Ingredients for campbell's cream of mushroom soup tuna casserole

Pantry staples meet cheesy crunch perfection in this one-pan wonder.

The Campbell's cream of mushroom soup is the secret weapon here—unsalted version if you can find it, but regular works too. Grab the 10.5 oz cans from any grocery store; they're always in stock. For the tuna, water-packed is lighter, but oil-packed adds richness. The elbow macaroni? Medium or small shapes hold up best to the baking—no mushy pasta here. I always check the expiration date on the soup cans; older cans can make the dish taste flat. Pro tip: open the soup cans and give them a quick stir before using—settled ingredients taste better mixed in.

No panko? Regular breadcrumbs plus a pinch of salt work in a pinch, but panko gives that perfect crunch. Short on cheddar? Mozzarella or Monterey Jack blends beautifully—just add a splash of milk to help it melt smoothly. The butter and milk combo creates the creamiest sauce, but half-and-half works too if you're in a hurry. Flour is key for thickening—whole wheat works but can make the sauce gummy. Want more flavor? Add a dash of Worcestershire sauce with the soup. The garlic and onion powders are optional but take this from good to next-level—trust me, they make a difference.

This casserole tastes even better the next day—make extra and freeze portions for lazy weeknights. Store leftovers in the fridge for 4-5 days or freeze for up to 3 months. I like to reheat portions in the microwave for 2-3 minutes, covered, until bubbly. For the crispy topping, bake it separately for 2 minutes at the end if you want extra crunch. Serve with a simple green salad or steamed veggies—the contrast makes it a meal. Leftovers? Perfect for lunches—just reheat and enjoy!

Step-by-step instructions for creamy tuna casserole

This one-pan wonder delivers cheesy crunch perfection with minimal effort—just follow these simple steps!

Bring a large pot of salted water to a rolling boil—it should taste like the sea. Add the 2 cups elbow macaroni and cook for 10-11 minutes until al dente (a toothpick should slide in with slight resistance). Drain thoroughly in a colander, shaking to remove excess water. I like to give it a quick rinse under cold water to stop the cooking process immediately—this prevents a mushy casserole later.

While the pasta cooks, open the 2 cans Campbell's Cream of Mushroom Soup and set aside. The soup will form the creamy base of our casserole, so we'll use it straight from the can for that authentic, comforting flavor. Don't worry about adjusting seasoning here—the soup already has just the right balance of salt and umami.

In a large mixing bowl, combine the drained macaroni with the 2 cans canned tuna (drained if in oil) and 2 cups sharp cheddar cheese. Use your hands to break up any large chunks of cheese and distribute it evenly throughout the pasta. This ensures every bite has that melty, gooey goodness we all love. Add the 0.5 tsp garlic powder and 0.5 tsp onion powder now—they'll infuse the tuna and pasta with warm, savory depth.

Next, pour in the 2 cans Campbell's Cream of Mushroom Soup and stir until the mixture is completely coated. The soup should look slightly thickened but still pourable. If it seems too thin, we'll fix that in the next step. Taste a spoonful at this point—you might want to adjust with a pinch of salt or black pepper if needed, though the soup and cheese usually provide enough flavor.

In a separate bowl, whisk together the 0.5 cup milk, 0.25 cup all-purpose flour, and 0.25 cup melted butter until smooth. This slurry is what transforms our creamy base into a rich, velvety sauce. Pour this mixture into the tuna-pasta bowl and stir vigorously for 2-3 minutes over medium heat (if using a pot) or let it sit while you preheat your oven. You'll see the sauce thicken noticeably as the flour absorbs the liquid—this is what gives classic casseroles that perfect, clingy texture.

Real talk: If the sauce looks too thick, add 1-2 tablespoons of milk to loosen it. We want it to coat the back of a spoon but still be pourable enough to distribute evenly in the baking dish. The goal is a sauce that's thick enough to hold its shape when sliced but still creamy enough to coat every bite of pasta.

Preheat your oven to 375°F while you transfer the tuna mixture to a 9x13-inch baking dish, spreading it evenly. The dish should be about ¾ full—this gives the casserole room to rise slightly without overflowing. Sprinkle the 0.5 cup panko breadcrumbs evenly over the top, pressing down lightly with your fingers. This creates that irresistible crispy crust we all crave.

Bake uncovered for 25-30 minutes until the top is golden brown and the edges are bubbling. The casserole is done when the cheese is fully melted and the panko has turned a beautiful golden color. If you're worried about the top browning too quickly, tent loosely with aluminum foil for the last 10 minutes of baking—this keeps the cheese from over-browning while still letting it melt perfectly.

Remove the casserole from the oven and let it rest for 10 minutes before serving. This resting time allows the layers to set slightly, making it easier to slice cleanly. The cheese will continue to melt and the flavors will meld together—this is when the magic really happens. For the best experience, serve with a side of steamed green beans or a simple garden salad to balance the richness.

Cut into squares and watch as the creamy tuna filling oozes out with every bite. The crispy panko topping should contrast perfectly with the soft, cheesy interior. Leftovers? They're even better the next day—just reheat in the oven at 350°F until warmed through, covered with foil to prevent drying out.

Best sauces and condiments for this recipe

Creamy Mushroom Sauce Upgrade

Start with the Campbell's cream of mushroom soup as your base, but take it to the next level by adding 2 tablespoons of Dijon mustard and 1 teaspoon of Worcestershire sauce to the sauce mixture.

These ingredients add depth and complexity that elevate the dish from classic to extraordinary. The mustard brightens the richness, while Worcestershire brings a savory umami punch that complements the tuna perfectly. 💡

Garlic-Herb Butter Sauce

For a richer, more aromatic sauce, melt 3 tablespoons of butter in a saucepan and sauté 2 minced garlic cloves until fragrant. Stir in 1 teaspoon dried thyme and 1 teaspoon dried parsley, then whisk in the Campbell's soup.

This infusion transforms the sauce into a fragrant, herbaceous base that pairs beautifully with the tuna and pasta. Use this instead of the milk-butter slurry for a more luxurious texture.

Creamy Ranch Dressing Twist

Mix 2 tablespoons of ranch dressing (like Hidden Valley) directly into the Campbell's soup before combining with the tuna and pasta. This adds a tangy, herby note that cuts through the richness of the cheese.

For extra flavor, use 2 tablespoons of homemade ranch—just blend ½ cup sour cream, ½ cup mayonnaise, 1 teaspoon onion powder, and 1 teaspoon dried dill. The result is a creamy, herby sauce that feels fresh and modern. 🥛

Spicy Kick with Hot Sauce

If you love a little heat, stir 1 tablespoon of hot sauce (like Frank's RedHot) into the Campbell's soup before mixing with the tuna. For a smoky twist, add ½ teaspoon smoked paprika along with the hot sauce.

This adds a subtle depth that pairs surprisingly well with the cheesy, creamy texture. Serve with extra hot sauce on the side for those who want more heat.

Cheesy Sauce Boost

For a saucier, extra-cheesy version, replace the milk-butter slurry with a mix of ½ cup sour cream and ½ cup shredded cheddar cheese. Stir this into the Campbell's soup before combining with the tuna and pasta.

The result is a thicker, creamier sauce that clings to every bite. This version is especially rich and satisfying, perfect for cold nights or when you're craving extra comfort. 🧀

Topping Variations

While panko breadcrumbs are classic, try these alternatives for your topping: For extra crunch, mix ¼ cup crushed potato chips (like Ruffles) with the panko. For a cheesy crunch, sprinkle ¼ cup grated Parmesan cheese over the top before adding the breadcrumbs.

For a smoky flavor, add ½ teaspoon smoked paprika to the breadcrumb mixture. Each variation adds a unique texture and flavor profile to your casserole. 🔥
