Ingredients for Tuna Casserole Recipe with Mushroom Soup

Old-fashioned comfort in a baking dish. Egg noodles, tuna, and creamy soup come together effortlessly.

The tuna is the backbone here—wild-caught canned tuna in water (like Bumble Bee or StarKist) gives the best texture. Don’t skimp on the cream of mushroom soup; Campbell’s is the classic choice, but store brands work fine. For the noodles, Reames frozen egg noodles save time, but dried works too (just boil them first). The cheese should melt beautifully—Sargento or Cabot sharp cheddar are reliable picks.

No cream of mushroom soup? Cream of celery or chicken (if you’re not strict pescatarian) works in a pinch. Fresh mushrooms and a white sauce can mimic it if you’re feeling fancy. Out of peas? Frozen mixed vegetables or corn add color and texture. The potato chip topping is non-negotiable for that nostalgic crunch, but buttered breadcrumbs or cracker crumbs work if you’re fresh out.

Assemble and bake right away, or refrigerate up to 24 hours before baking. Leftovers keep 3-4 days in the fridge and reheat beautifully. The casserole freezes well for up to 2 months—just thaw in the fridge overnight before reheating.

Step-by-Step Instructions for Tuna Casserole with Mushroom Soup

Here’s how I create this comforting dish with a modern touch, layer by layer.

Step 1: Cook the Egg Noodles to Al Dente Perfection

Bring a large pot of salted water to a rolling boil. Add the 8 oz Egg Noodles and cook according to package instructions until just al dente—about 1 minute less than the recommended time. You want them slightly firm because they’ll continue cooking in the oven.

Drain the noodles in a colander and rinse briefly under cold water to stop the cooking process. Shake off excess water and set aside. This prevents them from turning mushy when baked later. I always taste one to confirm it’s tender with a slight bite—this texture holds up best in the casserole.

Step 2: Sauté the Vegetables for Depth of Flavor

In a large skillet over medium heat, melt the 2 tbsp Unsalted Butter. Add the finely diced Yellow Onion and finely chopped Celery Stalks, then sauté for 5 minutes until the onion turns translucent and the celery softens.

Sprinkle in the 2 tbsp All-Purpose Flour and stir constantly for 1 minute to cook off the raw flour taste. This creates a light roux that will thicken the sauce slightly. Add the 1 cup Frozen Peas (thawed and drained) and cook for another 2 minutes to warm them through. Season with the 0.5 tsp Salt, 0.5 tsp Garlic Powder, and 0.5 tsp Onion Powder.

Step 3: Combine All Ingredients into a Creamy Mixture

In a large mixing bowl, combine the 2 cans Canned Tuna (drained and flaked), 2 cans Cream of Mushroom Soup (undiluted), and 1 cup Whole Milk. Stir until smooth and fully incorporated. The soup provides a rich, creamy base, while the milk thins it just enough for a velvety consistency without being too thick.

Add the cooked egg noodles and sautéed vegetable mixture to the bowl. Fold everything together gently to avoid breaking the noodles. Stir in 1 cup Shredded Cheddar Cheese (reserving 0.5 cup for topping) until the cheese melts into the mixture. The result should be a creamy, cohesive filling with visible flecks of tuna and vegetables.

Taste and adjust seasoning if needed, adding a pinch more Salt or 0.25 tsp Black Pepper to suit your preference.

Step 4: Bake Until Bubbly and Golden

Transfer the mixture to a greased 9×13-inch baking dish and spread it evenly. Sprinkle the remaining 0.5 cup Shredded Cheddar Cheese over the top, followed by the 1 cup Potato Chips (lightly crushed). The chips add a crunchy, buttery topping that contrasts beautifully with the creamy filling.

Bake in a preheated 375°F oven for 25-30 minutes, or until the casserole is bubbling around the edges and the top is golden brown. If the potato chips start browning too quickly, tent the dish loosely with foil. Let it rest for 5 minutes before serving—this allows the filling to set slightly for easier portioning.

Wine and Beer Pairings for tuna casserole recipe with mushroom soup

Crisp White Wines

A chilled Chardonnay with bright acidity cuts through the creaminess beautifully. I love Kendall-Jackson Vintner’s Reserve—its citrus notes complement the tuna without overpowering. Serve at 45-50°F for best results. 🍷

Light Red Options

For red wine lovers, try a light-bodied Pinot Noir like Meiomi. Its red fruit flavors and subtle earthiness pair well with the mushroom and tuna. Avoid heavy, tannic reds that will clash with the creamy sauce.

Classic Beer Pairings

A crisp American lager like Budweiser or Coors Banquet cleanses your palate between bites. The carbonation and mild bitterness balance the richness perfectly. Serve ice cold in a frosty mug. 🍺

Craft Beer Alternatives

For craft beer fans, a Kolsch or Hefeweizen offers interesting contrast. The light, slightly fruity profile of Bell’s Oberon works wonderfully with the casserole’s savory notes.

Non-Alcoholic Choices

Sparkling water with a squeeze of lemon provides a refreshing, alcohol-free option. I also enjoy iced tea—unsweetened or lightly sweetened—to complement the dish’s comforting flavors.
