What Ingredients are in Easy Tuna Casserole?

This tuna casserole recipe is the epitome of comfort food – simple, satisfying, and made with pantry staples most of us already have on hand. The beauty of this dish lies in its straightforward ingredient list, which combines protein-rich tuna with creamy soup and tender pasta. Perfect for busy weeknights when you need something filling without a lot of fuss.

  • 2 (6 ounce) cans tuna in water, drained
  • 1 (10 1/2 ounce) can cream of mushroom soup
  • 1 (10 1/2 ounce) can mushrooms
  • 1 (16 ounce) package shell pasta
  • 1/2 to 1 cup milk (to desired consistency)
  • Black pepper (to taste)
  • Garlic salt (to taste)
  • Potato chips (for topping)
  • Optional: peas or carrots

The flexibility of this recipe is what makes it so approachable. Don’t have shell pasta? Any medium pasta shape will work just fine. The milk amount is adjustable depending on how creamy you prefer your casserole. And while the recipe suggests potato chips for that delightful crunchy topping, you could substitute crushed crackers or breadcrumbs if that’s what you have. The optional vegetables like peas or carrots can add color, nutrition, and texture—but they’re completely up to you, making this truly a customizable family meal.

How to Make this Easy Tuna Casserole

comforting customizable tuna casserole with crunchy topping

Making this tuna casserole couldn’t be simpler, and it’s perfect for those evenings when you want something comforting without a lot of fuss. Start by cooking your 16-ounce package of shell pasta according to the directions on the package, then drain it well. While the pasta is cooking, drain two 6-ounce cans of tuna packed in water. In a large pot, combine your drained tuna with a 10½-ounce can of cream of mushroom soup and a 10½-ounce can of mushrooms, giving everything a good stir to combine.

Next comes the customization part, which is where you can really make this recipe your own. Add anywhere from ½ to 1 cup of milk to reach your desired consistency—less for a thicker casserole, more if you prefer it a bit saucier. Season the mixture with black pepper and garlic salt to taste (because honestly, what dish isn’t improved with a little garlic?). You might want to go easy on the salt at this stage, allowing everyone to adjust the seasoning at the table. While you won’t need premium fishing gear for this recipe, you’re still enjoying the fruits of expert tuna fishing. Let the whole mixture simmer for 5-10 minutes, stirring occasionally so nothing sticks to the bottom of the pot.

For serving, I recommend topping each portion with a sprinkle of crushed potato chips. This might sound a bit unusual if you haven’t tried it before, but that extra crunch adds such a satisfying textural contrast to the creamy casserole. And don’t be afraid to make this recipe your own—many people like to add frozen peas or diced carrots for a pop of color and extra nutrition. Green vegetables look so pretty against the creamy background, and they add a nice freshness to balance the richness.

Easy Tuna Casserole Substitutions and Variations

The beauty of this easy tuna casserole lies in its flexibility—you can swap ingredients based on what’s lurking in your pantry or fridge. Don’t have shell pasta? Any medium pasta shape works beautifully. Rotini, bow ties, or even macaroni make perfect substitutes.

For the protein, canned salmon or chicken can replace tuna if that’s what you’ve got on hand. Not a mushroom fan? Swap in cream of celery or cream of chicken soup instead.

Veggies are totally customizable too. While the recipe suggests peas or carrots as additions, I’m partial to frozen mixed vegetables or even some chopped broccoli for extra nutrition. And those potato chips on top? Try crushed crackers, breadcrumbs, or even french-fried onions for that essential crunchy topping.

What to Serve with Easy Tuna Casserole

Wondering what complements a steaming dish of tuna casserole? This comforting classic actually works beautifully as a complete meal, especially with those crushed potato chips sprinkled on top for that perfect crunch factor.

For a well-rounded dinner, I like to pair it with a crisp green salad dressed simply with vinaigrette. The fresh, tangy greens balance the creamy richness of the casserole, trust me.

Steamed broccoli or roasted asparagus make excellent veggie sides too, adding color and nutrition to your plate.

For bread lovers, warm garlic bread or buttery dinner rolls are ideal for sopping up any extra sauce. And don’t forget a chilled white wine or iced tea to wash it all down. Simple, satisfying, and no fuss!
