width |
| Sharp Cheddar Cheese 🧀 | 2 cups | Shredded, not pre-shredded |
| Milk 🥛 | ½ cup | Whole milk for creaminess |
| Butter 🧈 | ½ cup | Unsalted, melted |
| All-Purpose Flour 🌾 | ¼ cup | For cheesy topping |
| Garlic Powder 🧄 | 1 tsp | Freshly ground preferred |
| Onion Powder 🧅 | 1 tsp | For depth of flavor |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
| Panko Breadcrumbs 🍞 | ¼ cup | For extra crunch |
| Green Onions 🧅 | 2 whole | Chopped, for garnish |
The cheddar is non-negotiable here—Kraft 2-year aged or Cabot make all the difference. Pre-shredded cheese gets clumpy and lacks flavor, so grab a block and shred it yourself. The tuna? Wild-caught if you can find it, but regular works fine too. For the noodles, Barilla or De Cecco hold up best to baking. Campbell's soup is a pantry staple, but if you want to elevate it, add a pinch of Worcestershire sauce to the filling for extra depth. The butter matters too—Land O'Lakes or Plugrah melt beautifully for that rich topping.
No panko? Regular breadcrumbs toasted in a dry pan work in a pinch. Short on green onions? Fresh chives or dried parsley add color. The milk can be skim if you're watching calories, but whole milk makes the topping extra luscious. For a dairy-free version, swap the milk for unsweetened almond milk and use vegan cheddar. The garlic and onion powders are easy to find at Walmart or Target, but if you want to splurge, Penzeys has a great selection of high-quality blends. The key is balancing the flavors—don't skip the salt, even if the soup already has some.
This casserole reheats beautifully—just cover with foil and bake at 350°F for 15 minutes. It keeps for 4-5 days in the fridge, but honestly, it disappears faster than that. For meal prep, assemble it ahead and refrigerate overnight—the flavors meld even better. The topping gets crispier if you bake it a few minutes longer, so keep an eye on it. Leftovers freeze well for 3 months, but trust me, you won't have any. Double the recipe and freeze half—future you will thank present you.
Why You'll Love This Recipe
- No-Brain Mixing: I swear by this recipe because it’s the kind of dish where you literally just dump everything in one bowl. The soup, drained tuna, noodles, milk, and cheese all go in together—no measuring cups, no fancy techniques. Honestly, I’ve made it while scrolling through my phone, and it still comes out creamy and satisfying.
- Cheesy-Tuna Magic: That moment when the cheddar melts into the creamy mushroom soup? Chef’s kiss. The sharp chedddar cuts through the richness of the soup while the tuna adds a briny punch—it’s like a hug in a casserole. Plus, the egg noodles soak up all the flavor without getting mushy (if you cook them just right).
- Lunchbox Hero: Between us, this is my go-to for meal prep. I make a big batch on Sundays, portion it into containers, and boom—lunches for the week. It reheats like a dream (microwave or oven, no judgment) and even kids will eat it because it’s not "bland school lunch" territory.
- Budget Win: I’m not kidding when I say this feeds four for under $10. Canned tuna, a can of soup, a bag of noodles, and a block of cheese? That’s a stretch for any grocery budget. And leftovers? They taste just as good the second day—sometimes even better, because the flavors meld overnight.
Step-by-step instructions for campbell's cream of mushroom soup tuna casserole
Here's how to make this comforting casserole with a golden, crispy topping that's easy to achieve.
Cook the Egg Noodles Al Dente
Bring a large pot of water to a rolling boil and add 2 cups of egg noodles. Cook until they're just barely al dente—about 1 minute less than the package directions suggest. You want them to finish cooking in the oven, which helps them absorb all that creamy mushroom flavor. Drain the noodles and set them aside in a large bowl.
While the noodles cook, open both cans of Campbell's Cream of Mushroom Soup and pour them into the bowl with the drained noodles. Stir everything together until the noodles are fully coated in the creamy sauce. This step ensures every bite is packed with flavor, not just the top layer.
Add the Tuna and Seasonings
Drain the 2 cans of tuna in water thoroughly and add them to the noodle mixture. Break up any large chunks with a fork so they distribute evenly. Stir in the 0.5 cup of milk, 1 teaspoon of garlic powder, 1 teaspoon of onion powder, 0.5 teaspoon of salt, and 0.25 teaspoon of black pepper.
Mix everything together until the tuna is fully coated and the seasonings are evenly distributed. The milk adds creaminess without making the casserole too heavy. Taste the mixture now—you should be able to detect the savory mushroom flavor and the subtle garlic and onion notes. If it needs more seasoning, adjust with a pinch more salt or pepper.
Prepare the Cheesy Crispy Topping
In a medium bowl, melt the 0.5 cup of butter in the microwave for 30-45 seconds or until completely liquid. Stir in the 0.25 cup of all-purpose flour until you have a smooth paste. This mixture is the secret to that perfect crispy topping—it creates a golden, crunchy crust that contrasts beautifully with the creamy filling.
Add the 2 cups of shredded sharp cheddar cheese and mix until fully combined. The cheese should be evenly distributed in the buttery mixture. Sprinkle in the 0.25 cup of panko breadcrumbs and stir again. The panko adds texture and helps create that satisfying crunch when you cut into the casserole.
Assemble and Bake to Golden Perfection
Preheat your oven to 375°F. Transfer the noodle-tuna mixture to a greased 9x13-inch baking dish. Spread it out evenly so it's about ½-inch thick. This even distribution ensures the casserole cooks uniformly and the topping crisps properly.
Spoon the cheesy topping mixture evenly over the top of the casserole, using the back of a spoon to spread it into an even layer. Sprinkle the chopped 2 whole green onions over the top for a pop of color and freshness. Place the baking dish on a rimmed baking sheet to catch any potential spills.
Bake Until Bubbly and Golden
Bake the casserole for 25-30 minutes until the top is deep golden brown and the edges are bubbling. You'll know it's ready when the cheese topping looks crispy and the filling is heated through. The casserole should smell rich and savory—like a cozy hug in dish form.
Let it rest for 5-10 minutes before serving. This resting time allows the layers to set slightly, making it easier to cut and serve. The crispy topping will stay crunchy, while the creamy filling remains perfectly heated. Serve with a side of steamed green beans or a simple salad for a complete meal.
Pro Tips For Making Campbell'S Cream Of Mushroom Soup Tuna Casserole
- Drain and Pat the Tuna: That waterlogged tuna is the fastest way to turn your casserole into a sad, watery mess. Drain it well, then press it between paper towels to squeeze out every drop—this keeps the texture firm and the sauce from turning into soup. (Yes, even if you’re impatient like me.)
- Pre-Cook the Noodles Al Dente: Undercooked noodles turn mushy when they sit in the hot soup, while overcooked ones get gummy. Boil them just until they’re firm to the bite (about 1 minute less than package instructions), then drain and toss with a little oil so they don’t stick. Trust me, this makes all the difference when they absorb the sauce.
- Mix the Cheese Last: Stirring in the cheddar too early makes it clump like glue. Wait until the soup is just simmering, then sprinkle the cheese in small batches while stirring vigorously—this melts it smoothly instead of creating a grainy, lumpy disaster. (And skip the pre-shredded kind; it’s coated with anti-caking agents that turn rubbery.)
- Add a Splash of Milk: The soup can get thick and heavy if you skip this. After mixing in the tuna and noodles, stir in ¼ cup of milk to loosen the sauce and balance the richness. It also helps the cheese melt more evenly—no one wants a casserole that’s basically a cheese brick.
Flavor customization for these flavors
Spicy Kick
Add 1-2 teaspoons of hot sauce (like Crystal or Tabasco) or ½ teaspoon of cayenne pepper to the soup mixture for a subtle heat. For a smoky kick, stir in ½ teaspoon of smoked paprika with the garlic and onion powders.
I like Cholula for a tangy-spicy twist—just a splash adds depth without overpowering the creamy base. 🌶️
Herb Infusion
Brighten the dish with 1 tablespoon of fresh parsley or dill, finely chopped, mixed into the filling. For a Mediterranean twist, add ½ teaspoon of dried oregano or thyme alongside the garlic powder.
Fresh herbs like basil or chives in the topping add a vibrant contrast to the cheesy crust.
Vegetable Boost
Stir in 1 cup of frozen peas or corn (thawed) with the tuna for a pop of color and texture. For a heartier dish, add 1 cup of diced bell peppers or zucchini—they soften perfectly during baking.
I love roasted red peppers for a smoky, sweet note that pairs beautifully with the mushroom soup.
Cheese Variations
Swap the cheddar for Monterey Jack for a milder, creamier topping or Gruyère for a nutty, complex flavor. For a fun twist, mix in ½ cup of pepper jack with the cheddar—it adds a mild heat and vibrant color. A sprinkle of parmesan on top before baking gives extra crispiness.
Crunchy Toppings
Boost texture with ½ cup of crushed potato chips (like Ruffles) mixed into the topping for a salty crunch. Bacon bits or crumbled bacon add smokiness, while toasted nuts (like pecans or walnuts) bring a sweet contrast. For a gluten-free option, use crushed cornflakes instead of panko.
Tangy Twist
Stir 1 tablespoon of Dijon mustard into the soup mixture for a sharp, tangy depth. A splash of lemon juice (about 1 teaspoon) brightens the flavors, especially if you’re using wild-caught tuna. For a creamy tang, swap half the milk for sour cream in the topping mixture.

Frequently asked questions
Can I use oil-packed tuna instead of water-packed?
Yes, but drain the oil completely—it can make the casserole too greasy. For every can of oil-packed tuna, pat the drained fish with a paper towel to absorb excess moisture. The texture will be slightly richer, but the creamy soup base balances it perfectly.
How do I prevent a soggy topping?
Bake the casserole on the middle oven rack for even heat exposure. Spread the topping thinly and avoid overmixing the cheese-butter mixture. For extra insurance, broil for 1-2 minutes at the end (watch closely!) to melt the cheese without steaming. The panko should stay crispy, not mushy.
Can I make this ahead of time?
Assemble the dish up to 24 hours ahead and refrigerate uncovered. The flavors meld beautifully overnight. Bake straight from the fridge, adding 5-10 extra minutes at 375°F to compensate for the cold start. For make-ahead freezer meals, assemble and freeze unbaked (cover tightly with foil). Bake from frozen, adding 10-15 extra minutes.
What’s the best way to reheat leftovers?
Cover loosely with foil and reheat at 350°F for 15-20 minutes until bubbly. For microwave reheating, sprinkle 1 tablespoon of water over the top and cover for 1-2 minutes on medium power. The topping may soften slightly—broil for 30 seconds afterward to restore crispiness.
Can I substitute another type of pasta?
Stick to small, sturdy shapes like macaroni, cavatappi, or shell pasta—they hold up best to baking. Avoid delicate noodles like angel hair, which can turn mushy. For extra flavor, try whole wheat or tricolor rotini, but reduce baking time by 2-3 minutes to prevent overcooking.
